If your insurance documents or building handbook still mention BS 4737, we translate that into practical recommendations for today’s standards and grades. Many older panels remain serviceable short-term but lack modern signalling, power supervision or parts availability. We can keep them working where sensible, or design a replacement that reuses cabling and improves detection. Facilities managers inherit mixed estates—we standardise reporting and phased upgrades so risk and cost stay controlled. Share any existing certificates or insurer clauses when requesting advice.
