What is this thing, actually?
Sixteen products you'll bump into as a beginner, each explained twice: once the way a friend would explain it over a cuppa, and once the proper technical way, in case you ever need that too.
Boxes, baskets and ingredients
Most products are just different containers, baskets or ingredients.
Some are wrappers, like ISAs and pensions — a box with tax rules, empty until you put something in it.
Some are the actual investments, like shares, funds, ETFs, gilts and bonds — the things that go in the box.
Some spread your money across many things. Some put it all into one thing.
Your first job is not to pick the best one. It is to work out which of those you are looking at.
The one rule to remember
One thing = more concentrated risk.
Many things = usually more spread out risk.
But spread out does not mean risk-free.
Places to keep money
Cash savings
Usually spreads your riskMoney sat in a bank account earning interest, where the pound amount never falls.
Somewhere to keep money (not an investment)
What people use it for
Your emergency fund and anything you'll need within the next five years.
Does it spread your risk, or focus it?
There is no investment risk at all up to £120,000 per banking licence — the number in your account cannot go down. The quiet risk is inflation: prices can rise faster than your interest, so the same money buys less next year.
Think of it like this
Like keeping food in the fridge rather than the freezer. Nothing dramatic happens to it, but it doesn't last forever either.
The bit that catches people out
Safe from crashes, not safe from inflation. Money left in a poor-paying account for years quietly loses buying power.
Ask this first
Do I have three to six months of bills saved here before I invest anything?
The proper technical definition, if you ever need it
A deposit account at a bank or building society paying interest, protected up to £120,000 per banking licence by the Financial Services Compensation Scheme.
Cash ISA
— Individual Savings Account (cash version)Usually spreads your riskAn ordinary savings account with a tax-free label on it.
A wrapper (a box you put things in)
What people use it for
Saving cash without paying tax on the interest.
Does it spread your risk, or focus it?
Same as cash savings — the pound amount doesn't fall. The ISA part is just a tax wrapper; it changes the tax, not the risk.
Think of it like this
Like a lunchbox. It doesn't change what's inside, it just stops anyone else taking a bite — in this case the taxman.
The bit that catches people out
An ISA is a wrapper, not an investment. A Cash ISA paying less than an ordinary account can leave you worse off even after the tax saving.
Ask this first
Is this rate actually better than the best ordinary savings account after tax?
The proper technical definition, if you ever need it
A tax-free wrapper around a cash deposit account, within the £20,000 annual ISA allowance.
GIA / dealing account
— General Investment AccountDepends entirely on what is insideA normal investment account with no tax perks and no limits.
A wrapper (a box you put things in)
What people use it for
Investing more than the £20,000 a year an ISA allows.
Does it spread your risk, or focus it?
Like the ISA, the account itself is neither risky nor safe. The risk sits in what you buy inside it.
Think of it like this
Like buying a coffee on the high street instead of at work — same coffee, you just don't get the staff discount.
The bit that catches people out
You may owe tax and have to declare it yourself. Most beginners should fill their ISA first.
Ask this first
Have I used my ISA allowance this year before opening this?
The proper technical definition, if you ever need it
An ordinary taxable investment account with no annual limit; gains above the capital gains allowance and dividends above the dividend allowance are taxable.
Pension / SIPP
— Self-Invested Personal PensionDepends entirely on what is insideA retirement pot where the government tops up whatever you pay in, but you can't touch it until your late fifties.
A wrapper (a box you put things in)
What people use it for
Money you genuinely won't need until retirement.
Does it spread your risk, or focus it?
Again a wrapper, so the risk depends on the funds inside. Most workplace pensions sit in broad, well-spread funds by default.
Think of it like this
Like a Christmas savings club that pays you a bonus for joining — brilliant value, but you can't raid it in July.
The bit that catches people out
The money really is locked away. Never pay in cash you might need for a boiler, a car or a rainy month.
Ask this first
Am I already getting every penny of employer match on my work pension first?
The proper technical definition, if you ever need it
A tax-relieved retirement wrapper: contributions receive tax relief at your marginal rate, and money is normally locked until age 55, rising to 57 in 2028.
