Electrician in Cardiff: 10 Local Options for Repairs, Rewiring and Electrical Testing

Electrical work is not the place for vague comparisons. A failed socket, a landlord’s EICR, a full rewire and an EV-charger installation all need a different conversation before anyone starts work. The right electrician is not automatically the one with the biggest review number or the shortest headline about being local.The Cardiff Local Guide team starts with the job and its consequences.

Is the power fault urgent? Do you need certification? Is an older property being rewired? Are you adding an EV charger, outdoor supply or new consumer unit? Once that is clear, the shortlist becomes more useful because you can compare like with like.

Cardiff is where Welsh tradition meets a modern urban centre in motion, and electrical work sits across that whole mix: older housing, city-centre businesses, student and rental properties around Cathays, family homes across the City and County of Cardiff, and new installations connected to changing energy use. The local setting matters, but it does not prove that a contractor covers every Cardiff neighbourhood or can attend immediately. Confirm the address, access, certificate requirements and appointment window directly.

Before you call, have these details ready:

• What has failed, and is there any burning smell, sparking, heat or exposed wiring?
• Is the work a repair, installation, inspection, upgrade or full/partial rewire?
• Do you need an EICR, landlord certificate, PAT testing or another document?
• Is the property domestic, commercial, rented or being renovated?
• Are you asking for an EV charger, solar-related work, fire alarm, outdoor power or lighting?
• Do you need a written quote, an emergency response or a fixed appointment?

Do not reset a repeatedly tripping circuit or investigate damaged wiring yourself. If there is immediate danger, isolate the supply if it is safe to do so and use the appropriate emergency route. For planned work, a precise brief will produce a more useful quote than simply asking, “How much to do electrics?”

The quick Cardiff shortlist

Best for published pricing and broad technical scope: MJP Electrical. It publishes an urgent call-out price of £171 plus VAT including the first hour and a standard rate of £57 plus VAT, with materials excluded.

Best for rewiring: Cardiff Electrical Home Rewire Ltd. Its stated focus is full and partial rewires, backed by a 4.9/5 rating from 57 Google reviews, NICEIC approval and a six-year warranty claim.

Best review evidence for general installation work: Williams Electrics. It shows 5.0 from 95 Which reviews presented, with a Cardiff address and domestic/industrial service scope.

Best broad local showroom-and-electrician operation: Budd Electrical / Budd Electricians. Its scope includes fault finding, consumer units, alarms, CCTV, EV charging, solar PV, EICRs and PAT testing.

Best for 24/7 emergency call-outs: Electricall South Wales. Its service page states round-the-clock emergency call-outs, alongside domestic, commercial and landlord work.

Best for Canton and CF5 locality: Gabe Electrical South Wales Ltd. It provides a Cardiff CF5 signal, a registered office on Cowbridge Road East and a broad domestic/commercial menu.

Best for a high-volume review signal: MJP Electrical. Its business page states 4.9/5 from 760 customer reviews, though the figure remains a business-page claim.

Prices are not available for most providers. Where no figure is supplied, pricing is available on consultation. Ratings, accreditations and review counts should be checked against the specific job, not treated as a guarantee of outcome.

Ten Cardiff electricians compared by practical fit

1. MJP Electrical — the clearest choice when pricing transparency matters

Positioning

MJP Electrical stands out because it gives the customer more concrete commercial information than most of the other Cardiff profiles. Its Cardiff area page describes NICEIC electrical work for residential and commercial customers, including emergency call-outs, EICRs, consumer-unit upgrades, rewires, EV charging and solar PV.

The stated pricing is £171 plus VAT for an urgent call-out including the first hour, with a standard rate of £57 plus VAT. Materials are excluded. That does not make MJP the cheapest option; it makes the starting structure easier to understand before the first conversation.

Two strengths

The first strength is price clarity. A customer can ask a better question when the call-out and hourly basis are visible. Confirm whether the rate applies to the specific Cardiff job, how travel is treated and how materials or certification are charged.

The second is the breadth of the technical menu. Rewires, EICRs, consumer units, EV chargers and solar PV cover both urgent faults and planned upgrades. The business page also states NICEIC approval, insurance and 18th Edition qualification signals.

Best fit and operational reality

MJP suits a homeowner, landlord or business that wants to compare a clearly priced contractor for emergency work, testing or planned electrical upgrades. The page states same-day/emergency service and online booking, but the actual appointment window remains job-dependent.

