Gen Z vs Millennials in the UK: Who's Actually Better at Saving in 2026?

Gen Z save more often. Millennials have more saved. Both statements are true, and neither is the interesting bit. In Q2 2026, 42.4% of Gen Z said they were putting away more than usual — the highest of any UK generation for the second quarter running — against 39.9% of millennials, according to Kent Reliance's SaveUp Quarterly Savings Index published on 9 July 2026. But on balances, millennials are comfortably ahead: Finder's January 2026 survey of 2,000 UK adults put average savings at £11,023 for 25-34 year olds and £13,379 for 35-44s, against £2,699 for 18-24s.

The headline "who wins" framing falls apart the moment you look one layer down. Roughly one in five people in both generations has nothing saved at all. That divide — inside each generation — is now wider than the gap between them, and it's the number worth paying attention to if you're trying to work out where you stand.

The condensed version

• Gen Z save more frequently. 42.4% were saving more than usual in Q2 2026, the most savings-active generation for a second consecutive quarter (Kent Reliance, 9 July 2026).
• Millennials hold more money. Average savings of £11,023 for 25-34s and £13,379 for 35-44s, versus £2,699 for 18-24s (Finder, survey January 2026) — largely a function of extra earning years, not better habits.
• Millennials had the better quarter. They were the only generation whose savings activity rose quarter-on-quarter in Q2 2026, up to 39.9%, while Gen Z's net agreement score fell from 18.5% to 9.1% (Kent Reliance, 9 July 2026).
• Both generations are splitting in two. 20% of Gen Z and 17% of millennials have no savings at all (Finder, 2026); Kent Reliance separately found 21.3% of millennials with none. Meanwhile 18.2% of Gen Z have already passed £10,000.
• The April 2027 cash ISA cut hits both and spares neither. The allowance drops to £12,000 for under-65s while over-65s keep £20,000 — which means every Gen Z and millennial saver.

The two questions people are actually asking

"Who's better at saving" collapses two different measurements that point in opposite directions.

Savings activity is what proportion of a generation is putting money away right now. It's a behaviour measure, and it's the one Gen Z lead.

Savings held is the balance sitting in the account. It's an accumulation measure, and it mostly tracks how long you've been earning. A 41-year-old with £13,000 saved and a 22-year-old with £2,700 saved may well be saving at identical rates.

Comparing a 22-year-old's balance to a 41-year-old's and concluding one generation is "worse with money" is a category error. Comparing their rates is fairer — and on that measure the younger group is doing rather well.

Round 1: who's saving more right now

Kent Reliance's SaveUp index tracks how many people in each generation say they're saving more than they usually do. Here's Q2 2026, published 9 July 2026:

Source: Kent Reliance SaveUp Quarterly Savings Index Q2 2026, published 9 July 2026. Across all UK adults, 27.8% were saving more than usual.

Two things stand out. First, Gen Z hold the top spot but their momentum is fading — the net agreement score roughly halved between Q1 and Q2. In Q1, 44% of Gen Z had said they were saving more than usual (Kent Reliance via Money Marketing, 22 April 2026), so the direction of travel is down.

Second, millennials are the only generation moving the other way. Louise Halliwell, Group Savings Director at Kent Reliance, called it a positive story showing "that determined saving can continue even when conditions are tough".

Round 1 to Gen Z, but the margin is narrowing fast.

Round 2: who's actually got more money

Finder surveyed 2,000 UK adults through Censuswide between 12 and 14 January 2026. The age bands don't map perfectly onto generation labels — millennials in 2026 straddle the 25-34 and 35-44 bands, Gen Z straddles 18-24 and part of 25-34 — so read these as age bands, not clean generational verdicts:

Source: Finder UK savings statistics, Censuswide survey of 2,000 GB adults, 12-14 January 2026 (page updated 9 June 2026).

The UK average across all ages is £19,214, but that's heavily skewed by the over-55s. Strip them out and the average for everyone under 55 is £9,888.

Notice also that the average barely moves between 35-44 and 45-54 — it actually dips. Balances don't climb steadily with age; they stall in the years when housing, childcare and everything else lands at once.

Round 2 to millennials, mostly because they've had a decade's head start.

Round 3: the split inside each generation

This is the finding that matters more than either of the first two.

