Where SDLT actually disappears: UK postcodes below the £125,000 nil-rate (2026)

Most stamp duty coverage asks "how much will you pay?" This piece flips the question. In a quietly large slice of England, the answer is nothing — because the median sale price sits below the £125,000 Stamp Duty Land Tax nil-rate band that came back into effect on 1 April 2025.

How quietly large? Of 804,921 English residential transactions recorded by HM Land Registry in 2025, 76,510 completed below £125,000 — roughly 9.5% of all English sales. After the threshold reverted on 1 April 2025, 53,823 of 529,129 post-April sales were sub-threshold — a 10.2% share measured against the period when the £125,000 band was actually live.

So before any first-time-buyer relief, before any worked SDLT calculation, before any discussion of the 5% slab between £250,001 and £925,000, there is a structural truth worth naming: roughly one in every ten English property sales paid zero standard SDLT in 2025, simply because the price was below £125,000. The threshold is not a rounding artefact. It is the operating regime for a meaningful share of the market.

The English postcode districts where the median sale clears no SDLT

Below are the English postcode districts with at least 200 recorded sales in 2025 whose median sale price sat below the £125,000 nil-rate. At the median, the standard-rate buyer in these districts pays no SDLT before any reliefs are applied.

Source: Homecost transactions table, all completed sales 1 January – 31 December 2025, grouped by postcode district, n ≥ 200. Medians computed across the full district pool, not size-adjusted.

The geographic concentration is striking. The pattern is overwhelmingly Teesside, County Durham, North-East Lancashire, the Humber, Merseyside, Bradford, Stoke and West Cumbria — the same broad belt that has anchored the bottom of the UK affordability map for the last decade.

What the threshold reversion actually changed

Between 23 September 2022 and 31 March 2025, the standard SDLT nil-rate band sat at £250,000 — a temporary uplift introduced by the September 2022 "mini-budget" and confirmed at the November 2022 Autumn Statement. The first-time-buyer nil-rate sat at £425,000 over the same window.

From 1 April 2025, both reverted. The standard nil-rate fell back to £125,000. The first-time-buyer nil-rate fell back to £300,000. The temporary regime was not extended at the Autumn 2024 Budget. (HMRC SDLT residential rates).

For buyers in the districts above, the reversion changed almost nothing in cash terms. A £95,000 sale in FY1 paid no SDLT before 1 April 2025 (price below the £250,000 band) and pays no SDLT after 1 April 2025 (price below the £125,000 band). The disappearance is structural to the price point, not to the regime.

What the reversion did change is the band above the threshold. A £200,000 sale that paid zero SDLT under the £250,000 nil-rate now pays £1,500 under the £125,000 nil-rate (5% of the slice £125,001 → £200,000). That £200,000 boundary is well above the medians shown above, so the districts on the table are insulated — but the next postcode-district step up (in the £140,000–£180,000 range) feels the reversion in full.

What "no SDLT" does not mean

The £125,000 nil-rate covers standard residential SDLT. Three other charges can still apply on the same transaction:

1. The additional-property surcharge. The 5% surcharge for buyers acquiring an additional dwelling (the regime tightened from 3% to 5% at the Autumn 2024 Budget) applies from £40,001 upwards on the full price, not on the slice above £125,000. A £100,000 purchase as a second home or buy-to-let attracts £5,000 of additional-property SDLT — even though the standard-rate buyer at the same price pays nothing. The relevant mechanics are set out in our guide to the additional-property surcharge. Of the 76,510 sub-£125k English sales in 2025, 4,922 completed below the £40,000 surcharge floor — that pool escapes both standard SDLT and the additional-property surcharge. The other 71,588 would attract the 5% surcharge if bought as an additional dwelling.
2. The non-resident surcharge. A 2% surcharge for non-UK-resident buyers stacks on top of standard rates and the additional-property surcharge. On a £100,000 main-residence purchase by a non-resident buyer, that is £2,000 — payable even though the standard-rate slab is zero.
3. Higher rates for companies and certain trusts. A 17% flat rate applies to corporate purchasers of single dwellings above £500,000 (the 15% rate also applies in some legacy cases), and bare trust / nominee arrangements have their own treatment — see our bare-trusts and nominees explainer.

For an owner-occupier main residence at the median price in any of the districts above, none of those three stacks engages. The result is a clean zero.

How the SDLT pillar reframes once you accept this

The standard framing of the SDLT debate runs through the £250,000 slab, the £500,000 first-time-buyer cliff and the upper-band slabs. That framing is correct for the median English purchase, which sat at roughly £290,000 in 2025 (HM Land Registry, full-year mean). It is wrong-headed for the 9.5% of the market that operates below the nil-rate.

For that sub-pool, the policy levers that matter are not slab geometry — they are the additional-property surcharge floor (£40,000), the non-resident surcharge (a flat 2%), and the FTB relief threshold (which is irrelevant for these buyers, since the standard nil-rate already gives them zero). The SDLT bunching at the £125,000 threshold piece showed how thin the cliff-edge bunching is at this band in 2025 — because so few buyers across the country sit on either side of it. The districts above are the ones that do sit either side of it. They are where the threshold actually does work.

A worked SDLT-zero scenario

A standard-rate buyer purchasing a 2-bed terrace in DL14 (Bishop Auckland) at the 2025 district median of £97,000:

• Standard SDLT: £0 (price below £125,000 nil-rate).
• First-time-buyer relief: not needed (standard nil-rate already covers the full price).
• Additional-property surcharge: not applicable (main residence).
• Non-resident surcharge: not applicable (UK-resident buyer).
• Total SDLT payable: £0.

The same buyer using a 5-year fixed mortgage at the Bank of England's quoted 75% LTV 5-year rate of 4.32% (April 2026 release) would pay roughly £392/month on a £72,750 loan over 25 years (75% LTV, 25% deposit of £24,250). Add Darlington's 2026-27 Band D council tax of £2,493.83/year, and a representative running cost stack is approximately £600/month before utilities — broadly below the lower decile of UK private rent.

Wales: a separate regime, an even broader zero band

For completeness: Wales does not use SDLT. The Welsh Land Transaction Tax (LTT) has a £225,000 main-residence nil-rate. By that yardstick, the comparable "zero LTT" pool is much broader — of 43,328 Welsh transactions in 2025, 6,974 (16.1%) completed below £125,000 alone, and far more sit between £125,001 and the £225,000 LTT threshold. The SDLT vs LBTT vs LTT comparison piece works through the cross-regime detail.

Methodology notes

• All sales counts derived from HM Land Registry Price Paid Data, ingested into the Homecost transactions table. Postcode → country attribution via OS Code-Point Open via Homecost's postcodes table.
• Median is the standard 50th percentile across each district's 2025 transaction pool. Districts with fewer than 200 sales in 2025 are excluded to avoid noise from very thin markets.
• Medians are unadjusted for property type, size or new-build mix. A district with a high proportion of small terraces will rank lower than its detached-stock neighbour even at identical £/sqm.
• The £125,000 standard nil-rate applies to England and Northern Ireland from 1 April 2025. Scotland (LBTT) and Wales (LTT) have their own thresholds.

Across 30,980,257 Land Registry transactions in the Homecost database back to 1995 and the 296 English billing authorities tracked in 2026-27, the sub-£125k pool is small in headline value terms but representative of a real chunk of English buyers.
