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.

When should the electrician start?

First fix runs right after the plumber, before plaster boarding. We'll coordinate the dates with your builder.

Home Extension Electrics in Henley on Thames

Extension & Loft Electrical Work for Henley-on-Thames homes across RG9, from a Buckinghamshire-based electrician who covers Oxfordshire on a weekly rota.

A Thameside market town on the Oxfordshire bank, known for the Royal Regatta. That mixture matters because it drives what a typical extension wiring visit here actually involves: riverside period houses, georgian and victorian townhouses in the centre, and larger detached homes towards the surrounding villages. The routing choices, cable ages and consumer unit types you find in Henley-on-Thames homes aren't the same as one town over, and neither is the way we plan the job.
