TL;DR
First-time buyer mortgage in the UK - key points
Buying your first home starts with checking affordability, deposit and expected monthly payments. A first purchase in the UK does not automatically qualify for first-time-buyer tax relief: previous qualifying residential interests overseas, inherited or gifted shares and joint purchasers can affect eligibility. Lender product criteria are separate.
Many first-time buyers start with a 5% deposit, but a larger deposit can improve product choice. A lender will also check income, commitments, credit history, employment type and the property itself.
A broker can compare lenders, arrange an Agreement in Principle, help prepare the application and guide you through the process up to the mortgage offer and completion.
Where should a first-time buyer start?
Checking your budget early helps you focus your property search. Find out how much you may be able to borrow, how much deposit you need and which lender criteria apply to your situation.
1. Check your budget
Income, commitments, dependants, employment type and credit history can all change affordability.
2. Prepare deposit and costs
A deposit is not everything. You also need to plan for solicitor fees, valuation, insurance, moving costs and bills after purchase.
3. Get an AIP
An Agreement in Principle can help show an estate agent that you are prepared to buy, but it does not guarantee a mortgage.
4. Search within a realistic range
With a checked budget, it is easier to compare homes and avoid offers outside your reach.

Mortgage adviser
Do I need to use a mortgage adviser?
You do not have to use an adviser. An adviser can compare mortgage products, prepare the application and explain lender criteria. Ask which lenders they cover, what fees apply and when those fees become payable before deciding whether to use the service.

Deposit, affordability and additional costs
Your deposit has a major impact on the interest rate and maximum mortgage amount. Many lenders require at least 5%, but 10% or more can improve the number of available products. Some no-deposit mortgage options may be available, subject to product-specific eligibility and regional availability.
Example: for a £100,000 property with a £10,000 deposit, the mortgage would be £90,000 — 90% loan-to-value (LTV). This example excludes other purchase costs.
Upfront costs
- legal fees and conveyancing,
- any lender valuation fee, for the lender’s assessment of the property as security,
- a separate buyer’s survey to assess the property’s condition,
- possible broker or lender fee,
- purchase tax: SDLT in England and Northern Ireland, LTT in Wales or LBTT in Scotland, where payable.
Ongoing costs
- council tax in Great Britain (check council tax bands) or domestic rates in Northern Ireland,
- gas and electricity, allowing for the home’s energy use and your tariff,
- water, home insurance, TV licence and a buffer for initial repairs.
Stamp Duty Land Tax (SDLT) applies in England and Northern Ireland, Land Transaction Tax (LTT) in Wales and Land and Buildings Transaction Tax (LBTT) in Scotland. Eligible first-time buyers may receive SDLT or LBTT relief, which can reduce tax without eliminating it; Wales has no specific first-time-buyer relief. For SDLT, previous qualifying residential interests anywhere in the world, including inherited or gifted shares, can disqualify you, and all joint purchasers must qualify. Ask your solicitor or conveyancer to check the rules for your purchase. More context is available in: First Time Buyer in the UK - how it works.
How much can I borrow?
It depends on income, employment type, outgoings, credit history, commitments, dependants and deposit. An affordability check can help you set a realistic buying budget.

What to avoid
Common first-time buyer mistakes
Viewing homes without a checked budget
Checking your budget early helps you focus on homes within reach and avoid committing to an unaffordable purchase.
Making an offer without an AIP
An Agreement in Principle does not guarantee a mortgage, but it shows the seller that you are prepared and have been checked at an initial stage.
Looking only at the interest rate
The lowest rate is not always the best option. Fees, total cost, lender criteria and product flexibility also matter.
Leaving no money after completion
Keep a buffer for council tax in Great Britain or domestic rates in Northern Ireland, insurance, bills and initial repairs. Avoid using every pound of savings for the deposit.
FAQ
Frequently asked questions
How much deposit does a first-time buyer need in the UK?
Many first-time buyers start with a 5% deposit. A 10% deposit or more can increase the number of available products and may improve the rate. The exact options depend on your income, commitments, credit history, property type and lender criteria.
Does an Agreement in Principle guarantee a mortgage?
No. An Agreement in Principle is an initial indication based on basic information. The lender will still check documents, income, outgoings, credit history and the property before issuing a full mortgage offer.
Do I need a mortgage adviser as a first-time buyer?
You do not have to use one, but it is often useful. A mortgage adviser can check affordability, compare lenders, explain costs and guide you through the application. For a first purchase, this can help avoid mistakes and unnecessary stress.
What extra costs should I plan for when buying my first home?
Alongside the deposit, budget for legal fees, any lender valuation fee, a separate survey to assess the property’s condition, possible lender or broker fees, moving and insurance. Purchase tax depends on location: Stamp Duty Land Tax (SDLT) in England and Northern Ireland, Land Transaction Tax (LTT) in Wales or Land and Buildings Transaction Tax (LBTT) in Scotland. Eligible first-time buyers may receive SDLT or LBTT relief, which can reduce tax without eliminating it; Wales has no specific first-time-buyer relief. Ongoing costs include council tax in Great Britain or domestic rates in Northern Ireland, plus household bills.
Does buying my first home in the UK make me a first-time buyer for tax relief?
Not automatically: buying your first home in the UK is different from qualifying for first-time-buyer tax relief. For SDLT in England and Northern Ireland, previous qualifying residential interests anywhere in the world, including inherited or gifted shares, can disqualify you, and all joint purchasers must qualify. Scotland has its own LBTT relief rules; Wales has no specific first-time-buyer relief. Ask your solicitor or conveyancer to check your position; mortgage lenders use separate product criteria.
Can I buy my first home with adverse credit?
Sometimes, but it depends on the type of issue, amount, dates and your current situation. Minor older late payments are different from recent missed payments, defaults or CCJs. Check your credit report before applying.
