Stephen Martin
The assessor was very friendly & professional. I would have no hesitation in recommending him and his company. Good value for money and very courteous service from start to finish.
ASL Architects
We have worked with UK EPC Energy Consulting for a number of years and they have added a lot of value to our firm. Their advice offered as design has always been practical and useful.
Roberta Mcgookin
Very professional company to deal with. Alex very responsive and quick to keep us informed along the way. I would highly recommend without hesitation.
Conor McKenna
The surveyor was very professional and friendly. During the assessment he explained everything at each stage. He provided an excellent service and I would happily recommend him to anyone requiring SAP reports for a new home.
Roberta Flynn
Very easy process. My husband and I needed the paperwork for building control. We ordered the service online and the assessor contact us on time to get the drawings of the house. He sent the report within a few days.

FAQs
SAP stands for Standard Assessment Procedure. It is the government approved methodology for the energy rating calculation of dwellings.
SAP calculations take about 3-4 working days, provided that we have all the information we need.
As an Energy Agency we cover the entire of the UK. So whether your building project is in England, Wales, Scotland or Northern Ireland we can promptly produce SAP compliance reports based on your local Building Regulations, as long as we have drawings and specifications emailed to us
You will need SAP calculations if you are building a new house. You will also require SAP calculations for any type of conversion or change of use, as well as for an extension or a large glazed area.
Usually, we ask for architect’s drawings. After you order your SAP reports, we will email you a small checklist of the information we need from you in order to carry out the SAP calculations. We will help you through the process so it is simple and quick.
SAP calculations are produced by our team of accredited professionals who are qualified OCDEA’s.
We work from architects’ drawings only. There is no requirement to visit the actual property.
Firstly, we will talk to you, or your architect, in order to receive floor plans, elevations and sections of the project, as well as details of the building’s fabric, heating system, controls, lighting, glazing, wall insulation, loft insulation, etc. Then, we use the latest SAP technology to calculate DER and DFER metrics and all Compliance Documentation.
A Guide To SAP Calculations Requirements
SAP Calculations are important when it comes to assessing the energy efficiency of a new dwelling, a conversion, or a building extension. In practice, we use SAP assessments to estimate the energy performance of a dwelling in terms of its fabric efficiency, heating, cooling, and ventilation requirements. As a homeowner, architect or building contractor, you may require SAP Calculations when you apply for Building Control approval.
In short, a SAP assessment provides an indication of how energy efficient a building is, as well as its carbon impact. Also, SAP Calculations produce the EPC, which gives potential buyers or tenants an estimate of their annual energy costs.
We use SAP, as a methodology, to determine the energy performance of a building. Also, we use SAP to identify areas where improvements can be made. SAP stands for Standard Assessment Procedure. It is essentially the latest regulations related to energy efficiency and the protection of the environment. The system produces compliance reports that one should follow in order to ensure that their building meets the government targets. At design stage improving the energy efficiency of a new build is possible by taking various steps such as re-specifying the fabric of walls, ceiling, and floors; re-specifying windows and doors, lower u-values and implementing renewable energy solutions.
Improving the energy efficiency of a new build home is becoming increasingly important. This is both in terms of meeting the government’s latest regulations and to save money in energy bills the long term. Recently, there are various steps that home owners, or architects, can take to improve the energy performance of a home. As we said, this can be done at design stage. For instance, using energy efficient fabric, reducing open spaces, and reducing glazed areas. Also, improving efficiency of windows and doors and increasing insulation levels. Finally, new regulations require better airtightness of the building, and the consideration of heat pumps and photovoltaic panels.
In simple words, the Target Fabric Energy Efficiency (TFEE) of a home is an important measure that we use to assess the energy efficiency of the chosen building fabric. We calculate it by taking into account the proposed wall, ceiling and floor structures. Also, we factor in the proposed insulation, windows and doors as well as the specified air tightness and ventilation. By understanding TFEE of a new home at design stage, architects and homeowners can make informed decisions about what building solutions to use while they are still at design stage. We also understand how to modify the design in order meet the latest energy efficiency requirements.
Ideally, we must consider TFEE for computer simulation and optimisation at design stage. Once a house is finished it becomes very complicated, if not impossible, to change TFEE values. The TFEE target for new homes has been set by the government and it is important that all new build homes meet this standard in order to ensure compliance. The standards vary between England, Wales, Scotland and Northern Ireland, with 2022 Building Regulations already in force.
