Short answer. Pick something a customer can spell after hearing it once on the phone, that does not lock you into one town or one service, and that clears a trade mark search. Everything else is taste. The names that cause real problems are the ones implying an accreditation you do not hold.
Six patterns that work
These are patterns, not names to copy. Any specific name you like has to be checked against the four tests further down, because somewhere in the country somebody is probably already trading as it.
1. Your surname plus the trade
The most durable option and the least used. It cannot be confused with a competitor, it survives you changing what you specialise in, and it is the easiest kind of name to protect legally. It also makes every review read as a review of a person, which is exactly what a customer letting somebody into their house wants.
2. An electrical word plus an ordinary noun
Volt, amp, circuit, current or spark combined with a plain second word. It signals the trade immediately and leaves room to grow. The risk is saturation: these are the most heavily used roots in the industry, so the search before you commit matters more here than anywhere.
3. Something geographic but larger than your town
A county, a river, a range of hills, a compass direction. It roots you locally without confining you to one high street, which matters if you might cover four towns in five years' time.
4. A specialism, if you are certain
Naming yourself after EV charging, testing or commercial work is a powerful filter and a real commitment. It wins you the customers you want and quietly closes the door on the others. Only do it if you would be happy doing that work exclusively for a decade.
5. A neutral abstract word
A short, pronounceable word with no meaning attached, which you then make mean something. Hardest to establish, easiest to protect, and the only pattern that lets you become anything later.
6. Initials, but carefully
Initials work when they are already yours and fail when they are invented, because a three-letter combination is almost impossible to remember and usually taken as a domain. If you use initials, pair them with a real word.
The words that create problems
A business name is an advertising claim as much as a label, and UK advertising rules apply to it. Anything implying accreditation you do not currently hold is the danger area:
- Approved, certified, registered, accredited. Fine if true and evidenced, a problem if not, and the claim follows you into every search result and every invoice.
- A scheme name you are not registered with. Using NICEIC, NAPIT or a similar name in your business name is not yours to do.
- Government, official, national, authority. Some of these are sensitive words at Companies House and need permission.
- Guaranteed, cheapest, number one. Superlatives you would have to be able to prove if challenged.
Our compliance guide covers what you can and cannot claim in more detail, including scheme logo usage.
The four checks, in order
- Companies House. Search the register for the name and for near-identical variants. Free, instant, and it tells you whether the name is available to incorporate.
- The trade mark register. Search the Intellectual Property Office register. This is the check that stops a letter arriving in three years' time, and it is the one most people skip.
- An ordinary search. Look for sole traders using the name informally without a company behind it. They will still be a problem for your customers, and possibly for you.
- Domain and social handles. Do this last. A name is worth compromising on for the first three checks and rarely worth abandoning for the fourth, because a slightly different domain is a smaller cost than a slightly wrong name.
Two practical tests before you sign anything
The phone test. Say the name aloud to somebody who has never heard it, then ask them to write it down. If they get it wrong, every customer who hears it from a neighbour will end up somewhere else.
The ten-year test. Imagine the business with four vans, doing commercial work in a county you do not currently cover. Does the name still fit? If it does not, you have chosen a name you will pay to replace.
One last thing worth knowing: your business name matters far less than what customers find when they search it. A perfect name attached to nothing loses to an ordinary name attached to a real profile and a site that answers questions.
