Lean to conservatory cost guide
Lean to conservatories get their name from their appearance of ‘leaning’ against the house, but you may also know them as sun rooms. Installing one is just like adding an extra room onto the side or back of your home.

The construction of a lean to conservatory is usually simpler than other types of conservatory, consisting of a single sloped roof and walls which join to the house. This kind of conservatory is a good option for homes with limited space available, or where there is a restricted height under the eaves (such as in a bungalow) as they can have a shallow pitched roof.

Average cost of lean to conservatory
The average cost of a lean to conservatory depends on a number of different factors. The biggest influence on cost is the size of the conservatory and the type and material of the roof. Tiled roof conservatories tend to be the most expensive, and polycarbonate roofs the cheapest.
How much does a lean to conservatory cost?
Depending on your taste for materials and size preferences, a lean to conservatory can cost anything from just over £8,000 to more than £22,000.
When you get quotes for a new conservatory, the cost will usually include the groundworks and base, walls and frames, roofing, glazing and any building work to the aperture of your home. It may also cover insulation and any finishing work such as plastering or painting.
Small lean to conservatory cost
When cost is a concern, go small. Adding a small lean to conservatory can be an affordable way to add some extra indoor/outdoor living space to your home, as well as letting light in and potentially adding value to your home. Even a relatively small 3m x 3m lean to conservatory can give you a good amount of extra space.
What other factors can affect lean to conservatory costs?
Finishing touches such as flooring, extra insulation, decorative glass, extra-thick glazing and furnishing can all add to the cost of lean to conservatory installation.
FAQs
Do I need planning permission for a lean to conservatory?
Conservatories generally fall under the category of ‘permitted development’, which means that you shouldn’t need planning permission to install one. However, there are exceptions. For example, you may need to seek permission if you’d like a lean to conservatory with a floor space larger than 30 square metres, or if your property is on designated land. If unsure, seek advice before installing your conservatory.
Will a lean to conservatory add value to my house?
A well-built, decent quality conservatory should pay for itself when it comes to adding value to your house. But a high-end conservatory can contribute even more, potentially adding up to 10-25% more in value than you paid for it.
Do I need an accredited installer?
You should always ensure you use a trained and qualified conservatory installer, preferably one who is FENSA or DGCOS registered.
