Coal Mining Areas in the UK: What Property Buyers Need to Know (2026)
Updated 29 May 2026
Roughly 1 in 4 (about 25%) of properties in England and Wales sit in a coal mining reporting area defined by the Coal Authority. If a property does, conveyancers usually recommend a CON29M coal mining search, which typically costs around £30 to £60. The search checks for past mine workings, shafts and ground stability risks before you commit to buying.

What a coal mining reporting area is
The Coal Authority, a public body, maintains the official record of areas affected by past and present coal mining across Great Britain. These are known as coal mining reporting areas. According to the Coal Authority, around 1 in 4 properties in England and Wales fall within one.
Sitting in a reporting area does not mean a property is unsafe. It means there may have been coal mining activity nearby, historically or more recently, and that a buyer should check the official records before purchase. Most homes in coalfield regions are perfectly stable, but the search exists to flag the minority where past workings could affect the ground.
Where the former coalfields are
Britain's coalfields are concentrated in well-documented regions. The main areas include South Wales, the Midlands, Yorkshire, the North East and Lancashire, together with Scotland's central belt.
If you are buying in one of these regions, there is a higher chance the property is in a reporting area and that a coal mining search will be recommended. The British Geological Survey publishes information on the underlying geology and mining-related ground hazards that sit beneath these regions.

The coal mining search and what it costs
When a property is in a coal mining reporting area, conveyancers typically order a CON29M coal mining search. It is a standardised report that looks at past underground and surface mine workings, mine entries such as shafts and adits, and any recorded ground stability or subsidence risk linked to mining.
A coal mining search usually costs around £30 to £60. It is one of the cheaper property searches, and lenders often expect it where a property is in a reporting area, so it is rarely worth skipping on a coalfield purchase.
How to check before you buy
You do not have to wait for your solicitor to find out whether a property is in a coal mining area. A free HomeBuyerCheck report flags whether any specific UK address sits within a coal mining reporting area, alongside flood risk, crime and the nearest schools with their Ofsted ratings.
That early signal helps you decide whether to budget for a CON29M search and ask the right questions before you make an offer, rather than discovering the issue weeks into conveyancing.
