How to Use This Calculator
Select your property type or enter a custom wall area. The calculator automatically adjusts based on typical UK house sizes. Choose your preferred render type and specify wall condition. Regional pricing differences are factored in, with London and the South East typically 15-25% higher than national averages. Tick additional options like scaffolding, old render removal, or insulation to get a comprehensive quote.
Render Types Explained
| Render Type | Cost per m² | Lifespan | Characteristics |
|---|---|---|---|
| Sand & Cement | £30-£50 | 20-30 years | Traditional, requires painting, prone to cracking |
| Acrylic | £55 | 25-30 years | Smooth finish, crack-resistant, quick drying |
| Silicone | £65-£80 | 30+ years | Water-repellent, breathable, low maintenance |
| Monocouche | £80 | 30+ years | Single-coat, through-coloured, no painting needed |
| Lime | £40-£60 | 50+ years | Breathable, heritage properties, flexible |
| Pebbledash | £55-£70 | 20-25 years | Textured finish, durable, traditional appearance |
Cost Factors
- Wall Area: Larger properties require more materials and labour time, directly increasing costs
- Render Material: Premium renders like silicone and monocouche cost more upfront but offer better longevity and lower maintenance
- Wall Condition: Poor condition walls need repairs, repointing, or brick replacement before rendering, adding £1,500-£8,000
- Regional Variation: London costs are typically 20-25% higher than national averages, whilst Northern regions may be 10-15% lower
- Scaffolding: Essential for multi-storey properties, costing £1,000-£4,000 depending on house size and duration
- Preparation: Removing old render costs £1,500-£8,000 for a typical semi-detached house
- Accessibility: Difficult-to-reach areas increase scaffolding complexity and labour time
Typical Project Duration
- 2-bed terraced house: 4-6 days
- 3-bed semi-detached: 1-2 weeks
- 4-5 bed detached: 2-3 weeks
- Additional time needed if removing old render or extensive repairs required
Frequently Asked Questions
Do I need planning permission for rendering?
In most cases, rendering falls under permitted development rights and does not require planning permission. However, if your property is in a conservation area, Area of Outstanding Natural Beauty, or is a listed building, you will need to check with your local planning authority before proceeding.
Are building regulations required?
If you’re rendering 50% or more of any single wall, or 25% or more of your entire external wall area, building regulations apply. This typically requires improving wall insulation to meet current thermal efficiency standards, which may involve cavity wall insulation or external wall insulation boards.
Should I choose DIY or hire a professional?
Whilst DIY can save on labour costs (typically 50-60% of total project cost), rendering requires specialist skills, safety training for working at height, and proper surface preparation. Poor application can lead to cracking, damp penetration, and costly repairs. Professional renderers offer guarantees and ensure compliance with building regulations.
How long does render last?
Traditional sand and cement render lasts 20-30 years with regular maintenance every 5 years. Modern silicone and monocouche renders can last 30+ years with minimal maintenance. Lime render on heritage properties can last 50+ years when properly maintained.
What maintenance does render require?
Sand and cement render needs repainting every 5-10 years to maintain weather protection and appearance. Silicone and monocouche renders are through-coloured and self-cleaning, requiring only occasional washing. Regular inspections for cracks and prompt repairs prevent water ingress and more extensive damage.
Can I render over existing render?
Only if the existing render is in excellent condition, firmly adhered, and compatible with the new render system. In most cases, removal of old render is recommended to ensure proper adhesion and longevity. This adds £1,500-£8,000 to project costs for a typical semi-detached house.
What is external wall insulation?
External Wall Insulation (EWI) involves fixing insulation boards to external walls before applying render. This improves thermal efficiency, reduces heating costs, and may be required by building regulations. EWI systems cost more upfront but offer significant long-term energy savings and can increase property value.
How much does scaffolding cost?
Scaffolding hire for a typical 3-bed semi-detached house costs around £1,000-£1,500. For larger detached properties, expect £2,000-£4,000. Costs depend on house height, duration of hire, and access complexity. Always confirm whether scaffolding is included in your rendering quote.
Choosing the Right Render
Consider your budget, property type, and long-term maintenance when selecting render. Sand and cement render suits tight budgets but requires regular repainting. Silicone and monocouche renders cost more initially but eliminate painting and offer superior weather resistance. For heritage or listed buildings, breathable lime render is often specified to prevent moisture problems in solid walls.
Regional Price Variations
Labour rates vary significantly across the UK. London and South East England typically see costs 20-25% above national averages, whilst Northern England, Scotland, Wales, and Northern Ireland may be 10-15% below. These regional differences reflect local labour costs, material transport, and market competition. Always obtain at least three local quotes for accurate pricing.
When to Re-render
Signs that your property needs re-rendering include visible cracks wider than hairline, render pulling away from walls, damp patches inside your home, areas of render that sound hollow when tapped, and extensive discolouration or staining. Early intervention prevents more serious structural issues and water damage.
