Air Source Heat Pump Technical Surveys
Property-focused technical survey information to help assess whether an air source heat pump approach is suitable and what needs to be considered before a system is specified.
Understand the property before the system is designed.
A heat pump is not sized simply from the EPC or floor area. A technical survey should consider the building fabric, room dimensions, heat loss, emitters, controls and practical installation constraints.
- Property construction and relevant fabric information
- Room dimensions and room-by-room heat-loss considerations
- Existing radiators/heat emitters and heating system
- Hot-water cylinder and controls considerations
- Outdoor unit location and practical installation considerations
- Electrical and other site information where relevant

Better information supports better system planning.
MCS guidance highlights the importance of a full property survey and heat-loss assessment before a compliant heat-pump quote and system design are finalised.
MCS heat-pump guidance
Current MCS guidance describes a full room-by-room property survey and heat-loss assessment as part of the heat-pump design journey. RETROSURV can help gather relevant property information before the installation design stage.
