Land contamination costs homeowners £11.5bn

Given that there are 25.6 million separate dwellings in the UK , this means 768,000 properties could be affected.

The average cost of cleaning up contaminated land is £250,000 per acre, meaning making right the average contaminated plot in the UK would cost £15,000. 

The Environmental Protection Act states that while the first person to bear responsibility for cleaning up of contaminated land is the person who caused it, where that person cannot be identified by a local authority, the person who currently owns or occupies the land will be held responsible for removing the contamination.
