Whether you need help switching providers or you just want to cut your energy consumption, it’s worth checking out the advice on offer.  

Big Energy Saving Week is not just about using less energy. It’s also about helping you save money and stay on top of your bills, whether it means accessing financial advice or applying for a boiler grant.

So, if you’re not sure what financial support you’re entitled to, this is the campaign for you. In the meantime, though, here are 10 things you can do to quickly cut your home energy bills. 

1. Turn off standby

Don’t leave devices like TVs, laptops and other computers on standby all night. According to the Energy Saving Trust, you can save up to £90 a year just by switching off appliances at the wall! 

2. Change light bulbs

We’re all home more often right now, which means the lights are on all day. The good news? LED bulbs use 90% less energy than traditional bulbs, so make quick energy savings by making the change.  

3. Do less laundry

In other words, don’t wash small loads. Wait until you’ve got a full load so you’re running fewer wash cycles. 

Do you need to tumble dry everything? Consider air-drying smaller items to conserve energy and save money. 

4. Draught-proof your home

You can save up to £30 a year just by draught-proofing doors and windows, according to the Energy Saving Trust. Just buy some cheap and cheerful draught-proofing strips and secure them around door and window frames. 

5. Switch energy providers

When was the last time you changed energy providers or even checked which tariff you’re on?

  • Check you’re on the cheapest energy tariff by shopping around.
  • Consider switching providers once a year to make sure you get the best deal available. 

6. Check for energy discounts

This is what Big Energy Saving Week is all about – promoting discounts! Here are just some of the discounts and grants you might be entitled to:

  • The Warm Home Discount is available everywhere except Northern Ireland.
  • If you’re in England, check out the Green Homes Grant.
  • In Wales? Give Nest a call on 0808 808 2244 to learn about home energy packages. 

Contact Citizens Advice to find out more about what’s on offer. 

7. Get a smart meter

Check if your supplier offers smart meters. These little devices show you which appliances use the most energy (such as your kettle) so you can take steps to cut costs.

Can’t get a smart meter? Just try to limit how many times you do things like boil the kettle or use a hairdryer. Even small changes add up over time. 

8. Upgrade your appliances

Got old white goods like freezers and washing machines? Chances are, they’re not the most energy-efficient models out there.

Make energy savings by upgrading your kitchen appliances for newer options. 

9. Insulate your home

If you can afford it, invest in some home insulation. While you’re paying more upfront, here’s what you could save each year:

  • Loft insulation: up to £180
  • Wall insulation: up to £140

10. Install a new boiler 

This is the most expensive option, but it’s worth knowing about.

According to the Energy Saving Trust, you can save over £300 a year by switching an old gas boiler for a modern condenser model. These savings really add up over time, although you’ll need at least £1,000 to buy the boiler and pay for installation.

Remember to check whether you’re eligible for a boiler grant before you switch.  


We could all do with saving money right now, and Big Energy Saving Week is a great time to shop around for better energy deals and discounts. We typically use more energy in the winter months, so take action now before the bills start adding up!

Just remember, though, that energy saving advice is available year-round. If you’re worried about paying your bills, or you need help accessing financial support, contact Citizens Advice or the Energy Saving Trust at any time. 

Is this little-known company the next ‘Monster’ IPO?

Right now, this ‘screaming BUY’ stock is trading at a steep discount from its IPO price, but it looks like the sky is the limit in the years ahead.

Because this North American company is the clear leader in its field which is estimated to be worth US$261 BILLION by 2025.

The Motley Fool UK analyst team has just published a comprehensive report that shows you exactly why we believe it has so much upside potential.

But I warn you, you’ll need to act quickly, given how fast this ‘Monster IPO’ is already moving.
