England has 164 shire districts sitting outside its cities and unitary authorities — the market towns, commuter belts and rural hinterlands that don't get their own headline house-price story. Ranking all of them by the share of homes rated EPC C or above turns up a top 15 dominated by one kind of place: the commuter-belt district building new estates around an old market town. Only one of the fifteen, South Derbyshire, is also cheaper to buy than the typical English home.
The 15 greenest shire districts in England, ranked
Homecost ranked all 164 English shire districts (local authorities with the "E07" code, excluding cities, London boroughs and unitary authorities) by the share of homes on the Energy Performance Certificate register rated C or above, using the latest certificate recorded for each address. Districts with fewer than 100 certificates were excluded to avoid small-sample noise.

The national median price for a residential sale in England in 2025 was £295,650, from 795,417 recorded transactions (HM Land Registry Price Paid Data). "vs national median" shows each district's 2025 median against that figure.
An EPC C+ share is a modelled rating, not a bill. It reflects a home's estimated energy efficiency under standard assumptions about heating and occupancy — not what any individual household actually pays, which depends on tariff, usage and how the property is run.
Two different green belts, one shared mechanism
The gap between a modern home and an old one on EPC ratings has one dominant cause: insulation and glazing standards tightened sharply from 2002's Part L update to the Building Regulations, and again in later revisions. Homes built after that point are rated C or above far more often than pre-1945 stock. Every district on this list has built new homes at a higher rate than the national norm over the past decade, which is the common thread behind an otherwise geographically scattered top 15.
But the kind of new building differs. South Derbyshire's 28.9% new-build share, the highest of the fifteen, comes largely from estate development on former coalfield land around Swadlincote and the wider South Derbyshire green belt — new housing replacing a shrinking industrial base. The other fourteen are almost all South East or East of England commuter-belt districts — Home Counties market towns absorbing overspill demand from London, Oxford, Cambridge and Southampton, where new estates get built at the edge of an existing town to meet housing targets, not to regenerate a former industrial site.
The one exception: cheap and green
Of the fifteen greenest shire districts in England, fourteen are priced at or above the national median. South Derbyshire, at £260,000, is the only one priced below it — 12.1% under the £295,650 national figure. Rugby is the next closest, at just 3.2% above. At the other end, Uttlesford's £475,000 median sits 60.7% above the national figure, and South Cambridgeshire's £440,995 is 49.2% above — both Home Counties districts where a strong EPC share sits alongside a heavy commuter premium rather than an affordable one.
That split matters for anyone using "green" as a shorthand for "affordable to run." A newer, better-insulated home in Uttlesford or South Cambridgeshire may cost less to heat than an older one nearby — but the purchase price attached to that efficiency is a different question entirely, and on this data, the two rarely move together outside South Derbyshire.
What it costs to run once you're in
Council tax follows its own logic, set by each local authority rather than by a property's age or energy rating. Band D bills for 2026–27 across the fifteen range from £2,255.21 in Basingstoke and Deane to £2,582.96 in Cherwell — a difference of £327.75, or 14.5%. Five of the fifteen (East Cambridgeshire, South Cambridgeshire, Vale of White Horse, Cherwell and Rugby) sit above the England-wide Band D mean of £2,410.97; the rest sit below it. There's no clean relationship between a district's EPC share and its council tax band — South Derbyshire, the cheapest to buy and greenest by EPC, sits almost exactly at the national council tax average, while Basingstoke and Deane, one of the priciest homes on this list, has the lowest Band D of the fifteen.
Try it on your own street
Homecost's postcode tool breaks down the true cost of a property in any of these districts — mortgage cost at today's rate, council tax band, EPC rating and stamp duty together in one place. A £260,000 purchase, South Derbyshire's 2025 median, sits close to the worked example in Homecost's true cost of buying a £250,000 home breakdown.
For the opposite pattern — districts where a low price comes with a colder EPC profile rather than a greener one — see where cheap-to-buy meets low EPC ratings. And for how much of a first-time buyer's stamp duty relief survives at shire-district prices, see the first-time buyer relief ceiling across England's shire districts.
