Whether a CON29M search is likely to be demanded before mortgage offer — and what it would add.
Do I need a mining report for a mortgage in Wigan?
Most of Wigan lies inside the coal mining reporting area, so lenders normally require a CON29M search. Our screening tells you whether your postcode is also inside a Development High Risk Area, which affects planning for extensions and new builds.
What does the £14.50 certificate give me?
A dated PDF with coal status, flood zone, OS grid reference, lender and planning hints, and a plain-English list of what the CON29M would add. It helps you decide and budget; it does not replace the CON29M.
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.
