Property information
What an EPC actually tells you
An energy performance certificate rates a building from A to G and lists recommendations. It uses standard occupancy assumptions, so it does not predict a particular household's bills.
Pending client evidence Whether Dukes provides, arranges or refers EPC assessments is not confirmed. Until it is, the official routes below are the primary actions and no Dukes booking, price or service claim appears.

- E 39–54 Below average
- F 21–38 Inefficient
- G 1–20 Least efficient
Each band states its letter, its range and its meaning in text, so the colour is never the only way to read it. The bands appear once, in order, and never replay.
When an EPC is needed
A property being sold or rented must have an EPC commissioned before marketing where no valid certificate exists, and the rating must appear in the advertisement. Certificates are generally valid for ten years, and only an accredited assessor can produce one.
For landlords in England and Wales, covered privately rented properties cannot be let, or continue to be let, below EPC E unless a valid exemption applies. Enforcement sits with the local authority.

EPC FAQs
Can Dukes arrange an EPC for me?
Not stated here. The company was previously named EPC 4U LTD, but a former company name is not evidence of a current service. Until the provider, accreditation, fee, VAT treatment and complaint route are supplied, no booking or arranging claim can appear.
Does an EPC tell me what my bills will be?
No. The rating uses standard occupancy assumptions, so real bills depend on how the household actually lives in the property.
What is the difference between the current and potential rating?
The current rating reflects the property as assessed. The potential rating shows what could be achieved if the listed recommendations were carried out. They are always shown as two separate figures.
