Fitted our house with a security alarm and changed the locks on some doors

Verified Review

Security is so important to me so when we moved getting an alarm was the first thing on my list. Nick at GPM came highly recommended to us by my brother who has used GPM for years. They sorted everything out for us and quickly. Everyone I dealt with from Nick, to the team who installed everything and the office staff were efficient and friendly. Highly recommend them.

Additional work to the security system installed in June 2020

Verified Review

We had a security system installed in June and a few bits needed to be adjusted and updated - all done very efficiently again - both Peter and Kirk were professional and kept us informed. All now completed and yet again I would definitely recommend GPM London. That you Nick, Kennedy, Sarah and the team..