Things you can buy
ETF
— Exchange-Traded FundDepends entirely on what is insideA basket of investments in one product that you buy and sell like a share.
An actual investment (a thing you own)
What people use it for
Owning hundreds or thousands of companies in a single, cheap purchase.
Does it spread your risk, or focus it?
It can spread your risk because you are not relying on just one company — although the risk depends entirely on what the ETF holds. A global ETF is broad; a single-country or single-theme ETF can be surprisingly concentrated.
Think of it like this
Like buying a ready-made fruit bowl from the supermarket instead of buying apples, bananas, grapes and oranges separately and making the bowl yourself.
The bit that catches people out
Some ETFs are simple and broad, others are narrow, complex or geared up. Always check what is inside.
Ask this first
What does this ETF actually hold?
The proper technical definition, if you ever need it
A pooled fund whose units trade on an exchange throughout the day, usually tracking an index.
Fund
Depends entirely on what is insideA shared pot of lots of people's money, invested together by a manager.
An actual investment (a thing you own)
What people use it for
Handing the picking to someone else instead of researching every company yourself.
Does it spread your risk, or focus it?
Usually well spread, but not always. Some funds hold only twenty or thirty companies, or bet heavily on one theme. Read the top ten holdings.
Think of it like this
Like a meal-kit box. Someone else chose the ingredients and you pay them for the convenience — worth checking they're a decent cook.
The bit that catches people out
The yearly charge comes out whether the fund does well or badly. Most managers don't beat a plain index once fees are paid.
Ask this first
What is the ongoing charge, and what are the ten biggest things it holds?
The proper technical definition, if you ever need it
A collective investment scheme — typically an OEIC or unit trust — priced once a day, where a manager or rule set decides the holdings.
Index fund
Usually spreads your riskA fund that just quietly copies a whole market instead of trying to be clever.
An actual investment (a thing you own)
What people use it for
The cheapest, most boring way to own a whole market at once.
Does it spread your risk, or focus it?
Very well spread if the index is broad — a global index fund owns thousands of companies across dozens of countries. A narrow index, like one country or one sector, is far less spread out.
Think of it like this
Like taking one of every item on the shelf rather than betting the whole trolley on which cereal tastes best.
The bit that catches people out
It will fall in every crash, because it holds everything including the bad bits. Spread out is not the same as safe.
Ask this first
Which index does it track, and how many countries and companies is that?
The proper technical definition, if you ever need it
A passively managed fund that mechanically tracks a published index rather than selecting holdings.
Investment trust
Depends entirely on what is insideA company whose only job is to own other investments, and whose shares you buy like any other share.
An actual investment (a thing you own)
What people use it for
Well-spread exposure, often to things ordinary funds can't easily hold.
Does it spread your risk, or focus it?
The underlying holdings are usually well spread. Two extra wrinkles: the share price can drift away from what the holdings are actually worth, and many trusts borrow money to invest, which magnifies both gains and losses.
Think of it like this
Like buying a share of a landlord's whole property empire rather than one flat — but paying whatever the market feels the empire is worth today, not what it's actually worth.
The bit that catches people out
You can pay more than the holdings are worth (a premium) or less (a discount). Borrowing inside the trust makes bad years worse.
Ask this first
Is it trading at a premium or a discount, and how much has it borrowed?
The proper technical definition, if you ever need it
A closed-ended company listed on the stock exchange whose business is holding a portfolio of investments; its share price can trade above or below net asset value.
REIT
— Real Estate Investment TrustFocuses your risk on one thingA company that owns buildings and passes most of the rent on to shareholders.
An actual investment (a thing you own)
What people use it for
Getting property income without buying, letting or maintaining an actual building.
Does it spread your risk, or focus it?
Spread across many buildings and tenants, but concentrated in one industry — property — and usually one country. When property falls, the whole thing falls together.
Think of it like this
Like owning a slice of a shopping centre rather than a single corner shop. Better than one shop, still entirely dependent on shoppers turning up.
The bit that catches people out
Property is bought with borrowed money, so REITs suffer badly when interest rates rise. The dividend can be cut.
Ask this first
What kind of buildings does it own — shops, offices, warehouses — and who rents them?
