Multiple Dwellings Relief (MDR) Complete Guide
Understanding the relief that was abolished in June 2024.
Key Takeaways
- MDR was abolished on 1 June 2024. Contracts exchanged on or after 6 March 2024 cannot claim the relief regardless of completion date
- Transitional protection only applies if you exchanged before 6 March 2024 AND completed before 1 March 2025. Just one day past deadline means no relief
- Government expects abolition to raise £50m annually by 2028-29, primarily impacting buy-to-let investors and property developers
- The 1% minimum rule meant MDR savings were often smaller than expected. Total SDLT could never fall below 1% of purchase price
- Six or more dwellings can still use non-residential rates (0%, 2%, 5%) instead of residential rates. This separate relief survived MDR abolition
- MDR abolition increased SDLT dramatically for portfolio purchases. Buying 3 flats for £600k now costs £20,000 instead of £6,000 under MDR
- HMRC frequently challenged MDR claims on properties with small annexes or granny flats. Many tribunal cases defined what counted as a "dwelling"
- No replacement relief was introduced. Purchasing 2-5 dwellings now attracts full residential SDLT with 5% surcharge on investment properties
MDR Abolished on 1 June 2024
Multiple Dwellings Relief is no longer available for transactions completing on or after 1 June 2024. This page explains the historical relief and transitional provisions for contracts exchanged before 6 March 2024.

What Was Multiple Dwellings Relief?
Multiple Dwellings Relief (MDR) was a stamp duty relief that applied when you purchased two or more dwellings in a single transaction. Instead of calculating SDLT on the total purchase price, MDR allowed you to calculate it based on the average price per dwelling. Use our stamp duty calculator to estimate current tax.
The relief was designed to prevent unfair tax outcomes where buying multiple small properties in one transaction would attract higher SDLT rates than buying them separately.
Who Benefited from MDR?
- •Buy-to-let investors: Purchasing property portfolios
- •Property developers: Buying blocks of flats
- •Homeowners: Buying properties with annexes, granny flats, or separate cottages
- •Student accommodation buyers: HMOs and purpose-built student blocks
How MDR Worked
MDR changed the SDLT calculation by dividing the total purchase price by the number of dwellings to calculate an average price, then applying SDLT rates to that average, and multiplying the result by the number of dwellings.
MDR Calculation Example
Without MDR (standard calculation):
- SDLT on £800,000 as one transaction
- Higher rate bands apply to full amount
- Total SDLT: £50,000 (with 5% surcharge)
With MDR (historical):
- Average price: £800,000 ÷ 4 = £200,000
- SDLT on £200,000 = £15,000 (with surcharge)
- Total: £15,000 × 4 = £60,000
- Actually higher in this case due to 1% minimum rule
The 1% Minimum Rule
MDR had a safety net: the total SDLT payable could never be less than 1% of the total purchase price. This prevented extremely low SDLT bills when buying many very cheap properties.
MDR Abolition: What Happened
In the Spring Budget 2024 (6 March 2024), Chancellor Jeremy Hunt announced the abolition of MDR, effective for transactions completing on or after 1 June 2024. The Finance Act 2024 formally ended the relief that had existed since 2011.
Government Rationale
- •Revenue generation: Expected to raise £50m per year by 2028-29
- •Simplification: Reducing the complexity of SDLT calculations
- •Fairness: Relief mainly benefited investors and landlords, not first-time buyers
- •Abuse prevention: Some claims were contentious (e.g., properties with small annexes)
The abolition significantly increased SDLT bills for investors purchasing property portfolios and for homeowners buying properties with separate dwellings on the same title.
Who Can Still Claim MDR?
MDR is only available for transactions where:
Transitional Provisions Apply
- ✓Contracts were exchanged BEFORE 6 March 2024, AND
- ✓Completion occurred BEFORE 1 March 2025
If you exchanged contracts on or after 6 March 2024, you cannot claim MDR regardless of when you complete. All contracts exchanged from 6 March 2024 onwards are excluded from the relief.
What Were the MDR Rules?
MDR calculated stamp duty by dividing the total purchase price by the number of dwellings, applying SDLT rates to the average price per dwelling, then multiplying the result by the number of dwellings.
MDR Formula
Historical Example (No Longer Available)
Purchase 3 flats for £600,000 total (before 1 June 2024):
Without MDR (post-abolition): £20,000
Transitional Provisions
The government provided transitional relief for transactions that were already in progress when MDR was announced to be abolished.
Critical Dates
| Date | Event | Impact |
|---|---|---|
| 6 March 2024 | Budget announcement | MDR abolition revealed |
| Before 6 March | Contract exchanged | MDR still available |
| On/after 6 March | Contract exchanged | MDR not available |
| 1 June 2024 | Completion date cutoff | All completions after: no MDR |
Who Qualified for Transitional Relief?
You could still claim MDR if:
- You exchanged contracts before 6 March 2024, AND
- You completed the transaction on or after 1 June 2024
This protected buyers who had committed to purchases before the abolition was announced but faced delays in completion.
Alternatives After MDR Abolition
While MDR has been abolished, there is still one relief available for purchasing multiple residential properties:
Six or More Dwellings Rule
If you purchase six or more dwellings in a single transaction, you can elect to pay SDLT at non-residential rates instead of residential rates. This is not MDR, but a separate relief that was retained after MDR abolition.
Non-residential rates (still available):
- Up to £150,000: 0%
- £150,001-£250,000: 2%
- Above £250,000: 5%
These rates are often lower than residential rates, especially when the 5% additional property surcharge applies.
