How long does a mortgage application take? UK timeline 2026

How long does a mortgage application take? For most people moving home or buying for the first time in the UK, the application stage, from a full submission to receiving a mortgage offer, takes around 2 to 6 weeks. Add in conveyancing and the wait for a completion date, and the whole journey from first enquiry to getting the keys typically runs to 3 to 6 months.

Every case is different. A straightforward, employed applicant with a clean credit file and no property chain can move through the stages quickly. Someone who's self-employed, has a complex income, or is buying in a long chain should expect longer at almost every stage. The table below shows what happens at each step and roughly how long it takes.

An Agreement in Principle (also called a Decision in Principle or Mortgage in Principle) is a lender's conditional indication of how much they may lend you, based on a credit check and a basic assessment of your income. It is not a guarantee that your full application will be approved, it's an early indicator, useful for making an offer on a property with more confidence.

Soft search vs hard search

Some lenders run a soft credit check for an AIP, which doesn't appear to other lenders and has no impact on your credit score. Others run a hard search, which leaves a visible mark on your credit file. If you're planning to shop around for an AIP with more than one lender, ask which type of check they use, repeated hard searches in a short period can affect how other lenders view your application.

How long is an AIP valid for?

Most Agreements in Principle last 60 to 90 days. If your property search takes longer than expected and your AIP lapses, you'll usually need a new one, which can mean a fresh credit check. If your circumstances or credit file have changed in the meantime, the amount you're offered could change too.

Once your offer on a property has been accepted, your Agreement in Principle turns into a full mortgage application. This is where the lender asks for the documents that back up everything you've told them, and most lenders take 1 to 5 business days to log and review a complete submission.

Submitting a clean, complete set of documents the first time is one of the biggest factors in keeping this stage short. Missing paperwork is one of the most common causes of delay at this point, because the lender simply pauses your case until they receive what they've asked for.

If you're self-employed, lenders typically ask for two to three years of SA302 tax calculations (or tax year overviews) and an accountant's reference, rather than payslips. This usually takes longer to gather, so start early if you know you'll be applying soon.

Underwriting is where a lender's underwriter checks that your application stacks up: your affordability, your credit history, your income stability, and whether the property itself is suitable security for the loan. For a straightforward employed applicant with a clean credit file, this stage usually takes 1 to 2 weeks.

More complex cases take longer. Self-employed applicants, contractors, people with multiple income streams, or anyone with adverse credit in their history should expect underwriting to take 2 to 3 weeks or more, as the underwriter has more to verify.

The most common causes of underwriting hold-ups are unexplained large deposits into your bank account, gaps in your employment history, and debts you haven't declared on your application. Being upfront about these from the start avoids the lender pausing to ask further questions.

Before issuing a mortgage offer, the lender needs to confirm the property is worth what you're paying for it. There are three main types of valuation, and which one you get depends on the lender, the property, and the loan-to-value.

• Automated valuation model (AVM): an instant, computer-generated estimate based on comparable sales data, usually available the same day.
• Desktop valuation: a surveyor reviews data and photos without visiting, typically 2 to 5 days.
• Physical inspection: a surveyor visits the property in person, typically 5 to 10 days, and more likely for higher-value properties, unusual construction types, or higher loan-to-value applications.

What happens if the valuation comes in low?

A down-valuation is when the surveyor values the property below the price you've agreed with the seller. This can happen for various reasons, including a slowing local market or an overly optimistic asking price. If it happens, you typically have three options: renegotiate the price with the seller, challenge the valuation with supporting evidence, or make up the shortfall with a larger deposit. Whichever route you take, expect it to add 1 to 3 weeks to your timeline, since the lender needs to reassess the application against the new figures.

Once the valuation is back and the underwriter is satisfied, the lender issues a formal mortgage offer. This document sets out the amount being lent, the terms and conditions attached, and any conditions that still need to be met before completion.

How long is a mortgage offer valid for?

Most mortgage offers are valid for 6 months. Some lenders set a shorter window of 3 months, while some new-build lenders extend theirs to 9 to 12 months to account for build delays.

If you're moving home in a chain and your offer looks likely to expire before you complete, contact your advisor or lender as soon as possible. Extension requests are usually possible, but lender policy varies, some will extend with minimal fuss, others require a fresh affordability check or even full re-underwriting, and there can be implications for any arrangement fee you've already paid. The earlier you flag it, the more options you'll have.

Conveyancing is the legal process of transferring ownership of the property, and it runs alongside, and often continues after, your mortgage offer being issued. It covers local authority, drainage and water, and environmental searches, responding to enquiries raised by each side's solicitor, exchange of contracts, and finally completion. Searches alone typically take 2 to 6 weeks, depending on how quickly the local authority responds.

England and Wales vs Scotland

In England and Wales, contracts are exchanged once all searches and enquiries are satisfied, making the transaction legally binding from that point. Scotland works differently, using a system of missives, a series of formal letters between solicitors that become legally binding once concluded. Searches and the sequence of the process differ, so timelines north and south of the border don't always line up.

Your home may be repossessed if you do not keep up repayments on your mortgage or any other debt secured on it, so it's worth understanding your full commitment before you exchange contracts or conclude missives.

Property chains

If you're moving home rather than buying as a first-time buyer, you're likely part of a property chain, a sequence of linked sales and purchases that all need to complete on the same day. Each additional link in the chain adds an estimated 2 to 4 weeks to the overall timeline, and increases the risk that one delayed or collapsed sale holds up everyone else. Our moving home mortgage advice guide covers how to manage a chain from offer to completion.

HM Land Registry processes the majority of straightforward title updates quickly once you've completed, but more complex applications can take considerably longer to register, a separate step from the conveyancing timeline above, though worth being aware of if you're relying on registration for anything time-sensitive.

Most delays come down to a small number of recurring issues. Knowing what they are before you apply gives you the best chance of avoiding them.

If a delay is causing you financial stress, for example because you're paying to hold two properties or a rate reservation is at risk of expiring, free and impartial guidance is available from MoneyHelper on 0800 138 7777.

Using a broker doesn't change how long underwriting or conveyancing takes, but it can reduce the delays that sit within your control. Because we compare a wide range of lenders, your advisor can match your application to a lender whose criteria and processing times suit your circumstances, rather than applying speculatively and finding out weeks later that you don't fit their lending policy.

According to the Intermediary Mortgage Lenders Association, the large majority of UK mortgages are now arranged through brokers rather than directly with lenders, reflecting how much complexity, self-employed income, adverse credit, buy to let, and specialist cases, now sits outside standard high-street criteria. If your credit history is a concern, our guide to adverse credit mortgage options covers how specialist lenders assess applications differently.

Your advisor is regulated by the Financial Conduct Authority and will pre-check your documents before submission, chase your lender and solicitor throughout the process, and flag early if something looks likely to cause a delay. If you're remortgaging rather than moving, timelines look different again, our remortgage timeline and process guide covers what to expect.

The stages above are broadly the same for everyone, but how long each one takes depends heavily on your circumstances. The table below gives a rough guide to what different types of applicant typically experience.
