Short answer: A UK electrician's website has to answer four questions fast: are you registered, what jobs do you take, do you cover my area, and can I see your work? Answer those on the first screen and most of what is left is detail. Miss them and a recommended electrician still loses the call to the one whose site answered.
Most electrical work comes through a recommendation. The customer then looks you up, and the site has about ten seconds to confirm what they were told.
Show your registration first
In England, most electrical work in homes falls under Part P of the Building Regulations. Electricians usually show they are competent by belonging to a scheme such as NICEIC or NAPIT, which lets them certify their own work. Put the scheme logo and your registration number near the top, with a line on what it covers. Customers are told to ask, so answer before they do.
Split domestic and commercial
A homeowner wanting extra sockets and a facilities manager needing a contractor read different things. Give each its own page and its own enquiry form. Domestic pages should talk about consumer units, rewires, EV chargers and fault finding. Commercial pages should talk about testing, emergency lighting and response times.
List the jobs, one page each
"Electrician" is too broad to rank for. "Consumer unit upgrade", "EICR report" and "EV charger installation" are what people actually search. Give each a short page with what is involved, how long it takes and a price range if you can state one. If you have added solar or battery storage, that deserves its own page too, because it is a separate search from general electrical work.
Name your patch
Name the towns you cover, not just the county. It brings the right calls and cuts the ones you would decline.
Real photos, real jobs
A photographed new consumer unit with tidy labelled circuits does more than a paragraph of promises. Show finished work with the town and the job type. Never use stock images. A customer who has seen three stock-photo sites can spot a fourth.
A form that lets you quote without a visit
Ask what you would ask on the phone: the job, the property type, and a photo of the fuse board or the area. Small jobs can then be quoted from the message and only the large ones need a visit.
Where to go next
If you want this built for you, with no payment until you have seen it live, our electrician website service is set up around these pages, and the UK electricians page has the pricing. If you are comparing routes first, how much a website costs for a small UK business lays out each option.
