How Much Does Conservatory Insulation Cost?
In the majority of conservatories, the internal conservatory roof insulation panels are constructed of several layers of high-quality polished reflective film as well as thermal webbing.
This insulation tucks between the ceiling beams neatly. It is then coated with either a uPVC finish or plaster finish, which conceals the insulation and improves the aesthetic appearance of the roof.
The average conservatory roof insulation cost is between £1,200 and £4,000. The exact price you're quoted by tradespeople will depend on the size and style of your conservatory roof.
The price quoted will include all of the costs, including labour costs, material costs, and decorating costs if needed.
There are several different types of insulation for a conservatory. Each of these different types comes with various price points. While insulating a conservatory isn't cheap, it is worth it in the long run as it can reduce your energy costs and prevent heat from escaping.
My conservatory is in good condition but looks a bit dated. Are there any changes I can make to modernise it?
"One change you could make is to the colour of the conservatory. I know some really good guys that spray uPVC and offer warranty for colour fade etc.
Another popular home improvement we do is conservatory roof replacement. This can change the entire look and feel of the conservatory and actually has huge energy efficient benefits."

What Impacts Conservatory Insulation Costs?
Several things may affect the overall cost of getting insulation installed on your conservatory. Below is a list of things you may need to keep in mind when budgeting for your conservatory insulation project.
Type of Conservatory Insulation
The type of insulation that you choose can result in varying costs. As we have already mentioned, there are several different types of insulation for your conservatory. Each of these types of insulation comes at a different cost, as detailed in the table above.
The materials of these insulations have varying costs. Plus, some are easier to install than others. This results in the timescales for the installation varying, which has an impact on the labour costs.
Is it possible to put a tiled or solid roof on my uPVC conservatory?
"You can put a lightweight insulated roof on it but not concrete tiles as they are too heavy."
Size of Your Conservatory
The size of your conservatory will also affect the job's overall cost. The larger your conservatory is, the longer it will take the contractors to fit all of the insulation. This will result in higher labour costs. Larger conservatories will also require more materials for the job, so this will affect the cost as well.
Location in the UK
The location of your property will also affect the price you will pay to have insulation installed in your conservatory. Those based in and around the area of London can expect to pay more for the work than people who are based in the North or different areas of the UK. This type of work is in high demand in this area, so the labour costs are likely to be considerably more.
Additional Conservatory Insulation Costs
You may need to budget for several additional things when insulating your conservatory. Below is a list of things you may need to consider with this type of work.
New Conservatory Cost
If you are looking into the cost of conservatory insulation, then you may also be interested in the cost of an entirely new conservatory. There are several different types of conservatories, and the prices will vary depending on the type and size you require.
The average cost of a conservatory is between £7,000 and £12,000. This is quite a large job and may take several weeks to complete, depending on how large the conservatory is going to be.
Painting and Decorating Price
When your conservatory insulation job is complete, it’s very likely that you’ll want to decorate the room. While you can decorate it yourself, many people prefer to hire a professional to take care of this type of work.
The average cost to painting a room is between £180 and £500. The price you're quoted will depend on the type of finish you're looking for, your location in the UK, and the size of the conservatory you're decorating.
New Conservatory Flooring Cost
As well as painting and decorating your conservatory, you may also be interested in getting some new flooring installed once the roof has been insulated. Some people may choose to fit new flooring themselves, but most people prefer a professional to do this type of work.
Luxury Vinyl Tiles (LVT) are one of the most popular types of conservatory flooring in 2025. The average LVT flooring cost is between £25 and £40 per m².
There are lots of other options though, but you're looking at somewhere between £400 and £1,000 for an average-sized conservatory. The exact prices you're quoted by flooring installers will depend on the size of the conservatory, the type of flooring that you choose to go with, and your location in the UK.
Underfloor Heating Cost
If you are planning on insulating the conservatory, you may also be interested in additional ways in which you can keep the room warm. Underfloor heating is one of the best ways to add some heat to a conservatory room.
The cost of underfloor heating will depend mostly on the size of the conservatory. However, you can expect it to typically cost between £600 and £1,500 for an average-sized conservatory.
What’s Involved in Insulating a Conservatory?
If you are planning on getting this type of work done on your home, then you may be interested in learning the steps involved so that you can be prepared when the time comes. Below is an overview of the steps that are taken when insulating a conservatory.
- During the first step, the contractors will inspect your current conservatory roof and advise the best type of insulation for your particular conservatory.
- The contractors will then gather the materials needed to install your insulation before the agreed date of the work.
- On the insulation day, the contractors will install fire-retardant insulation that covers the roof structure. All electrical wiring that is required to power the overhead lighting is also fixed into position during this stage.
- An external water-tight roof layer will then be added to the aluminium subframe, and the contractors will put your external roof in place.
- Your contractors will then complete your internal roof to the highest standard possible and create a beautiful ceiling which can be decorated or painted as you want.
- Finally, the contractors will check over everything to ensure it is of the highest standard, and they will check with you to ensure you're happy with the final result.
Can I Insulate a Conservatory Myself?
If you have a lot of knowledge in the area of installing insulation in a conservatory, then you may be able to complete this type of work yourself. However, it can be quite a labour-intensive job, so you will most likely need at least one additional person on hand to help you.
In most cases, people prefer to leave this type of work to the professionals. By doing so, you'll ensure that the work is completed correctly and safely. This will also ensure no damage is done to your existing conservatory roof or structure.
How do you make sure that a conservatory doesn't get too hot or cold?
"You can now fit an insulated tiled roof to a conservatory, with the option to include Velux or glass panels if additional light is required. We manufacture and install a system specifically designed to reduce heat in the summer and retain warmth in the winter."
Building Regulations and Planning Permission for Conservatory Insulation
When carrying out any type of work on your home, it’s important to know beforehand whether you’ll need to worry about planning permission or building regulations.
When it comes to insulating your conservatory, you won’t usually need to worry about planning permission or building regulations.
However, if you are carrying out any significant changes to the structure of the conservatory or if you are making changes to the height, pitch, or materials of the roof, then you may need to obtain planning permission.
If you are unsure about whether or not you’ll need to worry about planning permission or building regulations, it’s always best to check beforehand with your local authority.
Types of Conservatory Roof Insulation
There are several different types of conservatory insulations that you may wish to use. This section will go over the different types of conservatory insulations and the pros and cons of each type.
Plastered Conservatory Roof Insulation

