How to save money: practical ways to cut costs in the UK
Quick answer: Save money by tackling your biggest bills first — energy, mortgage or rent, insurance and food — then automating regular savings. Switching providers and reviewing subscriptions often frees up the most cash for the least effort.
Saving money is less about cutting every small treat and more about fixing a few big, recurring costs. This guide focuses on the highest-impact moves first, then the smaller habits that add up over a year.

Start with the big bills
Review your energy tariff, insurance renewals (home, car, life) and any mortgage deal coming to an end. Comparison sites and a quick switch can save hundreds a year, and insurers in particular often quote new customers less than loyal ones.
Check your council tax band and discounts, and your mobile and broadband contracts — many people pay for out-of-contract deals far above the going rate.
Then the everyday habits
Cancel subscriptions you no longer use, plan meals to cut food waste, and use cashback or loyalty schemes you would shop with anyway. Avoid buy-now-pay-later for non-essentials, which can quietly stretch your budget.
Most importantly, automate the saving itself: move a set amount to a separate savings account the day you are paid, so saving happens before spending.
Common questions
What is the quickest way to save money?
Tackle your biggest recurring bills first — switching energy, insurance and broadband, and remortgaging when a deal ends, usually frees up far more than cutting small treats.
How much should I save each month?
A common target is 20% of take-home pay, but any regular amount helps. Start with what you can sustain and increase it as bills come down.
