Helping you spread the cost of your project

Every conservatory is different. Some homeowners want to improve comfort without changing the outside of the roof. Others want a tiled finish or a brighter orangery-style conversion. CI Group offers three specialist systems so you can choose the level of transformation that suits your conservatory.

Product 1: C.H.R.I.S®

C.H.R.I.S® Internal Roof Insulation

est for:
Improving comfort without replacing the external conservatory roof.

What it does:

A lower-disruption upgrade, no major structural changes in most cases, and a conservatory that feels more usable throughout the year.

Too hot, too cold, too noisy or simply underused?

Many conservatories are difficult to enjoy all year round. They can overheat in direct sun, feel cold during winter, become noisy in rain and feel disconnected from the rest of the home. CI Group’s conservatory roof systems are designed to help solve these problems by improving comfort, usability and the overall feel of the room.

Do you own a commercial property with an unusable conservatory? 

Conservatories are not only used in homes. Nursing homes, pubs, hotels, golf clubs, restaurants and leisure venues often rely on conservatory spaces for dining areas, lounges, guest seating and additional usable floor space. When those rooms become too hot, too cold or uncomfortable, they can limit how often the space can be used.

CI Group works with commercial property owners and managers to improve conservatory comfort, usability and appearance through specialist roof insulation and roof conversion systems.

Just had our conservatory roof tiled. The installation team were really good, completed the job in 2 days. Everything was cleaned down by them when all finished. Roof looks amazing. They had already insulated our conservatory roof a few years ago, so we’re really happy with everything done now Thanks CI

The salesman was very clear polite and went over everything clearly. Wanted a tiled roof but after surveyor came out was very nice. Explained to be why a could not have a tiled roof.this was very helpful as other companies just said yes I can have one this is the only company who sent a surveyor out. Hope it is all good when done.

I just thought I would get in touch to say how happy I was with both Fred and Jordan workmanship they were consummate professionals. They kept me informed of each stage and the pull down and set up was so quick and very professional.

I would be happy to do a review on trustpilot if you’re on trustpilot. If you are on trust pilot could you send me a link and I’ll get it completed otherwise happy to spread the word by word-of-mouth I would definitely recommend you guys every single time😀

Once again, thank you very much for your service.

Kind regards

Dear Chris, sales team,

I’m taking a moment to write to say that your insulation system has been much on our mind recently, in the current heatwave.  We continue to be very pleased with it; we know that from previous years the current exceptional outside temperatures would have made the kitchen room unusable, whereas now the room temperature is much as the rest of the house (still hot, but workable).  Changes in temperature between rooms in the colder months were less noticeable too.  It has been a successful solution, and we are pleased to have persevered in getting what is right for us.  If you’d like a further testimonial, or would like a reference from us for other prospective clients, feel free to ask.

Kind regards

“I’m very pleased with the installation in my conservatory. I found that it’s warmer in winter and cooler in summer which means I could use it all year round. Also very pleased with the workmanship and how quickly it was fitted.”
Harold Howarth, 1 year ago
“I’d like to give a huge thank you to all at CI Group for the fantastic customer service and installation of our insulation fitted this month. Keith who came out to do the survey was so friendly and knowledgable. Rob & Curtis who came out to fit the insulation were amazing! Nice guys, couldn’t do enough for us. Fitted within 3 hours, very tidy and even fitted a new light for us that we had chosen. Our conservatory is so much warmer already and we are looking forward to have it nice and cool in the summer.”
Jack Whittaker, 1 year ago
“Over the moon with what feels like a brand new conservatory! Workmanship was great - the lads who fitted it were also really friendly and professional. The finish of the boards are really high quality and it has transformed my house. Cool in summer, warmer in winter. Happy days. Highly recommend!”
Dave Fysh, 2 years ago
“Since we first contacted Conservatory Insulations and made an appointment for Chris to come and talk to us about their product, we have been very impressed with the professional way we were given all the information we needed to make a decision about having our conservatory insulated and how well the actual work was executed. At this point, we have only had the interior insulation done by them but may, in the future, have the glass removed and replaced by tiles. We have noticed a big difference in how much warmer the conservatory is now that we are heading into autumn and winter.”
Lyn, 2 years ago
“Excellent from start to finish. The estimate was given using my measurements and photographs and arrived by email - no pushy sales technique. Once I decided to proceed we agreed on a date - early January. The installers arrived by 8am and did a wonderful job. They were hard working, experienced, polite and friendly. The finished product is excellent and we’ve remarked all summer how much more comfortable it is to sit in the conservatory out of the glare of the sun. I can highly recommend them.”
Bob McGovern, 2 years ago
“I'm really impressed with my conservatory roof insulation. Just gone 12 months since installation, and the difference in temperature is amazing, cooler in the summer, and a lot warmer during winter. Now, my conservatory can be used any month of the year. The service received from the sales demonstration through to installation was excellent. The fitters were polite, tidy, and very efficient. Also, the look and quality of this product is fantastic.
Pictures of before and after included”
Carole Nash, 2 years ago
“Very impressed with the efficiency and speed of installation of the Conservatory insulation. Like the look and can now use the conservatory even on a warm day. Very knowledgeable team of installers and very happy with the quality of the work carried out.”
Steve Day, 2 years ago

Great service from beginning to end from initial consultation where product was fully explained and installation explained. turned my conservatory from a 'walk through' room into one I use all year round. Cannot recommend them highly enough.

