A mortgage application usually takes two to six weeks from submitting your full application to receiving a formal mortgage offer. Well-prepared applications submitted through a broker are regularly approved in under two weeks, and the quickest lenders in 2026 are issuing offers in as little as a week. In this guide, we’ll walk through every stage of the timeline, what can slow things down, and how to keep your application moving.
An agreement in principle takes minutes to 48 hours and typically lasts 60-90 days.
Full application to formal offer averages 2-6 weeks - often under two weeks through a broker.
Lender choice matters: in 2026 the fastest lenders average 6-8 days to offer, the slowest around 20.
Incomplete paperwork is the single biggest cause of mortgage delays.
Once issued, your mortgage offer usually lasts six months.

What Are the Stages of a Mortgage Application?
Every mortgage application follows the same four stages, whether you’re a first-time buyer or a home mover:
- Agreement in principle (AIP) – a quick affordability check, done in minutes to 48 hours.
- Full application and underwriting – usually one to four weeks, depending on the lender and your circumstances.
- Property valuation – booked within one to two weeks, often running alongside underwriting.
- Formal mortgage offer – typically issued within a week of a successful valuation.
After your offer is issued, the legal work (conveyancing) continues separately and usually takes another 8-12 weeks to reach completion – but your mortgage itself is agreed long before then.
How Long Does an Agreement in Principle Take?
An agreement in principle usually takes minutes to 48 hours. It’s based on a soft credit check, so it won’t affect your credit score, and it tells you roughly how much you could borrow. Most estate agents will expect you to have one before taking your offer seriously, and it typically lasts 60-90 days.
How Long From Full Application to Mortgage Offer?
This is the stage most people mean when they ask how long a mortgage takes. Going directly to a lender, the typical range in 2026 is two to six weeks. Industry analysis of broker-submitted applications this year shows an average of around 11 days from full application to formal offer – and the gap between lenders is currently the widest it has been in five years. The fastest lenders are averaging 6-8 days, while the slowest major lenders take around 20 days for a comparable case.
The difference rarely comes down to luck. Fast approvals come from complete documents up front, a straightforward income picture, and applying to a lender whose criteria you clearly meet.

How Long Does the Mortgage Valuation Take?
The lender’s valuation is usually booked within one to two weeks of your full application. Many lenders now use automated or desktop valuations for straightforward properties, which can come back within days. If the surveyor values the property below your agreed price (a down-valuation), you may need to renegotiate with the seller, which adds time.
How Long Does a Mortgage Offer Last?
Once issued, a mortgage offer typically lasts six months (around three months for remortgages). That’s your window to complete the purchase. If you’re buying a new build with a longer completion date, it’s worth choosing a lender that offers extensions – something we factor in when recommending one.
Why Is My Mortgage Application Taking So Long?
If your application has stalled, it’s almost always one of these:
- Incomplete or inconsistent paperwork – the biggest culprit by far. Missing payslips, unexplained deposits or mismatched addresses all trigger extra queries.
- Complex income, such as self-employment, contracting or bonus-heavy pay – lenders ask for more evidence. We specialise in these cases, including self-employed applicants with as little as one year of accounts.
- Valuation hold-ups, from surveyor availability to a down-valuation.
- Busy lender periods – when a lender launches a market-leading rate, service levels often slip.
- Slow responses – every day a lender waits for a document adds a day to your timeline.
How Can I Speed Up My Mortgage Application?
Preparation makes the biggest difference. Before you apply, gather three months’ payslips and bank statements, proof of ID and address, and evidence of your deposit. Keep the details on your application consistent with your documents, respond to any lender query the same day, and make sure you’re on the electoral roll. Above all, apply to a lender whose criteria you actually meet – a declined application can cost you weeks.
Should I Speak to a Mortgage Broker?
You can apply directly to a lender, but a broker will usually save you both time and stress. We know each lender’s current service levels, we package applications so they pass underwriting first time, and we chase progress through dedicated broker channels. That’s a big part of why broker-submitted applications are currently averaging under two weeks to offer, against four to six weeks for many direct applications.
