The NFB Membership Standard

Membership of the National Federation of Builders stands as a mark of excellence for those construction companies who carry the badge. NFB membership is not open to all – construction companies must first meet the application criteria and pass our vetting procedures. To join, potential members must also sign-up to our code of conduct and then adhere to it for the duration of their membership.

We know that over throughout our 120-year history, construction clients, whether new or experienced, big or small, have relied on the NFB badge as the sign of a professional contractor. To ensure clients can continue to have faith in the NFB brand and its membership, we aim to be as transparent as possible in showing what being an NFB member means in practice.

  • NFB Members must:
  • Commit to upholding the highest standards of practice
  • Undertake business with integrity
  • Use properly costed schedules and standard contracts
  • Apply nationally recognised minimum pay rates or above
  • Always maintain public liability and employer’s liability insurances
  • Work with minimal disturbance to the public
  • Ensure health and safety standards and awareness
  • Work with the construction supply chain in accordance with good practice
  • Be accountable to the NFB complaints procedure

What can I expect from an NFB member construction company?

Members of the NFB are subject to a comprehensive code of conduct as well as the UK construction industry competition code of conduct available here. NFB members are also subject to the NFB complaint’s procedure which you can find here.

What does a construction company need to do in order to be admitted to the NFB?

Construction companies must provide comprehensive information before they qualify for NFB membership, this includes:

  • Business address
  • Business status
  • Number of years trading
  • Details of Directors and Company Secretary / Partner or Proprietor
  • Details of all trading offices
  • Company registration number
  • Public liability Insurance details
  • Construction Skills Registration Number

  • Stakeholder pension scheme
  • Numbers of employed – Direct and LOSC
  • Evidence of high trading standards via the provision of references from clients, professionals and/or accountants

Are there any other NFB standards, other than membership?

As well as NFB membership standards which are the bedrock of our offering, the NFB also awards the NFB future Net Zero standard and the NFB Heritage Approved Contractor Mark – both of which are only available to NFB members.

The NFB future Net Zero standard is an independently verified accreditation that recognises that the member measures their business’ carbon emissions. The mark is awarded at four different levels, depending on the level of carbon emission reductions that the member has managed to achieve. You can find out more about the standard here.

The Heritage Approved Contractor Mark is an NFB-awarded mark that helps to prove the organisational capability of an NFB member to deliver heritage and traditional building projects. The Mark is awarded based on the member meeting seven key criteria which includes previous heritage work and a commitment to heritage specialist project management and tradespeople/subcontractors. You can find out more about the mark here.
