When planning a new conservatory, many people get confused about the type of door they must have between the home and the new addition, or whether a door is even necessary at all. Hopefully this short blog will clear that up by addressing some of the myths about house/conservatory doors.
1. You must have a door. False.
Most conservatories are exempt from most parts of the Building Regulations provided they keep the external grade separating doors. Should you wish to renew the doors with newer ones, then the doors have to comply with part L of the Building Regulations even though the conservatory doesn’t. A FENSA or CERTASS registered window and door installer (most conservatory installers have these accreditations) will help you with this. If you decide you don’t want a door between the conservatory and your home, then a full Building Regulation application is needed – the total building needs to comply. Moreover, you may need to upgrade the existing insulation in the rest of the home to offset the heat loss through the conservatory, so that the new home+ conservatory are no worse from a heat loss point of view than the existing property. A SAP calculation is usually undertaken by a specialist surveyor
2. It is stipulated by building regulations that one must install a door of 'exterior quality'. A conservatory is only exempt from Building regulations only if there are separating doors. Should those doors be removed, the conservatory requires Building Regulation approvals.
