The surcharge that catches people out

If you will still own another residential property worth £40,000 or more anywhere in the world after you buy, the additional property surcharge usually applies. On the £1,800,000 benchmark that adds £90,000, taking the bill to £219,750.

It catches people mid move, when the old home has not sold. You can usually reclaim the surcharge if you sell the previous main residence within the time limit. Budget for it anyway.

Where it sits in your cash pile

Stamp duty of £129,750 sits alongside a 10% deposit of £180,000 and legal and survey fees. Together that is roughly £312,250 before you own anything.

Rates are those in force from April 2025. Thresholds change with fiscal events, so confirm the current position on gov.uk before you exchange.

By price, Chelsea ranks 7 of the 320 London locations we cover, at £1,800,000 against a county average of £732,469. Band D council tax here is £1,643, against an average of £2,121 across the towns we cover in the county.

Local prices sit above the first time buyer relief ceiling of £500,000, so relief will not help on a typical purchase here. That is a real disadvantage for first buyers in this area.
