Every charity has its rhythms. There is the autumn flurry of grant applications, the warm rush of Christmas appeals and the steady tick of regular giving that keeps the lights on in between. And then there is a season many UK charities dread, one that quietly drains the bank balance while everyone is looking the other way. If your organisation has ever reached late August and felt an unwelcome jolt of panic about cash flow, you are far from alone. The “summer fundraising gap” is one of the most predictable challenges in the sector, yet it catches well-run charities out year after year. And it lands at an already difficult moment for charity finances.
A sector already under financial pressure
The summer dip does not happen in a vacuum. It compounds the pressures the whole sector is feeling. With rising rents, utilities and wage bills meaning every pound raised has to stretch further than ever. The increase in employer National Insurance contributions alone is estimated to cost the sector around £1.4 billion a year.
At the same time, the donor base is shrinking. The CAF UK Giving Report 2025 found that charities now rely on donations from roughly half the population, down from 58% in 2019. That is the equivalent of around four million fewer donors. Many organisations have also spent down the cash buffers that once cushioned a quiet month. Research cited by NCVO suggests one in four charities were forced to draw on reserves during the pandemic, and many have not rebuilt them.
Against that backdrop, a predictable seasonal shortfall is no longer a minor inconvenience. For a charity running close to break-even, the summer gap can be the difference between comfort and crisis. The good news is that predictable problems are solvable problems.
Why the summer gap happens
The dip is rarely caused by any single factor. Instead, several income streams soften at once, while your core costs such as salaries, rent and service delivery carry on regardless.
The usual culprits include:
• Regular givers on holiday. Direct debits mostly continue, but one-off and digital donations fall away as supporters switch off and head abroad.
• Quieter corporate partners. Company decision-makers are out of office, sign-off slows, and payroll-giving or sponsorship conversations stall until September.
• Paused grant cycles. Many trusts and foundations do not meet over summer, so applications sit unassessed and awards land later than you might like.
• Thinner events calendars. Fundraising events cluster in spring and autumn. The summer lull means fewer ticket sales and less event-driven income.
None of these is a crisis on its own. Together, arriving in the same eight to ten week window, they can pull a charity’s cash position lower than its leaders expected, especially if no one mapped it out in advance.
Warning signs your charity is not prepared
How worried should you be? These are the red flags we see most often when a charity is heading into summer without a safety net:
• There is no cash-flow forecast, or the only one that exists is last year’s, untouched.
• Unrestricted reserves are spread thin and no one can say with confidence how many months of running costs they would actually cover.
• Nobody has a clear, current picture of which funds are restricted and which are free to spend.
• Bookkeeping has fallen behind, bank reconciliations do not quite balance and the management accounts are weeks or months out of date.
• Decisions about spending are being made on gut feel rather than numbers.
If three or more of these sound familiar, summer is the moment your financial blind spots become visible, usually at the worst possible time.
A familiar story
Consider a small charity supporting isolated older people across a single county. This is a composite example based on organisations we have worked with and all identifying details have been removed. The staff were passionate, the volunteers were remarkable and yet behind the scenes the charity’s finances had become increasingly difficult to manage.
The volunteer treasurer kept the books across several spreadsheets that never quite reconciled with the bank. Restricted grant funding for a befriending project sat in the same account as unrestricted donations, with no clear line between them. For most of the year this muddle went unnoticed. Then came August.
That summer a major grant instalment was delayed, two events were rained off and online donations dried up as supporters went on holiday. The charity suddenly found itself unable to say whether it could meet payroll, and unsure whether the cash it did hold was even free to use. Trustees spent an anxious bank-holiday weekend trying to reconstruct the numbers by hand.
Our first job was simply to bring order to the chaos: reconcile the accounts, separate restricted from unrestricted funds, and build a rolling twelve-month cash-flow forecast that made the summer dip visible months ahead. The following year looked very different. The trustees could see the gap coming in spring, set aside a modest buffer, timed a small spring appeal to bridge it, and entered the holiday months calm and in control. No bank-holiday panic. Just a clear plan.
Practical steps to build resilience
You do not need a finance department to weather the summer gap. You need a handful of good habits, applied consistently.
