Hi ray72
To take on that sort of project you will undoubtedly need some form of capital investment to buy the lease - unless you go in as managed tenants in which case you will receive a salary from the brewery and possibly a profit share - although these types of arrangement are getting rarer and rarer.
So far as the IVA is concerned, so long as you can earn enough money to fund your monthly contributions then the Supervisor will not be too worried about your planned career change. Don't forget though, it is far more difficult to manage an IVA when you are self-employed rather than employed and receiving a regular income, and there may be concerns about your abilities particularly if you have not been in the catering trade before.
You will not be able to borrow the funding from a bank, or rack up trade creditors during the period of the IVA, so perhaps you have family members who could help out. It sounds a great dream, but one which is possibly better fulfilled when you have completed your IVA and have no pressure on your finances. As any publican will tell you, be prepared to work 90+ hour weeks as well to make a go of things!
