All assessments are carried out by accredited professionals and delivered with clear, practical reporting.
Domestic EPCs
Domestic EPCs
An Energy Performance Certificate is a legal requirement when selling or letting a residential property. Our domestic EPC assessments cover houses, flats, HMOs, rental properties, new tenancies, Airbnb and short-let properties, and portfolio landlords.
The certificate rates the energy efficiency of the property from A to G and includes recommendations for improvement. Valid for 10 years.
Ideal for: homeowners selling a property, landlords letting to new tenants, and portfolio managers requiring multiple assessments.
Commercial EPCs
Commercial EPCs
Required for the sale, let or construction of commercial buildings. Our assessors cover offices, retail units, shops, warehouses, industrial units, restaurants, hospitality premises, commercial investments and mixed-use buildings.
Ideal for: commercial property owners, investors, estate agents and businesses managing commercial premises.
Public Display Energy Certificates (DEC)
Public Display Energy Certificates
DECs measure the actual operational energy performance of public buildings using real consumption data — not theoretical calculations. Required for public buildings over 250m² that are frequently visited by the public.
Includes: site assessment and energy data review · certificate production and registration · advisory reports · compliance support · recommendations for improved performance.
Ideal for: schools, hospitals, local authorities, and public sector building operators.
TM54 Operational Energy Modelling
TM54 Operational Energy Modelling
TM54 assessments predict how a building will actually perform once occupied, providing more realistic energy forecasts than standard compliance calculations.
Includes: design-stage energy reviews · operational performance modelling · carbon reduction planning · net-zero strategies · sustainability reporting.
Ideal for: developers, architects, and sustainability teams working on new build or major refurbishment projects.
One Click LCA
One Click LCA
Using the industry-leading One Click LCA platform, we help clients understand, measure and reduce the embodied carbon and whole-life environmental impact of their buildings.
Includes: whole-life carbon assessments · embodied carbon calculations · sustainability benchmarking · ESG reporting support · carbon reduction strategies.
Ideal for: developers, architects, ESG teams, and organisations with net-zero commitments.
Energy Audits
Energy Audits
A detailed examination of how a building consumes energy, identifying practical opportunities to reduce waste and improve efficiency.
Includes: energy consumption analysis · review of building systems · identification of inefficiencies · cost-saving opportunities · carbon reduction recommendations.
Ideal for: building owners, facilities managers, and businesses looking to reduce operational costs and carbon emissions.
ESOS Compliance
ESOS Compliance
We provide complete support for organisations required to comply with the Energy Savings Opportunity Scheme the UK government's mandatory energy assessment programme for large businesses.
Includes: energy data analysis · site inspections · identification of energy-saving opportunities · ESOS reporting · compliance guidance.
Ideal for: large UK businesses and organisations that meet the ESOS qualification criteria.
Do you need this by law?
Some energy services are a legal requirement. Others are a strategic choice. Here is a quick guide.
Required by law
- Domestic EPC — required when selling or letting a residential property
- Commercial EPC — required for sale, let or construction of commercial buildings
- DEC — required for public buildings over 250m² frequently visited by the public
- ESOS — required for large UK businesses meeting the qualification criteria
Good practice & strategy
- TM54 — voluntary but increasingly required by planning authorities
- One Click LCA — voluntary, supports ESG reporting and net-zero commitments
- Energy Audits — voluntary, recommended to reduce costs and carbon emissions
The value of getting it right
Energy assessments are not just a compliance exercise: they deliver measurable results.
