Just as the post-Christmas pinch hits and the weather is doing its worst, Big Energy Saving Week arrives with a simple message: small, practical actions can meaningfully reduce bills, improve comfort at home, and help people access support they might not even realise they’re eligible for.
It’s not about perfection, or turning your life into a spreadsheet. It’s about being a bit smarter with energy at the point in the year when it matters most.
Big Energy Saving Week is a United Kingdom awareness campaign designed to help households take immediate, realistic steps to cut energy costs.
Historically, it has been associated with guidance around checking you’re on the best deal, understanding your energy use, and finding help to make your home more efficient.
Citizens Advice has previously led and promoted the campaign, focusing on helping consumers reduce bills through better deals and practical changes at home.
This year, Big Energy Saving Week runs from 17 January 2026 to 23 January 2026.
Placing it in January is no accident: it’s typically one of the coldest parts of the year, when heating use rises and households feel the cost most sharply.
Energy saving can feel like a private challenge, something you quietly battle in your own home.
But this week is also about visibility, because many people who could benefit from support schemes, switching advice, or basic efficiency improvements simply don’t know where to start.
Campaigns like this encourage conversations, and those conversations can help someone else avoid getting into arrears, reduce stress, and stay warm safely.
There’s also a wider point: using less energy where you reasonably can reduces demand and emissions, and helps the UK move towards a more efficient, resilient energy system. You don’t need to be an eco-expert to play a part. You just need to share what’s useful.
A helpful way to approach the week is the “check, switch, save” rhythm that’s often used across UK energy advice campaigns.
“Check” means looking at what support you might be eligible for and understanding what you currently pay. “Switch” means seeing whether a different tariff or supplier could be better for you. “Save” means reducing wasted energy without making your home uncomfortable.
If you do nothing else, treat Big Energy Saving Week as an organised prompt to review your situation calmly, rather than only reacting when a bill lands.
The best prep is surprisingly boring, but it’s what makes everything else easier. Find your latest bill (or open your app), check what tariff you’re on, and note your payment method.
If you have a smart meter, it’s worth making sure it’s working properly and that you understand what the in-home display is telling you. If you don’t have a smart meter, take a meter reading anyway. It gives you a baseline and helps you spot unusual spikes later.
It’s also worth checking whether you’ve got drafty problem areas you’ve been ignoring because they feel “small”. Gaps around doors, letterboxes, loft hatches and older windows can quietly drain heat.
The week is a good excuse to tackle one or two of these, rather than feeling like you have to overhaul the whole house.
The best energy-saving actions are the ones you’ll actually keep doing in February.
That usually means changes that don’t make your home feel miserable: being more intentional with heating timings, keeping internal doors closed to retain warmth in the rooms you use most, and reducing needless heat loss through draught-proofing.
Energy Saving Trust regularly emphasises that everyday habit changes can cut energy use without demanding big home upgrades.
Think of it as stopping waste, not “using less comfort”. When people frame it that way, the changes are far more likely to stick.
Big Energy Saving Week is also about making sure people get the help they’re entitled to. One well-known scheme is the Warm Home Discount, which is a one-off £150 discount on electricity bills for eligible households, applied through suppliers during the scheme window.
Another under-shared option is the Priority Services Register (PSR), which offers free extra support for people in vulnerable situations (for example, older people, disabled people, or households with young children), including tailored help during supply interruptions. People can usually join by contacting their energy supplier.
Even if you personally don’t qualify, sharing awareness of these two can be one of the most valuable things you do all week.
The simplest way to spread the message is to share one helpful action and one trusted resource, rather than a long checklist.
For example: “Big Energy Saving Week is 17–23 Jan. If you’re worried about bills, it’s worth checking support like the Warm Home Discount or joining the Priority Services Register.” Then point people towards Citizens Advice-style support and reputable guidance.
If you run a workplace, community group, or social media page, you can turn the week into something practical: a daily “one-minute tip”, a short post encouraging people to check their tariff, or a reminder that support exists and it’s normal to ask for it.
