Skip the banks and explore peer-to-peer lending as a real funding alternative for UK small businesses

Peer-to-peer lending is a regulated way for UK limited company SMEs to borrow from individual investors through online platforms, rather than through a traditional bank, and it has become a recognised part of the UK commercial finance market.

In simple terms, peer to peer lending connects borrowers directly with individual lenders through online platforms, eliminating the need for traditional banks as intermediaries. In business finance, this usually means a company borrows money through a specialist platform, while investors fund the loan in small parts. Some people still search for peer2peer lending, but the regulated UK term is usually peer to peer finance, P2P lending, marketplace lending or loan-based crowdfunding.

This guide is for UK SMEs, brokers, and advisers considering peer-to-peer lending as a business finance option. It looks at how peer to peer loans work, who is involved, the main benefits and risks for borrowers and lenders, how tax, an innovative finance isa and bad debt relief work, the application process, alternatives to P2P lending, and how FundingSearch fits into the wider UK lending ecosystem.

For businesses facing restrictive bank criteria or slow decision times, P2P lending can offer a faster, more flexible route to funding and, in some cases, competitive pricing in a changing finance market. In the UK, peer-to-peer lending platforms are regulated by the Financial Conduct Authority (FCA), which ensures that they adhere to specific standards and practices to protect investors and borrowers. FCA rules tightened significantly after 2019, and from 2020 to 2024 many retail P2P brands exited or changed model, while business and property-focused lending platforms remained active. FundingSearch is not a peer lending platform, lender or broker; it is a UK deal origination marketplace that helps brokers and SMEs compare regulated peer lenders alongside banks and other lenders.

What is peer-to-peer lending and how does it work?

Peer-to-peer lending connects borrowers directly with individual lenders through online platforms, eliminating the need for traditional banks as intermediaries.

Peer lending is a many-to-many online model: a peer to peer lender uses an online marketplace to connect borrowers with investors, and multiple investors can fund one business loan while spreading money across different companies instead of relying on traditional lending methods.

• A UK limited company submits a loan request through the platform, providing detailed information such as business details, turnover, profits, trading history and the loan amount required so potential lenders can review it.
• The lending process is largely digital through specialised online platforms, which often automate loan matching, underwriting and repayment administration from application to servicing.
• The platform requests accounts, bank statements, director information and sometimes live accounting data from tools such as Xero or Sage.
• Peer-to-peer lending platforms typically conduct credit checks and assess borrowers' financial history to determine their creditworthiness and set interest rates accordingly.
• The platform either sets interest rates by risk band or uses an auction model where investors bid the higher rates or better rates they are willing to accept.
• Investors lend directly to borrowers, while the platform administers the debt under FCA permissions, including Article 36H of FSMA 2000.
• Once funded, borrowers repay capital and interest, usually monthly, over common terms of 6–60 months. Some platforms also offer a secondary market where investors can sell loan parts to other investors after issue, subject to platform availability and market conditions.
• Typical uses include working capital, stock purchase, equipment, marketing, bridging a VAT bill or refinancing more expensive debt.

P2P investments can be diversified across many small increments, mitigating the impact of any single borrower defaulting. That does not remove risk, but it is one reason investors may add peer to peer investments to an investment portfolio or overall investment portfolio.

Who is involved in peer-to-peer business lending?

A typical UK peer to peer business loan includes several parties, each with a different role.

• The borrower is usually a UK limited company SME with filed accounts, trading history and a clear purpose for the money.
• Investors may be retail investors, high-net-worth individuals, sophisticated investors or institutional investors looking for investment opportunities and potential profits.
• New regulations introduced by the FCA in 2019 limit new investors to investing no more than 10% of their ‘investable assets' in peer-to-peer lending, unless they have received independent financial advice.
• The platform acts as the loan originator and administrator, running credit scoring, collecting repayment and distributing interest to other investors.
• Due diligence can include Companies House searches, director checks, credit checks, management accounts, bank account review and site visits for property-backed lending.
• Brokers and advisers use marketplaces such as FundingSearch's commercial finance lending platform to compare peer to peer lending with other business finance products before approaching lenders.
• Security providers and guarantors may be involved where personal guarantees, asset charges or property charges are required.

Funding Circle was one early mover in UK SME P2P, helping to popularise the model after 2010, but today the market includes a wider mix of specialist financial institutions, alternative lenders and property-focused platforms.

Benefits of peer-to-peer lending for UK SMEs

P2P became more mainstream after 2010 because some SMEs found traditional financial institutions slow, restrictive or unwilling to fund smaller cases, and preferred a faster structure with more flexible terms and conditions than traditional lending methods.

