Coal mining search by postcode — is a CON29M going to be demanded?
Historic coal workings and flood zones screened against Mining Remediation Authority (formerly Coal Authority) and Environment Agency open data. Indicative screening for £14.50 — not a CON29M official mining search.
Free teaser: coal high-risk area · flood zone · lender clearance hint. Full certificate £14.50.
Mining Remediation Authority polygons where shallow coal workings, mine entries or mine gas may affect the surface.
Environment Agency river and sea flood zones via planning.data.gov.uk.
Whether a CON29M search is likely to be demanded before mortgage offer — and what it would add.
Mining risk by town
Live screening of a central postcode in each coalfield town.
Mining report needed for mortgage?
Inside the coal mining reporting area most lenders require a CON29M coal mining search before offer. This screening tells you in seconds whether your postcode sits in that area and whether it is a Development High Risk Area, so you can budget and avoid a late surprise.
Coal Authority report cost
A CON29M official search is ordered through your conveyancer at the Mining Remediation Authority's published fee. Our £14.50 certificate is a preliminary screening from open data — it does not replace the CON29M but tells you what it is likely to say.
This screening vs a CON29M official coal mining search
This screening tells you whether a CON29M is likely to be demanded and what it is likely to say. It does not replace it. If you are buying with a mortgage inside the coalfield, budget for the CON29M regardless of this result.
