Healthcare practice working capital covers the gap between paying clinicians, laboratories, stock and rent and being paid by insurers, NHS commissioners, employers and patients. A revolving credit facility suits recurring timing gaps, invoice finance can fund invoices owed by NHS and corporate customers, and a merchant cash advance can suit card-heavy self-pay clinics. Lenders look at the income mix, how long each payer takes to settle, and whether the shortfall is timing or a sign of losses.
This page is for private clinics and independent healthcare practices whose bank balance does not keep pace with their diary: a physiotherapy practice waiting on insurer claims, a private GP service carrying pathology bills before patients settle, an occupational health provider invoicing employers on 60-day terms, or a clinic delivering NHS-commissioned activity and waiting for the reconciliation. Smart Funding Solutions is a broker: we search our panel of 300+ lenders for facilities that match how your practice is paid, from around £10,000 to £500,000+, with larger facilities available in suitable cases. For other clinic borrowing, see our healthcare practice finance hub. Pharmacies, whose cash cycle is dominated by NHS drug reimbursement, are covered on pharmacy finance.

A limit you draw on when bills fall due and repay as income arrives, paying interest only on what you use. It suits clinics with a steady but lumpy timing gap, such as waiting on insurers each month. See revolving credit facilities. The trade-off is that it can become permanent borrowing if the underlying gap is never fixed.
Invoice finance advances most of the value of invoices owed by businesses and public bodies, so it can work well for NHS-commissioned work, occupational health contracts and corporate wellbeing programmes. Many providers will not fund invoices to individual patients or medico-legal debts that depend on a claim settling, and insurer receivables are judged case by case. Selective invoice finance lets you fund a single large contract rather than the whole ledger.
For aesthetics, physiotherapy and other clinics where most patients pay by card, a merchant cash advance is repaid as a percentage of card takings, so repayments ease in a quiet month. It usually costs more overall than a term loan, so compare the total repayable rather than the monthly effect.
A fixed sum over a short term, suited to a one-off need such as stocking up before a seasonal campaign or covering the gap while a new NHS or corporate contract beds in. See working capital loans. Lenders we work with for smaller, fast-moving facilities include iwoca and YouLend, alongside many others.
Indemnity premiums can often be paid monthly through premium finance, and a VAT or corporation tax bill can be spread with a tax loan. HMRC may also agree a Time to Pay arrangement if you cannot pay on time, which should be discussed with HMRC before the deadline.
Healthcare costs tend to be paid earlier and more rigidly than income arrives:
Some of the gap can usually be closed without finance. Practices that tighten these points often need a smaller facility, or none:
Our guide to calculating working capital shows how to measure the gap once these changes have bedded in.
Illustration only, with round hypothetical figures and no rates. A private musculoskeletal clinic bills £60,000 a month. Half is self-pay by card, a third is insurer-funded and the rest is an occupational health contract invoiced monthly on 60-day terms.
Short-term finance used to cover a loss-making month only postpones the problem. Stacking a merchant cash advance on top of a revolving facility and a term loan can take more of each day's takings than the clinic can spare. Invoice finance brings minimum terms and fees, and some facilities notify your customers. Before borrowing, test whether the gap is seasonal, structural or growth-driven; each calls for a different answer, and sometimes the right answer is a conversation with an insurer or commissioner about payment terms.
how income splits between self-pay, insurers, NHS commissioners and employers, because each is funded differently and some cannot be funded against at all.
how long insurer and employer balances take to clear, and whether old disputed items are building up.
whether the practice is profitable over a full year, so the facility bridges a timing gap rather than funding a deficit.
payment terms, reconciliation rules and notice periods in NHS and corporate contracts, which decide how safe that income is to lend against.
how steady monthly card income has been, for a merchant cash advance or any facility repaid from daily takings.
current borrowing, premium finance and any HMRC arrears, which reduce the headroom for a new facility.

Most working capital facilities for clinics need personal guarantees from directors. Borrowing of £25,000 or less by sole traders and small partnerships can be regulated consumer credit, which brings additional protections.
How the main business finance structures work. Lenders set their own terms, so treat this as a guide to the questions to ask.
| Option | How you repay | Security | Often used for |
|---|---|---|---|
| Unsecured business loan | Fixed instalments, usually monthly | No charge over assets; a personal guarantee is usually required | Growth, stock, tax bills and cash flow |
| Secured business loan | Fixed instalments, often over a longer term | A charge over property or other assets | Larger sums, property and refinancing |
| Revolving credit facility | Interest on what you draw; repay and redraw | Varies by lender and case | Recurring or uneven cash flow gaps |
| Merchant cash advance | A share of future card takings | No charge over assets | Card-taking businesses with uneven months |
| Asset finance | Regular payments over the life of the asset | The asset being financed | Equipment, vehicles and machinery |
| Invoice finance | Settled as customers pay their invoices | Your unpaid invoices | Businesses waiting on customer payment |
General information only. Every lender has its own criteria, and all finance is subject to status.
A private clinic can have five or six different payers, each with its own timing. Listing them is the most useful thing you can do before speaking to a lender, because the right facility depends on which ones are slow.
| Payer | Typical timing pattern | What causes delays |
|---|---|---|
| Self-pay patients | Paid on the day by card, or in advance for packages | Little delay, but refunds and chargebacks on cancelled courses |
| Private medical insurers | Paid after the claim is submitted and processed | Missing pre-authorisation, coding errors, shortfalls the patient then owes |
| NHS commissioners | Usually monthly, sometimes against a plan with later reconciliation to actual activity | Activity data queries, contract variations, year-end reconciliations |
| Employers and occupational health contracts | Invoiced monthly on agreed credit terms | Purchase order requirements, approval chains, disputes over attendance |
| Solicitors instructing medico-legal reports | Often paid only when the claim settles | Case length, which can run to many months or longer |
NHS-funded activity delivered by independent providers is generally governed by the NHS Standard Contract, which sets out how and when the commissioner pays. Read the payment terms in your contract, not the general assumption that the NHS pays promptly: a disputed activity figure can hold back part of a month's income for a long time. Our guide to funding NHS contracts looks at contract cash flow in more depth.
We start with your payer mix and bank statements, work out where the gap really sits, and approach lenders whose facility type fits it. Lenders decide on the application; we handle the comparison, the paperwork and the questions in between. If the cash pressure comes from a planned project rather than day-to-day trading, see practice refurbishment finance or healthcare practice acquisition finance. It is free to enquire; any broker fee is disclosed separately before you proceed.
Sometimes. Some providers will fund insurer receivables where claims are well documented and paid reliably, but many prefer invoices to businesses and public bodies. Clinics with a mixed ledger often use a revolving facility for insurer timing and invoice finance only for NHS or corporate contracts.
A common starting point is enough to cover the slowest payers' average delay plus the next large annual bill, such as indemnity renewal. Your own figures matter more than any rule of thumb, so map a year of monthly income and costs by payer to see the real low point.
Lenders see the cash in your bank statements but will treat unused package balances as money you owe in treatments. Relying on package sales to fund day-to-day costs can leave the clinic short when those treatments are delivered.
An overdraft from your own bank can be the simplest option if it is available and large enough, but it is repayable on demand. A committed revolving facility usually gives more certainty over the term, at the cost of fees whether you use it or not.
Yes, a merchant cash advance provides a lump sum repaid as a share of future card takings, so repayments rise and fall with the clinic's income. It can suit self-pay clinics with strong card volumes, but it is usually more expensive than a term loan, and the total cost should be compared carefully. Our page on merchant cash advance explains how it works.
