What to think about in Harpenden
England and Wales
Under the Energy Performance of Buildings (England and Wales) Regulations 2012, systems over 12 kW need inspecting at least every five years by an accredited assessor, with the report lodged on the national register. Local Trading Standards enforce it, with a £300 penalty for not having a valid report.
Working hours
Most Harpenden businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Not an F-gas check
A TM44 inspection is about energy efficiency. It does not replace F-gas leak checks or servicing.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
