"Under new regulations that came into effect from 1 October 2008 adding a conservatory to your home is considered to be permitted development."

So you’ve decided on your new conservatory and can envisage yourself relaxing in the sunshine, reading the newspaper and looking out over the garden, the next step is hiring the builders, and of course, checking whether you need planning permission.
Planning permission is mind-boggling for most of us, and if we’re honest, a little inconvenient. We’ve probably all got a friend or family member who had a loft conversion built and then went on to have endless disputes with a neighbour.
But this isn’t always the case! Your dream conservatory isn’t too far away!

Planning Permission for Conservatories

The Planning Portal is an online resource for planning and building regulations. It is a great first port of call when considering building work in England and Wales.

According to the Planning Portal, adding a conservatory to your house is permitted and does not need planning permission in England. That said, it must abide by the following guidelines:

1. The extension should not cover more than half the area of land around the original house.
2. The extension is not on the principal or side elevation facing a highway.
3. The extension is lower than the highest part of the roof.
4. If the conservatory is a single-storey rear extension, it must not go beyond the rear wall of the original house. It must not extend more than three metres if it is an attached house, or by four metres if it is a detached house.
5. The maximum height of a single-storey rear extension is four metres.
6. An extensions that is greater than one storey must not extend beyond the rear wall of the original house by more than three metres. Neither must it be within seven metres of any boundary opposite the rear wall of the house.
7. The maximum eaves height of the extension must be within two metres of the boundary of three metres.
8. The Maximum eaves and ridge height of the extension must be no higher than existing house.
9. Side extensions must be single storey with maximum height of four metres, and with a width that measures no more than half that of the original house.
10. The roof pitch of extensions should be higher than one storey to match the existing house.
11. There must be no verandas, balconies or raised platforms.
12. On designated land, there is no permitted development for rear extensions of more than one storey. There must be no cladding of the exterior and no side extensions.

The list of twelve guidelines above does not take into account all of the rules from the neighbour consultation scheme, but does give a good idea as to what conservatories are accepted without planning permission.

However, before you have your conservatory built (even though you have read this blog and visited the Planning Portal website), it is highly necessary to find out whether you need planning permission for your specific extension. Extra time spent now will save a lot of hassle in the future, and you want to enjoy your new conservatory (rather than battle with the neighbours!).

Other Popular Planning Permission Questions

It's not just conservatories that require planning, in fact, any property development that is an addition to the existing property will be subject to regulations. Other popular questions people ask include

Do you need planning permission for an Extension
The answer to this is yes, however if the extension falls within standard guidelines where the extension does not exceed ccertain heights / dimensions and does not impede on light to surrounding properties then permission may not be required. Building regulations will generally apply if you want to build an extension to your home.

Do you need planning permission for an Orangery
An Orangery is similar to a conservatory, the style varies but the typical development factors are the same. If an Orangery falls within the accepted permitted development guidelines like the ones above for a Conservatory then planning will not be required.

Building Regulations

Building regulations will apply if you are considering a home extension. Conservatories are normally exempt from building regulations when they are built at ground level and have a floor space of less than 30 square meters. Other regulations include:

  • The conservatory / structure should be seperated from the house by external walls, doors and/or windows.
  • The structure should house an independent heating system with temperature on/off controls.
  • Fixed electrical installations should comply with the applicable building regulation requirements.
