How to save money on your home bills, the complete guide
What's the fastest way to cut my home bills? Start with the free behavioural wins: turn your thermostat down by 1°C (up to about 10% off your heating bill, per the Energy Saving Trust), switch appliances off at the wall instead of standby, swap remaining bulbs for LEDs, wash clothes at 30°C, and fix dripping taps and leaky loos. Then work through each utility in turn using the three guides below, heating & gas, electricity, and water.
In this post, we'll cover
Key takeaways
- The cheapest savings are behavioural, they cost nothing and start working today.
- Heating is usually the biggest slice of an energy bill, so it's where the largest wins live.
- “Phantom” standby power quietly adds to your electricity bill all year round.
- A water meter can cut your water bill if you use less than average for your household size.
- Many water companies give away free water-saving devices via GetWaterFit.
- Well-maintained boilers and appliances run more efficiently, and cost less to run.
There's no single switch that halves your bills, but there are dozens of small ones, and together they add up to real money. The trick is to work through your home methodically rather than trying to do everything at once.
This hub is your map. Below you'll find the quick wins to start with today, then three dedicated guides that go deep on each utility. Pick the bill that's bothering you most and dive in.
Your three utility guides
Each guide is a practical, room-by-room walk through one bill, what drives it up, and exactly what to do about it.
Thermostats, boiler flow temperature, draught-proofing, radiators and insulation, where the biggest energy savings live.
Standby power, LED lighting, laundry habits, appliances and off-peak timing, the everyday electricity drains and how to stop them.
Meters, leaks, showers, free water-saving devices and simple habits, how to use less water without noticing.
Quick wins to start today
Before the deep dives, here are the changes that take minutes and cost little or nothing. Savings figures below are indicative estimates from the Energy Saving Trust for a typical home, your own savings will vary, and the pounds move up and down with energy prices.
- Turn the thermostat down 1°C: up to ~10% off your heating bill.
- Switch off standby: around £65 a year (Energy Saving Trust).
- Swap to LED bulbs: uses far less electricity; long payback in months.
- Wash clothes at 30°C: most of a wash's energy goes on heating water.
- Draught-proof doors & windows: around £125 a year (Energy Saving Trust).
- Only boil the water you need: kettles are surprisingly power-hungry.
- Fix dripping taps & leaky loos: a slow leak wastes water day and night.
- Shorter showers: cuts both your water and your hot-water energy.
Do the free stuff first
The golden rule of saving money on bills: exhaust the behavioural changes before you spend a penny on upgrades. They're immediate, they're free, and they tell you how much you can save before you invest in insulation, a smart thermostat or new appliances.
Three principles behind every saving
Once you've done the quick wins, almost every further saving comes down to one of three ideas, worth keeping in mind as you read the utility guides:
The pattern that ties it all together
- Use less. Behaviour and habits, the cheapest lever, and where you always start.
- Waste less. Draughts, leaks, standby and poor insulation all pour money away silently. Plug the leaks.
- Run it efficiently. A serviced boiler, a well-maintained appliance and the right settings do the same job for less.
Where cover fits in
Saving money on bills and protecting yourself from surprise costs are two sides of the same coin. An efficient home is a well-maintained home, and a boiler that's serviced, radiators that are balanced, and appliances that are looked after all use less energy while they're at it. Cover keeps those things maintained and gets them fixed fast when they fail, so a breakdown never becomes the biggest bill of your year.
Protect your home while you save on it.
A serviced boiler runs more efficiently. A fixed leak stops wasting water. A maintained appliance costs less to run. Smart Cover's home emergency, boiler and appliance cover keeps your home running smoothly, and shields you from the big, unexpected repair bills.
Cover doesn't replace your energy supplier, it protects your home's appliances and systems from breakdown.
