Construction minister Nick Raynsford is today due to publish an interim report from the taskforce he set up to help outlaw cowboy builders.

The taskforce, headed by Stent Foundations chairman Tony Merricks, has called for the introduction of a Quality Mark to differentiate between reputable builders and cowboys.

Raynsford is expected to launch a three-month consultation on the paper today, with a raft of anti-cowboy measures to be introduced in summer 2000.

He is expected to ask the industry who it believes should administer the Quality Mark.

A new joint body, including consumer, Office of Fair Trading and industry representatives, could be set up to ensure that all parties are satisfied with the decision.

But there are fears that whoever administers the Quality Mark may be asked to pay the first £100 towards any compensation a builder with the mark has to pay if it carries out shoddy work.

A six-month pilot scheme for the Quality Mark is to be set up in Birmingham, although Raynsford is not expected to go into any detail about this.

The controversial idea that workers at firms with the Quality Mark should be tested to see if they meet "competent operative" requirements has been given less prominence after it attracted strong opposition.
