Renewal Season: The Q4 Contracts You Should Be Looking At Now

September is when businesses come back to their desks and start thinking about the final quarter. Budgets, headcount, plans for the new year.

It is also, for a large number of UK businesses, the last month in which they can do anything about their January renewals.

That is not a coincidence of timing. It is arithmetic, and it catches out organisations every year.

Why so many contracts renew in the same fortnight

Look across a typical SME's supplier agreements and the end dates cluster in a small number of places: 31 December, 31 March, and the anniversary of whenever the business started buying seriously.

There are structural reasons for this. Many businesses align supplier contracts to their financial year. Suppliers themselves push for calendar-year terms because it simplifies their own reporting. Software vendors often default to a 1 January start when a purchase is made in the autumn budget round. And once one contract is on a calendar year, it becomes easier to align the others.

The result is a concentration of renewal dates around the turn of the year — and a corresponding concentration of notice deadlines about ninety days earlier.

Which is now.

The arithmetic nobody does in September

Take a contract expiring 31 December with a 90-day notice period. The last day to serve valid notice is 2 October.

A contract expiring 1 January with the same notice period: the deadline is 3 October.

If the notice period is 120 days, both deadlines have already passed.

And if the contract requires notice to be served by post to a registered office — which, as covered in the piece on evergreen agreements, is more common than people expect — you need to allow days for delivery on top.

So the practical position in early September is this: for anything renewing at the turn of the year, you have roughly three to four weeks of genuine decision-making time left. Not three months. Weeks.

What "decision-making time" actually means

Serving notice is a two-minute administrative act. Deciding whether to serve it is not.

If you intend to leave a supplier, you need an alternative. Finding one means scoping the requirement, approaching two or three candidates, comparing proposals properly rather than on headline price, and satisfying yourself that migration is feasible. That is rarely less than a month, even for a straightforward service.

If you intend to stay but want better terms, you need the notice deadline as leverage. A renegotiation conducted three months before the deadline is a negotiation. One conducted three days before is a request for a favour. As the interview on how supplier sales teams operate put it: knowing when to buy is useful, but knowing when you are legally free to leave is essential.

Either way, the work happens now, not in December.

What to do this week

This is a two-hour exercise, and it is worth doing properly.

1. List every contract expiring between 1 December and 31 March. Not just the big ones. Include software subscriptions, connectivity, insurance, facilities, waste, maintenance and any professional retainers.

2. For each, find the notice period and count backwards. Write the resulting date down. That date, not the expiry date, is the one that governs your options.

3. Sort by that date and identify anything already past. For those, your realistic options are to accept the renewal and diarise properly for next year, or to check whether the contract allows termination during the renewal term. Some do, with a shorter notice period.

4. For anything with a deadline in the next six weeks, make a decision now. Stay, leave, or renegotiate. "We'll look at it in November" is a decision to renew, whether or not anyone intends it as one.

5. Check how notice must be served. Written notice to a registered office, marked for a named role, is common. An email to your account manager frequently does not satisfy the clause, and a supplier disputing invalid notice can cost you a full further term.

The three questions worth asking about each one

Is this still the right service? Businesses change faster than their contracts. Scope agreed two years ago may no longer match how you operate.

Is the price still competitive? Especially where an indexation clause has been quietly applying every year. A rate that was market-rate in 2024 has compounded twice since.

What would leaving actually cost? Not just the price difference — the transition itself. If the switching cost exceeds the saving, staying is the right answer, and it is better to know that deliberately than by default.

Next year's version of this problem

The reason this happens every autumn is that the notice deadline exists only in the contract. It is not a date anyone receives a reminder about, and it is not the date written in the renewal column of most spreadsheets.

The fix is not complicated. When a contract is signed, record two dates rather than one: the expiry date, and the expiry date minus the notice period minus however long you would realistically need to find an alternative. That second date is the one that should appear in a calendar.

For a contract with a 90-day notice period where switching would take a month, that means a reminder five months before expiry. It feels excessive when you write it down. It feels entirely reasonable in the week you need it.

Timemy calculates notice deadlines from your contract terms and alerts before they pass, rather than on the expiry date itself. See how contract reminders work.

---

The short version: if you have contracts renewing on 1 January and a 90-day notice period, your deadline is the first week of October. Spend two hours this week listing every contract expiring between December and March, calculate the notice deadline for each, and make an actual decision on anything falling due in the next six weeks. Deferring the decision is the same as renewing.
