Rotherham EPC ratings by postcode: cheap to buy, cold to run in 2026
In Rotherham, the postcodes where a home costs the least to buy tend to be the same ones where it costs the most to keep warm. Across the borough, 41.2% of homes hold an Energy Performance Certificate (EPC) rating of C or better — the band the government treats as the modern efficiency benchmark. That headline hides a wide split between outcodes, and the split lines up closely with age of housing stock, which in turn tracks price.
The figures below come from the Energy Performance of Buildings register (latest certificate per address) alongside HM Land Registry Price Paid Data for 2025 completed sales. They describe what has been recorded and paid — not what any individual home is worth.
The split, outcode by outcode
The table ranks Rotherham's main outcodes by 2025 median sale price, lowest first, with the share of homes rated EPC C or better alongside.
| Outcode | Main areas | 2025 median sale price | 2025 sales | Homes rated EPC C+ |
|---|---|---|---|---|
| S62 | Rawmarsh, Parkgate | £163,000 | 219 | 34.6% |
| S61 | Kimberworth, Thorpe Hesley, Greasbrough | £170,000 | 404 | 35.5% |
| S65 | Clifton, Dalton, Thrybergh, Ravenfield | £170,000 | 339 | 33.5% |
| S64 | Swinton, Kilnhurst | £180,000 | 199 | 40.8% |
| S63 | Wath upon Dearne, Brampton Bierlow | £186,000 | 243 | 50.2% |
| S66 | Maltby, Bramley, Wickersley, Thurcroft | £190,000 | 610 | 42.0% |
| S25 | Dinnington, Anston, Laughton | £195,000 | 324 | 42.3% |
| S26 | Aston, Swallownest, Kiveton Park | £237,250 | 362 | 42.4% |
| S60 | Brinsworth, Whiston, Waverley, Treeton | £240,000 | 634 | 48.6% |
Median sale price: HM Land Registry standard-price transactions, 2025 calendar year (outcodes with at least 30 sales). EPC share: latest certificate per address on the Energy Performance of Buildings register (outcodes with at least 200 certificates). Data retrieved 31 August 2026.
The three cheapest outcodes to buy into — Rawmarsh and Parkgate (S62, £163,000), Kimberworth and Thorpe Hesley (S61, £170,000) and the Clifton–Dalton–Thrybergh belt (S65, £170,000) — all sit below the borough-wide 41.2% figure for EPC C-or-better homes. At the other end, the dearer southern and eastern fringe pairs higher prices with newer, more efficient stock: Brinsworth, Whiston and the Waverley development (S60) reach 48.6% at a £240,000 median, and Aston and Kiveton Park (S26) reach 42.4% at £237,250.
The exception that proves the mechanism
The pattern is not a straight line. Wath upon Dearne and Brampton Bierlow (S63) buck it cleanly: at a mid-range £186,000 median, it is the greenest outcode in the borough at 50.2% C+. The reason is the same one that drives the rest of the table — the age of the homes. The Dearne Valley has seen substantial new-build activity, and newer homes rate far higher on the certificate.
That link between construction era and EPC band is stark in Rotherham's own data:
| Construction era | Homes rated EPC C+ |
|---|---|
| Before 1900 | 8.0% |
| 1900–1929 | 15.7% |
| 1930–1949 | 25.1% |
| 1950–1966 | 29.8% |
| 1996–2002 | 47.2% |
| 2003–2006 | 95.2% |
| 2007 onwards | ~98% |

The jump between homes built up to 2002 and those built from 2003 is the clearest break in the dataset — reflecting the tightening of the Building Regulations energy-efficiency standards (Approved Document L) that took effect in the early 2000s. Outcodes weighted towards Victorian and inter-war terraces — common in the older industrial belts north and east of the town centre — carry more of the low-rated stock. Outcodes with more post-2000 estate housing, whether on the affluent southern fringe or in a regeneration area like the Dearne Valley, carry more of the high-rated stock. The difference is about when the houses were built, not about the people who live in them.
Why the band matters for the running cost
An EPC grades a home from A (most efficient) to G (least), based on a standard assessment of the building fabric and heating system. A lower band generally means more heat lost and a higher modelled cost to keep the home at a comfortable temperature. It is a modelled comparison, not a bill — actual costs depend on how a household lives, the Ofgem energy price cap in force, and any fixed tariff. For a worked illustration of how running costs change across the bands, see our guide to energy cost by EPC rating for a 3-bed semi, and for how the certificate itself is put together, what an EPC rating means for house buyers.
The practical point for anyone weighing a Rotherham purchase is that the cheaper purchase price in an older-stock outcode can come with a higher energy bill and a longer list of efficiency improvements on the certificate's recommendations page. An EPC includes those recommendations and their indicative costs; a full survey and a chartered surveyor can assess what a specific property needs. Government-backed help with efficiency upgrades exists for eligible households through schemes such as the Energy Company Obligation, and the certificate for any address is free to look up on the public register.
Council tax adds a further fixed line to the monthly cost. Rotherham's Band D charge for 2026-27 is £2,381.53 (council tax levels, gov.uk), applied borough-wide rather than by postcode, so it does not move between the outcodes above.
How this fits the wider picture
Rotherham's citywide 41.2% C+ share sits close to the roughly 40% seen across neighbouring South Yorkshire boroughs. The same age-driven pattern shows up next door — see our breakdown of Sheffield EPC ratings by postcode and the wider Sheffield, Rotherham, Barnsley and Doncaster buy-versus-run comparison. It is not unique to the region: the East Lancashire terraced-belt retrofit gap tells a similar story in the North West.
