The Skillset Shelf Life
Genuine question: what's the shelf life of a finance job spec right now?
Six months ago, a client needed someone for month-end close. Manual reconciliations, posting journals, producing management accounts. Standard finance work.
Now they need someone who can automate month-end so they can focus on forecasting and scenario planning instead.
The role hasn't disappeared. It's completely different.
When Finance Job Specs Have Expiry Dates
This isn't unique to finance, but finance feels it particularly acutely. The skills you need today might be outdated in twelve months. The tools your finance team uses now might be replaced by something more efficient next quarter. The processes you've perfected might become redundant when automation catches up.
And that creates a problem when you're making permanent finance hiring decisions.
Hiring permanent feels risky when you don't know what finance skills you'll need in a year. And that risk just got more expensive.
The October 2024 UK Budget Made Everything Worse
The numbers are stark. From April 2025:
Employer National Insurance contributions increased from 13.8% to 15%
The threshold at which employers start paying NI dropped from £9,100 to £5,000
National Living Wage increased to £12.21 per hour for those aged 21 and over
Under the new rules, a business now pays £865.80 more in National Insurance on an employee earning £30,000, boosting the total cost from £32,884.20 to £33,750.
That £30k hire? It now costs closer to £38k when you factor in employer NI, pension contributions, and other employment costs. And that's before considering recruitment costs, onboarding time, equipment, and software licences.
The government increased the Employment Allowance from £5,000 to £10,500 to help smaller businesses, which means 865,000 businesses will pay no NICs at all, and more than half of employers with NIC liabilities will either see no change or will gain overall. But if you're beyond that threshold, or planning to grow beyond it, the cost increase is real.
Getting a permanent hire wrong has always been expensive. Now it's more expensive, and the risk of getting it wrong feels higher because the skillset you need keeps shifting.
Automation Isn't Coming, It's Here
Between 25% and 30% of UK roles are expected to be significantly affected by automation by 2030, with up to 30% of jobs automatable by the mid-2030s.
Notice the language there. "Affected by" not "replaced by." Most jobs won't disappear, they'll change. The person doing month-end close doesn't become redundant, they become someone who manages automated processes and focuses on analysis instead.
But that shift requires different skills. Skills your current team might not have. Skills that might not even exist yet in a teachable form.
Between 400 million and 800 million individuals globally could be displaced by automation and need to find new jobs by 2030, with 75 million to 375 million potentially needing to switch occupational categories and learn new skills.
The UK isn't immune to this. We're in the middle of it.
Your Finance Function Is Already Maxed Out
Here's the other problem. The finance capacity you have is absorbed in day-to-day delivery. Month-end close, VAT returns, payroll processing, chasing late payments. There's no headspace for process improvement or working out what automation even means for your specific finance workflows.
According to late 2025 UK business surveys, more than 60% of small businesses are paid late by bigger companies, costing UK SMEs an average of £22,000 per year in delayed working capital. When your finance team is constantly chasing payments and firefighting cash flow issues, nobody has capacity to figure out how to prevent the fires from starting.
You could hire someone in finance specifically to drive efficiency and automation. But what happens when they've automated everything? Do you have enough ongoing finance work to justify keeping them? And what if the tools change and their specific expertise becomes outdated?
This is the dilemma: rising costs, uncertain skill requirements in finance functions, and maxed-out finance capacity.
The Fractional Finance Model Makes Sense Here
The fractional economy has exploded precisely because of these challenges. Fractional CFO demand surged 103% in 2025-2026, with the number of professionals referencing fractional CFO/C-suite leadership roles growing from just 2,000 in 2022 to 110,000 by late 2024.
That's not gradual adoption, that's a fundamental shift.
By 2026, over 40% of growth-stage companies are expected to use fractional leadership models in some capacity, particularly for finance functions. In early 2025, approximately 5% of UK employees were working in interim or non-traditional roles, with UK startups doubling their fractional finance hires since 2022.
