Cost to buy a £300,000 house in the UK

This page gives a quick £300,000 buying-cost estimate for buyers who want the deposit, extra fees and likely total cash target in one place.

Direct answer

The total cost to buy a £300,000 house in the UK is the deposit plus all upfront costs needed to complete the purchase. A buyer using a 10% deposit would need around £30,000 for the deposit, plus several thousand pounds more for legal fees, surveys, mortgage costs, moving and setup.

Typical cost breakdown for a £300,000 house

  • 10% deposit: £30,000
  • Stamp duty or property tax: £0–£7,500 depending on buyer type
  • Legal fees: ~£800–£1,800
  • Surveys: £300–£1,000+
  • Mortgage fees: £0–£2,000+
  • Moving and setup costs: £500–£2,500+

Practical note

Deposit, property tax, legal fees, surveys, mortgage costs and moving and setup are the main lines buyers usually need to cover.

Typical total upfront cash needed

Typical total upfront cash needed for a £300,000 house:

£34,000–£48,000+ depending on buyer type, location and assumptions.

Most buyers should expect their deposit plus £4,000 to £18,000+ in additional upfront costs.

Why the total cost can vary

At £300,000, the buyer type can swing the total more than many people expect. A first-time buyer may face a much lighter tax line than a home mover or additional-property buyer, so the same headline price can lead to a very different cash target.

SDLT, LBTT and LTT also create different outcomes across the UK. Survey choice, property condition, mortgage fees and moving costs then add another layer, which is why a £300,000 purchase should be treated as a full budget exercise rather than a deposit-only target.

Try your own £300,000 scenario

Use the calculator to test a £300,000 purchase with your own deposit, buyer type and location instead of relying on one fixed estimate.

After completion, some buyers also look at whether overpaying their mortgage could reduce interest over time, but that should only come after the purchase costs and emergency buffer are covered.

FAQ

Questions buyers usually ask

How much deposit do I need for a £300,000 house?

A 10% deposit is £30,000. A 5% deposit would be £15,000, a 15% deposit would be £45,000, and a 20% deposit would be £60,000, so the right target depends on mortgage options and how much cash you still need for fees.

What are the extra costs beyond the deposit?

The extra costs usually include legal fees, surveys, mortgage costs, property tax where it applies, and moving and setup spending. Buyers should treat those separately from the deposit rather than assuming they will stay small.

Do first-time buyers pay stamp duty on a £300,000 house?

That depends on the nation, the current rules and the buyer's exact situation. First-time buyers may face a lighter tax position than home movers or additional-property buyers, but SDLT, LBTT and LTT do not all work the same way.

How much savings should I have in total?

A practical planning target is about £34,000–£48,000+ in total upfront cash on a £300,000 purchase, depending on buyer type, location and assumptions. That range is a planning estimate, not a guaranteed quote.
