Recent updates to UK Building Regulations have introduced stricter guidelines for constructing conservatories, primarily to enhance energy efficiency and address climate change concerns. These changes have led to misconceptions about a potential ban on conservatories. Here, we explore the rumours around this ban and clarify:
The answer is no. They are not. However, there are increased regulations around them, especially regarding new properties. Let’s explain why conservatory extensions are still permitted and the reasons behind the new restrictions.
Contrary to some reports, conservatories have not been banned in the UK, and there is no plan to ban them. They do need to be more sustainable in their build and finish, intended to be used for a minimum of 10 years and carefully planned to meet the stricter planning regulations introduced in June 2022 and updated in 2024. In summary, while recent regulations have introduced specific requirements to improve energy efficiency and prevent “unwanted solar gain”—excessive heat accumulation during warmer months that may lead to overheating, no conservatory ban exists. The restrictions vary between existing and newly built properties, which is something we guide our clients through as conservatory specialists – but we recommend you seek advice to see what applies to your property. With thoughtful planning and adherence to the guidelines, homeowners can still enjoy the numerous advantages timber conservatories offer.
The rumour arose in 2022 after UK media coverage, particularly coverage on a popular morning television chat show discussing the hypothetical topic of whether there should be a ban with an anti-new-conservatory campaigner, who completed her interview while sitting in her own conservatory. Then, when new rules were introduced in June 2022, there was a lot of misunderstanding about the new regulations, leading to further rumour-mongering, confusion, and additional coverage from two major UK news outlets about hypothetical impacts on window and conservatory limitations. Once again, when these rules were updated in 2024, the rumours and confusion about the regulations once again came together and planted the seed for further rumours.
The updated regulations for new conservatories in 2024 focused mostly on making conservatories better for the environment, ensuring they are more energy efficient, better insulated, and more sustainable in their build, such as showing the use of recycled or eco-friendly materials, a great example being durable timbers like Accoya. Also, the previous four-year rule, which applied to most types of home extension, was replaced with a ten-year rule, meaning that the new conservatory must demonstrate a minimum of ten years of continued purpose rather than four. Essentially, they need to be built better to last for longer. There are also some differences between new-build and existing properties, which are covered below.
Despite these regulatory changes, conservatories remain a popular home addition due to four significant benefits: Additional living space, more natural light, increased property value and contemporary design updates to modify your home. Let me expand further on each of these:
If a conservatory solar gain is something you are still concerned with, we have seen our clients choose other similar alternatives, such as an orangery extension, a garden room with a pitched tiled roof instead of glass or even a standard extension with full-width bifold doors and full height feature windows. To delve deeper into these alternatives, an orangery enables you to open the house up. It uses a roof lantern for improved sunlight to radiant your space and can deliver better energy efficiency and a higher property value than a conventional conservatory. Still, a garden room with a pitch and tiles roof instead of a glass roof will also give you a complete open-window view of your surroundings and provide better energy efficiency and a lower U-value for improved insulation all year round. But if space is your main priority over appearance and style, then a traditional extension with features such as bifolds to open your space to the outdoors has fewer windows than a conservatory, so it will reduce your overall solar gain.
Sunroom Extension IdeasWhile recent regulations with conservatories have introduced specific requirements to ensure energy efficiency and prevent overheating, conservatories are not banned. Instead, they are a more considered extension that works more harmoniously with the environment and your home. A radiant space that now must be built to last longer and enjoyed as a more permanent extension of your home. With thoughtful planning and adherence to the guidelines, homeowners can continue enjoying their numerous advantages, especially the increased greener benefits timber conservatories offer.
