About Rockwarm
Family-run. Midlands-based. Transforming homes since 1985.
Rockwarm started in 1985 with a simple belief: homes with proper insulation are warmer, more comfortable, and cheaper to run. Four decades later, that is still what drives us.
We have grown from a small local operation into one of the Midlands' most trusted insulation specialists, working on everything from Victorian terraces in Coventry to 1930s semis in Nuneaton and post-war homes across Birmingham and beyond.
Why we're different
Built on trust, not pressure
People invite Rockwarm into their homes when they want clear advice, reliable workmanship, and a team that treats the job properly from survey to finish. We focus on honest recommendations, good communication, and work we would be happy to stand behind on our own homes.
We use better materials
We use Rockwool insulation and K Rend silicone render because they perform properly on the kinds of homes we work on.
We're not salespeople
No pressure, no hard close, and no “today only” tactics. We explain the options, answer your questions, and let you decide in your own time.
We're actually local
Based in Nuneaton, we serve Coventry, Birmingham, Warwickshire, and the wider Midlands as a genuine local business.
We do our own work
We handle all aspects of our projects in-house, ensuring quality and consistency from start to finish.
Our Services
Insulation designed around real homes
We are external wall insulation specialists, helping homeowners improve warmth, energy performance, and kerb appeal with properly specified systems and practical advice.
External Wall
Insulation
Our signature service for solid-wall and hard-to-heat homes. It reduces heat loss, tackles condensation, and transforms the outside of the property at the same time.
Cavity Wall
Insulation
A fast, cost-effective solution for suitable cavity-wall properties. Ideal when you want a practical thermal upgrade without changing the appearance of the house.
Loft
Insulation
Often the quickest win for energy savings. A straightforward way to stop heat escaping through the roof and improve comfort throughout the home.
The people behind Rockwarm
A local team that sees the job through properly
Our team includes experienced surveyors, customer liaison staff who keep you informed throughout the project, and skilled installers who take pride in the standard of the finish.
When you call Rockwarm, you speak to real people who know the business and care about getting things right. When our team arrives at your property, they are our employees, not subcontractors.
- Experienced surveyors

- Customer liaison support
- Our office team keeps customers informed throughout the job so nothing feels unclear or left hanging.
- Directly employed installers
- The people doing the work are part of Rockwarm and take pride in the finish they leave behind.
How we work
Survey first
Every property is different, so we start with a proper survey rather than guessing from photos or a quick phone call.
Honest assessment
If external wall insulation is not the right answer for your home, we will tell you plainly.
Clear communication
You know what is happening, who is arriving, and where the project stands throughout the process.
Quality materials
We specify Rockwool insulation and K Rend silicone render because they suit the homes we work on and the standards we want to maintain.
Proper aftercare
We are still here after the work is complete, and our guarantees mean something because we stand behind the job.