• P2P lending provides an alternative financing route that can often be easier to qualify for than traditional bank loans, offering loans to individuals and small businesses.
• Online journeys are usually faster than some high-street banks, with decisions often made in days rather than weeks.
• Loan sizes can range from £5,000–£25,000 at the low end to £1m+ for larger secured or property-backed facilities, though P2P loans can vary in size depending on the platform and borrower profile, so they may not meet every business’s funding needs.
• This lending model can help some borrowers secure better rates than traditional loans, while lenders may earn higher returns than savings accounts.
• Actual pricing depends on risk grade, term, sector, security and affordability.
• Because it is debt, not equity, owners do not give away shares, voting rights or control of the business.
• Some platforms look at recent trading, cash flow and live accounting data rather than only historic scores.
• FundingSearch helps brokers compare peer to peer lending against invoice finance, asset finance, commercial mortgages and other products, so the borrower does not assume P2P is automatically the best fit, using commercial finance broker software that streamlines lender matching and documentation

Easily accessible online

• UK businesses can access peer lending through web platforms with guided applications, document upload, digital ID checks and e-signatures.
• Many platforms give indicative eligibility and interest rates within minutes using a soft search and basic company information.
• FundingSearch lets brokers pre-qualify clients with verified data and quickly see which P2P lenders are likely to consider the deal by leveraging its SME lending deal origination platform.
• This can reduce wasted applications, especially where the borrower has a niche sector, unusual structure or time-sensitive requirement.

Range of platforms and loan types

• Peer-to-peer lending can be categorised into three main types: lending to individuals, lending to small businesses, and lending against property.
• Lending to individuals involves funding personal loans, where borrowers repay the loan over an agreed time period, often with higher interest rates than traditional banks.
• Lending to small businesses can include straightforward loans or invoice financing, where businesses borrow against future cash from invoices.
• Lending against property typically involves funding development projects, where loans are secured against the property being developed, providing some security for lenders.
• For SMEs, examples include unsecured working capital, a loan secured against property, or a facility supported by personal guarantees.
• This variety improves choice, but it also makes comparison harder without a broker or matching platform.

From small to larger peer loans

• A £30,000 peer loan might help an online retailer buy seasonal stock before peak sales.
• A £250,000 facility could support a fit-out for a growing hospitality or professional services business.
• A £1m property-backed facility might fund development projects, refurbishment or bridging.
• Smaller unsecured loans often carry higher interest rates because there is less security.
• Larger loans are more likely to involve detailed underwriting, valuations, legal work and charges over assets, and from an investor perspective funds are often locked in for the duration of the loan term because some P2P loans are illiquid investments with no secondary market.

Risks involved with peer-to-peer lending for borrowers and lenders

P2P lending is not risk-free. Borrowers take on legal repayment obligations, while lenders can lose money if a borrower defaults or a platform fails.

For borrowers and investors alike, P2P lending involves both risks and rewards. For borrowers, the main risks include higher interest rates than secured bank debt, fees, personal guarantees and damage to credit if repayments are missed. For lenders, the main risks are borrower default, platform failure and liquidity risk if they cannot exit before term, so understanding your own risk tolerance matters.

The FCA's 2019 rules for loan-based peer-to-peer and crowdfunding platforms require clearer risk warnings, appropriateness tests and wind-down plans. However, peer-to-peer lending is not covered by the Financial Services Compensation Scheme (FSCS), meaning that investors do not have the same protections as traditional bank depositors.

Peer-to-peer lending is not covered by the Financial Services Compensation Scheme, meaning investors could lose all their capital if a borrower defaults or if the platform fails. Put plainly, you could lose all your money, so nobody should invest more money than they can afford to risk.

Investors in peer-to-peer lending can expect overall returns between 7% and 9% per year, with the potential for higher returns depending on the risk taken. But future performance is not guaranteed. Default rates for peer-to-peer loans can vary significantly, with default risk being one of the main factors investors should weigh against return expectations, and some platforms reporting rates as low as 0.84% while others may experience rates as high as 70% for riskier borrowers.

