TL;DR

First-time buyer mortgage in the UK - key points

A first-time buyer is someone buying their first property. In the UK, the safest place to start is checking affordability, deposit and expected monthly payment before arranging serious viewings.

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?

The biggest mistake is starting with property viewings before the budget is checked. First, find out how much you may be able to borrow, how much deposit you need and whether a lender is likely to accept 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.

4. Search within a realistic range

With a checked budget, it is easier to compare homes and avoid offers outside your reach.

The process is easier when it is broken into clear stages. You know what happens now, what comes next and where costs or documents may appear.

Mortgage adviser

Do I need to use a mortgage adviser?

You do not have to, but it is often useful for a first purchase. A mortgage adviser can compare products, prepare the application and explain the differences between lenders. The fee can be outweighed by better fit, fewer mistakes and a smoother process.

Over 2,500 products

You do not need to compare dozens of lenders, fees and criteria by yourself.

Less stress

You know what is happening at each stage and which documents are needed.

Better fit

We check products against your income, deposit, credit history and plans.

Clear UK mortgage guidance

We explain the process in plain English, without unnecessary lender jargon.

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 exist, depending on criteria.

Example: if the property costs GBP 100,000 and you have GBP 10,000 deposit, you need a mortgage for 90% of the property value. You can also read more in: Buying a home without a deposit.

Upfront costs

  • legal fees and conveyancing,
  • valuation or home survey,
  • possible broker or lender fee,
  • Stamp Duty Land Tax, if relief does not apply.

Ongoing costs

  • Council tax, depending on area and property band,
  • gas and electricity, which you can compare using guidance from British Gas,
  • water, home insurance, TV licence and a buffer for initial repairs.

As a first-time buyer, you may qualify for Stamp Duty Land Tax relief depending on current rules and property price. More context is available in: First Time Buyer in the UK - how it works.

Documents and keys during a first home purchase
A good buying plan connects deposit, costs, documents and the right mortgage product.

How much can I borrow?

It depends on income, employment type, outgoings, credit history, commitments, dependants and deposit. That is why an affordability check should come before serious property viewings.

What to avoid

Common first-time buyer mistakes

1

Viewing homes without a checked budget

First check whether your realistic budget is, for example, GBP 220,000, GBP 260,000 or GBP 300,000. Otherwise it is easy to fall in love with a property outside your range.

2

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.

3

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.

4

Leaving no money after completion

After buying, you may need to pay council tax, insurance, bills and first repairs. It is rarely sensible to use every pound of savings only 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, plan for legal fees, valuation or survey, possible lender fees, broker fee, moving costs, home insurance, council tax and household bills. Depending on the property price and rules at the time, Stamp Duty Land Tax may also apply.

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.

Your Home (or property) may be repossessed if you do not keep up repayments on your mortgage or any other debts secured on it. Conveyancing services are not regulated by the Financial Conduct Authority.
