I don't follow many people when it comes to money.
Markets are noisy. Finfluencers are… enthusiastic. And most "advice" is either obvious or trying to sell you something.
But Martin Lewis is the exception.
Not because he's exciting — he isn't. Not because he predicts the future — he doesn't. But because, over time, his advice has quietly saved me a lot of money. Not in one big moment. In dozens of small, boring, very real wins.
The car insurance trick that feels borderline illegal
If you've ever just accepted your renewal quote — stop doing that. Seriously.
One of Martin's most-repeated tips: get your car insurance quote 3–4 weeks before your renewal date. Not the day before, not on the day. Weeks before.
I've followed that every year. And every year:
- Renewal quote: £800–£1,000
- Early quote via comparison site: £600–£750
- Same details. Same cover. Less money.
It's not a hack. It's just how insurance pricing models work — they penalise last-minute buyers. But if you don't know it, you overpay. Every time. Over a decade of driving, that's not pocket change.
Comparison sites: boring, effective, underrated
There's always someone saying "just go direct" or "comparison sites are a scam." They're not.
Used properly, they're one of the easiest ways to stop overpaying for insurance, broadband, and energy deals. MoneySavingExpert was built on one core principle: check the market before you pay anything.
I don't obsess over it. I just don't blindly accept the first number I'm given. That alone puts you ahead of most people.
The 0% balance transfer move (quietly elite behaviour)
This one isn't flashy — but it's powerful.
If you're paying interest on credit card debt while 0% balance transfer offers exist, you're essentially opting in to losing money. Martin's stance is simple: if you can legally avoid interest, do it.
You move existing credit card debt to a new card offering 0% interest for an introductory period — often 12–24 months. You pay a small transfer fee (usually 1–3%), but pay zero interest while the deal lasts. The goal: clear the balance before the 0% period ends.
Martin Lewis covers current best offers on MoneySavingExpert's balance transfer page.
I've used 0% cards to move balances, buy time, and pay things down properly. No drama. No stress. No interest. It's not clever — it's just sensible.
The car finance scandal (this is the big one right now)
This is where things get properly relevant.
The UK car finance mis-selling situation — involving lenders like Black Horse — is potentially huge. In short: some car finance deals may have included hidden commissions that increased what you paid without your knowledge. If that applies to you, you might be owed compensation.
Naturally, claims management firms have arrived like seagulls on chips. "You could be owed £X,000!" "No win, no fee!" "We'll handle everything!" What they quietly omit: they'll take 20–30% of your payout.
Martin Lewis has been very clear on this. His full guidance is on MoneySavingExpert's car finance reclaim page — and the core message is: in many cases, you can do this yourself.
The old process, if you wanted to pursue it yourself, was straightforward enough:
- Contact your lender directly
- Submit a complaint
- Escalate to the Financial Ombudsman if needed
Same process. Same potential outcome. But you keep 100%.
But here's the update that makes this even simpler: if you're owed compensation, you may not need to do anything at all. Following FCA intervention in late 2025, insurers are now required to proactively contact affected customers directly. If you're owed money, your insurer should be reaching out to you — not the other way around. The FCA's own guidance is clear: there's nothing you need to do if you're due compensation.
Which makes the claims management firms even harder to justify. You're not just paying for convenience anymore — you're potentially paying a 20–30% cut for something that was already going to land in your inbox.
A word on the Twitter polls (love him for it)
Quick side note: @MartinSLewis on X (formerly Twitter) runs polls that are genuinely fascinating from a behavioural finance perspective.
Good pulse checks on how the UK public actually thinks about money. Massively engaging. And occasionally the answer options are… ambitious. Sometimes it's like:
- "Yes"
- "No"
- "I've never heard of money"
- "I once saw a pound coin in 2007"
I respect the chaos entirely. But despite the occasionally rogue answer sets, the underlying point always lands: most people don't optimise their finances nearly as much as they could. And that's where the opportunity sits.
The bigger pattern most people miss
None of this advice is revolutionary. There's no "get rich quick", no secret loophole, no one weird trick. It's just:
- Don't overpay for insurance
- Compare before you buy
- Avoid unnecessary interest
- Don't outsource simple things to companies that charge for the privilege
That's it. But stacked together, over years? It's genuinely powerful.
Wealth isn't built only by earning more — it's built by leaking less.
Why this matters more right now
The margin for error is smaller than it used to be. Costs are higher, rates have been volatile, and everything feels a bit tighter. Which makes these "small" wins more important — because they're not risky. They're guaranteed.
Saving £300 on insurance is better than chasing £300 in the market and hoping. One is certain. The other isn't.
Where Wealthr fits in
Knowing this stuff is one thing. Actually seeing the impact is another.
That's why I built Wealthr. Not to replace advice like this — but to make it visible. So when you save £250 on insurance, avoid interest on a balance transfer, or reclaim money you were owed, you actually see your net worth improve, your trajectory shift, and your decisions compound over time.
That's when behaviour sticks. Not when you read it — when you see it.
See your money actually move
Track your net worth, watch the impact of every win, and build a picture of where you're genuinely headed — free to use, no bank linking required.

I don't agree with everything Martin Lewis says, and you shouldn't blindly follow anyone in personal finance. But if I look at the decisions that have genuinely made me better off over time — a lot of them trace back to him.
Not flashy. Not exciting. But consistently right. And in personal finance, that's about as good as it gets.
