Frequently Asked Questions

How long does a mortgage application take in 2025?

A typical UK mortgage application takes 3-6 weeks from submission to receiving your mortgage offer. Straightforward cases (employed, good credit, complete documentation) can be approved in 2-3 weeks. Complex cases (self-employed, adverse credit, high LTV) typically take 5-8 weeks. The timeline breaks down as: Week 1 - initial assessment and credit check, Week 2 - income verification and affordability calculations, Week 3 - property valuation, Week 4-6 - underwriter review and offer issuance. Peak times (March-August) can add 1-2 weeks. To speed up your application: submit complete documentation first time, respond quickly to lender requests, maintain stable income patterns, and avoid new credit applications during the process. Use our affordability calculator to prepare before applying.

What credit score do I need for a mortgage?

Most UK lenders require a minimum credit score of 620-650 (Experian scale 0-999) for standard mortgage approval. Scores of 700+ are considered good and qualify for best rates. Scores of 750+ are excellent and access the widest range of products. Scores of 580-620 may still qualify with specialist lenders but expect higher interest rates (0.5-2% premium) and larger deposit requirements (15-25% instead of 5-10%). Scores below 580 are considered poor - you'll need specialist bad credit lenders, 25-40% deposits, and rates 2-4% above prime. Each lender uses different scoring models, so one rejection doesn't mean all will reject. Key factors affecting mortgage credit scores: payment history (35%), credit utilization (30%), length of credit history (15%), types of credit (10%), recent applications (10%). Improve your score by: paying all bills on time for 6+ months, reducing credit card balances below 30% of limits, registering on electoral roll, correcting errors on credit reports. Check our adverse credit guide for detailed strategies.

Can I get a mortgage if I'm self-employed?

Yes, self-employed individuals can absolutely get mortgages, but the process is more complex and requires additional documentation. You'll typically need: 2-3 years' trading history (some specialist lenders accept 1 year), SA302 tax calculations and tax year overviews from HMRC, certified accounts if you're a limited company, 12 months' business and personal bank statements, and an accountant reference letter. Lenders calculate your income by averaging the last 2-3 years (some use the lowest year to be conservative). They consider: salary, dividends, net profit (sole traders), and sometimes retained profits. Challenges: income fluctuations make affordability harder to prove, lenders are more cautious with self-employed applicants, you may get lower income multiples (4x instead of 4.5x), and you'll need larger deposits (15-20% vs 5-10%). Success tips: maintain consistent income for 2+ years, keep detailed accounts, use a specialist mortgage broker, prepare comprehensive documentation, and allow 6-8 weeks for the application process. Self-employed applicants have 85-90% approval rates vs 95%+ for employed applicants. Check our deposit calculator to plan your application.

What happens if my mortgage application is rejected?

If your mortgage application is rejected, you have several options: (1) Understand the reason: Lenders must explain why - common reasons include insufficient income, poor credit score, high debt-to-income ratio, property valuation issues, or incomplete documentation, (2) Address the issues: Improve credit score (6-12 months), increase deposit, reduce existing debts, or wait for income to stabilize, (3) Try different lenders: Each lender has different criteria - one rejection doesn't mean all will reject, (4) Use a mortgage broker: Brokers know which lenders accept specific circumstances and can improve success rates by 30-40%, (5) Consider specialist lenders: Higher rates but more flexible criteria for complex cases. Important: Multiple applications in short time damage your credit score (each hard search reduces score by 5-10 points). Wait 1-3 months between applications and use a broker to avoid multiple searches. Rejection rates: 15-20% of first applications are rejected, but 70% of these are approved on second attempt after addressing issues. Don't give up - most rejections are fixable with time and preparation.

Do I need a mortgage broker or can I apply directly?

