How Much Does a Conservatory Cost Per Square Meter?

How much does a conservatory cost to build?

Conservatories are a great way of adding extra living space onto your home, be it either an expansion of a pre-existing room or a while new multi-purpose room that you can use as anything from a study to a greenhouse. Because of their easily accessible materials and quick build times, conservatories are very affordable while also adding value to your property.

Per square meter, a conservatory costs around £1,000 – £2,000 per square meter, with that cost varying depending on the materials and additional hardware you want installed on your conservatory.
The price of getting a conservatory installed, however, tends to vary on a number of factors including the size of the structure, what materials you are having it built from, the style of the conservatory, the number of doors you want, the type of glass and more. The average cost of smaller conservatories usually starts around £2,000 – £4,000, while bigger conservatories can cost up to £8,000 – £10,000.

How much does it cost to replace a conservatory?

If you are finding that your conservatory is not giving you the same high quality performance that it once was, and is looking a little bit worse for wear after around 30 years (which is the average lifespan for a conservatory), then you may be considering getting a replacement conservatory fitted.

This usually costs around the same as getting a brand new conservatory installed, excluding the price of getting either the same company of a separate tradesmen to come demolish and take away your old structure. It is usually best to shop around, but you can also ask your chosen installer for your new conservatory whether they’d be willing to offer you a quote on the demolition and removal.

However, sometimes if your conservatory is underperforming it is not a completely lost cause. In fact, a conservatory will poor thermal efficiency is simply a sign that the roof of your conservatory needs replacing. A lot of heat can be lost through an old, poorly installed or damaged roof, and getting a replacement roof can often add years of life back onto your conservatory.

The most cost-effective option, being lightweight, easy to install and surprisingly sturdy. They were the standard roof to be fitted onto conservatories up until around 10 years ago, and while they aren’t as thermally efficient as some of the other roofs they are a great option for bridging between your old inefficient or broken roof and a new glass or solid roof.

Glass roofs are the most traditional out of all of the different roofing options, bringing in massive amounts of natural light into your conservatory and providing great views of the sky whilst remaining sturdy, weatherproof and thermally secure. Modern glass is used to ensure that warm air is trapped within your conservatory, preventing heat loss and saving you money on your heating bills. This classic look also improves the overall outward appearance of your property.

Lantern roofs are a contemporary roofing solution that combines the design and aesthetic of Renaissance Europe with the modern technological advances in double glazing manufacturing and materials. Available in a variety of different styles and colours, lantern roofs bring in a lot of natural light, while also giving added height to your room which creates the illusion of more space.

Solid roofs can transform your simple glass conservatory into a room that feels like a natural continuation of your property rather than an additional afterthought. Incredibly thermally efficient, they have a long lifespan and can remain solid and secure against even the worst kinds of weather the UK can throw its way. They can also come fitted with additional rooflights and skylights, meaning that you don’t have to compromise on the amount of natural light entering your property.

Like solid roofs, tiled roofs create a space that blends the boundary between your pre-existing property and your conservatory, with a room-like appearance that feels as if your conservatory has always been a part of your property. On the outside, a tiled roof can be made to either replicate or offset your original property’s roof by having similar tiles fitted. These tiles also come in several options, including slate, traditional or contemporary tiles made from different materials. For more information on tiled roofs, please contact us today.

Hybrid roofs are a great choice for if you want a conservatory that is both thermally secure and contemporary, with a hard-wearing solid conservatory roof interspersed with uPVC panels that mean that you get the best of both worlds in terms of thermal insulation, a room like feel and an excess of natural light. With an interchangeable panel system, your window panels can be installed anywhere along the roof so you can take full advantage of your conservatories position to give great views and capture sunlight.

Is a conservatory cheaper than an extension?

The line between a conservatory and an extension is often the case of how much of the structure is made up of windows, with a conservatory roof being around 75% glass and their walls being anything over 50% glass. An extension is pretty much anything under that percentage, with the rest of the structure being made up of brick. However, this distinction can make a lot of difference in terms of your bank account.
Although the price can be affected by how big the structure is, a conservatory is usually cheaper than a single storey extension with the same dimensions. Extensions tend to be more expensive because of the extra work that is often needed during their construction, costing between £14,535 and £72,000, however a conservatory can add just as much space to your property and will add just about as much value to your property that you spend; this means that, if you decide to sell your house on, you will end up earning your money back for your conservatory, if not a bit more.
