Extension and Conversion Electrics in Wallingford
Reliable extension wiring across Wallingford and the surrounding Oxfordshire villages within a practical service radius.
The Wallingford coverage area we work in most weeks stretches into Benson, Didcot, Cholsey and Crowmarsh Gifford. Journey times from our base in High Wycombe (HP11) are short enough that same-week visits are the norm rather than the exception. The work itself — extension wiring — is one of the things we take on for domestic customers day-to-day, not a sideline.
Based at 14 Kelly Road, High Wycombe HP11 1BW. Domestic only.

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
- What about the existing kitchen circuits?
- If they're being reshaped, we plan and re-terminate them so nothing ends up buried behind a new stud wall.
- 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.
- 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.
