How can FMB help if things go wrong?

The Federation of Master Builders recognises that on occasions disagreements can occur when building work is being undertaken.

If you have a problem:

Seek advice from the Consumer Advice Helpline on 03454 04 05 06 or visit their website to find out your rights as the FMB cannot offer legal advice.

If you have not already done so write a letter or send an email to the business outlining your dispute and how you wish for it to be resolved.

Template letters can be downloaded for guidance.

If the dispute is not resolved within a reasonable time or you do not receive a response, you may be able to use the FMB Disputes service but we can only provide assistance to consumers providing that the business is a Member. You can use the FMB check a member service.

If your dispute is not with a business that is a Member of FMB, please visit for a list of ADR providers who may be able to help you.

If the business is a member of the FMB:

We offer a free conciliation service (conciliation focuses on what you and the business want and tries to find a way of solving the problem that you are both happy with). However to use our service a consumer (client) must be a private individual who has entered into a contract with a Member and not made a contract in the course of a business ( this includes properties which are let out).

FMB can arrange fixed cost mediation for commercial disputes via CEDR our partner ADR provider. This gives you a quick, cost effective alternative to legal action. Please contact us for further details.

FMB process cannot be considered if:

  • You have not tried to resolve the dispute directly in writing with the Member;
  • The business has ceased to be a Member of the FMB;
  • The work carried out by the Member has been rectified and/or completed by another business;
  • You do not wish the Member to return to site;
  • The dispute is being considered by the courts or is being dealt with by another Alternative Dispute Resolution (ADR) Body;
  • If it is over six years (five years in Scotland) since the building work was carried out by the Member. (Unless the member has provided you with a guarantee which is still valid. We will require a copy with your dispute form.)

FMB cannot offer assistance if you are a neighbour of someone who is having building work carried out and you are unhappy with any disruptions. Speak to the individuals concerned and ask them to liaise with the builder or seek advice from Citizens Advice Consumer Helpline.

FMB will consider disputes if the parties have sought legal advice and/or instructed a solicitor or sought assistance from Trading Standards. We will only decline to assist if the use of these third parties would seriously impair the effectiveness of the service offered to its Members and their clients.

Please note that the FMB is not responsible for paying compensation or making a financial award on behalf of its Members.

Our process will allow the client and Member to work through as follows:

Conciliation by supporting both client and Member (“parties”) to engage and discuss the dispute to agree a negotiated outcome.

A client can withdraw from the dispute process at anytime; our Members are required to follow the FMB’s Dispute service.
