Here are some tips on how you could start making your home more energy efficient straight away without spending much – or anything at all.
As well as these small-scale energy saving ideas, there are also bigger home improvement projects you could think about.
The first step to saving money on energy is to understand what you’re spending. That's why a smart meter could help if you were able to get one, because it tells you how much gas and electricity you’re using in real time.
Even without that, you can check your bills and compare your usage to the expected usage for similar households.
Once you’ve worked out how much energy you’re using – and how much it’s costing you – there are plenty of quick wins that might help you reduce it. For example, you could use:
timers for electrical devices
dimmer switches for lighting
low-energy light bulbs
The Energy Saving Trust has guidance on thermostats and heating controls.
Other simple steps could help, such as not leaving gadgets on standby and using draught excluders to keep your home warm.
Sometimes, you might be able to make savings just by making better choices in the home, for example:
Shower or bath?
The Energy Saving Trust says a family of 4 could save about £75 a year on their gas bill if they fitted a water efficient shower head. And if they all swapped a bath once a week for a 5-minute shower, it could save up to a further £20 a year.
High or low temperature washing?
Avoid putting your washing machine onto a higher setting. Most detergents work perfectly well at lower temperatures like 30 degrees. You could save money by using an eco-wash setting and also waiting until you have a full load of washing.
And try to dry clothes on a line, or rack, rather than using a tumble dryer where possible.
Laptop or desktop computer?
If you have a desktop computer, try to avoid using it if you can use a laptop instead. Laptops typically use a lot less power, according to the Energy Saving Trust, so this could make a big energy saving if you're working from home, as has become the norm for many people.
A laptop can also give you the freedom to work wherever you want in your home, so there's no need to feel tempted to turn up the heating if you're in a cold room.
According to research by the consumer group Which?, switching energy supplier is one of the most straightforward ways many of us could save money.
It says 11 million households are on a standard or default tariff but could save around £330 in a year by switching to the cheapest available deal.
You can get advice on how to do this from Ofgem (the Office of Gas and Electricity Markets). It has a list of accredited price comparison websites as well as tips on how to shop around.
Citizens Advice also has a guide to switching energy supplier, which includes guidance on what to do if you’re a tenant or in debt.
And MoneySavingExpert has launched an autoswitch service, which means you can choose to switch automatically every year to the cheapest deal.
If you’re struggling with heating costs, you might qualify for government support.
The Warm Home Discount Scheme means you could get a discount of £140 on your electricity bill between September 2020 and March 2021 if you receive Pension Credit or are on a low income. It might apply to your gas bill instead if you get gas and electricity from the same supplier.

For some bigger projects, you may need to invest a decent amount of money.
But if you're a homeowner or a landlord in England, you could get up to £5,000 towards the cost of improvements that make your home more energy efficient.
This would be through the government's Green Homes Grant scheme. It covers things like insulation, low-carbon heating, draught proofing and double glazing.
If you qualify, you could get a voucher covering two thirds of the cost of home improvements up to a maximum of £5,000.

If you’re still not sure where you might be able to save money on energy, the government-backed Simple Energy Advice website has a useful energy efficiency calculator you can use.
