Silicone and K Rend cost
Silicone rendering cost sits above traditional sand and cement in most published figures, but the gap depends on what is included and how much preparation your walls need. This guide brings together the silicone and K Rend prices we checked in October 2026, with their sources, and is honest about where the evidence is thin.
Silicone rendering cost per m²
Silicone render is usually priced per square metre, and the published rates vary more than you might expect. Some sources quote an installed price including labour, others quote the cost of the material alone, and one page gives two different ranges in different places. The table below shows each figure as published so you can see what it covers.
| What is priced | Price per m² | Source |
|---|---|---|
| Silicone render, including labour | £65 to £80, average £72.50 | Checkatrade silicone guide, February 2025 |
| Silicone render, often including labour | Around £72.50 | Checkatrade house rendering guide, January 2026 |
| Silicone render | £60 to £100 | MyBuilder rendering guide, August 2026 |
| Silicone render, materials and labour (intro figure) | £40 to £60 | MyBuilder silicone guide, August 2026 |
| Silicone render | £60 to £80 | HomeBuilding.co.uk, October 2024 |
| Silicone render, materials only | £11.80 | Checkatrade silicone guide, February 2025 |
| Silicone render, supply only | £45 to £55, average £50 | MyJobQuote, September 2026 |
MyBuilder's silicone guide gives £40 to £60 per m² in its introduction but £30 to £70 per m² in the body of the same page, so treat its figures with care. The two materials-only figures are also far apart, with Checkatrade at £11.80 per m² and MyJobQuote at £45 to £55, which suggests they are measuring different things. For comparison, Checkatrade's silicone guide gives cement render at £45 per m², acrylic at £55 and polymer or lime at £65.
Silicone render cost by house type
Whole-house prices depend on how many walls are being rendered and how big the sources assume the house to be. Checkatrade's examples count the number of walls, while MyJobQuote gives an area for each house, and its areas are larger than many other sources use. Neither set of figures includes everything, so read the notes in each row.
| Property | Price | Source |
|---|---|---|
| Mid-terrace, two walls, including labour | About £5,000 | Checkatrade, February 2025 |
| Semi-detached, three walls, including labour | About £10,000 | Checkatrade, February 2025 |
| Detached, including labour | About £15,000 | Checkatrade, February 2025 |
| 2-bed bungalow (100 m²), excluding scaffolding | £4,500 to £5,500 | MyJobQuote, September 2026 |
| 3-bed semi (200 m²), excluding scaffolding | £9,000 to £11,000 | MyJobQuote, September 2026 |
| 4-bed detached (300 m²), excluding scaffolding | £13,500 to £16,500 | MyJobQuote, September 2026 |
| Typical 3-bed house (100 to 150 m²) | £6,000 to £12,000 | HomeBuilding.co.uk, October 2024 |

K rendering cost per m²
K Rend is a widely used through-coloured render brand, and many homeowners use the name to mean any coloured thin-coat or silicone render. Despite how often the name comes up, we found very little published pricing for it. Only two of the sources we checked gave a K Rend figure, and they describe different things, so the K rendering cost per m² below should be read as a rough guide only.
Less.co.uk lists K Rend, which it describes as a silicone render, at £45 to £65 per m² with an average of £55, and says its per m² prices include labour and materials but not scaffolding. MyJobQuote gives around £50 per m² for K Rend, but lists it in a section covering supply costs and brands, so it may not include labour. Checkatrade's silicone guide describes K Rend in its FAQs but does not give a price.
| What is priced | Price per m² | Source |
|---|---|---|
| K Rend (silicone render), labour and materials | £45 to £65, average £55 | Less.co.uk, 2026 |
| K Rend (silicone), supply and brand figure | Around £50 | MyJobQuote, October 2026 |
With so little to go on, the most reliable way to price a K Rend job is to get quotes that name the exact product and finish. Ask each plasterer which base coat, mesh and primer they will use, as the finish coat is only part of the system.
What silicone render is and how it differs
Silicone render is a thin-coat finish, usually only a few millimetres thick, applied over a base coat that is reinforced with mesh. The colour runs right through the material, so it does not need painting, and silicone in the mix helps the surface shed water while still letting the wall breathe to a degree. That combination is why it is common on coastal houses and on external wall insulation systems, where a durable, low-maintenance finish is valuable.
Compared with sand and cement, silicone render is more flexible and less prone to cracking, and it tends to stay cleaner for longer, although it is not maintenance free. Compared with monocouche, which is a thicker single-coat render scraped to a texture, silicone gives a finer finish and a wider choice of colours. On solid-walled period houses, lime render is often more suitable because it allows moisture to move freely, so take advice before choosing a modern render for an older building.
What affects silicone render cost
Preparation makes the biggest difference to the final price. Silicone render needs a sound, even background, so loose render, pebbledash or crumbling masonry has to be dealt with first, and that can mean removing the old finish altogether. A full system usually involves a base coat, mesh, primer and the silicone finish, so make sure every quote includes all four rather than the top coat alone.
Scaffolding is often extra, and MyJobQuote's whole-house figures exclude it. Weather matters more than with some renders, because thin coats should not go on in frost, rain or strong sun, and a job can stretch out in a wet spell. Colour choice, grain size and the amount of detailing around windows, corners and the base of the wall all affect the time needed.
- Removing old render or pebbledash before work starts
- Repairs to the masonry underneath
- Base coat, mesh and primer as well as the finish
- Scaffolding, which is often priced separately
- Beads and trims at corners, reveals and the base
- Weather conditions at the time of application
Is silicone render worth the extra
Whether silicone render is worth paying more for depends on the house and how long you plan to stay. Because it is through-coloured, you avoid repainting every few years, which can offset part of the higher upfront cost over time. On a sheltered house where you are happy to repaint, a well-applied sand and cement render may still be the sensible choice, and our house rendering cost guide compares the main options.
If you are thinking about insulating at the same time, silicone render is often used as the finish on external wall insulation, and combining the jobs means paying for scaffolding once. Changing the appearance of a house can need planning permission in a conservation area or on a listed building, so check with your local council first.

How much does it cost to silicone render a semi-detached house?+
Checkatrade puts a semi-detached house with three walls at about £10,000 including labour. MyJobQuote gives £9,000 to £11,000 for a 3-bed semi of 200 m², excluding scaffolding. Your price will depend on wall area and preparation.
Does silicone render need painting?+
No. Silicone render is through-coloured, so the colour runs through the material and it does not need painting when it goes on. It still benefits from occasional cleaning, especially on north-facing or shaded walls.
Is silicone render suitable for an old house?+
It can be used on many houses, but solid-walled period homes often suit lime render better because lime lets moisture escape from the wall. Ask a plasterer to look at the walls before you choose, and check with your council if the house is listed or in a conservation area.
