Stamp duty (Land Transaction Tax) in Swansea
Every Swansea average except two sits below the £225,000 Welsh nil band, so the higher rates are the tax that matters here.
Checked by Radif Partners · Editorial policy · How we calculate
The average home in Swansea sold for £205,383 in July 2026, according to the UK House Price Index, below the £225,000 nil band of the Welsh main rates, so a buyer who will own only that home pays £0 of Land Transaction Tax. The same is true of the city’s average flat (£109,080), terrace (£169,318) and semi-detached house (£210,464), and of the £177,161 paid on average by first-time buyers, who need no relief to pay nothing. Home movers paid £246,436 and pay £1,286. A buyer who keeps another home is in a different position: the Welsh higher rates start at 5% on the first pound, so the city average costs £11,157 as a second home or rental, and the average flat £5,454.

Prices in the city moved -0.2% over the year to July 2026. Because the main-rate bill is zero across most of the market, a change in price affects only buyers above £225,000 and those paying the higher rates, whose bill moves by 5% to 10% of every pound.
Holiday lets and second homes
A holiday cottage on the Gower or a flat by the marina bought by someone who keeps their main home pays the higher rates on the whole price, from a separate band table. Companies pay them on every purchase. Since 11 December 2024 the table starts at 5%, up from 4% before; the higher rates page sets out both tables, and the refund page explains when they come back.