The business serves a wider South West and South Wales geography, so confirm Cardiff routing and availability rather than assuming the nearest engineer is local. The review figure is 4.9/5 from 760 customer reviews on the business page; the source and current count should be checked at booking. Ask for a written scope, VAT treatment, materials estimate and certification arrangements. Published starting rates above; final price available on consultation.

2. Cardiff Electrical Home Rewire Ltd — the strongest rewire-led profile

Positioning

Cardiff Electrical Home Rewire Ltd is the clearest specialist choice for a customer considering a full or partial rewire. Its service information names rewires, consumer-unit upgrades, EICRs, EV chargers, fault finding, lighting and emergency call-outs. The business identifies itself as Cardiff-based with a CF14 base and says it works across Cardiff and South Wales.

The rewire focus matters because a full electrical renovation is not the same as adding a socket or replacing a light fitting. The scope, access, certification, making-good expectations and staging should all be set out before work begins.

Two strengths

The first strength is direct service alignment. Rewiring is not buried inside a long list of unrelated trades; it is central to the business identity. That makes it a logical first enquiry for an older home, renovation or property needing a full electrical review.

The second is the stated compliance and warranty position. The business says it is a NICEIC Approved Contractor, works to BS 7671 and provides a six-year NICEIC warranty. Those are meaningful signals, but the customer should still ask which parts of the work the warranty covers and what certificate will be issued.

Best fit and operational reality

This provider suits homeowners, landlords and renovation projects where the electrical system needs more than a small repair. It may also suit customers who want EICR or consumer-unit work discussed alongside a rewire.

The supplied profile shows 4.9/5 from 57 Google reviews and offers free, no-obligation quotes. The full street address is not supplied, only a CF14 base, and the business also covers Penarth, Barry, Newport and wider locations. Confirm Cardiff availability for the property. Ask about chasing walls, access, temporary power, making good, certification, warranty terms and the final price. Pricing available on consultation.

3. Williams Electrics — a well-reviewed Cardiff-addressed option

Positioning

Williams Electrics has a clearly stated address at 7 Llyswen Road, Cyncoed, Cardiff, CF23 6NG. It is described as handling domestic and industrial electrical installations and testing, including consumer units, rewiring, lighting, sockets and external lighting or power to garages and sheds.

The profile is particularly useful for a customer who wants a specific Cardiff address combined with a review record. It is not presented as a specialist-only rewire or emergency contractor, so the job still needs to be described accurately. That makes it a practical comparison point for planned work rather than an automatic answer to every electrical problem.

Two strengths

The first strength is the review signal: 5.0 across 95 Which reviews presented is the strongest review evidence in this shortlist. The profile also shows 5.0 for customer service, quality, value and recommendation, giving more detail than a single overall score.

The second is the range of ordinary property work. Consumer units, sockets, lighting and external power cover common domestic needs, while industrial installation and testing broaden the potential commercial fit.

Best fit and operational reality

Williams Electrics suits Cardiff homeowners and industrial customers who want a local-addressed contractor with substantial public review evidence. It may be a strong option for planned work, testing, lighting or a consumer-unit discussion rather than an assumed 24-hour emergency service. That distinction is useful when the customer can plan the visit and wants the work explained clearly.

The published schedule is Monday to Friday 08:00–18:00, with weekends closed. No public price schedule is supplied. The business was established in 2009, and the profile says staff have many years of electrical/electronic industry experience. Ask whether the required certificate is included, how external runs are priced, what happens with making good and whether urgent work is available outside published hours. Pricing available on consultation.

4. Budd Electrical / Budd Electricians — broad domestic and light-commercial coverage

Positioning

Budd Electricians provides one of the broadest service menus in the Cardiff data. The profile gives a Cardiff showroom at 118–120 Caerphilly Road, Cardiff, CF14 4QG, and describes qualified domestic and light-commercial work. The list includes fault finding, lighting, sockets, consumer units, fire alarms, CCTV, outdoor electrics, EV charging, solar PV, EICRs and PAT testing.

That breadth is useful, but it also means the customer should avoid making assumptions. A long service list is a starting point for questions, not evidence that every electrician in the business handles every specialist installation. A contractor that offers many services still needs to confirm the exact team, certification and equipment for the job in front of you.

Two strengths

The first strength is coverage across routine and specialist property needs. A landlord can ask about EICR and PAT testing, while a homeowner may need lighting, sockets, EV charging or outdoor power. Fire alarms, CCTV and solar-related services widen the conversation further.

The second is the stated qualification and registration signal. The business says it uses qualified electricians and is NAPIT registered. Registration should be checked against the specific work and current status, particularly where certification or installation standards matter.

