Understanding these factors helps you compare quotes and choose an option that balances aesthetics, performance, and budget.
How Design Choices Affect EWI Cost
The design and finish of your EWI system significantly influence pricing. Consider the following:
| Design/Finish Option | Typical Cost per m² | Impact on Overall Price | Benefits |
| Smooth Silicone Render | £35–£50 | Moderate | Low maintenance, modern look |
| Textured Mineral Render | £40–£55 | Higher due to application | Breathable, natural appearance |
| Acrylic Render | £30–£45 | Moderate | Flexible, vibrant colours |
| Brick Slips | £50–£70 | Premium | Heritage style, premium visual appeal |
Choosing a more intricate or premium design increases the cost per m² but can significantly enhance the property’s aesthetic and long-term durability.
How to Calculate Your Total EWI Cost
To estimate total costs based on per m² pricing:
- Measure the total wall area to be insulated.
- Multiply the area by the chosen insulation and render cost per m².
- Add any additional preparation, scaffolding, or repair costs.
For example, a 100 m² property using mineral render at £45 per m² would have a base material and labour cost of £4,500, excluding additional work. Consulting an installer ensures a complete and accurate quote.
Is Paying More for Design Worth It?
Investing in higher-quality or customised render finishes can provide long-term benefits:
Even though the upfront cost may be higher, the investment pays off through reduced maintenance and improved energy savings.
