Vanguard vs Hargreaves Lansdown vs AJ Bell ISA Compared UK 2026
If you’re saving into an ISA in the UK, you’ve got three serious contenders fighting for your money. Vanguard keeps costs razor thin, Hargreaves Lansdown offers a massive choice of investments, and AJ Bell sits somewhere in the middle with competitive fees. This article breaks down which platform wins for different types of investors, so you can stop wasting time and start saving smartly.
| Platform | Annual Fee | Best For |
|---|---|---|
| Vanguard | 0.15% to 0.23% | Passive investors |
| Hargreaves Lansdown | 0.45% plus fund fees | Active investors |
| AJ Bell | £42 to £252 yearly | Regular monthly savers |
Vanguard ISA: The Low-Cost Leader
Price
Vanguard charges between 0.15% and 0.23% per year on your ISA balance. There’s no additional trading fee when you buy or sell their own funds and ETFs. If you’re investing £10,000, you’re paying around £15 to £23 annually, which is genuinely hard to beat.
Pros
- Lowest fees in the market by a clear margin
- Simple, straightforward pricing with no hidden charges
- Excellent range of low-cost index funds and ETFs
- Ideal if you’re buying and holding for decades
- You own your funds outright, not via a platform
Vanguard’s fee structure is genuinely transparent. You know exactly what you’re paying, and there’s no surprise charges for anything. Their in-house funds are brilliantly cheap, and they’re designed for long-term passive investing where you’re not constantly tinkering.
Cons
- Only 85 funds available, all Vanguard branded
- Can’t access other fund managers’ products
- Not ideal if you want lots of choice or flexibility
- Minimal guidance or research tools on the platform
The main issue is that Vanguard only sells their own funds. If you want to invest in a fund from Fidelity, BlackRock, or any other manager, you simply can’t do it through Vanguard. This severely limits your options if you want a mixed portfolio.
Who It Suits
Vanguard is perfect if you believe in passive, low-cost investing and you’re happy buying their funds. You should pick Vanguard if you’re making regular investments over 20+ years and you don’t want to constantly trade. It’s also ideal if you hate paying fees and you want complete ownership of your investments.
Skip Vanguard if you want access to funds from multiple managers or if you’re an active trader who makes frequent changes. It’s also not the platform for you if you want personal investment guidance or research articles to help pick funds.
Hargreaves Lansdown ISA: The Choice Champion
Price
Hargreaves Lansdown charges 0.45% per year on your ISA, capped at £252 annually. This is added on top of the fund’s own fees, which can range from 0.1% to 1% or more depending on what you buy. On a £10,000 balance, you’re paying around £45 per year in platform fees alone.
There’s no charge for regular monthly investments, which is a genuine perk if you’re building your savings steadily. However, occasional traders and people making large lump-sum investments will pay nothing extra beyond the percentage fee.
Pros
- Access to over 80,000 funds from all major managers
- Excellent investment research and ratings tools
- No charges for regular monthly contributions
- Strong customer service and support team
- Ability to hold multiple investment types in one place
The sheer range of funds available is Hargreaves Lansdown’s biggest strength. You can pick and choose from the world’s best fund managers, whether that’s Fidelity, Vanguard, BlackRock, or anyone else. Their research tools help you make informed decisions, which is valuable if you’re not sure what to buy.
Cons
- Higher platform fees compared to Vanguard
- Overall costs can spiral if you’re buying higher-cost funds
- Fees cap at £252, which is good, but percentage model still expensive
- Can tempt you to over-trade or chase performance
The problem with Hargreaves Lansdown isn’t the platform itself, it’s that the 0.45% fee encourages you to pick higher-cost funds. Combined with a fund that costs 0.8%, you’re suddenly paying 1.25% annually. Over 30 years, this difference versus Vanguard adds up to tens of thousands of pounds.
Who It Suits
Hargreaves Lansdown is ideal if you want choice and flexibility in your investments. Pick it if you’re comfortable researching funds yourself and you don’t mind paying for that choice. It’s also good if you’re making regular monthly investments and want the platform fee cap to work in your favour.
Avoid Hargreaves Lansdown if you’re a passive investor who just wants to buy low-cost index funds. It’s also not ideal if you’re cost conscious and want to minimize fees, because there are cheaper options available.
AJ Bell ISA: The Middle Ground
Price
AJ Bell charges a flat fee depending on your account type. For an adult Stocks and Shares ISA, you’ll pay £3.50 per month, which equals £42 per year. There’s no percentage fee, which means once you’ve paid that flat rate, trading additional funds costs nothing more.
AJ Bell also charges you per trade in their General Investment Account, but we’re focusing on ISAs here where the flat fee applies. This pricing model works brilliantly if you’re a regular investor making multiple purchases throughout the year.
Pros
- Flat annual fee of £42, which is dirt cheap
- Unlimited trades with no per-transaction cost
- Access to 80,000+ funds, similar to Hargreaves
- Good quality research and tools included
- Excellent value for regular monthly savers
The £42 annual fee is genuinely competitive, especially if you’re buying multiple funds. Once you’ve paid that fee, you can trade as much as you want without extra charges. This makes AJ Bell fantastic for people who like to rebalance their portfolio or add new investments regularly.
Cons
- Flat fee model means wealthy investors don’t get much advantage
- Still more expensive overall than Vanguard for long-term holders
- Can encourage over-trading because there’s no per-trade cost
- Smaller brand, less name recognition than competitors
If you’ve got £100,000 in your ISA, you’re still paying just £42 per year. That’s genuinely good value. However, if you’re only investing £5,000 and you’re not planning to make other trades, Vanguard’s percentage fee might work out slightly cheaper.
