Frequently Asked Questions


With proper installation and maintenance, external wall rendering typically lasts 20-30 years, while insulation can last the lifetime of the building. Our systems are specifically chosen to withstand London’s urban environment and varying weather conditions.

Most London homeowners see a 25-35% reduction in their heating bills after installation. The exact savings depend on your property type, current insulation levels, and energy usage patterns. Properties with solid walls typically see the highest savings.

Generally, external wall insulation and rendering fall under permitted development rights. However, if your property is listed or in a conservation area (common in London), you’ll need to check with your local council. We can assist with this process and ensure compliance with local regulations.

A typical London terraced house usually takes 2-3 weeks from start to finish. This includes preparation, installation, and rendering. Larger properties may take longer. We’ll provide a detailed timeline during your consultation.

While we can install insulation year-round, rendering work requires specific temperature conditions. We carefully plan installations around London’s weather patterns to ensure optimal results.

All external fittings (downpipes, satellite dishes, security lights) are temporarily removed and reinstalled on special extended brackets to accommodate the new wall thickness.

We offer a 25-year warranty on our systems, covering both materials and workmanship. This is backed by our manufacturer’s guarantee and our own insurance-backed warranty.

We offer an extensive range of colours and textures to match London’s diverse architectural styles. Options include smooth modern finishes, traditional textures, and specialist renders for period properties. Costs vary depending on property size, condition, and chosen finish. We provide detailed, no-obligation quotes following a site survey. While the initial investment may seem significant, the energy savings and increased property value typically offer good returns.
