How much does rendering cost?

There are several reasons why people choose to render their homes. It provides a decorative finish that can really brighten up tired houses, especially those with damaged brickwork or existing discoloured render. It is also the final stage of external wall insulation.

When it comes to knowing which render to choose, all the terminology can be a bit baffling. What’s the difference between different types, and how much do they cost? We have looked at costs across the country for different types of rendering system. Below, we talk you through the options, from the highest cost to the lowest, with an introduction of how render types differ.

Rather than just giving example costs for different types of material, we thought it would make sense to give rough costs for different part of the country, as installation costs tend to be more expensive the further south the property.

Before we start, we should say that we’re basing our estimates on these average sizes:

Small mid-terrace house = 40-50m2

Large mid-terrace house = 70-170m2

3 bed semi-detached = 110-160m2

3 bed detached = 110-160m2

4-5 bed detached = 180m2+

To get an idea of costs, multiply the price per square meter of the property type you are looking to render by the cost of installation in your area of your chosen type of render. These are listed below:

External wall insulation

South £100-150 per m2
Midlands £85-130 per m2
North £80-120 per m2

External wall insulation means fixing solid insulation boards to the outside of a property, before finishing with primer and a thin-coat acrylic or silicone render. The final price depends on the exact system you choose, but it will be roughly twice as much as coloured render, as there is much more work and more materials required. However, render and EWI should not really be compared like-for-like, as they offer completely different solutions. Render can lift the appearance of your property, and protect its walls, but it does not improve its thermal performance. While render is cheaper, external wall insulation will save you money on your heating bills in the long run.

Silicone or acrylic thin-coat render

South £60-75 per m2
Midlands £50-60 per m2
North £45-60 per m2

(Silicone render is more expensive than acrylic render, by £1-2 per m2)

Silicone and acrylic renders are the newest and best-performing type of render. They are more expensive because they are flexible, meaning they will move with the building and not crack. Also, silicone stays cleaner for longer so it will keep your render looking new. If you’re going down the render-only route, it’s probably worth spending a little extra money in the first place for a finish that will stand the test of time.

Monocouche/colour render

South £50-70 per m2
Midlands £35-55 per m2
North £35-50 per m2

Modern through-coloured render provides a decorative, weather-proof finish for external walls. Unlike render covered with paint, it does not show scratches and therefore stays looking newer for longer.

Some systems have mesh sunk into the render around doors and windows to give them extra strength. Fully-meshed systems give extra strength and impact resistance, but will cost around £2-5 extra per m2. What goes into the Monocouche render system? Our friends over at EWI Store have written a blog all about the different components and how much they cost.

Sand and cement render


South £35-45 per m2
Midlands £25-35 per m2
North £20-30 per m2

This is a traditional type of render that has been around for years. Although on paper it’s cheaper than newer render types, there’s a false economy at play; because the sand and cement render will need to be painted after installation, it will probably end up costing the same overall as coloured render systems. Bearing this in mind, it may be wise to opt for a newer render type, which gives a higher performing finish.

Additional costs to bear in mind

We have not included the following extra costs in our calculations, because they vary so much from job to job:

    • Scaffolding
    • Priming
    • Removing and disposing of old render (if applicable)
    • Beading around windows and doors – the more windows and doors, the more the job will cost, so a plain wall could cost less than one with lots of windows, even if the square meterage is bigger.
