The Deadline Dictionary: Translating ‘Close of Play’ Into an Actual Time

It is Sunday evening. On Friday at 4:58pm you sent the final draft because the client asked for it ‘by close of play’. At 9:12am on Monday they reply: ‘Sorry, I meant before I left on Friday.’ You have spent the weekend half-watching your inbox. Nothing is wrong, exactly. But something has gone wrong.

UK client deadlines are full of soft edges. ‘Close of play’, ‘first thing’, ‘end of week’, ‘by lunchtime’ — they sound friendly, and they usually are. They are also a small administrative trap. In 2026, with hybrid teams, async tools and clients in three different postcodes, the phrase ‘close of play’ is less shared than ever. Your job is not to become a human dictionary for free. Your job is to get a clock time on the thing and get on with the work.

The phrase is not the problem. The missing clock is.

Close of play, COB, EOD, end of week: these are not lies. They are shorthand. In a busy office, shorthand saves time. For a freelancer, shorthand costs time because you are the one who has to guess which hour of the day the client has in mind. Guess early and you look keen but rushed. Guess late and you look unreliable. Guess Friday evening and you have given away your weekend to a deadline that may not have needed you until Monday.

The fix is not to send a terse email asking the client to ‘please specify a precise time’. That reads like a parking ticket. The fix is to offer a specific time, explain why it helps, and let them correct you if needed. More on that below.

The common phrases, translated

Here is a working dictionary. It is not official. It is not legally binding. It is, however, better than nothing.

• Close of play / COB / COP: In London finance and legal offices, this often means 5pm or 5:30pm. In creative agencies it can mean 6pm or later. In a regional SME it usually means 5pm, and on a Friday it can mean 4pm if someone has a train to catch. Treat it as 4pm unless you have a better reason to believe otherwise.
• End of day / EOD: Often 5:30pm, but some clients use it to mean ‘before I go to bed’. Do not assume midnight. Do not assume they will still be at their desk at 5:29pm.
• First thing: Usually before 9am, or before the client’s first meeting. If the work is for a 10am meeting, ask for the meeting time and work backwards. ‘First thing’ is a mood, not a time.
• End of week: Usually Friday at 5pm. Occasionally it means ‘before the weekend starts properly’, which can be Friday lunchtime. Rarely it means Sunday night. If your client works weekends, ask. Do not volunteer your own weekend to find out.
• By lunchtime: Noon or 1pm. In the UK, lunch is a flexible concept. If the client has a 12:30pm handover, lunchtime means 12:30pm. If they are in a meeting all morning, it might mean 2pm. Get the handover time.
• This afternoon: Anywhere from 12:01pm to 5:59pm. If you receive the request at 11:30am, reply with a time. ‘I’ll send by 3pm’ is clearer than a hopeful nod.
• ASAP: Not a deadline. It is a feeling. Treat ‘as soon as possible’ as ‘today if I can, but I will confirm a time so we both know what possible means’.
• Before you finish: Whose finish? Yours or theirs? This phrase is a small act of aggression dressed as politeness. Answer with a time.

London is not the whole country, and the clock is not the culture

There is a lazy assumption that London clients are later and regional clients are earlier. It is sometimes true and sometimes nonsense. A City law firm may close at 5:30pm sharp because the partner wants to catch a train. A Bristol agency may still be firing off edits at 7pm because the creative director is on a roll. A Glasgow client may say ‘end of play’ and mean 4:30pm on a Friday because that is when the office actually empties.

The safer assumption is not about geography. It is about context. Finance, legal and public-sector clients often have a clearer internal cut-off because someone else is waiting for the work. Creative agencies and founder-led businesses often run later and vaguer. A client who works from home might start at 7am and finish at 3pm. A client with a school run might vanish at 3:15pm and reappear at 8pm. None of this is unusual. It just means the phrase ‘end of play’ is doing a lot of heavy lifting.

The cost of guessing

Guessing is expensive in ways that do not show up on an invoice. You block out Friday afternoon. You turn down a walk. You eat lunch at your desk. You send at 5:02pm. The client replies on Monday: ‘No rush, I was off Friday afternoon.’ You have paid for their ambiguity with your own evening.

Or you guess early. You send at 2pm and the client says, ‘I meant before you finish — I won’t look at it until tomorrow.’ Now you have set a precedent that you are always available early. Next time they ask for ‘close of play’, they will expect 2pm. That is how a vague phrase becomes a quiet scope creep.

A simple email template that does not sound pedantic

Use this when a client gives you a fuzzy deadline and you need a real one. Keep it short. Lead with willingness, then ask for a clock time.

Hi [Name],

Thanks — happy to get this over to you. Just so I can plan the week properly, could we put a clock time on ‘close of play’? I’ll work to 4pm on Friday 13 November unless I hear otherwise. If it needs to be with you before a specific meeting or handover, tell me the time and I’ll work backwards.

Best, [Your name]

That email does three useful things. It shows you are organised. It gives the client a specific time to accept or correct. And it creates a written record if ‘close of play’ somehow becomes ‘I thought you knew I meant 2pm’. You are not asking permission to do the work. You are asking for a calendar fact.

If you use a project management tool, put the exact time in the task and send a calendar invite for the delivery slot. A time in an email is good. A time in a calendar is better. A time in a calendar that the client has accepted is very hard to argue with.

When to push back, and how

If the deadline is unrealistic, do not just say yes. Say what you can do and when. ‘I can send the full draft by Monday 9am, or the first three sections by Friday 3pm. Which is more useful?’ That is not difficult. It is professional. It also protects you from a Friday evening scramble that nobody actually needed.

For Friday deadlines, set your own internal cut-off on Thursday afternoon. Send the draft then, and say, ‘Sending this ahead of your end-of-week deadline so you have it before the weekend.’ If the client wanted it earlier, they will tell you. If they did not, you have bought yourself a buffer and a small amount of goodwill.

The two-line rule for your own replies

When a client gives you a vague deadline, reply with an exact date and time in your first two lines. Not in paragraph four. Not in a postscript. Right there, where they will see it. ‘Great — I’ll send this by 3pm on Friday 13 November.’ If they do not correct you, you have a working agreement. If they do correct you, you have saved yourself a wasted afternoon.

Vague deadline phrases are part of UK business dialect. You do not need to stamp them out. You just need to translate them before they translate into your weekend. Keep the tone friendly, keep the clock precise, and keep the Friday evening for yourself.
