Engineered for Performance
Nexura was founded on a straightforward premise: the UK retrofit industry was producing work that looked good on paper and failed within a decade. We built a different kind of company.
Why Nexura Exists
The UK has a retrofit problem. Not a funding problem, not an awareness problem — a quality problem. Billions of pounds of government money have been spent over the past two decades on insulation programmes that failed because they were installed over damp structures, without adequate vapour control, by contractors whose only incentive was volume.
The result: millions of homes where new cavity fill has absorbed moisture and is now contributing to the wall decay it was supposed to prevent. Millions of homeowners who spent thousands on improvements that made their energy bills marginally better and their walls structurally worse.
Nexura was founded by engineers and surveyors who had spent years inspecting these failures. With a combined experience of over 20 years across retrofit, insulation, roofing, solar, and heat pump installation, our team built this company around a single principle: do it right the first time, or don't do it at all. That principle is reflected in everything: our Building Detox protocol, our independent inspections, our 12-month guarantee, and the fact that we never compete on price with contractors who don't hold themselves to the same standard.
What's Wrong with the UK Retrofit Market
Volume over quality
Many retrofit contractors are incentivised by installation volume, not installation quality. The government schemes that fund much of the industry reward completed measures, not lasting performance outcomes.
Hidden existing conditions
Pre-works surveys are often superficial. The true condition of wall cavities, loft structures, and existing insulation is rarely fully assessed before new materials are installed, burying problems rather than solving them.
Fragmented delivery
Most contractors specialise in one measure. Insulation here. Solar there. Roofing elsewhere. The result is a fragmented set of interventions with no joined-up thinking about how they interact, and no single point of accountability when something goes wrong.
Our Values
Four principles that govern every decision we make, on site and off it.
Precision
We specify to the detail, install to the millimetre, and document to the photograph. Precision is not a marketing word for us. It's the operational standard every job is held to, from initial survey to post-installation inspection.
Transparency
We photograph the condition of your property before we touch it. We document every stage of the work. We have independent inspectors sign off on the finished installation. Transparency is the mechanism through which we hold ourselves accountable.
Performance
EPC ratings are a proxy for performance, not performance itself. We design and install for measurable real-world outcomes: reduced energy consumption, lower bills, improved thermal comfort, and lasting structural integrity.
Independence
We don't take kickbacks from material suppliers. We don't push products on a preferred list. Every specification is made on technical merit, and every installation is checked by an inspector with no financial relationship to the result.

that does it right?
A Precision Assessment is how every Nexura project begins. It takes 90 minutes, it's carried out by a qualified surveyor, and it gives you a genuine picture of your property's retrofit potential and a clear cost plan.
