Industrial & Warehouse Stamp Duty
How stamp duty applies to industrial units, warehouses, factories, and distribution centres. Covers non-residential rate bands, plant and machinery severance, lease structures, and multi-unit portfolio purchases.

Key Takeaways
- Industrial units and warehouses pay non-residential SDLT: 0% (up to £150k), 2% (£150k-£250k), 5% (above £250k)
- Non-structural plant and machinery (removable equipment, racking, production lines) can be excluded from SDLT as chattels
- Structural plant (HVAC, electrical, lifts, fire systems) is part of the building and included in the SDLT calculation
- B2 (industrial) and B8 (warehouse) use classes pay identical rates — no SDLT distinction between them
- No additional property surcharge on industrial/warehouse purchases — commercial property is surcharge-exempt
- Multi-unit purchases in a single transaction are aggregated; linked transactions may also be aggregated by HMRC
Non-Residential SDLT Rates
Industrial units, warehouses, factories, and distribution centres are all classified as non-residential property for stamp duty land tax. This applies to B2 (general industrial) and B8 (storage and distribution) use class properties alike. Use our stamp duty calculator to estimate SDLT on your industrial purchase, or read the full commercial property SDLT guide.
| Purchase Price Band | SDLT Rate |
|---|---|
| Up to £150,000 | 0% |
| £150,001 to £250,000 | 2% |
| Above £250,000 | 5% |
B2 and B8: same SDLT, different uses
General industrial (B2) and storage/distribution (B8) properties both pay identical non-residential SDLT rates. The planning use class does not affect the stamp duty calculation. Only the purchase price and tenure (freehold vs leasehold) determine the liability.
Worked Examples
Example 1: £180,000 small industrial unit
0% on first £150,000 = £0
2% on next £30,000 (£150k to £180k) = £600
Total SDLT: £600
Example 2: £1,000,000 warehouse
0% on first £150,000 = £0
2% on next £100,000 (£150k to £250k) = £2,000
5% on remaining £750,000 (£250k to £1m) = £37,500
Total SDLT: £39,500
Effective rate: 3.95%
Example 3: £1,500,000 warehouse with plant & machinery exclusion
Total price: £1,500,000
Less non-structural P&M (racking, conveyor systems): −£200,000
Taxable property element: £1,300,000
0% on £150,000 = £0
2% on £100,000 = £2,000
5% on £1,050,000 = £52,500
Total SDLT: £54,500 (saving £10,000 vs full price)
Exclusion requires proper apportionment in the contract.
Example 4: £5,000,000 distribution centre
0% on first £150,000 = £0
2% on next £100,000 = £2,000
5% on remaining £4,750,000 = £237,500
Total SDLT: £239,500
Effective rate: 4.79%
Plant & Machinery Severance
Industrial and warehouse properties often contain significant plant and machinery — production lines, racking systems, conveyor belts, IT infrastructure. Whether these items are included in the SDLT calculation depends on whether they are legally part of the "land" or are separate personal property (chattels).
The key concept is severance: can the item be removed from the building without permanently damaging either the building or the item itself? Items that can be severed (removed) without damage are more likely to be chattels excluded from SDLT.
Apportionment must be documented
To exclude plant and machinery from SDLT, the purchase contract must separately identify and value the P&M elements. HMRC will challenge apportionments that appear to artificially reduce the stamp duty bill. A professional valuation of the P&M provides a defensible basis.
For large industrial purchases where P&M constitutes a significant proportion of the total price — for example, a food processing facility where production lines and cold storage equipment may represent 30-40% of the transaction value — proper SDLT apportionment can produce substantial savings.
Structural vs Non-Structural Plant
HMRC and the courts distinguish between plant that is integral to the building structure and plant that is operational but not structural. This distinction is crucial for determining what can be excluded from SDLT as a chattel.
