Start With Your Heating Controls

Heating usually accounts for the biggest share of a UK household energy bill, so it makes sense to begin there. Before you buy a single gadget, spend ten minutes looking at how your system is actually being run. Plenty of homes are heated as though every room is occupied all day, every day, which is rarely true.

Set your programmer so the heating comes on around 30 minutes before you get up and goes off 30 minutes before bedtime. If the house is empty during the day, a shorter heating period is generally cheaper than leaving the heating ticking over, provided your home is reasonably insulated. Long gaps let the walls and furniture go cold, so the next warm-up costs more — that is the balance to strike.

Next, look at the flow temperature on your boiler. Most modern condensing boilers run most efficiently at around 55°C to 60°C rather than the 70°C to 80°C many are set to. The radiators will feel less fiercely hot, but the house still reaches temperature and less gas is used getting there.

Fit thermostatic radiator valves if you do not have them, and use them properly. Bedrooms can sit at 2 or 3, spare rooms at the frost setting, and the rooms you actually use can stay higher. Bleed your radiators once a year too — if the top of a radiator is cold while the bottom is warm, trapped air is doing you no favours.

Insulate the Hot Water Cylinder and Pipes

If you have a hot water cylinder, check what is wrapped around it. Many older cylinders have a thin, loose jacket that does very little. A well-fitted cylinder jacket of around 80mm can cut standing heat loss dramatically, and it usually pays for itself within a year or two.

Do not stop at the cylinder. Lagging the first metre of hot pipe running from the cylinder, plus any exposed pipework in a loft, garage or under-floor void, keeps heat where you want it. In winter, a bare copper pipe in a cold loft is also a burst-pipe risk, so lagging is doing double duty.

While you are up there, look at your loft insulation. The recommended depth in the UK is around 270mm, and plenty of homes have far less. Adding a top-up layer is one of the simplest, least disruptive improvements you can make, and it keeps working every single day of the heating season.

Draught-Proof the Doors You Never Think About

Draughts are cheap to fix and surprisingly costly to ignore. Start with the doors you use most — front and back — and work through the details people overlook:

• Brush or rubber seals around the door frame and a draught excluder at the base.
• A letterbox flap with a brush seal, and a cover for the keyhole.
• Sealant or foam strips around ill-fitting patio and French doors.
• Floorboard gaps, skirting boards and the gap where pipes pass through walls.
• A chimney balloon or draught excluder if you have an open fireplace you never use.

One important caveat: do not seal a room that contains a gas boiler, an open fire or a solid fuel stove. These need a permanent air supply to operate safely, and blocking ventilation can create a serious risk. Kitchens and bathrooms also need some airflow to prevent damp and mould, so draught-proof the living spaces and leave the wet rooms breathing.

Small Habits, Real Savings

A great deal of energy is used by routine rather than necessity, and small adjustments add up faster than people expect.

• Keep showers short. A four-minute shower uses far less hot water than a bath, and an efficient shower head can cut it further without feeling like a sacrifice.
• Wash clothes at 30°C and wait for a full load. Modern detergents work perfectly well at lower temperatures.
• Dry washing outside or on an airer when you can — a tumble dryer is one of the most expensive appliances in the home.
• Keep radiators clear. Sofas pushed against them and curtains draped over them trap heat that should be warming the room.
• Open curtains and blinds during the day to let the sun in, then close them at dusk to hold the warmth back.

Appliances and Lighting

The background hum of a home is worth a look too. Lighting is an easy win: LED bulbs use around 90 per cent less energy than the old incandescent ones and last for years, so replace them as they fail rather than all at once.

Standby power is small per device but real across a household. Putting the television, games console and charging cables on a switched extension lead and flicking it off at night takes seconds. When it comes to the kitchen, only boil the water you need, descale the kettle, keep the fridge at around 4°C and the freezer at -18°C, and let leftovers cool before they go in. Use the eco setting on the dishwasher, skip the pre-rinse, and lean on the microwave or air fryer for small portions rather than heating a whole oven.

Making It a Habit

None of these changes requires discomfort. A house at 19°C with the heating on a sensible schedule feels warmer than a house at 21°C with cold draughts and a system fighting to catch up. The trick is to treat it as a routine rather than a project: take a meter reading on the same day each week, glance at your in-home display, and see which changes actually move the numbers in your home.

If money is tight, it is also worth asking your energy supplier or local council about support schemes for insulation and heating upgrades, and checking whether you qualify for any winter discounts. Combine a handful of these measures and the saving is rarely dramatic in any single week — but across a full winter, it is the kind of money you notice.
