If you run a small business in the UK and 2026 has felt like one cost increase after another, you’re not imagining it. This isn’t the usual “costs always go up a bit” grumble that business owners have made every year since the dawn of commerce. This year is genuinely different — several significant cost increases have landed at the same time, and for a lot of small employers, the combined effect is the difference between a manageable year and a genuinely difficult one.
The Federation of Small Businesses put it starkly earlier this year: 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. That’s not a typo, and it’s not an outlier business. That’s the maths for a fairly ordinary small employer.
So what’s actually driving this, and — more importantly — what can you actually do about it? This guide walks through the main pressures hitting UK small businesses right now and the practical steps that genuinely make a difference, rather than the generic “review your subscriptions” advice that doesn’t move the needle when the increases are this large.
What’s Actually Changed: The Big Three
1. Employer National Insurance — The Big One
This is, for most small businesses with employees, the single largest driver of increased costs in 2026. Two changes happened together, and their combined effect is much bigger than either looks individually.
First, the employer NI rate rose from 13.8% to 15%. On its own, a 1.2 percentage point increase doesn’t sound dramatic.
Second — and this is the part that really bites — the threshold at which employers start paying NI on an employee’s earnings dropped from £9,100 a year to £5,000. That’s an extra £4,100 of each employee’s salary that now falls into the taxable band. Apply 15% to that additional £4,100, and you’re looking at roughly £615 in additional NI per employee, before you even account for the rate increase on the rest of their salary.
Put both changes together, and the cost of employing someone on or near minimum wage has gone up by somewhere in the region of £1,500–£2,400 per year, depending on their hours and exact pay. For a business with eight or nine staff, that compounds into the kind of five-figure annual increase the FSB highlighted.
The good news — and it’s a genuine one: the Employment Allowance, which lets eligible employers offset some of their employer NI bill, increased to £10,500 for 2026/27, and the previous £100,000 NI liability cap that restricted who could claim it has been completely removed. This means businesses of almost any size can now claim the full allowance, where previously larger SMEs were excluded.
For a small business with five employees earning £25,000 each, the total employer NI bill might be around £15,000 — but after applying the £10,500 Employment Allowance, that drops to roughly £4,500. If you haven’t checked whether you’re claiming this allowance, or whether your payroll software is applying it correctly, this is the single most important thing to check this month. It’s the difference between absorbing the NI increase and being hit by it in full.
2. National Living Wage — Up Again, With Age Bands Disappearing
From 1 April 2026, the National Living Wage rose to £12.71 per hour for workers aged 21 and over. Workers aged 18-20 saw a sharper jump to £10.85 — an 8.5% increase — as part of a deliberate move to narrow the gap between age bands. 16-17 year olds and apprentices moved to £8.00 per hour.
The narrowing of age bands matters more than it might first appear. Historically, hiring younger workers came with a built-in cost advantage. As that gap closes, the financial incentive to hire less experienced staff at a lower rate diminishes — which has knock-on effects for businesses that have traditionally relied on a pipeline of younger, lower-cost workers, particularly in hospitality and retail.
There’s also a less obvious effect worth planning for: wage compression. When the wage floor rises, staff who are already paid slightly above minimum wage — supervisors, more experienced team members — often expect their pay to rise proportionally too, to maintain the gap. If you only budget for the statutory increase at the bottom of your pay structure, you may find yourself facing additional pressure further up it as well.
3. Business Energy Costs — Still Elevated, Still Worth Fighting
Business electricity prices remain roughly 60-75% higher than pre-2021 levels. Unlike domestic energy, which is protected by the Ofgem price cap, business energy operates in a fully liberalised market — your supplier can set whatever price they like, and if you don’t actively manage your contract, you can end up rolled onto a deemed or out-of-contract rate that’s 30-80% more expensive than a negotiated tariff.
This is genuinely one of the areas where small businesses lose the most money through simple inertia. A typical small business might pay somewhere between £1,000 and £2,500 a year for electricity — but the gap between a well-negotiated fixed contract and a deemed rate after a missed renewal window can be enormous.
What You Can Actually Do About It
Here’s where this gets practical. Some of these are quick wins you can action this week. Others are bigger structural decisions that take more thought — but given the scale of the cost increases hitting businesses this year, “doing nothing” isn’t really a neutral choice anymore.
Claim — and Maximise — Your Employment Allowance
If you’re not already claiming the Employment Allowance, this should be priority one. With the £100,000 cap removed and the allowance increased to £10,500, eligibility has widened significantly for 2026/27. Speak to your accountant or check your payroll software settings directly — this is the kind of thing that’s easy to miss if your system wasn’t updated for the latest rules, and it’s worth checking even if you believe you’re already claiming it correctly.
Model Your Actual 2026/27 Payroll Costs — Properly
A lot of businesses are still budgeting payroll based on gross salary alone, without factoring in the full cost of the NI threshold change. The total cost of employing someone now includes gross salary, the increased employer NI (after the Employment Allowance), and pension contributions — and the gap between gross salary and total cost has widened considerably this year.
Run the actual numbers for your current team, including any planned pay reviews from the wage floor increase. For many small businesses, this single exercise — actually seeing the real total cost per employee for 2026/27 versus 2025/26 — is the moment the scale of the change becomes clear, and it’s essential for setting prices, planning hiring, and managing cash flow through the year.
Review Your Energy Contract — Before You’re Forced To
If your business energy contract is coming up for renewal in the next few months, don’t let the renewal window pass without action. Suppliers routinely price renewal quotes higher than what’s available on the open market, banking on the fact that switching feels like effort that gets deprioritised.
