Peer-to-peer business lending involves securing finance from a group of individual or institutional investors rather than directly from a bank. Borrowing is done through a third-party, nowadays usually an online platform, that handles the application, credit assessment and repayments. However, the money itself comes from the investors behind it. Peer-to-peer lending grew really fast through the 2010s after it was first introduced in the UK in 2005, when Zopa launched the world’s first peer-to-peer lending company. Business-focused P2P lending followed not long after in 2010.

The sector in 2026 looks different than it did in the 2010s. The Financial Conduct Authority introduced tighter rules for P2P platforms in 2019, leading to some popular platforms closing to retail investors, and funding for some major business lending platforms shifting away from individuals and towards institutions.

Much of what is written online today about peer-to-peer lending is a retrospective look at where the market was about ten years ago, with some platforms having stopped new lending or closed their retail operations years ago. This guide is written for businesses looking to borrow rather than for people weighing up peer-to-peer investing.

What Is Peer-to-Peer Business Lending?

Often called P2P business lending, peer-to-peer business lending happens when a business looking to borrow has access to individual or institutional investors without going through a traditional bank loan.

Three parties are involved in P2P business lending:

• The business taking the loan.
• The investors whose money funds it.
• The platform that brings the two together, which also handles the credit assessment, collects the repayments and passes them on.

The platform is a connector and, in the traditional P2P model, does not provide the loan itself. It earns fees for arranging and servicing the loan, while the credit risk sits with the investors. That makes it a different proposition from a direct lender, who would otherwise lend from its own balance sheet and carries the lending risk itself.

In the early years of peer-to-peer business lending, the investors were mostly retail individual savers who could put in a few hundred or a few thousand pounds each and spread their money across dozens of loans, rather than funding an entire business loan themselves. The market has since shifted significantly towards institutional funding.

You repay the capital with interest and hand over no shares in your company. Generally described as P2P lending or loan-based crowdfunding. “Marketplace lending” is also used to describe similar platform-based lending models, although the exact structure can vary between providers.

How Peer-to-Peer Business Loans Work

How does peer to peer lending work? The process runs in five stages.

• You apply through the platform: Applications are carried out online almost without exception. Requirements include: filed accounts, several months of bank statements, details of existing borrowing and an explanation of what the money is for.
• The platform assesses you and assigns a risk grade: It runs credit checks on the company and sometimes on the directors as well. That grade determines the interest rate you get, so a stronger profile means cheaper money.
• The loan is listed for funding: On a retail platform, individual investors each fund a slice and the loan fills over hours or days. On a platform funded by institutions, it draws on capital already committed, which is quicker and more predictable.
• The money is released: Funds reach your business account once funding is complete and the documents are signed.
• You repay the platform monthly: When you make your deposits, it gets distributed to the investors and the platform takes its fee along the way.

A few things to note:

• The headline interest rate is only part of what you pay. Most p2p business lending platforms charge an arrangement or completion fee, often deducted from the advance itself, and some add servicing or early settlement fees. Therefore, always ask for the total cost of the facility in pounds over its full term rather than the rate alone.
• Many peer to peer business loans are secured against property or other assets, and a personal guarantee from a director is common even on facilities described as unsecured.
• Expect one to four weeks from application to funds. This is fair for an unsecured facility, and longer where property security has to be valued and registered. 

Who Peer-to-Peer Lending Suits

Peer to peer lending for business works well in some situations and poorly in others.

P2P business lending is a great option for:

• Businesses with two or more years of trading history and healthy accounts. P2P platforms lend according to filed numbers, so yours need to stand up to scrutiny.
• Owners who want a fixed-term loan with predictable monthly repayments and a defined end date.
• Businesses declined by their bank on policy grounds rather than creditworthiness. For example, a bank pulling back from a sector is different from a business being a poor risk, and platforms often take their own view.
• Projects with a clear purpose and a repayment plan behind them, such as buying equipment, fitting out a second site or refinancing costlier debt.

P2P lending is not a great option for:

• Newer companies with limited trading history and accounts. Most platforms want a trading record they can assess.
• Businesses that need money in days. The average platform takes about a fortnight.
• Businesses with seasonal or highly variable turnover. Fixed monthly repayments mean the same repayment even when trade falls, and a February instalment on a summer business bites hard.
• Owners who are unwilling to give a personal guarantee, since most platforms will ask for one.

If those last two points describe your business, revenue-based finance is worth weighing up alongside peer to peer loans. It is unsecured, quick to arrange and assessed on how you trade, and repayments move in step with your card takings rather than sitting at a fixed monthly figure.

