Drainage investigations resulted in over 80% of the site draining to a natural watercourse.  Our findings were submitted to the water company and the first offer was a refund of £8,000.  Intense negotiations resulted in a refund of £255,442.

The client is now enjoying the ongoing benefit of a £40,615 per annum saving on their surface water drainage charges.  This is the third largest refund we have organised and the largest for a direct customer.  Over £10,000,000 in surface water drainage refunds to date
