Coordination with your retrofit assessor and retrofit coordinator
Windows and doors, draught-proofing and airtightness details
Ventilation upgrades to match the improved airtightness
Heating: heat pumps, controls and emitters where specified
Solar PV where it is part of the design

How do we deliver it?

We do not treat a measure in isolation. If the design adds insulation and airtightness, we make sure the ventilation upgrade is in the same programme, because condensation is the most common retrofit failure.
