Highlights
"Having had the system installed in February 2023 this latest visit was for the third annual service and as usual Paul and Morris were punctual and respectful whilst in the property undertaking the work. We have always been impressed with NJS Ltd ever since Neil originally visited in early 2023 to outline the system they would be installing to suit our requirements. I would recommend Neil, Gina, Paul and Morris if anyone is seeking security system in their home. Thanks again"
"Burglar alarm service"
"Excellent job undertaking by two excellent workmen of fitting alarm system to home premises"

Smart checks
Before you hire an electrician
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.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
