Completion day is the single most stressful 24 hours of moving house. Exchange is done. The money is leaving your account. Three different solicitors, two estate agents, a remover crew, the family dog and (in Cornwall) probably a tractor blocking the lane are all coordinating around one outcome — you, in the new house, by tea time. This is the survival guide: the legal sequence, the CHAPS timings, the 1pm vacate rule, and the Cornish wildcards that quietly add three hours to everyone's day.
What completion day actually is (legally)
Completion is the moment ownership transfers from seller to buyer. Your conveyancer sends completion funds via CHAPS to the seller's conveyancer. When those funds arrive, the seller's conveyancer authorises the estate agent to release keys. You're now the legal owner — but only from that exact moment, not from when you booked the remover three weeks ago.
The whole chain has to complete on the same day. If you're buying from someone who's also buying, their completion funds must move before they can give you keys. A chain of five properties means five sets of CHAPS transfers in a careful sequence. One slow solicitor delays everyone.
The legal sequence, hour by hour
| Time | What's happening | What you should be doing |
|---|---|---|
| Before 9am | Banks open. Conveyancers start sending CHAPS instructions. | Breakfast. Crew arrives. Load starts. |
| 9-11am | CHAPS payments move through the chain. Each takes 2-3 hours to clear. | Stay near your phone. Keep loading. Make tea. |
| 11am-1pm | Funds arrive at top of chain. Keys start releasing downward. | Expect a call from your estate agent or conveyancer. |
| 1pm | Standard vacate deadline. Sellers should be out by now. | Read meters. Lock up. Hand keys back. |
| 1-3pm | Late completions clear. Long chains may run to 3-4pm. | Drive to new property. Try to arrive before crew. |
| 3pm onward | Anything completing after 3pm is touch-and-go. | Have a plan B for overnight storage. |
Why CHAPS takes hours, not seconds
CHAPS (Clearing House Automated Payment System) is the high-value same-day transfer used for property completions. Banks process CHAPS in batches throughout the working day, not in real time. A typical CHAPS payment takes 2-3 hours from instruction to receipt. If your conveyancer instructs at 9am, the seller's conveyancer often won't see funds until 11am or noon. That's normal — not a problem.
What's not normal: a CHAPS payment that hasn't moved by 2pm. By that point your conveyancer should be on the phone to the bank chasing it.
The 1pm vacate rule (and why it exists)
The 1pm vacate deadline isn't statute — it's industry convention. Your sale contract will specify completion "by 1pm" or "by 2pm" on the agreed date. The seller agrees to be out of the property by that time so the buyer has a half-day to load up and move in. In practice:
- If you're the seller and still loading at 1.30pm, the buyer can technically claim breach of contract, but in practice everyone gives a couple of hours' grace.
- If you're the buyer and the seller's still there at 2pm, your remover may charge a waiting fee (£100-£200 per hour for a crew sat in a van).
- If completion runs past 4pm, some sellers won't be able to vacate that day, and the whole chain may have to roll to the next working day. This is rare but it happens.
The Cornish wildcards
The A30 in summer
If your move involves driving down from up-country, the A30 between Bodmin and Penzance can crawl from late July through early September. A 9am London start arrives in Truro at around 3pm in fair traffic, later in summer. If your crew needs to be loaded by 1pm and unloaded the same day at a Cornish destination, an early-morning start is essential.
Single-track lanes and access issues
Cornwall's lanes catch up-country chains out routinely. A 7.5-tonne lorry that can't pass an oncoming tractor adds 30-60 minutes to a journey. If the lane is single-track to a cottage near Tintagel or off the B3266, the crew may need to shuttle with a 3.5-tonner — adding 2-3 hours. Tell your remover at quote stage, not on completion day.
Coastal weather
Storm Eunice in 2022 closed the Tamar bridge. Winter storms close the A30 over Bodmin Moor periodically. If you're completing in January or February and the forecast looks bad, ask your conveyancer to build in a day's slack between exchange and completion so a delayed day doesn't cascade into a missed mortgage offer.
Chain length
Cornwall chains are often long because so many buyers are also sellers (second-home owners disposing, retirees downsizing, holiday-let owners exiting after the FHL abolition). A chain of six is not unusual. Each link adds another CHAPS payment in series. Ask your conveyancer how long the chain is — a six-link chain rarely completes before 2pm.
What goes wrong (and how to mitigate)
1. Funds delayed
A buyer's bank doesn't release funds on time. The chain stalls. Mitigation: confirm with your conveyancer the day before that completion funds are with them and ready to send.
2. A last-minute search query
The local authority search picks up a query the day before completion (e.g. a discrepancy in title plans). The conveyancer flags it; the lender may pause funds release. Mitigation: searches are usually done weeks before exchange — by completion day this is rare. But if your conveyancer mentions a late query, take it seriously.
3. A chain link drops out
Someone in the chain — usually three properties up — gets cold feet, fails a mortgage offer, or has a family emergency. The chain collapses. Mitigation: stay friendly with your seller and estate agent. Information flows faster on goodwill than on legal channels.
4. Removers can't unload
You complete late. The crew is at the new property. It's 5pm. They've already done a 9-hour day. Mitigation: pre-agree a holding fee structure (£100-£200/hour) and an overnight storage option (£150-£400) with the remover before completion day. Our timing guide covers the realistic hour-by-hour pattern.
5. The new property's not vacant
The seller's removers are still loading at 2pm. You have nowhere to put your stuff. Mitigation: keep a friendly relationship with the seller. Their delay isn't your fault but you'll need to be patient — most conveyancers don't escalate this on day one.
Day-before checklist
- Confirm with conveyancer that completion funds are ready
- Confirm crew arrival time with remover
- Save your conveyancer's direct mobile number
- Charge phones and a power bank
- Put first-night box in the car (kettle, mugs, chargers, prescription meds, snacks, loo roll, bedding for one bed)
- Photograph every room of the old property in good light
- Read meter locations (you'll need to take readings on the day)
- Pack a clean change of clothes for that evening — the box marked "PYJAMAS" goes in your car, not the van
- Buy snacks and drinks for the crew. A morale tea round at 10am pays for itself in finished-the-room speed
What to do if completion's delayed past 3pm
- Call your conveyancer. Ask exactly where the chain has stalled. They should know.
- Talk to your remover. Discuss overnight storage — most Cornwall removers can keep your stuff on the van or in a warehouse for £150-£400.
- Check if your seller can let you in late. Some sellers will hand keys at 6pm if it saves an overnight delay; others can't because they've gone onward.
- Book accommodation. Cornwall Airbnb and Premier Inn capacity exists year-round outside school holidays. A delayed completion to the next working day means one night in a hotel for the family.
- Don't panic. Same-day completions are the most common failure mode in conveyancing, and the entire industry has workarounds for it.
Settling in: the first 24 hours
- Make up one bed. Per adult, per child. Sleep is the only priority.
- Plug in the fridge. Leave upright 4 hours before plugging in if it's been on its side.
- Find the stop tap, fuse box and boiler. Photograph their locations.
- Take meter readings. Photograph all of them on the first evening, even if you already did it earlier.
- Order a takeaway. Cooking on completion night is overambitious. Many Cornwall villages have a single pub or a Chinese — ask your new neighbours.
- Don't unpack 70 boxes tonight. Find pyjamas, find toothbrushes, sleep.
Cornish chains: why they're slow
Cornwall conveyancing has a few quirks that lengthen typical chains:
- High second-home stock. A buyer purchasing a second home now pays the 100% Cornwall Council premium from April 2025, so some buyers are exiting at offer stage.
- Solicitor backlog. Cornwall conveyancers are stretched. Some firms in Truro and Falmouth have 8-12 week waiting lists for new instructions.
- Mortgages and FHL abolition. Owners exiting holiday-let portfolios post-April 2025 add unusual transactions to the market — capital allowances claims, CGT computations, the lot. See our companion piece on selling up after FHL abolition.
- Listed building quirks. Granite cottages with Grade II listings often have title query histories that drag.
The conveyancer relationship
You'll deal with one person at the conveyancing firm. They handle hundreds of transactions a year — yours is not their priority. To get good service:
- Email them, don't call (they bill phone time more than email time)
- Send all documents in one batch, not drip-fed
- Respond same-day to anything they ask for
- On completion day, you can call. They expect chase calls.
If your conveyancer is unresponsive in the week before completion, escalate to the firm partner — don't wait until completion day to discover they're on holiday.
Stamp duty: a 2026 note
From 1 April 2025, the SDLT 0% threshold dropped from £250,000 to £125,000. A £400,000 home-mover purchase that would have cost £7,500 in SDLT before April 2025 now costs £10,000. Your conveyancer files the SDLT return and pays the tax within 14 days of completion. Our 2026 mortgage and SDLT guide walks through the new rates.
The bottom line
Completion day is choreographed chaos, not random chaos. The legal sequence — exchange, CHAPS transfer, keys released, vacate, occupy — is predictable. What's unpredictable is human behaviour at each link. Stay near your phone, keep tea coming, photograph everything, and have an overnight plan B.
