During this, we will sit down with you and discuss your project requirements and make extensive recommendations on how to best comply with all current L1A and L1B building regulations.

We could potentially save you thousands!

While there are a few SAP calculation providers across Guildford, Essex and the UK that offer cheap calculations that might look easy and quick, they aren't ever optimised for all current building regulations. Typically they then cost the client or building company 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 Essex and Guildford, 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.
