How Long Does a Mortgage Take? From Application to Offer to Completion

A mortgage application typically takes two to four weeks to reach a formal offer once it is submitted, and the whole purchase usually runs eight to sixteen weeks from an accepted offer to completion, depending on the chain and the conveyancing. This guide sets out what happens at each stage, how long each one normally takes, how long a mortgage offer lasts once it arrives, and where the weeks are most often lost. Mortgage One is a whole of market mortgage adviser managing purchase and remortgage applications through to offer and completion for borrowers across the UK.

How long does it take to get a mortgage from start to finish?

Getting a mortgage takes around three to six months from the first affordability check to picking up the keys. The agreement in principle takes minutes, the full application two to four weeks to reach an offer, and conveyancing typically twelve to sixteen weeks from an accepted offer to completion, with the mortgage running in parallel to the legal work.

The stages run in a fixed order. An agreement in principle comes first, then an accepted offer on a property, then the full application to the lender, the valuation, underwriting and the formal mortgage offer. The solicitor’s searches, enquiries and contract work run alongside the application and usually finish after it, which is why the mortgage offer is rarely the thing holding up exchange. HSBC’s own timeline guide puts the whole process at an average of about six months from starting to search to completion, and around twelve weeks between offer and completion.

Where the six months goes is mostly the property side: finding the home, agreeing the price and waiting for the chain. The mortgage itself occupies a smaller slice, and a borrower who has the mortgage in principle and the documents ready before offering shortens it further. Remortgages and product transfers, which have no chain, run to a different clock covered at the end of this page.

How long does a mortgage application take to reach an offer?

A mortgage application takes two to four weeks from submission to formal offer, the range MoneyHelper quotes, and HSBC puts its own cases at up to a couple of weeks. A physical valuation is usually booked within 48 hours and reported within five working days, and the offer follows the underwriter’s final check about a week later.

The application week by week looks like this. Days one to three: the application is keyed, documents are uploaded and the lender runs a hard credit search. Days three to ten: the valuation is instructed and carried out, either as an automated desktop valuation that returns almost immediately or a physical inspection that NatWest says usually takes place within 48 hours and is reported within five business days. Days ten to twenty: underwriting, where the lender checks payslips against bank statements, confirms the deposit source and raises any queries. The offer follows once the underwriter is satisfied and the valuation supports the loan.

That is how long mortgage approval takes on a clean case, and how long it takes to get a mortgage offer stretches beyond four weeks only when something stalls at underwriting. The mortgage application guide sets out the eight steps and the documents each one needs, and the mortgage approval guide explains what the underwriter is checking so the queries can be answered before they are asked.

Does applying through a broker change how long it takes?

The lender’s processing time is the same whichever route the application arrives by, so applying through a broker does not make the underwriter faster. What a broker changes is how often the case goes back for missing documents, the main cause of applications running past four weeks, and the choice of lender, since service levels vary widely.

No lender publishes a figure showing broker cases completing faster, and the honest answer is that a clean direct application and a clean broker application take about the same time. The difference is in the proportion of cases that are clean. A broker packages the income evidence in the form the lender’s underwriters expect, flags a gifted deposit or a large unexplained credit before the underwriter finds it, and picks a lender whose current turnaround suits the deadline rather than one whose service queue has grown. Lenders’ service levels move week to week, and that information sits with the intermediary desks rather than on the public site.

The other time saving is avoiding a decline. A declined application costs the weeks already spent plus a hard search on the credit file, and the declined applications guide explains why reapplying immediately with a second lender often repeats the problem. Placing the case with the right lender first time is where a broker’s knowledge of criteria buys the most time.

How long does a mortgage offer last and can it be extended?

A mortgage offer typically lasts six months. HSBC issues offers valid for 180 days, Nationwide for six months plus a 15-day grace period, and Santander for six months from issue, while Barclays runs its six months from the application date rather than the offer date. Extensions are available on request, at the lender’s discretion, and can be short.

Extension policy is where lenders differ most. Nationwide allows a 45-day extension that includes its grace period, Barclays allows only two weeks on a standard purchase but six months on a new build, and Skipton adds three months on new builds only. MoneyHelper notes that extensions, where granted, run from one to six months and that a lender is not obliged to grant one, so an offer that is about to expire on a delayed purchase can mean a fresh application at whatever rates are then available. The lender may also ask the solicitor for an updated certificate of title before extending.

New build purchases carry the longest validity because completion can sit months beyond exchange. Santander extended its standard new build offer validity to nine months, and Skipton issues nine months on new build against six on other purchases. The new build mortgages guide explains why the build contract’s long-stop date has to be set against the offer expiry before the application goes in.

