Second Lien Loans For UK SMEs: What To Know Before Borrowing

If you’re growing a business, cash flow can feel like it’s always one step behind your ambition.

Maybe you’re scaling operations, hiring, buying stock, funding R&D, or bridging a gap to profitability. But you’ve already got senior debt in place (like a bank facility), and your lender won’t increase the limit.

That’s where a second lien loan often enters the conversation. It can be a useful funding tool for UK SMEs and startups - but it comes with specific legal and commercial risks that you’ll want to understand before you sign.

Below, we break down what a second lien loan is, how it typically works for UK businesses, what to watch for in the documents, and how to protect your business as much as possible when taking one on.

What Is A Second Lien Loan?

A second lien loan is a loan where the lender takes security over a borrower’s assets, but that security is subordinated in priority to another lender’s security.

In plain terms:

• The “first lien” (senior) lender has the first claim over certain secured assets if the business defaults or becomes insolvent.
• The “second lien” lender also has security over assets, but they sit second in the repayment queue.

This ranking matters most in a downside scenario (default, enforcement, administration or liquidation). If secured assets are sold, the first lien lender gets repaid first from the proceeds, and the second lien lender is paid only after the first lien is satisfied.

Second Lien Loan vs Unsecured Loan

From a business owner’s perspective, one key point is that a second lien loan is still a secured facility - it’s just secured in a “subordinate” position.

That often means:

• pricing can sit somewhere between senior secured debt and fully unsecured lending (depending on the deal, credit profile, and security value), and
• terms may be tighter than a senior facility because the lender’s risk is higher.

Why Does “Lien” Language Show Up In The UK?

In England & Wales, finance documents more commonly talk about “security”, “charges” and “priority” rather than “liens”. But the commercial idea is similar: who gets paid first out of secured assets (and who gets control over enforcement).

If you’re not sure how this works, it’s worth understanding charge on a company concepts early, because priority and enforcement rights will drive a lot of the negotiation.

How Does A Second Lien Loan Work In Practice For UK Businesses?

Most commonly, a second lien loan sits behind an existing senior facility.

For example, your company might already have:

• a bank overdraft;
• a revolving credit facility (RCF);
• an asset finance arrangement; or
• a term loan secured by a debenture and fixed/floating charges.

A new lender then offers additional funding on the basis that they will also take security - but they agree (or are required) to rank behind the senior lender.

Priority Is Usually Managed Through An Intercreditor Agreement

In many second lien structures, you’ll see an intercreditor agreement (sometimes called a deed of priority). This is a contract between the lenders (and usually signed by the borrower too) setting out:

• who ranks first and second over different assets;
• how enforcement works (who can enforce, and when);
• standstill periods (when the second lender must “wait”);
• how recoveries are shared; and
• what happens if debt is refinanced or amended.

Even if the second lender takes security, their ability to enforce (and the timing of enforcement) may be restricted by this agreement, depending on the negotiated terms.

What Assets Might Be Secured?

Security packages vary, but could include some combination of:

• fixed charges over plant, equipment, or real estate;
• floating charges over stock and receivables;
• security over bank accounts;
• IP-related security (for some businesses this is critical);
• share security (less common for SMEs, but possible); and
• personal guarantees (particularly in smaller owner-managed businesses).

Sometimes the second lender’s security mirrors the first lender’s security (but ranks behind it). Other times, the second lender takes security over a different “slice” of assets, depending on what the senior lender permits.

Where the arrangement involves a comprehensive security package, you may see a debenture-style document (sometimes also referred to as a general security agreement) forming part of the suite.

Why Would An SME Or Startup Consider A Second Lien Loan?

Second lien funding is rarely a “first choice” - it’s usually a tool used when your business is in a particular stage or position.

Common reasons UK SMEs and startups consider second lien funding include:

1) You Need Growth Capital But Senior Debt Is Maxed Out

Your bank might be comfortable up to a certain leverage ratio, asset coverage level, or covenant package - and no further.

A second lien lender may be willing to provide additional capital because they’re pricing for higher risk and relying on enterprise value or future growth rather than just asset coverage today.

2) You Want To Avoid Equity Dilution

If you raise equity, you’re selling part of the business. For founders and existing shareholders, a second lien loan may look attractive because it provides funding without issuing shares.

That said, debt has to be repaid - so the question becomes: is this sustainable leverage for your business, or does it create pressure that affects decision-making later?

3) You’re Bridging To A Future Event

Sometimes second lien loans are used as “bridge” financing to:

• a planned fundraising round;
• a refinancing;
• a sale of the business;
• an acquisition; or
• a major contract milestone.

This can work well if the timeline is realistic and the documents don’t make the bridge impossible to cross (for example, by restricting future fundraising or imposing aggressive repayment triggers).

4) You’re Funding An Acquisition Or Expansion

If you’re acquiring another business or opening new sites, you might need extra capital quickly. A second lien lender may be able to move faster than traditional lenders - but the trade-off is usually tougher terms and tighter protections for the lender.

Key Terms In A Second Lien Loan You Should Understand (And Negotiate)

Most funding deals feel “commercial” until something goes wrong. The real value of legal review is spotting the clauses that matter in real life - especially when cash flow gets tight.

