If and when I get the grant I, will only spend some of it on things that are tax deductable. My van is due a big service and a timing belt (about £1000 to £1300), I usually do most of the servicing myself, but I wouldnt dare do the timing belt. I also have a few little things that need sorting out on other quipment, but I'm going to keep as much as I can of the grant for a rainy day.
With the announcement that this could last beyong this year I'm planning for the worse.
