Domestic, commercial and new build EPCs — issued by an accredited SAP and iSBEM assessor based in Northern Ireland.
An Energy Performance Certificate (EPC) rates a building's energy efficiency on a scale from A (most efficient) to G (least efficient). It is a legal requirement when a property is built, sold or rented.
In Northern Ireland, EPCs are lodged on the NI EPC Register. For new dwellings, a Design Stage SAP calculation is typically required for Building Regulation approval before construction begins, followed by an As-Built EPC on completion.
For non-domestic buildings over 50m², an iSBEM assessment is used instead of SAP to demonstrate compliance with Technical Booklet F2.
For NI Building Regulation approval, most new dwellings require a Design Stage SAP calculation submitted with your planning or Building Control application. An As-Built EPC is then issued on completion. We handle both stages.
Northern Ireland operates under its own SAP edition — SAP 2009 with Conventions v5.0 and Technical Booklet F1 for dwellings. This differs from England and Wales. Local expertise matters.
Required when selling or renting a residential property. We visit the property, gather the required data, and lodge the certificate on the NI EPC Register.
Typical turnaround: 2–3 working days from survey.
Design Stage SAP calculation for Building Control submission, followed by As-Built assessment on completion. Covers SAP 2009 under NI Conventions v5.0, including renewables, PV and heat pump modelling.
We work directly with your architect and Building Control office.
Non-domestic EPC and Building Compliance Report using iSBEM software. Covers extensions, change of use, and new commercial buildings under Technical Booklet F2.
Experience includes hotel, retail and spa facilities across the Causeway Coast area.
Call or email with the property type, address and reason for the EPC (sale, rental, new build, Building Control). We'll confirm the service required and agree a fee.
For existing dwellings, Declan visits the property. For new build SAP, we work from your architect's drawings and specification. For commercial, we gather building fabric and services data.
The SAP or iSBEM calculation is completed and checked. Any compliance issues are flagged before lodgement — giving you the opportunity to address them without delay to your programme.
The EPC is lodged on the NI Register and the certificate forwarded to you, your solicitor or your Building Control office as required.
Domestic EPCs are priced at £85–£120 depending on property size and complexity. New build SAP calculations are priced separately depending on the specification. Commercial EPCs are priced individually — contact us for a quotation based on your building type and floor area.
An EPC is valid for 10 years and can be reused for multiple sales or lettings during that period, provided the property has not been significantly altered.
Yes. An EPC is a legal requirement when marketing a property for sale or rental in Northern Ireland. It must be made available to prospective buyers or tenants at the earliest opportunity.
SAP (Standard Assessment Procedure) is the government-approved method for assessing the energy performance of new dwellings. In Northern Ireland, a Design Stage SAP calculation is required as part of your Building Regulation application under Technical Booklet F1. An As-Built EPC is then issued on completion.
SAP applies to domestic (residential) new build properties. iSBEM (Simplified Building Energy Model) is used for non-domestic buildings — such as commercial premises, extensions to commercial buildings, or change of use. D. Heggarty Surveying is accredited for both.
New build, sale, rental or compliance — we'll confirm what you need and provide a fee straight away.
