Improvement grant

Q: I am one of six GP partners, two of whom own the premises. We are considering applying for an improvement grant that we would mainly use for internal alterations to create more ground floor consulting rooms and move administrative offices upstairs. We are hoping for a grant of 30 to 60 per cent of the cost. Does the residual cost usually fall on the owners of the building or is it shared among the partners? Will there usually be an adjustment to notional rent following the improvements?