The proper technical definition, if you ever need it
A listed property company with special tax treatment, required to pay out most of its rental profits as dividends.
Lending your money out
Gilt
Usually spreads your riskA loan you make to the UK government, which pays you interest and hands your money back on a set date.
An actual investment (a thing you own)
What people use it for
Predictable income and steadying a portfolio that holds shares.
Does it spread your risk, or focus it?
About as low as investment risk gets in the UK, because the borrower is the government. The catch: if you sell before the end date, the price moves with interest rates and you can get back less than you lent.
Think of it like this
Like lending a reliable neighbour money with a written date on the fridge for when you get it back — safe enough, but awkward if you need it sooner.
The bit that catches people out
Gilts are only predictable if you hold to the end date. In 2022 gilt prices fell hard when interest rates jumped.
Ask this first
What is the maturity date, and could I leave the money there that long?
The proper technical definition, if you ever need it
A UK government bond: a fixed-coupon loan to HM Treasury repaid at par on a set maturity date.
Bond
Focuses your risk on one thingA loan you make to a company or a government, in return for interest.
An actual investment (a thing you own)
What people use it for
Income that is usually steadier than shares.
Does it spread your risk, or focus it?
One bond is one borrower. If that company gets into trouble, it can pay late or not at all. A single company bond is nearly as concentrated as a single share, just with a different way of going wrong.
Think of it like this
Like lending a friend £500. Most friends pay you back. The interest is small comfort when one doesn't.
The bit that catches people out
A high interest rate on a bond is a warning, not a bargain. It means the market doubts the borrower.
Ask this first
Who is borrowing my money, and what happens if they can't repay?
The proper technical definition, if you ever need it
A tradable debt instrument issued by a company or government, paying a fixed coupon until maturity.
Bond fund
Usually spreads your riskA basket of hundreds of loans, so no single borrower can hurt you much.
An actual investment (a thing you own)
What people use it for
Getting bond-style income without picking individual borrowers.
Does it spread your risk, or focus it?
Well spread across borrowers, so one default barely registers. But the fund never 'matures', so its price keeps moving with interest rates — you don't get the guaranteed money-back date a single bond gives you.
Think of it like this
Like being one of two hundred people who each lent a tenner, rather than the one person who lent £2,000.
The bit that catches people out
Often sold as the 'safe' half of a portfolio, yet bond funds fell sharply in 2022. Safer than shares is not the same as safe.
Ask this first
Does this hold government bonds, solid company bonds, or high-risk ones?
The proper technical definition, if you ever need it
A pooled fund holding many bonds, with no fixed maturity date of its own.
The riskier end
Commodity
Focuses your risk on one thingA raw material like gold, oil or wheat, bought as an investment.
An actual investment (a thing you own)
What people use it for
A small hedge, usually against inflation or panic.
Does it spread your risk, or focus it?
Very concentrated — you are betting on the price of one substance. It also produces nothing: no profits, no dividends, no interest. Your only return is someone paying more later.
Think of it like this
Like buying a shed full of tinned food hoping the price of tins goes up. It'll never earn you a penny while it sits there.
The bit that catches people out
Prices can halve and stay down for a decade. Keep it small if you hold it at all.
Ask this first
Why would this be worth more in ten years than it is today?
The proper technical definition, if you ever need it
A raw physical good such as gold, oil or wheat, usually accessed through a fund or exchange-traded product rather than the physical item.
Crypto
Focuses your risk on one thingA digital token whose price is set purely by what the next person will pay.
An actual investment (a thing you own)
What people use it for
Speculation. It is not an income investment and it is not a savings product.
Does it spread your risk, or focus it?
Extremely concentrated and extremely volatile. Falls of 70-80% have happened repeatedly. Nothing underneath produces profit, so there is no floor under the price.
Think of it like this
Like buying a rare football sticker. It's worth exactly what the next person in the playground will swap for it — no more, no less.
The bit that catches people out
Not covered by the UK compensation scheme. If the platform collapses or you're scammed, the money is simply gone. Never invest money you'd miss.
Ask this first
Could I lose every penny of this and still be fine?
The proper technical definition, if you ever need it
A digital asset recorded on a blockchain, with no earnings, no regulator behind it and no compensation scheme.
