On April 1st 2017,across the UK all B1 use properties are being revalued and the new rates that will be payable are likely to fill the occupiers with dread. Once revalued, the rates are expected to jump to just under two thirds of rents – so on top of high rents they can expect to pay an extra 60% on rates and for many this might not be possible. In London’s City market, this could amount to an additional £20 per square foot and £23 per square foot in the West End.
