Regular investing is one of the simplest and most effective ways to build long-term wealth. You invest a fixed amount every month, regardless of what the market is doing. No timing decisions, no fuss — just consistent growth over time.
What Is Regular Investing?
Regular investing means setting up a standing order to invest a fixed sum (say £50 or £100) into a chosen fund or shares every month. The money is taken automatically on a set date and invested for you.
The core principle behind it is pound‑cost averaging: because you invest the same amount each month, you automatically buy more units when prices are low and fewer when prices are high. Over time, this smooths out the impact of market volatility.
Why Regular Investing Works
Removes the Timing Decision
Trying to pick the “right” moment to invest is nearly impossible — even professional fund managers get it wrong. Regular investing takes that stress away entirely.
Builds a Habit
Automating your investments turns saving into a habit rather than a decision you have to make each month. Once it’s set up, it runs on autopilot.
Low Minimums
Most UK platforms let you start with £25–£100 per month. You don’t need a lump sum to begin.
Encourages Discipline
When markets fall, regular investors benefit — they buy more units at lower prices. It turns volatility from a threat into an advantage.
Top UK Platforms for Regular Investing
| Platform | Fund Fee (Ongoing Charge) | Share Dealing Fee | Minimum Monthly Investment |
|---|---|---|---|
| Vanguard | 0.15% platform fee | N/A (funds only) | £25 |
| Hargreaves Lansdown | 0.45% platform fee | £3.50 per trade (free for funds) | £25 |
| AJ Bell | 0.25% platform fee | £1.50 per trade | £25 |
| Interactive Investor | £11.99/month flat fee (free on some plans) | £3.99 per trade | £25 |
Vanguard
The cheapest option if you’re happy investing in Vanguard funds only. A flat 0.15% platform fee with no dealing charges. Ideal for hands-off investors who want index funds at rock-bottom cost.
Hargreaves Lansdown
The most popular UK platform. Free fund dealing and a wide selection of funds, ETFs, and shares. The 0.45% platform fee is higher than Vanguard, but you get more choice and a polished app.
AJ Bell
A strong middle ground — lower platform fees than HL (0.25%) and cheap share dealing at £1.50. Good for investors who want both funds and shares without paying over the odds.
Interactive Investor
Best for larger portfolios or investors who want a flat monthly fee. At £11.99/month, it’s cost-effective once your portfolio exceeds around £15,000–£20,000.
How Much Should You Invest?
There’s no “right” amount — the best amount is whatever you can consistently afford. Here are some guidelines:
- £25–£50/month — A solid starting point. Over 20 years at 7% average annual return, £50/month becomes roughly £26,000.
- £100/month — Gets you to around £52,000 over 20 years.
- £200/month — Over 20 years, that’s roughly £104,000.
The most important thing is to start. You can always increase the amount later as your income grows.
What to Invest In
Global Index Fund
The simplest option for most people. A global index fund (such as the FTSE All‑World or MSCI World) gives you instant exposure to thousands of companies across the world. One fund, broad diversification, minimal effort.
Target‑Date Fund
If you’re investing for a specific goal (like retirement in 25 years), a target‑date fund automatically adjusts its risk level as the target year approaches. It starts aggressive and becomes more conservative over time — a true set-and-forget option.
Balanced or Mixed Fund
A fund that holds a mix of shares and bonds — typically 60/40 or 80/20. Suitable if you want growth but with slightly less volatility than a pure equity fund.
Setting Up Regular Investing
- Open a platform account — Choose one from the list above and complete the sign-up process.
- Pick your fund — Search for a global index fund or target-date fund.
- Set up a standing order — Choose your monthly amount and the date you want it taken.
- Turn on dividend reinvestment — Make sure any income from the fund is automatically reinvested rather than paid out as cash.
- Leave it alone — Resist the urge to tinker. Check it once a year, not once a week.
Common Mistakes to Avoid
- Stopping when markets fall — This is the worst time to stop. You’d be selling low and missing the recovery.
- Checking too often — Daily or weekly checks lead to emotional decisions. Monthly or quarterly is plenty.
- Chasing performance — Don’t switch funds every time one underperforms. Stick with a diversified global fund.
- Forgetting about fees — Small differences in fees compound over decades. A 0.5% fee difference can cost thousands over 20 years.
