Conservatory prices

The price of a new conservatory or orangery can vary dramatically. The cost will depend on what type of conservatory you choose, how big it is and what materials it's made from.

But there are things you can do to keep the costs down and stay within your budget. We've worked with the Royal Institution of Chartered Surveyors (RICS) to bring you the average cost for three different sizes of conservatory, as well as the prices for basic and more complicated constructions.

We've also contacted conservatory firms across the UK, grilled experts and got the low-down from more than a hundred conservatory owners to find out how you could save and the key things you need to consider. 

Use the findings from our research to choose the right type of conservatory for your home and budget, and make sure you don't get caught out by any unexpected costs.
