Once you have determined the purpose for which you are processing personal data you must pay the ICO a data protection fee unless you are exempt. If your business uses non-domestic CCTV systems you are likely to need to pay a fee. There are three different tiers of fee and you are expected to pay between £40 and £2,900. The fee depends on the size of your business, your turnover and, in some cases, the type of business you are. If you want to know more, the ICO has published more detailed Guidance on our website .
