What are SAP calculations and when are they required?

SAP calculations assess the predicted energy performance of a dwelling. They are commonly required for new-build homes, conversions and certain extensions to demonstrate Part L compliance.

What is needed for an on-construction EPC?

The final SAP or SBEM model must reflect the completed building, supported by confirmed construction specifications, test results and commissioning evidence.

What does an Energy Statement include?

An Energy Statement normally describes planning policy, the proposed energy strategy, demand-reduction measures, low-carbon systems, renewable energy and the resulting carbon improvement.

Belfast-based energy assessment support

EnergyWise Services is based in Belfast and supports homeowners, architects, developers, contractors and property teams throughout Northern Ireland. Local delivery is available for EPC surveys and site-dependent work, while drawings-based SAP, SBEM and reporting services can be coordinated remotely from design stage through completion.

SAP and EPC services for Northern Ireland homes

We provide design-stage and as-built SAP calculations for new dwellings, conversions and relevant residential projects, together with on-construction EPCs at completion. For existing homes, we can confirm the appropriate domestic EPC route and the information or site access needed before work begins.

Commercial EPC and SBEM assessments

Non-domestic support includes SBEM calculations for new buildings and regulated fit-outs, commercial EPCs and practical advice where a proposed specification does not meet the required target. Offices, shops, warehouses, hospitality and mixed-use projects can be assessed according to their actual construction and building services.

Joined-up compliance advice

SAP and SBEM work can be coordinated with U-value and condensation-risk calculations, overheating review, water-efficiency calculations, air-permeability testing, ventilation commissioning and Energy Statements. This keeps assumptions consistent and gives the design team one clear list of outstanding evidence.

COMMON QUESTIONS

Clear answers.
No guesswork.

01Do you cover all of Northern Ireland?+

Yes. We support projects throughout Belfast and across Northern Ireland. The need for a site visit depends on the assessment type; many design calculations and reports can be completed remotely from drawings and specifications.

02Do Northern Ireland requirements differ from England?+

Yes. Building Regulations and supporting guidance differ between UK jurisdictions. We confirm the project location and apply the relevant Northern Ireland requirements rather than relying on England-only wording.

03Can you provide both SAP calculations and the final EPC?+

Yes, for a new or converted dwelling we can take the assessment from design-stage SAP through the as-built calculation and on-construction EPC, subject to receiving the required final evidence.

04Can you help with a failing SAP or SBEM model?+

Yes. We identify the inputs driving the failure, test practical specification changes and explain the most proportionate route towards compliance.