The Risks and Drawbacks for Borrowers

Every funding route involves trade-offs. These are the peer to peer borrowing risks that matter most to a borrower are these.

• Funding is not guaranteed: There’s a possibility that a loan listed on a retail platform can fail to fill. Especially for a borrower carrying a higher risk grade, so you can reach the end of the process with no money.
• Rates can sit above a bank’s: In situations where businesses classified as risky are given a loan, the rate reflects said risk. With the P2P rate higher than the banks.
• Fees are easy to overlook: Arrangement fees and platform fees can significantly change the cost of the loan. Read the fee schedule in full before signing.
• Personal guarantees are common: Signing one puts your home, savings or other personal assets behind the company’s debt. Our guide to personal guarantees sets out exactly what you would be agreeing to.
• Repayments do not flex: The monthly figure is identical whether you have had a strong month or a dreadful one.
• Platforms can close: Platforms have historically withdrawn from new lending or exited retail funding. The FCA requires every platform to hold a wind-down plan so existing loans carry on being administered, and it is worth knowing what happens to your facility if a platform stops lending partway through your term.
• Missed payments follow you: A late or missed repayment marks your business credit score like any other borrowing, and makes the next facility costlier or difficult to get.

Is Peer-to-Peer Lending Regulated in the UK?

Yes, but with a huge caveat. Peer-to-peer lending is a regulated business activity in the UK in the sense that platforms carrying out loan-based crowdfunding activities are authorised by the Financial Conduct Authority (FCA). The FCA sets rules for these platforms covering areas such as credit assessments, customer information and how loans are managed if a platform fails. However, the underlying business loan may not itself be FCA-regulated.

For a business borrower, this authorisation does not mean the FCA guarantees your loan or that you will be approved for finance. It means the platform is authorised to carry out the regulated activities listed on its permissions. Therefore, before applying, look the platform up on the FCA Financial Services Register and make sure its status is authorised and that it has the relevant permissions.

You may also be able to take a complaint to the Financial Ombudsman Service (FOS). Eligibility depends partly on the size of your business. For example, the FOS can consider complaints from micro-enterprises and eligible small businesses, subject to its rules and the activity being within its jurisdiction. A micro-enterprise has fewer than 10 employees and annual turnover or a balance sheet that does not exceed €2 million. For eligible small businesses, the thresholds are annual turnover of less than £6.5 million and either a balance sheet total of less than £5 million or fewer than 50 employees. The FOS eligibility guidance for small businesses sets out the thresholds and other requirements.

Alternatives to Peer-to-Peer Business Lending

Peer to peer lending platforms sit within a wider alternative lending market, and several other routes are worth putting side by side before you commit.

• Traditional bank loans

While it’s the cheapest loan available to businesses, there’s a trade-off in terms of speed and eligibility. Banks ask for more, take longer and decline more applications, especially from younger businesses.

• Unsecured business loans from direct lenders

A direct lender uses its own funds, so there is no listing period and no risk of a loan failing to fill. Decisions come faster than a bank’s and no charge is taken over your assets. A personal guarantee is usually required.

• Asset and equipment finance

Where funding a specific purchase, such as a vehicle, machinery or kitchen equipment, the asset acts as the security. That brings the rate down and makes approval easier than an unsecured loan of the same size.

• Invoice finance

If cash is tied up in unpaid invoices, this advances a percentage of the invoice’s value as soon as they are raised. It suits businesses selling to other businesses on credit terms, and grows as your sales book grows.

• Equity crowdfunding

This is equity rather than debt. Business crowdfunding platforms of this kind in the UK raise money by selling shares, so there is nothing to repay, and you give away a slice of ownership and a say in how the business is run. It suits high-growth companies with an exit in mind.

• Revenue-based finance

Repayments move as a percentage of your card takings rather than a fixed monthly sum, so a quiet month costs you less and a busy month clears the balance faster. It suits retail, hospitality and other card-taking businesses where trade rises and falls through the year.

The Bottom Line

Peer to peer lending remains a great funding route for UK businesses, particularly for companies with substantial trading history, good accounts and an asset to secure against. The sector is smaller and more selective than at its peak, so treat it as one option rather than assuming it is the cheapest.

It’s in your best interest to confirm that the platform is on the FCA register. Then, read the fee structure in full so you know the total cost rather than the rate, and confirm in writing whether a personal guarantee is required.

If fixed monthly repayments and the time it takes to get your finance are a big concern, it may be worth considering other options. For example, revenue-based finance from 365 Finance can be an option for businesses, including those without a strong credit profile. We assess funding based on how your business trades rather than relying solely on a credit grade, with repayments that rise and fall with your revenue.
