Prince Charles is set to return to the flood-hit village of Muchelney in Somerset.
The visit comes five months after the Prince of Wales saw the impact of flooding on agriculture and the livelihoods of people on the Somerset Levels.
The Prince used the emergency boat service - the only means of travelling in and out of Muchelney at the time - and a tractor to meet people in their own homes.
He also criticised efforts to help those affected by the floods, saying: "The tragedy is that nothing happened for so long."
Almost 1,000 businesses have received payouts from their local councils as part of the Government's package to help them recover from the winter flooding.
In a written parliamentary answer, local government minister Brandon Lewis confirmed 979 companies benefited from the Business Rates Relief Fund as of the beginning of June.
There are no set or advance allocations to councils, which instead have to retrospectively claim back the cost of the relief.
Mr Lewis said 66 local authorities had submitted claims for reimbursement ahead of the deadline last month and added the Government expected to pay back £4 million shortly.
The environment minister Dan Rogerson said Government spending on flood defences has protected "1.4 million properties" from flooding.
Speaking on Good Morning Britain, Mr Rogerson justified the spending levels after an extra £270m was used in Somerset due to the "wettest winter on record."
