First-Time Buyer Mortgages in the UK
Buying your first home is one of the biggest financial steps you’ll take. This guide covers what UK lenders look at, the deposit options available, and the schemes that may help.
Your home may be repossessed if you do not keep up repayments on your mortgage.
This page is for buyers preparing for a first residential mortgage in the UK.
Quick summary
- Most lenders need a minimum 5% deposit, but 10–15% unlocks much better rates.
- Government-backed options include the Mortgage Guarantee Scheme and the Lifetime ISA.
- Affordability assessments are typically 4× to 4.75× combined income, less commitments.
- A credit footprint of 3–6 months helps — being on the electoral roll, settled at one address, etc.
- A mortgage agreement in principle (AIP) is usually required before estate agents take offers seriously.
What lenders may look at
- Combined income
- Deposit size and source (savings, gift, LISA)
- Credit history and active commitments
- Employment stability
- Property type and construction

- 2 years SA302s + tax year overviews (self-employed)

Practical next steps

- Check that deposit funds can be evidenced and any gifted deposit is documented.
- Review credit files and regular commitments before a lender application.
- Consider an agreement in principle once your budget and documents are ready.
Common issues
- Deposit smaller than 10% — many lenders cap LTV at 90% on flats, ex-local-authority and new build.
- Recent job change inside probation — most lenders prefer 3+ months past probation.
- Thin credit file — start building one well before applying.
- Spending patterns showing payday loans or persistent overdraft — lenders look at the last 3 months of bank statements.
Frequently asked questions
How much deposit do I need as a first-time buyer? +
Most UK lenders accept 5% but rates improve materially at 10% and again at 15–25%. Some lenders cap higher LTV products on new build or flats.
Does Help to Buy still exist? +
The Help to Buy equity loan scheme in England closed to new applications in October 2022. Shared Ownership and the Mortgage Guarantee Scheme remain available.
Can I use a gifted deposit? +
Yes. Most lenders accept gifted deposits from immediate family with a signed gift letter confirming the funds are non-refundable and the gifter has no interest in the property.
What credit score do I need? +
There’s no single threshold — UK lenders score applicants on their own internal model. A clean payment history for 12 months and being on the electoral roll helps.
How long does the process take? +
4–8 weeks from offer accepted to mortgage offer is typical. Allow another 4–6 weeks for completion if there is a chain.