Interest rates and overall cost

• Interest rates on peer to peer business loans are usually higher than secured bank loans, but may be lower than credit cards or merchant cash advances.
• Higher-risk borrowers, longer terms and weak security can lead to double-digit annual rates, and borrowers with a poor credit score may face higher interest rates, while those with a good credit score may access stronger pricing.
• P2P platforms typically charge origination fees, processing fees or service fees, which can increase the overall cost of borrowing.
• Other fees may include arrangement fees, servicing charges, valuation fees, legal fees and early repayment fees.
• For example, a £100,000 three-year loan at 10% plus a 2% arrangement fee can cost far more than a secured bank loan at 7%, even if the monthly payment looks manageable.
• SMEs should compare the total cost of capital, not just the headline interest rate.
• Platforms conduct credit checks on the business and often its directors.
• After submitting a formal application, peer-to-peer lending platforms conduct credit checks on borrowers to assess their eligibility for loans.
• Hard searches can temporarily affect credit files, especially if several applications are made at once.
• Missed repayment on a peer loan can make future business finance harder or more expensive.
• A clean repayment record may help demonstrate creditworthiness to banks, a building society, other financial institutions or other lenders.
• A matching service such as FundingSearch helps target suitable lenders before applications are submitted.

Personal guarantees and security

• Many UK P2P business loans require personal guarantees from directors, especially if the loan is unsecured.
• A personal guarantee means that if the company cannot pay, the guarantor can be pursued personally.
• Personal assets, including savings or property, may be at risk.
• Secured loans may also involve a legal charge over property, equipment or other business assets.
• Security can reduce interest rates, but it gives lenders stronger recovery rights if default occurs.
• Directors should take independent legal advice before signing guarantees.

Default and collections

• If a business misses a payment, the platform will usually issue arrears notices and contact the borrower.
• The borrower may be asked for updated financial information and a repayment plan.
• If arrears continue, the platform may begin collections, enforce security or pursue guarantors.
• Platforms must treat borrowers fairly, but they also have a duty to protect investors.
• A realistic default timeline might involve one missed payment, two months of arrears discussions, a proposed reschedule, and legal enforcement if no solution is agreed.

Tax, Innovative Finance ISA, and how interest is treated

For investors, P2P is an investment, not a savings account. Interest from peer to peer platforms is normally taxable unless held in a qualifying ISA wrapper.

• UK individual investors may pay tax on P2P interest above their personal savings allowance.
• Current allowances are usually £1,000 for basic-rate taxpayers, £500 for higher rate taxpayers and £0 for additional-rate taxpayers.
• The Innovative Finance ISA was launched in 2016 and allows qualifying peer to peer investments to earn interest tax-free within the ISA wrapper.
• The annual ISA subscription limit is £20,000 for the 2025–26 tax year, shared across cash, stocks and shares, and IFISA products.
• Even inside an innovative finance isa, capital remains at risk and peer to peer loans are not protected by the financial services compensation scheme.
• HMRC bad debt rules can allow irrecoverable P2P loans held outside an ISA to be offset against interest from other peer loans in the same tax year, subject to conditions.

HMRC guidance on Innovative Finance ISA qualifying investments explains that eligible platforms must have the right FCA permissions.

Do you have to pay tax on peer-to-peer interest?

• UK-resident individual investors generally declare and pay income tax on P2P interest above their personal savings allowance.
• Platforms may pay interest gross, so reporting is usually the investor's responsibility.
• A basic-rate taxpayer receiving £1,500 of P2P interest may only be taxed on the £500 above the £1,000 allowance.
• A higher-rate taxpayer receiving £1,500 may be taxed on the £1,000 above the £500 allowance.
• Companies that invest through P2P normally treat interest as part of taxable profits under corporation tax rules.
• Keep statements from every lending platform and seek tax advice if unsure.

Innovative Finance ISA (IFISA) and peer-to-peer lending

• An IFISA lets investors lend through an eligible P2P platform inside an ISA wrapper, so interest does not incur income tax.
• Not all peer to peer platforms offer IFISAs, and eligibility can change with regulation or platform strategy.
• IFISAs do not change the underlying investment risk.
• Loans can still default, platforms can fail, and FSCS deposit protection does not apply.
• Treat an IFISA as a tax wrapper, not a guarantee.

Is peer-to-peer lending right for your business?

P2P can be powerful for some established SMEs with trading history, and while it is not always the cheapest or most suitable option, it may also help businesses with poor credit access funds when banks decline.

• It may suit companies with at least 1–2 years of filed accounts at Companies House, and lower credit scores may still qualify for peer-to-peer loans.
• Stable or growing turnover helps, especially where cash flow clearly supports repayment.
• Start-ups and pre-revenue companies may struggle and may need start-up loans, grants, equity or founder funding instead.
• P2P has been used by professional services firms, online retailers, construction businesses and property-related companies.
• It can support financial inclusion by giving viable SMEs another route when banks decline.
• Borrowers should compare P2P with asset finance, invoice finance, overdrafts and commercial mortgages before committing.
• FundingSearch helps brokers and SMEs view peer to peer lending beside those other options, using verified financial data rather than guesswork, though it may still fall short of larger funding needs for weaker-credit borrowers.

