The employer National Insurance rise is quietly reshaping which UK salons are worth buying

The employer National Insurance change that took effect in April 2025 was not a headline in the salon world, but it changed the maths under every chair you employ. Here is what it actually does to your margin, your hiring choices, and, less obviously, what your salon is worth to a buyer.

What actually changed

From 6 April 2025 two things moved at once. Employer (secondary) National Insurance rose from 13.8% to 15%, and the threshold where you start paying it dropped from £9,100 to £5,000 of an employee's pay. The Employment Allowance, which offsets some of this for smaller employers, was raised to £10,500, which softens the blow for the smallest teams but runs out fast once you have a few full-time stylists.

The net effect: employing a stylist costs more than it did, and the increase bites hardest on lower-paid and part-time staff, because you now pay employer NI from a much lower point on their wage.

What it does to a salon's margin

Labour is already the largest cost line in most salons. A rise in the employer cost of every employed hour compresses a margin that was rarely generous to begin with. If you have not repriced since early 2025, you have quietly absorbed the increase out of your own profit.

Two honest numbers to run on your own books: your total employed wage bill, and what a 1.2 point NI rise plus the lower threshold adds to it. For a salon with several full-time stylists that is not a rounding error, it is a real chunk of annual profit that used to be yours.

The hiring decision it forces

The change widens the gap between employing a stylist and renting a chair to a self-employed one. That is not automatically a reason to switch, chair rental changes your control, your brand consistency, and crucially how a buyer values the business, but it is now a decision with a bigger number attached, and pretending otherwise costs you money every month.

The part almost no one connects: your exit value

Here is the uncomfortable link. A buyer values a salon on the profit a new owner can keep, its Seller's Discretionary Earnings, times a multiple. A permanent rise in labour cost lowers that profit unless you have repriced or restructured to offset it. So this tax change did not just take a slice of this year's income, it quietly marked down what your salon is worth, for every owner who did nothing.

The owners who come out ahead are the ones who treated it as a trigger to reprice, tighten rota to real demand, and lift the share of revenue that is not pure labour (retail, memberships, higher-value services). Those moves rebuild the margin and, because they make the profit more durable and less owner-dependent, they lift the multiple too.
