How to Use This Rendering Calculator

Step 1: Measure the Wall Height

Measure from the ground (or damp proof course) up to the eaves. A single-storey UK property is typically 2.4m, while a two-storey house is around 5m. If your walls have different heights, calculate each separately.

Step 2: Measure the Wall Width

Measure the horizontal length of the wall face you want to render. If all four walls are different widths, use an average or calculate each wall separately and add the totals together.

Step 3: Choose Your Render Type

Sand/cement is the cheapest option and suits most budgets, but it needs repainting regularly. Monocouche is a popular mid-range choice with built-in colour. Silicone render is the premium option — it's self-cleaning, flexible and lasts the longest, making it ideal for exposed properties.

Step 4: Select the Number of Coats

Two coats is standard for most render types. Sand/cement typically uses a scratch coat plus a finishing coat. Monocouche is designed as a single-coat system but some installers apply two for extra durability. Adding a third coat increases protection but also increases cost proportionally.

Frequently Asked Questions

How much does rendering cost per square metre in the UK?
In 2026, UK rendering costs per square metre vary by type: sand/cement render costs approximately £25–£35/m², monocouche (one-coat through-coloured) render costs £40–£50/m², and silicone render costs £50–£65/m². These prices include materials and labour. Materials-only costs are significantly lower.
What are the different types of wall render?
The three main types of render used in the UK are: sand/cement render (traditional, cheapest, needs painting), monocouche render (factory-mixed, through-coloured, single-coat application), and silicone render (premium, self-cleaning, highly flexible and crack-resistant). Each has different cost, durability and maintenance characteristics.
When is the best time of year to render a house?
The best time to render in the UK is between late spring and early autumn (May–September). Render should not be applied in freezing conditions (below 5°C), heavy rain, or extreme heat. Ideal conditions are mild, overcast days with temperatures between 10–20°C and low wind.
How long does wall render last?
Sand/cement render typically lasts 20–30 years with proper maintenance and repainting every 5–7 years. Monocouche render lasts 25–35 years with minimal maintenance. Silicone render is the most durable, lasting 25–40 years and is largely self-cleaning due to its hydrophobic surface.
Can I render my house myself (DIY)?
Sand/cement rendering can be done as a DIY project if you have plastering experience, though achieving a smooth, even finish requires skill. Monocouche and silicone renders are specialist products that require professional application for warranty coverage and best results. Scaffolding is usually needed for two-storey properties, adding to the cost.
How many coats of render do I need?
Sand/cement render typically requires 2 coats — a scratch coat (base) and a finishing coat — each around 10–15mm thick. Monocouche render is designed as a single-coat system applied at 15–20mm. Silicone render is usually applied in 2 thin coats over a base coat. More coats increase durability but also cost.