Best fit and operational reality

Budd suits homeowners, landlords and light-commercial customers wanting one Cardiff-based business to discuss several electrical systems. It may be particularly useful where inspection, installation and small works overlap.

Electrician hours are listed as Monday to Friday 09:00–17:00, with the showroom also opening Saturday 10:00–16:00. Those are published business hours, not a promise that an electrician can attend at any point. No public rating, review count or job-price schedule is confirmed in the supplied data. Ask whether the showroom address is the booking base, which electrician will attend, what certification is supplied and whether EV, solar or alarm work is quoted separately. Pricing available on consultation.

5. Reliable Electricians Cardiff — a broad domestic, commercial and industrial service

Positioning

Reliable Electricians Cardiff presents itself as a Cardiff electrician serving domestic, commercial and industrial customers. The service list covers installation, repair and maintenance, rewires, consumer units, kitchen and garden electrics, fault finding, testing, landlord certificates and EV chargers.

The broad customer mix makes this a useful option for a property owner who needs more than a single small job. However, the supplied page does not provide a Cardiff street address, so the local signal is service-based rather than a confirmed customer-facing premises.

Two strengths

The first strength is the range across property types. A domestic repair, landlord certificate and commercial installation can be very different in paperwork and scheduling; the profile at least signals capability across those categories.

The second is the stated approval and qualification position. The page identifies an ELECSA-approved and City & Guilds-qualified team. Those claims should be checked against the specific electrician and the current scheme status before relying on them for a regulated or certified job.

Best fit and operational reality

Reliable Electricians Cardiff may suit homeowners, landlords and businesses looking for a broad first enquiry, particularly where rewiring, consumer units, testing and EV charging sit in the same brief. It also states that free home safety checks are available. That can be a useful first step when the customer knows something is wrong but does not yet know which repair or upgrade is required.

The business page shows 5.0 from 20 reviews, but the review source and current count should be confirmed. No Cardiff street address, postcode, full opening schedule or exact job prices are confirmed in the supplied data. Ask whether the free safety check includes a written report, whether certificates are part of the quote and how emergency availability differs from planned work. Pricing available on consultation.

6. Electricall South Wales — the clearest emergency-led option

Positioning

Electricall South Wales is presented as offering electricians in and around Cardiff, with domestic, commercial and landlord electrical work. Its service list includes repairs, wiring, testing, installation, fuse boards and EV chargers. The public page specifically describes 24/7 emergency call-outs.

That makes the profile relevant to urgent faults, but a round-the-clock service statement does not mean every job is immediately available or that the same rate applies at every hour. Emergency work should be discussed in terms of safety, response window and likely first-stage diagnosis.

Two strengths

The first strength is the emergency signal. Customers with a serious electrical fault need to know whether an out-of-hours route exists; this provider states one clearly.

The second is the combination of urgent and planned work. Fuse boards, wiring, testing, landlord work and EV chargers give the customer somewhere to go if an emergency visit reveals a wider issue. It may be possible to discuss the repair and the follow-up scope with the same business, subject to confirmation. Ask whether the first visit is diagnosis, repair or both.

Best fit and operational reality

Electricall suits Cardiff households, landlords and businesses that need an urgent repair route or want to discuss electrical work beyond a single light or socket. It may be useful where emergency attendance and later testing need to connect. That is especially relevant when a temporary repair could lead to a larger planned job.

No Cardiff street address, published rating, review count or fixed price is confirmed in the supplied data. The page says a quote is available, but the amount is not supplied. Ask what qualifies as an emergency, whether the call-out includes diagnosis only, what materials may cost and which certificate will follow a repair. Pricing available on consultation.

7. Gabe Electrical South Wales Ltd — the strongest Canton and CF5 locality signal

Positioning

Gabe Electrical South Wales Ltd has a registered office at 374 Cowbridge Road East, Cardiff, CF5 1JJ, and a dedicated Canton page identifying local electricians serving Canton CF5 and other parts of Cardiff. The page says the company visits customers’ premises rather than operating as a simple walk-in service location.

The service menu is broad: rewires, EV charging, EICRs, sockets, lighting, fuse-box upgrades, emergency work and commercial installations. It is a useful profile for customers who want local Cardiff relevance without assuming the business is limited to one neighbourhood.

Two strengths

The first strength is the specific Canton/CF5 signal. A named Cardiff locality and postcode make the profile more concrete than a generic “South Wales” service page, although coverage for the full City and County of Cardiff still needs to be confirmed for the job. It gives the customer a useful local starting point without turning the postcode into a promise of faster attendance.

