Market data

As a benefit of membership the BMF provides a wide range of statistical business reports for members.  

Builders Merchant Building Index (BMBI) and Sales Indicators Report


The Builders Merchant Building Index (BMBI) is a brand of the Builders Merchants Federation. Launched and managed by MRA Marketing, it uses sales-out data from GfK’s General Builders’ Merchants Panel and includes a panel of leading industry Experts who speak for and explain their markets. For more information scroll down and click on the relevant links.

This BMBI uses data from GfK’s ground-breaking Builders Merchants Panel, which analyses data from over 80% of generalist builders’ merchants’ sales throughout Great Britain.

CMA Best Product Launch Award 2017GfK’s Builders Merchants Panel started collecting data in July 2014, and all trend data in the BMBI is indexed on the 12 month period July 2014 to June 2015. The monthly series tracks what is happening in the market month by month and includes an in-depth review every quarter. This trend series gives our industry access to far more accurate and comprehensive data than that available to other construction sectors.

The reports also include views from our panel of leading industry experts to help explain trends, issues and opportunities in their markets.

The BMBI is sent out to all our members every month as a benefit of membership. The report combines data from GfK’s ground-breaking Builders Merchant Panel, which analyses data from over 80% of generalist builders merchants’ sales throughout the UK, and the BMF’s own Sales Indicators based on monthly returns from the majority of merchant members outlets. It gives our industry access to far more comprehensive data than that available to other construction sectors. 

There are two tiers of report available to members, depending on the level of regional sales data members wish to receive from the BMF Sales Indicators-see text below. BMF Sales Indicator report now features alongside the BMBI. All members of the BMF can receive the core BMBI report. However those members who have paid the subscription fee will also receive full insights from the BMF Sales Indicators. The core version still includes a general overview of each month's regional sales findings. Alternatively, merchant members can contribute their monthly sales figures which will be included anonymously into the Sales Indicator report, to receive the full version for no added cost. If you are interested in receiving the Full Report including Sales Indicators or believe they have been sent the wrong version please contact Richard Ellithorne by email at

Sales Indicators - new format for 2018

The BMF Sales Indicators are compiled every month from sales turnover information from the majority of merchant members’ outlets. Builders Merchant sales nationally are adjusted for both price inflation and trading days. The Sales Indicator Report is sent out monthly to members who either pay for the service or regularly contribute. If you would like to contribute, and therefore receive the report for free, then please contact Richard Ellithorne at If your company does not wish to contribute, but would like to continue to receive the Sales Indicators, then you would have to subscribe for a 12 month subscription and again contact Richard Ellithorne for more details. 

BMF and Phocas (a BMF Service Member) have teamed up to introduce a brand new look BMF Sales Indicators, bringing with it greater analytics and functionality. The new service launched in January 2018. For the time being please continue to send your monthly submissions in the same format. There is a taster video (right) to highlight some of the features and analytics on offer.

Moving away from the excel spreadsheet, data will be submitted into an online area. These changes will bring a more consistent sample size, be far less onerous and greatly reduce any time spent inputting the data - 36 input fields for regions will be reduced to just 6. You will see a much more visually-orientated dashboard - some samples of which can be seen in the video (right).

In order for you to receive these reports you will need only change the way in which you input figures. An online member area will be the portal for data submission and also the area you can view the monthly findings. With this electronic format there will be greater manipulation of figures available. For example, user defined periods of comparison can be chosen. There will also be greater functionality in displaying the data which will provide more sophisticated analysis.

Remuneration survey

We are very grateful for all of the 190 responses that we received for this year's Report (which is an increase of 43% on last year).

This year we have included new questions on male-female employment ratio, staff retained as a % over last year and the number of apprentices employed. 

The Report shows salaries, wages paid and benefits given to merchant members' staff as at 1 April 2018, for each of the thirteen UK Standard Planning Regions and nationally.
