Home extensions are booming right now. With moving costs through the roof and the housing market the way it is, more and more homeowners in Brighton and Hove are choosing to extend rather than move. Whether it's a rear kitchen extension, a loft conversion, or a side return, it's a big project — and one where the electrical side of things is often the most overlooked part of the whole build.
I get called in on a lot of extension jobs, and the same story comes up time and again. The builder is booked, the plans are drawn up, the kitchen is chosen — and then someone asks: "When do we need an electrician involved?"
The answer, honestly, is as early as possible. Let me explain why.
Don't Leave the Electrics as an Afterthought
It's easy to focus on the exciting bits — the layout, the bi-fold doors, the new flooring. Electrics aren't glamorous, but they're the backbone of how the whole space actually functions day to day.
Getting an electrician involved early means:
- Sockets, switches, and lighting go exactly where you want them
- You avoid having to chase out walls or lift floors after they've just been finished
- Any consumer unit upgrades are planned for and budgeted properly
- Everything is signed off correctly without delays at the end of the build
I've seen plenty of extensions where the electrician has been called in right at the end, and it causes headaches — walls that have already been plastered need opening up, things end up positioned awkwardly, and it costs more time and money than it needed to.
What's Actually Involved in Extension Electrics?
Every job is different, but for a typical home extension in Brighton or Hove, the electrical work usually covers a few key areas.
First fix — this is the early stage, before walls are plastered. Cable is run through the walls, floor, and ceiling to all the positions agreed in advance. Sockets, light switches, downlights, extractor fans — anything that's going in the walls or ceiling gets its cable routed at this point. Get this stage right and the rest follows smoothly.
Second fix — once plastering is done and the space is ready, this is when everything gets fitted. Sockets, switches, light fittings, extractors — all the visible stuff goes in at this stage.
Consumer unit assessment — this is something a lot of people don't think about until they're told about it. Your existing fuse board has a certain capacity, and adding a whole new part of the house to it might push things. In some cases, an upgrade is needed. In others, it's fine as it is. Either way, it's something I'll check early so there are no surprises.
Certification — all electrical work on an extension needs to be certified under Part P of the Building Regulations. As a registered electrician, I handle this as part of the job. You'll get the correct documentation, which you'll need if you ever sell the property.
What About Older Properties?
Brighton and Hove has a huge amount of older housing stock — Victorian terraces, Edwardian semis, period flats. They're beautiful homes, but the existing electrical installations can be a mixed bag.
If your property has older wiring or an outdated consumer unit, now is actually a great time to address it. An extension project naturally means disruption anyway, so it often makes sense to sort out any underlying electrical issues at the same time rather than leaving them for later.
I'll always be upfront about this. If I spot something that needs attention, I'll explain what it is, why it matters, and what it'll take to put it right — in plain English, no jargon.
Lighting in Extensions — Worth Thinking About Early
One thing people consistently underestimate is the difference good lighting planning makes to a finished space.
Extensions — especially open-plan kitchen extensions — benefit hugely from layered lighting. That might mean recessed downlights for general lighting, under-cabinet lighting in a kitchen, pendant lights over an island or dining area, and maybe some feature lighting for atmosphere. All of that needs to be planned and cabled at first fix stage.
If you leave it too late and just end up with a single ceiling rose in the middle of the room, you'll regret it. It's one of the most common things I hear from people after the fact — "I wish we'd put more thought into the lighting."
Working Alongside Your Builder
I'm used to working as part of a wider build team and coordinating with builders, joiners, and other trades. Good communication between trades makes for a smoother job and a better result — and it's something I take seriously.
If you've already got a builder lined up for your extension, I'm happy to make contact with them directly and make sure everyone is working to the same programme. It keeps things moving and avoids those frustrating situations where one trade is waiting on another.
