Skyrocketing UK energy bills have played a major role in the ongoing cost of living crisis.

And even though the rate of inflation has gone down in recent months, at around 4% it remains around twice what it should be.

So, it should come as no surprise that more and more people are desperately looking for energy saving tips that work.

Here’s why:

According to Ofgem, the latest rise in the energy price cap from 1 January 2024 means the average energy bill in the UK will increase to £1,928 a year for the typical household paying by Direct Debit, up by £94 from the previous three-month period leading up to 31 December 2023.

So, the burning question remains:

How can I reduce my home power consumption?

At Plumbing Superstore, we’re here to help!

With more and more people struggling to make ends meet and looking for ways to save electricity, we decided to put together a list of tried and tested energy saving tips, so you have a better understanding of how to save energy at home.

Let’s dive in.

How to save energy at home without breaking the bank

There’s a lot you can do when it comes to reducing electricity consumption at home with heating and ventilation. However, some home energy saving tips, such as switching to an air source heat pump, require a considerable initial outlay which could potentially prove beyond many people.

Luckily, that’s not the case across the board.

Here’s the deal:

There are quite a few simple things you can do which require little or no investment on your part. We’re going to start with these straightforward tips to save electricity.

Switch off standby mode

Leaving devices on standby mode is a sin most of us are guilty of committing time and again, simply because we tend not to think about it. And yet, remembering to switch off devices we’re not using at the moment can go a long way towards saving energy at home, whether we’re homeowners or renters.


Standby mode isn’t as big of an issue as it used to be since most devices are far more energy-efficient than their predecessors. That being said, standby mode is still wasted energy, with some studies suggesting that the average UK household wastes a massive 7,374 hours of energy every year as a result of these ‘phantom’ or ‘vampire’ loads.

Depending on the number of devices, you might be able to save anywhere from £40 to over £100 a year by not using standby mode, making this one of the easiest UK energy saving tips to take on board.

Don’t overfill the kettle

Whatever our preferred brew, in the UK we love nothing better than a cuppa. In fact, we make around 100 million cups every single day, which amounts to a whopping 36 billion a year!

The problem is:

When we make a cuppa, many of us automatically fill the kettle all the way to the brim, which is grossly inefficient. And if our thoughts are somewhere else and it’s slipped our minds, almost one-quarter of us re-boil the kettle, which makes matters even worse.

It might take a bit more attentiveness, but you should only boil as much water as you need. By doing so, you’ll be able to save between £20 and £35 a year. Don’t knock it.

Don’t be blinded by the lights

Walking out of a room and leaving the lights on is yet another thing many of us do in a fit of absentmindedness. In fact, the bigger our households, the bigger the problem. And yet the fix is so simple.

Simply switching off lights when you’re not using them could save you around £20 per year. Electric saving tips don’t get any easier than that!

But wait! There’s more:

Ordinary lightbulbs are incredibly inefficient. In contrast, LED lightbulbs use around 70%-80% less energy – which, bearing in mind that lighting can amount to up to 11% of your electricity bill, is quite a lot. That’s why you should consider replacing your old bulbs with LED ones.

Sure, they’re more expensive, but you can save anywhere between £5 and £13 per bulb per year. Besides, LED bulbs last way longer than incandescent ones – between 50,000 and 100,000 hours compared to a mere 1,200 hours.

This is huge! It also means you won’t have to worry about changing your lightbulbs constantly.

Wash & dry clothes smarter

If you plan ahead, you can do one less washing cycle per week. Try to combine similar types of colours, clothes and other items for a fuller load. And unless your washing machine is quite old, feel confident to wash at 30° as much as possible.

The thing is:

Most of us tend to opt for a 40° cycle by default, but modern washers and detergents are perfectly capable of doing a proper job using the lower temperatures. This way, you’ll save around £28 a year.

In terms of how to save on your electric bill, you also need to know when to use the washer. The cheapest time to use the washing machine is between 10pm and 5am, when energy tariffs are lowest.

Then there’s drying. Tumble dryers are incredibly convenient because they take so little time to dry our clothes. Unfortunately, they also use a lot of energy. That’s why you should air dry your clothes as much as possible, especially during the warm, dry months.

Remember – clothes horses and washing lines are your friends, so much so that cutting down your tumble dryer usage over the course of a year could leave you around £60 better off.

Turn down the thermostat

Turning down the thermostat is one of the easiest things to do. It’s also one of the most problematic, especially in a larger household, where different members have different temperature preferences. And yes, the old joke about Dad warning you not to touch the thermostat springs to mind.

That being said:

While not everyone is comfortable with a colder home, there are ways to go about it without freezing, such as putting on a bigger jumper or a snuggie blanket during the day and using a hot water bottle at night. In case you weren’t aware, Public Health England recommends an indoor temperature of 18°-21°.

What’s more:

There are considerable savings to be had. For instance, turning down your thermostat by just one degree can save you around £130 a year. In addition, you shouldn’t heat unoccupied rooms. If no one’s using the bedrooms, why leave the heating on? Keep in mind that to switch it off, you’ll need individual thermostats, preferably smart ones (more on that later).

This might seem like an unnecessary investment, but it’s an investment well worth making. Contrary to popular belief, it’s actually cheaper to have the heating on only when you need it rather than having it on low all day. Just make sure you keep the doors between heated and unheated rooms closed to prevent heat loss.

