Utility bills are one of the biggest recurring costs for UK households — and with ongoing fluctuations in energy prices, broadband fees and water charges, it's more important than ever to cut back where possible.
Fortunately, there are practical ways to reduce your utility bills without sacrificing comfort or quality of life. Whether you're a homeowner, renter, student or large family, this guide outlines the most effective ways to lower your household bills, make smarter supplier choices, and unlock savings you can bank every month.

What Are Utility Bills?
In the UK, “utility bills” typically include:
Electricity
Gas
Water
Broadband and phone
TV licence
These are essential services — but that doesn’t mean you have to overpay for them. With a combination of supplier comparisons, efficiency improvements and behaviour tweaks, you can drastically cut your monthly outgoings.

1. How to Save on Your Gas and Electricity Bills
a) Compare Energy Tariffs and Switch Suppliers

Use comparison sites like:
MoneySuperMarket
Uswitch
Compare the Market
And check cashback platforms for switching bonuses.

b) Use the Energy Saving Trust’s Tools
The Energy Saving Trust provides UK-specific calculators and advice on reducing energy use through insulation, appliance use and renewable options.
c) Install a Smart Thermostat
Smart thermostats like Hive or Nest can help optimise your heating schedule based on when you're home — saving energy without compromising warmth.
d) Lower Your Thermostat
Reducing your thermostat by just 1°C can save around £100 per year on your heating bill, according to the Energy Saving Trust.
e) Use Energy-Efficient Appliances
When replacing white goods or electronics, look for A-rated appliances. Also unplug devices or use standby-saving plugs to cut phantom energy use.
f) Switch to LED Bulbs
LEDs use 80–90% less electricity than traditional bulbs and last longer.
g) Take Advantage of Grants and Support

2. How to Save on Your Water Bill
a) Check if You’d Pay Less With a Water Meter
If you have fewer people in your home than bedrooms, you might save money by switching to a water meter. Use the Water Meter Calculator from the Consumer Council for Water to check.
b) Reduce Water Usage
Simple actions can cut both water and energy costs:
Fit aerated shower heads
Only run dishwashers/washing machines when full
Turn taps off while brushing teeth
Use a water butt for garden use
c) Request Free Water-Saving Gadgets
Many water companies offer free devices like shower timers and tap inserts — check your supplier’s website.
d) Report Leaks Promptly
Small leaks can cost a fortune over time. Fix dripping taps and running toilets quickly.
3. How to Reduce Broadband and Phone Costs
a) Switch Deals When Your Contract Ends
Many UK households overpay by staying on out-of-contract tariffs. Switch once your contract ends to avoid “loyalty penalties.”
Use comparison sites like:
Broadband Genie
Uswitch

c) Haggle With Your Current Provider
Don't be afraid to call and negotiate a better deal. Let them know you've found cheaper rates elsewhere.
d) Check for Social Tariffs
If you’re on Universal Credit or other benefits, you may be eligible for social broadband tariffs starting at just £15/month. Check with providers like:
BT Home Essentials
Virgin Media Essential Broadband
Sky Broadband Basics
4. How to Cut TV Licence and Streaming Costs
a) Do You Even Need a TV Licence?
You only need a licence if you:
Watch or record live TV
Use BBC iPlayer
If you only use streaming services like Netflix, Disney+, Prime Video or YouTube, you might not need one. Always double-check at https://www.tvlicensing.co.uk.
b) Rotate Streaming Subscriptions
Instead of subscribing to multiple platforms at once, rotate them month by month. Watch what you want, then cancel and move on.
c) Use Free Alternatives
Explore free UK platforms like:
All 4
ITVX
BBC Sounds
Freevee
Pluto TV
Tip: Some bank accounts offer bundled streaming deals or cashback on subscriptions.

Pay utility bills with a cashback credit card (and clear in full each month)
Use cashback platforms when switching broadband, energy, or mobile contracts
Open a current account that rewards direct debits (e.g. Santander Edge)
