Domestic Electrical

Home Extension Electrics

Extension electrics from circuit design through first fix and second fix to testing, certification and building control sign off, worked around your builder's programme.

An extension is one of the few times a home gains entirely new circuits, and the electrical decisions have to be made earlier than most people expect. Cable routes are set at first fix, which lands between the structural work and the plasterer, so the socket plan, lighting scheme and consumer unit question all need answering before the walls close up.

We work directly with your builder rather than through you, so dates get agreed once and the programme holds. Notifiable work is certified properly, and you finish with the paperwork a buyer's solicitor will ask for years later.

Common reasons customers call us

Your builder needs an electrician who can hit a first fix date.

You want the lighting planned before the ceiling goes up, not after.

You are not sure whether the existing fuse board can take the new circuits.

You need building control sign off handled without chasing anybody.

The extension adds a kitchen, utility or bathroom with real load behind it.

Frequently asked questions

When should I book the electrician?

As soon as the build has dates. First fix has a narrow window and it holds up the plasterer if it slips.

Do you deal with building control?

Notifiable work is certified through our registration, and we coordinate with the wider building control application on the build.

Will I need a new consumer unit?

Only if the existing board lacks capacity, protection or fails testing. We check before anything is ordered.

Do you work with our builder directly?

Yes, that is normally quickest. We agree the programme dates with them and keep you copied in.
