If you are selling, renting, or letting a property in 2026, understanding the Domestic Energy Performance Certificate (EPC) process is essential. EPCs are legally required in the UK, and knowing how long an assessment takes and what to expect ensures a smooth, stress-free experience.

This guide explains the timeline, inspection process, fees, and homeowner responsibilities for a Domestic EPC in 2026.

What Is a Domestic EPC?

A Domestic EPC assesses the energy efficiency and environmental impact of residential properties. It assigns a rating from A (most efficient) to G (least efficient) and provides recommendations to improve energy performance.

Homeowners need an EPC for:

  • Selling a property

  • Renting or letting a home

  • Planning energy efficiency improvements

Professional Domestic EPC services can be booked via EPCrate Domestic EPC Services.

How Long Does a Domestic EPC Take in 2026?

The time required for a Domestic EPC depends on property size, complexity, and accessibility:

  • Small properties (1–2 bedrooms): 45–60 minutes

  • Medium properties (3–4 bedrooms): 1–1.5 hours

  • Large properties (5+ bedrooms): 1.5–2 hours

Additional time may be needed for:

  • Complex heating or renewable energy systems

  • Listed or historic properties requiring special consideration

  • Homes with multiple extensions or unusual layouts

After the inspection, the assessor calculates energy ratings and issues the certificate digitally, typically within 1–3 working days.

What Happens During a Domestic EPC Assessment?

A certified EPC assessor will follow a step-by-step process:

1. Inspection of the Property

  • Check the building fabric, including walls, floors, roofs, and windows.

  • Assess insulation, draught-proofing, and glazing.

  • Review heating and hot water systems, including boilers and radiators.

2. Review of Energy Usage

  • Analyze energy bills and consumption patterns.

  • Note any renewable energy sources, such as solar panels or heat pumps.

3. Measurement and Data Collection

  • Measure floor areas and room dimensions.

  • Record system specifications and operational details.

4. Certificate Generation

  • The assessor calculates the energy efficiency rating and environmental impact.

  • Recommendations for improvements, such as insulation upgrades or lighting replacements, are provided.

  • The certificate is lodged digitally in the EPC register and is valid for 10 years.

Factors That Can Affect EPC Duration

  5. Renewable or Complex Systems – Solar panels, heat pumps, or smart home systems require extra recording time.

Tips to Make the EPC Process Faster

  • Prepare Documentation – Have floor plans, energy bills, and system manuals ready.

  • Clear Access – Ensure unobstructed access to all rooms, lofts, and plant areas.

  • Inform Tenants – Notify occupants to avoid delays during inspection.

  • Maintain Systems – Make sure heating and lighting systems are working properly.

Proper preparation can reduce inspection time and may even improve your rating.
