Rendering Cost Per m² in the UK (2025)
Rendering costs £25–£60 per m² depending on render type. A typical 3-bed semi costs £2,500–£6,000 to fully render externally.
Types of render and costs
Sand and cement render is the traditional option — affordable but needs painting every 5–10 years. Monocouche (through-coloured single coat) is more expensive upfront but never needs painting. Silicone render is flexible, breathable, and self-cleaning — ideal for older or solid-wall properties. Dry dash (pebbledash) is the most economical for weather resistance but has a distinctive textured look.
Does rendering improve insulation?
Standard renders provide minimal insulation improvement. External Wall Insulation (EWI) systems attach insulation boards to the wall before rendering — this can significantly reduce heat loss in older solid-wall properties and may qualify for government energy efficiency grants. EWI costs £80–£150 per m² but can dramatically reduce energy bills.
Cost Breakdown

What Affects the Cost?
- ✓Total wall area in m²
- ✓Render type chosen
- ✓Condition of existing render — hacking off old render adds cost
- ✓Number of windows, doors, and details to work around
- ✓Whether scaffolding is required (usually yes for full external renders)
- ✓Location — London and South East rates are higher

How long does render last?
Sand and cement render lasts 20–30 years if well maintained and painted regularly. Monocouche and silicone renders have similar lifespans and require virtually no maintenance.
Do I need planning permission for rendering?
Rendering a house does not usually require planning permission. However, in conservation areas or for listed buildings, changes to external appearance may require consent. Check with your local planning authority if unsure.
Can rendering help fix damp?
It can — but only if the damp is caused by water penetration through the wall. Internal rising damp requires damp proofing treatment first. If render is applied over a damp problem without treating the cause, the problem will return.
