SAP calculations Leicestershire

Leicestershire has eight Local Planning Authorities — Leicester City Council plus Blaby District, Charnwood Borough, Harborough District, Hinckley & Bosworth Borough, Melton Borough, North West Leicestershire District, and Oadby & Wigston Borough. Each operates its own Local Plan, with sub-regional coordination through the Leicester and Leicestershire Strategic Growth Plan. We work with all eight on a regular basis. Build Envelope is OCDEA-accredited (EES/030713) and based in Worcester, delivering remotely across the county.

SAP (Standard Assessment Procedure) is the government-approved method for calculating the energy performance of new build dwellings. It is required at Design Stage to demonstrate compliance with Part L of the Building Regulations, and again at As-Built stage before an EPC can be issued.

Leicestershire carries some of the largest residential allocations in the Midlands — the Lubbesthorpe development in Blaby, sustainable urban extensions around Loughborough and Hinckley, and continued city-centre apartment and student schemes in Leicester. Leicester City and Charnwood set the most prescriptive energy policies in the county, while the rural districts apply their thresholds more selectively. We understand what each Leicestershire LPA expects in submitted documentation.

Whether you are submitting outline planning, reserved matters, or seeking a fully accredited SAP and EPC, we deliver in 3-5 working days. Need it faster? Tell us — we routinely accommodate urgent turnarounds across Leicestershire.

Part L 2021 compliance

DER ≤ TER
Dwelling Emissions Rate must be lower or equal to Target Emissions Rate — Part L 2021, England
Leicestershire Local Plans go beyond Part L baseline. Leicester City and Charnwood both set policy energy targets for major schemes — we model your spec against both Part L and the relevant district policy.
EPC ratings: A (92+), B (81-91), C (69-80). Most Leicestershire new builds need a B or higher; certain LPA conditions require A.

How a SAP calculation runs from drawings to EPC.

SAP is desk-based, so location within Leicestershire makes no difference to delivery. We typically issue Design Stage in 3-5 working days from a complete information pack, with urgent turnarounds available on request.

01
Information pack & quote
Send us your architectural drawings, intended construction U-values, window and door schedule, heating and ventilation strategy, and any planned renewables. We confirm scope and price within one working day.
02
Design Stage modelling
We model each dwelling type in accredited SAP 10 software, comparing the Dwelling Emissions Rate against the Target Emissions Rate. Your spec is checked against Part L 2021 and applicable Leicestershire Local Plan policy.
03
Spec optimisation
If a dwelling fails or is marginal, we model the lowest-cost route to compliance — typically tweaking U-values, glazing, air permeability target, ventilation strategy, or renewables — and feed those back to the design team.
04
As-Built SAP & EPC
Once construction completes and we receive air test results and as-built confirmations, we re-run SAP and lodge the EPC. Full compliance pack issued in the format required by Leicestershire Building Control teams.

What we need from you to start your Leicestershire SAP.

The faster you send us a complete information pack, the faster we deliver. A typical 3-5 day turnaround starts the day we have everything we need — partial packs are still fine, we'll just flag what's missing and assume sensible defaults until you confirm.

If your design team is mid-process, send what you have. SAP works best as an iterative tool: we can run an early model on indicative U-values and a notional heating system, then refine as your specification firms up. That's often quicker than waiting for the perfect pack.

For Leicestershire schemes with planning conditions tied to a specific energy target — common in Leicester City and Charnwood — tell us the condition wording at the start. We model your spec directly against it, so the report you receive is one your case officer can sign off without coming back for clarifications.

SAP information checklist

Architectural drawings Plans, sections and elevations — PDF or DWG. Scaled drawings preferred so we can extract dimensions accurately.
Construction U-values Wall, roof, floor, and party-element build-ups with target U-values. We can calculate U-values from build-ups if needed.
Window & door schedule U-values, g-values, and frame factor where known. Manufacturer datasheets are ideal.
Heating system Boiler, heat pump, or other — including make, model, and efficiency where specified. Hot water cylinder details if applicable.
Ventilation strategy Natural, MEV, or MVHR — and the intended air permeability target.
Renewables PV array size, heat pump details, or any other low-carbon technology proposed for the scheme.

Common questions about SAP calculations in Leicestershire.

Pricing depends on dwelling type, the number of plots, and whether you need Design Stage only or both Design Stage and As-Built EPC.

Larger schemes are quoted on a per-plot basis with volume discounts. There are no additional travel charges — SAP is desk-based and we deliver remotely across all eight Leicestershire planning authorities.

Standard turnaround is 3-5 working days from receipt of a complete information pack. For urgent submissions we routinely accommodate faster delivery — tell us your deadline when you enquire and we will confirm whether we can hit it.

Because SAP is desk-based, location within Leicestershire makes no difference to turnaround. Call us on 01386 365145 if you have a specific date you need to hit.

Leicester City Council and Charnwood Borough Council typically require Design Stage SAP for major residential applications, particularly under their adopted Local Plan energy policies. Both set energy targets that go beyond the Part L 2021 baseline.

Blaby, Harborough, Hinckley & Bosworth, Melton, North West Leicestershire, and Oadby & Wigston operate similar thresholds, with local variation in policy weighting. We tailor each report to the relevant LPA's submission templates and condition wording.

If your initial SAP run shows the Dwelling Emissions Rate exceeding the Target Emissions Rate, we model the lowest-cost spec changes that bring you into compliance. That usually means tweaking U-values, glazing specification, air permeability target, ventilation strategy, or adding renewables.

We work iteratively with you and the design team rather than just flagging the failure — the goal is a compliant scheme, not a list of problems.

Yes. We deliver SAP calculations across all eight Leicestershire planning authorities — Leicester City Council, Blaby District, Charnwood Borough, Harborough District, Hinckley & Bosworth Borough, Melton Borough, North West Leicestershire District, and Oadby & Wigston Borough.

Build Envelope is OCDEA-accredited (EES/030713) and based in Worcester. SAP is desk-based so distance has no impact on delivery time or cost.

Yes. Leicestershire has some of the largest residential allocations in the Midlands, including the Lubbesthorpe development in Blaby and the sustainable urban extensions around Loughborough and Hinckley. We model each dwelling type once, then apply it plot by plot with orientation and exposure variations, and quote on a per-plot basis with volume discounts.

Design Stage and As-Built are programmed against your build sequence, so EPCs are lodged as plots complete rather than piling up into one bottleneck at the end.

Yes. Alongside SAP and EPC we deliver air tightness testing, ventilation flow rate testing, U-value calculations, PSI-value calculations, water usage calculations, overheating assessments, and energy statements.

Coordinating the full Part L pack through one accredited provider avoids the gaps and contradictions that hold up Building Control sign-off — a common pain point on Leicestershire schemes split across multiple consultants.
