SAP Calculations in London
Working in London and the South East
From Croydon to Kingston upon Thames, we provide SAP Calculations on sites throughout London and the South East (E, EC, N, NW, SE, SW, W and WC, plus outer London), for everyone from self-builders to multi-plot developers. SAP Calculations is one of the services London clients book with us most often.
London boroughs often set energy and carbon targets through the London Plan and local policy, so planning conditions on London schemes frequently ask for energy information alongside your Part L calculations. We can line those up at the same time.

Building in London
The London development market
London projects are dominated by flats: conversions of houses and commercial buildings, infill and backland sites, and mid-rise blocks. Tight sites, party walls, overheating risk and London Plan energy policies all shape what is needed, and boroughs set their own planning conditions, so the paperwork varies from one borough to the next.
Typical London projects we support
- House-to-flat conversions
- Commercial-to-residential conversions above shops
- Backland and infill sites
- Mid-rise apartment blocks and roof extensions
Councils we work across
We handle SAP Calculations for sites in the 32 London boroughs, the City of London Corporation and nearby Hertfordshire, Essex, Kent and Surrey councils, and coordinate with whichever planning and Building Control body covers your site.
