Energy efficiency and fuel poverty

​Households spending more than 10% of income on fuel bills to maintain a heating regime are considered to be in fuel poverty. Whether you rent or own your home, this information could help you save money. ​

If you use a pre-payment meter or are struggling with money problems the Government has agreed emergency measures with suppliers.
Options may include: 

  • Reviewing bill payment plans, including debt repayment plans 
  • Payment breaks or reductions in how much you pay 
  • Giving you more time to pay 
  • Access to hardship funds in some cases 

No credit meters will be disconnected during the outbreak.
Visit your supplier’s website or contact them for advice specific to you.
If you are struggling to pay for your gas and electricity bills or you get into debt, contact your energy supplier as soon as you can. They will work with you to agree a payment plan you can afford. 
There is also a wide range of local and national organisations that offer help and support:

Switching energy suppliers or tariff is one of the best ways to reduce your energy bills. You don’t need to own your home to switch, and doing so could save you hundreds of pounds a year if you are on an expensive standard variable tariff.

​Ofgem, the energy regulator, has advice on how to switch energy tariff or suppliers.​​​​​​​​​​​​​Link opens in a new window

There are many ways to reduce your energy bills, from changing your habits to getting a new efficient boiler installed at your property. These organisations can provide advice and may be able to provide funding towards home improvements:

Energy saving tips
  • ​When bulbs break, try replacing them with modern LED bulbs. These are much more efficient than traditional bulbs, and can save you money over time.
  • Switch appliances off, and don’t leave them on standby. This could save you up to £30 a year according to the Energy Saving Trust.​​​​​​​​​​​​​Link opens in a new window 
  • Draught proofing windows and doors can help keep more heat in and save you money. 
  • Turn your thermostat down by 1 degree, and give radiators a few centimetres more space by moving your furniture slightly. This can reduce your energy usage and make sure your home is heated more efficiently, lowering bills. 
  • Get a Smart Meter. This can help you understand where you’re using the most energy, so you can cut back in the right places to make savings. They also provide far more accurate bills.
To avoid a build-up of moisture in your home that could result in mould you need to both heat and ventilate the property. Try the following options:

  • ​Produce less moisture.
    Try keeping the lids on pans when cooking, drying clothes outdoors rather than on radiators, venting your tumble dryer outside, and avoiding using paraffin heaters or bottled gas heaters. 
  • Let the moist air out and the fresh air in.
    Extractor fans are an effective way to get rid of moist air and steam so that less condensation forms. When cooking or bathing, keep the kitchen or bathroom door shut and open the window so that the steam goes outside instead. 
  • Insulate and draught-proof your home.
    Warm homes suffer less from condensation so you should make sure your house is well insulated. This means insulating your loft to the recommended depth of 270mm, and your cavity walls (if your house has them and is suitable). Your windows and external doors should be draught-proofed, and you should consider secondary glazing if your windows are draughty. 
  • Heat your home a little more.
    While you don’t want to waste money heating rooms you don’t use, very cold rooms are more likely to get damp and mould.
