From 6 April 2025, the employer (Class 1 secondary) National Insurance rate rose from 13.8% to 15%. That's a 1.2 percentage-point uplift – roughly a 9% increase per pound of NI-able pay.
Two other policy shifts amplified the impact:
- The secondary threshold fell to £5,000 (down from £9,100), meaning NI now kicks in much earlier.
- The Employment Allowance for eligible employers doubled to £10,500. Helpful – but modest relief against large wage bills.
For labour-intensive businesses, this change is not 6 marginal – it's material.
Real-World Signals
The National Insurance rise isn't just theory the effects are already visible in boardrooms, trading updates, and market forecasts:
- Next plc: The FTSE 100 retailer has openly f lagged an additional £67m in wage and NI costs for 2025/26. To manage the pressure, they've signalled a ~1% price increase but are also leaning heavily on efficiency programs to avoid losing competitiveness. This illustrates the balancing act between protecting margins and holding customer demand.
- Retail sector more broadly: According to the British Retail Consortium (BRC), the NIC change alone adds £2.3bn+ to the annual cost base of UK retailers. And that's before factoring in the higher National Living Wage and other cost headwinds. For an industry already operating on single-digit margins, this scale of additional cost is a direct threat to profitability and store viability.
- Halfords: The automotive and cycling services group guided to ~£23m of incremental FY26 labour costs directly from the Budget changes.
At the same time, it reported a £30m statutory pre-tax loss in FY25 – driven mainly by a non-cash impairment – but the result underscores how rising staff costs can quickly tip thin-margin businesses into loss-making territory.
These examples show a clear pattern: employers are being forced into difficult trade-offs.
- Pause recruitment? You cap capacity and restrict growth.
- Raise prices? You risk losing competitiveness in a fragile consumer market.
- Hold prices on fixed contracts? Margins erode until you can reprice.
The pressure is real. But it doesn't have to be terminal. There is another route.
