Coordination with your retrofit assessor and retrofit coordinator
Ventilation upgrades to match the improved airtightness
Heating: heat pumps, controls and emitters where specified
Solar PV where it is part of the design
Resident liaison through a disruptive programme

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.

PAS 2035:2023 sets the whole-house retrofit process (assessment, coordination, design, installation and evaluation), and PAS 2030:2023 covers installation. Most government-backed retrofit schemes require both, with TrustMark lodgement.
