Frequently Asked Questions

Quick answers to the questions we hear most from homeowners, developers and architects across the UK.

What areas of the UK does Energaia cover?

Energaia is based in Derby but works with clients right across the UK. Whether your project is in the Midlands, London or further afield, we can carry out desktop assessments remotely and arrange on-site testing (such as air permeability or extract fan flow testing) wherever your project is located. See our full services or get in touch for a quote.

Do I need an EPC to sell or rent a property?

Yes. UK law requires a valid Energy Performance Certificate (EPC) before a residential or commercial property can be marketed for sale or rent. An EPC rates the energy efficiency of the building and is valid for 10 years. Learn more about our EPC assessment service.

What's the difference between a SAP and an SBEM calculation?

SAP (Standard Assessment Procedure) calculations apply to domestic buildings — new homes, extensions and conversions — while SBEM (Simplified Building Energy Model) calculations apply to non-domestic and commercial buildings. Both demonstrate compliance with Part L of the Building Regulations. See our Services page for a full breakdown of each.

How long does it take to get an EPC or SAP calculation back?

Turnaround depends on the project size and stage, but most desktop assessments (SAP, SBEM, EPC) are completed within a few working days of receiving your plans. On-site testing, such as air permeability, is usually scheduled within a week of enquiry. For an accurate estimate on your project, contact us with your requirements.

Can Energaia support my project from the design stage through to completion?

Yes. Many of our clients bring us in at design stage so we can flag compliance issues early — before they become costly changes on site. We then stay involved through to as-built testing and final certification. Read more about how we work.
