Adding a conservatory is a great way of adding a light welcoming space to your home. It also allows you to enjoy your garden for longer periods of the year.

Conservatories are a great way to add additional space to your home and when they are well designed they can create a wonderful space that you can enjoy all year round.

Will I need planning permission for my conservatory?

Under new regulations that came into effect from 1 October 2008 adding a conservatory to your house is considered to be permitted development, not needing an application for planning permission, subject to the limits and conditions listed below.

  • No more than half the area of land around the ‘original house’* would be covered by additions or other buildings.
  • No extension forward of the principal elevation or side elevation fronting a highway.

  • No extension to be higher than the highest part of the roof.

  • Single-storey rear extension must not extend beyond the rear wall of the ‘original house’* by more than three metres if an attached house or by four metres if a detached house.

  • Maximum height of a single-storey rear extension of four metres.

  • Maximum depth of a rear extension of more than one storey of three metres from the rear wall of the ‘original house’* including ground floor.

  • Maximum eaves height of an extension within two metres of the boundary of three metres.

  • Maximum eaves and ridge height of extension no higher than existing house.

  • Side extensions to be single storey with maximum height of four metres and width no more than half that of the original house.

  • Roof pitch of extensions higher than one storey to match existing house.

  • No verandas, balconies or raised platforms.

  • On designated land* no permitted development for rear extensions of more than one storey; no cladding of the exterior; no side extensions.

Will I need building regulations approval for my conservatory?

Conservatories are normally exempt from building regulations when:

  • They are built at ground level and are less than 30 square metres in floor area.

  • At least half of the new wall and three quarters of the roof is either glazed or translucent material.

  • The conservatory is separated from the house by external quality door(s). Glazing and any fixed electrical installations comply with the applicable building regulations requirements (see below).

  • You are advised not to construct conservatories where they will restrict ladder access to windows serving rooms in roof or loft conversions, particularly if any of the windows are intended to help escape or rescue if there is a fire.

  • Any new structural opening between the conservatory and the existing house will require building regulations approval, even if the conservatory itself is an exempt structure.

Prices banded around by companies varies so much that it can seem almost impossible to decide which price offers greatest value for money.