Around one in five people in both generations has no savings whatsoever. Finder puts it at 20% for Gen Z (their definition: 18-29) — the highest of any generation — and 17% for millennials (30-45). Kent Reliance, using a different sample and definitions, found 21.3% of millennials with nothing saved.

At the same time, 18.2% of Gen Z have already built pots above £10,000, and in Q1 2026 Kent Reliance found 19% of Gen Z saving over £1,000 a month.

So a generation can simultaneously be the most savings-active and have the most people with nothing. Both facts describe the same group because that group is pulling apart into two: people with enough disposable income to save aggressively, and people with none at all. Averages hide this completely — which is why "the average 25-year-old has £X" is close to useless as a personal benchmark.

If you have nothing saved and you're reading a stat about a generational average, the honest read is that the average is describing somebody else's circumstances, not a standard you're failing to meet. Our guide to building an emergency fund from zero is written for exactly that starting point.

What each generation is saving for

The motivations split cleanly, and they explain a lot of the behaviour difference (Kent Reliance, Q2 2026):

• Gen Z: house purchase and holidays jointly top the list (both 10.9%), with starting a business at 5.7%. Milestone-driven.
• Millennials: travel (13.0%), children's future (11.7%), retirement (8.8%). Aspiration plus responsibility.
• Gen X: retirement (18.5%) and later-in-retirement planning (14.5%) — and 48.1% cite a lack of disposable income as a barrier, the highest of any generation.

Nationally, holidays and travel top the list at 13.4%.

There's an ambition gap too. Nationwide's 2026 savings trends research found UK adults planned to save an average of £7,535 across the year, while 25-34s were aiming for £14,912 — nearly double. The same research found 62% of 25-34s would consider a structured savings challenge like the 100 envelope challenge or a no-spend month, and that one in ten UK adults planned to save nothing at all.

Where the Bank Rate leaves both generations

Money in a savings account is currently earning something real, which hasn't always been true. The Bank of England held Bank Rate at 3.75% on 30 July 2026 on a 6-3 vote, with three members voting to raise it to 4% on concerns about energy-driven inflation. The next decision is 17 September 2026.

That matters more to Gen Z than millennials in one specific way: if you're building a first emergency fund, a decent easy-access rate does meaningful work. The top easy-access cash ISA was paying 4.61% AER including a 12-month bonus as of 2 September 2026 (Moneyfacts). On £2,700 — roughly the 18-24 average — that's about £124 over a year, versus roughly £53 in an account paying the sort of rate a lot of high-street current accounts offer on savings pots.

Not life-changing. But it's free, it takes twenty minutes, and it's the highest-return hour of admin available to most people under 30.

The rule change that hits both, and only both

From April 2027, the annual cash ISA allowance drops to £12,000 for under-65s. Over-65s keep the full £20,000.

Read that again in generational terms: the cut applies to every Gen Z and millennial saver in the country, and to no one in the Silent Generation. The 2026/27 tax year is the last full year at £20,000.

Halliwell's own comment on the index was pointed about this — she argued recent ISA changes "risk doing the opposite of what was intended", because "the people who need the most support to save are precisely the ones most likely to disengage when the rules become harder to navigate".

Practically, if you're going to save a meaningful amount in cash over the next 18 months, doing it inside an ISA wrapper this tax year is worth more than doing it next year. We've covered what the cash ISA cut means and what to do before April 2027 in full.

Where to put it, whichever generation you're in

The right home depends on the timeline, not the birth year.

Money you might need within five years — emergency fund, house deposit, wedding, moving costs — belongs in cash, protected by the FSCS up to £120,000 per person per firm (the deposit limit rose from £85,000 on 1 December 2025).

Money you won't touch for five years or more has a better long-run chance in a Stocks & Shares ISA than in cash — but the value can fall as well as rise, and FSCS protection covers the provider failing, not your investments losing money. That's a genuine risk, not a formality.

If you're comparing more broadly before picking, our best investing apps in the UK guide covers all three side by side, and our best cash ISA rates roundup tracks the current table.

