Residential alarm maintenance agreements

Regular inspections and maintenance can often prevent faults from developing and pre-empt issues with your home security system which might otherwise require an unwanted expensive emergency call-out visit by an engineer.

Regular inspections and maintenance can often prevent faults from developing and pre-empt issues with your home security system which might otherwise require an unwanted cost for a fault call-out visit.

Customers with a maintenance agreement have access to our 24-hour technical helpline and will be guaranteed a response within four hours if one is required.

Maintenance agreement customers are always given priority for system fault calls over those who do not have an agreement. If you do not have an agreement in place we will be happy to talk to you during our office hours between 08:30 – 17:30, Monday to Friday.

We offer three intruder alarm maintenance agreements for you to choose from depending on your requirements and budget. You will be invited to renew your agreement annually so you will never find yourself tied into a contract for more than 12-months.
