2026 regulation update
From 15 June 2026, new homes in England and Wales must achieve EPC B (92 SAP points, up from 81) under updated Building Regulations. That’s a meaningfully higher bar, and it raises design complexity — expect more design iterations to land on a compliant specification first time. Our design-stage SAP pricing reflects that additional iteration work from mid-2026 onward, so getting us involved early is the most cost-effective route to compliance.
What our clients say
Trusted by landlords, agents and homeowners
"Used their SAP EPC service across a 12-plot development. Communication was excellent throughout, even with the new EPC B target."

SAP EPC (New Build) — common questions
When do I need a design-stage SAP?
Typically submitted alongside your Building Regulations application, before construction begins.
What's an On-Construction EPC?
An EPC produced from the as-built SAP calculation once the property is complete, required before first occupation or sale.
Can you handle multi-plot developments?
Yes, we offer discounted per-plot rates for multi-plot and phased developments, with further savings on repeat house types.
What's changing on 15 June 2026?
New homes in England and Wales will need to achieve EPC B (92 SAP points, up from 81) under updated Building Regulations. This raises design complexity and typically means more design-stage iterations to reach a compliant specification — factor this into your programme and budget.
