Leaders in sustainable retrofitting solutions

What is ‘retrofitting’?

Retrofitting is the process of updating or modifying existing buildings so that energy consumption and emissions are reduced. Retrofitting can include the installation of a new building technology, replacing an existing fabric, or a combination of various measures; designed to improve energy efficiency and reduce demand. Thus providing warmer, more comfortable spaces with lower fuel bills.

Approximately 24 million homes need retrofitting to deliver the UK government’s commitment to net zero by 2050. Our homes, amongst the worst insulated housing stock in Western Europe, are responsible for over 25% of all Co2 emissions.

Tackling climate change whilst helping households and businesses reduce their energy bills by installing renewable and energy efficient measures.

Why is retrofitting your home important?


CO2 emissions from buildings must reach zero by 2050 for the UK to achieve an overall ‘Net Zero’ economy. To meet the UK Government’s climate change targets, we must retrofit all homes to an EPC band C or above.

To do this by 2050 at the latest, we need to retrofit 2450+ home per day, 7 days a week for the next 27 years.

The poor state of UK homes is a major factor in the energy crisis. Properties are losing heat through poor glazing, uninsulated walls and lofts, old heating systems and draughts.

A national retrofit approach will create thousands of jobs in every part of the country, protect our environment, and reduce energy bills in the years to come as part of a more prosperous, sustainable society.

We are working with local authorities, social housing landlords and policy makers to tackle the challenge head on.

Retrofitting is a complicated business because it’s not a ‘one-size-fits-all’ approach. Every property is different.
