AJ Bell Ready-Made Portfolios vs Vanguard LifeStrategy: Which Costs Less Over 20 Years?

AJ Bell offers five ready-made portfolio options ranging from Cautious to Adventurous, each built from a mix of passive index trackers and actively managed funds. The key difference from pure passive offerings like Vanguard LifeStrategy: AJ Bell blends active and passive management, arguing this gives better risk-adjusted returns.

The portfolios are rebalanced quarterly by AJ Bell's investment team. You don't pick individual funds — you choose a risk level and they handle the rest. For investors who find fund selection overwhelming, this removes the biggest barrier to getting started.

Platform charges sit at a maximum of 0.25% annually, with online dealing from £1.50 per trade. But because ready-made portfolios are managed as a single holding, you don't pay per-trade dealing fees. The ongoing charge figure (OCF) for the underlying funds typically adds another 0.30-0.50%, bringing total costs to roughly 0.55-0.75% per year.

Each portfolio targets a different equity/bond split. The Cautious option holds roughly 30% equities and 70% bonds, while Adventurous pushes to 85%+ equities. This mirrors the structure of Vanguard's LifeStrategy range, but with active fund managers making tactical calls within each band. Whether that active management adds value after fees is the central question — and the historical evidence on active vs passive investing favours passive funds over the long run.

Here's where most reviews get this wrong: they compare platform fees in isolation. What actually determines your returns is the total cost — platform fee plus fund OCF plus any dealing charges.

On a £50,000 portfolio:

• AJ Bell Ready-Made: 0.25% platform + ~0.45% OCF = ~0.70% = £350/year
• Vanguard LifeStrategy: 0.15% platform + 0.22% OCF = 0.37% = £185/year
• DIY index tracker on iWeb: £0 platform (one-off £100 fee) + 0.12% OCF = ~£60/year after year one

Over 20 years at 7% growth, that £165/year difference between AJ Bell and Vanguard compounds to approximately £7,800 in lost returns on a £50,000 initial investment. The gap widens dramatically with larger portfolios — at £200,000, you're looking at over £31,000 in additional costs.

AJ Bell does cap its SIPP platform charge at £120/year for funds (shares have different rules). This means portfolios above £48,000 in funds pay a flat £120 regardless of size — making AJ Bell progressively cheaper per pound as your pot grows beyond that threshold.

The HMRC tax relief on pension contributions means a higher-rate taxpayer effectively gets 40% of their SIPP contribution back. On a £10,000 contribution, that's £4,000 in tax relief. Even with AJ Bell's higher fees, the net return after relief dwarfs any savings account. The question is purely AJ Bell vs cheaper platforms — not AJ Bell vs cash.

Vanguard locks you into Vanguard funds. That's the trade-off for low fees. If you want to hold individual shares, investment trusts, or third-party funds alongside your core portfolio, you can't do it on Vanguard's platform.

AJ Bell offers access to thousands of funds, shares listed on the London Stock Exchange and international markets, investment trusts, ETFs, and gilts. For a SIPP investor building a retirement portfolio that includes both a ready-made core and satellite holdings — say, a FTSE 100 tracker plus some individual dividend shares — AJ Bell is the only option of the two that supports this.

AJ Bell is also FCA-regulated and listed on the FTSE 250 with over 673,000 customers. It's been a Which? Recommended provider for seven consecutive years. For investors who want platform stability and don't fancy moving providers every few years to chase the lowest fee, that track record carries weight.

The Bank of England base rate at 3.75% also means uninvested cash in your SIPP earns meaningful interest. AJ Bell pays interest on cash balances — check their current rates against the base rate to see if you're getting a fair deal.

For SIPP investors specifically, the fee comparison takes on extra weight because pension contributions benefit from tax relief. A basic-rate taxpayer contributing £800 gets topped up to £1,000 by HMRC. Higher-rate taxpayers claim an additional 20% through self-assessment, making the effective cost of a £1,000 pension contribution just £600.

This tax relief compounds the impact of platform fees. Every pound lost to charges is a pound that would have been amplified by relief and compounded over decades. On a 30-year investment horizon — typical for someone in their 30s opening a SIPP — a 0.33% fee difference (AJ Bell's 0.70% vs Vanguard's 0.37%) on a £100,000 pot costs roughly £28,000 in foregone growth.

The current Bank of England base rate of 3.75% also affects the opportunity cost calculation. Cash in your SIPP earns interest, but it won't keep pace with inflation over time. The real question for SIPP investors isn't whether to invest — it's which platform gives you the best net return after all charges.

AJ Bell's SIPP has no setup fee and no exit fee for standard transfers. The annual management charge caps at £120 for funds. If you hold shares directly, there's a separate custody charge capped at £42 per year. These caps are AJ Bell's strongest competitive advantage for larger portfolios.

If you're comparing ready-made portfolios specifically, three alternatives deserve serious consideration:

Vanguard LifeStrategy — Five risk-graded funds (20/40/60/80/100% equity) at 0.22% OCF on a 0.15% platform. The cheapest mainstream option for pure passive investors. No frills, no individual shares, no active management.

InvestEngine — 0% platform fee on their managed portfolios, with a typical OCF of 0.12-0.20% on the underlying ETFs. The catch: limited fund range and a newer platform. But for pure cost-minimisation, nothing beats a 0% platform charge.

Nutmeg (now part of JPMorgan) — Managed portfolios with platform fees from 0.25-0.75% depending on portfolio type. More expensive than AJ Bell for equivalent risk levels, but offers socially responsible options and a polished app experience.

For ISA investors, the comparison shifts slightly. AJ Bell caps stocks and shares ISA platform charges at the same 0.25%, making it competitive for smaller portfolios. But the ISA allowance cap of £20,000 per year means fee differences are less dramatic than with large SIPPs — on a full ISA contribution, you're comparing roughly £35 vs £74 per year between Vanguard and AJ Bell.

The sweet spot for AJ Bell's ready-made portfolios is an investor with £30,000-£80,000 who wants a managed solution but also values having access to the full platform for future self-directed investing. Below £30,000, InvestEngine or Vanguard makes more financial sense. Above £80,000 in funds, AJ Bell's £120 SIPP cap makes it increasingly competitive — but at that level, you probably have the confidence to build your own portfolio from low-cost index trackers.

Notice the crossover: AJ Bell's SIPP cap means it's actually cheaper than Vanguard for portfolios above roughly £80,000. This is the detail most comparison articles miss.

The worst use case: someone with a small pot who's paying 0.70% total costs on a cautious portfolio earning 4-5% nominal returns. At that point, more than 15% of your annual return is going to charges. A cash ISA paying 4.68% with zero platform fees would deliver better net returns with less risk.
