Conservatory cost guide

Building a conservatory is a great way to add space to your property and bring the outdoors into your home. In this guide, we look at the average conservatory cost in the UK to help you plan your budget.

Conservatories let in all the light from outside, allowing you to enjoy your garden from the comfort of indoors. And, where old conservatories previously had a bad name for being too hot in the summer and too cold in the winter, modern conservatory materials offer comfortable temperatures all year round.

For the purpose of this guide, we’ve included prices for building a 3.5m x 3.5m conservatory. If you’re looking to build a smaller or larger conservatory then that will obviously affect the total price you pay.

How much does a conservatory cost?

There are a number of types of conservatory, with three of the most popular in the UK being lean to conservatories, Victorian conservatories and Edwardian conservatories. The style conservatory you choose will affect the cost, as will the material it’s made from.

A lean to uPVC conservatory will cost around £10,250, whereas the average cost for a lean to wood conservatory costs around £13,500.

If you’re planning to build a Victorian conservatory then the average cost for uPVC is £12,750, and for wood, you’re looking at a price of about £16,750.

An Edwardian lean to conservatory costs in the region of £11,250 for uPVC, or about £15,750 for wood.

Before starting any conservatory project, we recommend speaking to your local conservatory specialists to get their professional advice and accurate quotes for the job.

cost of conservatoryFactors affecting the cost of a conservatory

The main factors that will affect the price of your conservatory are:

  • Any ground prep work needed
  • Additional features (e.g. underfloor heating)
  • Type of glazing

Types of conservatory

Lean to conservatory costs

The name is a slight hint as lean to conservatories are constructed of three walls attached to the side of your house. They traditionally have a sloping roof and tend to be the cheapest and easiest type of conservatory to build.

The average cost of a lean to conservatory is £9,000 to £14,250.

Victorian conservatory costs

A Victorian conservatory has a pitched roof and rounder frontage and is one of the most common types of conservatory that you’ll see in British homes. They’re usually available in a range of materials and finishes to suit a variety of styles.

For a Victorian conservatory, the average price will fall in the region of £12,000 to £17,500.

Edwardian conservatory costs

Edwardian conservatories are similar to Victorian conservatories but have a flat frontage instead of a rounded one. You’ll find that the prices of Edwardian conservatories are roughly the same as Victorian conservatories, with similar choices of materials and finishes.

The average cost of an Edwardian conservatory ranges from about £10,500 to £18,000.

Orangery costs

An orangery is a hybrid of a conservatory and an extension, combining brickwork with glass. The more sturdy construction means that orangeries generally come at a higher cost than more traditional conservatories.

The average cost of a 16m2 orangery is about £32,500. If you’re interested in building an orangery, check out our orangery cost guide for more price information.

  • Always double-check with your local planning office to see if you need any special permissions.
  • Shop around for fair and competitive conservatory costs.
  • Always hire tradespeople with relevant experience and ask to see previous examples of their work.