What slows a mortgage application down and how to avoid it

The most common delays are missing or inconsistent documents, a deposit that cannot be traced through bank statements, new credit taken during the application, a valuation that comes back below the purchase price, and slow local authority searches, which can take more than 25 working days in some areas. Leasehold flats add lease enquiries and management pack delays on top.

Document problems are the ones the borrower controls. Payslips that do not reconcile to the salary credits on the bank statements, an employment gap with no explanation, a large credit into the deposit account with no paper trail, or a car finance agreement taken out between the agreement in principle and the application each generate an underwriter query, and each query adds days. Supplying three months of statements for every account, including the one holding the deposit, at the point of application removes most of them.

A down-valuation is the delay that changes the loan. If the lender’s valuer reports a lower figure than the agreed price, the loan-to-value rises, the product may no longer be available at that band, and the borrower either finds more deposit, renegotiates the price or accepts a higher rate. Any of those reopens the application. Whether to commission a fuller survey alongside the lender’s valuation is covered in our guide on whether you need a survey, because a condition report that arrives before exchange is worth more than one that arrives after it.

From offer to exchange and completion: the conveyancing weeks

Conveyancing typically takes twelve to sixteen weeks from an accepted offer to completion, and exchange to completion averages about one week, although the two can happen on the same day. The mortgage offer is usually in place well before exchange, so the solicitor’s searches, enquiries and the chain set the pace from this point.

HomeOwners Alliance breaks the period into roughly two weeks of pre-contract work, around four weeks while the mortgage is arranged, two to ten weeks on draft contracts and enquiries, then about a week from exchange to completion. The searches are the wild card: local authority searches vary by council and can exceed 25 working days, which is why a solicitor who orders them on day one rather than after the mortgage offer saves the most time.

The chain is the other variable. A first-time buyer with no property to sell buying from a vendor with no onward purchase can complete inside eight weeks. A three-link chain moves at the speed of its slowest solicitor and its least organised buyer. The first-time buyer mortgage guide covers the documents and the deposit evidence that keep the shortest chains short.

How long does a remortgage or product transfer take?

A remortgage to a new lender takes around four to twelve weeks from application to completion, and HomeOwners Alliance advises allowing up to three months. A product transfer with your existing lender completes in around a week, because there is no valuation, no conveyancing and usually no fresh affordability assessment on a like-for-like balance.

The remortgage has no chain, which removes the biggest source of delay on a purchase, but it keeps the legal work, because a new lender’s charge has to be registered against the property. Free legal packages included with many remortgage products are convenient but can be slower than a conveyancer you appoint, and where the current deal ends soon that difference matters. Because a new lender’s offer lasts around six months, the remortgage can be started up to six months before the current deal ends and dated to complete on the day it expires.

The product transfer is the fast route for anyone who has left it late or is already on the standard variable rate, since most lenders can apply the new rate from the next payment date. The remortgage advice guide sets the two routes against each other on total cost rather than speed alone, and the product transfer guide explains when the switch window opens with each lender.

FAQs

1. How long does it usually take for a mortgage to be accepted?

Two to four weeks from submitting the full application to receiving the formal offer is typical. The valuation is booked within a couple of days and reported within about five working days, and underwriting fills the rest. Cases with complex income, a large gifted deposit or a down-valuation take longer.

2. Can I get a mortgage in two weeks?

Sometimes. HSBC puts its own application-to-offer time at up to a couple of weeks, and a clean case with an automated valuation, complete documents and no underwriter queries can reach offer inside ten working days. Completion still depends on the solicitor and the chain, so two weeks to offer does not mean two weeks to keys.

3. How do I know if my mortgage application is approved?

The lender issues a formal mortgage offer document to you and to your solicitor. Until that document arrives, an agreement in principle and a completed valuation are stages, not approval. The offer states the loan, the rate, the conditions and the expiry date.

4. What can fail a mortgage application?

Income that verifies lower than declared, undisclosed credit commitments, bank statement conduct such as returned payments or gambling, a deposit that cannot be evidenced, a property that fails the lender’s criteria or valuation, and a change in circumstances between the agreement in principle and the application.

5. Does a mortgage offer mean it is accepted?

Yes. A formal mortgage offer is the lender’s binding commitment to lend on the stated terms, subject to the conditions in the offer and to nothing material changing before completion. It is the point at which the solicitor can proceed to exchange.

6. Can anything go wrong after a mortgage offer?

Yes. The offer can expire before completion on a delayed purchase, the lender can withdraw it if your circumstances change or the property does, and a new credit search before completion can pick up new borrowing. Keeping finances unchanged between offer and completion avoids most of these.

7. Can you extend a mortgage offer?

Usually, on request and at the lender’s discretion. Nationwide allows 45 days, Barclays two weeks on a standard purchase and six months on a new build, and some lenders re-issue rather than extend, which may mean a fresh credit check. Ask several weeks before expiry rather than days.
