The show is an annual industry tradition at the NEC in Birmingham. But the size of the exhibition has been shrinking in recent years as Emap struggled to sell space.

The publisher confirmed: “Built Environment Solutions & Technologies (BEST), Interbuild Onsite and Glassex will not run in 2011.”

Two sister shows – InstallerLive and The Infrastructure Show -will continue as planned to run at the NEC in October 2011.

The firm is planning to launch a new show in 2012 with details promised later in the year.

An Emap statement said: “Whilst many leading companies had committed to the BEST proposition in 2011, the economic downturn and unprecedented challenges facing the industry, meant that Emap could not guarantee the scale or scope of event that customers demand and expect.”

One regular visitor told the Enquirer: “I’m not surprised by this – the whole thing has been going downhill for a while.

“The organisers keep trying to reinvent things but the bottom line is that the show is not as successful as it used to be and most visitors are local tyre-kickers who hold little interest for trade exhibitors.”

Richard Baker, MD of Emap Connect’s Construction portfolio said: “We believe this is the right decision at the right time.

“Market conditions are very tough and the industry needs a more targeted event which reflects the challenges of today’s UK construction industry.

“We will now be fully engaging with all parts of the market about plans we have to better serve the construction industry moving forwards.

“We still believe there is a need for a clearly targeted construction show of significant scale in the Midlands, and we will now consult openly with trade associations, potential exhibitors and visitors as to the precise format this should take in 2012.”
