NaCSBA Membership


Help boost the Custom and Self-build sector by becoming a member of NaCSBA.

NaCSBA works to grow the self and custom build market, raising its profile and boosting opportunities for your business. It relies on membership subscriptions from companies and organisations to help fund this core work.

Our financial independence means that we have an objective voice when lobbying, that Government respects. Members can be found on our Membership Directory, which lives on our consumer facing Self Build Portal. This site advises consumers how to self build, and allows them find their local self build registers.

To find out about membership request a call back by using the form.

    Membership options

    We have three levels of membership – Gold Corporate Member, Standard Member and Not-for-profit. Standard Membership has a range of membership options to reflect different organisations.

    *On joining, Standard and Gold members commit to the terms of NaCSBA’s Code of Practice. This works both ways, demonstrating to your customers that you are a trusted operator, and offering consumers peace of mind when sourcing businesses to work on their project.

    Become a Gold Member and show us your full support

    Corporate Gold membership demonstrates that you’re a heavy-weight in the Custom and Self-build sector, and are truly committed to changing the way we do housing in the UK. Your backing is crucial to supporting our lobbying of central and local Government, and contributing to the growth and expansion of the self build industry.

    By partnering with NaCSBA as a Gold Member, you also help us provide better information to would-be Custom/Self-builders – your future customers – and build up our ‘best practice’ information. This enables us to guide future generations of Custom/Self-builders about the most efficient way to build their homes.

    The Benefits

    In return NaCSBA has developed a number of very tangible benefits that will help our Gold Members grow their businesses.

    • The opportunity to send four marketing communications a year to all members of the Self Build Portal* who have agreed to contact from Third Parties. These campaigns are put together by NaCSBA on your behalf in MailChimp, based on your copy and images, with a sign off by you as a Gold Member. (We regret that under GDPR we can no longer share this information with you as data.)
    • Your company will be listed on The Self Build Portal’s Partners page.

    Plus the Standard Member benefits outlined below.

    Special three-year Corporate Gold Membership

    We have a special three-year subscription that offers a significant saving in comparison to annual Gold Membership – saving your company 15% over the cost of three individual years! This saves the hassle of signing up annually and ensures that your company is always recognised as a key player in the Custom and Self Build sector.

    *Most registered users of the Self Build Portal are would-be Custom/Self-builders looking to buy products or services for their future project. Data suggests that those who have registered are: in the detailed preparation stages of getting their projects under way; typically holding budgets of £1-200k each, though many have budgets of over £500k; want to get their project underway in the next two years;  looking for land mainly in the south east/west of the UK.

      Corporate ‘Gold’ Partnership £2,900 annually or £6,900 for three years*

    Notice that VAT will be added to the prices displayed above.

    Standard Memberships

    NaCSBA understand that there are a range of organisations that would benefit from having membership or would like to show their support, but their circumstances vary. Consequently we’ve developed a range of charges for our Standard Membership in an attempt to reflect these differences. Any of these memberships can be classified as Not-for-profit where relevant, meaning the organisation is not signed up to the Code of Practice.
