Assessment cost intent

Energy performance certificate cost.

Understand what affects EPC assessment cost, why there is no single official price and what to confirm before appointing an assessor.

Direct answer

How much does an Energy Performance Certificate cost?

There is no single government-set EPC assessment price. GOV.UK states that the cost varies by assessor and property size, while commercial EPC cost depends on the building being assessed. Get a scope and price from an appropriately accredited assessor for the correct property type.

Property type and size

A home and a complex business property do not have the same survey scope or assessor requirements.

Assessor and location

Assessment fees are agreed with the assessor. Check accreditation and what the quoted service includes.

Existing certificate

Search the official register first. The property may already have a certificate suitable for the immediate task.

Step-by-step

What should an EPC quote include?

Confirm the assessment scope before comparing prices. A cheap quote is not useful if it covers the wrong building type or excludes necessary access and evidence.

  1. 1

    Check the register first

    Find out whether the property already has an energy certificate.

  2. 2

    Choose the right assessor type

    Domestic, commercial and public-building work can require different assessor competence.

  3. 3

    Describe the property accurately

    Provide the property type, size, location, access constraints and the reason the certificate is needed.

  4. 4

    Confirm the deliverable

    Ask whether the quote covers the assessment, certificate and applicable lodgement process.

Frequently asked questions about energy performance certificate cost.

Is there a fixed EPC price?

No. GOV.UK says assessment cost varies by assessor and property size. Commercial guidance says cost depends on the building being assessed.

Should I check for an existing EPC before paying?

Yes. Search the responsible official register first and confirm whether the existing certificate is valid and suitable for your task.

Does Adelphos sell EPC assessments?

This page does not advertise an assessor appointment or fixed assessment fee. Adelphos provides calculation workflows and scenario review; official certification follows the accredited-assessor route.

Does Adelphos issue an official EPC?

No. An official EPC must be produced and lodged through the applicable accredited-assessor process. Adelphos can calculate and compare supported scenarios, but its calculation output is not a lodged certificate.

Calculation and certification responsibility

The user is responsible for verifying every input, assumption, method, result and its suitability, and for obtaining competent-person review. Adelphos accepts no responsibility for decisions made using a calculation. Adelphos scenario output is not an official EPC or an equipment recommendation.
