Households could save up to £65 before Christmas by adjusting a single boiler setting, Octopus Energy have said.
The energy supplier issued guidance encouraging customers to lower their boiler’s flow temperature, which determines how hot the water is when it leaves the boiler.
Octopus Energy said many boilers are set far higher than necessary by default.
"Your boiler's flow setting controls the water temperature when it leaves your boiler. Its default setting is usually too high."
They said reducing the setting should not make homes feel colder, and the change could cut annual energy bills by up to 12 per cent.
The company said the change could offer welcome savings at a time when many households are facing high costs.
The advice applies to millions of homes that use combi boilers or boilers connected to hot water cylinders.
For households with combi boilers, Octopus Energy recommends setting the flow temperature to 50C for heating and 55C for hot water.

The company said this configuration delivers the highest efficiency for these systems.
Homes with boilers linked to hot water cylinders require different settings.
Octopus Energy said: "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 one third of the way up the tank)".
Octopus Energy said the change is simple, quick and does not require specialist tools or professional assistance.
