Get StartedSAP Calculations
SAP (Standard Assessment Procedure) Calculations are an essential part of demonstrating compliance with Building Regulations Part L for new residential developments. London Property Reports provides accurate SAP Calculations throughout Greater London, supporting architects, developers, builders and homeowners from design through to project completion.
Our experienced assessors work closely with clients to produce Predicted Energy Assessments (PEA), Design Stage SAP Calculations, As-Built SAP Calculations and final Energy Performance Certificates (EPCs). Every assessment considers insulation performance, heating systems, renewable technologies, ventilation, glazing, lighting and overall building fabric to calculate the property's predicted energy efficiency and carbon emissions.
By engaging with our team early in the design process, clients can identify cost-effective improvements that enhance compliance while avoiding expensive redesigns later in the project. We provide practical guidance throughout the assessment process and work collaboratively with architects and construction teams to ensure projects progress smoothly.
Whether you are constructing a single dwelling, multiple residential units or converting an existing property, London Property Reports offers accurate SAP Calculations, responsive technical support and dependable turnaround times across Greater London.

Frequently Asked Questions

WHO REQUIRES AN EPC?
As of the 21st May 2010, if you decide to place your property on the market for sale or rent in the UK you will need to purchase an EPC. This includes both residential and commercial properties. Since April 2018 it is also a legal requirement for the EPC rating to be a minimium of an 'E' rating in order for that property to be let to a tenant.
Who is responsible for obtaining an EPC?
When you are selling or renting your property, you, as the seller or landlord must provide the EPC. The certificate should be given to the prospective buyer or tenant prior to entering into a sale or lease agreement.
With a new build it is the responsibility of the person carrying out the work. They must provide the owner with the certificate and inform the Building Control Officer or Approved Inspector that this has been completed within the specified time.
The owner/ landlord will have to pay for this survey and we offer extremely competitive prices.
The survey is designed to be a non-invasive visual inspection and all information is to be gathered whilst on site. If there are any measures that cannot be seen i.e. cavity wall insulation, we will require the associated documentation to include this within our certificate.