The plastered finish on the ceiling will provide an aesthetically pleasing appearance that makes your conservatory look like a completely integrated part of the house. With this type of insulation, there is no need to remove the existing roof elements, so this results in less clutter and mess.
These insulation conservatory roof insulation panels are very thermally efficient and allow very little heat loss. With this in mind, these are great for keeping the heat in. Despite the addition of the insulation boards and plaster, your conservatory roof will remain preserved, and you won't lose a lot of ceiling height.
This means that the structural changes to the room will be minimal, and this is beneficial for the space in the room. This type of new insulation can also provide soundproofing properties.
Pros

✔ Long-lasting
✔ Keeps the warmth in during the winter
Cons
✖ Can be expensive
uPVC Conservatory Roof Insulation
The new roofing material will be installed on the exterior roof with this type of insulation. Depending on the type of insulation system that is installed, the glass panelling of the roof may or may not be removed.

Pros
✔ Good for temperature control
✔ Easy to maintain
✔ Aesthetically pleasing
✔ Easy to install
Cons
✖ Not as durable as some other types of insulation

✔ Durable
✔ Quite cheap to install
✔ Easy to install
Cons
✖ Less aesthetically pleasing than other methods
✖ Not great for keeping the heat in

FAQs
What is the best insulation for a conservatory roof?
If you are looking for a heat reflector, aluminium roof boards and thermal wadding are the most popular option as they are seen as the most effective for this. This is also a great, cost-effective solution to keeping your conservatory cool in the summer months. Thermal wadding can absorb heat through air pockets, which trap the heat and provide an effective, simple solution to your insulation problems.
Is it worth installing conservatory insulation?
Installing insulation in your conservatory will endure some higher costs than if you were to leave your conservatory with a traditional roof. However, this type of insulation could add some value to your home and could result in saving some money on your energy bills over the years.
Are there any grants to help with conservatory roof insulation costs?
No, there is currently no funding available to UK residents to help with conservatory roof insulation costs.
The latest iteration of the Energy Company Obligation (ECO) only helps eligible tenants and homeowners in the UK access funding to help with essential upgrades (e.g., loft insulation, boiler replacement) that improve energy efficiency and lower heating costs.
However, there may be exceptions to this that are considered on a case-by-case basis when applying for funding. For instance, if the conservatory is an integrated part of the home (liveable) and has a demonstrably negative impact on the home's energy efficiency.

What if my conservatory roof is made from glass?
If you have a glass conservatory roof, ordinary roof insulation would not be an appropriate option. A good alternative, in this case, would be a solar reflective film. This type of insulation reflects some of the solar energy from the sun so that your conservatory remains at a cooler and more comfortable temperature.
Can I install a proper roof on my conservatory?
It is possible to install a proper, solid roof to your conservatory. This type of roof can improve the energy efficiency of the room, which can help it to remain warm in the winter months and cool in the summer months.
This means that you can enjoy your conservatory space all throughout the year without having to worry about what the weather is like during that time of the year.
This means that you can enjoy your conservatory space all throughout the year without having to worry about what the weather is like during that time of the year.
What causes a conservatory to become cold?
Most conservatories are made up of mostly glass panels. Glass doesn't retain heat or provide much protection from the weather outside. With this in mind, heat can escape quickly from the room during the winter, while in the summer, the room can become very overheated. The roof is usually the biggest cause of heat loss in a conservatory.
Around 80% of conservatory heat loss is through the roof. This is why it's always best to install insulation on the roof of your conservatory. If you want to be able to use your conservatory all throughout the year, regardless of the outdoor temperature, roof insulation is the best way to go.