1. Build a rolling 12-month cash-flow forecast
A cash-flow forecast is the single most valuable tool for navigating seasonal dips. By projecting expected income and outgoings month by month, you can see exactly when money will be tight and act early. NCVO’s guidance for trustees is clear that strong cash-flow oversight is core to avoiding insolvency. A forecast turns a nasty surprise into a managed event.
2. Understand your reserves policy
Reserves exist precisely for moments like this. Yet many trustees are not sure how much they hold in free reserves or how long it would last. The Charity Commission’s CC19: Charity Reserves – Building Resilience is clear that there is no single “right” level. Trustees must set, review and explain a figure that fits their own circumstances.
This matters more than ever under the new Charities SORP 2026, which now sets out an explicit definition of reserves: the part of a charity’s unrestricted funds that is freely available to spend on its charitable purposes. Every charity, whatever its size, must now state its reserves policy, the amount held and why, or explain its reasons if the trustees have decided that holding reserves is unnecessary. Know your free-reserves figure, confirm it is genuinely unrestricted, and express your runway in months.
4. Manage restricted funds correctly
Restricted funds can only be spent on their designated purpose, no matter how tight things feel. Mixing them up with unrestricted money is not just risky; it can breach charity law. Clear fund accounting means you always know what is genuinely available, so a cash pinch never tempts you into a misstep.
5. Tidy the books before the gap hits
Messy records are hardest to fix under pressure. Getting your bookkeeping reconciled and your management accounts current now, while there is breathing room, means you are reading from a clean, trustworthy set of numbers rather than guessing. (For more on why this matters, see our guide to why good bookkeeping is vital for your organisation).
What SORP 2026 means for your resilience planning
For many charities, summer 2026 arrives just as a major change to charity reporting takes effect. The new Charities SORP 2026 was published in October 2025 and applies to accounting periods beginning on or after 1 January 2026. The first year-ends affected will be 31 December 2026, though charities with shortened accounting periods may feel the change sooner. Getting your finances in order this summer is therefore also a head start on the new rules.
A few of the changes speak directly to financial resilience:
• Three reporting tiers instead of two. Requirements are now set across three tiers based on gross income: Tier 1 for charities up to £500,000, Tier 2 from £500,000 to £15 million, and Tier 3 for those above £15 million. The aim is more proportionate reporting, with clearer, lighter-touch options for smaller charities. These tiers are based on income alone and do not line up with the audit thresholds, so it is worth checking where your charity sits.
• A sharper focus on reserves. As noted above, SORP 2026 defines reserves explicitly and asks every charity to explain its reserves policy and the amount held. The figure in your trustees’ annual report must be consistent with your accounts, and where that link is not obvious you must provide a reconciliation. A tidy, well-understood reserves position is now both a resilience tool and a reporting requirement.
• Plans for the future, for everyone. A summary of the charity’s plans for the future is now expected of charities in every tier, not just the largest. Looking ahead, mapping the year and anticipating pinch points such as the summer gap is becoming part of the reporting baseline.
• New lease accounting. Many leases that used to sit off the balance sheet, such as premises or equipment, will now appear on it as a right-of-use asset and a matching lease liability. This can increase gross assets and affect your free-reserves figure, so it is worth understanding your lease commitments early.
You do not need to master every detail to benefit. The point is that the habits which carry a charity through summer, namely clean books, clear funds and a sensible reserves policy, are the same habits the new SORP rewards. The official guidance is freely available on the Charities SORP microsite if you want to read further.
Why getting organised now changes everything
There is a world of difference between facing the summer gap with a clear forecast and a tidy ledger, and facing it with a shoebox of receipts and a vague sense of unease. The gap itself does not change, but your experience of it transforms entirely. Organised finances turn an annual source of stress into a routine, manageable part of the calendar.
It is also a matter of good governance. Trustees have a legal duty to ensure their charity remains financially sustainable, and SORP-compliant reporting depends on accurate, well-kept records, including a clear statement on reserves in the trustees’ annual report.
With the Charities SORP 2026 now in force and its new reporting tiers in place, well-kept records are more valuable than ever. Order in your finances is not just comforting. It is part of meeting your responsibilities to the people you serve.
