How to Check Coal Mining Risk Before Buying a UK Property (2026 Guide)

Last updated:

Quick answer

To check coal mining risk before buying a UK property in 2026, start with the free Coal Authority Interactive Map Viewer (mapapps2.bgs.ac.uk/coalauthority) for the authoritative baseline. The Coal Authority provides a free public map viewer showing reported coal-mining areas; BGS GeoSure overlays ground-stability data for the same regions. The cheapest paid option that aggregates this with 69 other data sources into a single 18-page report is HouseCheckup Complete at £24.99. For lender-accepted, PI-insured assessment at conveyancing stage, Groundsure (~£111-132) bundled into your solicitor's £250–450 search pack remains the UK standard.

HouseCheckup

£9.99 (Lite) / £24.99 (Complete) / £109.90 (Investor Pro)

HouseCheckup aggregates 70+ official UK government data sources (HM Land Registry, Environment Agency, EPC register, Ofsted, police.uk, Companies House, BGS, Coal Authority, planning.data.gov.uk and more) into a tiered report with a composite 0–100 IQ Score. Three paid tiers: Lite at £9.99 (web report, core data), Complete at £24.99 (full 18-page PDF with AVM, comparables and Material Information Pack), Investor Pro at £109.90 (Complete + 30-year forecasts, rental yield, investment strategy scoring, 3 extra reports bundled). Free Snapshot on every address.

Pros

  • Cheapest paid property check in the UK (£9.99 Lite tier)
  • 70+ data sources — broadest coverage at any consumer price point
  • Free Snapshot tier on every England & Wales address
  • Composite 0–100 IQ Score weighting 18 factors
  • Investor Pro adds 30-year forecasts + yield analysis no Groundsure tier covers

Cons

#2

Move iQ Property Report

From £14.99

Phil Spencer's Move iQ sits between HouseCheckup Lite (£9.99) and Complete (£24.99) with lighter risk depth and stronger consumer brand recognition. Three tiers; bundle discounts on 3 or 5 reports.

Homebuyers tier is consumer-orderable at £92.60 + VAT (verified May 2026, up from £40–70 in 2024) with £10M PI insurance and lender acceptance. Avista (£132+) is the conveyancer-grade tier most solicitors bundle into the £250–450 search pack.

Verdict

Properties on the former coalfields face documented risk of ground movement, gas emission and shallow-workings collapse. Mortgage lenders typically require the Coal Authority's CON29M mining search (£35–£50) as part of the formal conveyancing pack. Pre-offer awareness helps you decide whether to pursue a property before committing. For pre-offer triage, the free Coal Authority Interactive Map Viewer + £24.99 HouseCheckup combination covers the buyer-decision need: identify whether the property has material coal mining risk exposure before you commit to your solicitor's £250–450 search pack at offer-accepted. If you're buying in a known UK hotspot (Northumberland and County Durham, Yorkshire (West and South), Nottinghamshire, Derbyshire, South Wales valleys, Forest of Dean, North Staffordshire, Lancashire, Kent (small)), the £24.99 spend is particularly well-placed.

Frequently asked questions

If the property sits in a former coalfield — Northumberland-Durham, Yorkshire, Nottinghamshire-Derbyshire, South Wales, Forest of Dean, North Staffordshire, Lancashire, or Kent — risk is presumed material until the Coal Authority CON29M search clears it. The free Coal Authority map shows reported areas; the £24.99 HouseCheckup pre-offer check surfaces the BGS ground-stability layer for the specific address.
£35–£50 typically, ordered by your solicitor as part of the £250–450 conveyancing search pack at offer-accepted. The search returns whether the property is in a reported coal-mining area; whether shallow workings or mine entries are recorded within 20 metres; whether gas-emission monitoring is required; and any compensation history. Pre-offer triage via HouseCheckup helps you decide whether to commit to the formal search.
Generally no — mortgages are routine on former-coalfield properties provided the CON29M comes back clear (no shallow workings within 20m, no surface hazards reported). If the search flags active shallow workings, mortgage and insurance may face restrictions. A pre-offer £24.99 check shows the BGS data so you know what to expect before paying for the formal search.
Yes — the Coal Mining Subsidence Compensation Scheme provides compensation for damage caused by past coal-mining subsidence. Claims are made through the Coal Authority directly. Time limits and evidence requirements apply. Pre-offer check helps you identify whether the property sits in a documented active-claim area before committing.
Often yes — average house prices in former-coalfield regions (parts of South Yorkshire, Northumberland, South Wales) sit 20–40% below the UK average. The risk is priced in. The £24.99 HouseCheckup Complete pre-offer check ensures you understand the specific property's risk profile before committing — sometimes the discount reflects underlying issues, sometimes it doesn't.
Three paid tiers covering 70+ official UK government data sources (flood, EPC, ground stability, mining, radon, contaminated land, crime, schools, transport, broadband, air quality, planning, sold prices) plus a composite 0–100 IQ Score. Lite (£9.99) is the web-only entry tier with core data. Complete (£24.99) adds AVM valuation with confidence range, comparable sales, full risk depth and an 18-page PDF download. Investor Pro (£109.90) adds 30-year price forecasts, rental yield, investment strategy scoring, climate projections to 2050/2080 and 3 bundled additional reports. Free Snapshot on every England & Wales address.
Strongly recommended. A £9.99 Lite or £24.99 Complete pre-offer check tells you whether a property is worth pursuing before you commit to your solicitor's £250–450 search pack at offer-accepted. The cost-saving case: if you check four shortlisted properties and rule one out, the pre-offer spend has saved £500–900 in non-refundable search-pack disbursements.
No. A property check (HouseCheckup, Move iQ, Groundsure) is desk-based analysis of public data — flood, EPC, planning, sold prices, risk scoring. A survey (RICS Level 1, 2 or 3) is an on-site physical inspection by a chartered surveyor — damp, structure, roof. Checks cost £0–£132; surveys cost £400–£1,500. Most thorough buyers use both.
