The manager of a forty-bed care home in Plymouth ran the April 2025 payroll and then ran it again, because the employer's National Insurance line did not look like a rounding difference. Nothing about the home had changed. The same residents were in the same rooms, the same carers were on the same rota, and the rota was already as thin as the regulator would tolerate.
Two thirds of the beds were funded by the city council at a rate agreed the previous winter for the year ahead. That rate was not going to move until the following April, whatever the payroll did.
A great many labour-intensive businesses were in the same position that month. The arithmetic is not complicated and the consequences were not evenly spread.
Two changes landed in the same payroll
From April 2025 the employer's rate of secondary Class 1 National Insurance rose from 13.8 per cent to 15 per cent. At the same time the secondary threshold, the point at which an employer starts paying anything at all on an employee's earnings, fell from £9,100 a year to £5,000.
In the same month the National Living Wage for workers aged twenty-one and over rose to £12.21 an hour, from £11.44, and the rate for eighteen to twenty year olds rose to £10.00.
Put a full-time carer on the minimum, thirty-seven and a half hours a week, through both changes. The pay goes to roughly £23,810 a year, from roughly £22,310. The employer's National Insurance on that pay goes to about £2,820, from about £1,820. The total cost of employing that person rises from around £24,130 to around £26,630, an increase of roughly £2,500, or a little over ten per cent, for exactly the same shifts.
There was an offset. The Employment Allowance, which reduces an eligible employer's National Insurance bill, rose from £5,000 to £10,500 and the restriction that barred employers with large previous-year liabilities was removed. It is a fixed sum per business, so it matters enormously to a firm with six employees and much less to one with sixty. Whether a provider delivering mostly publicly funded care can claim it turns on the rule about work of a public nature, which is a question for an accountant rather than an assumption.
The threshold mattered more than the rate
Most of the commentary concentrated on the move from 13.8 to 15 per cent. For a business built on part-time staff, the threshold was the larger event.
At £9,100 a year, an employee working modest hours generated no employer National Insurance at all. At £5,000 they generate it on almost everything they earn. Social care runs on part-time contracts, bank staff, weekend cover and people working around school hours, and a home with a long tail of small contracts saw a step change in cost on staff who had previously cost nothing beyond their wages.
The same applied to the shape of the workforce in hospitality, retail, cleaning, childcare and any other trade where the rota is built out of short shifts. A business with the same wage bill delivered through twice as many people pays more employer National Insurance than one delivering it through half as many, and from April 2025 that difference got wider.
There is a further compression. When the statutory minimum rises by more than general pay settlements, the gap between a new starter and a senior carer or a shift leader narrows. Either the differential is restored, which costs more than the headline change, or it is not, and the experienced staff notice.
Most of the revenue was fixed the year before
A care home's income divides into two very different halves. Council-funded residents are paid for at a rate the local authority sets, usually agreed for the financial year and published in advance. Self-funding residents pay a price the home sets, and it can change it.
The increase was announced in the Budget at the end of October 2024 and took effect the following April. That sounds like ample notice, and for most employers it was. For providers of publicly commissioned services it was not, because councils were setting their fee rates for 2025 to 2026 in exactly that window, under their own financial pressures, and a fee rate once set does not reopen mid-year because a supplier's costs rose.
Local authorities have a duty under the Care Act 2014 to promote an efficient and effective market in care services, and that duty is not a price mechanism. It does not entitle a home to a particular rate, or give it a mid-year review.
There was also a difference in treatment. Funding was made available to public sector employers to meet the cost of the increase. Independent providers delivering services commissioned by the public sector were not in that category, and absorbed it through their own accounts.
So the home with a high proportion of self-funders could recover part of the increase within weeks by repricing, and the home whose beds were mostly council-funded could not. Two homes of identical quality, in the same city, faced completely different Aprils.
The levers are staffing, mix and occupancy, and one of them is watched
Occupancy is the first and best lever, because the cost of an empty bed is nearly the cost of a full one. Moving from the high eighties to the high nineties changes the result more than any cost exercise, and it depends on reputation, referrals and the inspection rating.
Mix is the second. Taking more self-funding residents, or more of the higher-dependency placements that attract nursing rates, changes the average income per bed. It takes months, it depends on the local market, and it is not a lever you can pull in April.
Agency spend is the third and the most controllable. Agency hours cost far more than a substantive post and they rise when the home is short-staffed, so the way out of a cost problem often runs through a recruitment problem.
Cutting the rota is the fourth, and it is the one that ends badly. Providers in England are registered with and inspected by the Care Quality Commission, and the regulations require enough suitably qualified and competent staff to be deployed to meet residents' needs. Staffing below that level does not save money, it buys an inspection, and the rating that follows is what the next family reads before they choose.
Where this shows up in the game
The April Bill starts a care home in Plymouth in April 2025 and runs for eighteen months. It is marked Hard, and you begin carrying borrowing that somebody else agreed to before you arrived, which narrows the room to absorb anything.
The payroll cost rises in month one on the real tax tables, because the engine already carries them and applies them on their real dates. Council-funded fees are two thirds of your revenue and are fixed until the following April. Self-funded residents can be charged more, which shifts the mix over time if you can attract them. Staffing below the level the regulator expects triggers an inspection, and the inspection does what inspections do.
You are scored on still employing thirty-four people at the end of the eighteen months, with the inspection rating reported in the epilogue, which is the game's way of saying that a home which cuts its way to survival has not really survived. The page for The April Bill sets out the starting figures. The seed is fixed at 600021, so everybody attempting it meets the same city, the same council and the same market, and the scores are comparable. It runs under ironman rules: one save, and what happens happens.
