Coal Mining Under New Build

Holmes21

Hi folks,

So I am about to buy a new build and got the coal report in, one of the points states:
’the property is in a surface area that could be affected by underground mining in 8 seams of coal at shallow to 180m depth, last worked in 1926’.

I am obviously concerned by this and not sure what to do. Having spoken to some friends they have advised that half the UK is built on top of old mines.. 

My concerns are subsidence, any gasses leaking from the ground and issues when I come to extend it or more importantly sell the property. 

What are your thoughts on this?

Anyone bought a similar property?

Thanks for your help.

Have you checked the planning papers? There'll almost certainly be a much more detailed geotechnical report there about their investigations, and explaining what measures if any they've taken. The planners won't have let them build something destined to fall down a mineshaft.

No issues at all!.
Any subsidence would have been long since done in any longwall mine. No real issue with methane. Gassy pits when closed had methane vents. 
Movement often occured when mines were opened. 
What area are you buying in?  Dont let coal mining issues put you off. So many houses built in old  coalfield areas no issue.
Id be worried about buying a tin pot new build rather then something well built

I can't see it being an issue from such a long time ago but it reminds me of a local 70's estate where there is a gap in the houses where one sunk into an old mine....

Yes has happened in areas like wigan where lots of recorded shafts or shafts that have collapsed because of poor fill.

no need to worry about as the issues were long long time ago.!!!!

I haven’t no, how would I get access to them? Thanks.

By finding the planning application for the development on the council's website.

Buying in Scotland, New builds are
not always the best quality admittedly…