Why? Because businesses need flexibility in their finance functions specifically.
What fractional finance actually means
Fractional finance isn't about hiring someone part-time. It's about accessing the right financial expertise at the right level for the right duration, without committing to a permanent headcount increase.
For finance specifically, it means:
Strategic finance leadership when you need it – FD-level thinking for growth decisions, funding preparation, or major financial projects, without paying £100k+ for a full-time Finance Director.
Finance execution capacity when you're stretched – Extra hands for year-end close, system migrations, backlog cleanup, or audit preparation, scaled to the financial work that needs doing.
Specialist finance skills when gaps appear – Automation expertise, cash flow modelling, financial due diligence, or fundraising support, brought in for specific financial challenges without permanent overhead.
Flexibility as financial needs change – Scale up finance support when you're hiring, scaling, or fundraising. Scale down during quieter periods or once the immediate financial challenge is solved.
The key difference? You're not betting on what finance skills you'll need in 18 months. You're accessing financial expertise that adapts as your needs evolve.
The Finance Skills That Keep Changing
In finance alone, the last few years have seen massive shifts:
2020-2021: Finance teams suddenly needed people who understood government support schemes (furlough, bounce back loans, grants) and could model scenarios for businesses operating in extreme uncertainty.
2022-2023: Rising interest rates and inflation meant finance functions needed people who could re-forecast, optimize cash flow through rapid cost increases, and help businesses manage working capital as payment terms stretched.
2023-2024: With 90% of startups failing and 29% running out of cash, finance teams needed people who could provide early warning systems, model different scenarios, and help founders understand which parts of the business were profitable.
2024-2025: The October 2024 UK Budget changes (NI rising to 15%, threshold dropping to £5,000) meant finance teams needed people who could model employment cost impacts and help optimize the cost base.
2025-2026: With 25% of businesses now using AI technology (up from 10% in late 2023) and fractional CFO demand surging 103%, finance functions need people who can implement AI-driven financial tools, automate processes, and focus on strategic analysis rather than manual processing.
The skillsets required in finance have changed every 12-18 months. If you'd hired someone permanent with the perfect finance skillset for 2020, they'd be wrong for 2026 unless they'd continuously upskilled.
That's the shelf life problem.
How Fractional Finance Teams Stay Current
The fractional finance model solves this in a way permanent hiring can't.
Constant upskilling – Fractional finance professionals work across multiple clients, which means they're exposed to more financial challenges, more tools, and more solutions than someone working in a single business. They learn faster because they're seeing more.
Shared learning – When one client implements a new financial automation tool successfully, that knowledge gets applied to other clients. Best practices in finance spread quickly across a fractional team's portfolio.
Flexible skill mix – Need automation expertise for your finance systems? Bring in someone who does that. Need cash flow forecasting? Different person. Need fundraising support? Another again. You're not locked into one person's financial skillset.
Tomorrow's finance skills, not just today's – Because fractional finance professionals are continuously working on the newest financial challenges across different businesses, they're building tomorrow's skillset whilst others are still catching up.
UK SMEs report savings of 40 to 60% in executive-level labour costs by hiring fractional finance executives compared to full-time counterparts, with companies reporting a 340% return on investment within six months. But the bigger advantage is accessing evolving financial expertise without permanent commitment.
When Permanent Finance Hires Still Make Sense
This isn't an argument that permanent finance hiring is dead. It's not.
You absolutely should hire permanent for finance roles when:
Core finance functions that won't change – If someone's job is fundamentally stable and will remain valuable regardless of technology shifts, permanent makes sense. In finance, that's often bookkeeping (someone still needs to process transactions, even if the tools improve).
Business-critical financial knowledge – Roles where deep institutional knowledge of your specific financial setup, customers, products, and history is the main value. Understanding your unique financial complexities takes time to build and is hard to replace.
