Our Services
Domestic electrical installation covers new work in your home: extra circuits for an extension, a kitchen refit, garden power or a loft conversion. We plan the cable runs, fit everything to the 18th Edition rules and test it before we leave. See our domestic installation page for details.
Shops, offices, salons and workshops all need electrics that can take a full day's load. Our commercial electrical installation work covers new circuits, distribution boards, lighting and sockets. We can work outside opening hours so your business in Oxford keeps trading. Read more on our commercial installation page.
A home EV charger is faster and safer than charging from a three pin plug. We check your supply, fit a dedicated circuit and install a smart charger in a handy spot near your parking. Charging at home in Oxford then becomes part of your normal routine. Our EV charger page has the full detail.
Too few sockets often leads to extension leads and stacked adaptors, which can overheat. We add new sockets, move old ones and fit USB sockets where you need them. Each one is wired and tested properly before we finish. Visit our socket installation page to find out more about the options.
An electric shower pulls a lot of power, so it needs its own circuit with the right size of cable and protection. We fit new showers and upgrade old ones, checking first that the supply can handle the rating. Find out how the job works on our electric shower installation page.
Mains wired smoke alarms that link together give everyone in the house the earliest possible warning. When one goes off, they all sound. We fit smoke, heat and carbon monoxide alarms for homeowners and landlords across Oxford. Our smoke alarm installation page explains the options in more detail.

Most small installations, like new sockets or a smoke alarm, take a few hours. A new circuit for a shower or EV charger usually takes a day. Larger jobs, such as an extension or a commercial fit out, can take several days. We give you a clear timeframe with your free quote so you can plan ahead.
Yes. We wire kitchens, extensions and loft conversions across Oxford. We work with your builder so the cables go in at first fix, before plastering, then come back to fit sockets, switches and lights at second fix. Everything is tested and certified once the room is finished and ready to use.
