Our local primary schools are facing rising energy bills — money that could be better spent supporting pupils and teachers.
At Selce (South East London Community Energy), where I work, we’re launching a community share offer to fund an LED lighting upgrade at a local primary school. By replacing old lighting with efficient LEDs, the school can significantly reduce its electricity use, cut carbon emissions, and lower its energy bills.
The savings can then go back into the things that really matter: education, resources, and support for students.
Community shares are a way for local people to invest in projects like this — helping schools save energy while supporting community-led climate action.
If you’re interested in supporting a project that benefits both our community and the climate, you can find out more here:

And please feel free to share with anyone who might be interested.

Looking for insulation in walls. The first one had some mineral wool in it above dpc level. The second one didn't have any insulation but plenty of wildlife, spider webs and old wasp nests. Might need to improve that wall a bit. Good to use the borescope to see what's going on inside them.

Then used this information to update the whole house plan for the property.

Looking for thermal bridges in this house in Dulwich. It's getting a bit warm for the thermal camera but it still shows some fabric weaknesses in this wall.

Surprised to be out on a Friday night learning about automations and AI agents. The pizza and wine made it easier. Thanks Sonia from for the help with the automations and for organising.

On the way back from a Whole House plan retrofit survey. Used the Flir thermal imaging camera and found this cold patch in the extension. Some inconsistency in the loft insulation I think.

This is a great project in Lewisham South London where i made a whole house plan with the owners, and we have installed phase one of the works. The wood fibre internal wall insulation came from and was installed by Richmond Plastering

What causes overheating in your home and how to reduce it.

Cooling Your Home: Smart Retrofit Strategies How to find sources of overheating in your home and how green roofs and natural insulation can reduce it.

A green roof I made in Camberwell, starting to develop and flower in the spring. Assuming all rain hasn't ended and in a year or two this will be a mad of wildflowers and plants.

Had a good visit to a green open house in Ilford today. Wood fibre external wall insulation at the rear, loft and floor insulation and solar panels. Then there is the coolest DIY green roof with planted footwear! Thanks very inspiring.

The wood fibre is all getting plastered to a finish on our project in Lewisham. The weather means it may be more useful in reducing overheating in the summer.
