A wide range of build projects covered

We provide private clients, architects, designers and building companies from across Croydon and London with the very best and most accurate SAP calculations for a range of building projects, including:

  • Refurbishments
  • New build properties
  • Property extensions

  • Highly glazed extensions

If you're working on a building project, you need SAP Calculations

We'll provide you with a free consultation; during which, we'll discuss your project requirements and make comprehensive recommendations on how to best comply with all current building L1A and L1B regulations. It's not easy to comply with Part L of the building regulations at the best of times, but we're here to make sure that you do. 

We could save you thousands!

There are many SAP calculation providers across the UK that offer cheap calculations that might be quick and easy but aren't optimised for all current building regulations. Typically they then cost the building company or client thousands of pounds in unneeded expenditure on;

  • MHVR systems
  • Solar panels
  • Unrealistic air test targets
  • Log burning fires
  • Extra insulation

Based just outside London, we work throughout Croydon and the South East, specialising in the provision of reliable, proven and high quality SAP calculations to assist building companies, architects, designers and private clients in meeting all current building regulations.
