 Trustindex verifies that the original source of the review is Google. Great service. Called at midnight in desperation as my house burglar alarm kept going off. Alex came within 20 minutes and stayed over an hour finding the fault then carefully dismantling the faulty aspects. He was also very nice and friendly to deal with

Helped silence the outside alarm and checked that the internal alarm had been appropriately disconnected. Explained what the issue was and resolution process.

Very good, professional service and recommended.

Our house security alarm went off constantly due to low battery and kids couldn’t sleep but Alex came straightaway all the way from the other side of London to rescue us at 1:30am. Super reliable and simply a life saver for us! Thank you very much.
