SAP stands for Standard Assessment Procedure, a government standard that's been in place since 1994. It was brought into the regulations to ensure that your building meets the criteria set out in Part L.

The SAP will determine your build’s average energy use, and this information will be incorporated into your EPC, Energy Performance Certificate. The SAP Calculation is for residential properties. If your build is non-residential, check out the SBEM page.

The SAP, just as with SBEM, has two stages, the design SAP and the as built SAP. The design SAP Calculation, unsurprisingly, needs to be completed, yes that’s right, at the design stage. The as built SAP Calculation needs to be completed once the build has been completed. When designing your project, it is always best to know what influences the SAP Calculation results. Knowledge is power after all. If you know what affects your results, you can improve them. ATSPACE has completed over 27,000 SAP Calculations, so we're confident in our ability to lead the way!

SAP, or Standard Assessment Procedure, relates to Part L of the Building Regulations. The government introduced it to calculate a building's energy and environmental performance. The SAP will also allow for easy comparison of similar style builds across the board. So, you can tell how eco-friendly your build will actually be. Your SAP will help determine the EPC Rating (Energy Performance Certificate) for your property.

A SAP Calculation is mandatory for all new builds, conversions and over glazed extensions.

There are two stages to SAP calculations: the first is completed at the design stage, and the second is completed at the as built stage. Work with ATSPACE at the earliest possible stage, and you can benefit from our wealth of knowledge!

ATSPACE has been established for over 10 years. I am fully qualified in SAP Calculations, and I have trained my enthusiastic Relationship Managers to be there for you, and with you, throughout the whole process.

SAP Calculations - Questions Answered

Ultimate Guide To Passing Your SAP Calculations

This video will give you the top tips to passing your SAP calculations!

How Do I Achieve An A Rating On My SAP Calculations?

When trying to achieve an efficient EPC rating of A, you should first look at the fabric of the build. It's all well and good having renewable technology installed on a property, but that's not going to reduce the energy requirement. So, how can you achieve an A rating?

Can A SAP Assessor Help Reduce Our Costs?

Materials have increased in price over the past couple of years and it's not just timber, we are looking at all construction materials such as your brickwork, your blockwork, your insulative materials especially and also, the mechanical services within the property. But can your SAP Assessor help to reduce costs?
