Business line of credit lenders: draw-down facilities compared

A business line of credit gives you a limit to draw on when you need it, rather than a lump sum on day one. Lenders build these facilities in quite different ways: some are pure revolving limits, some are draw-down loans, and some are tied to invoices or property. This page compares what eight UK lenders publish.

The short answer

Business line of credit lenders give you a limit you can draw, repay and draw again, usually charging interest only on what you use. Among the UK lenders below, published limits run from £1,000 to £5 million, terms from a few months to five years, and some facilities are secured on invoices or property rather than unsecured.

How do you choose between business line of credit lenders?

Choose business line of credit lenders by how the facility is built, then by cost. Our guide to the revolving credit facility explains the product itself: a limit you draw on, repay and draw again. Before comparing prices, check five things:

  • Structure. A true revolving limit, a draw-down loan with a fixed term, or a facility that pays suppliers’ invoices for you.
  • Limit and term. Whether the limit fits your largest likely gap, and how long the facility runs before it must be renewed or repaid.
  • What secures it. A personal guarantee, your invoices, or property.
  • Fees on undrawn money. Some facilities charge a non-utilisation or commitment fee on the part you do not use.
  • Commitment. Whether the lender can reduce or withdraw the limit at review or at any time.

Which lenders publish business line of credit terms?

The table shows each lender’s line of credit or draw-down product in its own published words, from its profile in our directory of UK business lenders. Lenders are listed in alphabetical order.

How does each lender’s line of credit work?

These notes come from each lender’s profile, which records its own published terms.

  • Bizcap publishes a line of credit of up to £500,000 that lets you draw funds as needed and pay for what you use. Its page does not set out repayment, security or eligibility for this product.
  • Credit4’s Flexible Funding Facility is £15,000 to £30,000 over 3 to 12 months. You can draw, repay and redraw during the term, interest is payable fortnightly on drawn funds, all capital must be repaid by the end of the term, and guarantors are required.
  • Funding Circle’s FlexiPay line of credit is £1,000 to £250,000, with each amount you use repaid over 1, 3, 6, 9 or 12 months.
  • iwoca’s Flexi-Loan is £1,000 to £1 million over one to five years, repaid by a set amount each month, with interest charged only on what is drawn.
  • Lenkie offers an uncommitted revolving facility of up to £1 million. Lenkie pays your supplier invoices and you repay each one over 1, 3, 6, 9 or 12 months, with each repayment restoring your available balance.
  • One Stop Business Finance describes revolving credit facilities you draw and repay as required, paying interest only on what you use, but publishes no limits. It says its own-book lending always requires a personal guarantee.
  • Signature Property Finance offers a revolving credit facility of £100,000 to £1.5 million for 12 months, secured on unencumbered property at up to 50% of open market value for commercial and 70% for residential, available through professional intermediaries only.
  • TP24’s CreditLine is £250,000 to £5 million, backed by your receivables, with the limit moving as eligible receivables grow. It says you pay interest only on what you draw and that it takes no personal guarantee or floating charge.

What fees do lenders charge on drawn and undrawn balances?

A line of credit can carry three kinds of charge, and lenders mix them differently. Ask each lender for all three in writing:

  • Interest on drawn funds. Usually calculated daily on what you owe. Credit4, iwoca, One Stop and TP24 all say interest is charged only on what you draw.
  • Arrangement or renewal fees. A fee to set up the limit, sometimes charged again each time it is renewed.
  • Non-utilisation or commitment fees. A charge on the part of the limit you have not used. Not every facility has one.

A bank overdraft shows how these charges can be published. NatWest’s business overdraft page says interest is calculated daily on the end-of-day balance and charged quarterly, and its arrangement fee runs from £50 on limits of £500 and under to 1.5%, with a minimum of £150, on limits of £5,001 and above. It says the overdraft is available over 12 months. Our business overdraft guide compares overdrafts with other facilities.

Illustration: the cost of a £50,000 limit used unevenly over a year
Facility AFacility B
Average amount drawn£20,000£20,000
Interest at 12% a year on drawn funds£2,400£2,400
Arrangement fee1.5% of the limit: £750None
Non-utilisation feeNone2% a year on the undrawn £30,000: £600
Cost for the year£3,150£3,000
This is an illustration, not a quote

The rates and fees are round numbers chosen to show the arithmetic. They are not market rates or any lender’s terms. The cheaper facility depends on how much of the limit you use: draw more and Facility B gets cheaper, draw less and it gets dearer.

How do reviews work, and can a lender withdraw a line of credit?

Most lines of credit run for a set period and are then reviewed, renewed or repaid. Signature Property Finance’s facility runs for 12 months, Credit4’s for 3 to 12 months, and iwoca’s Flexi-Loan for one to five years. At review, a lender may keep the limit, change it, reprice it or decline to renew.

Some facilities can change sooner. Lenkie describes its facility as uncommitted, which generally means the lender is not obliged to fund each drawing. A receivables-backed limit such as TP24’s moves with your eligible invoices, so it can fall if your sales ledger shrinks.

Do not rely on an unused limit for a known bill

If a large payment such as a tax bill is certain, check whether the limit is committed and when it is next reviewed. A limit that can be reduced is not the same as cash in the bank.

Who can get a business line of credit?

Eligibility varies by lender and is subject to status and lender criteria. Lenders mostly look at trading history, turnover, bank statements and the credit history of the business and its directors. Personal guarantees are common on unsecured facilities: Credit4 requires guarantors, and One Stop says its own-book lending always requires one.

Regulation also depends on the borrower and amount. Under the Regulated Activities Order, credit of more than £25,000 entered into wholly or predominantly for business purposes is exempt from consumer credit regulation. A sole trader or small partnership borrowing £25,000 or less may have a regulated agreement. This is general information, not legal advice.

If your facility is meant to cover day-to-day cash needs, our guide to a working capital loan covers when a term loan may suit better.

What are the alternatives to a business line of credit?

  • A bank overdraft on your current account, for small and frequent gaps.
  • Invoice finance, if the gap comes from customers taking time to pay.
  • A short-term business loan for a single known cost.
  • Supplier credit, by negotiating longer payment terms.

Common questions

A limit agreed with a lender that you can draw on, repay and draw again during its term, usually paying interest only on what you have drawn. It suits costs that rise and fall more than a one-off purchase.
Among the lenders compared here, published limits run from £1,000 (Funding Circle and iwoca) to £5 million (TP24). What you are offered depends on your turnover, trading history and credit, and is subject to status.
Usually not interest, but some facilities charge a non-utilisation or commitment fee on the undrawn part. Ask each lender whether it has one and how it is calculated.
They work in a similar way, but an overdraft sits on your current account, while a line of credit is a separate facility, often from a lender that is not your bank. Terms, fees and reviews differ.
It depends on the agreement. A committed facility must normally be honoured until review, while an uncommitted one, such as Lenkie’s, gives the lender more freedom. Limits backed by invoices can also fall as your receivables change.
Often, for unsecured facilities. Credit4 requires guarantors and One Stop says its own-book lending always requires a personal guarantee. TP24 says it does not take one on its receivables-backed CreditLine.
