External rendering protects your home from weather and gives it a clean, modern appearance. Prices vary considerably depending on the type of render, the size of the property and its condition. This guide covers all the main options.
External Render Cost by Type
| Render type | Cost per m² | Lifespan |
|---|---|---|
| Sand-and-cement | £25–£45 | 10–20 years |
| Pebble dash | £25–£40 | 15–25 years |
| Monocouche (through-colour) | £45–£65 | 20–25 years |
| Silicone render | £50–£80 | 25+ years |
| Tyrolean | £35–£55 | 15–20 years |
| K-rend (polymer) | £45–£65 | 20–25 years |
Cost by Property Size
A typical semi-detached house has approximately 80–120m² of external wall area. At average silicone render rates, that is £5,000–£9,600 for full rendering. Monocouche on the same house would cost £3,600–£7,800.
Which Render Type is Best?
Silicone render is the premium option: it is flexible (less likely to crack), self-cleaning (hydrophobic surface repels dirt), and comes in a wide range of colours. Monocouche is through-coloured so it does not require painting. Sand-and-cement is the most economical but requires painting every 5–10 years.
Do I Need Planning Permission for Rendering?
In most cases, no. External rendering is considered maintenance under permitted development. However, if your property is in a conservation area or is a listed building, you may need consent. Check with your local planning authority before committing.
