Frequently Asked Questions

 An Energy Performance Certificate (EPC) is a legally required document that shows how energy‑efficient a property is. It gives the building an energy rating from A (most efficient) to G (least efficient) and includes recommendations for improving energy performance.
EPCs are used by buyers/sellers, tenants, landlords, and estate agents to understand a property’s running costs and environmental impact.

 In the UK, it is a legal requirement to have a valid EPC before marketing a property for sale or rent.
Government regulations state that:

• Sellers must provide an EPC to potential buyers
• Landlords must provide an EPC to new tenants
• Estate agents and letting agents cannot advertise a property without one

Landlords must also comply with Minimum Energy Efficiency Standards, which require most rental properties to have an EPC rating of E or above.

 EPC prices vary depending on property size, location, and complexity. Clarke EPC offers transparent, fixed pricing with no hidden fees.   

The price includes:

• Full Domestic Energy Assessment
• EPC production
• Lodgement on the official EPC government register

 Most Domestic Energy Assessments take 45–90 minutes.
Larger or more complex homes may take slightly longer.
Your assessor will always work efficiently and respectfully while on your property.

 During the assessment, Clarke EPC will:

• Inspect the heating system and controls
• Check insulation levels (loft, walls, hot water cylinder)
• Measure rooms, windows, and doors
• Record construction details
• Assess lighting and ventilation
• Take photographs & Floor measurements  (required for EPC evidence)

The inspection is non‑intrusive — no drilling, lifting floorboards, or damaging materials.

 You don’t need to prepare much, but the following helps:

• Boiler manuals or installation certificates
• Loft & Cavity insulation certificates
• Details of recent improvements (e.g., new windows, solar panels)
• Access to all rooms, including the loft

Providing documentation can improve the accuracy of your EPC rating.

 An EPC is valid for 10 years.
However, if you’ve made significant improvements — such as insulation upgrades, a new boiler, or renewable energy installations — you may want to update your EPC to reflect the improved rating.

Clarke EPC typically delivers EPCs within 24hours of the assessment.
Typical turnaround times:

• Lodging the EPC: Usually done the same day as the assessment

• Receiving your EPC: Most customers receive their EPC within 24 hours

• Urgent / same‑day EPCs: Often possible depending on appointment time and workload

Once lodged, your EPC is immediately available on the official government EPC register, and you will receive a digital copy by email.

Why it’s so fast

The assessor uploads the property data, photographs, and evidence to the government‑approved EPC register. Once submitted, the certificate is generated automatically and becomes instantly accessible.

What can delay an EPC?

Delays are rare, but can happen if:

• Evidence is missing (e.g., insulation certificates)

• Access to parts of the property was restricted

• The EPC register is temporarily busy or undergoing maintenance

Even in these cases, Clarke EPC aims to deliver your certificate as quickly as possible
