Across 49,270 Leicester homes with a current Energy Performance Certificate, 29.4% are rated C or better. But the city's five main postcode districts split sharply on that figure — and not in the way a buyer comparing prices would expect. Leicester's cheapest postcode to buy into is not its greenest. Its two oldest, most expensive-to-buy inner districts rate among the coldest. The gap tracks when a home was built, not what it costs.
This is a look at how energy ratings are distributed across Leicester's LE postcode districts, using Energy Performance Certificate lodgements and HM Land Registry sold-price records. It reports what the data shows about the existing housing stock — not what any individual home is worth, and not what anyone should do about it.
Figures below were compiled on 1 November 2026 from the current EPC register (latest certificate per address, so re-lodged and superseded certificates aren't double-counted) and Land Registry price-paid records for 2025 (standard sales of houses and flats in the City of Leicester local authority, E06000016). Council tax is the 2026-27 Band D charge.
Energy ratings by postcode
The table below ranks Leicester's five main postcode districts by 2025 median sold price, alongside the share of homes rated EPC C or better. All five districts clear at least 50 sales and 200 current certificates.
| Postcode | Main areas | 2025 median price | 2025 sales | EPC C or better |
|---|---|---|---|---|
| LE1 | City centre | £126,250 | 56 | 22.4% |
| LE3 | Braunstone, Westcotes, New Parks | £205,000 | 535 | 23.4% |
| LE2 | Clarendon Park, Stoneygate, Aylestone, Knighton | £235,000 | 663 | 22.3% |
| LE4 | Beaumont Leys, Rushey Mead, Belgrave | £255,000 | 562 | 36.2% |
| LE5 | Evington, Humberstone, Thurnby Lodge | £272,750 | 540 | 35.9% |
LE1, the cheapest district on this list at a £126,250 median, is also one of the coldest on paper, at 22.4% C-or-better — behind LE2 and LE3, which are both dearer. That's a different shape to the inversion seen in some other English cities, where the cheapest postcode is also the warmest. Leicester's city centre is unusual here because it is overwhelmingly a flat market (around seven in ten LE1 homes on record are flats and conversions, not houses), so its low median reflects flat prices rather than an updated or modern building stock.
LE4 and LE5, the two priciest districts on the list, are also the two greenest — both clear 35% C-or-better, roughly 13 percentage points above LE2 and LE3. That is the opposite of the "cheaper buy, warmer home" pattern found in some cities, and it isn't a price effect either: LE5 is only 7% dearer than LE4 but has a near-identical EPC share. Price and energy rating both move with a third factor — how old the stock is.
Why the gap follows build era
Sorting Leicester's certificates by construction era produces a steep, consistent gradient:
| Build era | Share rated C or better |
|---|---|
| Before 1950 | 10.7% |
| 1950–1982 | 36.1% |
| 1983–2002 | 54.7% |
| 2003 onwards | 96.7% |
Homes built before 1950 make up 59.0% of Leicester's certificates with a recorded construction date — and only 10.7% of that pre-1950 stock reaches band C or better. The step up to 1950–1982 stock very nearly matches the citywide average on its own; anything built since 2003 is rated C or better almost without exception, in line with the tightened insulation, glazing and heating standards introduced for new homes in England and Wales by the 2002 revision to Part L of the Building Regulations.
That explains the postcode table closely. LE2 is 71.9% pre-1950 stock and just 3.9% built since 2003 — the Victorian terraces of Clarendon Park and Stoneygate, with very little modern infill. LE3 is a near-identical 66.6% pre-1950 and 4.0% post-2003 — Braunstone and Westcotes follow the same pattern. Compare that with LE5, at 52.2% pre-1950 but 10.2% built since 2003, and LE4, at 43.5% pre-1950, both reflecting more interwar and postwar estate housing and more recent infill around Beaumont Leys, Rushey Mead and Thurnby Lodge. LE1's own figure (62.1% pre-1950, only 4.7% post-2003) shows its low EPC share has the same cause as LE2 and LE3 — an old core, in this case largely converted into flats rather than kept as whole houses.
As in other cities Homecost has mapped this way, including the equivalent breakdowns for Doncaster's EPC retrofit gap and Rotherham's EPC ratings by outcode, this is best read as a story about housing stock, not about the people who live in each postcode.
What a rating band means for running costs
An EPC estimates how efficiently a home uses energy, and a lower band generally implies higher modelled heating and lighting costs than a higher band of comparable size. The certificate also lists modelled improvements — insulation, glazing, heating upgrades — that would move a property up the scale. Those are modelled figures, not bills, and actual costs depend on the property, its occupants and prevailing energy prices. For how the bands translate into typical running costs, see EPC ratings explained for house buyers and the worked comparison in energy cost by EPC rating.
Across the city, 2.8% of homes (1,394 of 49,270) sit in the lowest F or G bands — a small minority, concentrated in the same pre-1950 core that dominates LE1 to LE3.
The cost side
For context on the purchase side, Leicester's 2025 median across all five districts stood at £242,000 from 2,361 standard sales — see the full house-price breakdown for Leicester for the by-type figures. At that median, Stamp Duty Land Tax works out at £2,340 for a home mover, £0 for an eligible first-time buyer (the median sits below the £300,000 nil-rate threshold), and £14,440 where the additional-property surcharge applies (HMRC rates, 2026).
Council tax is charged on top: Leicester's 2026-27 Band D is £2,528.75. On a 25% deposit and a 25-year term at the Bank of England's latest quoted 75%-LTV five-year fixed rate of 4.32% (April 2026), the mortgage on the median home works out at roughly £990 a month, plus around £211 a month in council tax — about £1,201 a month before energy, buildings insurance or maintenance, and before any energy-efficiency gap in the property itself is factored in.
This is general information, not advice. Energy-efficiency work, mortgage costs and stamp duty all depend on individual circumstances — speak to a qualified adviser before acting.
