If you’re planning an extension or major renovation this year, it’s tempting to think about electrics last — after the walls are up and the layout is settled. In practice, getting an electrician involved early saves both money and headaches.
Why early planning matters
Sockets, lighting circuits, and any new appliances need to be planned before plastering, not squeezed in afterwards. Retrofitting wiring into finished walls is more disruptive and more expensive than running cables while everything’s still open.
1. Check your consumer unit has capacity
An extension often means additional circuits — extra sockets, lighting, possibly a new kitchen or utility room. Your existing consumer unit may need additional capacity or an upgrade to handle the extra load safely.
2. Plan socket and lighting positions with the finished room in mind
Think through furniture layout, TV positions, and where you’ll actually plug things in before first fix wiring goes in — moving a socket after plastering is far more disruptive than moving a plan on paper.
3. Consider future-proofing while walls are open
While the work is already underway, it’s a good time to consider extras that are far more disruptive to add later — additional data points, USB sockets, outdoor lighting circuits, or pre-wiring for an EV charger even if you’re not getting one immediately.
4. Certification matters for building control sign-off
Electrical work on extensions typically needs to be certified to meet Building Regulations Part P. Using a qualified electrician from the start avoids sign-off complications later.
5. Get your electrician and builder talking to each other
The best results come from your electrician and main contractor coordinating directly on timing — first fix wiring needs to happen at the right point in the build, not squeezed in around other trades.
