What peer-to-peer lending actually involves

Peer-to-peer lending, often shortened to P2P, is a way of lending money directly to individuals or businesses through an online platform. You are not putting money in a savings account. You are buying a loan or a share of a loan, and you earn interest when the borrower repays. The platform handles the paperwork, collects payments, and passes your share back to you.

It sits somewhere between saving and investing. Your capital is at risk, and returns are not guaranteed. In the UK, P2P platforms are regulated by the Financial Conduct Authority, but your money is not protected by the Financial Services Compensation Scheme (FSCS). That single fact should shape how you use it.

The rewards: higher potential returns and regular income

The main attraction is yield. With easy-access savings accounts often paying around 4% to 5%, P2P has advertised rates that have historically ranged from about 4% to 8%, depending on the platform and the risk you take. Some platforms offer a steady stream of interest and capital repayments each month, which can suit families who want to supplement their income.

If you hold loans inside an Innovative Finance ISA, any interest is tax-free. That is a real advantage if you have already used your personal savings allowance. Outside an ISA, P2P interest counts as income, so you may owe tax on it.

There is also a practical benefit: P2P can diversify a portfolio that is heavily weighted towards shares or cash. It does not move in lockstep with the stock market, although it has its own risks.

The risks: defaults, illiquidity, and no safety net

There is a real risk of borrower defaults. If a borrower stops paying, you can lose some or all of the money you lent to them. Diversification helps, but it does not remove the risk. A wide spread of loans may soften the blow, yet a recession can push default rates up across the board.

• Capital at risk: You can get back less than you put in. P2P is not a savings account.
• No FSCS protection: If a platform fails, you are not automatically compensated. Your loans may be managed by a third party, but recovery can take time.
• Illiquidity: Many loans run for three to five years. Selling early depends on other investors buying your loans, and you may have to accept a discount or wait.
• Provision funds are not insurance: Some platforms hold a pot of money to cover defaults, but it can be exhausted. It is not a guarantee.
• Tax and fees: Interest outside an ISA is taxable, and platform fees can eat into returns.

How to fit P2P into a family budget

Before you lend a penny, sort out the foundations. Build an emergency fund of at least three to six months' essential spending. Pay off expensive debts, such as credit cards and overdrafts. Keep short-term savings for school uniforms, car repairs, and holidays in a normal savings account.

Only then consider P2P, and only with money you can genuinely afford to lose. A sensible ceiling for most families is 5% to 10% of investable assets. If you are saving for a house deposit, a wedding, or university fees due in the next few years, P2P is the wrong home for that money. The timescale is too uncertain.

Treat it as a long-term, illiquid investment. Do not rely on it for next month's mortgage payment or an emergency boiler repair.

Practical ways to reduce the risk

• Start small: Begin with a few hundred pounds and see how the platform works before committing more.
• Spread your money widely: Aim for at least 100 different loans if the platform allows it. Avoid concentrating on one borrower or sector.
• Check the numbers: Look at the platform's published default rates, recovery rates, and bad debt provisions. Do not just look at the advertised return.
• Reinvest repayments: Keep your diversification steady as loans are repaid.
• Understand the exit: Ask what happens if the platform closes. Read the wind-down plan.
• Review annually: Your circumstances change. A product that suited you two years ago may not suit you now.

Questions to ask before you invest

You do not need to be a financial expert, but you do need to be curious. Ask:

• Is this investment covered by the FSCS? (The answer will be no.)
• What is the historical default rate, and how much has been recovered?
• Are the loans secured against assets, or unsecured?
• Can I withdraw my money early, and at what cost?
• Is the interest tax-free inside an IFISA, and have I used my £20,000 allowance?
• What fees does the platform charge, and how are they taken?

Peer-to-peer lending can be a useful part of a diversified financial plan. It can offer higher returns than cash, and it can feel good to support UK borrowers. But it is not a replacement for a savings account, and it is not risk-free. Be honest about your family's budget, keep your emergency fund intact, and only lend money you could lose without changing your plans. If that sounds too cautious, it is meant to. The risks are real, and the rewards are never guaranteed.
