Case study: managing a £1.25m pension and ISA portfolio in midlife

Building a seven-figure investment and retirement portfolio by middle age is no mean feat – even when joining forces with a loved one.

Aside from needing to have earned a good wage and enjoyed generous company pensions over the years, it still requires diligence, nous and graft, especially for parents who are tasked with balancing multiple and competing financial priorities.

An investor I recently spoke to, and her spouse, invested their way to a pot exceeding £1 million by the time she was 50, bringing two children into the world along the way. An amazing achievement.

In a deeply unfortunate turn of events, her husband passed away late last year, leaving behind the investor and their two children.

“Financial security feels more important than it did before,” she says.

The loss of a loved one can have a devastating emotional and financial impact on surviving family. While the grief will take time to pass, thankfully her and the children, aged 15 and 12, remain in a financially comfortable position, owing to some prudent planning over the years and sensible decision-making since inheriting the estate proceeds.

The investor is now focused on supporting herself and the wider family unit’s near- and long-term futures.

Since her husband passed, she’s spent time getting her affairs in order. Alongside a life insurance payout, he left everything, including his pension and individual savings account (ISA) to her. The spousal exemption means there was no inheritance tax (IHT) to pay.

The ISA monies topped up her own ISA via an additional permitted subscription (APS), while the pension is housed in a self-invested personal pension (SIPP) with the facility to make tax-free withdrawals at any point. The minimum pension age, currently 55 but rising to 57 in 2028, doesn’t apply to inherited pension funds.

Last year she maxed out her pension and ISA allowances and invested some of the life insurance proceeds into a venture capital trust (VCT) – a tax wrapper that encourages investment in early stage, high-growth companies in exchange for tax perks. The investor subscribed before 6 April 2026, so enjoyed the more generous 30% upfront relief before it fell to 20%.

“I think the VCT will be a one-off as I had some spare cash from the life insurance. It’s not something I see myself doing every year,” she says.

Looking ahead to retirement

In terms of portfolio size, the investor has around £850,000 in her SIPP, and roughly £250,000 in stocks and shares ISAs. A further £140,000 is in her current workplace pension, bringing the total to around £1.25 million, excluding savings, the family home and VCT.

As the investor is in her early 50s, and is still working as a management consultant, she has no plans to retire just yet. She has, however, recently dropped to a four-day week, in part to avoid the punitive 62% effective tax rate that applies on income between £100,000 and £125,140 due to the gradual withdrawal of the personal allowance.

While her earnings would still breach the six-figure threshold, she savvily uses pension salary sacrifice to keep her just below the tax trap and beef up her retirement savings in the process.

“I’m very happy to pay the tax I owe, but I don’t want to pay more tax than I need to. If there are sensible ways to avoid it, I’ll explore them,” she says.

The investor is very much focused on building retirement funds right now but has also started to ponder how she would prefer to leave the workforce.

“I very much like the idea of a phased approach. I wouldn’t go cold turkey - that’s how people can get unstuck. I want to retire to something but also don’t want to leave it too late,” she says.

The investor currently travels both with work and in her spare time and would like this to continue into retirement. She also has a broad and varied list of hobbies that keep her busy now and will do once she decides to pack up work: “I go to the gym and have thought about doing personal trainer qualifications. I’m also learning Spanish and am soon starting piano lessons.”

Keeping things simple

How people choose to invest is a personal thing and typically determined by several factors. At one end of the scale are the stock pickers, comfortable with the grunt and time required to construct some or all their portfolio by selecting individual shares. At the other end are investors who prefer a hands-off approach, happy with strategies which offer broad and diversified global market exposure, typically with low fees.

The investor sits very much in the latter camp, keeping things uber-simple across hers and her children’s tax wrappers, using a single fund: the Vanguard FTSE Global All Cp Idx £ Acc (BD3RZ58) fund.

“That allows me to free up time and money for things that are fun,” she says, adding: “I may consider moving to the [new] exchange-traded fund (ETF) equivalent in future [Vanguard FTSE Global All-Cap ETF USD Acc GBP (LSE:VALL)], as the charges are lower, but I want to see how it performs and works in practice first.”

Bringing several plans under one roof

One of the lesser broadcast benefits of pensions and ISAs is that you can transfer to different platforms and providers without the money leaving the tax wrapper. This means no tax charges are triggered, and in most cases, there are no costs involved.

The investor recently consolidated her pension and ISA portfolio with ii, including pension schemes from former workplaces.

“When I left my previous employer, I was frustrated that the pension provider wouldn’t let me pay the fees directly from my bank account. They insisted on selling down investments, so I took the decision to move to a SIPP,” she says.

Planning throughout the generations

Intergenerational planning is racing up the agenda for many family units, driven by a combination of stricter inheritance tax (IHT) rules and a tidal wave of financial challenges facing younger people.

“My parents are getting older and realising that they haven’t been gifting money [to avoid IHT] as they should have,” the investor says.

She adds that the matter is “preying on their mind” so they’ve decided to meet with an independent financial adviser to get expert help.

Moving down the generations, like any loving parent, the investor is keen to financially support her children into early adulthood and beyond, funding Junior ISAs and Junior SIPPs, to harness the tax efficiencies these products offer.

“My children are starting to gain an awareness of what their savings might do for them, but they’re equally aware that they need to do stuff, too.”

One consideration for Junior ISAs is that the child can access the money at age 18 and spend the funds however they please. Yet research conducted by ii a couple of years ago suggests such fears rarely come to pass. The investor says she hopes her children make sensible decisions with the money and recognises the role she can play here.

“My job as a parent isn’t just to sock the money away, but also to help my children understand about credit cards, debts and investments so they realise the value of money. I don’t want them to assume everything is always paid for. There’s something motivating about having to manage your money.”

Her eldest has entered GCSE exam year and has already chosen his preferred subjects for sixth form: history, politics, and economics. “Like mother, like son,” the investor says.

And one of his recent ideas suggests his mother’s financial acumen is already rubbing off. “My son wanted to buy something and came up with a repayment scheme if I were to lend him the money. It was a very low interest rate of 16p on a £100 loan, but I feel that mindset is as important as the money going aside.”

Reframing ‘painful lessons’

Any successful investor will, of course, have learnt a thing or two along the way. In terms of any wisdom she would pass to younger generations, her main advice is simply to get going.

“Time in the market matters far more than worrying about finding exactly the right moment to invest, and it is very easy to spend so long trying to optimise things that you don’t actually do anything,” she says, adding: “I also think there is real value in making mistakes. It is much easier to learn from your own mistakes than somebody else’s.”

The investor and her late husband racked up around £28,000 worth of debt in their 20s, excluding the mortgage, a figure that could’ve snowballed if not swiftly addressed.

She describes this as a “pretty painful lesson” but one that made her more financially savvy. “I certainly wouldn’t recommend getting into debt as an investment strategy. But I do think the experience shaped how I have approached money ever since.”
