The Better Way To Build
Rapid
Our conservatory conversions are pre-manufactured off-site and don’t require any base work. No cement is used so there’s less mess and they can be watertight in only two days.
Lightweight
Our conservatory conversions are designed to be lightweight, so you’ll be able to build on the existing base without compromising on safety. This helps to keep the costs low and installation times short.
Energy Efficient
Converting a conservatory makes it usable all year round. They’re up to five times more energy efficient than the typical UK conservatory and can save as much as £1000 on your heating bills.
Added Value
Converting your old conservatory will help add value to your property. The updated design increases kerb appeal and as the walls are slimmer than brick ones, you’ll also gain extra floor space.

Frequently Asked Questions
When Should I Think About Converting A Conservatory?
It’s not always obvious to spot a conservatory that needs an upgrade, but there are a few warning signs to look out for. If you notice your energy bills creeping up each month or that you’re having to use central heating more often, that’s a good indication. Watch out for repeated problems with condensation and draughts around the windows, as well as any structural damage.
How Much Does A Conservatory Conversion Cost?
Like all home improvement projects, it depends. Multiple factors will affect the budget, from your preferred type of roof, the size of the conservatory and the exact location of your Devon home. If you’d like a personalised estimate, contact us or use our online quoting system.
Will My Conservatory Conversion Require Planning Permission?
It’s very unlikely, but we would always recommend checking with your local authority to be completely certain. Conservatories are considered to be ‘permitted development,’ but there are a few nuances in the conditions that can affect it. We rarely encounter scenarios where planning permission is necessary, but if in doubt, ask.
British Board of Agrément (BBA)
The Ultrapanel technology used in our conservatory conversions has been independently and thoroughly tested, assessed, and approved by the BBA for use in UK housing products. Ultrapanel passed the BBA’s evaluation in thermal and structural performance, condensation, fire, and durability.
Fire Safety
Applus confirmed that the fully assembled walls of our conservatory conversions comply with the Building Regulations’ fire safety standards. Independent fire tests also show that the fully assembled structure of our tiled and solid roofs comply with all the Building Regulations’ fire safety requirements.
NHBC Accepts
The Ultrapanel technology used in our conservatory conversions is used on new houses throughout Warminster and Wiltshire. This has been recognised by NHBC, which provides guarantees on new homes.
Strength
The Steel Construction Institute (SCI) conducted two strength tests on the walls of our conservatory conversions and compared them to traditional brick and block walls. It was found that the walls of our conservatory conversion have the same vertical loading strength as brick walls and are 70% stiffer than brick walls.
Assent
Assent is a Building Control Approved Inspector who works to industry codes of conduct and building control performance standards. The walls and roofs of our conservatory conversions fully comply with Building Regulations and have been pre-approved by Assent.

Happy Customers
Jane Halls
A no-nonsense approach, I didn’t get all the spill talk about discounts and offers at the moment. It’s just a really good quote given at the time. No waste of time phone calls was given the lead time of 12 weeks, which suited us perfectly. Easy to pay the instalments on my phone. The day of installation was very efficient, which was done by Sid.
Moya Paul
Absolutely delighted. The paperwork and organisation were flawless, delivery was on time, the workmanship excellent and the product was of the very highest standard. I thoroughly recommend you to anyone looking for new doors or windows.
Alan
Superb after-sales service. Had porch and front doors installed a few years ago, after contacting Otter Windows, John Capon a man all knowing in this field, promptly arrived and corrected both problems in a true professional manner. I can not rate this company high enough and have recommended them many times.
Matthew Bulliman
Very positive.
Debbie was really helpful in keeping us informed throughout the process. On the day, the fitter was very professional and carried out the work to a very high standard.
Phil Cordon
I was particularly happy with the rear or back door, which I asked to be a barn door. The engineer was honest and gave me proper advice, so I ended up with a split/tilt/open barn door, which far exceeded my expectations.
All work was carried out to a professional finish, and the installer was a very pleasant chap who cleaned up behind himself and left the place clean and tidy.
