Frequently Asked Questions

Do you service systems you didn’t install?

Yes. We service most CCTV, alarm and access control systems, even if installed by another company.

How often should a security system be serviced?

Most systems should be checked annually. Commercial premises may require more frequent servicing depending on insurance requirements.

How much does a system service cost?

Each system service is priced based on how long it will take and what type of system it is. Please contact us for our pricing.

What does the service include?

Your service visit covers:

  • System inspection

If faults require additional time or parts, this is quoted separately.

We do not rush repairs, and we do not cut corners.
