How Long Does a Mortgage Application Take?

Two to six weeks from full application to mortgage offer is typical, and around ten to sixteen weeks from application to holding the keys. Straightforward cases land at the shorter end; anything unusual about your income, the property or the chain pushes it out.

But an average is not much use when you are three weeks in and nobody has called you. What you actually want to know is whether the silence is normal for the stage you are at, and that depends entirely on which stage that is.

Rather than guess from an average, find the stage you are actually at. Each one shows what is happening behind the scenes, how long it usually takes, and — the bit people really want — whether the silence you are experiencing is normal.

An underwriter is checking your income, outgoings and credit file properly this time, and the lender is arranging its valuation of the property.

Normal — don’t worry
  • Being asked for more documents. It usually means the file is being worked on, not that something is wrong
  • Silence for a week or two — most lenders only contact you when they need something
Worth chasing
  • No acknowledgement at all after five working days. Chase your broker or the lender directly
What actually speeds it up
  • Answer document requests the same day. This is the single biggest thing within your control
  • Send exactly what is asked for — a partial statement or a screenshot restarts the request

Timings are typical ranges rather than promises — they vary by lender, by how straightforward your circumstances are, and by how long your local authority takes over searches. Validity periods are each lender’s own published terms: Nationwide gives 90 days on a decision in principle and 180 days on an offer with a 45-day extension available, or 270 days for a new build; Halifax quotes 30 to 90 days and up to six months; Barclays six months. Check your own paperwork, since these do change. General information, not mortgage advice.

How Long Does a Mortgage Application Take?

On average, a mortgage application process can take anywhere between 2 to 8 weeks. Factors such as the lender's backlog, borrower's financial complexity, property valuation, and paperwork can influence the approval time. Engaging a mortgage adviser can help expedite the process.

The mortgage application process can be simplified and expedited if you engage the services of a mortgage adviser. An adviser can liaise with the lender, keep track of the application's progress, and promptly handle any additional documentation required.

Their expertise can significantly reduce unnecessary waiting times and help move your mortgage application forward more efficiently.

What Factors Influence the Mortgage Approval Time?

The duration of the mortgage approval process can depend on various factors such as:

The Lender's Backlog

A lender's own queue is often the largest single delay, and none of it is about you. Application volumes spike after a base rate change or ahead of a stamp duty deadline, and an underwriter working through a backlog can add a week or more before your file is opened for the first time.

Brokers track lender service levels for exactly this reason. Where speed matters more than the last 0.1% on the rate, ask which lenders are currently turning cases around fastest.

The Borrower's Financial Complexity

Complex income takes longer because it needs a human underwriter rather than an automated check. Self-employment, several income sources, bonus or commission pay, contract work and earnings in a foreign currency all fall outside a lender's automated scoring.

The evidence differs too. A self-employed applicant is usually asked for two to three years of accounts or SA302s, against three months of payslips for someone employed — and that gap in paperwork is most of the gap in time.

The Property's Value

The lender needs to assess the property's value before approving the mortgage. If the property valuation takes time, this can delay the process.

Inadequate Paperwork

Missing or inconsistent paperwork is the most avoidable delay and the most common. Each time a lender has to come back for another document, the file usually rejoins the queue rather than being picked up where it stopped.

The usual culprits are bank statements that do not cover a full three months, an address that does not match the electoral roll, payslips with a page missing, and a gifted deposit with no donor letter. Assembling all of it before applying saves more time than anything else you can do.

The Timeline of a Mortgage Application

Understanding the mortgage application timeline can give first-time buyers and home movers a clear idea of what lies ahead. So, let's break down the process into six stages.

Stage 1: Mortgage in Principle

The first step towards acquiring a mortgage involves obtaining a mortgage in principle. This pre-approval from your lender outlines the amount they are willing to lend for your property purchase.

This process is quite simple and can be completed within 24 hours, provided you have all the necessary documents ready. Bear in mind that a mortgage in principle isn't a guarantee of a full offer.

What Documents are Needed for a Mortgage in Principle Application?

To apply for a mortgage in principle, lenders typically require:

  • Proof of income (e.g., payslips)
  • Identification documents (e.g., passport, driving licence)
  • Proof of deposit
  • Bank statements

Stage 2: Full Mortgage Application

Once you have a mortgage in principle and have made an offer on a property that has been accepted, you can progress to a full mortgage application. This application usually takes 24 hours to submit, provided you have all the necessary documents ready.

What Information is Needed for a Full Mortgage Application?

During the full mortgage application process, lenders typically require:

  • Details of the property, deposit amount, and information about the seller's estate agent
  • Proof of identity and address
  • Bank statements (typically from the last three months)
  • Proof of income, including payslips (up to six months' worth)

Stage 3: Property Valuation and Survey

When you apply for a mortgage, the lender usually conducts a 'Standard Valuation'. This inspection, carried out by an independent surveyor, assesses the property's condition, identifies any significant issues, and compares the property's value with similar properties in the area.

The valuation survey usually takes 7-14 days to complete.

Stage 4: Full Mortgage Offer

Once the mortgage valuation survey is complete and the lender's underwriter is satisfied with the results, the lender can make a full mortgage offer. This process typically takes an average of 17 days.

To understand the steps that follow, read what happens after a mortgage offer.

Stage 5: Exchanging Contracts

While your mortgage application is being processed, your solicitor will be conducting the necessary conveyancing. This includes applying for local authority searches, which can take about 4 weeks.

Once your solicitor has your mortgage offer and local authority search results, they can arrange for contract exchange, which takes around 8 weeks.

Stage 6: Mortgage Completion

The final stage of the mortgage application process is completion. This is when the solicitor arranges for the lender to release the funds, allowing you to complete the property purchase.

The time between contract exchange and completion can vary, but the average time is 4 weeks.

Why is My Mortgage Application Taking So Long?

Delays in the mortgage application process can be due to various factors, such as a backlog of applications with the lender, complexities in the borrower's financial situation, or incomplete paperwork. If you're concerned about the length of time your application is taking, contact your lender or mortgage broker for an update.

How long are Mortgage applications currently taking?

The standard mortgage timeline currently runs at around 6-8 weeks. It is possible for this to be less, it depends on the complexity of transaction you require.

For example, a remortgage can take as little as 2 weeks, and switching mortgages is often quicker than a purchase because there's no chain.

How will I know if my Mortgage application is approved?

Once your mortgage application is approved, you will receive a formal mortgage offer from your lender. This official document serves as confirmation that your application has been approved.

Typically, the offer is sent to you by mail, but if you're working with a mortgage broker, they may inform you in advance that it's on its way.

How to Speed Up the Mortgage Application Process

The mortgage application process can be expedited by submitting a well-prepared and complete application. An experienced mortgage broker can guide you through this process, ensuring that all required documents are submitted correctly and promptly.



The question of "how long does a mortgage application take" doesn't have a one-size-fits-all answer. Several factors can influence the timeline, including the lender's backlog, the complexity of the borrower's financial situation, and the property's value.

However, by understanding the process and preparing well in advance, you can navigate the mortgage application process more efficiently and confidently. Remember, every step brings you closer to owning your dream home!
