While new homes in Derby are now generating more energy than they consume, most of the houses we’ll live in by 2050 have already been built – many without modern energy-saving standards.

To meet climate goals, hundreds of thousands of homes across Derbyshire and Nottinghamshire will need to be retrofitted for greater efficiency.

​

Why retrofit?

 

Retrofitting means upgrading your home to improve energy efficiency, reduce heating costs, and replace fossil fuels (gas, oil, coal and wood) with clean, renewable energy.
 

Heat Loss Facts
 

• 40% of heat escapes through walls.

• 25% of heat is lost through the roof.

That’s why insulating walls and roofs is one of the most effective ways to cut energy use and lower bills. This ‘fabric-first’ approach ensures that when you're ready to install a low-carbon heating system like a heat pump, it will be smaller, more efficient, and cheaper to run.
