Aim of this survey

The Annual Survey of Goods and Services (ASGS) is used to measure turnover generated by UK businesses. In particular, it measures the turnover broken down into the different goods and services from which it is generated, both inside the UK and outside the UK. Data from this survey will be used within the Services Producer Price Index (SPPI) and national accounts in their calculation of gross domestic product (GDP), which are both important economic indicators.

The ASGS is being conducted in partnership with IFF Research. If you have been selected for other ONS surveys that are currently collected online, please be aware the appearance and functionality of the ASGS questionnaire will be different.

What you need to know

To complete the survey, you will need the following information:

  • turnover broken down by each of the services and goods the business provides, for customers inside the UK and customers overseas

All information you provide is strictly confidential.

Why you were selected

Your business has been selected from a directory of businesses in the UK, which are registered for VAT and/or PAYE or with Companies House. Your response ensures we represent your industry.

The ASGS is conducted under the provisions of the Statistics of Trade Act 1947. Once selected, your business is legally obliged to comply. You cannot appeal your selection.

Why you have received this survey

We survey businesses of all sizes to ensure our statistics are representative of the UK economy. We select large businesses (those with 100 and over employees) for any relevant Office for National Statistics (ONS) business surveys because their information is so significant.

We select some small and medium businesses, usually for a set period then replace them with other businesses from their industry. They are very important to us as their trading patterns are often very different to large businesses.
