The cost of insulating external walls is a common concern for UK homeowners looking to improve energy efficiency and reduce heating bills. At GO2 Services, we specialise in professional external wall insulation services that provide long-term value and comfort. This post explains the process, the benefits, and what to expect from a professional wall insulation survey.
What Is External Wall Insulation?
External wall insulation (EWI) is the process of applying insulation materials to the outside of your home and covering them with a protective render or cladding. This reduces heat loss, enhances appearance, and improves overall energy performance.
Benefits of External Home Insulation
Installing insulation on external walls has many advantages:
- Reduces heating bills
- Improves indoor comfort year-round
- Enhances property appearance
- Increases property market value
- Lowers your carbon footprint

Understanding the Cost of Insulating External Walls
The cost of insulating external walls typically ranges from £90 to £120 per square metre in the UK. Total prices vary depending on:
- Size and layout of your property
- Insulation material and render type
- Accessibility and scaffolding requirements
- Labour and regional pricing
For example, insulating a three-bedroom semi-detached home may cost between £6,000 and £12,000. Though the initial cost of insulating external walls may seem high, the long-term savings on energy bills and increased property value often outweigh the investment.
