The UK areas where fewest homes have ever had an EPC (2026)

Walk into a flat for sale in Manchester city centre and there's a good chance nobody can show you its official energy rating. Across England and Wales, 73.3% of houses have had an Energy Performance Certificate (EPC) logged at some point since the register began in 2008 — but only 30.8% of flats have (Energy Performance of Buildings Data, fetched 2026-10-08). Combined across both, 10,625,713 of 16,111,275 flat and house addresses — 66.0% — have ever been assessed. In some boroughs, fewer than 1 in 10 flats have ever had a certificate at all.

Why a certificate can simply not exist

An EPC isn't a standing requirement that sits on a home once and for all — it's triggered by a sale, a new tenancy, or new construction. A flat that hasn't changed hands, been re-let, or been built since 2008 can go the entire 18-year life of the register without ever being assessed. "No certificate on file" is therefore mostly a signal about how often a type of home changes hands locally, not about whether it's efficient or draughty.

This analysis counts an address as "covered" if at least one certificate has ever been lodged against it — not whether that certificate is still in date. It covers England and Wales only; the EPC register and HM Land Registry's Price Paid Data don't extend to Scotland or Northern Ireland.

Where flat coverage is lowest

Among local authorities with at least 300 flat addresses, these have the smallest share ever certified:

Seven of the twenty lowest-coverage authorities nationally are London boroughs. Several of the rest — Bournemouth, Christchurch and Poole; Brighton and Hove; Torbay; Eastbourne; Thanet — are coastal towns with large, long-standing stocks of retirement and holiday flats. Manchester and Salford, two of the cities most associated with the UK's modern city-centre apartment boom, also sit inside the bottom 20 — evidence that even newer flat markets can carry patchy certificate history if a meaningful share of units haven't resold or been re-let since completion.

At the opposite end, flats in these authorities have the most complete certificate history:

Post-war new towns (Telford and Wrekin, Harlow, Basildon all feature further down the full list), North East England authorities, and smaller flat markets in the East of England and East Midlands dominate this end — areas where flat stock tends to be smaller, newer, and to turn over more often.

It isn't simply about price

If low coverage tracked high prices alone, Manchester wouldn't sit a few places above Kensington and Chelsea on the same list. Checking 2025 Land Registry sale prices against coverage for a handful of contrasting authorities shows price and certificate history moving independently:

Manchester's flats sell for roughly a quarter of Kensington and Chelsea's, yet have slightly worse certificate coverage. The pattern tracks how often homes change hands far more closely than what they're worth.

Houses tell a related, but not identical, story

On houses, inner London again dominates the low-coverage end, joined by a different kind of area: places widely known for second homes and long-held rural property.

Beyond the top eight, the Cotswolds, North Norfolk, the Derbyshire Dales, Rother and Mole Valley all appear in the bottom 20 for houses — districts widely associated with holiday lets, second homes and long ownership tenures, where a house can go decades between sales.

Houses in cities and boroughs with large, actively re-let private rented stock sit at the other end:

Manchester is the clearest illustration of how differently the two markets can behave inside one local authority: its houses rank in the national top 10 for EPC coverage (78.5%) while its flats sit in the bottom 20 (10.2%) — a near-70-point gap driven by how often each type of home changes hands locally, not by anything about the city as a whole.

Every new tenancy in England and Wales legally requires a valid EPC, which likely explains why cities and boroughs with large, actively churning private rented housing — Nottingham, Peterborough, Barking and Dagenham, Newham — cluster at the high-coverage end for houses.

A prime-London footnote

Westminster and the City of London are the second- and third-cheapest Band D council tax bills in England for 2026-27, at £1,049.55 and £1,329.56 respectively; Kensington and Chelsea is fifth-cheapest, at £1,666.65. All three also sit among the local authorities with the thinnest EPC history on record, for flats and houses alike. None of this means the properties themselves are unusual — it's a reminder that in parts of prime central London, price, council tax band and energy paperwork can each sit far outside the national pattern, for reasons that have little to do with each other.

What this means if you're viewing a home

A missing certificate in the historical record doesn't mean a property is inefficient — it most often means nobody has sold, re-let, or built it since 2008. Any home currently marketed for sale or let in England and Wales must have a valid, in-date EPC produced before marketing starts, so one should exist, or be on order, for anything you're actually viewing or renting. If you're looking in one of the areas above, it's simply more likely that the only certificate you see will be a brand new one commissioned for this specific sale — worth asking the seller or agent for recent utility bills alongside it, since a certificate models costs on standard assumptions rather than measuring what the current occupant actually pays.
