Membership: Frequently Asked Questions

Check out these questions about the benefits of joining the National Custom and Self Build Association as a member

You want to make self or custom build easier in the UK. You want others to appreciate that self/custom built homes offer the most beneficial and effective way to get the best quality or most cost effective homes. You want the benefits to be available to far more people. You want to have a share of a much bigger national self build industry.

If your company supplies products or services to the sector you need to ensure you are visible to those researching a project. We build about 13,000 homes a year via self or custom build and NaCSBA successfully persuaded government to double this. But despite the legislation, to date this has failed to materialise, although self build is resilient to wider market factors.

Self/custom build is consistently mentioned in reports and policy as an important element of housing provision, and NaCSBA continues to work hard to help self and custom build become mainstream, as it is in so many other countries.

People planning to build their own home trust NaCSBA members with their project, and the more members we have, the more influence we have with government. Plus, the membership fee is excellent value compared to the charges levied by most professional or trade bodies.

Many major suppliers including the leading builders merchants, product companies, kit home suppliers, plant hire businesses, custom build developers, planning and architectural consultants, utility companies, mortgage and warranty providers, specialist magazine and exhibition organisers… the list goes on and on. You can find a list of our current members here.

We already have thousands of would-be self builders who have registered as supporters via the Self Build Portal. In addition we have hundreds of large and small businesses and many trade organisations and public sector bodies – take a look at the Self Build Portal’s Suppliers Directory for a list. Collectively they represent a significant proportion of the people employed in the self build sector.

We do not share the dataset of users of the Self Build Portal due to GDPR, although Gold Partners can contact this list as one of the benefits of this tier of membership. Visit Self Build Portal’s Suppliers Directory for a full list of live NaCSBA members.

There is an Executive Committee that manages the day-to-day activities of NaCSBA, and these meet several times a year. Work is split into a policy team, and a operational team, which each meeting four times a year. All members are invited to our AGM and we hold quarterly member updates. We use e-mail comms and the website to keep members up to date throughout the year.

We only send one or two of our most senior people to such meetings. However, from time to time people like the Department for Communities and Local Government will ask us to field a specialist in a particular area, such as the Bacon Review, in which case we may co-opt a suitably qualified member to represent NaCSBA.

The pandemic, Brexit, inflation and materials and labour shortages have had a serious detrimental affect on the entire construction industry, and we don’t expect self build to increase quickly due to these wider pressures. But our sector is resilient and we are making good progress, and hope soon to see a discernible increase in the sector in the next five years. Membership is vital to support this.


As a member we encourage this, as it demonstrates to your customers that you are a reputable operator. All we ask is that you say above or below the NaCSBA logo that you are a member of the organisation, and do not suggest that we ‘approve’ or ‘endorse’ you in any way. Simply get in touch with our Web/Digital Media team and we can sort this for you.

All members have their logo on their entry on the Self Build Portal and on carousels on the homepage.

Check the ‘Contact us’ page for details. Issues can be discussed at the next Executive Committee, or we may invite you along to meet with us. We are a fairly small group and are happy to talk individually to members; but bear in mind that nearly everyone volunteers their time, so we cannot always be available.

If there’s something you feel passionately about we’d be more than happy to hear from you and get you involved.

Yes; it is thanks to time and effort voluntarily donated by NaCSBA members and leading experts that we have made such good progress already. We are also very grateful for special donations without which larger projects could not happen. Again, visit the ‘Contact us’ page to get in touch.

Membership is for 12 months and we shall contact you with regards to renewal in advance of this date. There is an option for Corporate Gold members to have a 3 year membership deal. Visit our members page for details.
