Consumer survey 2023

The National Self Build and Renovation Centre (NSBRC) has released an infographic sharing the data from its 2023 consumer aspirations survey, which finds that three quarters of self builders are over 55.

The research, which is conducted in association with the National Custom and Self Build Association (NaCSBA), is the third annual survey of those interested in self building, made up of users of NaCSBA’s Self Build Portal or visitors to the NSBRC in Swindon. This resulted in the survey capturing the opinions and actions of 759 responses, giving weight to the data.

In line with the sentiments expressed in previous surveys, the data showed that over 90% said they would not buy a new, spec-built home, while over 90% also said that sustainability, including micro-renewables, was a major consideration for them. 


Significant findings

Average ages

Most self builders are between 55-64, with just 1 in 10 under 45. This older age profile has risen slightly over the last three years, but NaCSBA continues to lobby for more opportunities for younger self builders, such as more small sites. 

Finance & age

While the average joint household income is £67,000, many people build with lower household incomes, but this is often because they are retired.

Only 40% of respondees said they worked full time.

New builds

NaCSBA welcomes the fact that over two thirds of resondees successfully found land to build a brand new house. 

Of those who are self building, self-managed is the most common route, with 40% opting to get stuck in. 

Total budgets

The spend for plot and build is up, on average ranging between £350,000-500,000. This has gradually been creeping up, in line with other costs going up across the board.


Two-thirds of respondees are using, or plan to use, savings to fund their project. This is typically made up of personal savings and the equity in their existing property. 

Build methods

Timber frame remains the most popular choice of build method for self builders, at 24%, with SIPs/prefabricated systems closely following at 23%. Brick and block was 14%.

The Right to Build

There is good news that 4 out of 5 people had heard of the Right to Build legislation and the registers, as previous surveys showed less awareness. Just over half of respondees had signed a local self build register, which remains a vital part of every self builder’s journey.

Signing might not get you the plot you want, but it ensures the council knows you want to build and it has a statutory duty to consider this when carrying out its housing and planning work. NaCSBA encourages everyone considering a project to sign up to their Right to Build. For FAQs about the registers click the link below.