What to consider before approaching a peer-to-peer lending platform

Before you apply, prepare the case as if an underwriter is going to challenge every assumption.

• Gather the last 2–3 years of accounts, recent management accounts and bank statements, plus any available tax returns to show financial and trading history.
• List existing borrowing, monthly repayment commitments and any arrears.
• Check the business credit profile and director credit scores where possible.
• Model affordability against a revenue dip, cost increase or central bank rate movement.
• Decide whether directors are willing to offer personal guarantees or property security.
• Be ready to give detailed information on how the funds will be used and how the borrowing will be repaid, and include a concise business plan if the case is complex or growth-focused.
• Use a broker with FundingSearch to reduce failed applications and unnecessary credit searches.

How to apply for peer-to-peer lending as a UK SME

The application process is usually digital, but strong preparation still matters.

• Most UK adults can apply for peer-to-peer lending, but they must meet certain eligibility requirements set by each platform, which typically include being at least 18 years old, being a UK resident with a UK bank account, and passing identity and anti-money laundering checks.
• The application process for peer-to-peer lending usually involves completing an online form and submitting a loan request with detailed information about the business, its trading history, and the funding purpose, as well as the amount needed.
• The SME explains the purpose of funds and uploads accounts, statements and supporting documents, and the platform may review a credit check as part of its assessment.
• Automated decisioning and AI-driven models may provide a same-day in-principle decision.
• Larger, secured or property-backed loans usually require manual underwriting, valuation and legal review.
• Straightforward unsecured loans may fund within days; complex secured facilities take longer.
• A broker can package the case using FundingSearch integrations with Companies House, Xero and Sage.
• Practical tip: reconcile accounting software, prepare a concise use-of-funds note and show how the business will repay.

Alternatives to peer-to-peer lending for business finance

P2P is one tool in a larger commercial finance toolbox. The right structure depends on purpose, affordability, security and timing.

• Traditional bank business loans may suit strong borrowers seeking lower rates and longer terms.
• Commercial mortgages can fund property purchase or refinance where the asset supports the debt.
• Invoice finance may work better when cash is tied up in unpaid invoices.
• Asset finance can spread the cost of vehicles, machinery or equipment, and specialised asset finance solutions can help structure these purchases without large upfront costs.
• Asset-based lending may support larger SMEs with receivables, stock, plant or property.
• Overdrafts can handle short-term working capital but may be more expensive or callable.
• Trade finance can help importers, exporters and stock-heavy companies fund supply chains, while other alternative funding options for small businesses such as grants or equity may suit different stages of growth.
• Some alternatives offer lower interest rates but require more security, more documents or slower underwriting.
• FundingSearch's AI-driven origination platform helps brokers and advisers compare options across UK lenders using verified financial data.
• The aim should be long-term funding strategy, not simply the quickest short-term loan.

Where FundingSearch fits in the peer-to-peer ecosystem

FundingSearch is a B2B SaaS deal origination and matchmaking platform. It is not a lender, peer to peer platform or broker, but rather a UK business fintech SaaS platform connecting businesses, brokers and lenders

FundingSearch connects UK SMEs, commercial finance brokers and a broad panel of lenders, which may include peer lenders alongside banks, specialist finance providers and other financial institutions, supporting borrowers who might otherwise search for a standalone business and commercial lending platform offering fast, flexible funding options. The platform covers seven commercial finance asset classes: business loans, commercial mortgages, bridging, invoice finance, asset finance, asset-based lending and trade finance, reflecting wider trends in fintech innovation across UK commercial finance.

Its features are especially relevant where a P2P loan could be suitable but is not the only option:

• AI matching algorithms help identify lenders aligned with the borrower's profile.
• Smart lender selection reduces avoidable declines.
• Companies House, Xero and Sage integrations help present clean and accurate applications.
• Brokers can package cases faster and compare P2P against mainstream and alternative finance.
• Lenders receive better-qualified deal flow from businesses that are more likely to fit their criteria.

Founded in 2025 in Sheffield, England, FundingSearch focuses on UK limited company borrowers and the advisers who support them and is profiled in its press kit as a UK fintech platform transforming SME funding. For SMEs, the value is not being pushed toward one type of lending. It is seeing whether peer to peer finance is genuinely appropriate beside the wider market.

If you are considering P2P, start with the basics: understand the risk, compare total cost, prepare your documents and avoid applying blindly. If you are a broker or adviser, FundingSearch can help you assess whether a peer lending route fits the client, or whether another commercial finance product is the stronger match.
