How to Reduce Energy Bills and Keep on Top of Council Tax

If you are looking for practical ways to reduce energy bills, you are not alone. Millions of UK households are under pressure from rising gas and electricity costs, and the knock-on effect on other priority bills like council tax can be serious. When energy costs eat into your monthly budget, council tax arrears can build up quickly. This guide covers straightforward steps you can take right now to cut your energy spending and protect your finances in 2026.

Why Energy Bills Matter for Council Tax Payers

Energy costs are one of the biggest household expenses in the UK. According to Ofgem, the energy price cap for Q1 2026 stands at approximately 1,568 pounds per year for a typical dual-fuel household. That is a significant chunk of any household budget, and when energy bills spike, something else often gives way. For many people, that means falling behind on council tax.

Council tax is a priority debt. Your local authority can take enforcement action, including sending bailiffs, if you fall into arrears. Keeping your energy costs as low as possible gives you more breathing room to stay on top of council tax payments and avoid enforcement action. If you are already struggling with council tax arrears, getting your energy bills under control is one of the first steps towards financial stability.

Switch to a Better Energy Tariff

One of the quickest ways to reduce energy bills is to check whether you are on the best available tariff. Many households sit on their supplier’s standard variable tariff without realising they could save hundreds of pounds a year by switching.

Use a price comparison service like Ofgem’s accredited switching sites to compare deals. Since the energy market opened up again after the crisis years, there are fixed tariffs available that sit below the price cap. Even a small saving per month adds up over the year, and that money can go towards keeping your council tax payments current.

If you are on a prepayment meter, you may be paying more than direct debit customers. Ask your supplier about switching to a smart meter, which can also help you track usage in real time.

Reduce Energy Bills With Better Insulation

Heating your home accounts for around 55% of your total energy bill, according to the Energy Saving Trust. Poor insulation means you are literally paying to heat the outside air. Improving your home’s insulation is one of the most effective long-term ways to reduce energy bills.

Loft insulation should be at least 270mm thick. If yours is thinner or missing entirely, topping it up could save you around 355 pounds a year according to 2026 estimates from the Energy Saving Trust. Cavity wall insulation can save a further 295 pounds annually on a typical semi-detached house.

The Great British Insulation Scheme (GBIS) is still running in 2026 and provides free or subsidised insulation for eligible households. Check the GOV.UK website to see if you qualify. If you are on a low income or receive certain benefits, you may also qualify for the Energy Company Obligation (ECO4) scheme.

Simple Daily Habits That Cut Costs

You do not need to spend money to start saving. Small changes to your daily routine can make a noticeable difference:

  • Turn your thermostat down by just one degree. The Energy Saving Trust estimates this alone could save around 145 pounds a year.
  • Switch off lights when you leave a room. LED bulbs use a fraction of the energy of older halogen or incandescent bulbs and last up to 25 years.
  • Avoid leaving appliances on standby. The average UK household wastes around 60 pounds a year on standby power.
  • Only boil the water you need. Overfilling the kettle wastes energy every single time.
  • Wash clothes at 30 degrees. Modern detergents work just as well at lower temperatures, and you will use significantly less energy per cycle.

None of these require any upfront cost, and together they can take a meaningful amount off your annual energy spend.

Upgrade to Energy-Efficient Appliances

If your washing machine, fridge freezer, or tumble dryer is more than ten years old, it is almost certainly less efficient than a modern replacement. Look for appliances with an A or B energy rating when the time comes to replace them.

A new A-rated fridge freezer, for example, uses roughly half the electricity of a ten-year-old model. Tumble dryers are particularly expensive to run, so consider using a clothes airer or outdoor line when possible. If you do need a dryer, heat pump models use up to 50% less energy than condenser types.

You do not have to replace everything at once. Prioritise the appliances you use most and factor energy running costs into your buying decision, not just the sticker price.

Draught-Proofing and Double Glazing

Draughts around windows, doors, and floorboards let cold air in and warm air out. DIY draught-proofing is cheap and straightforward. Self-adhesive strips for doors and windows cost a few pounds from any hardware shop and can save around 45 pounds a year.

If your home still has single glazing, upgrading to double or triple glazing makes a significant difference. The upfront cost is higher, but the long-term energy savings, combined with a warmer, more comfortable home, often justify the investment. Some local authorities offer grants or interest-free loans for energy efficiency improvements, so check with your council.

Get Help With Energy Bills If You Are Struggling

If you are finding it hard to pay your energy bills, there is help available. The Warm Home Discount Scheme provides a 150 pound discount on electricity bills for eligible low-income households. The Winter Fuel Payment and Cold Weather Payment also provide additional support during colder months.

Contact your energy supplier directly if you are falling behind. They are required by Ofgem to offer you a payment plan you can afford. You can also get free advice from MoneyHelper or StepChange, both of which can help you create a budget and deal with debts.

If your energy debt is part of a wider problem with household bills, including council tax, it is worth looking at a formal debt solution. Our guide to managing debt repayments explains the options available to you.

How Reducing Energy Bills Helps You Stay on Top of Council Tax

Every pound you save on energy is a pound that can go towards keeping your council tax payments up to date. Council tax is collected in ten monthly instalments (April to January), so even a modest monthly energy saving of 30 to 40 pounds can cover a significant portion of your council tax bill.

If you have already fallen behind on council tax, do not ignore it. Contact your local authority as soon as possible to arrange a payment plan. You may also be entitled to a council tax reduction or a council tax support scheme discount, depending on your income and circumstances.

The key is to take action early. The longer council tax arrears go unpaid, the more likely it is that your council will pass the debt to enforcement agents. Our guide on your rights when dealing with bailiffs explains what they can and cannot do.
