Building Regulations |
|
| |
Generally speaking conservatories/sunrooms on residential property are exempted under Building Regulations. |
|

Below are some of the Exemption Criteria - under the Building Regulations 1991 (as amended). These criteria must be met for a conservatory extension to be classified as exempt: |
|
| |
| a) |
The extension has a completely transparent or translucent roof. |
| b) |
The extension walls are substantially glazed. (Should not have more than 25 % of its wall area as brick work) |
| c) |
The extension has a floor area not exceeding 30m squared. |
| d) |
The extension is sited at ground level. |
| e) |
The extension is permanently separated from the remainder of the property by means of a door. |
| f) |
Any radiator within the conservatory is controllable. (If fixed heating installations are proposed, they should have their own separate temperature and on/off controls). |
| g) |
The glazing satisfies the requirements of part N, Schedule 1 (toughened/safety glass). |
| h) |
The extension does not contain any drainage facilities. (i.e. sink, WC, or washing machine) |
|

An example of where building regulation approval may be required is a Kitchen / Conservatory Extension . We suggest you contact your local council - explain your intentions - they will be able to give you more specific advice. |

As a further guide conservatories that require building regulation approval will need glazing of the highest insulation quality i.e. - Pilkington K Glass (low E) with argon filled units. |