You can apply directly to lenders, but mortgage brokers offer significant advantages, especially for complex cases. Apply directly if: You have excellent credit (750+), straightforward employed income, 15%+ deposit, simple property purchase, and time to research products yourself. Use a broker if: You're self-employed, have any credit issues, need high LTV (90-95%), buying unusual property, or want access to whole market. Broker benefits: Access to 90+ lenders vs 1 lender direct, expert knowledge of lending criteria, handle all paperwork and communication, often get better rates through volume relationships, save 20-40 hours of research time, improve approval chances by 30-40% for complex cases. Broker costs: Many are free (paid by lender commission), some charge £500-£1,500 fee, avoid brokers charging >£2,000 or percentage fees. Statistics: 70% of UK mortgages are arranged through brokers, broker applications have 92% approval rate vs 85% for direct applications, brokers save average £1,200 over mortgage term through better rates. Recommendation: Use a broker for first mortgage, complex income, or credit issues. Apply direct only if very straightforward case and you enjoy research.

How many payslips do I need for a mortgage?

Most UK lenders require 3 months' recent payslips for employed applicants, though some accept 2 months for very straightforward cases. The payslips must: show your full name and employer name, display gross salary, net salary, and all deductions (tax, NI, pension), be consecutive months (no gaps), and be dated within the last 3 months at application time. Additional requirements: P60 from most recent tax year (proves annual income), employment contract or offer letter (if in probation or new job), 2 years' payslips if claiming bonus/commission as income (to prove consistency). Special cases: If you've just started a new job, you may need: offer letter stating salary and start date, first payslip when received, explanation letter from employer, and some lenders require 3-6 months in role before approving. Self-employed: Don't use payslips - need SA302 tax calculations and accounts instead. Pro tip: Get fresh payslips just before applying - payslips older than 3 months may be rejected, requiring you to restart the process. Keep digital and physical copies of all payslips for easy access.

What is a mortgage Agreement in Principle (AIP)?

A mortgage Agreement in Principle (AIP), also called Decision in Principle (DIP) or mortgage promise, is a conditional statement from a lender indicating how much they'd be willing to lend you based on initial information. What it includes: Maximum loan amount, estimated interest rate, validity period (usually 60-90 days), and conditions that must be met. How to get one: Provide basic information (income, expenses, deposit, credit history), soft credit check performed (doesn't affect credit score), issued within minutes to 48 hours, and free from most lenders and brokers. Benefits: Shows sellers you're a serious buyer, helps you house hunt within budget, speeds up full application (some checks already done), and identifies potential issues early. Important notes: NOT a guarantee - full application can still be rejected, doesn't commit you to that lender, property-specific factors not yet considered, and income/credit must be verified in full application. Validity: Typically 60-90 days, can be renewed if house hunting takes longer. Recommendation: Get AIP before house hunting - 85% of sellers prefer buyers with AIP, and it can speed up offer acceptance by 2-3 weeks. Multiple AIPs don't harm credit if using soft searches.

Can I get a mortgage with a zero-hour contract?

Yes, but it's more challenging and requires proving income stability. Lenders view zero-hour contracts as higher risk due to income uncertainty. Requirements: Minimum 12 months in current role (some lenders require 24 months), consistent income pattern over that period, average income calculated over 12-24 months, and often need larger deposit (15-20% vs 5-10%). Documentation needed: 12-24 months' payslips showing regular work, 12 months' bank statements proving consistent income deposits, employment contract confirming zero-hour status, and employer letter confirming ongoing work availability. Income calculation: Lenders average your income over 12-24 months, exclude one-off peaks to find sustainable income, and may apply 10-20% reduction for uncertainty. Example: If you earned £30k, £28k, £32k over 3 years, lender might use £28k (lowest) or £30k (average) minus 10% = £27k for affordability. Improving chances: Build 2+ years' consistent income history, maintain same employer, supplement with guaranteed hours if possible, use specialist broker familiar with zero-hour contract mortgages, and consider joint application with partner on permanent contract. Success rate: 60-70% for zero-hour contracts vs 95% for permanent contracts. Specialist lenders more flexible but charge 0.5-1.5% higher rates.