A few specific things worth checking:
VAT rate. Business electricity is charged at 20% VAT by default, but drops to 5% if your business uses under roughly 12,000 kWh of electricity a year (about 33 kWh/day), or under roughly 53,000 kWh of gas a year. Many small businesses — particularly those in small premises like shops, salons, or offices — qualify for this reduced rate and aren’t claiming it. Getting this wrong means overpaying by a meaningful margin on every single bill, regardless of how good your unit rate is.
Climate Change Levy (CCL) relief. This is a separate environmental charge added to most business energy bills. Certain businesses qualify for full or partial relief — worth checking if you haven’t reviewed this recently.
Compare before you renew, every time. Switching or renegotiating routinely cuts 15-35% off the unit rate compared to a standard renewal quote. Even if you ultimately stay with your existing supplier, having a competing quote in hand gives you genuine leverage to negotiate.
Look at Your Pricing — Honestly
This is the conversation a lot of small business owners avoid, often because it feels uncomfortable to put prices up when customers are also feeling the squeeze. But here’s the reality: if your costs have risen by 10-13% and your prices haven’t moved at all, your margin has shrunk by roughly that amount — and margins that were already tight before this year’s increases don’t have much room left to absorb that.
This doesn’t mean a blanket price increase across everything. It might mean reviewing your lowest-margin products or services specifically, building cost increases into contracts that are up for renewal, or being more disciplined about discounting than you have been previously. The businesses that come through a year like this in the best shape tend to be the ones that addressed pricing proactively in spring, rather than reactively in autumn when cash flow has already become a problem.
Reassess Your Staffing Structure — Carefully
With the cost of employing staff at minimum wage having risen so sharply, and the age-band gap narrowing, it’s worth genuinely reassessing how your team is structured — not necessarily to cut headcount, but to think about whether the roles, hours, and shift patterns you have still make sense.
For service-sector businesses in particular, the “ceiling effect” is real: if the cost of staffing a quiet weekday shift now exceeds what that shift generates in revenue, something has to change — whether that’s adjusted opening hours, different staffing levels at different times, or a genuine look at which shifts are actually profitable. This is a difficult conversation, but ignoring it doesn’t make the underlying maths go away.

On a more positive note, the apprenticeship rate (£8.00/hour for eligible apprentices) remains significantly below the adult rate, and structured apprenticeship programmes can be a genuinely useful way to bring in new talent at a more sustainable cost while providing a real training pathway — worth exploring if you have roles that suit it.
Build a Cash Flow Buffer for April and May Specifically
If your payroll software wasn’t updated correctly for the new NI thresholds and minimum wage rates from 1 April, the first payroll run of the new tax year can produce a genuinely unpleasant surprise. Several accountants have specifically flagged that most payroll mistakes around the new tax year aren’t caused by complicated tax law — they’re caused by old rates left in software, rushed approvals, and timing issues.
If you haven’t already done this for the current tax year, build in a deliberate cash flow check for your April and May payroll runs specifically: confirm your software is using 2026/27 rates, confirm wage rate updates were applied from 1 April, and have a contingency buffer in place in case the actual payroll cost comes in higher than budgeted. Catching a discrepancy in April is a manageable adjustment. Discovering it in October, after six months of underbudgeted payroll, is a much bigger problem.
Talk to Your Accountant About Structure — Not Just Compliance
A lot of small business owners only really speak to their accountant at year-end, for compliance purposes. Given the scale of changes this year, it’s worth a proactive conversation specifically about whether your current business structure — sole trader, limited company, how you draw income — still makes sense given the new NI and wage landscape. This isn’t about aggressive tax planning; it’s about making sure decisions made in a previous, different cost environment are still the right ones now.
The Things That Don’t Help (Even Though They Sound Like They Should)
A quick word on a few approaches that often get suggested but rarely move the needle for genuinely cost-pressured small businesses:
Generic subscription audits. Reviewing your software subscriptions is sensible housekeeping, but for most small businesses the numbers involved — typically a few hundred pounds a year — are tiny compared to a five-figure increase in payroll costs. Do it, but don’t expect it to solve the actual problem.
Switching banks for a one-off bonus. As covered elsewhere on this site, switching bonuses are genuinely useful for individuals — but for a business facing structural cost increases, a £200-£250 bonus is a rounding error, not a strategy.
Waiting for things to improve. Some of the cost pressures businesses are facing — energy prices in particular — are expected to gradually stabilise over the next couple of years as the market settles further from the 2022 crisis peaks. But “things might get better eventually” isn’t a cash flow plan for the next twelve months. The businesses that come through this year well are the ones that adjusted to the costs as they currently stand, not the ones that waited for them to change.
Conclusion
The scale of cost increases hitting UK small businesses in 2026 is real, well-documented, and not something that can be fully offset by cutting a few subscriptions or switching energy supplier alone — though both of those things genuinely help.
The biggest single lever most small businesses have right now is making sure they’re claiming the full, expanded Employment Allowance — a change specifically designed to help smaller employers absorb the NI increase, and one that’s easy to miss if your payroll setup wasn’t updated. Beyond that, the combination of properly modelling your real 2026/27 costs, reviewing energy contracts before renewal deadlines pass, and having an honest look at pricing are the things that actually change the trajectory of the year.
None of this is comfortable. But businesses that engage with these numbers directly — rather than hoping the gap closes itself — are in a fundamentally stronger position heading into the rest of 2026 than those that don’t.
