The initial design stage will often require a site visit or service visit to assess and identify the requirements. An up-to-date Fire Risk Assessment will determine the relevant category needed for a Domestic or Non-Domestic premises.

There are a variety of system types such as conventional, analogue addressable, wireless, hybrid systems and aspirating smoke detection systems. We endeavour to offer advice to our customers on what is required to make a system compliant.

We provide a detailed written quotation, usually valid for 20 days. The quotation will specify the type of system being proposed and will itemise all the parts, labour and relevant British Standards.


On approval of the quotation, we will schedule the works with you and order the necessary parts for your project.

Depending on the scale of the work, it can be completed in one phase, or be phased across a number of visits.