The second is the domestic-to-commercial range. Rewires, EV chargers, EICRs and emergency work cover household and landlord concerns, while commercial installations extend the possible brief. The business also states clear, upfront pricing, although no amounts are published.

Best fit and operational reality

Gabe suits Canton and CF5 customers, homeowners, landlords and small businesses wanting a contractor with a clear Cardiff identity and broad electrical scope. It may be useful for planned upgrades as well as urgent enquiries.

The page claims five-star electricians and refers to 90+ clients, but the exact rating, review count and source are not confirmed in the supplied data here. It states operation since 2015 and provides an NICEIC registration signal. Ask whether the registered office is relevant to attendance, whether the quote includes certification, what “upfront” means in practice and how emergency work is priced. Pricing available on consultation.

8. APP Electrical & Fire Ltd — a wide electrical and fire-systems menu

Positioning

APP Electrical & Fire Ltd names Cardiff among its core service locations and describes residential and commercial installation, repair and testing. The scope includes rewires, lighting, outdoor electrics, EICRs, consumer units, EV charging, smart homes, emergency work and fire or emergency lighting.

This is a useful option when electrical work connects to fire systems or a commercial premises rather than a single domestic repair. The business also serves Pontyclun, Caerphilly and wider South Wales, so Cardiff should be confirmed as the active location for the specific appointment. That wider footprint is relevant when discussing travel, response time and who will attend.

Two strengths

The first strength is the breadth of the service menu. Smart-home work, EV charging, consumer units, EICRs, fire lighting and rewires create several possible routes for a property owner planning an upgrade.

The second is the accreditation signal. The supplied profile links to Which? Trusted Trader and NAPIT/Trustmark information. It also claims more than 200 five-star ratings on Google and Which combined, but the platform split and current totals are not confirmed in the supplied data.

Best fit and operational reality

APP suits homeowners, landlords and commercial customers whose brief combines electrical installation with inspection, EV, emergency or fire-lighting requirements. It may also suit a larger project where several systems need coordinating.

The company was incorporated in 2021, but the operating-history duration is not confirmed in the supplied data. No Cardiff street address, postcode, ordinary hours or exact prices are supplied. Ask which accreditation applies to the electrician attending, what the EICR or fire-lighting paperwork includes, whether emergency work is available in Cardiff, how materials are handled and whether the fire-lighting element needs a separate inspection. Pricing available on consultation.

9. CAG Electrical Ltd — a Cardiff CF11 contractor with clear quotation signals

Positioning

CAG Electrical Ltd gives a Cardiff location at First Floor, Wellington House, W2 Business Centre, Cardiff, CF11 9BE. Its public information says it serves homeowners, landlords, letting agents and businesses. The service menu includes EICRs, fault finding and repairs, consumer-unit upgrades, EV chargers, lighting, sockets, full and partial rewires and emergency call-outs.

The profile is especially relevant to a customer who wants planned work explained before it starts. The business says it provides clear written quotations for planned work, although no price figures are published.

Two strengths

The first strength is the combination of a Cardiff CF11 location and a broad customer base. Homeowners, landlords, letting agents and businesses may need different paperwork and access arrangements, and the page recognises those audiences.

The second is the stated professional status. The business identifies itself as a NICEIC Approved Contractor and refers to a JIB Approved Electrician. Those are useful signals for a customer comparing certification-led work, but they should be confirmed for the current job and person attending.

Best fit and operational reality

CAG suits Cardiff landlords, homeowners and commercial customers needing EICR, fault finding, rewiring, consumer-unit or EV work. It may be a good fit where a written scope matters more than a quick informal estimate.

The site says it is open Monday to Sunday 24 hours, but this is a published business-hours claim and does not establish that all appointments are available immediately. Confirm whether the number is monitored overnight and whether emergency attendance has a separate charge. The company also covers Newport and wider South Wales, so confirm Cardiff scheduling. No rating, review count, years in business or exact prices are supplied. Ask whether emergency pricing differs, what the written quote excludes and which certificates follow completion. Pricing available on consultation.

10. Lightwork Electrical — a wide-service contractor with qualification signals

Positioning

Lightwork Electrical describes itself as based near Cardiff and serving the wider South Wales area. Its menu includes domestic and commercial contracting, inspection and testing, upgrades, emergency work, EV chargers, fault finding, rewires, lighting, PAT testing, smoke alarms and fuse-board replacement.

