Energy, water and everyday running costs have all crept up again this year.
None of these seven habits require a big upfront spend — just twenty
minutes and a bit of consistency.
Key numbers right now:
– £1,725 — typical dual-fuel energy bill under Ofgem’s October to
December 2026 price cap, up 4% on the previous quarter
– 18–21°C — the room temperature range Energy Saving Trust suggests is
comfortable for most households
– ~11% — share of a typical home’s electricity use that goes on
lighting alone
The energy price cap does not limit what any household actually pays —
it only limits the rate per unit. Two homes on the same tariff can end
up with very different bills depending on habits, insulation and which
appliances get left running. That is the good news: a meaningful share
of a monthly bill is still within a household’s control, tariff
shopping included.
The seven changes below cover energy, water and the recurring
subscriptions that quietly renew every year. None of them require
replacing a boiler or moving house — they are the ones worth doing
first.
1. CHECK THE TARIFF BEFORE WINTER, NOT AFTER
(Often the biggest single saving)
Ofgem reviews the price cap every three months, and forecasters expect
a further rise in January. Households on a standard variable tariff
are paying the capped rate by default — it is rarely the cheapest
option available. Run an address and usage comparison every few
months, and weigh a fixed deal against the risk that prices fall again
before assuming it is the safer choice.
A fixed tariff protects against further rises but can include exit
fees, and it stops paying off if wholesale prices drop. There is no
single right answer — it depends on how much certainty is worth to a
given household.
2. TURN THE THERMOSTAT DOWN BY ONE DEGREE
(Roughly £90 a year)
Energy Saving Trust puts the saving from dropping the thermostat by a
single degree at around £90 a year for a typical home — often without
anyone noticing the difference. Set a steady temperature between 18°C
and 21°C rather than switching the heating on and off in bursts, which
uses more energy overall as the boiler works harder to catch up.
Households with elderly residents, young children or anyone managing a
chronic illness should keep the room warmer and check guidance before
turning things down.
3. FINISH THE SWITCH TO LED BULBS
(£25+ a year, plus longer bulb life)
Lighting accounts for around a tenth of a typical home’s electricity
use. LED bulbs use up to 90% less energy than old halogen or
incandescent bulbs and last many times longer, so any room still
running the old bulbs is the cheapest room in the house to fix. Add a
dusk sensor to outdoor lights so they only run when it is actually
dark.
4. DRAUGHT-PROOF DOORS, WINDOWS AND THE LETTERBOX
(Cheap to do, felt every winter)
Gaps around external doors, old sash windows and letterboxes let
heated air escape continuously. Self-adhesive foam strips, a keyhole
cover and a letterbox brush cost very little and typically pay for
themselves within weeks. Close curtains as soon as it gets dark, but
keep the fabric clear of radiators so warm air can still circulate
into the room.
5. RUN WASHING MACHINES AND DISHWASHERS FULL, AND COOLER
(Fewer cycles, lower temperature)
A full load every other day uses less energy overall than frequent
half-loads. Washing at 30°C rather than 40°C or 60°C cuts the
electricity a cycle uses substantially, since heating the water is
what drives most of the cost, and modern detergents are built for
cooler washes. Air-drying on a rack instead of using a tumble dryer
avoids one of the most expensive appliances in an average home.
6. SWITCH OFF STANDBY INSTEAD OF LEAVING IT RUNNING
(Small per device, steady over a year)
Games consoles, set-top boxes, chargers and TVs left on standby draw
power around the clock for no benefit. A single extension lead with a
switch makes it easy to cut several devices off at once at the end of
the day. It will not transform a bill on its own, but it is one of the
only savings here that costs nothing at all to start.
7. REVIEW BROADBAND, INSURANCE AND SUBSCRIPTIONS ONCE A YEAR
(Beyond the energy bill)
Broadband and mobile deals, home and car insurance, and streaming
subscriptions often renew onto a higher price automatically once an
introductory period ends. A single afternoon spent comparing renewal
quotes against new-customer deals, and cancelling subscriptions nobody
watches, regularly turns up savings that have nothing to do with gas
or electricity at all. It is also worth checking whether a household
qualifies for support such as the Warm Home Discount before assuming
none is available.
BEFORE MAKING ANY CHANGES
Every figure above is a typical or average saving, not a guarantee —
the actual amount depends on a home’s size, insulation, current tariff
and how a household already lives. Anyone finding it hard to keep up
with bills should contact their supplier directly; suppliers have an
obligation to offer support such as payment plans before things reach
a crisis point.
Anyone finding bills genuinely unmanageable can get free, confidential
guidance from Citizens Advice or StepChange — both can help negotiate
with suppliers and lenders directly.
