Octopus Energy has suggested some money saving measures which Britons could adopt in order to slash energy bills by hundreds.

While many people have been doing everything they can to cut costs during the cost of living crisis, it may be there are some relatively lesser-known suggestions.

Octopus Energy explained their top tips have been compiled with the help of scientists, engineers and heat specialists.

The energy supplier said hundreds of thousands of customers who tried all of their tips out have said they were useful.

Change the boiler’s flow temperature

Turning down a boiler’s flow temperature and setting it between 55 and 60 degrees could potentially save a person up to £87, according to Nesta.

The boiler’s flow setting controls the temperature of the water when it leaves the boiler, and according to experts at Octopus Energy, the default setting is usually too high.

The energy supplier recommended people with a combi boiler set the flow temperature to 50 degrees Celsius for heating and 55 degrees Celsius for hot water.

“If you have a boiler and a hot water cylinder, we recommend setting the flow temperature on your boiler to a few degrees over 60c for heating and hot water, and setting your hot water cylinder to 60c (you’ll usually find the control for your cylinder ⅓ of the way up the tank),” they added.

Don’t tumble dry

Opting for air drying rather than putting wet clothes in the tumble dryer could save £62 a year, according to the Energy Savings Trust.

Octopus Energy also warned against drying clothes on radiators.

“This makes your boiler work harder,” the energy experts said.

Fill in the gaps

Finding and filling up draughts around doors, windows and other gaps to keep the warmth in could see people save £97 on their bills.

While professional draught-proofing can cost several hundred pounds, people could find draughts themselves using the back of their hand or a thermal camera, then make DIY draught excluders using old scraps of fabric.

Control the thermostat

Tweaking the thermostat, such as using it as an on/off switch or boost button, can mean more gas is wasted, according to Octopus Energy.

The supplier says controlling the thermostat by setting it and leaving it on for while the heating is needed, could save almost £100.

The energy experts said: “Setting your thermostat to somewhere between 18-21°c is ideal, and turning down the temperature by just one degree could save up to £99 on your energy bill.”