The profile is therefore useful for a customer whose job could sit anywhere between a small domestic repair and a broader property upgrade. Its value is range, but the quote still needs to separate inspection, installation and follow-up work. It does not provide a Cardiff street address, so the local relationship should be treated as service-area information rather than a confirmed Cardiff premises.

Two strengths

The first strength is the coverage of both everyday and project work. PAT testing, smoke alarms and lighting sit alongside emergency repairs, EV chargers and rewires, giving landlords and small businesses several relevant entry points.

The second is the qualification and registration evidence. The profile refers to NAPIT registration, City & Guilds, ECS and EAL qualifications, and links to Checkatrade and TrustATrader. It also states more than 12 years of industry experience and a Checkatrade rating of 10/10, although the review count is not supplied.

Best fit and operational reality

Lightwork suits Cardiff-area households and businesses wanting a qualified contractor for a broad range of work and prepared to request a job-specific quote. It may be particularly useful for landlords or commercial customers combining inspection with maintenance.

The business offers a free quote and describes pricing as transparent, with rates varying by job and travel. No Cardiff street address, full opening schedule or exact figures are supplied. Emergency or after-hours support is stated, but routine hours are not confirmed in the supplied data. Ask how travel is calculated, which accreditation covers the work, whether PAT and smoke-alarm tasks are separate and what certification is included. Pricing available on consultation.

FAQ: choosing an electrician in Cardiff

Which Cardiff electrician is best for a full rewire?

Cardiff Electrical Home Rewire Ltd has the clearest rewire-led positioning and states NICEIC approval, BS 7671 compliance and a six-year warranty. MJP Electrical, Gabe Electrical, CAG Electrical and Lightwork Electrical also list rewires, but their wider service menus mean you should confirm who will manage the rewire and what making-good or certification is included.

How much does an electrician cost in Cardiff?

Only MJP Electrical provides concrete starting rates in the supplied data: £171 plus VAT for an urgent call-out including the first hour, and £57 plus VAT as a standard hourly rate, excluding materials. Other providers offer quotes or describe pricing as clear without publishing figures. Ask for the call-out, labour, materials, VAT, certification and any follow-up visit to be separated.

Who offers 24/7 emergency electrical call-outs?

Electricall South Wales describes 24/7 emergency call-outs, MJP Electrical describes same-day/emergency availability, and CAG Electrical and Lightwork Electrical also publish emergency or out-of-hours signals. None of those statements guarantees immediate attendance. Explain the fault, location and safety risk and ask what the emergency fee covers.

Do I need an EICR in Cardiff?

The requirement depends on the property and situation, particularly for rented accommodation and specific electrical responsibilities. The supplied providers offering EICRs include MJP Electrical, Cardiff Electrical Home Rewire Ltd, Budd Electricians, Reliable Electricians Cardiff, Gabe Electrical, APP Electrical, CAG Electrical and Lightwork Electrical. Ask for the correct inspection scope and the certificate you will receive; do not book an ordinary repair expecting it to substitute for an EICR.

Can an electrician install an EV charger at my Cardiff property?

Several shortlisted providers list EV charging: MJP Electrical, Cardiff Electrical Home Rewire Ltd, Budd Electricians, Reliable Electricians Cardiff, Electricall South Wales, Gabe Electrical, APP Electrical, CAG Electrical and Lightwork Electrical. Confirm the charger model, survey, cable route, consumer-unit capacity, certification and any external work before comparing prices.

Does living near Cardiff Central or Cardiff Queen Street affect which electrician I choose?

The stations are useful Cardiff orientation points, but the provider data does not confirm that any contractor is based at either station or that a particular route is included in a service radius. Give the electrician the complete property address, access instructions and parking or loading constraints if relevant. Do not use a station’s location as proof of local coverage.

What if my property is in Cathays, Canton or Cardiff Bay?

These are distinct Cardiff areas, and the providers vary in how specifically they describe their coverage. Gabe Electrical has a dedicated Canton/CF5 signal; other businesses describe Cardiff more broadly. Confirm the exact address and appointment availability. Cathays, Cardiff Bay and Cardiff city centre should not be treated as interchangeable service locations.

What should I ask for in a written electrical quote?

Request the exact tasks, materials, labour basis, VAT, testing and certification, making-good responsibilities, exclusions, warranty terms, emergency charges and expected timescale. If the job involves Cardiff Council premises, a landlord, a commercial unit or a property close to a busy city-centre route, explain that context at the start rather than adding it after the quote.
