How to Restructure UK Business Debt: A Practical Guide

UK businesses that have accumulated multiple loans, HP agreements, or high-rate facilities often find that their combined monthly repayments are straining cash flow. Debt restructuring, consolidating or refinancing existing obligations at better terms, can free up significant monthly cash and reduce the total interest cost over time. This guide explains how to approach it.
When to consider debt restructuring
Restructuring makes sense when: the combined monthly repayments across multiple facilities are too high relative to cash flow, the interest rates on existing facilities are materially above current market rates, you have multiple short-term loans that would be cheaper as a single longer-term facility, or the complexity of managing multiple facilities is creating administrative burden and risk of missed payments.
It is less appropriate if the existing facilities have significant early repayment charges that would exceed the interest saving from restructuring, if the business has deteriorating financial performance that would make new facilities more expensive than the ones being replaced, or if the restructuring would extend debt tenure so far that total interest over the new term exceeds total interest remaining on existing facilities.
Calculating whether restructuring saves money
For each existing facility, obtain a settlement figure (the amount required to repay it today). Sum all settlement figures to get the total consolidation amount. Compare the total monthly repayment on the new facility against the combined monthly repayments on all existing facilities. Multiply the monthly saving by the new loan term to estimate the gross cash flow benefit.
Then subtract the total interest on the new facility from the total remaining interest on all existing facilities (if they ran to maturity). If the new total interest is lower, restructuring saves money on a total cost basis. If it is higher but monthly payments are lower, you are paying more overall but improving cash flow, which may still be worth it if the cash flow relief unlocks business growth.
"Debt restructuring is not a sign of financial difficulty. For well-run businesses that have accumulated facilities over time, it is a routine financial management exercise that often produces significant savings."

Secured consolidation vs unsecured consolidation
If the business has commercial property with equity, a secured consolidation loan can refinance high-rate unsecured debt at property-secured rates, producing a much larger rate saving than consolidating into a lower-rate unsecured loan. The trade-off is that business property is put at risk. For businesses with strong property equity and manageable trading risk, this is often the most cost-effective restructuring route.
Unsecured consolidation loans are available for businesses that have demonstrated consistent trading and want to simplify multiple high-rate obligations into one lower-rate facility. The maximum amount accessible unsecured is typically 500,000 pounds, and the rate offered will depend on the business profile and the total debt being consolidated.
Dealing with early repayment charges
Most commercial loan and HP agreements have some form of early repayment charge. Before proceeding with restructuring, obtain settlement figures from all existing lenders that include any ERCs. Factor these into your calculation: if three existing facilities have combined ERCs of 15,000 pounds, this must be recovered through the interest saving on the new facility before restructuring generates a net benefit.
Some ERCs decline over time (for example, a charge of 3 months' interest reducing to 1 month's interest in the final year). For facilities with declining ERCs that are close to the maturity or the lower-charge window, waiting a few months before restructuring can save thousands in exit costs without meaningfully delaying the benefit of the new lower-rate facility.
