SAP Assessments (OCDEA)
SAP = Standard Assessment Procedure
Why choose Fire & Environmental Property Services Ltd to conduct your SAP assessments?
We offer you an efficient and reliable service at competitive prices. Our goal is to provide you with a compliant SAP test that can be signed off and handed to building control.
We will give you consultation on any issues that may arise if your design fails to meet compliance, and we will endeavour to work with you to find cost effective solutions, these may be regarding the following: Insulation, heating system, building fabric, glazing and more, some issues may require some material alternatives to make U Values achieve the targeted values as stated within building regulations.
We can calculate U Values and generate the reports for them without the need for a full SAP assessment depending on your needs and the type of project you need them for.
New builds
Providing design stage and as built assessments, every new residential property is required to have individual SAP assessments to demonstrate that the property meets the energy efficiency targets set out in building regs part L.
Conversions
Required when a building is converted, this can be a barn conversion, converting one property into multiple i.e. one three storey house being converted into three separate flats, a commercial premises being converted to residential or multiple houses converting to one to name a few.
Extensions
Required when the proposed windows and doors are more than 25% of the extensions floor area & open plan designs. Some local authorities might require a SAP for an extension even if the windows and doors are less than 25% of the extensions floor area to demonstrate that the extension meets building regulations.
U-values
Custom U-values are generated to measure the rate of heat loss through a building element such as, external walls, roofs and floors. These can be altered during the design stage to improve energy efficiency targets.
Improvements where necessary
It is important that SAP assessments are conducted early in the design stage for both new builds and conversions, this is to ensure that any improvements can be made prior to commencing construction.
BREL Compliance Report
A BREL (Building Regulations England Part L) compliance report is a two-part document that verifies a new home's energy efficiency against the Part L targets. The design stage BREL is created before construction, outlining the expected performance, while the as-built BREL is completed after construction, using the actual materials and installations to confirm that the finished home still meets the required energy standards.
Information required to conduct a SAP assessment
It is important that the information and documents provided are as accurate and detailed as possible, this is to ensure we produce an accurate assessment and also provides evidence in the event of an audit. Extra documents may be required upon completion of the project to prove that the products used are as stated in specifications and consultations, and to prove to potential auditors that the property has been constructed as specified in accordance with the SAP assessment.
