Aim of this survey

The Monthly Business Survey (MBS) is a survey of businesses within the construction and allied trades sector in Great Britain. The survey collects information about the value of new work and repair and maintenance, for both housing and non-housing projects carried out during the month and information about employment quarterly.

The results are used to monitor the performance of the industry and contribute to the calculation of gross domestic product (GDP). GDP is a key economic measure used by the Bank of England and HM Treasury to monitor and forecast economic growth and to inform vital policy decisions.

Results also contribute to a monthly Eurostat release on European construction, allowing international comparisons of industry activity.

What you need to know

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

  • housing work

  • infrastructure

  • non-housing work, excluding infrastructure

  • total value of work

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 MBS 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 plus employees) for any relevant ONS business surveys because their information is so significant.

We select some small and medium businesses, usually for a set period of time 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.

How to complete this survey

Please complete and return the questionnaire following the guidelines on the front page.

Reminders are issued automatically, so you may receive one if you submit data just before or after the return date.

At the moment this survey is not available to complete online. We are currently developing a secure online collection platform. You will receive a letter notifying you when you can complete the MBS on our new platform. We appreciate your patience.
