Why Insulate Your Conservatory Roof?

- Improved thermal efficiency โ Having an insulated conservatory roof installed maintains the temperature within your conservatory. This makes your conservatory useable and comfortable all year round.ย
- Lower energy bills โ An insulated conservatory roof will help to retain heat; therefore, youโll spend less money on heating in the winter. You will notice a big improvement and noticeable savings in your energy bills if you have conservatory roof insulation installed.ย
- Increased Property Value โ By having conservatory insulation installed you can add value to your property. Potential buyers are drawn to homes that are energy efficient.ย
- Better sound insulation โ Traditional polycarbonate roofs are not good at blocking out external noises. By having your conservatory roof insulated you can make your conservatory more peaceful and relaxing.ย
- Aesthetic improvements โ An insulated conservatory roof can match the style of your home, giving your conservatory the look and feel of an extension.ย
Average Cost of Conservatory Roof Insulation in 2025
Conservatory rood insulation cost in 2025 depends on the size, style, the type of insulation material and whether youโre replacing the entire roof or not.
Cost Overview by Type
This is a rough guide on what you can expect to pay for conservatory roof insulation:
- Thermal wadding with white woodgrain ceiling โ Expect to pay between ยฃ3,900 to ยฃ7,000.ย
- Replacement insulated solid warm roof – Expect to pay between ยฃ9,500 to ยฃ20,000.
Factors Affecting the Cost of Conservatory Roof Insulationย
1. Size and shape of the conservatory โ
A small lean-to conservatory will cost less to insulate compared to a large Edwardian or Victorian style conservatory because of the differences in materials and labour time.ย
2. Type of existing roof –
Polycarbonate roofs are easier and cheaper to insulate internally than glass ones. However, if your roof is in bad condition a full replacement with a solid insulated conservatory roof might be more cost effective in the long run.ย
3. Type of insulation material –
Different materials provide their own level of thermal efficiency. Material options include the following:
- Multifoil insulation (Most are not fireproof they are a dark space insulator and will within 3 years disintegrate)
- Rigid foam boards (Not appealing due to the look)
- Thermal wadding (Fully tested and compliant system)
4. Location and labour costs โ
The cost of labour will vary depending on the area you live and the size of the job itself.ย
Types of Conservatory Roof Insulationย
There are different types of conservatory roof insulation. This includes:
1. Internal insulation โ
This is where insulation is added to the underside of your existing conservatory roof. Itโs a cost-effective solution that improves your thermal performance without changing the external look. Tis also does not require building control sign off.
2. Solid insulated warm roof replacement โ
The old roof must be removed and replaced with a fully insulated tiled roof. This offers excellent thermal efficiency and will add value to your property. This system requires building control sign off as you are changing the roof materiel.
Do You Need Planning Permission?
Most conservatory roof insulation installations do not need planning permission. However, if you are having a full conservatory roof replacement you might require building regulations approval, to make sure the new roof complies with structural and thermal standards. Or you might need planning permission if the changes alter the exterior appearance or roof height.ย
