Conservatories are an extremely popular addition to any kind of property, but they sadly do not last forever.

A uPVC conservatory typically has a lifespan of between 25-30 years, with additional work often needed past that point in order to keep it up to date in both appearance, security and thermal performance.

So, often homeowners are looking out for ways of replacing a conservatory or renovating it into a far longer-lasting structure.

Extensions, being predominantly built from brick, can last for almost as long as the property it is attached to and can be a great, more permanent alternative to a conservatory; but what do you need to do in order to upgrade your conservatory into one?

The definition of a conservatory is a structure that is more glazing than solid walls, including 75% for the roof and over 50% for the walls. Extensions on the other hand is anything below that percentage, meaning that you can still bring in a lot of natural light and ventilation into your space even without it being a conservatory.

However, extensions often require planning permission, which conservatories are typically exempt from, which can lengthen the time of an installation and cost you more money in fees; but extensions can also be exempt if their structure is within certain parameters, such as being under 30m2 and being a single storey.

Can I convert a conservatory into an extension?

Getting a brand new extension can often involve buying in materials, hiring project managers and surveyors and sinking months of your time into planning and overseeing the construction.

However, if you don’t want to replace your pre-existing conservatory with a brand new extension and would rather find ways of transforming your conservatory into one via smaller changes, then you can actually begin that process by fixing a new roof onto your conservatory.

A lightweight solid roof is a great way of blending in your conservatory into the design of your original property, with a tiled roof mimicking the tiles of your main roof and looking like a natural continuation of the house both inside and out. On the inside, this solid roof will provide better insulation than a glass or poly carbonate roof, while also allowing for additional sky and roof lights to be installed so that you don’t miss out on natural light.

How much does it cost to replace a conservatory?

If your conservatory is worse for wear, you may want to get it removed and replaced with a brand-new extension. Demolition and removal costs aside, which you may have to contact local tradesmen to help you with, the cost of this replacement extension is going to be around the same price as a typical extension installation.

This price can vary depending on whether you are hiring a company to install it, if you are sourcing the materials yourself and where from, if you are your own project manager or if you are hiring in, and also your own design specifications such as size and what windows and doors you are having installed.

aluminium lantern roofs

How much does a conservatory roof conversion cost?

As mentioned above, fitting a new roof onto the structure of a pre-existing conservatory is a great way of prolonging the lifespan, value and performance of your conservatory extension. Poly carbonate roofs were the standard up until recently, and they have been proven many times over to be less than quality in thermal efficiency and in overall hardiness, so it may very well be the case that your conservatory is losing much more of your heating than you realise.

There are two main options when it comes to getting a new conservatory roof, that being a Lantern Roof or a Solid Roof:

Made up of glazed glass panels, either with uPVC or slimline aluminium frames.

Available in a number of styles, dictating how many bars are across the window sections and how big each window section is. They allow in excess natural light into your property and can be fitted onto flat or raised pre-existing conservatory roofs.

Also called a ‘Tiled Roof’, this roofing option mimics and replicates the roof of your main property in both appearance and features.

With amazing insulation, they are light enough to be able to fit onto your uPVC conservatory structure without risking its structural integrity. They can also have roof lights and skylights installed to allow for more natural light and for extra ventilation.

All in all, a replacement roof for your conservatory, while varying in terms of what kind of roof you are getting and what kind of materials you are using, typically only costs between £2,500 and £20,000, with solid roofs being the more expensive option.

Do you need planning permission to change conservatory into a room?

Planning permission can be somewhat of a hassle to get done, but it is often a necessary requirement when having structures installed on your property, including extensions.

However, there have been recent changes in legislation, allowing for more leniency when it comes to what structures require planning permission and which ones don’t. For example, as long as your conservatory or extension roof does not exceed the height of your original property, you do not have to get planning permission to get one installed.

Additionally, there are certain size regulations in place that mean that; if your extension option is under 30m2 in floor size and is a single storey, then you may also be exempt from planning permission.
