A Self-Invested Personal Pension (SIPP) is one of the most powerful retirement wealth-building tools available exclusively to UK investors. The government tops up every contribution with tax relief, and every penny of growth sits sheltered from HMRC’s fingers while a portfolio grows.
In fact, even starting from scratch at 45, a million-pound retirement pot is still firmly within reach when following a simple long-term investing strategy.

The maths behind the million
If the plan is to retire at 67, that leaves a 45-year-old with 22 years of high-quality compounding ahead of them. But to achieve the goal of reaching a seven-figure territory with a simple index tracker generating a near-8% annualised return, a total of £1,400 will need to be invested each month.
That’s obviously a substantial sum. And while the tax relief benefits from a SIPP means an investor will only need to contribute £1,120 of this each month, it nonetheless remains a big stretch for many investors.
The good news is there’s a nifty way to close the gap by potentially as much as 60% to just £432 each month.
The power of stock-picking
Instead of matching the stock market’s returns, shrewd investors can aim to beat it, earning a higher return and building impressive retirement wealth with far less capital.
Perhaps a perfect example of this in action over the last 22 years is Oxford Instruments (LSE:OXIG). As a quick crash course, this is a FTSE 250 scientific technology business supplying materials analysis, semiconductor, and healthcare tools to academic and commercial customers worldwide. And since June 2004, the stock’s delivered a total return of 1,817%!
That works out to an average of 14.4% a year. And anyone who’s been investing £432 (or £540 after tax relief) each month over the last 22 years at this rate of return is now sitting on an impressive £1m pension pot.
Still worth considering?
The group’s latest full-year results were published earlier this month and revealed a story of genuine resilience in what’s been a generally difficult period.
The first half was disrupted by tariff uncertainty and US academia funding cuts, which hit order flow and revenue timing. Yet the second half delivered a strong recovery, with revenue returning to growth, adjusted operating profit rebounding 15.4%, and the full year finishing slightly ahead of expectations.
Overall, order intake climbed a respectable 6.4% to £450.4m, placing the book-to-bill ratio at 1.06. In other words, more orders are coming in faster than old ones are being fulfilled, creating visible demand and momentum for the business, driven in large part by the semiconductor manufacturing sector that Oxford Instruments supplies.
Having said that, there are a few risks to watch. Most notably, the geopolitical landscape is also creating some headaches. The enterprise manufactures in multiple countries and sells globally, making it sensitive to trade restrictions, rare earth supply chains, and US academic funding policy.
So what’s the verdict?
Oxford Instruments is not a flashy growth story. It is a disciplined, innovation-led business with a 67-year track record of solving hard scientific problems for the world’s leading researchers and manufacturers.
While maintaining a 14%+ annualised return might prove challenging, the company nonetheless looks like a promising long-term compounder. That’s why I’m already considering this business for my own SIPP.
