Cavity Wall Insulation

Cavity wall insulation is one of the most cost-effective home improvements you can make, typically paying for itself within just a few years through reduced heating bills. At Blue Fox Energy and Electrical Services Ltd, we provide professional cavity wall insulation installation that can cut your energy costs by up to 35% whilst improving your property's comfort and EPC rating.

‍

What is Cavity Wall Insulation?

Most homes built between the 1920s and 1990s have cavity walls—two layers of brick or block with a gap (cavity) between them. Originally designed to prevent damp, this cavity can be filled with insulation material to dramatically reduce heat loss. Cavity wall insulation involves injecting specialist insulation into

this gap through small holes drilled from the outside, which are then sealed to match your existing wall finish.

Benefits of Cavity Wall Insulation

Significant Energy Savings: Reduce your heating bills by up to 35% by preventing heat from escaping through your walls. For a typical semi-detached house, this can mean savings of £200-400 per year.

Improved Comfort: Insulated walls maintain more consistent internal temperatures, reducing cold spots and draughts. Your home stays warmer in winter and cooler in summer.

Enhanced EPC Rating: Cavity wall insulation can improve your Energy Performance Certificate rating by one or two bands, increasing your property's value and rental potential.

Environmental Benefits: Lower energy consumption reduces your carbon footprint significantly, contributing to environmental protection and sustainability goals.

Quick Installation: Most properties can be completed in just one day with minimal disruption to your daily routine.

Is Your Property Suitable?

Cavity wall insulation is suitable for most properties built between 1920 and 1990, but not all cavities can be safely filled. We provide free assessments to determine:

Cavity Width: Cavities must be at least 50mm wide for effective insulation installation.

Wall Construction: Assessment of wall materials and construction methods to ensure compatibility.

Exposure Conditions: Properties in exposed locations may not be suitable due to increased risk of damp penetration.

Existing Insulation: Check whether your property already has cavity wall insulation or partial filling.

Damp Conditions: Evaluation of existing damp issues that must be resolved before insulation installation.
