Commercial Property for Non-UK Residents: No SDLT Surcharge

"I live overseas. How much extra will it cost me to buy in the UK?" It's one of the first questions international investors and British expats ask me, usually right after their solicitor has quoted stamp duty land tax (SDLT) on a UK Buy To Let. For commercial property, the answer is very different.

A quick note before the numbers: this article explains how the stamp duty rules work in general, not how they apply to you. It isn't tax advice, so please speak to a qualified tax adviser before committing to a purchase.

How much stamp duty do non-UK residents pay on Buy To Let?

For residential property in England and Northern Ireland, the honest answer is: a lot. A non-UK resident buying a Buy To Let pays the standard SDLT rates, plus typically the 5% higher rate for additional dwellings, plus the 2% non-resident surcharge. That's an extra 7% on every band of the price, before a single month's rent comes in.

Many overseas investors assume the 5% higher rate only applies if they already own UK property. It doesn't. HMRC counts residential property you own anywhere in the world, so if you own your home in the country where you live, a UK Buy To Let will usually be treated as an additional dwelling and the 5% applies on top of the 2%.

No SDLT surcharge on commercial or semi-commercial property

Commercial property works differently. Non-residential SDLT carries no additional dwelling surcharge and no non-resident surcharge. An investor based in Dubai, Hong Kong or Nairobi pays exactly the same stamp duty on a warehouse as a buyer in Manchester. For once, international investors start on a level playing field.

The same applies to mixed-use or semi-commercial property, such as a shop with a flat above. Because it isn't wholly residential, it's taxed at the non-residential rates, with neither surcharge. And it applies whether you're a foreign national or a British expat: for SDLT, what counts is where you live, not which passport you hold.

Stamp duty compared on a £500,000 purchase

The numbers on a £500,000 purchase make the point:

• Non-UK resident buying a Buy To Let: £50,000 SDLT
• UK-resident landlord buying the same Buy To Let: £40,000 SDLT
• Anyone, UK or overseas, buying a £500,000 commercial unit: £14,500 SDLT

That's £35,500 more of an overseas investor's capital working in the asset rather than paid in tax on day one.

Best UK commercial property sectors and regions for yield and growth

So where are the best returns? Looking at the latest industry forecasts and market data, three sectors stand out for combining solid income with growth:

1. Industrial and warehousing, particularly multi-let estates of smaller units. It has the strongest forecast rental growth (3.0% a year) and capital growth (2.5% a year) of any sector to 2030, according to the Real Estate:UK consensus forecasts. Allsop reports that multi-let estates returned 9.9% in 2025.
2. Retail warehousing (out-of-town retail parks). Forecast total returns of around 8.0% a year to 2030, with good secondary parks yielding around 6.5%.
3. Best-in-class regional offices. Rents for the best city-centre space are rising sharply, with Lambert Smith Hampton forecasting 13% average growth across the Big Six regional cities this year. Secondary offices are a different story and need real caution.

On location, the regions outside London and the South East offer higher yields with growth that is keeping pace:

1. The North West, led by Manchester, where prime office rents are forecast to rise 22% this year.
2. Yorkshire and the Humber, led by Leeds. Allsop expects these first two regions to lead UK industrial rental growth in 2026.
3. The Midlands, where RICS surveyors report the strongest industrial rental expectations alongside the North, and the East Midlands took 38% of UK big-warehouse lettings in the first half of 2026.

Forecasts are not guarantees, and returns within any sector vary widely from one property to the next. Location, tenant strength and lease length matter as much as the headline sector.

Commercial mortgages for non-UK residents and expats

None of this makes commercial property a tax-free route. Non-residents still pay UK tax on rental profits and on gains, and Scotland and Wales have their own land taxes. Lending is also more selective: fewer lenders on our 250+ strong panel will fund overseas borrowers, though a number of specialist lenders do consider British expats and foreign nationals for both commercial and semi-commercial mortgages. Those lenders look closely at income, residency and ownership structure, whether that's personal names, a UK SPV or an overseas company. Our guide for expat and international borrowers explains what lenders look for, and our commercial investment mortgages page covers how terms are set.
