It varies quite a lot. Some bookkeepers charge an hourly rate, which could range from £15 to £40 plus VAT depending on where you are in the UK and how experienced the bookkeeper is. Others will give you a fixed fee so you pay the same each month. This is likely to be based on factors like how many bank transactions and invoices you have each month, how complex your accounts are, and how organised you are when it comes to handing over your paperwork. Each bookkeeper has their own pricing system, so it’s worth getting a few different quotes to see how they compare.
