In short
An energy performance certificate, or EPC, rates a building's energy efficiency from A to G and includes recommendations for improvement. A valid EPC is generally needed when a property is marketed for sale or letting, subject to the applicable exemptions. Peachtree Maintenance coordinates assessments and helps landlords, agents and property managers understand the paperwork and any next steps before marketing or improvement work.
Validity and minimum rental standards
Frequency: Valid for 10 years
An EPC is normally valid for ten years unless replaced by a newer certificate. For buildings requiring one, arrange a valid EPC before marketing for let or sale and make it available to prospective tenants or buyers as required. Marketing material must include the energy rating where applicable. Check the official register before commissioning another certificate, as an existing valid EPC may be usable.
Minimum Energy Efficiency Standards generally require privately rented domestic properties in England and Wales within scope to have an EPC rating of E or above, unless a valid exemption applies and is registered on the PRS Exemptions Register. The rules cover continuing lettings as well as granting new tenancies. An F or G rating should prompt a review before letting continues or a new tenancy is agreed.
Government proposals seek to raise rental energy efficiency standards. Do not treat a proposed future rating or implementation date as settled law without checking current GOV.UK guidance. Domestic and commercial rules differ, and Scotland has a separate framework. Local council guidance can help clarify enforcement and property-specific questions, particularly where exemptions or unusual buildings are involved.
What an EPC assessment involves
For an existing home, the assessor records relevant features such as construction, insulation, windows, heating, controls and hot water provision. The rating uses a standard assessment method, not the current tenant's actual bills or thermostat preferences. Two households in the same property may therefore spend different amounts even though the EPC rating is unchanged.
Provide reliable evidence for improvements that cannot easily be seen, such as insulation installation documents or suitable building records. The assessor must follow evidence rules and cannot simply accept an unsupported description. Access to the loft, heating equipment and relevant rooms may help avoid assumptions where features cannot otherwise be established.
Using recommendations sensibly
An EPC recommendation report is a starting point, not a detailed building specification or a guarantee of savings. Consider the property's construction, ventilation, moisture risks and any planning, freeholder or listed building restrictions before commissioning work. A measure that improves the modelled rating may still need specialist design or consent to be suitable for the building.
Where a home falls below E, review applicable improvement requirements and any legitimate exemption route using current guidance. Exemptions are not automatic: supporting evidence, registration and expiry dates matter. Listed status does not create a blanket exemption from EPC or rental standards. Peachtree can coordinate agreed maintenance and refurbishment work, while the assessor determines the resulting rating.
How it works
- 01
Check the existing record
Share the address, intended sale or letting and any previous certificate. We check whether an assessment is needed and flag questions about the building's use or scope.
- 02
Prepare the evidence
Gather relevant insulation, heating and improvement documents. Agree access to rooms, the loft and equipment, and tell us about any restrictions before the assessment.
- 03
Complete the assessment
The accredited assessor records the building features and prepares the certificate using the required method. Findings are based on the assessment and accepted evidence, not a promised target.
- 04
Review the next steps
Receive the digital certificate and review the rating before marketing or letting decisions. If improvements or exemption checks are needed, agree those separately and retain the supporting records.
Frequently asked questions
01Do I need a new EPC every time the tenant changes?
Usually not if the existing certificate is still valid and suitable for the property. Check its expiry and whether a newer certificate has superseded it. Separately confirm the property meets applicable minimum rental standards, because having an EPC does not by itself make a letting compliant.
02Can I rent out a property with an EPC rating of F or G?
For domestic private rentals within the England and Wales rules, a rating below E generally prevents letting unless a valid exemption applies and is registered. Do not assume that an old tenancy or planned future work is sufficient. Review current guidance and obtain appropriate advice on the property's position.
03Is an EPC required for every individual room in an HMO?
Not necessarily. Requirements depend on whether the transaction concerns the whole building or an individual room and whether the accommodation forms a self-contained unit. HMO status alone does not settle the question. Check the letting arrangement and current guidance before deciding that no certificate is needed.
04Will replacing the boiler guarantee a better EPC rating?
No particular rating can be guaranteed from one measure alone. The assessment considers the property as a whole, including its fabric, heating and controls. Discuss proposed improvements with an assessor and suitable contractors before spending money solely to reach a target rating.
05Does the EPC show what my tenants will actually pay for energy?
No. Its estimated costs and recommendations use standard assumptions, so they are not a quote for household bills. Occupancy, weather, tariffs and how the home is heated all affect actual spending. Use the rating to compare assessed performance, not to promise tenants a particular bill.