The goal isn’t to lecture people. It’s to reduce friction so someone who’s overwhelmed can take one small step.
The week ends on 23 January, but the best outcome is momentum. If you’ve checked your tariff, tightened up one drafty spot, and shared support info with a couple of people, you’ve already made Big Energy Saving Week worth it.
The win is not doing everything. The win is doing something that lasts.

As temperatures dip and energy bills bite, many households are looking for simple, reliable ways to stay warm without overspending. The good news is that a mix of smart heating habits, small changes to electricity use, and a few cost-savvy home tweaks can make a meaningful difference.
Here’s a clear, practical guide to help you keep comfortable and keep costs under control this season.
The most effective way to cut costs is to heat your home only when you need to. Set your heating to come on and off at specific times that match your routine – mornings and early evenings for most homes – rather than leaving it running on high all day.
When everyone is asleep or out, either turn the heating off or set it to a lower temperature. This avoids wasting energy when it’s not delivering any comfort.
Avoid the temptation to put the boiler on full blast. Cranking the heating to maximum doesn’t warm rooms faster; it simply uses a lot more gas and costs more over time. A steady, moderate temperature is both more comfortable and more economical.
If your radiators have thermostatic valves (TRVs), use them to turn down or turn off radiators in rooms you use less. Kitchens and bathrooms often benefit from less heating because they’re used in short bursts and can gain incidental warmth from cooking or hot showers.
Likewise, keep radiators low in rooms that sit empty for most of the day. Zoning your heating like this keeps living areas cosy while cutting waste elsewhere.
Tip: Keep doors closed between heated and unheated spaces to stop warmth drifting away. It’s a small habit with a big effect.
Stopping heat escaping is as important as producing it.
These tweaks are inexpensive and often pay for themselves quickly.
Electricity prices add up fast, but small daily habits deliver quick wins.
Turn lights off when you leave a room, and make it a house rule to switch everything off when you go out. If a bulb needs replacing, choose LED – they use a fraction of the electricity of old-style bulbs and last far longer, saving on both energy and replacements.
Be wary of plug-in electric heaters. They’re simple to use but typically expensive to run compared with gas central heating. If you must use one, keep it for short, targeted bursts in a single small room, and turn it off as soon as you’re comfortable.
Electronics sipping power in standby can quietly nudge your bill upwards. Turn off appliances and computers when they’re not being used, ideally at the socket or via a smart power strip.
Laptops left charging overnight, consoles sitting in “rest” modes, and always-on screensavers all add unnecessary costs over a month.
Consider setting devices to power-save modes and scheduling automatic sleep for computers after brief periods of inactivity. It’s invisible day to day, but it’s valuable on the bill.
You can shrink electricity use further with a few kitchen and laundry habits:
In cooler months, it’s easy to seal the house up tight, but good ventilation matters.
Brief, sharp bursts of fresh air (e.g., five to ten minutes with windows ajar) help reduce condensation and damp – problems that make homes feel colder and can damage walls and clothes.
Use extractor fans when cooking or showering, and keep lids on pans to limit moisture.
Match your heating schedule to when you’re actually home. A short pre-wake cycle can take the chill off mornings, while a late-afternoon boost prepares the home for evenings.
If your thermostat is smart or programmable, use features like setback temperatures and geofencing so the system responds to your comings and goings automatically. Even without smart tech, a simple 7-day timer is an unsung hero for comfort and cost control.
Staying warm this winter doesn’t require a high thermostat or high bills.
Focus on timed, moderate heating, room-by-room control, and switching off what you don’t use. Pair those with quick home fixes – curtains, draught proofing, and simple ventilation – and you’ll feel the difference in comfort and in your energy costs.
Small, consistent habits are the secret to a cosier home and a calmer bill.

As the days grow shorter and the temperatures begin to fall, energy bills inevitably start to climb.
For students living in shared accommodation, this can quickly become one of the biggest financial concerns of the winter months. With several people under one roof, each with their own habits and routines, managing household energy use can be tricky.
