Upcoming Events

Our Open Eco Homes 2026 is now planned for 22nd September through to 18th October in Cambridge city and South Cambridgeshire.

Home Tours

We plan 10 new in-person and on-line tours. Highlights include external and internal wall insulation, solar panels, batteries, Home Assistant controls, EV chargers, heat pumps, rainwater harvesting and MVHR systems.

  • Mikhail, a visitor on a previous OEH tour, has now retrofitted his home and is opening it to show his air-to-air heat pump, solar and battery system.
  • Cambridge Retrofit will show progress on their deep retrofit on Greville Road.
  • Joe will show how he got a heat pump installed on a budget — just £1,000 cost after the £7,500 grant.

Talks

We are excited to reveal 4 talks following on from the successful “Get Ready for Heatwaves” talk at the end of June:

  • Retrofit & Next Steps — a retrofit for every budget, and no budget
  • Air Tightness — fabric first principles
  • Funding your home retrofit — grants and loans
  • Batteries — new cheaper technology and opportunities for bill reduction

This page will be updated as the tours and talks are finalised, follow our social channels to hear the latest updates.
