Security and Fire System Design and Installation

In order to establish your precise requirements we need to carry out a survey of the premises you are looking to secure. A survey is carried out by one of our surveyors who will visit the premises and assess the risk, and design a system that’s fit for purpose. Our in house design team is experienced in planning systems that comply with the relevant regulations. We carry out a full survey and appraisal of each customers’ individual requirements and then design a system that meets your need and budget. At the same time we will ensure that the installation is sympathetic to its surroundings.

Security and Fire System Maintenance and Repairs

Our dedicated team of access control service engineers is on call 24 hours, 7 days a week. We can normally respond to an emergency call-out within 24 hours and very often the same day if contacted before midday. All engineer’s vans carry a stock of the most common replacement parts so that often the repair can be completed during a single visit. Once fully repaired we offer you the option to take out a preventative maintenance service agreement to ensure that your system is properly maintained to prevent future breakdowns.
  • We aim to provide our customers with the highest level of service from start to finish; from the moment you meet our expert friendly surveyors for your free survey, to our highly skilled engineers, through to our dedicated customer service team who are just a phone call away.
