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.

Our installation work is covered by a 10-year workmanship warranty: if a defect arises from our installation during that period, we’ll return and put it right at no additional cost. The products we use are also covered by their manufacturer’s own warranty. Full terms are provided in writing with your quote.

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.

The complete replacement of the previous painted render by a coloured silicon render finish has both improved the overall protection and visual impact of our house. The works were conducted in a very efficient & professional manner.: the work was Project managed by Derek and executed in a clean, friendly & professional manner by Maha & Aleen.

Very smooth process from start to finish. I initially sent over some photos of the front and side walls of my house and received a rough quote. The team then came out to carry out a proper survey and finalise everything. The quote arrived within a couple of days and was clear, straightforward, and without any hidden costs. The work was completed on time and to a very high standard. Really pleased with the result and the whole experience. Can't ask for much more than that. Highly recommended.

I absolutely love the work the lovely Carlos has done with our exterior wall! He was quick, professional, polite and a great chap! Derek's emails were super polite and responsive too I'd highly highly recommend Advanced Wall Protection to anyone it's fantastic quality for the cost. The photo doesn't do it justice the rendering is a beautiful happy magnolia colour which is a lovely welcome home colour! :)

Wow! AWP have just finished our home to an extremely high standard. Their attention to detail and thoughtfulness about our home is a real credit to the business. From my first interaction with the company talking to the sale team and then Derek coming round to survey the property. The teams of guys that came and worked at our home showed care, they were hard-working and cleaned up every day, so we never felt we were in the middle of a building site.
