SAP Calculations for Liverpool Building Control
SAP (Standard Assessment Procedure) calculations are required for all new dwellings in Liverpool. Most conversions and some extensions need them too. They demonstrate compliance with Part L of the Building Regulations and are submitted to Building Control at both design and completion stages.
Whether you're building in Liverpool centre, the suburbs or anywhere across Merseyside, Building Control will want SAP Calculations that demonstrate Part L compliance. We produce the BREL reports your Building Control officer or approved inspector expects: a Design SAP for the plans stage, and an As-Built SAP at completion (which is used to generate the EPC and compliance report).
Practically: you send drawings and spec, we model it in SAP 10, then we tell you the quickest route to pass without "gold plating" the build — usually a handful of targeted tweaks.
Typical Liverpool Projects We Help With
New Build Homes
Infill plots, replacement dwellings and small to medium developments. We model realistic specifications and update the model throughout the build to avoid late-stage fails.
Extensions with High Glazing
Extensions with large doors or roof glazing often need SAP checks. We balance fabric performance to meet Part L, using one of the three methods available for extension compliance.
Conversions & Change of Use
Any building where the number of dwellings changes needs a Conversion SAP. We advise on insulation, ventilation and heating choices that keep compliance achievable.
As-Built SAP & EPC
When the build is complete, we finalise the as-built SAP and lodge the EPC. We tell you exactly what evidence is needed.
How the Process Works
-
1
Send Your Drawings
Upload plans, elevations, sections, and a site plan showing orientation. If you have a window schedule, include it — it's one of the most common missing bits we see.
-
2
We Model SAP 10
We model your dwelling in SAP 10 and check Part L targets. If it's tight, you get a short list of practical tweaks ranked by impact — so you're not guessing what to change.

Reports for Building Control
You receive the outputs Building Control expects, including the compliance report. At completion we turn the as-built assessment into the EPC once evidence is in place.

Frequently Asked Questions From Clients in Liverpool
How long does a SAP calculation take in Liverpool?
Most SAP calculations for projects in Liverpool are completed quickly once we have your drawings. Larger or more complex developments may take a little longer — we always confirm the expected turnaround before starting.
What happens if my SAP calculation fails?
A fail on first submission is common, especially on new builds and extensions in Liverpool where glazing levels or fabric performance are tight. We provide clear, practical recommendations to bring the design into compliance — usually a small number of targeted changes rather than a full redesign.
Do you cover the whole Merseyside area?
Yes. We work with builders, architects and self-builders across Merseyside and throughout the UK. SAP Calculations are produced from your drawings and spec, so we can support your project wherever you're building.
Will Building Control in Liverpool accept your reports?
Yes. We're an Elmhurst accredited OCDEA practice, producing Part L compliant SAP Calculations, BREL reports and EPCs that Building Control officers and approved inspectors expect to see.
