We support Hertfordshire properties with AOV, fire, electrical and security through our accredited in-house engineers, covering Watford, St Albans, Stevenage and Hertford. BAFE, NICEIC, IFC SDI 19 and SafeContractor accredited.
We bring AOV and smoke ventilation, fire safety, electrical testing and security together under one contractor, giving property managers a single team for the systems that need regular inspection, testing, servicing and maintenance.
Our Hertfordshire coverage includes individual residential buildings and larger property portfolios, with engineers supporting properties across towns including Watford, St Albans, Stevenage, Hemel Hempstead, Welwyn Garden City, Hatfield, Hitchin and Hertford.
Our work is backed by BAFE SP203-1, NICEIC Approved Contractor, IFC SDI 19 and SafeContractor credentials. Every job is delivered by BLEC’s own engineers rather than subcontractors.
