Across Lincolnshire's nine district and unitary councils, the share of homes rated EPC C or better ranges from 34.5% in East Lindsey to 48.9% in North Kesteven — a 14.4-percentage-point spread inside a single county (Homecost analysis of 241,515 EPC certificates, fetched 19 September 2026). The instinctive explanation would be that the cheapest areas simply run coldest. That isn't what the data shows. East Lindsey, the lowest-rated district, sits in the middle of Lincolnshire's price ladder, not the bottom. The real driver is a housing-stock quirk: East Lindsey has by far the county's highest share of bungalows, and bungalows underperform on EPC almost everywhere they're built.
The nine-district ladder
All figures are 2025 median sale prices (HM Land Registry, category A residential transactions) and EPC ratings from the latest certificate per address, cross-checked against 2026-27 council tax Band D rates.
| District | 2025 median price | 2025 sales | EPC C+ share | Band D 2026-27 |
|---|---|---|---|---|
| North Kesteven | £245,000 | 2,054 | 48.9% | £2,337.81 |
| West Lindsey | £235,000 | 1,714 | 47.8% | £2,354.25 |
| South Kesteven | £260,000 | 2,376 | 46.1% | £2,260.00 |
| South Holland | £235,000 | 1,600 | 43.6% | £2,278.20 |
| Boston | £212,500 | 924 | 40.8% | £2,308.73 |
| North Lincolnshire | £178,000 | 2,458 | 39.0% | £2,348.46 |
| Lincoln | £190,000 | 1,269 | 38.7% | £2,323.08 |
| North East Lincolnshire | £165,000 | 2,338 | 35.0% | £2,483.85 |
| East Lindsey | £217,000 | 2,258 | 34.5% | £2,275.88 |
Price alone doesn't explain the gap
If cheap-to-buy areas were simply cheap-to-run, North East Lincolnshire — the county's least expensive district at a £165,000 median — and East Lindsey — its lowest-rated on EPC — would be the same place. They aren't. North East Lincolnshire is £52,000 cheaper than East Lindsey on the 2025 median, yet rates half a percentage point higher on EPC C+ share. At the other end, South Kesteven is the priciest district at £260,000 but sits mid-table on EPC, beaten by both West Lindsey and North Kesteven, which are cheaper to buy. There's a loose tendency for pricier districts to rate slightly better, but it breaks down repeatedly across the middle of the table.
Why East Lindsey runs cold: bungalows, not age
The usual suspect for a low EPC score is old housing stock — solid-wall Victorian terraces built before cavity-wall construction became standard. That's not what's happening here. East Lindsey's pre-1930 housing share (19.2% of certificates) is lower than North East Lincolnshire's (30.1%) and Boston's (21.8%). If age were the main driver, East Lindsey should out-rate both of them. It doesn't.
What East Lindsey does have is bungalows — 38.8% of its EPC stock, nearly double the next-highest district (South Holland, 24.1%) and roughly three times North East Lincolnshire's share (13.2%):
| District | Bungalow share of stock | EPC C+ share |
|---|---|---|
| East Lindsey | 38.8% | 34.5% |
| South Holland | 24.1% | 43.6% |
| North Kesteven | 23.0% | 48.9% |
| Boston | 20.9% | 40.8% |
| West Lindsey | 19.6% | 47.8% |
| North Lincolnshire | 17.1% | 39.0% |
| North East Lincolnshire | 13.2% | 35.0% |
| South Kesteven | 13.1% | 46.1% |
| Lincoln | 9.8% | 38.7% |
Splitting East Lindsey's own certificates by property type shows why this matters: houses in East Lindsey rate 40.0% C+, but bungalows in the same district rate only 25.8% — a 14-point gap inside one district's stock, explained entirely by building type. For comparison, North Kesteven's bungalows rate almost identically (25.2% C+) to East Lindsey's — the type effect is consistent — but North Kesteven has far fewer of them (23.0% of stock against East Lindsey's 38.8%), so the drag on its overall average is smaller.
The mechanism is structural rather than a quirk of Lincolnshire's stock specifically: a bungalow has a much larger roof and external-wall area relative to its floor space than a two-storey house of the same footprint, so heat loss per square metre is inherently higher before any question of age or renovation. It's a pattern that shows up in EPC data nationally, not something unique to this county.
What this means for buyers
At every one of the nine 2025 medians, a first-time buyer purchasing a main residence in England would fall under the £300,000 nil-rate stamp duty threshold, meaning no SDLT would be due on the property itself (HMRC, 2026). A home mover, who doesn't get the first-time buyer nil-rate band, would pay stamp duty ranging from roughly £800 at the North East Lincolnshire median up to £3,000 at the South Kesteven median. Whether either relief actually applies depends on individual circumstances — a conveyancer confirms eligibility on completion, and this is general information, not advice.
For anyone weighing EPC-linked running costs alongside the purchase price, the practical read is specific rather than general: a bungalow in East Lindsey is statistically the least likely property type and district combination in this county to already sit at a C rating, while a similarly priced bungalow in North Kesteven or South Kesteven is more likely to. That's a reason to check a property's actual EPC certificate rather than assume rating from price or postcode alone.
