Dartford's SAP Calculation Specialists

Accurate, reliable and fast SAP calculations, provided across Dartford and Kent.

If you're building a brand new commercial or domestic property, or even a specialist passivhaus dwelling, in Dartford or Kent, it is incredibly important that you have reliable and accurate SAP calculations undertaken to ensure that you meet all current UK building regulations, including Part L.

At Tophouse Assessments Ltd, we specialise in providing fast, cost effective and trusted SAP calculations based around each Dartford client's individual needs and requirements and the specifications of the building project itself. Call us today on 01634 799115 for free and honest advice and a no obligation quotation at your convenience. 

A wide range of build projects covered

Working across Kent, including Dartford, we provide architects, building companies, property designers and private clients with the most accurate and highest quality SAP calculations for a wide range of building projects, including:

  • Property extensions
  • Refurbishments
  • Loft conversions
  • New build properties
  • Highly glazed extensions

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

After your call to us, we will provide you with a free and no obligation quotation. During this, we will discuss your project requirements and make comprehensive recommendations on how to best comply with all current L1A and L1B building regulations. It's never easy to fully comply with Part L of the building regulations at the best of times, but we are here to make sure that you're best placed to do so. 

We could potentially save you thousands!

While there are a few SAP calculation providers across the UK that offer cheap calculations that might look quick and easy, they aren't ever 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 Dartford and Kent, 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.