Who It Suits
AJ Bell is perfect if you’re a monthly saver who wants to keep fees low and simple. Pick it if you want access to lots of funds without paying a percentage fee. It’s also ideal if you like to tinker with your investments and rebalance regularly, because extra trades won’t cost you anything.
Skip AJ Bell if you’re a pure passive investor who buys once and forgets about it. Vanguard will win on fees in that scenario. Also avoid AJ Bell if you’ve got a very small ISA balance under £5,000, because the flat fee represents a bigger percentage cost.

Which One to Pick: Real Scenarios
Scenario 1: You’ve Got £50,000 and Want to Invest It Once
Vanguard wins here, and it’s not even close. You’ll pay around £75 to £115 in your first year, while Hargreaves Lansdown costs £252. If you invest in a Vanguard fund charging 0.1%, your total cost is around 0.25% to 0.33%. Hargreaves Lansdown with an average fund at 0.5% costs you 0.95% annually. Over 30 years, that’s easily £30,000+ in extra fees.
Pick Vanguard unless you specifically want to invest in funds they don’t offer. If you do need a wider range, go with AJ Bell at £42 per year, which is still far cheaper than Hargreaves Lansdown.
Scenario 2: You Save £500 Every Month Into Your ISA
AJ Bell is your winner here. You’ll pay £42 yearly no matter how many times you buy. If you’re making monthly purchases into diversified funds, you’ll spend around £252 per year at Hargreaves Lansdown with their fee cap. Vanguard on an average balance of £30,000 costs about £70 per year, so it’s actually competitive, but you’re limited to their 85 funds.
Go with AJ Bell for flexibility and simplicity. You get low fees, unlimited trading, and access to any fund you want. It’s the sweet spot for regular savers.
Scenario 3: You Want to Research and Pick Individual Funds Carefully
Hargreaves Lansdown is best here. Their research tools, ratings, and fund notes are genuinely helpful when you’re trying to pick between hundreds of options. You’ll pay £252 yearly maximum, which is worth it for serious fund researchers who want professional-quality information.
AJ Bell is a decent second choice at £42 per year with decent tools, but Hargreaves Lansdown’s research edge justifies the extra cost if fund picking matters to you.
Scenario 4: You’re a Busy Professional With £100,000+
Vanguard wins easily if you want passive index funds. You’ll pay 0.15% to 0.23%, which is around £150 to £230 yearly. That’s genuinely cheap, and you don’t have to think about anything ever again. Pick their global stock index fund and forget about it for 20 years.
If you want someone to have researched fund options for you, Hargreaves Lansdown isn’t bad, but honestly at this wealth level you should consider a proper financial adviser who charges hourly fees instead.
Questions People Ask
Can I Move My ISA Between These Platforms?
Yes, you can. It’s called an ISA transfer, and it’s usually free or low cost. You simply complete a transfer form with your new provider, and they’ll handle moving your money from your old platform. The cash stays in the ISA wrapper the entire time, so you don’t lose any tax benefits.
It typically takes two to four weeks. I’d recommend doing it only when you’ve genuinely outgrown your current platform, not constantly switching just to chase slightly cheaper fees. The time and effort usually isn’t worth chasing marginal gains.
What’s the Difference Between These Platforms and a Robo-Adviser?
These platforms let you pick what to buy. A robo-adviser like Nutmeg or Wealthify picks automatically based on your answers to a questionnaire. Robo-advisers charge around 0.25% to 0.5% and often only let you choose a risk level, not individual funds.
If you want complete control, use one of these three platforms. If you want hands-off investing and don’t mind slightly higher costs, a robo-adviser might suit you better. Most people building long-term wealth prefer the control and lower costs of a platform like these.
Can I Hold Other Investments Alongside My ISA?
Yes, absolutely. You can have a General Investment Account (GIA) on the same platform for money beyond your ISA allowance. You’ll pay capital gains tax on profits in your GIA but not in your ISA. All three platforms let you hold both simultaneously.
The ISA should always be your first choice for your savings because it’s tax-free. Only use the GIA when you’ve maxed out your £20,000 yearly ISA allowance.
Which Platform Has the Best Customer Service?
Hargreaves Lansdown gets consistent praise for customer service responsiveness and helpfulness. However, all three platforms offer phone and email support, and modern investors increasingly don’t need to call anyone. Your choice of platform shouldn’t hinge on customer service unless you genuinely expect to need lots of hand-holding.
Vanguard’s support is fine for simple questions, and AJ Bell’s is reliable. If you’re buying a simple portfolio of index funds, you won’t need support from any of them. Save yourself some money and go with the cheapest option.
Conclusion: The Clear Winner Depends on Your Style
For most UK investors, AJ Bell wins the overall value competition at £42 yearly with unlimited trading and 80,000 funds. It sits perfectly between Vanguard’s limited choice and Hargreaves Lansdown’s higher costs. You get flexibility without overpaying for it.
However, if you’re a true passive investor planning to buy once and hold for decades, Vanguard’s 0.15% to 0.23% fee absolutely cannot be beaten. The difference compounds to truly meaningful amounts over 30 years. Hargreaves Lansdown is only worth considering if you want professional-quality research tools and you’re genuinely going to research funds carefully.
Pick AJ Bell for regular monthly saving, Vanguard for pure passive buy-and-hold, and Hargreaves Lansdown only if you want premium research tools and don’t mind paying for choice. Start saving today, because the years matter far more than which platform you pick.
