Stamp Duty on a £1,000,000 House
A £1,000,000 purchase generates a £43,750 stamp duty bill at current 2025 rates. At this price point, the 10% rate kicks in on the portion above £925,000. A professional chattels valuation on a property of this size can deliver savings of £2,500–£5,000 — making it well worth investigating before (or up to four years after) completion.

How much stamp duty do I pay on a £1,000,000 house?
Buyers pay £43,750: 0% on the first £125,000 (£0), 2% on the next £125,000 (£2,500), 5% on £675,000 from £250,001 to £925,000 (£33,750), and 10% on the remaining £75,000 (£7,500).
Why is the stamp duty rate higher on a £1 million house?
The 10% band kicks in on the portion of the purchase price above £925,000. On a £1,000,000 purchase, £75,000 falls into this band.
What is the stamp duty on a £1,000,000 second home?
A second home or buy-to-let at £1,000,000 attracts £73,750 — the 3% surcharge is added to each band.
Is a chattels survey worth commissioning on a £1 million property?
Almost certainly. A furnished property at this price point routinely contains £50,000–£100,000 of chattels. A RICS-backed chattels schedule costs £300–£600 but can deliver a stamp duty saving of £2,500–£5,000 or more.
