Update: temporary closure of Energy Saving Trust's London headquarters
On Friday 9th March a fire broke out in the building of the Energy Saving Trust's London headquarters. Everyone was safely evacuated from the building and the fire was quickly contained. We are now established in two different offices nearby while refurbishment work takes place.
If you are visiting a member of staff based in London, please contact them to check their location. If you need to phone them, please use the switchboard number below as our direct lines are not currently working. All our email addresses are now working as usual.
