Both cavity wall insulation and external wall insulation are cost-effective ways of keeping your home warmer for longer.
Cavity wall insulation is placed between the inner and outer layers of a building’s external walls to help reduce heat loss.
External wall insulation is applied to the outer walls of a building to improve its energy efficiency and appearance.
Read on to explore more of the differences in the application, benefits and cost of these two popular types of insulation.
How do cavity wall insulation and external wall insulation work differently?
Cavity wall insulation
Cavity wall insulation fills the space between the inner and outer layers of a wall to prevent heat from escaping. This makes it faster to heat your home and easier to maintain a comfortable temperature year-round. Reducing the amount of heat that escapes through your external walls helps to regulate your home’s temperature more efficiently, without adjusting the heating.
External wall insulation
External wall insulation provides your home with a barrier against the elements, particularly in the hotter summer and colder winter months. This helps to keep your home warm in the winter and cooler in the summer, resulting in less reliance on heating and air conditioning to maintain a comfortable temperature.
What are the benefits of cavity wall insulation?
Lower energy bills
Enjoying a consistently warmer home during the colder months reduces your reliance on using heating to keep the winter chill at bay. As a result, your heating bills could be reduced by up to 30%.
Reduced condensation
Condensation is usually a result of moisture forming on the surface of cold internal walls. By raising the temperature of your internal walls, cavity wall insulation reduces the amount of dampness and mould that forms.
Lower noise pollution
Homes in busy urban areas frequently experience noise pollution from street traffic and neighbouring buildings. Cavity wall insulation acts as a sound barrier between the inside and outside walls of a building, helping to reduce external noise interference.
What is the average cavity wall insulation cost?
Cavity wall insulation is a relatively low-cost solution for enhancing your home’s energy efficiency. Homeowners can typically expect to pay from £850 – 1,300 for a mid-terrace to £1,600 – 3,500+ for a detached property.

What are the benefits of external wall insulation?
Energy efficiency
External wall insulation can lower your energy bills and carbon emissions by cladding your external walls with an insulated layer. This helps to keep the warmth in and reduces the reliance on using excessive heating in winter.
Improved comfort
If there are cold spots or draughts in your home, external wall insulation can eliminate them. By applying cladding to your walls, external wall insulation forms a barrier against the elements and helps to prevent heat from escaping.
Increased property value
By enhancing your home’s appearance and energy efficiency, external wall insulation can increase its value and make it a more attractive prospect to future buyers.
What is the average external wall insulation cost?
The cost of external wall insulation depends on the size and type of property. Homeowners can typically expect to pay from £10,000 – £15,000 for a mid-terrace to £15,000 – £30,000+ for a detached property.
