“Very good experience with Marnzies, quick communication and booking, punctual, quality work; will definitely use them again. Our electrician Jack quickly assessed what was needed and worked out where and how to access wiring from the walls behind kitchen cabinets so the repairs could be hidden and no decor work needed. Jack also explained what he would do before getting on with the job so we were completely comfortable with the result. Bonus points for being dog-friendly :)”

Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 20 years on the register also points to an established business rather than a brand-new one.

Electrical work in homes in England & Wales should be done by a registered competent person who can self-certify it meets the Part P safety rules. Check they're on the official register.
Check the electrical registerIn England and Wales, notifiable electrical work (new circuits, a consumer unit, anything in a bathroom or kitchen) must by law be signed off under Part P of the Building Regulations. Confirm they will handle that.
Prefer an electrician registered with a government-approved competent-person scheme (NICEIC, NAPIT or ELECSA) so they can self-certify the work meets the wiring regulations.
Insist on the Electrical Installation Certificate (or Minor Works Certificate) when the job is done. It is your proof the work is safe and compliant, and you will need it if you ever sell.
