The UK mortgage process — from initial application to receiving your keys — typically takes 8 to 12 weeks. This includes the lender's underwriting and valuation (2–6 weeks) and the legal conveyancing process (6–10 weeks running in parallel).
The Mortgage Timeline at a Glance

| Property search & viewings | Varies (weeks to months) |
| Offer accepted → full application | 1–3 days |
| Lender processing & valuation | 1–3 weeks |
| Mortgage offer issued | 2–6 weeks from application |
| Conveyancing & searches | 6–10 weeks |
| Exchange of contracts | 8–12 weeks from offer accepted |
| Completion (keys!) | 1–2 weeks after exchange |
Stage 1: Agreement in Principle
An AIP (also called a Decision in Principle) is a preliminary check that confirms how much a lender is willing to offer you. Through a broker, this can take minutes to 48 hours.
We recommend getting an AIP before you start house hunting. It shows estate agents and sellers you're serious, and it sets your budget.
Stage 2: Full Mortgage Application
Once your offer is accepted, your broker submits a full application to the lender. To avoid delays, have these documents ready:
- Last 3 months' payslips (or 2–3 years' accounts/SA302s if self-employed)
- Last 3 months' bank statements
- Proof of ID (passport or driving licence)
- Proof of address (utility bill dated within 3 months)
- Proof of deposit (savings statements or gift letter)
The lender reviews your application and arranges a property valuation. This stage typically takes 2–4 weeks. Budget for all associated mortgage fees at this stage.
Common Causes of Delays
- Incomplete documentation: The single biggest cause of delays. Missing payslips or bank statements can add weeks.
- Property chains: Each link in the chain can cause delays if any party has problems.
- Slow solicitors: Conveyancing quality varies enormously. Choose a responsive solicitor.
- Search delays: Local authority searches can take 2–6 weeks depending on the council.
- Valuation issues: If the surveyor values the property lower than the purchase price (a "down valuation"), renegotiation is needed.
- Credit issues: Undisclosed debts or credit problems that surface during the application.
How to Speed Up the Process
- Use a broker: A fee-free broker knows which lenders are processing fastest and can chase progress on your behalf.
- Have documents ready: Gather everything before you make an offer.
- Choose a good solicitor: Ask for recommendations and check reviews. A proactive solicitor makes a huge difference.
- Respond quickly: When your solicitor or lender asks for information, respond the same day.
- Keep the chain short: If possible, buy chain-free properties (new builds, probate sales, empty properties).
