Ask a small business owner in London how 2026 has gone so far and the answer tends to arrive fast, and specific: costs are up, and not on one line of the budget but several at once. That’s not just a mood. The Federation of Small Businesses’ quarterly Small Business Index has been tracking the same pattern in its survey data — 82% of small firms report their operating costs have risen over the past 12 months, driven by a combination of raw material costs, higher overheads, and rising utility bills.
Where the pressure is actually concentrated
Wage costs are the clearest single driver. The FSB estimates, as reported by People Management, that a small firm employing nine staff on the national living wage will see its annual employment bill rise by roughly £25,850 between January 2025 and April 2026 — a 12.9% increase — with the employer National Insurance contribution portion of that bill rising by about 46% on its own. That’s not a marginal adjustment to a payroll line; for a firm of that size, it’s a material shift in what it costs to keep the same number of people employed at the same hours.
The response, unsurprisingly, shows up in staffing plans. The same FSB-sourced reporting found that 26% of small firms reduced their workforce in a recent quarter, and separate survey data points to around 35% of small firms either planning to close or scale back operations in the year ahead. Those aren’t businesses that have run out of customers — many are businesses where the cost of employing people has grown faster than the business itself.
What “adapting” actually looks like in practice
The more useful question than “are costs up” is what owners are actually doing about it, and the answers are less dramatic than mass closures — more a series of smaller, specific decisions. In practice, that tends to mean renegotiating supplier contracts before they auto-renew, delaying non-essential purchases, and — for firms with any flexibility in their footprint — reconsidering premises rather than accepting a rent increase at face value.
Premises decisions are a genuine lever in London specifically, because the cost of space varies enormously by postcode and building grade. A business paying City or West End rates for space it doesn’t fully use has more room to cut costs by relocating or downsizing than a business whose costs are mostly wages and materials. That caution is visible in the property data itself: Savills research on the Central London office market found leasing activity among smaller occupiers pulling back even as larger companies kept signing long leases on prime space, with transactions under 10,000 square feet running around 25% below their ten-year average earlier this year. Bigger tenants have kept their nerve. Smaller ones, with thinner margins for error, have been more cautious about committing to space at all.
That’s not necessarily a bad instinct. Flexible and serviced office providers have picked up demand from exactly this group of smaller occupiers, because a rolling agreement is a cheaper way to buy flexibility than a five- or ten-year lease looks right now — even before accounting for the fact that many smaller firms genuinely don’t know how much space they’ll need in two years’ time.
The businesses managing it best aren’t the ones cutting fastest
What separates firms that are managing this period well from firms that are struggling isn’t necessarily how aggressively they’ve cut costs — it’s how selectively. The instinct to cut everything uniformly when costs rise is understandable, but it tends to fall hardest on the things that actually protect revenue: marketing, product quality, and the customer relationships that keep people coming back. Owners who instead protect the handful of things that differentiate the business, while cutting harder elsewhere, tend to come out the other side of a cost squeeze in better shape than owners who cut everything by the same percentage.
That’s a pattern that shows up clearly on the high street too, where independent retailers that have kept investing in what makes them distinctive have generally outperformed those that responded to pressure by competing purely on price — a fight small firms are structurally unlikely to win against larger, better-capitalised competitors.
What this means for the year ahead
None of this points to an easy year for London’s small business owners. Cost pressure from wages, business rates, and premises is a genuine, well-documented trend, not a perception problem, and the FSB’s own data shows a meaningful share of firms responding by shrinking rather than adapting. But “some firms are closing” and “small business in London is unviable” are different claims, and the more common story in the data is narrower and more specific: firms making deliberate trade-offs about where to hold the line and where to cut, in a cost environment that isn’t reversing any time soon.
