Certified EWI Pro
Installation.
BBA-Approved System · Precision-Installed
We're a certified EWI Pro installer, which means we only fit their tested system — and we install it exactly the way they specify. The BBA approval behind it belongs to EWI Pro and their products; our certification is what keeps that approval, and your 10-year warranty, valid on your home.
Year Warranty
Manufacturer-backed · issued at completion
EWI Pro's system warranty covers both our services — external wall insulation and silicone render — against delamination, cracking and thermal underperformance, plus our own workmanship guarantee. Qualifying funded schemes carry 25-year cover.
Warranty That Holds
EWI Pro only backs their 10-year guarantee when an approved installer fits the system. Our certification isn't a nice-to-have — it's the condition your warranty depends on.
Trained on Every Stage
Most insulation problems trace back to rushed wall prep or fixings done the wrong way. Certification means we're formally trained on every stage, not just the visible finish.
One Tested System
We install genuine EWI Pro components as the matched system they were tested as, never mixed with cheaper alternatives that can undermine how it performs long-term.
Manufacturer-Registered
As an approved installer, we register your project with EWI Pro and can escalate site-specific technical queries to their team during the install — the process that keeps your warranty valid.

Lower Energy Bills
Lower energy demand turns into real annual savings of £300–£1,000 a year. Self-funded installations typically pay for themselves in 12–20 years — sooner with grant support — then keep saving for the rest of the system's 25–40 year life.