But with some small, smart adjustments and a bit of teamwork, students can keep costs under control while staying warm and comfortable.
One of the most effective first steps is to work together as a household. In student homes, it’s all too common for individuals to take different approaches to heating, lighting and appliances, which leads to wasted energy and higher bills.
A simple conversation with housemates about agreeing on shared habits can make a real difference.
Setting the thermostat to the same temperature, switching off appliances rather than leaving them on standby, and keeping communal lights off when no one’s around may sound obvious, but when everyone commits, the savings begin to add up.
It also helps to prevent those awkward end-of-term disputes over who’s responsible for a hefty utility bill.
When it comes to heating, a common mistake is to focus on warming the whole house instead of keeping people comfortable.
Central heating is useful, but it doesn’t always need to be running. Students can save money by heating themselves directly with warm clothes, blankets and hot water bottles, which cost a fraction of the price of hours of radiator use.
Electric blankets and heated throws are also a surprisingly economical option, especially for evenings spent studying at a desk or relaxing on the sofa. They use far less electricity than a gas boiler running for several hours and create a cosy space without heating empty rooms.
The thermostat itself is another key tool that students often overlook. Learning how to use it effectively can cut bills without sacrificing comfort. Turning the temperature down by just one degree may not feel like much, but across a year it can reduce heating costs by around 10 per cent.
Making use of timers is equally important. Setting the heating to come on half an hour before getting up in the morning or arriving home in the evening means the house feels warm when needed, without wasting energy when everyone is out at lectures, work or the library.
Heat can also be easily lost if the house isn’t well insulated. Many student houses are draughty, but there are cheap and effective ways to stop warmth escaping. Draught excluders at the bottom of doors, thick curtains over windows and even rolled-up towels to block gaps can all help.
Opening curtains in the morning allows sunlight to naturally warm rooms, while closing them in the evening helps to lock in heat. For properties where landlords allow minor changes, removable adhesive seals for windows are inexpensive, easy to install, and an excellent way to keep the cold out once winter sets in.
Appliances are another area where small changes go a long way.
Washing machines should be used only when full, ideally on a 30-degree cycle to cut down on unnecessary energy use. Kettles should be filled with only the amount of water needed, not to the brim for a single cup of tea.
Fridges and freezers run more efficiently when full, so even filling empty space with bottles of water can help them work better. Cooking is another big opportunity to save. Instead of each person preparing their own meals separately, students can cook together a few nights a week.
Sharing meals not only saves on energy but also reduces food costs and adds a social element to the daily routine.
Lighting may not be as costly as heating, but during the darker months it still contributes to bills. Replacing old bulbs with energy-efficient LEDs is one of the easiest ways to reduce costs, as they use far less power and last longer.
Encouraging everyone in the house to switch off lights when leaving a room may seem simple, but it’s a habit that can make a noticeable difference over the course of the year. Some households even make it a light-hearted challenge, turning forgetfulness into a small penalty, such as making the next round of drinks.
Students should also remember that it pays to shop around. Energy suppliers often provide different tariffs, and comparison websites can help households switch to a cheaper deal.
Beyond suppliers, there are also student discounts available for energy-saving products such as heated blankets, energy-efficient appliances and homeware. Taking advantage of these offers makes it easier to create a warmer, more efficient household without spending more upfront.
Ultimately, cutting energy use is a win-win for everyone involved. For tenants, it means lower bills, a cosier living environment and fewer disputes about costs. For landlords, tenants who take care of energy efficiency are often easier to manage and cause less wear and tear on the property.
And for the planet, reducing unnecessary energy use contributes to lowering overall carbon emissions.
For students, the key is to see energy-saving not as a restriction, but as a way of working smarter together. With a bit of cooperation and a few clever hacks, it’s possible to keep bills under control without giving up comfort.
So, as the nights draw in, make a hot drink, wrap up in a blanket, and put these ideas into practice. Your wallet – and your future self – will thank you.
