Yes Herts Highways have to do it for us - charge about £1000. TBH the cost isn’t the driving factor here as I’m positive that unless we have to spend LOADS to buy the land or to move utilities etc, the drive will add value to the house. And quality of life as we expect to be here 20 years at least.
The other main stumbling point / headache is that the ground needs to be levelled which means a drop of about 3 foot at the deepest bit. The road is below the house, we have steps to go up to get to our house. So I’d imagine there are all sorts of utilities from the main pipes that go into our homes (I’m thinking gas, electric, water, Virgin), and those may all be underneath the grass bank rather than at road height.
