What factors have the biggest influence on the cost of a new conservatory?

The impact of construction materials & visual styling

Material Type

What the frames are built from

If we are not counting special offers or time sensitive discounts, then the material the conservatory frame is manufactured from it can make quite a difference to the price.

The most popular material would likely be uPVC. This lightweight vinyl polymer is known for its' light weight durability and relatively low production costs. The multi-chambered frames used these days have excellent thermal properties being an effective barrier to both cold and heat transfer.

Timber of any kind is a natural insulator and does not transfer heat easily. Thus it is more than suited for use in a conservatory. However, one of the drawbacks of timber is that, if not treated properly, it can expand or shrink during long dry or wet periods. Having said that, if you look after the wood, it can last for decades.

Two kinds of timber are especially suited to conservatories, and they are hardwood or engineered wood. African hardwoods such as "idigbo" look a lot like mahogany and don't cost as much. Engineered wood is very stable, has a lot less trouble with expansion and contraction and can be "worked" into all kinds of shapes also making it an ideal candidate for use.

Type of conservatory

All conservatories are not equal, when it comes to price. For example, a Victorian conservatory will cost more than an equivalent sized lean-to and that is simply down to design elements. The biggest differences, in this particular example, would be that the lean-to conservatory is typically a simple rectangle with a single sided roof and the Victorian is a faceted structure with a many sided roof - more complex work means more cost.

Size of the room

It's not a secret, a bigger room will use more materials and take longer to build and this will obviously translate into an increased price. Large conservatories could also need to have planning permission to be granted prior to construction, which is another expense. If your proposed extension exceeds the limits for being a "permitted development" then you will have to deal with the local planning department.

Visual Styling

The finishing touches to your conservatory

green divider

Settling upon a general design that you like is the first part of the story, the second is choosing the finishing touches. Making the room reflect or contrast the appearance of your house can be easily be done by adding or removing one or more features, but they have a cost impact.

For example, going for coloured uPVC instead of white could add 5% to 15% to the cost of the frames themselves (not to the overall price).

Here are some things to consider:
  • Opening window sections - some suppliers make a charge
  • The door choice - French doors / bifold doors / Sliding doors
  • Specifications for glazing -  toughened or laminated. Sealed units 6 to 28mm width.
  • Energy ratings for glazed sections - A+ to G (Lower than C does not meet UK building reg's)
  • Coloured frames for uPVC have an added cost
  • Wooodgrain surfaces for uPVC have an added cost
  • The quality of your window & door furniture - handles, locks etc.
  • The type of roof - tiled, glass or poly-carbonate
  • Additional brickwork or masonry - adding dwarf walls, solid pillars or columns
  • Overall size - if you "go big" will you require planning permission?
  • Preparation of ground - is the area flat and clear or is it sloping and uneven

When you get a written quote, it should specify exactly what is included in the cost.
