Energy Efficient & Secure Conservatories
Our conservatory installations deliver exceptional thermal efficiency and high security, regardless of whether you opt for a brick-built or fully glazed conservatory. uPVC doors and windows come with multi-point locking, ensuring top-tier protection, along with toughened glass, internal beading, and force-resistant hinges as standard.
Our conservatories are equipped with SMARTGLASS® technology, which not only provides excellent thermal insulation but also offers noise reduction properties. Our argon gas-filled windows and double-glazed doors keep the cold out and reflect heat back, helping to keep it warm during the winter months. We also offer solid conservatory roofs, or roof lanterns, for an extra layer of insulation.

When it comes to adding extra space and value to your home, there’s no better choice than a conservatory. Whether you’re looking to add extra living space, increase the value of your home, or simply make the most of your garden, our conservatories are the perfect solution.
Our wide range of conservatory styles, including both modern and traditional, are designed to complement the architecture of your home, no matter what your preferences may be. Choose from our extensive range of stunning designs, such as Victorian conservatories, modern lean-to, gable, t shape, p shade, Edwardian, solid roof, or Georgian conservatory.

FAQs about uPVC Conservatories Leicester
Do you need permission for a conservatory?
Generally, planning permission is not necessary for most conservatories, but we always recommend that you check whether planning permission is required. Most conservatories can be built under the “permitted development” rules, but this is subject to certain conditions. For example, conservation areas have stricter rules. Checking this will give you peace of mind and there’s also no risk of having your conservatory removed in the future should it be built illegally.
What is the process of building a new conservatory?
Building your new conservatory with Phair Windows is an easy and seamless process. In short, we:
- Design & CAD: We start by helping you choose and refine your bespoke conservatory design using advanced CAD.
- Site Preparation: We mark out and prepare the site, removing obstructions and digging footings.
- Base Construction: We build the foundations, lay the damp-proof course, concrete the floor, and construct the dwarf walls.
- Framework & Glazing: We then erect the uPVC framework and roof, followed by the installation of glass units and roof panels.
The job is not complete until you’re 100% satisfied with your new conservatory. You’ll also receive all of the relevant paperwork.
How big a conservatory can I have without planning permission?
The size of a conservatory that can be built without permission varies depending on factors such as location and whether it is a detached or semi-detached/terraced property. The maximum size is generally 30 square metres or less, and it should not extend further than the original rear wall by more than 4 metres for a detached house or 3 metres for a semi-detached or terraced property. Always verify with the local planning authority for any additional specifications.
What's the difference between a conservatory and an orangery?
An orangery and a conservatory are quite different. An orangery has a brick structure with some windows covering less than 50% of the walls and a glass roof covering less than 75% of the roof area. Whereas a conservatory is made up of at least 50% glass with a brick base and pitched glazed roof covering more than 75% of the roof area. This is the general rule, however, all styles of conservatories and orangeries vary from property to property.
Are conservatories safe and secure?
Yes, conservatories by Phair Windows are highly secure using the latest double glazing technology and locking systems. All of our conservatories are made with premium-grade materials and fitted with high-security locking systems to keep any possible burglars out.
What are the benefits of adding a conservatory to your home in Leicester?
Adding a conservatory to your home in Leicester offers several benefits. It increases living space, enhances the feeling of extra space, provides a beautiful connection to the outdoors, enhances natural light, adds value to your property, and creates a versatile room for various purposes such as dining, entertaining, or relaxation.

Professional, skilled, great communication from the on-site team - honestly, the best workmen I’ve ever had. They left the place tidy and neat. Thanks guys! They did a great job on a dreary, winter’s day with a smile. I love the new porch, which was a decent price. Honestly though, the sales guy Tom and the crew of Cal, Jake and Aaron were great. After having had a bad experience before with a different company, I’ll be using Phair Windows to replace my windows in the near future as well.
