Finding a qualified electrician in Swansea requires checking two things: their membership of a Government-approved Competent Person Scheme (NICEIC, NAPIT, or ELECSA) and their insurance. Everything else — price, availability, reputation — is secondary to these two fundamentals, because electrical work in the UK must either be certified by a scheme member or approved by building control, and uncertified electrical work creates problems when you sell your property.
Electrician costs in Swansea
Electrician rates in Swansea in 2026 range from £40 to £75 per hour for standard domestic work. Most Swansea electricians work to a minimum call-out charge of one to two hours. The most common jobs and their typical all-in costs:
| Job | Typical cost (Swansea, 2026) |
|---|---|
| Consumer unit (fuse box) replacement | £450–750 |
| New socket installation | £80–250 (depends on cable run) |
| EV charger installation | £600–1,200 (OZEV grant available) |
| Full house rewire (3-bed) | £3,000–6,000 |
| EICR (electrical safety inspection) | £150–250 |
| Outside socket or lighting circuit | £200–400 |
| Smoke/CO alarm installation | £80–200 per alarm |
Swansea electrician rates are broadly similar to Cardiff but anecdotally slightly lower in some areas of the city, particularly for smaller jobs. The city's mix of Victorian terraces in the Uplands, 1960s semis in Sketty and Killay, and newer developments in SA1 creates a range of typical jobs.
Part P Building Regulations in Swansea
Part P of the Building Regulations covers electrical safety in dwellings. It applies to all electrical work in homes in Swansea — including garages, outbuildings, and garden circuits. The key points:
Notifiable work (requires certification or building control notification):
- New circuits
- Consumer unit (fuse box) replacement
- Work in special locations: bathrooms, kitchens near water, outdoors
- Addition of sockets, lighting, or other accessories to circuits in special locations
Non-notifiable work (no certification required):
- Like-for-like replacement of accessories (sockets, switches, light fittings) on existing circuits in normal rooms
- Repair of existing circuits outside special locations
How certification works in Swansea: A NICEIC, NAPIT, or ELECSA member can self-certify their own work — they issue a Building Regulations Compliance Certificate directly. This is legally equivalent to building control approval. Non-member electricians must notify City and County of Swansea's building control department before starting notifiable work (and pay the associated fee). The self-certification route is faster and usually cheaper.

Common electrical jobs in Swansea homes
Consumer unit replacement The most common large electrical job in Swansea is replacing an old fuse box (consumer unit) with a modern unit featuring RCD (or RCBO) protection. Modern units provide much better shock and fire protection. Cost: £450–750 installed, including the Part P compliance certificate. Most Swansea electricians complete this in 4–6 hours.
EV charger installation EV charger installations are growing rapidly across Swansea as more residents switch to electric vehicles. A dedicated 7kW home charger typically takes 2–4 hours to install and costs £600–1,200 total. The OZEV grant (up to £350) is available to homeowners with off-street parking — confirm your chosen installer is OZEV-approved before booking.
Smoke and CO alarm upgrades Since January 2022, Welsh regulations (The Smoke and Carbon Monoxide Alarm Regulations 2022) require landlords to fit smoke alarms on every floor and a CO alarm in every room with a solid fuel appliance. Owner-occupiers are not legally required to fit them, but they are strongly recommended. A Swansea electrician can fit mains-wired (hardwired) alarms that are more reliable than battery-powered units.
EV charger installation in Swansea
EV charger installation in Swansea requires a qualified electrician, ideally one registered with OZEV (Office for Zero Emission Vehicles) to access the government grant scheme.
Grant eligibility:
- You must own or lease an eligible electric vehicle
- You must have off-street parking at your home
- The charger must be from an OZEV-approved list
- Grant value: up to £350 off the installed cost
What to ask your Swansea electrician:
- Are you OZEV-approved?
- Does your quote include the OZEV grant application, or do I need to apply separately?
- Is the charger included in the price, or quoted separately?
- Will the installation require any ducting or cable trenching? (this adds cost)
- Can the charger be tethered (cable attached) or untethered (socket)? What do you recommend for my vehicle?
Most OZEV-approved Swansea electricians handle the grant application on your behalf as part of the installation.
Swansea electrician FAQs
Do I need a certificate for replacing sockets in Swansea? It depends. Replacing like-for-like (same position, same circuit) sockets in normal rooms does not require a Part P certificate. Adding new sockets, or any socket work in a kitchen or bathroom, does require either a Competent Person Scheme certificate or building control notification.
How do I find a NICEIC-approved electrician in Swansea? Visit niceic.com and use the "Find a contractor" search. Enter "Swansea" or your postcode. You can also check NAPIT members at napit.org.uk and ELECSA members at elecsa.co.uk.
How much does an EICR cost in Swansea? An Electrical Installation Condition Report (EICR) in Swansea typically costs £150–250 for a standard 3-bedroom house. Larger or more complex properties cost more. Landlords must have an EICR every 5 years (or at each change of tenancy) — it is a legal requirement for private landlords in Wales under the Renting Homes (Wales) Act 2016.
Can I install my own sockets in Swansea? You can legally replace like-for-like accessories (same position, existing circuit) without certification. Adding new circuits or moving existing ones is notifiable under Part P and requires a Competent Person Scheme member or building control notification. Bathroom electrical work always requires a certified electrician.
What is the 18th Edition and does it apply to Swansea? Yes. BS 7671:2018 (18th Edition of the IET Wiring Regulations, updated by Amendment 2 in 2022) is the standard that all new electrical installations in Swansea must meet. Your electrician should be trained to the current edition — look for City & Guilds 2382-22 or equivalent certification.
