The Association for Consultancy and Engineering is to warn its members not to sign up to a contract drawn up by client group the British Property Federation.

The Association for Consultancy and Engineering is concerned that the contract drawn up by the BPF would expose its members to unlimited liability and could affect a consultant’s ability to obtain professional indemnity insurance.

A spokesman for the association said the organisation was about to issue “strongly worded” guidance to its members to warn them against signing the contact.

The BPF claims there is nothing in the document that is not being regularly used in the marketplace and that the agreement reflects current practice.
