SAP Calculations are a Building Regulation. They are required for all newly built dwellings. The Standard Assessment Procedure forming part L of the England & Wales building regulations is a measure of the energy efficiency of a property. The government introduced the SAP assessment scheme to determine whether a building complies with the regulations.
The building regulations spoken of above are:
- Part L (England and Wales)
- Section 6 (Scotland)
- Part F (Northern Ireland)
At UK Building Compliance, we are able to professionally complete any SAP calculations for you. Our highly trained members of staff are ready to complete the task thoroughly and professionally.
SAP calculations will be required for:
- New builds
- Any existing property being converted into a dwelling (i.e. former office buildings being converted to apartments)
- Extensions to dwellings where the glazing is more than 25% of the floor area being added

Who is Able to Complete a SAP Calculation?
In theory, it is possible to complete a SAP calculation yourself, but this is definitely not advisable. The staff at UK Building Compliance have years of experience in the field and the process is a complex one. Hiring us to ensure that the job is done correctly and within the framework laid down by the government. After all, an incorrect SAP calculation could cost you more money in the future.
What Needs to Be Provided to Complete a SAP Calculation?
We are able to complete a SAP calculation without the need to visit your site, however we must receive some documentation from you. We need to receive:
- A complete set of architectural drawings (floor plans, sections, elevations and site plan).
- An architect’s specification, or if you do not have one a completed data collection sheet.
We have specialist software that allows for the SAP calculations to be completed in a timely manner.
How is a SAP Calculation Worked Out?
Do you want to know how a SAP calculation is worked out? We assess how much money the cost of providing heating, ventilation and lighting to the house will be. We then subtract any energy saving solutions from this total.
In addition, the amount of carbon dioxide (CO2) that will be released from the dwelling is calculated. The dwelling is then allocated a score from A+ to G, with A+ being the best and G being the least energy efficient.
If you do not achieve compliance with the designs/specifications provided, we are able to advise a number of different ways in which you can raise the score. We’ll keep our suggestions as cost effective as possible. We can then repeat the SAP calculation to prove compliance with building regulations.
Why is a SAP Calculation Necessary?
There are TWO reasons why you need to get a SAP calculation completed. One legal and the other moral.
- From a legal point of view, the SAP calculations must be completed in order to satisfy the requirements of building regulations. Aiming to ensure that all dwellings are as environmentally friendly as possible. The government has a target of ensuring that all new homes built after 2016 should be net zero carbon. SAP calculations are also needed to satisfy planning conditions and to conform to the Code for Sustainable Homes.
- A Moral requirement is to ensure that any new or modified dwelling is environmentally friendly. It is important that developers make sure the SAP calculation is good otherwise the buyer will find themselves with massive energy bills to pay. For these reasons, even without the legal obligation, a SAP calculation is vital.
When Should a SAP Calculation Be Completed?
It is a legal requirement that a Design Stage SAP calculation is completed before any construction begins. Many people leave the SAP calculation until the last minute though, which is a bad idea. A SAP calculation needs to be completed as soon as possible. If we find a problem, changes to the plans can be made to ensure that the dwelling SAP is satisfactory.
Leaving the SAP calculation to the last minute it means that they have no time to implement any of the recommendations that we provide. Therefore, we recommend getting a SAP calculation completed well before the commencement of any project, in order to provide some breathing room.
The second stage of the SAP assessment is completed after the dwelling has been constructed, and is known as the As Built DER. This is required, along with the On Construction Energy Performance Certificate (OCEPC), to ensure that the building is signed off.
Does Every New Dwelling Need a SAP Calculation?
A SAP assessment must be completed on all new build properties to gauge the energy efficiency of each one. If a building is part of a large development of the same house type, a SAP calculation can be taken from a sample, and then applied to each building. This will mean that every plot has a SAP calculation attached to it, but that not every plot is actually assessed.
When working on a development of a number of the same house types, we will more than happily adjust our pricing to reflect the reduced workload. We can also carry out other tasks concurrently if needed, to ensure that the properties meet guidelines laid down in other schemes.
Documents can be sent directly through our website or via email, post or dropped into our office.
SAP Assessments and EPCs – What’s the Difference?
A SAP is solely an assessment, whereas an EPC is a certificate. An EPC is produced based on the results of the SAP assessment in order to show the energy use and CO2 emissions from a building. Although there are certain similarities between SAP assessments and EPCs, it is important to remember that they are both completely separate entities. At UK Building Compliance, we are able to produce EPCs as well, so please visit the EPC page or contact us today for more details.

- Domestic EPCs – these must be issued to every new dwelling, or any dwelling about to be sold.
- Commercial EPCs – these must be issued to any commercial building upon completion or when it is being sold.
- Display Energy Certificates – these must be displayed in all public buildings, to show visitors how energy efficient the building is.
- Ventilation Testing – this ensures that a building’s ventilation is efficient and effective.
- U Value Calculations – these show how much heat is lost through different materials used in the construction of a building.
