Perhaps your present alarm system is not covered by a maintenance contract, your current provider's costs and charges are excessive or the alarm needs modification or upgrading. We would be pleased to talk to you about taking over your existing system. We guarantee:

Any take-over system will automatically have brand new external sounds / decoy sounders fitted at no extra cost.

We guarantee same day service to all faults reported and within a maximum of 4 hours if outside normal working hours.

All take-over systems will have complete recommissioning and new system documentation issued as standard.

Any modifications/upgrades we recommend to the system will be submitted in writing with costs prior to take-over.


Your system will have a brand new battery fitted in the Control Panel, as standard, and at no extra cost.

All systems maintained annually (twice per annum if a monitored system) by appointment with customer (weekends, if preferred, at no extra cost).

The annual maintenance charges will be kept in line with our set charges for our own installed systems, i.e. no extra cost for take over.

All annual charges are currently fixed for a minimum of two years.

Our contracts provide for comprehensive cover, including parts. Although we carry spares for most systems, if we don't have a replacement we will fit a new alternative.
