Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!
Dmitry

How much does it cost to hire an insulation company?
How much you end up spending on cavity wall insulation will depend entirely on the size of your home and the material you select. The most common insulation materials include budget-friendly mineral wool, expanded polystyrene (EPS) beads, and high-performance polyurethane foam. The overall size of your property, ease of access, and where you live in the UK will also have an impact on costs.
The average cost of a cavity wall installation typically ranges between £1,200 for a mid-terrace home and £3,000 to £5,000 for a large detached house.

Factors to consider when choosing a cavity wall insulation specialist
A well-insulated home can entirely transform your living environment, turning it into a cosy, warm space while significantly reducing your winter heating bills. What's more, proper insulation eliminates the stress of rapid heat loss and can add an average of over £11,000 to your property's value by boosting its energy efficiency rating. Investing in cavity wall insulation can also lower your household's carbon footprint and make the property highly appealing to future, eco-conscious buyers.
A cavity wall insulation specialist can help you with:
- Conducting a pre-installation camera survey to check if your cavities are suitable and free of debris.
- Injecting high-quality materials (mineral wool, polystyrene beads, or foam) into the external walls.
- Extracting old, failed, or damp insulation that is causing internal condensation issues.
- Patching and drilling access holes with color-matched mortar to leave a virtually invisible finish.
Insulation specialists don’t just fill walls with foam. They carefully calculate your home’s ventilation needs to prevent dampness, check the structural integrity of your wall ties before starting, and ensure that airflow to existing brick vents or subfloor voids remains entirely unblocked.
Looking after your home's thermal barrier is incredibly important, as poorly installed or degraded insulation can trap moisture against your internal walls, leading to expensive structural damp and mold remediation. If your property is feeling drafty or costing a fortune to heat, an expert can get your insulation back into perfect shape.
Whether you want to install new energy-saving beads or need old, compromised insulation professionally extracted, speak to a specialist today to receive a free quote.
Other insulation FAQs
How long does it take to install cavity wall insulation?
For an average-sized semi-detached UK home, a professional cavity wall insulation installation is surprisingly quick and usually takes between 2 to 5 hours to complete. The installers perform the work entirely from the outside of your property, meaning there is zero disruption to your interior living spaces while they work.
What are the building regulations for cavity wall insulation?
All cavity wall insulation projects in the UK require a building notice to be submitted to a local building control body. A qualified installer will handle this for you, ensuring the chosen material meets the required structural 'U-value' (thermal transmittance standard) to fully comply with current UK building regulations.
How do I prepare for a cavity wall insulation installation?
To prepare for the installer’s visit, clear any vehicles or obstructions from your driveway to grant them easy access to the external walls, move garden furniture away from the house, and ensure any internal areas near the walls are clear so the team can occasionally check interior vents during the drilling process.