Team building in finance – When you're at a stage where building a cohesive finance team matters more than pure flexibility. Culture in finance teams is built by people who stick around.
Long-term finance capacity needs – If you have enough finance work to justify someone full-time for the foreseeable future, and their financial skillset is durable, permanent might be more cost-effective than fractional in the long run.
But for specialized financial skills, strategic finance oversight, or anything where you're uncertain about long-term financial need? Fractional gives you an option that didn't used to exist.
The Finance Hiring Decision Framework
When you're considering a finance hire, ask these questions:
Is this finance skillset likely to change in the next 18 months? If yes, fractional might give you more flexibility.
Do I have enough ongoing finance work to justify full-time? If not, you're paying for unused financial capacity.
Am I hiring for a specific financial project or ongoing financial need? Project-based financial work suits fractional. Ongoing baseline finance work suits permanent.
Can I afford to get this finance hire wrong? With the increased costs from April 2025, the financial impact of a bad finance hire is higher.
Do I need this person to build institutional financial knowledge? Some finance roles benefit from continuity. Others benefit from fresh perspective.
There's no single right answer. But there are more options now for finance functions than "permanent or nothing."
What This Looks Like in Finance Practice
Here's how this plays out with actual businesses:
Scenario 1: Growing retail business
They have a bookkeeper (permanent, 3 days per week) who handles day-to-day transactions. They bring in fractional FD support (2 days per month) for strategic financial planning, cash flow forecasting, and board reporting. During busy financial periods (year-end, funding rounds), they scale up. During quiet periods, they scale down.
Total cost: Significantly less than a full-time Finance Director, with flexibility to adapt as they grow.
Scenario 2: Tech startup post-funding
They need to professionalize their finance function quickly. They bring in a fractional finance team for 6 months: FD to set financial strategy and build infrastructure, analyst to implement systems and create financial reporting, bookkeeper to clean up historical mess.
Once everything's properly set up, they can either keep the fractional finance team scaled down for ongoing support, or hire permanent finance staff now they know exactly what they need.
Scenario 3: Established consultancy
They have a permanent Finance Manager who handles most things. They bring in fractional finance support for specific projects: automating invoicing, implementing new forecasting tools, supporting due diligence when they're considering an acquisition.
They're not replacing their Finance Manager. They're giving them access to specialist financial skills when needed without permanent overhead.
The Unstable World We're Working In
In late December 2025, approximately 25% of businesses reported using some form of AI technology, up 15 percentage points since late September 2023. For businesses with 250+ employees, that proportion was 44%. Meanwhile, 15% of businesses are planning to adopt AI within the next three months.
More than 60% of small businesses are being paid late by bigger companies, costing UK SMEs an average of £22,000 per year in delayed working capital. Falling demand affects 18% of businesses, with taxation concerns affecting another 15%.
Interest rates have been cut from 5.25% in August 2024 to 3.75% in December 2025, but economic uncertainty persists.
This isn't a stable environment for making long-term financial hiring commitments. It's an environment that rewards flexibility in finance functions.
The finance skillset shelf life problem isn't going away. If anything, it's accelerating. AI and automation will continue to change what finance roles look like. Economic uncertainty will continue to affect how much financial capacity businesses can afford. Employment costs will continue to shift with government policy.
In that context, having options for your finance function matters.
Where Sure Thing Fits
This is why we built Sure Thing as a finance team, not a solo FD.
You get FD-level financial strategy (that's me) for the big decisions and board reporting. You get analyst support for financial modelling, forecasting, and getting finance systems actually working. You get bookkeeping capacity when you need to catch up on backlog or handle busy financial periods.
You scale your finance function up and down as your business requires. You're accessing finance professionals who are constantly upskilling, sharing learnings across clients, and bringing tomorrow's financial skillset, not just today's.
It's a flexible finance model for an unstable, unpredictable world.
If you're looking at your finance function and wondering whether permanent hires still make sense for every finance role, let's talk about what flexible actually looks like.
