Cheap energy deals have disappeared over the last several months so it's not a good time for most people to switch energy provider.
If you haven't switched your supplier or tariff recently, or were moved to a new provider when yours closed, you'll probably be paying out-of-contract rates (also known as a variable or default tariff). Historically, these haven't been very good value, but they're now among the cheapest tariffs so it's worth staying put for the moment.
Very few, if any, suppliers are currently offering fixed tariffs worth swapping to. Fixing a deal does come with a set period of price security - but you'll pay a premium for it.
The price cap on out-of-contract tariffs rose by 54% for a typical user (based on Ofgem's calculation) on 1 April 2022. That means the majority of households in the country are now facing much larger energy bills than they're used to.

Other tips to keep your energy payments in check:
If you're replacing an appliance, you can cut your electricity bills by choosing the most energy-efficient model. For example, depending on size, washing machine running costs can vary from £15 to £70 a year. See our guide to to find out more.
The most obvious indication of a product’s energy efficiency is its EU energy-efficiency rating. But we test energy consumption in a way that reflects how you actually use different appliances, so we can more accurately tell you which ones use less energy.
For example, we test washing machines on the 40°C cottons program most commonly used by Which? members, while the EU Energy Label tests are 60% based on the 60°C cottons program.
Our lab tests reveal the annual running costs for every large appliance. Use the results to find out how much appliances cost to run, and which ones will be the cheapest.
These are the maximum savings based on the difference between the highest and lowest annual running costs from Which? product tests.
Our research shows that swapping power-guzzling kitchen appliances for energy-saving models could save you up to £425 a year.
Got a loft and cavity walls? Insulating both can save you up to £290 a year.
Laying loft insulation to a thickness of 270mm in a typical non-insulated three-bedroom semi could trim £135 a year from energy bills, as less heat will be lost through the roof and insulating cavity walls can save up to £155 a year in a semi-detached house. Solid-wall insulation, although more expensive to fit, could save you £210 in the same type of house.
If you already installed a loft insulation, you could save an extra £100 a year by topping it up from 120mm to the recommended 270mm. And you can also reduce heat loss through your windows by replacing single glazing with .
Your heating is responsible for more than half of your energy bill each year. So replacing an old, inefficient gas boiler with a modern energy-efficient one will make a big difference to your payments.
It could save you £195 per year, if you upgraded an old G-rated gas boiler to a new A-rated condensing one with a programmer, room thermostat and thermostatic radiator valves. That's according to the Energy Saving Trust for a typical semi. If you live in a detached home, you could save £300.
Buying a new boiler can cost a couple of thousand pounds, including installation. So, if money-saving is your top priority and your boiler isn't beyond repair, balance your savings against the cost of the upgrade.
Energy-saving light bulbs can help you to cut your energy bills easily. An LED light bulb costs around £1.71 a year to run. Over its lifetime, it could cut around £180 from your energy bills, compared with an old-style bulb.
Remember, energy-saving light bulbs last longer than traditional ones.
|Type||Lifetime||Annual running cost*|
|Halogen||2,000 hours (around 2 years)||£8.42|
|CFL||10,000 hours (10 years)||£2.04|
|LED||25,000 hours (25 years)||£1.71|
*Annual running costs are based on a typical 700+ lumen bulb, used for around three hours per day for a year.
LEDs are the most energy-efficient light bulbs, and use almost 90% less energy than traditional incandescents. CFL bulbs use 70-80% less energy than traditional bulbs.
Heating controls should let you:
If you only have one thermostat for the whole house, each degree you turn it up will increase your heating bill by around 10%, according to the Energy Saving Trust. So put on a jumper before you turn up the heating.
If you only need to heat one room in your home, it may be cheaper to use a portable electric heater and keep the thermostat turned down. For those who live alone or work from home, investing in an electric heater could save on heating bills over time as you're not heating your whole home unnecessarily.
Electric heaters are best used sparingly though. Electricity is much pricier than gas per hour. Plus our tests found that some heaters don't have very good thermostats so don't give you the room temperature you wanted.
With a smart thermostat you can operate your heating remotely via the internet using your mobile phone, tablet or computer. Some can also learn your routine or adjust your settings depending on the weather forecast.
Coupled with smart thermostatic radiator valves, you can control exactly which rooms are heated, and which aren't.
You can still do this if your thermostatic radiator valves aren't smart - you'll need to turn them off in each room manually.
Whether a smart thermostat could save you money will depend on your lifestyle, how efficiently you control your heating already and whether you’d prefer it to using traditional heating controls. Find out .
Stopping heat from escaping through unwanted gaps around doors and windows could help you save around £25 a year in a typical home, according to the Energy Saving Trust.
You could save even more with professional draught-proofing. Take a look at the following areas:
Though you might only use your heating in winter, you use energy year-round to heat your water. So heating and using it wisely will impact your bills.
Plus, if you have a water meter, these tips will help you save money there too.
If you have a hot water tank (rather than a combi boiler), use your heating controls to turn your water heating on and off, so you only heat as much water as you need.

Energy schemes and grants are available to help pay your energy bills or to support you with the costs of renewable heating. The include:
