Another interesting thread. Basically talking about expenses in £ is pointless. Who is doing better, someone spending £10,000 on overheads on a turnover of £100,000, or someone spending £2,000 on a turnover of £10,000?
You need to focus on gross margin and net profit - of each £100 of turnover what % is profit? Don't kid yourself either - overheads are everything that you spend on the business, from wiper blades to that £2 pack of paper for the printer to a new sack of resin. Add up all your overheads (as an example let's say £5650) and subtract from your turnover (say £36000) to get your net profit (£30350). Divide your net profit (£30350) by your turnover (£36000) to get your gross margin as a % figure - in this case it's 84.3%. Your gross margin figure should be going up every year, ideally as a result of decreasing overheads AND increasing turnover. You need to monitor these figures and strive to improve both.
The above should roughly work for most sole traders who don't have any big capital expenditure planned or current, employ or work on an accrual system. Those new to business should also remember:
1. You are "taxed on what you make, not what you take", i.e. you are taxed on profit, not on drawings (the money you take out every month to live on). Your net profit is basically what an employed person's gross annual salary is - i.e. before tax and NI are taken out.
2. Remember the dreaded tax paid "on-account" when you are past your first year and are in profit...:

It's a business expense and only tax deductable, not free. The way to think of it is the cost price to you as an individual is actually around 25% less than you pay at the till.
4. A cashflow is essential - I have a rolling 5 year cashflow that identifies expenses (as much as possible) before they happen.
5. Don't forget Class 4 NI has to be paid, not just tax.
6. An accountant can make your life a lot easier - it's a cost, sure, but it's also less of a ballsache. Just keep a careful record of your takings (window cleaning software does this for you - I use Roundtracker) and keep your receipts in date order and don't hand him a carrier bag full of loose ones - you'll just pay for him to sort them.
Personally speaking with the spreadsheets I have set up I know what my net profit is projected to be as the year progresses, based on what I've taken so far and what I project to come in / go out. I am in the fortunate position to not need to take out everything that i've made (i.e. net profit for the month minus an amount put aside for tax and NI) each month, then twice a year I pay myself a little "bonus", still leaving enough in my business bank account for problems such as a really bad winter, illness, my van needing major work. This way tax and NI is accounted for, the business account has enough working capital, and I get paid what I'm due. It works for me, but I'm not a family man with a mortgage and kids, so I appreciate it might be different for others.
