what type of accountant would people recomend to use for a window cleaning business?
One with a good oven.
okay, gas or electric? what about trouser waist size? does this matter much or should i be more intersted in the colour of the socks he wears on wednesdays? 
thanks in advance for the sarky response! 
but any real answers welcome! 
OK. The serious reply this time

I'm sure you wouldn't want your books burned to a crisp anyway.
I'm a sole trader.
The accountant I have is reasonably priced (c. £250 a year) but I do make it pretty easy for him.
He is not chartered.
At the last count, he had never had any run-ins with HMRC.
I've been a loyal customer and been with him since I started (20 years). What I'm saying here is that if you find one that seems OK, stick with him/her.
Also, I know from our conversations that he would be fine about doing a payroll and VAT returns, and would have no problem with any expansion of my business - if I ever decide to go in that direction.
He's OK about me picking his brains on some issues though I imagine that if I took up loads of his time he would want to charge for this (no problem with that).
If there are any odd looking items in the expenditure list, he asks me about them rather than just deleting. I never put anything in there unless I can reasonably regard it (or a proportion of it) as a business expense anyway. By odd items that may be a bit unusual I mean things like sunglasses (safety device due to looking up more with WFP), a heater and duvet (to avoid water freeze-ups), key cutting, bicycle pump (for trolley tyres), fee to be weighed on weighbridge (I needed to check how much water I could put in the tank when I first got the van) etc etc. So long as I can show that it is for work he is fine with it.
So ask the accountant questions based on where you think you might want to go with this business.
Chartered will usually cost a lot more but is probably unnecessary. It used to be that if you were a limited company you had to go chartered. I believe that this was changed a few years ago though.