What to actually do this month

1. Find out where you stand. Not against a generational average — against your own outgoings. Three to six months of essential costs is the standard target; one month is the realistic first milestone. A free budgeting app makes this a five-minute job rather than a spreadsheet evening; we've compared Emma, Snoop and Plum.
2. Move the emergency fund somewhere that pays. If it's sitting in a current account earning nothing, that's the single easiest fix on this list.
3. Use this tax year's cash ISA allowance if you're saving in cash. £20,000 this year, £12,000 from April 2027 if you're under 65.
4. Separate the timelines. Short-term money in cash, long-term money invested. Mixing them is what causes people to sell investments at the worst possible moment.
5. If you're just starting a career, get the pension match first. It beats everything else here on pure return. Our first graduate salary guide walks through the order.

The honest verdict

Gen Z are saving more often. Millennials have saved more. Millennials had the better quarter. And roughly one in five people in each generation has nothing put away at all.

The generational framing makes for a good headline and a poor benchmark. If you want a number to measure yourself against, use months of expenses covered rather than a national average — it's the only version of the question that has anything to do with your actual life.

FAQ

Who saves more in the UK, Gen Z or millennials? Gen Z save more often; millennials hold more. In Q2 2026, 42.4% of Gen Z said they were saving more than usual — the highest of any generation for the second quarter running — against 39.9% of millennials, though millennials were the only generation whose savings activity rose quarter-on-quarter (Kent Reliance SaveUp Quarterly Savings Index, published 9 July 2026). On balances, Finder's January 2026 survey of 2,000 UK adults put average savings at £2,699 for 18-24s, £11,023 for 25-34s and £13,379 for 35-44s, so millennials are ahead simply through having had longer to build up.

What is the average savings amount for Gen Z in the UK? There isn't one clean figure, because surveys split by age band rather than generation. Finder's January 2026 survey found 18-24 year olds hold an average of £2,699, with 60.9% having £1,000 or less and 9.4% having more than £10,000. Kent Reliance's Q2 2026 index, which uses a wider Gen Z definition, found 18.2% of Gen Z already hold savings pots above £10,000. Both can be true — averages are dragged down by the large share with nothing saved.

How many young people in the UK have no savings at all? Around one in five. Finder's January 2026 survey found 20% of Gen Z (18-29) and 17% of millennials (30-45) have no savings whatsoever, with Gen Z the highest of any generation. Kent Reliance's Q2 2026 index separately found 21.3% of millennials with no savings. Across all UK adults, 16% — about 8.9 million people — have nothing saved (Finder, 2026).

How much should I have saved by 30 in the UK? There's no official target, and comparing yourself to an average is mostly unhelpful because averages are skewed by a minority with large balances. A more practical benchmark is coverage: three to six months of essential outgoings in an instant-access account, built up from a starter goal of one month. On the UK's average personal spend of roughly £1,152 a month (Finder, using ONS household spending data), that's a starter target near £1,150 and a full target of roughly £3,500-£7,000.

Why are millennials saving more in 2026 when Gen Z used to lead? Millennials were the only generation to increase savings activity quarter-on-quarter in Q2 2026, rising to 39.9%, while most others fell (Kent Reliance, 9 July 2026). Their stated motivations are travel (13.0%), their children's future (11.7%) and retirement (8.8%) — goals with real deadlines attached. Gen Z still lead overall at 42.4%, but their net agreement score fell from 18.5% in Q1 to 9.1% in Q2, so the gap narrowed rather than reversed.

Does the April 2027 cash ISA change affect Gen Z and millennials more? Yes, directly. From April 2027 the cash ISA allowance drops to £12,000 a year for under-65s while over-65s keep the full £20,000, so the cut applies to essentially every Gen Z and millennial saver and to none of the Silent Generation. The 2026/27 tax year is the last full year at £20,000, which is why the practical advice for both generations right now is to use this year's allowance rather than wait.

Where should young UK savers put their money in 2026? For money you might need within five years, a cash ISA or instant-access savings account: the top easy-access cash ISA rate was 4.61% AER including a 12-month bonus as of 2 September 2026 (Moneyfacts), while Lightyear's cash ISA pays 3.75% AER tracking the Bank of England base rate with no bonus to expire. For money you won't touch for five years or more, a Stocks & Shares ISA gives a better long-run chance of beating inflation, but the value can fall as well as rise and there's no FSCS protection against investment losses.

This is general information, not financial advice. Savings rates, ISA rules and the figures quoted are current as of 4 September 2026 and change often — check the provider's own page and GOV.UK before acting, and consider speaking to a qualified adviser about your situation. Money held in a Stocks & Shares ISA can fall as well as rise, and you may get back less than you put in.
