We used to get an annual service in January each year but for several years have to ring them in order to get it done. Last year service was in April after bringing them, this year August again after reminding them. Engineer came and was very thorough but just after he left the alarm activated even when it wasn’t set. Rang and they isolated a zone, told they would ring me back to come and rectify but five days later nothing. Rang them again to sort it out and told it would be three weeks before they can come to rectify. Considering how expensive they are the service is appalling. Steve Vickers
