We put the price first, then the paperwork.
Most people looking for an EPC want one thing before anything else: a number. So we built the number into the front door, a price guide you can use without handing over an email address, and a plain explanation of what the fee covers.
An interactive reference, and a way to book.
The Observatory does two jobs. It explains what an Energy Performance Certificate costs in the UK and why that figure moves: floor area, property use, construction, heating, location and access. And it connects you to an accredited assessor who can carry out the assessment and lodge the certificate.
Everything about the pricing is stated as an indicative guide range rather than dressed up as a fixed offer. If a figure on this site could be mistaken for a quote, we label it.
Homeowners, landlords and agents
Selling a home, letting a flat, or handling a portfolio, the same tool serves all three, with a commercial route for shops, offices and units.
England, Wales, Scotland & NI
Coverage across all four nations, subject to local assessor availability. Requirements differ by nation.
Four commitments we hold ourselves to.
Not a mission statement, four things you can hold us to on any page of this site.
The price comes first
You get an indicative range before you give us a single detail. No gated calculators, no “call for pricing”, no email wall in front of a number.
Nothing hidden in the fee
The assessment, software, register lodgement, accreditation and insurance are covered by one quoted fee. No per room surcharges on a standard job.
Estimates labelled as estimates
A guide range is called a guide range. Anything that is not a confirmed quote for your specific property is marked as indicative, everywhere it appears.
A quote is not a commitment
Requesting a price starts a conversation, not a booking. You can take the figure away and do nothing with it, that is a perfectly good outcome.
A price before a conversation.
See an indicative range, understand what drives it, and decide in your own time. Nothing here asks for your email before it shows you a number.
- An indicative range before you share any details
- One inclusive fee, itemised in plain English
- Every estimate labelled as an estimate
Accredited people, approved methods, official records.
A certificate is only valid if the right person produces it with the right method and lodges it in the right place.