Structural (integral) plant — included in SDLT
- • HVAC (heating, ventilation, air conditioning) built into structure
- • Electrical wiring and distribution boards
- • Lifts and escalators
- • Fire suppression and sprinkler systems
- • Gas mains and pipework
- • Concrete-embedded equipment foundations
- • Overhead cranes on fixed gantries
Non-structural plant — potentially excluded
- • Free-standing production machinery
- • Racking and shelving systems
- • Conveyor and picking systems
- • IT equipment and servers
- • Fork-lift trucks and handling equipment
- • Portable compressors
- • Free-standing refrigeration units
Grey areas require professional advice
The boundary between structural and non-structural plant is not always clear. A large automated storage and retrieval system (ASRS) installed on a custom-built mezzanine may be difficult to categorise. Specialist SDLT advice is recommended for transactions involving significant P&M values.
Leasehold Industrial Units
Many industrial and warehouse occupiers hold their premises on a lease rather than owning the freehold. SDLT on industrial leases follows the same NPV-based approach as other commercial leases.
Lease SDLT rates (NPV of rent)
| NPV of Rent | SDLT Rate |
|---|---|
| Up to £150,000 | 0% |
| £150,001 to £5,000,000 | 1% |
| Above £5,000,000 | 2% |
Lease example: 10-year warehouse lease at £80,000/year
NPV (10-year factor at 3.5%: approx 8.317) = £80,000 × 8.317 = £665,360
0% on £150,000 = £0
1% on £515,360 (£665,360 − £150,000) = £5,154
Lease SDLT: £5,154
Industrial leases frequently include rent reviews (typically 5-yearly), service charge obligations, and break clauses. SDLT is calculated on the rent as defined in the lease; variable rent provisions can complicate the calculation and may require reassessment at each review.
Multi-Unit and Portfolio Purchases
Investors and occupiers sometimes buy multiple industrial units or an entire trading estate in a single transaction. The SDLT treatment depends on how the units are purchased.
Aggregation: single transaction
Where multiple units are purchased in a single contract from the same seller, the total consideration is aggregated and SDLT is calculated on the combined price. You cannot split units in a single transaction to benefit from the nil-rate band multiple times.
Linked transactions
HMRC can treat separate transactions as "linked" if they form part of the same arrangement or between the same parties. Linked transactions are aggregated for SDLT, preventing artificial splitting across multiple contracts to reduce the bill.
Genuinely separate transactions with different sellers — for example, buying units from three different vendors on an estate — are not linked and are each taxed independently. The test for linking is whether the transactions are interdependent: would one have proceeded without the other?
Aggregation example
Buying 5 industrial units at £130,000 each = £650,000 total
Single transaction (aggregated):
0% on £150k + 2% on £100k + 5% on £400k = £22,000 SDLT
If genuinely separate (5 × £130k):
Each unit: 0% on £130k = £0 × 5 = £0 SDLT
This illustrates why HMRC scrutinizes artificially split transactions.
Common Questions
How much stamp duty on a warehouse?
Warehouses pay non-residential SDLT: 0% on the first £150,000, 2% on £150,001–£250,000, and 5% above £250,000. On a £1m warehouse, SDLT is £39,500. No additional property surcharge applies.
Can plant and machinery be excluded from stamp duty?
Potentially yes. Plant and machinery not permanently affixed to the building — movable equipment, free-standing machinery, racking — is a chattel and excluded from SDLT. Structural plant (heating systems, electrical wiring, lifts) is part of the building and included.
Is SDLT different for industrial vs warehouse use?
No. Both B2 (general industrial) and B8 (storage and distribution) pay identical non-residential SDLT rates. The use class makes no difference to stamp duty — only the purchase price and tenure matter.
Do I pay stamp duty on an industrial estate with multiple units?
Units purchased in a single transaction are aggregated — you pay SDLT on the total price. Units purchased in genuinely separate transactions from different sellers are taxed independently. HMRC may treat linked transactions as a single purchase.
