Expert External Wall Insulation Installation | Boost Energy Efficiency, Reduce Heat Loss & Enhance Your Property’s Appearance
In today’s energy-conscious world, external insulation is one of the most effective ways to improve a building’s thermal performance, reduce heating costs, and enhance its visual appeal. Whether you’re a homeowner in Perivale, a property manager, or overseeing a commercial development, investing in high-quality external house insulation delivers long-term comfort, energy savings, and increased property value.
At our London-based insulation company, we specialize in professional external insulation UK solutions to both residential and commercial buildings. Our expert team delivers certified external wall insulation (EWI) systems that meet strict UK building regulations, including compliance for retrofit projects. From initial survey to final render, we ensure a seamless, clean, and durable installation.

External insulation, also known as external wall insulation, involves applying a layer of insulating material to the outside of a building’s walls, followed by a weather-resistant render or external insulation cladding finish. This method is highly effective at eliminating cold spots, reducing heat loss, and preventing damp and condensation.
Unlike internal wall insulation (or wall insulation internal), which takes up interior space and requires redecorating, external insulation preserves floor area and transforms the exterior of your property. It’s ideal for solid-wall homes common in older properties across Perivale and West London — that lack cavity walls and are prone to heat loss.

Dramatically Improved Energy Efficiency.Up to 70% of the heat in an uninsulated home escapes through the walls. With external insulation, you can significantly reduce this loss, leading to lower energy bills and a more comfortable indoor climate year-round.Enhanced Aesthetic Appeal.Outdated or damaged brickwork can be covered with modern, attractive finishes — from smooth to textured renders in a range of colours. This instantly upgrades your home’s curb appeal.Long-Term Durability.High-performance EWI systems are designed to last 25–30 years with minimal maintenance. They are weatherproof, impact-resistant, and UV-stable.Reduced Damp & Condensation.By keeping the structural wall warm, external insulation prevents interstitial condensation and damp penetration common issues in older homes in areas like Perivale.Improved EPC Rating.Homes with wall insulation often see a 20–40 point increase in their Energy Performance Certificate (EPC) rating, making them more attractive to buyers and compliant with rental standards.Noise Reduction.The insulation layer also acts as a sound barrier, reducing external noise — especially beneficial in busy urban areas.
In Perivale, many homes were built in the mid-20th century with solid brick walls and little to no insulation. As energy prices rise and environmental standards tighten, residents are turning to external house insulation as a smart, future-proof solution.
Our team has completed numerous external insulation projects in Perivale, Greenford, and Ealing, helping homeowners.
We work closely with local councils, housing associations, and private homeowners to deliver PAS 2035-compliant upgrades that qualify for green finance schemes and meet social housing retrofit standards.

Free On-Site Survey
We assess your property’s structure, existing wall type, and insulation needs.Design & Specification.Choose from a range of insulation materials (e.g., mineral wool, EPS, phenolic) and finishes (silicone, acrylic, or monocouche render).
Professional Installation
Our certified installers fix insulation boards to the external walls, seal joints, install reinforcing mesh, and apply the final render or external insulation cladding.
Final Inspection & Handover
We clean the site thoroughly and provide documentation, warranty (up to 25 years), and maintenance advice.
The entire process typically takes 1–3 weeks, with minimal disruption to your daily life.
While internal wall insulation (or interior insulation) is an option, it comes with significant drawbacks:
Reduces room size
Requires removal of skirting, sockets, and fixtures
Risk of condensation behind the insulation
Disruptive and messy installation
In contrast, external insulation keeps your interior untouched, improves the building envelope more effectively, and adds long-term value. For most solid-wall properties — especially in Perivale — external wall insulation is the superior choice.
That said, internal wall insulation may be suitable for listed buildings or where external changes are restricted. We offer assessments to help you decide the best solution.
