If your project is to create a new dwelling through a change of use (i.e the conversion of a building to dwelling or even by creating a greater or lesser number of dwellings or other residential units within an existing building) then your Building Regulation application will require a Part L1b SAP Calculation.

 

We will help make Building Regulation compliance easier by offering solutions and guidance throughout the design and/or build process concerning the controlled fittings and building materials necessary to meet the efficiency standards and overcome compliance issues in a cost efficient way.

 

We will save you money by assessing from architect’s drawings the building materials and heating products so there’s no need for costly site visits. We will never fail a conversion project and will always provide cost effective solutions and feedback for achieving as high a pass rate as possible.
