Red Ash Areas in Stoke-on-Trent: Map & Area Guide

Updated August 2026.

People search for a red ash map of Stoke-on-Trent expecting a shaded diagram with their street either inside the line or outside it. No such map exists, and this page will not invent one. What does exist is a housing profile — a build era, a floor type and a coalfield underneath nearly all of it — and that profile is genuinely useful for working out whether your house is worth testing. Below is an area-by-area guide, with the basis for every area stated so you can judge it yourself. We have bought houses with red ash floors across the ST postcodes since 2016, and we have said plainly where we are guessing and where we are not.

Which areas of Stoke-on-Trent have red ash?

Red ash floors are found right across Stoke-on-Trent and Newcastle-under-Lyme rather than in one district. The reliable indicator is not the postcode but the house: built roughly 1940 to 1970, with a solid concrete ground floor, and very often ex-local-authority. Areas where that profile is common include Bentilee, Blurton, Smallthorne, Longton, Burslem, Tunstall, Chell and Norton — but only a test confirms an individual house.

That last point is not a disclaimer bolted on the end. Neighbouring houses on the same street, built in the same month by the same contractor, routinely differ: it depended on which filler was on the lorry that day. An area listing tells you whether testing is worth the money. It does not tell you what is under your floor.

Areas commonly associated with red ash — and what each listing is based on

• Bentilee, Blurton, Smallthorne, Longton, Burslem and Tunstall — basis: our own buying record. These are areas we have bought houses in since 2016, red ash among the recurring reasons a sale had stalled. Large volumes of post-war local-authority housing on solid floors.
• Chell and Whitfield (north of the city) — basis: documented former colliery ground. Chatterley Whitfield Colliery sits on the northern edge of the city and is a scheduled monument on the National Heritage List for England (list entry 1015947). Colliery shale and ash were abundant locally in exactly the decades this housing went up.
• Norton (Norton-in-the-Moors) — basis: documented former colliery. Norton Colliery is recorded in the National Archives' catalogue of colliery photographic records for Norton-in-the-Moors, Stoke-on-Trent.
• Longton (Mossfield) and Florence — basis: documented former collieries. Mossfield Colliery, Longton, and Florence Colliery, Florence, both appear in national archive records; Florence merged with Hem Heath in 1974 to form the Trentham complex and closed in 1994.
• Trentham and the south of the city — basis: documented former colliery. Hem Heath Colliery, off Longton Road, Trentham, is recorded in the National Archives' colliery photographic catalogue.
• Newcastle-under-Lyme — basis: the same coalfield and the same build era, with a comparable stock of local-authority housing from the same decades. We buy there too.

Two honest limits on that list. First, a former pit nearby explains why ash was cheap and plentiful in an area — it is not evidence that any particular house was built on it. Second, the absence of an area from this list means we have no documented basis to include it, not that it is clear. Plenty of red ash sits under houses in areas nobody thinks of as mining areas.

Why do these areas have red ash floors?

Because the material was free and local. Burning coal at the pits and the potbanks left behind shale and ash in enormous quantities, and from the 1940s to the 1970s — when building materials were scarce and then simply expensive — that waste was used as hardcore under concrete ground floors. Stoke-on-Trent sits on the North Staffordshire Coalfield, so the supply was on the doorstep of nearly every estate being built.

The problem is chemistry rather than workmanship. Red ash contains sulphates. Where moisture reaches them under a concrete slab, the reaction expands the material, and the floor above it heaves — doming in the middle of a room, cracking, lifting tiles, catching doors. It takes years to show, which is why it surfaces during a sale rather than during the years of living there. The full mechanism and what it costs to put right is set out on our main guide: what is red ash.

Is my house in a red ash area?

Check three things in order: the build era (roughly 1940–1970 is the window), the floor construction (solid concrete, not suspended timber — a floor that sounds hollow underfoot is almost certainly not the problem), and the signs (a domed or bulging ground floor, cracked concrete, lifted tiles, doors that now catch, skirtings pushed upward). A house matching all three is worth testing.

Tenure history matters as much as location. Ex-local-authority houses from those decades are over-represented, which is why the area names above are mostly big post-war estates. But privately built houses of the same era on the same ground are not exempt — they were built by the same firms using the same suppliers.

If your house is a Victorian terrace with suspended timber floors, or a 1990s build, red ash is not your issue. If it is a 1950s semi in Bentilee with a bulge in the kitchen floor, it is the first thing to rule out.

What should I do if my house is in a red ash area?

Get it tested before you do anything else. A red ash investigation means drilling core samples through the floor and lab-testing them for sulphate content: locally, expect roughly £150–£300 for sampling and analysis on a typical house. That number is worth spending even if you are not selling yet, because it converts a rumour about your street into a fact about your house.

If the test is clear, you have a document that stops the question being raised again during a sale. If it confirms red ash, you have three realistic routes: dig out and replace the floors, which in 2026 means budgeting £15,000–£30,000+ on a typical terrace with the house uninhabitable during the works; sell on the open market with the problem disclosed, accepting a smaller pool of buyers because most lenders will not lend against it; or sell to a cash buyer who takes the house as it stands.

We are the third option, and we will be straight about the trade-off: we buy below market value. What you get for that is a fixed figure, no fees, no viewings, no chain, no survey renegotiation, and legal fees paid up to £400. Once you accept a confirmed offer we do not pull out. Completion can follow in as little as a month. If your house is mortgageable and you can wait three to six months, an estate agent will very likely get you more — we would rather say so here than at the end of a visit.

You do not need to have tested before talking to us. We buy red ash houses suspected, confirmed, tested or untested.

Why isn't there an official red ash map?

Because nobody has ever surveyed it. Red ash was a construction shortcut, not a planning designation — it was never recorded property by property, so there is no register to map from. Testing happens house by house, usually triggered by a sale, and those results stay private between the owner, the surveyor and the lender.

Anything presented online as a definitive red ash map of Stoke-on-Trent is therefore someone's best guess drawn as though it were data. We would rather give you the build-era profile, the areas we can evidence, and an honest note that the only thing which settles it for your address is a core sample.
