Home Energy Efficiency

The Vale of Glamorgan Council supports Welsh Government's aim to tackle fuel poverty and poor energy efficiency in homes.

Project Zero is the Vale of Glamorgan Council’s response to the Climate Change Emergency. It brings together the wide range of work and opportunities available to tackle climate change, reduce the Council’s carbon emissions to net zero by 2030 and encourage others to make positive changes to support Project Zero at home. 





Homes that are energy inefficient (with an Energy Performance Rating below a C) will be harder to keep warm, have higher energy bills, and pump more CO2 into the atmosphere compared with their more efficient neighbours.


Improving your home’s energy efficiency through insulation and renewable energy technologies can deliver a variety of benefits to you as well as our planet.



  Benefits to you:

  • Significantly reduce heat loss

  • Reduce your energy bills

  • Keep you warm in winter, and cool in summer

  • Lower your carbon footprint

  • Improve your property's Energy Performance Rating (EPC) making it more attractive to buyers

  • Improve the comfort of your home and prevent damp




Simple ways to use less energy and save on your energy bills: 


  • Turn your thermostat down 1 degree
  • Switch the lights off in the rooms you don't utilise and use energy saving bulbs
  • Don't leave things on stand-by
  • Only fill and boil the kettle with the water you need
  • Use washing machines and dryers to full capacity unless you have half load settings
  • Don't leave taps dripping, especially hot water taps 
  • Close doors to keep heat in rooms

Keeping warm is vital, particularly for older people at home.  Age UK recommends layering up and keeping active at home and the Vale of Glamorgan Council has developed a Warm Spaces Scheme with a network of inviting warm community spaces bringing people together this winter at no cost.  What's more, the Council is also providing useful information and advice on Cost of Living Support


Measures that can be put in place to help you stay warm at home and lower your energy bills: 


  • Insulating your roof, floor and walls
  • Draught-proofing windows and doors
  • Upgrading your heating system to an energy efficient boiler or a heat pump 
  • Installing double or triple glazing
  • Using renewable sources of energy, such as solar power
  • Check the EPC rating for your home or have one carried out to get personalised recommendations
  • Ask your energy provider to fit a SMART meter to help you manage your energy usage and costs



Supporting fuel poor homes and those most in need:

The Nest Scheme offers a range of free, impartial advice and, if you are eligible, a package of free home energy efficiency improvements such as a new boiler, central heating, insulation, or solar panels.  This can lower your energy bills and benefit your health and wellbeing.