Hurry up in the shower

Everyone loves a nice, hot shower on a cold winter’s day – or a long, cold shower during a heatwave. But if you cut your shower time to 4 minutes, you might be able to save about £70 per year for the entire household. Don’t forget you’ll also save money on your water bill. Like quite a few of the other home energy efficiency tips on our list, it’s really quite simple, as all it requires is a bit of discipline.

But how do you measure the time, I hear you ask?

One way is to buy a shower timer. But wait – there’s already a device we all own that makes the extra spending unnecessary – the smartphone. Simply put on a favourite song around the four-minute length, and you’re good to go. Just don’t go for Enya or something similar, or you’ll end up spending 40 minutes in the shower – not 4 – and waste rather than save energy!

Another thing you can do to up your shower game is install a more efficient shower head. This has the added benefit of making your showering experience more pleasant.

Bleed the radiators

If you have a central heating system, you have radiators. And that means air can – and often does – get trapped inside them, preventing them from functioning properly.

The question is:

How do you know that’s the case?

One thing to note is that a radiator with air in it will take longer than usual to heat up. Also, you might feel cold spots on it. Luckily, bleeding your radiator is easy and only takes about 10 minutes.

And guess what? By boosting your energy conservation efforts as well as making your home cosier and more comfortable, this simple task can help you save plenty of money on energy bills – over £90 a year, as it turns out!

So, you should bleed your radiators at least once a year, the perfect time being just before you switch on your heating for the winter.

Draught-proof your home

In order to maximise your electricity savings, you need to avoid wasting heat at all times. And one of the best ways to do this is to draught-proof your doors, windows and any unused chimneys to effectively prevent cold air from entering your home and warm air from escaping. If you’re a seasoned DIYer, you can do it yourself.

But if you’re not confident in your abilities, you can always call in the professionals. Keep in mind that this will set you back a couple of hundred pounds.

It’s well worth it, though:

By draught-proofing your doors and windows, you’ll save around £45 a year and as much as £65 if you do the same with your chimney.

So, if you’re wondering ‘how can I save on heating without breaking the bank’, you now have your answer – or at least part of it.

Invest in smart heating controls & appliances

We now get to some of the more expensive energy saving ideas. We recognise that not everyone will be able to set aside the amount of money required to carry them out. But while it’s true they mean a significant initial outlay, the long-term benefits will be significant.

Here’s the scoop:

One of the best things you can do in terms of power saving is to invest in smart heating controls and appliances. A smart thermostat will allow you to control the temperature in your home on the go. There’s no point in having the heating on when there’s nobody in, right? But you don’t want to come to a cold home after a long, hard day of work either.

Smart thermostats offer the best solution and allow you to monitor your energy usage closely. Ideally, you should have one in each room, so you can set a different temperature for each zone. Over time, they learn your habits and adapt, allowing you to use as little energy as possible without compromising on comfort. This enables further customisation of your thermostat options while the heating and hot water systems are in operation.

It gets better:

If you install smart thermostats, programmers and thermostatic radiator valves, you’ll be able to save as much as £75 on your energy bills. Besides, you’ll increase the comfort of your home. A win on all fronts!

But that’s not all:

When it comes to how to save electricity, a smart meter is another must-have. In fact, the government plans for 74.5% of homes and nearly 69% of small businesses to have smart meters by the end of 2025.

So, you should get yours as soon as possible. If you haven’t done so already, get in touch with your energy supplier to set up an appointment. In fact, many of them will replace your old meter with a smart one for free, and they might even sweeten the deal with a free gift!

Last but not least, consider replacing older appliances with smart ones, as they can be a significant drain on energy, especially in a larger household. In contrast, new ones are highly energy efficient.

Install insulation

Did you know that you’re losing one-quarter of your heat if your roof is uninsulated?

This is huge!

So, the best way to conserve energy is to install insulation. Start with your loft, but don’t end there! While you’re at it, insulate the walls and windows.

Then, do the same for your hot water cylinder and any exposed hot water pipes to prevent them from losing heat. This will also ensure that hot water stays hotter for longer, providing a more consistent and efficient hot water supply throughout your home.

Additionally, pipe insulation can prevent freezing, overheating, warping and corrosion from occurring, effectively addressing these issues before they even arise and saving you money on maintenance and repair. For best results, use a British Standard Jacket 80mm thick.

Yes, insulation is expensive, but it’s guaranteed to save you loads of money in the long run. If you have cavity walls, you might be eligible for a government grant, so make sure you check with your local authorities. At the end of the day, you need all the help you can get.

How many kWh does the average home use in the UK?

The amount of energy your household uses is measured in kilowatt-hours (kWh). It might come as a surprise, but today UK homes use around the same amount of energy as they did 30 years ago, even though the typical household has roughly four times as many appliances (13) as it did back in 1990 (4). That’s due to a variety of factors, such as vastly improved energy efficiency.

But with so many appliances, what uses the most electricity in a house?

That would be your wet appliances – washing machines, tumble dryers, dishwashers and so on – which together account for 14% of your typical bill.

So, what are the actual numbers?

Here’s the scoop:

The average annual electricity usage in a small household (1-2 people living in a flat or a 1-bedroom flat) is 1,800 kWh. The corresponding figures for a medium household (2-3 people in a 3-bedroom house) and a large one (4-5 people living in a 5-bedroom house) are 2,900 kWh and 4,300 kWh, respectively.

In addition, the average annual consumption of gas for small, medium and large households is 8,000 kWh, 12,000 kWh and 17,000 kWh, respectively.
