Lessons we are taking forwardEvery home is different

To achieve deep cuts every home is ‘hard to treat’

Every household is different

Lots of reasons not to do everything at once

Lots of factors affecting order of actions

Different people need different finance options

Lessons we are taking forwardValue of co-learning: home owners,

installers, advisers, planners, suppliers

Need right supplies and accessible info for trades too (marginal up-skilling, don’t patronise)

Installer has direct contact and sells best

Local outreach works well, but need offer for all

Intelligent programmes learn and flex
