asked Her Majesty's Government:

What is the definition of (a) a bedroom, and (b) a study in a residential property in relation to the home information pack.[HL4506]

From 1 August, owners of properties with four or more bedrooms will be required to compile a home information pack if they market their property for sale. A four-bedroom dwelling is one that is marketed and sold as having four bedrooms.

Energy performance certificates and home information packs will be phased in, starting with four-bedroom homes and larger properties and rolling out as quickly as possible to three-bedroom properties once sufficient energy inspectors are in place nationally and regionally to meet demand, taking into account market conditions.
