Rendering Cost per m2: 2026 UK Guide to K Rend & Silicone Render
Short answer
As a 2026 UK guide, installed render costs about £35–£55 per m2 for sand and cement, £50–£80 per m2 for a monocouche or K Rend scraped finish, and £55–£95 per m2 for silicone thin-coat render, including labour and materials but excluding scaffolding. Patching or dubbing out hollow areas is typically priced separately at about £30–£60 per m2. Every property differs, so treat these as starting points.
Typical 2026 UK installed guide prices
If you are asking how much rendering costs, start with the system. The figures below are installed ranges for labour and materials; scaffolding is extra.
| Render system | Typical guide price |
|---|---|
| Sand and cement render | About £35–£55 per m2 |
| Monocouche / K Rend scraped finish | About £50–£80 per m2 |
| Silicone thin-coat render | About £55–£95 per m2 |
| Patching / dubbing out hollow areas | About £30–£60 per m2, priced separately |
General UK market guide ranges, not an SJF Plastering price list or quotation. London and the South East typically run 20–30% higher. Scaffolding is not included.
Scaffolding is often the biggest extra
On a two-storey house, scaffolding can be one of the largest single items in a rendering job. Its cost depends on the height and length of the elevations, access from the road or garden, and how long it needs to stay up. Rendering several elevations in one go usually makes better use of the scaffold.
Stripping old render adds cost
New render needs a sound background. If the existing render is cracked, hollow or coming away, it may need hacking off back to the brick or block, which adds labour, waste removal and time. Smaller hollow areas can sometimes be cut out and dubbed out locally rather than stripping a whole wall.
Pebbledash and painted render each need their own preparation before a modern system goes over or replaces them. A visit is the only reliable way to judge how much of the existing finish can stay.
K Rend cost and silicone render cost compared
K Rend is a brand of through-coloured render, available in scraped monocouche and thin-coat silicone systems. A K Rend scraped finish typically sits around £50–£80 per m2; silicone thin-coat systems around £55–£95 per m2, partly because they usually go over a basecoat with mesh.
Sand and cement is cheaper to install but normally needs painting, and repainting every few years. That ongoing cost is easy to overlook when comparing quotes.
Why through-coloured render avoids repainting costs
With through-coloured systems the colour is mixed through the finish coat rather than painted on, so there is no paint layer to flake or fade unevenly. Silicone renders are also water-repellent and tend to shed dirt better. Over the life of the render, avoiding repeated exterior painting and scaffolding can offset part of the higher upfront cost.
A whole-house ballpark
Homeowners often want a figure for a whole house. Honestly, the range is very wide: a small terraced front elevation may be a few thousand pounds, while a detached house with several elevations, scaffolding and old render to remove can run well into five figures. Wall area, the system chosen, scaffolding and the condition of the existing walls all move the total, and every property differs.

Frequently asked questions
What is the rendering cost per m2 in 2026?
As a UK guide, about £35–£55 per m2 for sand and cement, £50–£80 for a monocouche or K Rend scraped finish and £55–£95 for silicone thin-coat render, including labour and materials but not scaffolding.
How much does K Rend cost?
A K Rend scraped monocouche finish is typically about £50–£80 per m2 installed, with silicone thin-coat systems around £55–£95 per m2. Scaffolding and repairs to the background are extra.
Is silicone render worth the extra cost?
It often is if you want low maintenance. The colour runs through the finish and the surface is water-repellent, so it avoids the repainting that sand and cement usually needs.
Does the price include scaffolding?
The guide ranges here do not. Scaffolding is priced separately and is often one of the biggest extras on a two-storey house.
Can new render go over old render or pebbledash?
Sometimes, if the existing surface is sound and properly prepared. Hollow, cracked or loose render needs removing or repairing first.
How much does it cost to render a house?
It varies widely with wall area, the system, scaffolding and the condition of the existing walls — from a few thousand pounds for a small elevation to considerably more for a detached house. A visit gives a firm price.
How long does rendering last?
A well-applied modern render system on a sound, prepared background can last for many years with little maintenance. Preparation and detailing matter as much as the product.

What customers say
Good communication, job arranged quickly
Steve was in touch straight away, gave a very reasonable quote and was good at communicating what was needed and when he would be able to do the work. Steve arrived on time on the day, did a good job and carried out the work in very good time. I would use Steve again for any similar work.
Replacing ceiling due to leak
Steve and his team did an amazing job on our ceiling. We had to get it replaced due to a leak from the flat above and Steve was super communicative, friendly and helpful throughout.
Excellent job!
Had a large hole in the wall which Steve fixed for me, told me the price and gave other options as well all before starting the work. He did an excellent job, got the work done without any fuss!
