SAP Calculations/New Build EPCs


Bournemouth Energy is an established energy rating company with a reputation for providing a thorough and professional service at highly competitive rates. Using software approved by the Building Research Establishment, Bournemouth Energy’s experienced team can produce an unbiased, well-informed rating both at design stage and again at completion, if changes have occurred.

Bournemouth Energy endeavors, wherever possible, to produce accurate results in the fastest possible turnaround time.

SAP calculations (Standard Assessment Procedure) are required under Building regulations Part L1a and Part L1b to provide a building with an energy efficient model to meet both the building regulations Fabric and carbon emission output target.

The SAP calculation is a way to ensure compliance under  these building regulations and allows for a qualified and accredited assessor to competently give a predicted rating (as design) to ensure this area of building regulations has been satisfactorily met. Once the building work has been completed Bournemouth Energy will then convert the predicted rating to an On Construction EPC which the developer will need to provide to their Building Control officer.

There are many parts to Building Regulations and Bournemouth Energy can ensure all your SAP Calculation requirements are met. In the instance where the building targets are not met after modelling the SAP calculation based on the proposed design and specification, Bournemouth Energy will provide expert advice on the material changes required that will satisfy Building Regulations under Part L1a & L1b. We will always have the most cost efficient measures at the forefront of our recommendations.


Bournemouth Energy provides SAP calculations on New Build dwellings, Conversions and Extensions.
