Lot's of very useful advice!

Agree'd with the family thing, sister borrowed couple of grand off my brother when a loan was taken out and then not needed but they had used a small amount to buy a car. Borrowed couple of grand to pay the loan back within 14days so didn't cost anything. Then her husband lost his job. No tension really at all other then the feeling that I'd hate.
Don't want to borrow any more than I can afford ever until obviously a mortgage. AFAIK you need three years books when self employed? So will need to start properly from April.
Phone bill is a start and thinking of Tesco credit card, 3% on food and fuel and I get through stacks of fuel.
Big learning curve and huge headaches I can see in the near future with tax, paperwork etc.

Really appreciate the advice though! Some really useful stuff.
Got another window cleaning round today, just got rid of all of mine and saw this one and got it. Not owned by me but I rent it. Perfect as less hassle, I get x amount a month from it minus contingencies and it's local. Plus 5 days a month and 600-800 quids worth. Plus as it's not owned by me if I can't do it there's other people to do it.
Thought this was a good idea as it's regular money coming in for the quiet months.
Going to try and book a meeting with a business advisor, got some cash saved but no real trail to it as the last years been a bit messy!
