Glasgow - SAP Extension Calculations / SAP Extension Assessment

These are a Government defined process in accordance with Part L1B Building Control Regulation Compliance of Domestic Property SAP Extension Calculations are the Government's Standard Assessment Procedure for Energy Rating of Dwellings.

Since 6th April 2006, Part L1B has required SAP Extension Calculations to be carried out on every new conversion.

You will automatically achieve Compliance with Part L1B if the extension envelope is sufficiently insulated, the area of all openings is within the 25% allowance and building service are sufficient.

All SAP Extension Calculations are calculated in accordance with Part L1B of the building regulations.

By upgrading or over compensating in construction of other elements, or perhaps demonstrating additional solar gains, the negative impact of larger expanses of glass can be removed.

There are further options to upgrade the existing property - especially useful if the existing dwelling is receiving a make-over too. We can guide you through all the options.

Many change of use schemes will also be subject to SAP regulations, like flat conversions or commercial-to-residential conversions

Many extension designs do not comply with the minimum Part L1b regulations.
