The short answer
Rendering a typical 3-bed semi usually costs £3,000–£8,000 in 2026, with most fitted work falling around £40–£70 per square metre. The render type makes the biggest difference: basic sand-and-cement is the cheapest per m², while through-coloured silicone and monocouche cost more but need less maintenance. Height and access, the condition of the existing walls, and whether old render must be removed first all move the price. These are typical illustrations, not quotes — see the cost per square metre guide for a closer breakdown.
Rendering is one of the larger external jobs a UK household takes on, and the range of prices quoted — from a few thousand pounds for a single elevation to well into five figures for a large re-render — can make it hard to know what is reasonable. This guide sets out realistic 2026 fitted ranges for the main render types, explains what drives the differences, and flags the scenarios that push costs up so there are no surprises in a quote. All figures are typical illustrations rather than quotes, and rendering should be carried out by a trade-accredited rendering specialist — for example, a manufacturer-approved installer of a through-coloured render system.
Rendering costs at a glance
- Sand-and-cement render (fitted) £30–£50 per m²
- Monocouche render (fitted) £45–£65 per m²
- Silicone / acrylic render (fitted) £50–£70 per m²
- Lime render (fitted) £55–£80 per m²
- Whole 3-bed semi £3,000–£8,000
- Render over external wall insulation (EWI) £90–£150+ per m²
Sand-and-cement and monocouche render costs
Traditional sand-and-cement render is the most affordable option, typically £30–£50 per square metre fitted, but it is usually painted afterwards and can be more prone to cracking and staining over time, so it needs more upkeep. Monocouche is a through-coloured, factory-batched render applied in a single thickness; at roughly £45–£65 per m² fitted it costs more than sand-and-cement but does not need painting, because the colour runs through the render. The per-m² figure usually eases on larger jobs, because the renderer’s setup, scaffold and survey costs are spread across more wall area. Location matters too: London and the South-East are typically higher than the national average. See our types of render explained guide for how each finish behaves.
| Render type | Fitted cost per m² | Whole 3-bed semi (approx.) |
|---|---|---|
| Sand-and-cement | £30–£50 | £3,000–£5,500 |
| Monocouche | £45–£65 | £4,500–£7,000 |
| Silicone / acrylic | £50–£70 | £5,000–£8,000 |
| Lime render | £55–£80 | £5,500–£9,000+ |
Silicone, acrylic and lime render costs
Through-coloured silicone and acrylic renders are the popular modern choice; at around £50–£70 per m² fitted they cost more than sand-and-cement, but they are flexible, water-repellent and self-cleaning, so they resist cracking and staining and need little maintenance. Lime render suits older, solid-wall and period properties because it is breathable and allows damp to escape; it is a specialist finish and tends to be the most expensive at £55–£80 per m². The right choice depends on your walls as much as your budget — for a closer comparison see silicone vs acrylic vs monocouche render.
What pushes costs up
Several factors can push a rendering job above the typical ranges:
- Removing old render first — hacking off, disposing of and repairing the wall before re-rendering adds labour and waste cost. See our remove and re-render cost guide.
- Height and access — three-storey walls, restricted access and scaffolding over conservatories or extensions add to the price.
- Wall preparation and repair — cracks, blown areas, damp or uneven substrate all need making good before render goes on.
- External wall insulation (EWI) — rendering over insulation boards is a different, more expensive job and brings Building Regulations into play.
- Conservation areas and listed buildings — specified finishes such as lime render, and possible planning permission, can both add cost.
Render over insulation and energy efficiency
If you are rendering as part of an external wall insulation (EWI) system, the cost is significantly higher — often £90–£150 or more per m² — because insulation boards are fixed to the wall before the render coats go on. This kind of work improves the thermal performance of solid walls and is notifiable under Building Regulations Approved Document L, so it should be carried out by an installer who can certify the system. Plain re-rendering of bare or sound walls is not usually notifiable, but adding insulation changes that. See is rendering worth it for how the warmth and maintenance benefits weigh against the cost.
Quotes, accreditation and warranties
Whoever carries out the work, ask for an itemised written quote covering preparation, scaffold, the number and type of coats, the render system and the warranty. Many through-coloured render systems come with a manufacturer-backed warranty, but that warranty usually depends on the work being done by an approved installer using the full system. This is general information; costs vary with your specific home and the quotes you receive, and rendering should be carried out by a trade-accredited rendering specialist.
Frequently asked questions
How much does it cost to render a 3-bedroom house?
A typical three-bedroom semi generally costs £3,000–£8,000 to render in 2026, depending on the render type, the height and access, and how much preparation the walls need. Through-coloured silicone or monocouche, three-storey walls or removing old render first can push this higher. These are typical illustrations, not quotes — get at least three itemised estimates for your property.
How much does rendering cost per square metre?
Fitted rendering typically costs £30–£50 per m² for sand-and-cement, £45–£65 for monocouche and £50–£70 for silicone or acrylic in 2026. Lime render and render over insulation cost more. See our cost per square metre guide for the detail.
Is silicone render worth the extra cost?
For many homes, yes — through-coloured silicone render is flexible, water-repellent and largely self-cleaning, so it resists cracking and staining and needs little maintenance, unlike painted sand-and-cement. Whether the extra outlay is justified depends on your walls and how long you plan to stay. See silicone vs acrylic vs monocouche.
Does rendering add value to a house?
Fresh, well-applied render can improve kerb appeal and support a home’s value, and rendering over insulation can help the EPC rating. The exact effect varies by property and area, and it is rarely a direct pound-for-pound return on the cost. See does rendering add value.
