Saving money when using your heating

Draught-proof your home the easy way

Draught-proofing is an easy way to cut your energy use, by stopping cold air coming in under your door or around your windows. Reducing draughts means that your heating system won’t have to work as hard to reach your desired temperatures, and so will help your energy bills.

An old pillowcase or pair of tights filled with stuffing, and placed in a draughty door or window gaps could be enough to stop that draught, and save you money. You can buy specially made draught excluders – or you can make your own.

Turn down the flow-temperature on your combi-boiler

Radiator-flow temperature is the temperature of the water that your boiler sends through to your radiators. This is different to your hot water temperature. If you have a combi-boiler, you can reduce the flow temperature down to 60 degrees Celsius and save up to 8% on your gas bill.

Follow this easy step-by-step guide to find out how to change the flow-temperature on your combi-boiler

Install foil behind your radiators

If you have a radiator against an external wall, you will be losing heat from one side of the radiator through the wall. By installing a strip of radiator foil behind the radiator, you can reflect heat back into the room, and prevent it being wasted.

Installing radiator foils is easy, whatever your DIY skills. You can buy specially designed sheets from your local hardware store, but if you are on a tight budget, you can even use standard tin foil – although this will not work quite as well. Watch this video walkthrough to install radiator foil and save energy.

Use your radiator’s thermostat to control the heat in different rooms

Most radiators have simple thermostats on them that you can use to control the temperature of individual radiators. This will be a small knob on the side of the radiator with some numbers on it, usually with a scale from 0 to 6, where zero (0) is off and six (6) is fully open. Try aiming for the lowest temperature that keeps the room comfortable in each room. 

You can also use this to control the temperature of different rooms, so you can save energy being wasted in a room which you don’t use, or that you would like to be cooler (such as your bedroom). You can watch this short guide to using your room and radiator thermostats efficiently

Myth-buster: don’t leave your heating on low all day when you are out

This will waste energy when you don’t need it. If you want the house to be warm for when you return home from work, use a timer to set the heating to come on about 30 minutes before you arrive home. You can read more about how to get the most out of your heating controls.

Saving money on travel

Leave your car at home – walk or cycle instead

Cars can be expensive, even after we’ve purchased or leased them. An easy way to save money on fuel and parking costs is to choose to walk or cycle for your local journeys.

Better yet, it will help to keep you fit and healthy.

You can find information to help you cycle in Southwark, such as cycle route maps, cycle skill courses, and guided rides.

Saving money with food and shopping

Microwave more meals

If you have a microwave, try swapping the oven for the microwave occasionally.

A microwave uses significantly less energy than either a gas or electric oven, so you will be saving on your energy bills.

You might be surprised what you can make using the microwave, like this speedy vegetarian chilli recipe.

Stick to your shopping list

Use your shopping list to make sure you buy just what you need and avoid wasting food.

According to Love Food Hate Waste, the average family wastes £720 a year in food it throws away. You can try adopting simple food habits to remove a lot of the stress around food, and save you time and money.

If you are struggling to afford food, you can get help to access food.

Saving money with your household appliances

Switch lights and devices off when you don’t need them on

Devices left in standby mode still use electricity. You can also save energy by switching the lights off every time you leave a room.

The Energy Saving Trust estimates turning off your lights and devices could save you £90 a year.

You can find out which of your home appliances waste the most energy.
