Measures set out in the Autumn Statement are now taking effect. Minimum wages and business rates are higher. For many retailers and hospitality operators, these changes are landing at the same time.
These reflect a significant shift in the baseline cost of trading, at a time when consumers are feeling their own squeeze and are cautious about price increases.
Payments sit directly in this equation; as prices rise to absorb higher costs, payment fees rise with them because they scale with transaction value. Cost pressure moves through the business, and payments budgets increase automatically.
This has a direct impact on the profitability of each transaction.
Labour costs move the baseline
When the National Minimum Wage was introduced in 1999, the adult rate was £3.60 an hour. From April 2026, the National Living Wage is £12.71 for workers aged 21 and over.
That is an increase of just over 250%.
This change reflects long-term policy decisions rather than short-term economic cycles, therefore creating a higher baseline cost of simply doing business. Retail and hospitality are sectors that rely heavily on hourly staff and face some of the largest cost increases.
Labour Costs and Inflation
Using CPI data from the Office for National Statistics and the Bank of England inflation methodology, £3.60 in 1999 equates to roughly £9.00 in 2026 prices. As of April 2026, the legal minimum is £12.71.
That difference represents a meaningful increase in real labour costs over the period.
| Measure | Amount |
| 1999 wage (nominal) | £3.60 |
| 1999 wage in 2026 prices | ~£9.00 |
| Actual 2026 NLW | £12.71 |
Business Rate Impact
Business rates reinforce the same cost dynamics as they are linked to property valuations and multipliers rather than trading performance. When demand weakens or margins compress, rates do not move with them.
As of April 2026, many of the COVID-related reliefs are expiring or being restructured, with hospitality and retail again carrying a larger proportional burden than other businesses.
In day-to-day operations, business rates are a cost that must be absorbed rather than managed dynamically.
The Suppression of Margin
The combination of labour and rates costs increasing, margin is taking a hit.
Over the past two decades, average retail operating margins have contracted from about 5-6% to roughly 2-3%. Hospitality margins show a similar pattern, moving from high single digits to mid-single digits, and can be even lower for independents operators.
This is not necessarily a reflection of the efficiency or performance of the businesses themselves; as core costs have increased faster than revenue, profitability has been adjusted downwards.
Payments evolved under different conditions
The economics of the payments supply chain has developed differently to that of the merchant.
Card networks, such as Visa and Mastercard operate asset-light models. Pricing scales with transaction value. Operating costs are concentrated in technology infrastructure, fraud prevention, compliance, and network resilience rather than physical assets or large hourly workforces.
Public filings show operating margins for the major card networks in the 60-65% range. Acquirers and processors work on lower margins, but still benefit from volume growth and scale efficiencies.
These outcomes reflect structural differences rather than commercial behaviour. Payment providers profitability is determined by volume, whereas merchants are exposed to labour, property and discretionary demand.
Payment costs increased and were passed through
Over the same period of National Minimum Wage increases, payments costs have risen.
Networks and processors have consistently introduced a series of fee changes covering scheme fees, processing, cross-border transactions, fraud, compliance requirements.
Providers have consistently attributed these increases to higher fraud volumes, tighter regulation, and the need for continued investment in infrastructure and security.
For merchants, the effect has been direct. In most cases, increases have been passed through either explicitly or through adjustments within existing pricing structures. With the prevalence of card acceptance, there is limited scope to avoid this expose.
Payments costs have therefore increased alongside wages, rates, and energy. All adding to the overall cost base, rather than offsetting it.
Percentage pricing amplifies price changes
Whether a merchant is on Interchange+, Interchange++, blended or flat rates, the majority of fees scale with transaction value. When prices rise to cover higher operating costs, payment fees increase at the same rate.
The profile of the transaction itself does not change; it’s the same item. The payment cost increases because the value of the transaction increases.
Over time, this compounds the pressure on margins as pricing adjustments feed through the payments layer automatically.
Where Opt‑ic comes in
Most merchants have already scrutinised headcount, adjusted opening hours, reviewed the viability of certain locations, nudged pricing where the market allows.
What remains is how money flows through the payments supply chain.
Every sale now carries more cost than it used to. Labour, rates and operating overheads are largely fixed, and payment costs scale automatically as prices move up. That leaves fewer places where profit can be improved without trading off volume, experience, or growth.
Opt‑ic works with merchants at the transaction level; how do customers, their payments choices and your payments supply chain interact?
That might mean improving acceptance so fewer sales fail, choosing payment types that cost less for the same basket, reducing friction that suppresses conversion,
or ensuring higher‑value transactions aren’t being processed in the most expensive way by default.
How can you make transactions work harder in a system where margins are already doing too much of the work?
For businesses operating in a tighter cost environment, that difference matters.
