Most of the products in this industry are bespoke (made to measure), making it difficult to set a price as the dimensions and material are always changing.

Here are only some of the factors that change the price:


  • Material of frame (timber, PVC-U, aluminium, etc.)
  • Size of frame
  • Size of glass
  • Style of window (flush, casement, French, tilt & turn, vertical sliding)
  • Colour (standard colours like white and brown are cheaper than other colours e.g. grey)


  • Material of door (timber, PVC-U, aluminium)
  • Size of glass in door (any pattern in glass will also increase price)
  • Style of door (composite, bi-fold, patio, fire door, French)
  • Colour (standard white is cheaper than other colours)


  • Planning & building regulations
  • Size of conservator/orangery
  • Amount of brick work wanted
  • Amount of windows
  • Style of doors (patio, French etc.)
  • Type of roof (solid roof, PVC roof, etc.)
  • Any plastering you may want done

These are not all of the factors that determine the price of your installation, however they are the most prominent ones.
