Construction Standards: New Build Homes

Lee Dillon Excerpts

Tuesday 25th March 2025 Westminster Hall

[Mr Lee Dillon (Newbury) (LD)]

It is a pleasure to serve under your chairship, Ms Jardine. I congratulate the hon. Member for Sherwood Forest (Michelle Welsh) on securing this important debate and on her powerful description of the impact on her constituent, Sara, of the 70 remaining defects in her home.

Given that 89% of homeowners are satisfied with the quality of their home, we might think that all is well in the world of house building, but throughout the debate hon. Members have highlighted where it simply does not work for our constituents. Just scratching at the surface clearly shows the different reality beneath, because alongside that satisfaction rate sits the stark statistic that 27% of new homeowners report 16 or more defects in their home. That is not minor snagging; it is a quarter of new homeowners moving into homes that are riddled with problems.

As the hon. Member for Keighley and Ilkley (Robbie Moore) set out, existing homeowners are affected as well. Let us be clear: this is not a new problem. Reports going back as far as the 2007 Callcutt review warned about poor-quality construction and inadequate warranties, yet here we are in 2025, debating the same failures.

My hon. Friend the Member for Mid Sussex (Alison Bennett) pointed out that confidence must be beyond question, but time and again we have seen developers prioritising profit over quality. The consequences can be devastating. Look at Solomon’s Passage in Southwark, completed in 2012 and condemned just six years later due to serious defects. In my Newbury constituency, a new-build estate, Lancaster Park in Hungerford, does not meet the expectations of the people paying a high price to live there. These are not one-offs; these are symptoms of a broken system.

We cannot ignore that the UK has some of the worst-insulated homes in Europe. Six million households in the UK are living in fuel poverty, including 3,000 in my constituency, yet new homes are still built with gas boilers and inadequate insulation. Minister, we cannot keep building homes that are outdated the moment they are finished. The Government had the opportunity to mandate future home standards in the Planning and Infrastructure Bill, but they did not do so.

The Liberal Democrats would change that. Zero carbon must be the default. Every new home should have solar panels and renewable energy as standard. Planning must include climate resilience and flood mitigation, as the hon. Member for Congleton (Mrs Russell) mentioned in reference to section 42 of the Flood and Water Management Act 2010. Retrofitting must be a priority.

The hon. Gentleman talks about all these great ideas for what the Lib Dems will do—fitting solar panels and heat pumps and stuff like that—but does he trust house builders to do that to a high standard?

[Mr Dillon]

I thank the hon. Member for his intervention, which gets to the heart of this debate. Whether it is building a damp-proof course correctly or installing cutting-edge climate technology, the Government have a responsibility to ensure that a strong regulator holds developers to account when they fail. As Members around the Chamber have said, we have seen failure, but that should not prevent us as Members of this House from setting a high bar for developers to reach.

Finally, I shall talk about infrastructure. It is not enough to build houses; we need to build communities, yet too often we see developments spring up without the GP surgeries, schools, public spaces or public transport links that people rely on, or with highways that cannot be adopted, as the hon. Member for Ashfield (Lee Anderson) highlighted. That is why we Liberal Democrats are calling for a planning system that guarantees delivery alongside housing targets. That means mandatory commitments from developers to fund GP practices, schools and green spaces; to put public transport first—new developments should be built around sustainable travel, not car-dependency—and deploy sustainable drainage, with grey water recycling included as standard in all new builds.

Although the Government have taken positive steps, there is still much to do. Those are all things that have been proven possible. Across the country, Liberal Democrat councils have led the way, from zero-carbon homes when we ran York, to 1,300 new council houses in Portsmouth. We know what works. Now the Government must follow our lead. Every family deserves a safe, warm and high-quality home—not just a roof over their heads, but a real foundation for the future. I urge the Minister and the Government to take action. No more delays, no more excuses—just homes that work for the people who live in them.
