Conveyancing has a special talent: everything feels fine until it suddenly is not - and then everyone is counting days with three different interpretations and a rising heart rate.
Here are the time traps that tend to do the damage.
The traps that derail timelines
Treating "10 working days" as a vibe, not a defined window
Under the Standard Conditions of Sale commonly used in practice, a Notice to Complete typically triggers a ten working day completion window, and the day of notice is excluded. The exact terms depend on the contract conditions used in your transaction.
Practical takeaway: Do not plan from the date you draft the notice; plan from the date it is given (and exclude that day).
Forgetting the jurisdiction is not just academic
A chain with a Scottish property, or anything Northern Irish, can bring extra bank holidays into play. Count the wrong holiday set and you can make a deadline look safe when it is not.
Practical takeaway: Lock the property jurisdiction early and keep it consistent across the chain.
The exchange-to-completion window is short enough to be fragile
People remember the completion date, but forget the path to get there: funds, searches, redemption figures, undertakings, and internal cut-offs.
Practical takeaway: If you are using a working-day window, one bank holiday in the middle can consume the only slack you had.
Assuming the start day always counts the same way
Some timelines treat the service day as day 0; others count from the next working day. That one-day shift is exactly the kind of thing that becomes a Friday panic.
Practical takeaway: Be explicit in file notes: count from [date], excluding [service day].
CHAPS cut-offs turn "completion day" into "completion morning"
Even when everyone agrees on the date, the practical reality is that completions live inside banking cut-offs.
Practical takeaway: If your plan assumes late afternoon completion, it is not really a plan - it is a hope.
Chains magnify small timing errors
A one-day slip on one file becomes a same-day emergency across the chain. That is not drama; it is arithmetic.
Practical takeaway: Treat deadlines as linked milestones, not isolated points.
A calmer way to plan
Plan the transaction like a sequence:
- Finance conditions
- Exchange window
- Completion
- Notice to Complete (if needed)
Each stage should feed the next, with the correct holiday set applied automatically.

Q: What is a Notice to Complete? A: Under the Standard Conditions of Sale commonly used in practice, a Notice to Complete typically gives 10 working days to complete the transaction or risk contract rescission and loss of deposit. Check the conditions used in your contract.
Q: Is Saturday a working day for conveyancing? A: No. Conveyancing working days are Monday to Friday, excluding bank holidays. Completion usually cannot happen on weekends or bank holidays.
Q: How many working days is a Notice to Complete? A: Under the standard conditions commonly used in practice, a Notice to Complete gives 10 working days. The count typically excludes the day the notice is served. Always check the specific conditions used in your contract.
Conclusion
Most conveyancing delays come from small timing assumptions that compound across a chain. Use the correct jurisdiction, count working days precisely, and treat each milestone as part of a linked sequence. The calmer your planning, the calmer the completion day.
