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.

If your purchase included moveable items — carpets, curtains, freestanding appliances, garden furniture — their value should have been deducted from the SDLT calculation. Most solicitors skip this step. HMRC allows refund claims for up to four years after completion.

What is the stamp duty on a £1,000,000 second home?
