Residential and commercial EPCs

Do New Build Properties Need an EPC?

New buildings need energy performance documentation too. For a new home, the completed EPC should reflect what was actually built, rather than being confused with a design-stage calculation.

New does not mean exempt

GOV.UK includes building a new property among the circumstances requiring an EPC. Buyers should ask for the certificate for the completed dwelling, even if the sales material describes the development as energy efficient.

A brochure's predicted rating is not the same document as the final lodged certificate. Confirm the exact plot and postal address so that a record for another home on the development is not supplied by mistake.

On-construction and existing-home assessments

A newly constructed dwelling uses an assessment route based on the relevant construction information. Plans, specifications and evidence of the completed building are important. This is different from the usual reduced-data assessment of an existing home.

Tell EPC Agent if the property is a new build or conversion before booking. We can discuss the appropriate assessment enquiry; do not assume that a standard existing-property appointment covers building-regulations calculations or every on-construction deliverable.

Design information versus the completed building

An early calculation can support the design process, while the finished certificate must reflect the completed building under the applicable requirements. Changes to insulation, glazing or services during construction therefore need to be captured in the final documentation.

Developers and self-builders should coordinate the energy assessor, designer and building-control process early. Ask which records and test results are needed for the particular project, and keep revisions organised so the final assessment does not rely on superseded specifications.

A buyer's document checklist

  • The final EPC for the correct home and address.
  • Its official register entry and validity details.
  • Relevant installation and operation information for heating and controls.
  • Clarification where a plot number differs from the postal address.
  • An explanation if a predicted marketing rating differs from the final result.

Read the certificate alongside the rest of the purchase documentation. It does not replace building-control records, warranties or a survey. If an address or feature appears wrong, raise the specific issue with the developer and assessor rather than editing the document yourself.

Conversions need particular care

Creating separate dwellings from an existing building can involve a different assessment requirement from simply selling the original property. A house converted into flats should not automatically reuse the whole-house certificate for each new unit.

Explain the previous and new uses, number of units and building work. Appropriate advice at the start can prevent a late discovery that the wrong assessment was commissioned. The same principle applies when considering newly created commercial units or mixed-use accommodation.

Does a new home always achieve an A?

Do not infer the final band from the building's age alone. The certificate is based on the applicable calculation and recorded features. Marketing claims about an entire development should not be substituted for the result for a specific dwelling.

Similarly, a high rating is not a guarantee of a household's exact bills. Occupancy and tariffs still matter. Read EPC ratings explained to understand the current and potential figures.

Frequently asked questions

Can I find my new home's EPC online?

Use the official register search. If the address is not found, ask the developer for the certificate reference and check the plot-to-postal-address details.

Is the predicted EPC in a brochure sufficient?

Ask for the final lodged certificate for the completed home. A design prediction is not a substitute for the correct completed record.

Does an extension always mean a whole new EPC?

Do not equate every extension with constructing a new dwelling. Explain the project and transaction so the applicable building and EPC requirements can be checked.

Can I enquire locally?

See EPC services in Sutton Coldfield or contact EPC Agent, clearly stating whether the enquiry concerns an existing home, new build or conversion.
