Highlights
“Slate were one of five companies that we got quotes from, this was for two small blocks of flats that were showing damp inside many of the flats. their quote was the best - albeit by pennies - but when we met Carl Slate the penny dropped. As an association, we have to get a RAMS report done by any contractor, and these are always a hassle. But Carl was very much up to date with on-site safety, which is the first time that's happened! So he won the contract, and the work was excellent. Thorough and clean, and all the flats are reporting a massive improvement in damp. Job Done!”
“Very good service; helpful team who made some good suggestions as to why original damp was occurring.”

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 13 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.
