Before the Lights Go Out: Rehearsing December Cover in One Afternoon

December is not usually a quiet month in UK advisory firms. Deadlines cluster, clients want matters closed before the year end, and the people who normally make decisions begin to take leave. The risk is rarely that everyone is away at once. It is that nobody has tested, in advance, who will decide what when the usual partner or manager is not available.

A short rehearsal can reduce that risk without turning into a policy project. The aim is to run a single afternoon stress test against live work, then leave behind four practical outputs: a one-page cover memo, an authority schedule staff can actually apply, one route for urgent matters, and a short client communication that sounds controlled rather than apologetic.

Start with live work, not a blank template

Choose two or three client matters that are likely to require attention between mid-December 2026 and the first week of January. They should include at least one matter with a statutory or contractual deadline and one where the client may simply expect a quick answer.

For each matter, list the tasks due, the decisions likely to arise, and the person who would normally make those decisions. Then ask who will be available. The gap between those two lists is the real cover plan. A generic rota does not show it; a matter-by-matter review does.

This is also the point to distinguish cover from deputy arrangements. Cover is day-to-day continuity: answering queries, keeping files moving and spotting issues. A deputy carries authority to make defined decisions. Confusing the two is how junior staff end up either overstepping or waiting for permission that cannot arrive.

The one-page cover memo

The cover memo should fit on one page and be written for the person holding the file, not for the file itself. It should state the dates of absence, the named cover for each matter, the client contact, any commitments already made, decisions reserved to a partner, and the escalation route.

Keep it concrete. Rather than saying a partner is away, state the dates and the boundaries: for example, that routine correspondence may be issued, that deadline extensions up to a stated period may be agreed, and that any fee variation or regulatory notification must be referred. The memo should also identify what must not happen without approval, such as issuing a formal opinion or committing to a revised scope.

The memo is not a substitute for the engagement letter. It is an internal control that makes the engagement letter workable during a period of leave. Store it with the matter and send it to everyone named in it. A memo that exists only in a partner's out-of-office reply is not a control.

Authority limits staff can apply

Authority limits fail when they are expressed only as grades or job titles. They work when they are tied to actions. A short schedule can cover the common December decisions: routine client correspondence, agreeing a short extension, instructing a third party, varying a fee, making a regulatory filing, and responding to a data incident or complaint.

For each action, set the level at which it can be taken, the person who must be told, and the point at which it must stop and escalate. Routine correspondence may sit with the file handler. A short extension may sit with a manager up to a stated number of working days. Fee variations and regulatory notifications should normally require partner approval. A data incident should follow the firm's existing incident route immediately, not wait for a partner to return.

Include a simple stop rule: if the action is not listed, or the limit is unclear, escalate. That is safer than relying on individual judgement in a sparse office. Staff should also record decisions made under the schedule, so that the returning partner can see what changed and why.

One urgent-matters route

Firms often create three urgent routes by accident: a partner's mobile, a shared inbox and an informal message to a manager. The result is that nobody knows which one is being monitored. December cover should have one published route, with a named backup and a clear triage test.

Urgent matters are not simply matters that feel pressing. Define them: a statutory deadline at risk, a client emergency, a reputational issue, a suspected data breach, a payment that cannot be made, or a regulatory notification. Set a response expectation for that route and keep a short log of what comes in and who handled it.

Partners should resist the habit of checking email quietly while on leave. If they do, the formal route becomes decorative and staff learn to bypass it. A fixed daily handover, even a brief one, is usually more effective than intermittent oversight.

Telling clients without alarming them

Clients do not need a full internal rota. They need to know that nothing will stall. A short note before leave can confirm the dates, name the person covering the matter, give the urgent contact route and state the expected response time for routine queries.

Avoid language that suggests a skeleton service. Phrases such as limited cover or reduced capacity invite concern. A calm statement of arrangements is better: who is covering, how to reach them, and what will happen to any matter that cannot wait. For clients with known December events, a personal note is preferable to a generic circulation.

Update voicemail messages and email auto-replies to match the note. Inconsistency between a reassuring client email and an auto-reply that gives no contact route undermines the exercise.

The afternoon run-through

Set aside two to three hours. Map the live matters first. Draft the cover memo and authority schedule from that map. Then test them with two scenarios: a client asks for a deadline extension, and a third party raises an issue that could affect a filing. Ask the named cover to state what they would do and where they would stop. If the answer requires a call to someone who is unavailable, the plan needs adjusting.

Finish by drafting the client note and checking the urgent route. Record the gaps, assign an owner and set a date for completion. The output should be short enough to use, not comprehensive enough to admire.

By the end of the afternoon, a firm should have a one-page memo per significant matter, a single authority schedule, one urgent route and a client communication ready to send. That is a modest amount of work. It is also the difference between leave that is genuinely covered and leave that merely looks covered on the rota.
