> "Emilio sunk all of our sockets/switches and added new sockets downstairs for us. He was really tidy, kept us well informed and reasonably priced. He was really quick with getting the work done and ended up taking money off as he was finished before expected which was great. He was well equipped and answered all of our questions, we had complete trust in him. I highly recommend Praevius."

> "Praevius sorted out my home automation. They were very prompt and explained everything really well. The lighting control system is impressive and if I move house I’ll definitely be contacting them again. They were professional, efficient and cleaned up after themselves. I would recommend them to anyone needing home automation."

## Before you hire an electrician
_What to check when choosing this kind of trade — general guidance, not a claim about this business:_
- In 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.
- Look for consistent reviews across several named sources, not one polished profile.
- Check any credential evidence, and that the business details independently check out.
