Electrician costs in Caerphilly
Electrician costs in Caerphilly are broadly in line with the wider South Wales market. Day rates run £180–300 for a qualified domestic electrician. Call-out charges for minor repairs start from £60–100 before labour. For larger jobs — consumer unit replacement, rewires, EV charger installation — quotes are typically fixed price.
| Job | Typical cost |
|---|---|
| Call-out + first hour | £80–150 |
| Day rate | £180–300 |
| Consumer unit replacement | £350–650 |
| Full rewire (3-bed house) | £3,000–6,000 |
| EV charger installation | £700–1,200 |
| New circuit (sockets or lighting) | £150–350 |
| EICR (3-bed house) | £150–300 |
Always get at least two written quotes for any job over £300. For a consumer unit replacement or rewire, confirm that the quote includes the cost of building control notification (or that the electrician will self-certify through their Competent Person Scheme membership).
Part P and NICEIC — what the certifications mean
Part P of the Building Regulations (Electrical Safety in Dwellings) is the legal framework that governs domestic electrical work in Wales. It specifies which work is "notifiable" — meaning it must either be self-certified by a qualified electrician or approved by your local authority's building control department.
Notifiable work includes:
- Installation of new circuits anywhere in a dwelling
- Consumer unit (fuse board) replacement
- Any electrical work in a bathroom, kitchen, or outdoors
- Installation of outdoor lighting or socket circuits
Work that is generally not notifiable includes like-for-like replacement of accessories (adding a socket on an existing circuit, replacing a light fitting) in normal rooms.
NICEIC, NAPIT, and ELECSA are the three main Competent Person Schemes for domestic electricians in Wales. Electricians registered with these schemes can self-certify notifiable work, issuing a completion certificate that is legally equivalent to building control sign-off. When your electrician gives you an Electrical Installation Certificate, keep it — you will need it when you sell the property.
To verify an electrician's registration, check the relevant scheme's online register. NICEIC's register is at niceic.com, NAPIT's at napit.org.uk.
Common electrical jobs in Caerphilly homes
Caerphilly's housing stock is dominated by post-war semi-detached and terraced houses, alongside newer estate builds from the 1980s–2000s. The area around the town centre and historic Caerphilly Castle has older terraced housing; the surrounding valleys have a mix of inter-war and post-war properties.
Consumer unit replacement: Many Caerphilly homes built before 1990 still have older fuse boards with rewirable or cartridge fuses rather than modern MCBs (miniature circuit breakers) and RCDs (residual current devices). Upgrading to a modern consumer unit improves safety significantly and is typically required before home insurance companies will insure a property with an old-style fuse board. Cost: £350–650.
EV charger installation: Rapid growth in electric vehicle ownership has made home EV charger installation one of the most requested electrical jobs in South Wales. A Caerphilly electrician will assess your existing supply capacity, install a dedicated circuit and outdoor socket, and register it with building control. Many installations qualify for the OZEV (Office for Zero Emission Vehicles) grant — ask your electrician whether you qualify. Cost: £700–1,200 including survey and registration.
EICR (Electrical Installation Condition Report): Landlords in Wales are legally required to have an EICR carried out every five years. For owner-occupiers, it is strongly recommended when buying a property or if the installation is more than 25 years old. An EICR for a 3-bedroom house in Caerphilly typically costs £150–300.
Rewires: Full rewires are needed when existing wiring is aluminium (common in 1960s–1970s properties), has degraded rubber insulation (pre-1950s properties), or has failed an EICR badly enough to warrant full replacement rather than remedial work. A full rewire of a 3-bedroom house in Caerphilly costs £3,000–6,000, including first fix, second fix, and all certification.
Outdoor and garden circuits: Adding outdoor sockets, garden lighting, shed power, or hot tub circuits requires a dedicated circuit from the consumer unit and RCD protection. This is notifiable work and must be certified. Cost: £150–400 per circuit depending on distance and complexity.
What to check before booking
- Competent Person Scheme membership: Check the electrician is registered with NICEIC, NAPIT, or ELECSA at the scheme's online register
- Part P compliance: Confirm they will provide an Electrical Installation Certificate for all notifiable work
- Public liability insurance: Ask for proof — minimum £2 million for electrical contractors
- Written quote: For any job over £200, request a written, itemised quote
- VAT status: Confirm whether the quoted price includes VAT
- Timeframe: For larger jobs, confirm the expected duration and whether disruption to power is expected
- Building control notification: Confirm how the job will be notified (self-certification or building control approval)
Caerphilly electrician FAQs
Do I need a qualified electrician for all electrical work in Caerphilly? Not all electrical work requires a fully qualified electrician, but anything involving new circuits, consumer units, or work in bathrooms, kitchens, or outdoors is legally notifiable under Part P Building Regulations. For this notifiable work, you need either a Competent Person Scheme member (NICEIC, NAPIT, ELECSA) or local authority building control approval.
How much does a consumer unit replacement cost in Caerphilly? A standard consumer unit replacement in Caerphilly costs £350–650, including the unit, installation, testing, and Electrical Installation Certificate. This assumes the existing wiring is in good condition — if remedial work is needed first, the cost will be higher.
Is an EICR required to sell a house in Caerphilly? There is no legal requirement for owner-occupiers to have an EICR before selling. However, if the buyer's solicitor or surveyor identifies old wiring or a failed EICR as a concern, it may become a condition of the sale. It is increasingly common for buyers to request an EICR as part of their due diligence, particularly for properties over 25 years old.
How do I know if I need a rewire in Caerphilly? Key indicators that a rewire may be needed: wiring with rubber insulation (pre-1960s, the rubber often degrades to a dangerous state), aluminium wiring (1960s–1970s installations), a failed EICR with multiple Category 2 or Category 1 observations, or persistent tripping of circuits. A local NICEIC-registered electrician can assess and give you an honest opinion.
What is the Competent Person Scheme and why does it matter? The Competent Person Scheme allows registered electricians to self-certify their own notifiable work, eliminating the need for a separate building control inspection. This speeds up the process and reduces cost. The certificate issued by a Competent Person Scheme member is legally equivalent to building control sign-off and must be passed on to the buyer when you sell your property.
