The NABC expects high standards of professionalism from our members as set out in our Code of Practice. We recognise that very occasionally a member may breach this Code. If you feel that one of our members has breached the Code and wish to make a formal complaint, all complaints received are dealt with in accordance with the following procedure.

The NABC's legal authority

The NABC is a voluntary membership body, not a government regulator. As such we only have authority over our members in relation to their membership with us. We have no authority to issue fines, compel a member to start or to complete a project or prevent a member from trading.

Making a complaint about an NABC Trade Member

NABC can help customers who have a dispute with an NABC member company with a free service whereby we will endeavour to reconcile a dissatisfied consumer with the member company. A consumer is defined as an individual who has entered into a contract with a member.

Prior to submitting a complaint to the NABC, we would ask that consumers who have concerns regarding the building works carried out under contract with a NABC member to initially contact the member and utilise their complaints policy to express these concerns and agree a resolution. All NABC members are required to have their own Customer Complaints procedure.

The following are examples of areas where the NABC is not able to assist:

  • We are unable to assist if the company has ceased to be a member of NABC
  • We are not responsible for paying compensation or making a financial award
  • We cannot become involved if either party has commenced legal proceedings or employed/involved a third party to resolve the dispute for example a Solicitor, Trading Standards or another trade body.
  • Complaints need to be submitted by those in the contractual relationship with our member (the consumer), or by the member themselves.
  • Where the work in question has been carried out more than four years ago

Where the work in question has been carried out outside of the UK

What can NABC do?

Upon receipt of your initial complaint to our Helpdesk (, a member of our team will advise your local partner manager, who will contact you to discuss the matter in more detail and seek resolution between both parties. If the matter requires further attention, we may request that you make an official complaint in writing, following our complaints procedure. Our Partner Managers will always attempt mediation between both parties prior to an official complaint being issued.
If no resolution can be achieved, we can refer the parties to consider independent adjudication.
The NABC monitors the conduct of its members and members are expected to adhere to the NABC’s Code of Practice. We can, if appropriate, refer the Member’s conduct to the NABC’s complaints team for consideration for breaches of our regulations and Code of Practice. This is an internal matter between the NABC and its member. Please note that NABC will only liaise with ONE main contact regarding your dispute.
All complaints to NABC will be dealt with in line with the NABC complaints policy.
