What can we do for you?

  • Advice on reducing energy use at home, included energy saving tip and how to use heating and hot water controls to save money
  • Advice and support on suppliers or tariffs including explaining statements, energy caps, standing charges and unit rates
  • Supporting with accessing the water discounts or Priority Services Register
  • Support with applications for energy or water debt relief
  • Advice and support to help apply for the installation of larger efficiency measures such as insulation and boiler upgrades
  • Referring you to other support organisations within your community if needed - such as food parcels, fuel vouchers, white goods
  • Delivering small efficiency measures, such as LED lightbulbs, draught proofing, powerdown units, CO alarms, warm kits, power cut kits and more!

If you use British Sign Language (BSL), we can provide free energy-saving advice via video call with a BSL interpreter.
