The Race to Net Zero – But at What Cost?
The UK’s drive towards net zero has accelerated in recent years, with government schemes promoting retrofitting (retrofit) and home insulation to reduce carbon emissions and ease the burden of rising energy costs. But while the vision is the right one, the execution hasn’t always lived up to expectations.
A recent article from PoliticsHome rightly highlighted a growing problem: too many homes are being retrofitted poorly or incompletely, often by companies that prioritise profit over quality. The result? Draughty homes, disappointed homeowners, and a loss of trust in the entire industry.
This is where experience makes all the difference.
Westville: A Family-Run Business with 37 Years of Proven Quality

At Westville, retrofitting isn’t just about ticking boxes – it’s about doing the job properly, with care, professionalism, and attention to detail. For over 37 years, we’ve been helping homeowners, housing associations, and commercial property owners make their buildings warmer, more efficient, and more sustainable.
As a family-run business, we pride ourselves on maintaining high standards, offering expert advice, and carrying out every job with the kind of precision and accountability that’s often missing from large national contractors or pop-up providers. When you work with Westville, you’re not just another project – you’re part of a legacy built on trust and results.
Why Retrofitting is Still Crucial – And Needs to Be Done Right
The concept of retrofitting remains one of the most impactful ways to tackle the UK’s energy crisis and support the journey to net zero. From cavity wall insulation and loft insulation to advanced external wall systems and ventilation upgrades, every retrofit measure helps reduce heat loss and lower energy bills.
However, as PoliticsHome points out, retrofitting gone wrong can do more harm than good. Incomplete or shoddy insulation work can lead to damp, mould, and even long-term structural issues. That’s why choosing a reliable partner is so important.
A Track Record of Delivering Retrofit Success
Westville has a long-standing reputation for delivering high-quality retrofit work, particularly in social housing and publicly funded schemes. We work closely with local councils, housing developers, and individual homeowners to ensure every project meets building regulations, energy efficiency targets, and the expectations of the people who live there.
We don’t cut corners. We don’t outsource to unqualified teams. And we never leave a job half done.
Every member of our team is trained, accredited, and committed to excellence – which is why we’re still here after nearly four decades, growing steadily and maintaining the same family values we started with.
Supporting the Local Economy and Future-Proofing Homes
Retrofitting not only helps the environment – it also boosts the economy by creating jobs, upskilling local workers, and improving the housing stock. As a proud employer in the Midlands, we’re deeply embedded in our local communities, and we believe that long-term success comes from investing in people as much as in property.
With energy bills still high and government incentives for energy efficiency increasing, there’s never been a better time to retrofit your home or building. But it’s essential to choose a company with the experience, ethics, and craftsmanship to do it right.
Choose Westville – The Name You Can Trust for Retrofit and Insulation
If you’re considering energy efficiency upgrades for your home or building, don’t gamble on a newcomer or a company offering quick fixes. Choose a partner with a proven track record, a family-run ethos, and a genuine commitment to quality.
