Buying electronic security to secure your premises is a very important decision, whether for domestic or commercial premises. It is essential that the products you choose give the protection you want. It is equally important that the quality of the installation work, and the ongoing service you receive from the installation company, meets proven industry standards. NACOSS approves companies in the electronic security sector across the British Isles. Insurers have been very impressed with the way NACOSS has raised standards. For domestic installations, many insurers will offer discounts for electronic security systems installed by a NACOSS Recognised Firm. Commercial organisations should be aware that insurers often insist on security systems installed by a NACOSS Recognised Firm before they will provide cover.
