Home Extension Electrics in Great Missenden
Bringing a extension wiring up to current standards in Great Missenden usually means starting with the installation you have, not the one a brochure imagines.
Period cottages in the conservation area, larger inter-war and post-war family houses on the surrounding lanes. Some are wired to a good standard already; others still carry decades-old fuse boards, buried junction boxes and cabling that predates modern accessory ranges. We'll walk it through with you, share the readings, and give you an option that's proportionate to the property — not the biggest quote we can write.

Planning your extension's electrics with the builder
- 1
Coordinate with the builder
We agree first-fix timing with your builder and mark up socket and switch positions once studs are in.
- 2
First fix
Cables run through joists and studs, back boxes fitted, and any new circuits terminated at the consumer unit ready for testing.
- 3
Second fix and test
Accessories fitted after plaster, everything tested and certified as part of the new circuits under BS 7671.
Questions we get asked most
- Will the new work be certified?
- Yes, as new circuits under BS 7671 with a full initial verification test.
- Do you handle data cabling too?
- We can run Cat6 to the extension while the walls are open, so points are neat and hidden.
- Do we need a bigger consumer unit?
- Sometimes. If there are no spare ways, we either fit a new unit or add a small sub-board fed off a suitable circuit.
- Can we plan for future EV charging?
- Yes — we can pull a spare conduit or cable now, so a future charger is a switch-on job.
