Regular Maintenance For Home Security Systems

The UK security industry’s independent regulatory body, the National Security Inspectorate (NSI), recommends that security systems are kept regularly maintained. This is to ensure that any potential malfunctions are spotted before they compromise the system and that your home protection remains fully functioning.

An alarm system that fails can leave you vulnerable to break-ins and render your insurance invalid. The police also insist that any security system they monitor must be maintained by a company with a police recommended accreditation, such as NSI Gold.

Spy Alarms is fully qualified to provide regular maintenance for our own installations and those installed by other companies.

Benefits Of Maintenance Contracts

The benefits of keeping your home security system maintained by Spy include:

  • 24/7 Call Outs – No matter when you need us, we’ll be there.
  • Any system – Our service covers home security systems that we have installed and the takeover of systems installed by other suppliers.
  • NSI Gold accreditation – We provide a high quality, reliable service that is recognised by the police and all insurers.
  • Saves cost – Maintenance visits cost less than emergency call outs and our local focus enables us to keep our costs very competitive. Should an emergency call-out be necessary, it will be heavily discounted for customers on a maintenance contract. Our NSI Gold accreditation can also help to reduce your insurance premiums.
  • Convenience – We will book our maintenance visits at a time that suits you.
  • Fast response – We guarantee to send an engineer out to maintenance customers within four hours.
