Buy a hectare of bare development land for £900,000 and the stamp duty comes to about £34,500. Buy a £900,000 house on the same day and a home mover pays £35,000 — barely any different. Push both to £1.5 million, though, and the land bill is £29,250 lower. The reason is not a loophole: bare land carries no dwelling, so it is non-residential, and non-residential property is taxed on a flatter Stamp Duty Land Tax (SDLT) scale than homes are.
That distinction matters most to the developers and investors who tie up sites through options — contracts that lock in a price while planning permission is pursued. This guide sets out the non-residential SDLT scale, works a full option chain through it, and shows exactly where the non-residential bill parts company from the residential one.
Why development land is "non-residential"
SDLT sorts every purchase into one of two rate tables. Residential covers a dwelling — or land that forms part of a dwelling's garden or grounds. Non-residential covers everything else: commercial premises, agricultural land, and bare development land with no building on it. Where a single purchase includes both a dwelling and non-residential land, the whole price is charged on the non-residential table (a "mixed-use" transaction).
Whether a plot is residential or non-residential is a question of fact judged at the moment of completion — not a label a buyer picks. Bare land that has never held a home, a field earmarked for housing, or a cleared brownfield site is non-residential because, on completion day, there is no dwelling on it. Where a run-down building blurs the line, the classification is heavily contested — a separate question we cover in mixed-use disputes over a house with land.
The non-residential SDLT scale
The non-residential freehold scale for England and Northern Ireland has just three slabs, unchanged since 2016:
| Slice of the price | Rate |
|---|---|
| Up to £150,000 | 0% |
| £150,001 to £250,000 | 2% |
| Above £250,000 | 5% |
Two features drive everything that follows. First, the top rate is a flat 5% — there is no 10% or 12% band, however high the price climbs. Second, the non-residential scale carries no additional-property surcharge and no non-resident surcharge — the 5% and 2% add-ons that load the residential bill for second homes, buy-to-let and overseas buyers simply do not exist here.
A worked development-land option chain
An option can generate SDLT at up to three points, and each is charged on the non-residential scale when the underlying asset is bare land. Take a typical chain:
| Step | Who acquires | Consideration | Non-residential SDLT |
|---|---|---|---|
| Grant | Developer A takes an option from the landowner | £50,000 premium | £0 |
| Assignment | Investor B buys the option from A | £120,000 | £0 |
| Exercise | B completes the land purchase | £900,000 | £34,500 |
The grant of an option is itself a land transaction, charged on the premium paid for it; the assignment is a further transaction, charged on what B pays A for the option; and the exercise is the land purchase itself. Here the £50,000 premium and the £120,000 assignment price both sit below the £150,000 nil-rate band, so no tax arises on either — the substantive charge, £34,500, lands only on exercise.
Who bears each charge, and when, is a story in its own right: the aggregation rule that can catch an option's original holder does not automatically follow the option into an unconnected buyer's hands. We walk that through in trading a property option: who pays, and when, and the underlying grant-and-exercise mechanics in options and pre-emption rights under section 46.
At £900,000 the non-residential exercise bill of £34,500 sits just £500 below the £35,000 a home mover would pay on the residential scale at the same price. Below the top of the market that £500 gap is constant — and then it changes sharply.
Where the two scales diverge: the £925,000 line
Set the two scales side by side and a clear pattern appears. From £150,000 up to £925,000 the non-residential bill is a flat £500 cheaper than the standard residential bill, no matter the price. Above £925,000 — the point where the residential scale steps up to 10%, and then to 12% above £1.5 million — the flat 5% non-residential ceiling pulls away fast:
| Price | Residential (home mover) | Non-residential / land | Difference |
|---|---|---|---|
| £250,000 | £2,500 | £2,000 | £500 |
| £500,000 | £15,000 | £14,500 | £500 |
| £750,000 | £27,500 | £27,000 | £500 |
| £900,000 | £35,000 | £34,500 | £500 |
| £1,000,000 | £43,750 | £39,500 | £4,250 |
| £1,250,000 | £68,750 | £52,000 | £16,750 |
| £1,500,000 | £93,750 | £64,500 | £29,250 |
| £2,000,000 | £153,750 | £89,500 | £64,250 |

So a £1.5 million site bought as bare land carries £64,500 of SDLT against £93,750 for a £1.5 million house — and against far more once the residential additional-property surcharge is layered on top. None of this is a saving a homebuyer can reach for: it applies because genuine development land is non-residential, full stop. It does explain why the classification of borderline plots is so heavily fought over, and why non-residential rates can undercut the standard residential scale at the very top of the market.
When the charge falls due
On a straightforward land purchase the buyer files a land-transaction return and pays within 14 days of the effective date, usually completion. In the chain above, no return was needed at the grant and assignment stages because the figures sat inside the nil-rate band; the obligation bit only on exercise.
The non-residential scale also has no first-time-buyer relief — that relief is a residential-only measure — so it is never a route that helps an individual buying a home. For any purchase that straddles the residential and non-residential line, the classification turns on the facts of the site at completion, and the numbers move by tens of thousands either way. This is general information, not advice; speak to a qualified adviser before acting.
What the data shows
Land and other non-dwelling property is a small but real slice of the market. In 2025, HM Land Registry recorded 3,605 standard sales coded "Other" — the residual class that captures bare land, commercial units and mixed property — at a median of £376,000 and a mean of £522,890. On the residential side, 28,672 homes (3.7% of 778,998 sales) changed hands above the £925,000 line where the two scales begin to part company, and 8,060 above £1.5 million — a reminder that the divergence bites at the top of the market, not the middle.
