Flats in Greater Manchester are far less likely than houses to have ever had an Energy Performance Certificate (EPC) lodged against them - and how big that gap is depends enormously on which of the conurbation's ten boroughs you're looking at.
Cross-referencing every residential address on the EPC register against Land Registry property types shows a striking split: across the ten boroughs, house EPC coverage barely moves (71.9% to 78.5%), but flat coverage ranges from 10.2% in Manchester to 50.4% in Bolton - a 40-point spread within a single conurbation.
What "coverage" means here
An EPC is only generated when a home is sold, let, or newly built - it isn't a periodic requirement like an MOT. So "coverage" (the share of addresses that have ever had a certificate logged) is really a proxy for how often a property changes hands or changes tenant, not a measure of how energy-efficient the local housing stock is. A low coverage rate means a lot of homes simply haven't been sold or re-let recently enough to trigger a certificate - not that they're hiding a poor rating.

Manchester is the mirror image of itself
The sharpest finding is inside Manchester itself: it has the highest house coverage of all ten boroughs (78.5%) and the lowest flat coverage (10.2%) - a 68-point gap within one local authority. Salford and Trafford follow a similar pattern, though less extreme. Between them, these three boroughs account for most of Greater Manchester's large build-up of city-centre and waterside apartment schemes (Manchester city centre, Salford Quays, Trafford's Stretford and Old Trafford corridor), where a big share of flats were completed and sold in a single registration event years ago and haven't changed hands since.
Stockport sits apart from both groups - its 26.4% flat coverage is well below the Bolton-to-Wigan cluster (46-50%) but nowhere near as low as the Manchester/Salford/Trafford trio. A simple "big-three cities versus the rest" story doesn't quite hold; Stockport is its own middle case.
Coverage doesn't track price
It's tempting to assume low coverage simply means "expensive flats that don't come to market often." The 2025 median flat sale price does line up loosely with the lowest-coverage boroughs here - Manchester (£220,000), Salford (£200,000) and Trafford (£200,000) are the three priciest flat markets in the conurbation, while Bolton (£116,500) and Wigan (£115,000) are both the cheapest and the best-covered. But this isn't a reliable rule: a national comparison of EPC coverage by area found Manchester's own 10.2% flat coverage sits almost level with Kensington and Chelsea's 9.4% - despite a 2025 median flat price gap of £955,000 versus £220,000. If coverage tracked price, those two boroughs wouldn't be anywhere near each other. Turnover - how often a flat is sold or newly let - is the better explanation than price level alone.
Why this matters if you're buying
If you're viewing a flat in Manchester, Salford or Trafford, don't be surprised if no EPC is on file - it's the norm rather than the exception in those boroughs' flat markets, and it says nothing about the property's condition. You can check whether a specific address already has a certificate using the government's own lookup before assuming you'll need to commission one. Houses are a different story everywhere in Greater Manchester: coverage sits in a tight 71.9%-78.5% band regardless of borough, so a house without any certificate on record is a bit more unusual than a flat without one.
For context, 2026-27 Band D council tax across the ten boroughs ranges from £2,152.68 (Wigan) to £2,618.90 (Stockport) - a reminder that coverage, price and council tax each follow their own logic and don't move together borough to borough.
