Overheating Assessment across Bristol and the South West

From Bath to Nailsea, we provide Overheating Assessment on sites throughout Bristol and the South West (BS), for everyone from self-builders to multi-plot developers. Clients in Bristol regularly add Overheating Assessment to their Building Control and warranty bookings.

Bristol sits in the "moderate risk" category under Approved Document O, so the simplified method often works for houses and well-ventilated flats. Single-aspect or heavily glazed designs may still need TM59 modelling.
