‘Retrofit’ is when a property is fitted with renewables or energy efficiency measures after it has been built. This helps to cut down on the amount of energy used to heat, cool or power the building

Adding energy efficiency measures to your home while you carry out other home improvements, like redoing a kitchen or bathroom, is a great way to minimise the cost and disruption of upgrading your home.

Why retrofit your home?

Retrofitting your home can help to lower your energy bills, make your home warmer and more comfortable, make your home healthier through improved indoor air quality and reduce your carbon footprint.

Britain’s 28 million existing homes are responsible for around 15% of the UK’s carbon emissions, according to the Committee for Climate Change. This is a major obstacle to hitting the government’s net zero climate goals. To reduce the UK’s carbon emissions, energy-efficient retrofits will need to be undertaken on the UK’s existing buildings at scale.

What are some typical retrofit measures?

Retrofitting can range from small activities such as fitting energy-efficient light bulbs to installing state of the art heating systems. Retrofitting measures include:

  • Loft insulation
  • Wall insulation (external / internal / cavity)
  • Under floor insulation
  • Double or triple glazed window and doors
  • Improved ventilation design
  • Reducing draughts, primarily around windows and doors
  • More efficient heating and hot water systems
  • Installing heat pumps or solar panels

Does my home need retrofitting?

Most homes have room for improvement!

Our free Energy Saving Devon Plan Builder can help you decide which measures will be most suitable for your home depending on your priorities.

What are the benefits of retrofitting?

Retrofitting your home can radically improve your comfort, energy use and subsequent carbon footprint, improve your health and reduce your bills.

Individual homes or building owners can contact their local Community Energy Group for advice on how to make their homes more energy efficient, healthier and more comfortable.

Is financial assistance available to me?

The cost of installing energy efficiency measures will vary depending on the size, age and existing thermal properties of your house. Ultimately, what you pay as part of a retrofit should be recouped in long-term energy savings.
