This part of Cornwall has a unique mining heritage. Redruth was once one of the wealthiest towns in the country and we exported mining expertise across the globe with our ancestors travelling as far afield as Cape Town, Real Del Monte in Mexico, New Zealand, Australia and Wisconsin in the United States. Inventors such as Richard Trevithick and William Murdoch put Cornwall on the map as a leading centre for industry and innovation and we are lucky to have such a rich legacy that has been left to us.
Today that legacy means that we have World Heritage Site status and the many old engine houses around our towns are iconic. However, there is another legacy which periodically causes major problems to some residents. The ground beneath the whole Camborne, Pool and Redruth area is like a Swiss cheese with mine workings going back centuries. Many of the more recent features were mapped and are known about but others that go back further are sometimes not mapped.
Over time, I have had a steady stream of constituents contact me with problems of unexpected subsidence that leaves them with huge personal costs. Sometimes people have had a mining survey completed when they purchased their house which gives a clean bill of health but when they come to sell and move on, they find that potential purchases using a different mining security company offer a different, adverse opinion which leaves them stuck.
For many property owners, they are also hamstrung by the fact that many insurers will not include mining subsidence in their cover unless it actually threatens the house itself. On other occasions certain sites have experienced local subsidence which upon investigation have identified untreated old workings. For instance, at Clijah Croft in Redruth, localised depressions have led to the identification of 17 areas on the site which require attention due to old mine workings being present. Whilst at Grenville Gardens in Camborne, untreated old mine works have led to the council having to excavate the area to stabilise the ground before relaying it all.
In a bid to tackle the problems presented by these legacies, this week I presented a Bill to Parliament that would introduce new financial assistance to help home owners in Cornwall whose properties are affected by subsidence damage as a result of historic tin mining features. My Bill would amend the Coal Mining Subsidence Act of1991 in order to create an additional obligation on the Coal Authority to offer financial and other assistance to help home owners whose property has been affected by subsidence damage due to tin mining. Currently, those living in former coal mining areas whose properties are affected by subsidence damage are entitled to financial support to put right any damage. Due to an oversight in the drafting of the original legislation, similarly affected communities in former tin mining areas like Camborne and Redruth are denied the same sort of compensation or assistance.
Cornwall’s tin mining industry left an enormous legacy to the world in terms of the wealth it created for our country during the industrial revolution, the spirit of invention and innovation that went with it and the mining expertise that was subsequently taken around the world. But for many, the threat of subsidence damage to their property from historic mining features is a constant worry and it is time to finally address this gap in the law so that Cornwall is treated equally and receives the support it requires.
