The Standard Assessment Procedure (“SAP”) is the Government’s approved methodology for calculating the energy performance of dwellings.

Do I need a SAP assessment?

If you have built or are planning to build a new dwelling, then Approved Document L1A of the Building Regulations states that you must obtain a SAP rating for that dwelling.

If you renovate a building which results in a material change in use, then we can undertake a SAP assessment to demonstrate compliance with Approved Document L1B.

How long does a SAP assessment take?

We aim to complete each SAP assessment within five working days from the point of engagement.

How much does a SAP assessment cost?

We strive to ensure each quote is the most competitive in the market, offering you real value for a quality service. Factors that will affect the cost of a SAP assessment include the size and complexity of the dwelling. Call now for an instant quote from one of our experienced SAP assessors.
