We have embarked on a programme of change which comes at the end of a 20-year private finance initiative contract. There is both an opportunity and a requirement to review what is needed on the estate. Rents are particularly high in London, and are therefore particularly challenging in the commercial market. We have sought to minimise the effect on claimants, to ensure that there is a good coverage of services within reach, and to run a consultation when a new jobcentre is more than 3 miles away and a journey on public transport takes more than 20 minutes.