Here are some of the big terms you’ll want to understand in any second lien loan.

Interest, Fees, And The Real Cost Of Capital

Second lien loans often come with layered pricing, for example:

• higher interest rates than senior facilities;
• arrangement fees and exit fees;
• default interest;
• PIK (payment-in-kind) interest, which accrues rather than being paid monthly; and/or
• monitoring fees or lender legal costs.

Make sure you model the “all-in” cost, not just the headline rate.

Covenants And Reporting Requirements

Covenants are promises about how your business will operate financially and operationally.

Typical covenants may include:

• minimum cash balance requirements;
• EBITDA or revenue targets;
• leverage ratios;
• limits on additional borrowing; and
• regular reporting (monthly management accounts, budgets, board packs).

For SMEs, the practical question is: can you realistically comply, every month, even in a bad quarter?

Events Of Default (EODs)

Events of default are the triggers that allow a lender to demand repayment, enforce security, or renegotiate from a position of strength.

Common EODs include:

• missed payment;
• breach of covenant;
• insolvency-related events;
• material adverse change clauses (be careful - these can be broad);
• cross-default (a default under the senior loan triggers default under the second lien loan); and
• incorrect statements or warranties.

Cross-default is particularly important in second lien structures. If your senior lender has an issue, your second lender can suddenly have one too - and you can end up dealing with multiple stakeholders at the worst time.

Restrictions On Your Freedom To Operate

Second lien lenders often restrict what you can do without consent, such as:

• selling assets or granting new security;
• paying dividends;
• changing your business model materially;
• making acquisitions;
• issuing new shares; or
• entering into related party transactions.

If you’re a scaling startup, these restrictions can matter just as much as pricing, because your growth strategy may depend on being agile.

Liability Allocation And Clauses That Aren’t Really “Boilerplate”

Even in finance documents, you’ll see clauses that allocate risk in subtle ways - like indemnities, exclusions, and caps (or the absence of caps).

It’s worth understanding how limitation of liability clauses work in commercial contracts generally, because they can influence how far your exposure can extend beyond “just repaying the loan”.

What Documents And Due Diligence Will You Need Before You Sign?

A second lien loan isn’t just “sign a loan agreement and receive funds”. In practice, there’s usually a bundle of documents and a lot of moving parts - especially because there’s already a senior lender involved.

Here’s what to expect.

The Core Legal Documents

While every deal is different, common documents include:

• Facility/loan agreement setting out the commercial terms, covenants and default provisions (this is often where a loan agreement templates discussion starts - but in practice, second lien deals are usually bespoke).
• Security documents (debenture/general security, charges, account security, possibly IP security).
• Intercreditor agreement / deed of priority between lenders.
• Corporate approvals (board minutes, shareholder resolutions if required under your articles or shareholders’ agreement).
• Legal opinions (sometimes requested, depending on the lender and size of the deal).

If your transaction involves moving or transferring rights (for example, if the lender later sells the debt), it’s useful to understand deed of assignment concepts, because assignment mechanics often appear in finance documents.

Execution Formalities Matter

Second lien loan documents are often executed as deeds (especially security documents), and execution errors can create real enforceability issues.

It’s not the most exciting part of fundraising - but it’s one of the easiest ways to accidentally create a mess.

Make sure you understand the basics of executing contracts and deeds in England and Wales, including who can sign, whether a witness is needed, and how to sign on behalf of the company correctly.

Due Diligence: What The Lender Will Ask For

Expect the lender (and their lawyers) to request a due diligence pack. This could include:

• constitutional documents and Companies House filings;
• cap table and details of shareholders (and any Shareholders Agreement constraints on new debt);
• existing facility agreements and security documents;
• material contracts (customer and supplier agreements);
• financial statements and forecasts; and
• details of any disputes or threatened claims.

A common pinch point is that your existing senior lender documents may restrict further borrowing or granting additional security. You’ll want to review those restrictions early, before you spend time negotiating a second lien term sheet that can’t be implemented.

Be Clear On How Repayment Actually Works

Before signing, you should be able to answer (in plain English):

• When do we start repaying principal?
• Are repayments fixed, cash sweep-based, or bullet at maturity?
• Can we refinance without penalty?
• What happens if we miss our forecast?
• What must we get consent for, day to day?

If the answers are unclear, that’s a sign the documents need tightening before you proceed.

Key Takeaways

• A second lien loan is secured lending where the lender ranks behind a senior (first lien) lender in priority over assets.
• Second lien funding can help UK SMEs and startups raise growth capital when senior debt is capped, but the trade-off is often higher cost and tighter controls.
• Priority and enforcement rights are usually governed by an intercreditor agreement (or deed of priority) - and this can restrict what the second lien lender can do, and when, depending on the agreed terms.
• Key terms to focus on include covenants, cross-default provisions, events of default, consent requirements, fees, and how repayment works in practice.
• Second lien loans typically involve multiple documents (loan agreement, security documents, priority arrangements, corporate approvals), and execution formalities are critical.
• Because these facilities can affect future fundraising, refinancing, and even day-to-day operational flexibility, it’s worth getting legal advice before you commit.
