What is a SIC code?

Companies House requires every limited company to identify its business activities by industry and sector using at least one SIC code (maximum of 4) which stands for Standard Industrial Classification of economic activities. It's important to get your code right otherwise you are likely to experience problems opening bank accounts or obtaining a mortgage. The SIC codes used by businesses in the property sector are:
