‘Completion’ explained in under 7 seconds

Completion is when a property transaction is legally finalised and the new owners get the keys. It takes place on a date specified at exchange of contracts.

What is completion?

What happens on completion?

What is the significance of completion?

Completion signifies that ownership of and responsibility for the property has transferred from the seller to the buyer.

Agreeing your completion date

Given that the transaction is not legally binding until exchange has taken place, there is generally anything from two to four weeks between exchange and completion, to allow all parties to make moving arrangements.

The more parties in the chain, the more time it is likely to take to find a completion date that suits everyone, so be prepared to compromise and accept you might not be able to agree on your first choice.

Because most people have a full-time job, completions tend to take place on a Friday to give everyone the weekend to get the initial moving in and unpacking done, without having to take more than an afternoon or a day off work.

As such, it’s often the busiest day for removals companies, so once you have an idea of when you’re likely to complete, it’s a good idea to make a tentative booking.

Most removals companies will be happy to ‘pencil in’ a date, although they are unlikely to guarantee it until you pay the deposit.

Can you avoid Friday?

If you are able to agree to complete on a day other than Friday, the transaction is likely to complete earlier in the day, because mortgage companies and solicitors aren’t as busy, and you may be able to get a better price for your removals, so it’s worth making enquiries early on.

In addition, moving on another day allows for:

The buyer's deposit on exchange explained

The deposit that the buyer is required to pay on exchange is different to the ‘deposit’ required by a mortgage lender.

For the purposes of the legal agreement, the deposit on exchange varies from 5-10% or more of the purchase price, which must be lodged with the buyer’s conveyancer as cleared funds, i.e. via bank transfer, a cashier’s cheque or money order, or a cheque that has been cleared by the bank.

As a buyer, if you can ensure your funds are sent over to your solicitor or conveyancer several days in advance of the proposed exchange date, it should help move things along smoothly.

Deposits in a chain

If there is a chain, it is usual that a seller may be using the funds they receive from their buyer to pay for some, if not all of their onward purchase.

As such, the deposit lodged by the buyer at the bottom of the chain may be taken into account and passed up the chain.

For example, if the person at the bottom of the chain (Buyer A) is buying for £150,000 and their seller (Buyer B) is buying for £250,000, the £15,000 deposit lodged by Buyer A can be put towards Buyer B’s deposit, so they will only need to lodge £10,000 with their conveyancer, rather than the full £25,000.

If Buyer C is downsizing and only buying at £200,000, they won’t need to lodge any deposit, as it is covered by the funds already in the chain.

Peace of mind for sellers

As a seller, the buyer’s deposit funds give you peace of mind that they fully intend to proceed to completion and, if they don’t, you will be entitled to keep the full deposit as compensation.

You cannot, however, access the deposit funds until the transaction has completed.

The only exception would be if you required the deposit to be paid to an onward purchase of a new build, where the developer requires the deposit, in which case, the funds would be paid to them and guaranteed by a New Build Guarantee Scheme (such as NHBC).

Can you do building work between exchange & completion?

Yes you can, via a side legal agreement called a ‘key undertaking’.

It’s most commonly used when a property is currently vacant and requires refurbishment or modernisation, in order that the buyers are able to get it up to a standard where they can move in on completion.

The other instance where a key undertaking is employed is if the buyer’s mortgage lender has placed retention on the mortgage funds (i.e. is holding an amount back) until certain remedial works are carried out on the property, and the seller is not willing or able to carry them out themselves.

In this case, granting the buyer access to undertake the required works may be the only way for the sale to proceed.

If the seller agrees to allow access (which they may not) the key undertaking document will need to detail the exact nature of the works you intend to carry out and what will happen if you don’t complete the purchase for any reason.

Key undertakings also often stipulate that the buyer is responsible for the utilities and Council Tax from the date of exchange.

Can I exchange and complete on the same day?

Pros & cons of attended exchange of contracts

An attended exchange of contracts is where the buyer and seller meet in person, together with their legal representatives, to come to an agreement on the terms of the sale/purchase and push through exchange as soon as possible, ideally on the same day.

It tends to mainly be developers and property traders that look to carry out the transaction in this way.

Why do it?

It’s used when one or both parties want to push through the transaction as quickly as possible.

The buyer may want to own and start developing what they see as an excellent acquisition before anyone else gets hold of it, or the seller might have a pressing need to release their equity as soon as possible.

When to consider it

When a property is highly desirable and of great interest to a number of parties, if a buyer is able to push through a quick purchase in this way, that may give them an advantage and allow them to secure the property.

From a seller’s perspective, a quick sale will allow them to access capital that they may have an immediate need for – either to complete another purchase or to satisfy some other financial commitment.

It is typically only possible to reach exchange in this way if you’re a cash buyer, as most mortgage lenders will require more time to have searches, a mortgage valuation and possibly a home buyer’s survey carried out and paid for by the buyer, not to mention the time they take to prepare and issue a mortgage offer.

How it’s done

Pros & cons

The main thing to be aware of is that all the risk is placed on the buyer, so it is not for someone who’s inexperienced.

Generally, it is only well-capitalised, professional property investors who attempt attended exchanges.

Pros

Cons

Can you pull out after contracts exchange?

The first thing to say is that either party pulling out after exchange is extremely rare.

At the point of exchange, both the buyer and seller are contractually committed to completing, so pulling out is a breach of contract and attracts financial penalties.

Advice for buyers

Advice for sellers

How to speed up exchange & completion

The key to moving the transaction along as quickly as possible is for all parties to respond to requests for information or action right away.

If buyers or sellers are unclear about the process or slow to respond, or solicitors and conveyancers don’t process things as quickly as they could, transactions can drag on for really no good reason.

There should be good communication between the buyer, their legal representative and their mortgage broker; similarly, the seller should be in touch with their conveyancer and estate agent to make sure things are moving along and there are no problems.

The estate agent should be in touch with all parties, checking in to progress the sale on a regular basis.

It also helps if you can agree an exchange and completion date to aim for right from the start, to give everyone a timescale to work towards.

This can help to uncover issues such as holidays which can delay progress.

Tips for buyers

Tips for sellers

What should the estate agent being doing during all this?

A good ‘no sale, no fee’ estate agent – one who’s experienced, knowledgeable and proactive – can really help achieve a smooth sale and purchase and it’s in their own interest, as they don’t get paid unless the transaction completes!

Buyers: What needs to happen before I can exchange?

Getting ready to exchange contracts is a matter of getting the right legal and financial documentation signed and funds being in the right hands.

As a buyer, you must make sure:

Your conveyancer must:

Sellers: What needs to happen before I can exchange?

As the onus is more on the buyer than the seller in the transaction, there is not as much for you to do.

As a seller you must:

How do solicitors & licensed conveyancers exchange contracts?

In the past, solicitors would meet up in person to physically exchange contracts, however, these days it is done over the telephone.

They verbally confirm and agree the terms of the contract, the completion date and that they hold the required documentation and funds.

Once each solicitor in the chain has, in turn, agreed all this with the corresponding buyer’s/seller’s solicitor, contracts are said to have been exchanged.

What is the process?

  1. On the day of exchange, the solicitor or conveyancer at the bottom of the chain has to contact the next one up and confirm to them that they’re in receipt of a signed contract of sale and deposit funds and also confirm the terms of the sale and completion date.
  2. They will give the next legal representative up the chain a ‘release’ time to come back to them to confirm the exchange, for example this may be 4pm or 5pm that same day.
  3. The next solicitor or conveyancer has to contact their client’s seller’s legal company in the same way, until the solicitor at the top of the chain has been reached.
  4. The exchange then needs to be confirmed back ‘down’ the chain, to reach the first legal company within the release timeframe. If that doesn’t happen, the exchange process will have to be re-started the next day.

How long does it take to exchange contracts on the day?

Why might exchange not happen on the day it’s supposed to?

Often this is down to a conveyancer being unavailable to take or make the required phone calls, either because they’re out of the office or in a meeting.

Regardless of the reason, it does suggest the solicitor or client may not be acting in the best interest of their client and it’s very frustrating for all parties.

Other reasons maybe required paperwork which was promised and not received, such as offers from lenders or it could be deposits being promised but not being transferred by buyers in time.

Other key reasons include buyers and/or sellers going on holiday or being away with work and not leaving the appropriate instructions with their legal company.

Bear in mind that most legal companies work on cases which they have to complete legally that week first, then, if time, look at property transactions which are expected to exchange and then progress other cases.

As a result they may intend to exchange on a certain date but when they look at the file, perhaps on the one day or morning they have spare, they realise they are missing key information required.

This is particularly the case if they are not a proactive legal company or overload the legal department with too many cases.

Make sure you pick a conveyancing firm that is proactive, has the most up to date technology and is keen to achieve exchange and completion dates you set rather than ones that suit them.

What happens between exchange and completion?

Once exchange has taken place and all parties are legally obliged to complete, everyone can make their arrangements for the agreed completion day.

How long between exchange and completion?

The length of time between exchange and completion is whatever all the parties involved agree to, but it’s usually one or two weeks.

That gives everyone time to organise themselves for completion:

What happens on completion day?

What can cause delays on completion day?

The main cause of delay is usually the transfer of monies. If a mortgage is involved, the funds have to be sent by the lender to the buyer’s solicitor or conveyancer, who must then pass them straight on to the seller’s legal company.

Provided the lender makes the transfer first thing in the morning and the buyer’s solicitor or conveyancer attends to the onward transfer right away, completion can usually take place by 12 noon.

However, if the seller’s legal representative has not received the funds by 3pm, completion may not happen until the following day – although this is very rare.

The other thing that can hamper the process is if a party in the chain has miscalculated the monies required to complete, which includes stamp duty and any agents’ fees plus VAT.

Last-minute transfers can mean the transaction doesn’t complete until later in the day.

From a logistical perspective, people not starting the removals process in good time can cause delays.

Sometimes the transaction has completed but a buyer is unable to move into their new home because the seller has not yet vacated it.

In this case, if costs are incurred, such as additional removals charges or there is the need for overnight accommodation, the seller can be pursued for costs.

These are good reasons why it is worth aiming for completion earlier in the week so there is still time to complete prior to the weekend, rather than relying on everything going well on a Friday.

What happens if completion doesn’t take place?

If either party fails to complete on the contractually agreed date, they are in breach of contract and there are penalties.

How can I make completion day less stressful?

The key to your completion day running smoothly is effective planning.

Understanding the buyer’s completion statement

The buyer will get a completion statement from their solicitor on exchange, detailing exactly what monies have been paid, are due to be paid and what is required to complete. It includes:

(A) The total amount you will pay the seller on completion

(B) Fees, taxes and charges

(C) Monies already paid/received by the legal company

Before completion can take place you have to pay the balance to your conveyancer -> (A + B) – C = Balance Payable

Common questions

What is the difference between exchange of contracts and completion?

Exchange of contracts is the point at which the buyer pays a deposit and the sale/purchase contract becomes legally binding.

Completion is when the balance of the payment for the property is passed over to the seller’s solicitor and ownership transfers to the buyer.

What is the date of completion?

The date of completion is one that is agreed by both parties prior to exchange, commonly one or two weeks later. It is the date on which full payment is made to the seller, ownership transfers to the buyer and moving day takes place.

How much time is REALLY needed between exchange and completion?

Legally, exchange and completion can take place on the same day.

However, if a mortgage is required for the purchase, the lender might require five working days between the two and it is much less stressful for all parties if there is a period of time after the transaction becomes legally binding, to give everyone time to make moving arrangements.

If you are trading down, think about how long it will take you to downsize your contents.

It may take weeks or even months, so if you need more time between exchange and completion, do make sure you secure this early on in the process.

What does completion mean when you are buying a house?

When you’re buying a house, completion means you have paid the seller (commonly with a combination of your own money and mortgage funds from a lender) and ownership of the property has passed to you.

It is the day you can move in.

What does it mean when you exchange contracts on a house?

Exchanging contracts is the point at which the buyer and seller are both legally bound to complete the transaction.

The buyer lodges a deposit with their solicitor and if either party pulls out of the agreement, which is very rare, there are financial penalties.

Can you exchange contracts without a completion date?

No, both parties must agree a date, which is inserted into the contract before exchange can take place.