Susan Sherman, 2 years ago
“A wonderful addition to my conservatory. I can now use it any time if the year. A beautiful product and looks good. The workmen were very clean and tidy and it took lest than a day to fully complete.”
Margaret Davies, 2 years ago
“My conservatory was build in October 2004 but got very little use as in the winter it was far too cold and in the summer far too hot. In 2018 I changed to roof for a glass one with the darkest tint; it made virtually no difference. The furniture, photos and pictures all faded as the sun was so bright, and the candles melted!

In April 2023 I got the CHRIS insulation system fitted by conservatory insulations. It’s made the world of difference. The room is now usable all year round. In the interest of full disclose I admit it’s not as quite as warm as the rest of the house in the winter, or as cool in the summer, but it wouldn’t be, it’s not made of brick with cavity wall insulation, I didn’t expect miracles! But it is a huge improvement and I am really pleased. I’d recommend it to anyone with the same issues.”
Sue Can, 2 years ago
“Conservatory insulation fitted to the inside of roof has kept the room cooler in summer and warmer in winter. Also reduced noise and dispensed with flies. A great job from Conservatory Insulations. It has the added benefit of looking much better than glass.”
Stuart Cairncross, 2 years ago
“Had roof installed last April so its been through a few seasons. One of the best things I’ve ever done. I now have a usable room for 12 months of the year rather than about 4. Definately warmer in winter and cooler in summer. Also noise reduction is worth mentioning. Previously it could be so noisy - not any more. I would highly recommend this company. They are very professional to deal with from start to finish. The work was done as scheduled and was completed in half a day with no mess.”
KT M, 2 years ago
“We love our conservatory ceiling.
From our initial demonstration of the product to the guys coming to fit.
Everyone we met was really nice. When the guys were fitting the ceiling, they helped by fitting our new lights and even gave us the bulbs !!
Sitting in the conservatory over Christmas time with our decorations up was really cosy.
A family member went to another company and is jealous of our finish and how warm it is in the winter.”
Bev Griffiths, 2 years ago
“A fantastic transformation of our previously too hot/too cold conservatory.
The on-site team were nothing short of amazing in how quick they worked, all completed within one day
This has totally transformed how we use this room and 1-year on, it is now the most used room in the house
We couldn’t be more pleased with how it’s turned out
Communication from Conservatory Insulations was faultless throughout the process, from initial appointment thru to completion and after-sales service”
Nigel Staples, 2 years ago
“I can highly recommend getting your conservatory insulated. It has completely changed when/how we use the conservatory now. Warm in winter, not unbearable in the summer !
We had our installation a year ago and wished we’d done it sooner.

Christina Moore, 2 years ago
“Absolutely superb. We are 1 year into our Conservatory Insulations installed ceiling.

Quote was competitive, and after going round to visit a local house who had had it done, we went ahead and the insulation installed on our PVC roofed large conservatory. It is our dining room, so an important space, with usual issues of too hot in summer and too cold (really cold!) in winter.

The fitters arrived on the scheduled day, and completed the work quickly and did a great job of everything.

We also installed perfect fit thermal blinds, which also help.

Since then we have been through a summer with good hot spells, and a winter with plenty of cold, wet and snowy weather.

It is a cliche - but usably cool in the summer and warm in the winter are absolutely correct. It has completely transformed the room, way beyond expectations.

Interestingly, as the conservatory is an extension to the kitchen, we were worried about the new ceiling blocking too much light and making the interior of the kitchen darker. The opposite is true - it reflects more light in general into kitchen and around the conservatory so the whole thing is brighter, without the feeling of being underneath a solar magnifier.

Highly recommended.”
Kevin Simpson, 2 years ago
“Excellent job from start to finish
The salesman came round and after a bit of haggling made us a great offer which we accepted. They kept us informed until the day the fitting team turned up.
The fitting team were very professional and made an excellent job no mess either.
We can’t recommend them enough excellent service”
Gary Whiteside, 2 years ago
“I am so pleased with my new roof on my conservatory. I’m able to use it all year round now instead of shutting it up for winter The lads were very professional and polite. There was no mess left after installation.”
