Reduce Your Heating Bills by Up to 50% with External Wall Insulation

How it Works

External wall insulation involves fixing a layer of insulation material to the exterior wall of your home, then covering it with a special type of render (plasterwork) or cladding. It is particular useful in old properties, with narrow or absent wall cavities. The finished result not only sigfnificantly reduces heat loss but also renews the appearance of your home.

Take Advantage of the Reduced 0% VAT Deal

Furthermore, in light of the increased energy prices, the government has dropped VAT to 0% on EWI installation until further notice so this is the best time to do it.

Benefits of External Wall Insulation

• Reduces heat loss and energy bills
• Improves the overall look of the home after rendering
• Increases the energy rating of the property
• Reduces carbon footprint
• Future proofs the U rating for your home
• Increases the resale value
• Reduces draughts and adds a sense of comfort
• Improves sound resistance and weatherproofing
• Can help reduce condensation on internal walls
• No disruption inside home during installation
• Does not reduce internal floor area like interior wall insulation does

What is a U Value and Why is it so Important?

The thermal performance of a building is measured in terms of heat loss and is commonly referred to as a U-value (thermal transmittance), or an R-value. U-values (measured in units of W/m²K) determine how effective a material is as an insulator. The lower the U-value, the better it is at preventing heat loss. High U-value materials such as stone, brick, concrete and metal are cold to the touch because they remove the heat from your hand more effectively, so you experience ‘heat loss’. Conversely, low U-value materials such as foam, polystyrene and wool are warmer to the touch because they prevent the heat from your hand, which makes them great insulators.

How Much Does it Cost?

An average three-bedroom semi is likely to cost anything between £5,000-9,000, with a larger detached home in the region of £8,000-15,000.

How Much Can I Save On My Heating Bills?

Installing EWI can reduce your energy bills quite considerably. For instance, if you install insulation with a U-value of 0.31W/m², it can typically reduce your heating energy bills by as much as 50%. As energy prices continue to rise, year on year savings will continue to get bigger too.

Reduce Your Carbon Footprint

The government's plans to reduce the carbon footprint of every UK home means that homeowners will eventually have to make changes to their properties very soon, so it makes sense to do it now whilst there's no VAT to pay and the material prices are still relatively low. As time goes by and the demand grows, you can imagine the prices may increase also.
