The short answer
Most external rendering costs £40–£70 per square metre fitted in 2026, with basic sand-and-cement at the lower end and through-coloured silicone and lime render at the top. The per-m² rate covers labour, materials and usually scaffold, but it rises when walls need extensive preparation, when access is awkward, or when old render must be removed first. Larger jobs tend to have a lower rate per m², because fixed costs such as scaffold and survey are spread over more wall area. These are typical illustrations, not quotes — see the full rendering cost guide for whole-house figures.
Quotes for rendering are often given as a price per square metre, which makes it easier to compare jobs of different sizes — as long as the quotes cover the same render system, the same preparation and the same scaffold. This guide sets out realistic 2026 per-m² rates for each render type and explains what moves the figure up or down. All figures are typical illustrations rather than quotes, and rendering should be carried out by a trade-accredited rendering specialist.
Cost per square metre at a glance
- Sand-and-cement £30–£50 per m²
- Monocouche £45–£65 per m²
- Silicone / acrylic £50–£70 per m²
- Lime render £55–£80 per m²
- Render over insulation (EWI) £90–£150+ per m²
- Typical semi wall area ~90–120 m²
Per-square-metre rates by render type
The render system you choose is the biggest single factor in the per-m² rate. Sand-and-cement is the cheapest material but is usually painted afterwards, which adds a future cost. Monocouche and through-coloured silicone or acrylic cost more per m² but arrive coloured, so there is no painting and far less maintenance. Lime render is a breathable specialist finish for older walls and sits at the top of the range. Render applied over external wall insulation is a different system entirely and is priced well above plain rendering.
| Render type | Fitted cost per m² | Notes |
|---|---|---|
| Sand-and-cement | £30–£50 | Usually painted; lowest upfront, more upkeep |
| Monocouche | £45–£65 | Through-coloured, single application, no painting |
| Silicone / acrylic | £50–£70 | Flexible, water-repellent, low maintenance |
| Lime render | £55–£80 | Breathable, suits period and solid-wall homes |
| Render over EWI | £90–£150+ | Includes insulation; notifiable under Part L |
What changes the per-m² rate
Two quotes for the same render can differ on a per-m² basis because of what surrounds the rendering itself:
- Preparation and repair — cracked, blown, damp or uneven walls need making good before render goes on, which adds labour per m².
- Removing old render — hacking off and disposing of failed render adds significantly. See remove and re-render costs.
- Height and access — three-storey elevations, scaffold over extensions or restricted access raise the rate.
- Job size — a small area such as a single front wall carries a higher rate than a whole house. See cost to render the front of a house.
- Region — London and the South-East are typically above the national average.
Working out the wall area
To turn a per-m² rate into a job cost, you need the wall area. A renderer measures this on a survey, but as a rough guide a typical 3-bed semi has around 90–120 m² of external wall once doors and windows are deducted. Multiplying the area by the per-m² rate gives a ballpark, but a measured survey is what makes a quote reliable, because it accounts for prep, access and any repairs.

Frequently asked questions
What is the average cost to render per square metre in the UK?
Most external rendering costs £40–£70 per m² fitted in 2026, with sand-and-cement at the lower end and through-coloured silicone and lime render at the top. Render over external wall insulation costs more. These are typical illustrations, not quotes.
Does the per-m² rate include scaffolding?
Sometimes, but not always — some specialists fold scaffold into the per-m² rate and others list it separately. Ask each renderer to confirm whether scaffold, preparation and making good are included before you compare quotes.
Why is a small rendering job more per m²?
Fixed costs such as scaffold, survey and setup are spread over fewer square metres on a small job, so the rate per m² is higher. Rendering a single front elevation typically costs more per m² than rendering a whole house. See cost to render the front of a house.
How do I estimate my wall area for rendering?
As a rough guide a 3-bed semi has around 90–120 m² of external wall once doors and windows are deducted. A renderer measures this accurately on a survey, which is what makes a quote reliable.
