Older Manchester terraces leak heat through solid walls, suspended timber floors and original sash windows. Homeowners wanted carbon and comfort improvements but found the mainstream installer market unwilling to take on the whole-house complexity.
What they did
Carbon Co-op coordinates a Retrofit Coordinator, an assessor, a designer and trusted contractors around each home. Most projects combine fabric upgrades (internal or external wall insulation, floor insulation, airtightness), heat recovery ventilation and a fabric-first approach to heating; some progress to a heat pump once heat loss is reduced. The programme follows PAS 2035 and publishes case studies for each home.

Measured means monitored data from the site. Reported is the publisher's stated figure. Modelled is a target or design figure rather than an outcome.
What we take from it
- A Retrofit Coordinator is the difference between a coherent project and a stack of disconnected installations.
- Fabric work comes before heating kit. Skipping that order is the single most expensive mistake in retrofit.
What the source does not tell us
- The programme publishes project descriptions rather than long-term monitored energy data, so 'how much it saved' varies per home and per source.
