TL;DR - Oldham SAP in 60 seconds
Design SAP → As-built → EPCDo I need a SAP Calculation?
All new dwellings need a SAP Calculation. Most conversions and some extensions too.
Do I need Part O Assessment?
Yes. Most plots pass using the simplified method. Some, with large glazing or single aspect layout, need Dynamic Simulation.
How long does it take?
Typically 2-4 working days once drawings/specs are in.
What do you need from me?
Plans + site orientation + spec (windows/heating/build-ups).
Will Building Control accept it?
Yes, Elmhurst accredited OCDEA, Part L compliant reports.
What if it fails?
This is common on the first pass. We'll provide the quickest fixes.

*Typical once plans/spec are received. Complex plots may take longer.
Quick Oldham Check: SAP (Part L) and Overheating Calculations (Part O)
SAP (Part L) is the energy compliance calculation for dwellings. It's mandatory for all new homes in Oldham. Many conversions and some extensions need it too.
Overheating (Part O) is a separate assessment. All new dwellings need an overheating assessment. There are two routes to compliance. Most dwellings pass the simplified method, whilst some higher risk projects need a Dynamic Simulation Model (DSM) to demonstrate compliance.
New dwellings typically need both SAP (Part L) and a Part O overheating assessment. Conversions and extensions are assessed differently, we'll confirm what applies once we've reviewed your plans.
SAP Calculations for Oldham Building Control (New Builds, Conversions & Extensions)
SAP calculations are required for new dwellings in Oldham. Most conversions and some extensions need SAP too. They demonstrate compliance with Part L of the Building Regulations and are submitted to Building Control at both design and completion stages.
If you're building in Oldham, whether it's a town centre apartment conversion, suburban infill development, or a new build project anywhere across the borough, Building Control will want SAP Calculations that demonstrate Part L compliance.
We produce the BREL reports your Building Control officer / 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). SAP is the government method for calculating predicted energy use and emissions for dwellings.
Practically: you send drawings + 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 Oldham 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 help 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 within it 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 can lodge the EPC. We'll tell you exactly what evidence is needed.
How the Process Works
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 on Oldham jobs.
We Model SAP 10
We model your dwelling in SAP 10 and check the 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 can turn the as-built assessment into the EPC once evidence is in place.

What We Need to Start Your Oldham SAP Calculation
- Plans: floor plans, elevations, sections
- Site plan: orientation / north point (critical for solar gains and Part O)
- Fabric build-ups: wall / floor / roof construction details and insulation thickness
- Openings: window/door sizes + U-values (a schedule is perfect)
- Heating & hot water: system type, controls, cylinder details (if applicable)
- Ventilation: extract fans / MVHR / MEV details (if known)
Frequently Asked Questions From Clients in Oldham
How long does a SAP calculation take in Oldham?
Most SAP calculations for projects in Oldham are completed within one to two working days once we receive your drawings. Larger or more complex developments may take a little longer, but we always confirm the expected turnaround before starting.
Do Oldham projects need a Part O assessment as well?
All new build homes in Oldham now require a Part O Overheating Assessment. Most pass using a simplified method, but some, particularly where designs include large areas of glazing, single aspect layouts or reduced ventilation, need Dynamic Simulation to model the overheating. We regularly advise on Part O requirements for Oldham and Greater Manchester projects and can confirm what applies once we review your plans.
What happens if my SAP calculation fails?
A fail result on first submission is common, especially on new builds and extensions in Oldham where glazing levels or fabric performance are tight. We provide clear, practical recommendations to bring the design into compliance, such as insulation upgrades or specification changes. All reasonable revisions are included.
Can you help make my design pass Building Control?
Yes. We work closely with builders, architects and homeowners across Oldham to guide designs through Part L compliance. We explain which changes have the biggest impact so you can make cost-effective decisions without unnecessary upgrades.
Do you provide the EPC as well?
Yes. The Energy Performance Certificate (EPC) is produced at the As-Built stage. For Oldham projects, we can complete the As-Built SAP and lodge the EPC once construction is finished. This can be added as an upgrade when you are ready.
What information do you need for an Oldham SAP calculation?
We typically need floor plans, elevations, sections, a site plan showing orientation, construction details, heating and hot water specifications, and a window schedule. All documents can be uploaded through our client portal for Oldham and Greater Manchester projects.
Will Oldham Building Control accept your SAP reports?
Yes. All SAP reports are completed by an Elmhurst accredited OCDEA and meet Part L requirements. Our reports are accepted by Oldham Council Building Control and private Building Control bodies throughout Greater Manchester and the wider UK.
