SAP Rating

A SAP rating is required for all new builds in the UK, and for many extension and conversion schemes.

We at Build Energy are specialists in SAP and Part L compliance – it’s what we do, day in, day out. We can provide as much support as you need to ensure that your build not only meets the SAP Rating targets but also meets the wider building regulations but also any local planning conditions and energy policy.

SAP Rating

How does it work?

We work with clients to achieve the energy performance targets set within Part L of the building regulations. Your SAP assessor will assess the dwelling from architects drawings and from the construction specification. We also factor in the heating, lighting and ventilation strategy to establish the CO2 emissions and energy costs associated with that dwelling. Because of this ‘off plan’ nature of the assessment we do not need to come to site.

We will never fail a project and will always provide solutions and feedback for achieving a pass.

Ask us for a SAP Rating – it’s our speciality

Build Energy have extensive experience in dealing with Part L1a SAP Ratings and can provide you with all the help and guidance you need. We help hundreds of clients with SAP Ratings every year, from homeowners and architects, to house builders and engineers. Local energy and environmental policies may dictate that you are subject to tighter targets, and so we will work with you to satisfy your particular requirements.

Our unique approach allows us to manage all of the environmental aspects of a build from early concept design through to completion.

This includes advice and guidance around construction, services, heat loss calculations and on-site testing.
