Your
energy compliance
Solution
Salvis offers a comprehensive range of energy compliance and certification services, helping building owners, landlords, and developers across the UK meet their regulatory obligations while improving energy performance and reducing carbon emissions.
Our services include Energy Performance Certificates (EPC), Display Energy Certificates (DEC), Streamlined Energy and Carbon Reporting (SECR), and Building Regulations Part L Compliance.
Energy Performance Certificates
Energy Performance Certificates (EPCs) are typically required for the sale, rent or construction of buildings. They were introduced to give prospective buyers or tenants an indication of a building's energy performance. They have since evolved: under the Minimum Energy Efficiency Standard (MEES), it is now unlawful for landlords to let properties with an EPC rating of F or G.
MEES is an opportunity for landlords and tenants to work together to reduce operational costs, improve environmental conditions, cut carbon emissions and increase the value of the asset. Salvis provides a full EPC delivery service: we undertake the building survey, compile the advisory report and lodge the certificate with the accreditation body.
Display Energy Certificates
A Display Energy Certificate (DEC) must be displayed in all public buildings over 250m². It's based on a building's actual energy use, so it's a good way to compare performance against similar buildings.
A DEC highlights where improvements can be made and tracks energy use over time. The poorer the rating, the bigger the opportunity for cost and carbon savings. Salvis keeps your DECs up to date, then designs and implements solutions that improve your building's energy performance year on year.
Energy & Carbon Reporting
Streamlined Energy and Carbon Reporting (SECR) was introduced in April 2019. It requires quoted companies, and large unquoted companies and LLPs, to report their annual energy use and carbon emissions, along with the energy efficiency measures they've taken over the past year.
Salvis can gather the data to calculate your carbon emissions, write the narrative for your report, and advise on cost-effective actions to reduce energy use.
Part L Compliance
Salvis uses accredited dynamic building modelling software to model thermal performance and energy efficiency, and demonstrate compliance with Building Regulations Part L (Approved Document L, Volume 2: buildings other than dwellings).
This is a statutory requirement for new builds, as well as for extensions and major refurbishments of existing buildings. The model assesses:
- Thermal U-values and construction elements
- Building air tightness
- Type and efficiency of heating and domestic hot water systems
- Building ventilation strategy
- Provision of low and zero carbon and renewable technologies
- Type and efficiency of general lighting
Frequently asked questions
How are MEES regulations changing?
MEES is tightening, but in a more targeted way than first proposed. The current minimum standard for commercial lettings in England and Wales is EPC E. Under the government's June 2026 interim response, privately rented non-domestic buildings over 1,000m² will need to reach EPC B, where cost-effective. Buildings under 1,000m² stay at EPC E for now.
When do the new MEES requirements come into force?
The EPC B requirement for larger commercial buildings is expected to apply from 2031. The previously proposed interim target of EPC C by 2027 has been dropped. Secondary legislation and a full government response are still to come, so details on implementation and exemptions may change.
