New build extension under construction ready for electrical first fix

Electrics for new builds, start to finish

Whether you’re building a single house, a small development of flats or a large extension, we take care of the whole electrical installation — not just a few sockets at the end. We plan the electrics around your drawings, work to your builder’s programme and leave you with a fully certified installation that’s ready for building control sign-off.

DESIGN & QUOTEWe go through your plans, agree socket, lighting, data and appliance positions and give a fixed written quote.
FIRST FIXCables, back boxes, containment and circuits run through the frame, blockwork and floors before plastering.
SECOND FIXConsumer unit, sockets, switches, lighting, extractor fans, smoke and heat alarms fitted and connected.
TEST & CERTIFYEvery circuit tested, Electrical Installation Certificate issued and the work notified to building control through NAPIT.

What we install on new builds

  • New supply arrangements and meter tails, coordinated with your network operator and supplier
  • Consumer units with RCBO and surge protection
  • Kitchen circuits — cooker, hob, oven, extractor and appliance points
  • Lighting design — LED downlights, pendants, under-cabinet and outdoor lighting
  • Mains-wired, interlinked smoke, heat and carbon monoxide alarms
  • Data and TV points, door entry and doorbell wiring
  • EV charger and outdoor socket provision
  • Shower circuits, extractor fans and bathroom lighting with the right IP ratings

Working with builders and developers

We’re used to working on site with builders, plasterers, plumbers and kitchen fitters. First fix is done on time so plastering isn’t held up, second fix is booked around decorators, and we keep you updated throughout. For developers and landlords building to let, we can also provide EICRs and ongoing maintenance once the property is occupied.

Extensions, loft conversions and refurbishments

The same approach works for rear and side extensions, loft and basement conversions and full refurbishments — new circuits designed around how you’ll use the space, with the certification building control needs.

Outstanding Service & Expertise! I recently hired this electrical engineer and I am beyond impressed with the quality of work delivered. From the very beginning, they were punctual, professional, and extremely knowledgeable. Every task was completed with precision and great attention to detail, ensuring everything was fully safe and compliant. They took the time to explain what needed doing, answered all my questions clearly, and offered smart solutions that saved both time and cost. The final result was flawless, neat wiring, tidy workspace, and everything working perfectly. It’s rare to find someone who combines technical expertise with excellent customer service, but they exceeded my expectations on every level. I will definitely be recommending them to friends, family, and anyone who needs reliable electrical work. An easy 5 stars!

I needed a light put up in my dining room. He arrived on time(on same day I called), worked quickly and professionally, and completed the job to a very high standard. I was impressed by his attention to detail and efficiency. Even better, his pricing was very fair and reasonable. I highly recommend his services and will definitely call him again for any future work.

X electricians are a great, reliable electrical company. I requested that they come over to help replace a faulty fuse switch, and they sent someone over on the same day! They helped buy me a new switch, replace the old switch and checked to make sure that everything was working again. The efficient electrician who helped us was very polite and hardworking and helped resolve our issue. I could not recommend them enough if you need help with any electrical issues. 10/10 Would recommend!

New build questions

Do you do the whole installation or just parts of it?

Either. Most clients want us to handle everything from first fix to final certificate, but we can also take on second fix or testing only where another electrician has started.

Do you work from architect’s drawings?

Yes — send us your plans and electrical layout (or we can help you plan one) and we’ll give a fixed written quote.

Do I get certificates for building control?

Yes. You get an Electrical Installation Certificate, and as a NAPIT-registered firm we notify the work to building control for you.

Do you cover new builds outside North West London?

We mainly work across North West, West and Central London and South Hertfordshire. Get in touch with the site address and we’ll let you know.
