Worked examples (home mover, typical fees)
How first-time buyer relief works at £450,000
In England, first-time buyer relief gives a 0% rate on the first £425,000 and 5% on the amount from £425,001 to £500,000. At £450,000, that means 0% on £425,000 and 5% on £25,000.
This is materially lower than the standard residential rate at the same price. The relief still saves first-time buyers a significant sum compared with paying standard rates on the full amount.
For eligibility, both buyers must be first-time buyers when purchasing jointly. One previous homeowner in the purchase removes the relief entirely, making it standard rate on the full £450,000.
Standard and second-home scenarios at £450,000
Standard residential SDLT on £450,000 applies at 0% on the first £125,000, 2% on £125,000–£250,000, and 5% on £250,000–£450,000. The calculator gives the exact figure.
Second home and buy-to-let buyers pay the additional dwelling supplement on top of standard rates, which creates a large uplift in total stamp duty at this price level.

The £425,000 and £500,000 thresholds in context
£450,000 sits between the two key first-time buyer thresholds: above the full 0% ceiling (£425,000) but within the upper relief limit (£500,000).
If a negotiation could bring the price below £425,000, a first-time buyer would save the 5% on the £25,000 overage — a modest but real difference.
Above £500,000, first-time buyer relief disappears entirely and standard rates apply on the full amount, so crossing that ceiling would cost significantly more in SDLT.
Decision framework used by careful buyers
Start with an offer ceiling based on total cash, not headline house price. In practice, buyers who only track deposit and mortgage payments can miss the transaction-cost layer, which is exactly where completions become stressful.
Use a three-pass approach: first estimate tax by nation and buyer type, then add realistic fees, then pressure-test the result by increasing the offer by £10,000 and £25,000. This shows how sensitive your budget is before bidding.
Treat the model as a planning instrument. Final legal liability always sits with official calculators and your conveyancer’s completion statement, but early visibility reduces avoidable surprises.
Practical checklist before making an offer
Confirm your likely buyer status first (home mover, first-time buyer, or additional property). Switching status can alter tax materially at the same price point, so this should be fixed before negotiating.
Collect at least two conveyancing quotes and check what is included. Buyers often compare legal fees without checking disbursements, search packages, leasehold supplements or transfer fees.
Keep a contingency buffer instead of budgeting to the exact minimum. A modest reserve can protect timelines when valuation, legal or lender admin costs move late in the process.
