Greening social housing

Helping Birmingham City Council deliver the largest social housing tower block energy refurbishment programme ever under one contract.


The very latest energy-saving technologies are being installed in up to 885 homes, cutting fuel bills for over 2,000 low-income residents. The 19 Towers project is a partnership between Birmingham City Council and Carillion under the Birmingham Energy Savers Framework.

Smart communal heating systems using EcoPod technology, external wall insulation, windows and reroofing, combined with aesthetic upgrades are estimated to deliver over 60,000 tonnes of CO2 savings, or up to £400 per property in annual fuel savings.

From the outset we were advised by Western Power that mobile generators were needed to deal with the demands of the project. Generators produce significantly more CO2 than mains electricity and reduce air quality in the local areas through higher levels of nitrogen oxides (NOx) and particulate matter. They are also a source of constant background noise for neighbouring residents.

Keen to find a solution to the generator challenge, our services engineering team negotiated with Western Power to switch from 26 generators to mains electricity. As well as direct carbon and pollution benefits, the switch has avoided transportation of fuel to sites and a reduction in the project’s embodied carbon. The initiative has saved over £200,000 of additional margin, contributing to a total of £1.2 million delivered across the whole project. Further savings were achieved through value engineering some elements of the scheme, as well as better buying with our supply chain.
