Every guide on Cash Saving Expert is a fix: a specific thing you can do to spend less. Each one carries a Fix Rating, so you can see before you start what it will cost you in time and effort, and roughly what it could be worth.
Why we sort by time
Most money advice is organised by topic: energy, banking, insurance. That is useful when you already know what you want to fix. But most people’s real constraint is not knowledge, it is time. You have twenty minutes on a lunch break, or an evening, or a Saturday morning.
So we let you start from the time you have got. Pick Got 30 minutes? and you will see only the fixes you can finish in that window.
The four parts of a Fix Rating
Time
Roughly how long the fix takes a typical person doing it for the first time, including finding paperwork and making the call. For ongoing habits, it is the time to set the habit up. These are honest estimates, not best-case figures: a phone call to a retentions team includes the time on hold.
- Under 30 minutes — one call, one form, one switch.
- An hour or two — worth clearing an evening for.
- Half a day or more — a proper weekend project.
- Ongoing habit — a small change you repeat.
Effort
- Easy — no specialist knowledge, nothing to go wrong.
- Some effort — paperwork, comparing options, or a firm conversation.
- Involved — several steps, tradespeople, or decisions with real consequences.
Saving potential
Shown as £, ££ or £££. This is a deliberately rough, relative band for a typical UK household:
- £ Small but easy — worth doing because it costs so little effort.
- ££ Worthwhile — a meaningful sum over a year.
- £££ Big potential — among the largest savings available to most households.
We do not print a single pound figure, because we cannot know your bills, your usage or your circumstances. A saving that is £££ for one household can be nothing for another. The band tells you where to look first; your own numbers tell you what it is worth.
One-off or habit
A one-off fix is done once and keeps paying: switching a tariff, challenging a council tax band, cancelling a subscription. An ongoing habit only pays while you keep doing it: meal planning, shopping reduced stock, packing a lunch.
How we write and check guides
- Guides explain how things work, with the steps to act on them. They are general information, not personal financial advice.
- Where rules, allowances or prices change, we tell you where to check the current figure rather than printing one that will go out of date.
- Where a topic touches regulated financial products, we point you to free, impartial help such as MoneyHelper, Citizens Advice and StepChange.
- Ratings are reviewed when a guide is updated. If you think one is wrong, tell us — reader corrections are one of the main ways this site stays accurate.
How we make money
Some links may earn us a commission. That never changes a Fix Rating, and many of the best fixes — challenging a council tax band, cancelling a subscription, cooking in batches — earn us nothing at all. See our affiliate disclosure for the detail.
