I beg to move,
That leave be given to bring in a Bill to require the Coal Authority to undertake remedial works on properties with subsidence damage as a result of tin mining; to make provision for the Coal Authority to make compensation payments in lieu of such works; and for connected purposes.
The Cornish tin mining industry left many great legacies. In its heyday, it generated extraordinary wealth for our nation. Between the 15th and 18th centuries, there was even a stannary parliament in Cornwall that had the power to veto certain tax proposals coming from central Government. The industry was also a catalyst for great invention and innovation. Richard Trevithick from Camborne invented the first steam locomotive, and William Murdoch from Redruth invented gas lighting—both inventions that shaped our modern world.
There were companies, too, such as Holman’s, which developed extraordinary drilling technology that was exported to mining operations around the world. When the industry declined in the late 19th century, Cornish miners took their expertise around the globe to build mines as far afield as Australia, South Africa, California, Mexico and South America. Today, we still have the world-famous Camborne School of Mines, located with Exeter University at Falmouth, and a new generation of companies is taking that heritage of drilling expertise to the oil and gas industry, and to renewables. There is even some discussion about reopening the last tin mine at South Crofty, as tin prices have recovered.
For those living in Cornwall, however, there is a less welcome legacy from tin mining—the problem of subsidence damage caused by historical mine workings. The subterranean area in Camborne, Pool and Redruth in particular, but also in many parts of Cornwall, is said to resemble a Swiss cheese. It is a complex network of tunnels and mines under the towns in my constituency.
Those mine workings pose several difficult problems for residents. First, there can be significant costs when damage occurs. One of my constituents had to raise a second mortgage on their property to secure £20,000 to put right a mining feature that had opened up in their front garden. Secondly, there is sometimes ambiguity over the liability of insurers. In general cases, insurers help when there is damage directly to a property, although they seldom assist when there are problems arising within the curtilage of a property but not to the structure of the building. They do not generally remedy features to prevent future damage.
The final problem this issue poses for my constituents and others in Cornwall is that there are many cases where people undertake a mining search with a particular company when they buy a property and the company tells them there are no issues, so they purchase a property and secure a mortgage, but often when they want to move and sell their home, they find that a different buyer will use a different mining search company that has different data available to it, and that reveals an issue that can make it difficult for a purchaser to get a mortgage.
