Of the 40,925 residential sales recorded in Wales during 2025, 83.1% were priced at £350,000 or below — the exact price at which Wales's Land Transaction Tax (LTT) stops being cheaper than England's Stamp Duty Land Tax (SDLT) and starts costing more. Below that line, a Welsh buyer's tax bill is lower, or identical, to what the same purchase would cost in England. Above it, Wales becomes the more expensive nation, and the gap widens the higher the price climbs.
That £350,000 figure isn't a Welsh policy threshold — Land Transaction Tax's own nil-rate band ends at £225,000, and its bands don't otherwise line up with SDLT's. It's a coincidence of two independently-set rate schedules that happens to produce one price where the totals match to the penny.
Why £350,000 is the crossover point
Land Transaction Tax and Stamp Duty Land Tax are calculated on completely different band structures. LTT's nil-rate band runs to £225,000 — £100,000 higher than SDLT's £125,000 — but LTT's next band then charges 6%, above SDLT's 2%. That combination means Wales starts cheaper and stays cheaper for a stretch, then SDLT overtakes it.

The same crossover holds for buyers of a second home or rental property. Both nations apply a flat 5-percentage-point surcharge on top of the standard schedule, and because it's added at the same rate across every band in both systems, it doesn't move the point where the totals meet — it just scales both sides up by the same proportion. A landlord buying at £350,000 pays £25,000 in either country; a penny either side, the ranking flips exactly as it does for a standard mover.
Where Wales's 2025 market actually sits
The £350,000 line only matters in practice if buyers are actually transacting near it. Land Registry data for 2025 shows most aren't — Welsh sales are heavily concentrated well below the crossover.
| Price band | Welsh sales (2025) | Share of Wales | Share of England |
|---|---|---|---|
| Up to £225,000 (LTT nil-rate) | 21,917 | 53.6% | 30.5% |
| £225,001 – £350,000 | 12,098 | 29.6% | 30.2% |
| Above £350,000 | 6,910 | 16.9% | 39.4% |
| Total | 40,925 | 100% | 100% |
Category-A (standard residential, arm's-length) sales, 2025, HM Land Registry Price Paid Data via Homecost, fetched 2026-09-11. England figures use the same three price bands for comparison, from 758,160 category-A sales.
More than half of all Welsh sales (53.6%) fell inside LTT's own nil-rate band and attracted no Land Transaction Tax at all — a considerably larger share than the 30.5% of English sales that clear no SDLT, reflecting Wales's generally lower price level rather than a more generous threshold (LTT's nil-rate band, at £225,000, is actually £100,000 above SDLT's £125,000, but England's higher average prices push a smaller share of sales under either line). The median Welsh sale in 2025 was £217,500 — itself just below the nil-rate band.
Only 16.9% of Welsh transactions sat above £350,000, the point where the Land Transaction Tax bill overtakes what the equivalent English purchase would cost. By contrast, 39.4% of English sales were above that same price — England's market is weighted much more heavily into the price range where, coincidentally, Wales would be the costlier place to buy the same house.
What this means in practice
For the typical Welsh buyer, the tax comparison with England is favourable or neutral. Only a minority — fewer than one in five 2025 Welsh sales — sit in the price bracket where an equivalent purchase would attract more tax in Wales than in England. That minority is concentrated in higher-value sales: city-centre Cardiff and Cardiff-fringe properties, larger family homes, and rural detached houses are the most likely to cross £350,000, while the mid-priced terraces and semis that make up most of the Welsh market sit comfortably on the cheaper side of the line.
One structural difference is worth flagging: Wales operates no first-time buyer relief. England's SDLT gives first-time buyers a larger nil-rate band (up to £300,000) and a reduced rate up to £500,000, which changes the England-side numbers in the table above for that specific group of buyers — a first-time buyer's England/Wales crossover sits at a different price than a home mover's. The comparison here applies to standard movers and additional-property buyers, where both nations use the same basic band mechanics.
