The Part L 2021 consultation process for England started in late 2019 with proposals released for new dwellings. A subsequent consultation on proposals for existing dwellings, including conservatories added to existing dwellings, ends on 13
th April 2021.
The Part L timetable for existing dwellings, including conservatories, is anticipated in accordance with the following timeline:
| Date |

| February to April 2021 |
Consultation on energy efficiency standards for work carried out in existing dwellings |
| December 2021 |
Publication of new Part L, Part F and overheating regulations |
| June 2022 |
Part L, Part F and overheating regulations come into force |
In the current version of Approved Document L1B, a conservatory with a floor area less than 30m
2 is exempt from the energy efficiency requirements. This is provided there is an appropriate thermal separation between the conservatory and dwelling and the heating system of the dwelling is not extended into the conservatory. Where these conditions cannot be met, then the glazed elements should meet the requirements for replacement windows and doors (referred to as controlled fittings).
