Start With the Things You Never Think About

Most of us have a rough idea of what pushes our bills up: the heating, the hot water, the tumble dryer. What catches people out is the quiet background drain — the appliances and habits that cost a few pounds a week each and add up to a frightening annual total. Before you consider anything expensive, it is worth spending an afternoon dealing with the easy wins. They are free, they take minutes, and in a typical home they can shave a noticeable slice off a quarterly bill.

Standby power is the classic example. Televisions, games consoles, set-top boxes, printers, broadband routers and phone chargers all draw electricity when they are not really doing anything. Individually it is pennies. Across a household it can be £50 to £80 a year. Put the entertainment equipment on one switched extension lead and turn it off at the wall last thing at night. If you have a smart meter, watch the display as you do it — seeing the numbers drop is oddly motivating.

Heating: Small Adjustments, Real Savings

Heating and hot water usually account for well over half of a household energy bill, so this is where attention pays best. You do not need a new boiler to make progress.

• Turn the thermostat down by one degree. Most homes are comfortable at 18–21°C. Dropping it by a single degree typically cuts heating costs by around 10 per cent, and most people genuinely cannot feel the difference after a few days.
• Set the timer around your actual routine. If nobody is home between nine and five, there is no sense heating an empty house. Programme it to come on half an hour before you get up and switch off half an hour before you go to bed.
• Bleed your radiators. If radiators are warm at the bottom and cold at the top, there is trapped air inside and you are paying to heat a pocket of nothing. A radiator key costs a couple of pounds and the job takes ten minutes.
• Move the sofa. Furniture pressed against a radiator soaks up heat that should be warming the room.
• Close curtains at dusk. They act as an extra layer of insulation. Open them again in the morning to let the sun do some free work.

If you have a hot water cylinder, check the thermostat is set to around 60°C — hot enough to keep water safe, but not so hot that you are paying to heat water you then cool down with cold in the tap. A well-fitted cylinder jacket costs very little and pays for itself within months.

Hot Water and Washing Habits

Heating water is expensive, and a surprising amount of it goes straight down the drain. Showers are generally cheaper than baths, but a long power shower can easily use more water than a bath, so keep them to around four minutes. A water-saving shower head mixes in air and gives a decent flow for less hot water — a small change most people stop noticing within a week.

Washing machines and dishwashers are worth a rethink too. Washing at 30°C rather than 40°C or 60°C uses meaningfully less electricity, and modern detergents are formulated to work perfectly well at lower temperatures. Wait until you have a full load, and use the eco setting when you can — it runs longer but at lower temperatures, which usually means lower energy overall. If you have a tumble dryer, it is one of the most expensive appliances in the home. Drying on an airer, a washing line, or over a radiator (with the window open briefly to avoid damp) saves real money. If you must use the dryer, spin the laundry first — the faster the spin, the less water left for the dryer to remove.

Lighting, Cooking and the Kitchen

Lighting is a straightforward one. If you still have any old-style incandescent or halogen bulbs, replacing them with LED equivalents cuts the energy used for lighting by roughly 80 per cent. LEDs cost a little more upfront but last for years. And get into the habit of switching off lights in rooms nobody is using — the old argument about it costing more to restart a light than leave it on does not apply to modern bulbs.

In the kitchen, match the pan to the ring and put a lid on it. A lid traps heat and can cut cooking energy noticeably. Use a kettle to boil only the water you need rather than filling it to the top, and if you are boiling vegetables, an electric steamer or a microwave often uses less energy than a hob. Keep the fridge and freezer at the right temperature (around 5°C and -18°C), away from the oven and radiators, and defrost the freezer if ice is building up — a thick layer of ice makes it work harder for the same result.

Draughts, Damp and Cheap Insulation

You do not need a builder to reduce heat loss. Draught-proofing is one of the cheapest, most effective things you can do, and it makes a home feel warmer even at a lower thermostat setting.

• Block draughts around doors with a brush strip or a simple draught excluder, and use a letterbox flap if yours is missing or broken.
• Seal gaps around windows with self-adhesive foam or silicone, but leave trickle vents open — homes need ventilation to avoid condensation and mould.
• Use a chimney balloon if you have an open fireplace you never use. An open flue is effectively a permanent hole in your insulation.
• Lay a rug on bare floors and use thick curtains, especially in rooms you heat most.

If you are on a low income, check with your local council about grants and schemes for insulation, boiler repairs or heating upgrades — many are undersubscribed simply because people do not know they exist. Your energy supplier may also have a priority services register, and if you are struggling to pay, ask about a repayment plan, a standing charge reduction or the Warm Home Discount. Nobody should be sitting in the cold because they are embarrassed to pick up the phone, and asking early almost always leads to a better outcome than letting arrears build up.

Making It Stick

The trick with all of this is not to attempt everything at once. Pick three changes this week — the switched extension lead, the thermostat down a degree, the four-minute shower — and let them become habit before adding more. Keep an eye on your meter readings so you can see the effect; a small drop each month is proof that the effort is working. Over a year, these unglamorous adjustments often add up to a few hundred pounds, which is money far better off in your pocket than in a utility company's.