Planning Post-MDR
- •Separate transactions: Buying properties in separate transactions (if commercially viable)
- •Commercial rates: Ensure 6+ dwellings qualify for non-residential SDLT
- •Corporate structures: Consider limited company purchase (but beware 17% corporate rate for residential over £500k)
Historical Context and Why It Was Abolished
MDR was introduced in 2011 to encourage housing development and prevent unfair tax outcomes where buying multiple small properties in one transaction would attract disproportionately high SDLT. However, it became increasingly controversial.
HMRC Challenges
HMRC frequently challenged MDR claims. See our guide to MDR HMRC challenges for more detail, particularly for:
- Properties with small annexes: Was a 200 sq ft granny flat really a separate dwelling? Many homeowners claimed MDR on properties with tiny annexes or converted garages.
- Houses with planning permission: Could potential dwellings (not yet built) count for MDR? Tribunals ruled planning permission alone was insufficient.
- Self-contained vs. non-self-contained: When did an extension with a kitchenette become a "dwelling"? The definition was heavily litigated.
- Investor portfolios: Large-scale claims on property portfolios saved substantial amounts but were seen as aggressive tax planning.
Case Law Developed Around MDR
Numerous tribunal cases defined what counted as a "dwelling" for MDR purposes. See our MDR case law analysis:
- • Fiander v HMRC (2017): Cottage in grounds of main house qualified as separate dwelling for MDR
- • Sandhu v HMRC (2018): Planning permission alone not enough, dwelling must be habitable at purchase
- • Hurstwood Properties v HMRC (2019): Self-contained flats within a house could qualify if genuinely separate
- • Gateley LLP v HMRC (2014): Each unit must be capable of independent occupation
Why the Government Abolished It
By 2024, MDR had become seen as a loophole rather than a legitimate relief:
- Primarily benefited investors: The vast majority of claims were from buy-to-let landlords and property developers, not ordinary homebuyers. See our landlord guide for current rules.
- Revenue cost: The relief reduced SDLT revenue by tens of millions annually
- Complexity and disputes: HMRC spent significant resources challenging questionable claims
- Gaming the system: Some buyers artificially created separate dwellings (adding basic kitchens to annexes) solely to claim MDR
The abolition was relatively uncontroversial politically, as the relief was widely seen as benefiting wealthy investors rather than helping people onto the property ladder.
Frequently Asked Questions About Multiple Dwellings Relief
Can I still claim Multiple Dwellings Relief?
No, Multiple Dwellings Relief was abolished on 1 June 2024 and is no longer available. The only exception is for transactions where contracts were exchanged before 6 March 2024 AND completed before 1 March 2025 (transitional provisions). If you exchanged contracts on or after 6 March 2024, you cannot claim MDR regardless of when you complete. For transactions involving 6 or more dwellings, you may be able to use non-residential SDLT rates instead, which can still offer savings compared to residential rates with the 5% surcharge.
When was MDR abolished?
MDR was abolished on 1 June 2024, as announced in the Spring Budget on 6 March 2024. The Finance Act 2024 formally removed the relief from the stamp duty legislation. Any transaction completing on or after 1 June 2024 cannot claim MDR, unless it qualifies under the transitional provisions (contract exchanged before 6 March 2024). The relief had existed since 2011 but became increasingly controversial due to perceived abuse by investors using it to reduce SDLT on properties with small annexes or multiple units.
What replaced Multiple Dwellings Relief?
Nothing directly replaced MDR. However, purchases of 6 or more dwellings in a single transaction can still elect to be treated as non-residential for SDLT purposes, which may offer savings. Non-residential rates are 0% up to £150,000, 2% from £150,001 to £250,000, and 5% above £250,000. This is often cheaper than paying residential rates plus the 5% additional property surcharge, especially for portfolio purchases. The government chose not to replace MDR with an alternative relief, viewing it as primarily benefiting investors rather than serving a legitimate policy purpose.
Can I buy 6 properties at non-residential rates?
Yes, if you purchase 6 or more residential dwellings in a single transaction, you can elect to pay SDLT at non-residential rates rather than residential rates. This rule survived the abolition of MDR. The non-residential rates (0%, 2%, 5%) are often lower than residential rates, particularly when the 5% additional property surcharge applies. However, you must genuinely purchase 6+ dwellings in one transaction. You cannot artificially split or combine purchases to manipulate the count. The dwellings must be suitable for use as separate dwellings at the time of purchase. Consult a tax advisor to ensure your transaction qualifies.
How did MDR work before abolition?
Before abolition, MDR worked by dividing the total purchase price by the number of dwellings to calculate an average price per dwelling. SDLT was then calculated on this average price using standard rates, and the result was multiplied by the number of dwellings. A 1% minimum rule applied. The total SDLT could never be less than 1% of the total purchase price. For example, buying 4 flats for £800,000 meant an average of £200,000 per flat. SDLT on £200,000 was £1,500, multiplied by 4 = £6,000 (but 1% minimum = £8,000, so you paid £8,000). Without MDR post-abolition, the same purchase costs £50,000 in SDLT with the 5% surcharge.
Post-Abolition Alternatives
While MDR has been abolished, there is still one relief available for purchasing multiple residential properties:
Six or More Dwellings Rule
If you purchase six or more dwellings in a single transaction, you can elect to pay SDLT at non-residential rates instead of residential rates. This is not MDR, but a separate relief that was retained.
Non-residential rates (still available):
- Up to £150,000: 0%
- £150,001-£250,000: 2%
- Above £250,000: 5%
These rates are often lower than residential rates, especially when the 5% additional property surcharge applies.
Planning Post-MDR
- •Separate transactions: Buying properties in separate transactions (if commercially viable)
- •Commercial rates: Ensure 6+ dwellings qualify for non-residential SDLT
- •Corporate structures: Consider limited company purchase (but beware 17% corporate rate)
- •Timing: For portfolios, complete all contracts before 1 June 2024 if exchanged before 6 March 2024
