About us

The National Custom and Self Build Association (NaCSBA)

NaCSBA is the voice of the Custom and Self-build housing sector. Our mission is to make Custom and Self-build a mainstream choice for everyone seeking a home of their own.

We influence • We educate • We promote

NaCSBA’s objectives

The UK is currently an outlier amongst developed nations with regards to the low level of customer-commissioned new homes that are currently built. Growing our sector increases housing diversification. Custom and Self-build can deliver more and better homes that more people aspire to live in and that communities are happier to see built.

NaCSBA’s websites

NaCSBA’s members’ site

News and information about policy, lobbying and more – for NaCSBA members and professionals operating in the sector. It’s the home to the user preference centre for all three websites, and the Right to Build Portal – the campaign page for anyone wanting to register with their local Self Build Registers.

Self Build Portal

News and information for members of the public, offering advice and support to anyone wanting an owner-commissioned home.

Right to Build Toolkit

The industry-facing website of the Right to Build Task Force, which supports a range of stakeholders and community groups to help bring on more custom build housing by offering tailored advice on a chargeable basis.

Work that NaCSBA does on behalf of its members

Lobbying Government

Promoting and campaigning for its members and anyone working in the Custom, Self-build and community-led housing sector. Ensuring that ministers and officials are aware of the current trends and barriers to growth, and that NaCSBA is feeding into policy across the UK.

Sector research

NaCSBA works to compile statistics and data on the sector, which it uses to support its work, such as its annual Freedom of Information requests to establish how many people have signed up to the Right to Build registers in England.

Working groups

Specific NaCSBA Executive Board members spearhead working groups to look at opportunities and challenges for target sectors, such as Custom Builders or those wanting to build in groups. Their findings help focus our policy targets.

Supporting consumers

NaCSBA’s Self Build Portal website educates consumers, providing an objective source of information and an overview of the sector, offering support and advice to the public.

Creating opportunities for growth

Working alongside the Right to Build Task Force to support more opportunities for owner-commissioned homes to be developed. NaCSBA believes the sector has huge potential to deliver additional homes to alleviate the housing crisis.

Representing member interests

Working nationally and regionally to support and reflect our members’ concerns and successes, ensuring that key decision makers understand the sector and what it needs to deliver.

Right to Build registers

Through the Right to Build Portal we track and support people wanting to sign up to their Right to Build by linking them to their local Self Build Registers.

NaCSBA’s Background

The National Custom & Self Build Association (NaCSBA) was set up by network of companies and individuals with the aim of promoting Self-build and Custom Build as a form of housing delivery that can make a significant contribution to home building in the UK.
This includes community-led housing, such as cohousing or Community Land Trusts, as they are models that lead to owner-commissioned homes.
NaCSBA brings together developers, architects, planners, financial and warranty providers, manufacturers, Self-builders, community groups and local authorities to develop, share and promote best practice in self and custom build.
The Association is run by its members and is independent, relevant and practical, and operated on a not for profit basis. This gives us an objective approach that makes us an organisation that can feed into national and local Government debate.


Launched as National Self Build Association (NaSBA)


Published detailed report about how an increase in self building could stimulate the housing and construction sectors, and the wider economy. Visit the Library to view the documents.


Working with Government, NaCSBA published a detailed Action Plan to promote the growth of the UK self build industry, plus a report about the self build sector in a number of overseas countries. This resulted in Government’s Housing Strategy endorsing and promoting self building as a means of delivering volume housing for the first time.


At the request of the Minister for Housing and Local Government, NaCSBA produces a progress report on the implementation of the Action Plan to promote the growth of self build housing


NaSBA becomes NaCSBA – the National Custom & Self Build Association to reflect the new and growing custom build world sector.


Digitising Custom Build campaign is launched, to look into new digital tools for the sector. NaCSBA organises a summit at No. 10 Downing Street with Housing and Planning Minister Brandon Lewis.


The Right to Build Legislation comes into effect in April 2016, with an ambition to create 20,000 per year by 2020. By October 2016 the first returns show that 18,000 have signed up to the registers to have input into building their own home, as announced by then Housing Minister Gavin Barwell – click here for his video.


The Right to Build Task Force, a NaCSBA initiative, is launched, and NaCSBA’s work is supported in the Housing White Paper: Fixing our Broken Housing Market. NaCSBA works with Welsh Assembly and Scottish Government to promote Custom and Self-building on a policy level.


Following submissions from NaCSBA, the new National Planning Policy Framework acknowledges that Custom and Self-build housing can contribute to affordable in terms of homes delivery.
