Surrender and Regrant: Lease Restructuring SDLT
How SDLT applies when an old lease is surrendered and a new one granted — deemed surrenders, overlap relief, reverse premiums, and worked examples.
Key Takeaways
- Surrender and regrant occurs when an old lease is surrendered and a new lease is simultaneously granted — SDLT treats the new lease as a brand new grant
- The surrendered lease itself does not attract SDLT — only the new (regranted) lease is a taxable event
- Overlap relief is available to credit NPV already taxed under the surrendered lease against the new lease SDLT
- A deemed surrender and regrant can arise without any formal surrender document — if lease terms are varied so fundamentally that law treats it as a new lease
- Key triggers for deemed surrender: extending the lease term, adding new premises, or fundamentally restructuring the rent
- Reverse premiums (landlord paying the tenant) are not SDLT-chargeable to the tenant but may have other tax consequences
- Commercial surrender and regranted leases use non-residential NPV rates (0%/1%/2%) and premium rates (0%/2%/5%)
- The 14-day filing deadline runs from the effective date of the new regranted lease, not the date of surrender

What is Surrender and Regrant?
Surrender and regrant (often abbreviated to "S&R") is a lease restructuring mechanism in which:
- The existing lease is surrendered — the tenant hands the lease back to the landlord, extinguishing it.
- The landlord simultaneously grants a new lease — on different terms (different rent, different term, different premises, or some combination).
The net result is that the old lease disappears and a new lease takes its place. From HMRC's perspective, the new lease is a fresh grant and therefore a new taxable event for SDLT purposes.
Surrender and regrant is most commonly used in commercial contexts: extending a lease term beyond what a simple variation could achieve, adding new premises to an existing tenant's occupation, restructuring rent to reflect market conditions, or as part of a development or refinancing exercise.

SDLT on the New (Regranted) Lease
The SDLT liability on a surrender and regrant falls entirely on the new lease. The surrender itself is not a taxable event — no SDLT arises merely from handing back the old lease. Only the grant of the new lease triggers SDLT.
The new lease is taxed in exactly the same way as any other new lease grant:
- Premium: any upfront payment on the new lease is taxed at standard non-residential (or residential, as applicable) SDLT rates
- NPV of rent: all future rent under the new lease is discounted at 3.5% to produce an NPV figure, which is then taxed at the appropriate NPV rate bands
- Overlap relief: NPV credit for any period already taxed under the surrendered lease is deducted before applying NPV rates
For commercial surrenders and regranted leases, apply the commercial NPV rate bands (0% up to £150,000, 1% on £150,001 to £5 million, 2% above). For residential, apply the residential NPV bands (0% up to £125,000, 1% above). See our commercial lease SDLT guide for the full NPV calculation methodology.
Overlap Relief on Surrender and Regrant
Overlap relief is the SDLT mechanism that prevents the same period of time from being taxed twice. Where a new lease (the regrant) starts from the same point as the surrendered lease — or from an earlier point if the term is backdated — the NPV of those already-taxed years is credited against the new lease NPV.
Overlap Relief Mechanics for S&R
The overlap period is the unexpired term remaining on the surrendered lease at the time of surrender. The NPV of that period (calculated at the old rent, discounted at 3.5% from year 1) is the overlap credit.
SDLT rates then apply only to this taxable NPV figure.
If the surrendered lease had a significant unexpired term at a substantial rent, the overlap credit can substantially reduce or even eliminate SDLT on the new lease. Conversely, if the surrendered lease had very little time remaining, the overlap credit is minimal and the new lease's full term is effectively taxed from year 1.
Deemed Surrenders: When Lease Variations Trigger New SDLT
A deemed surrender and regrant is one of the most important and frequently misunderstood concepts in lease SDLT. It arises where a variation to a lease is so fundamental in nature that the law treats the old lease as having been surrendered and a new lease granted — even though the parties may only have intended a straightforward amendment.
What Triggers a Deemed Surrender?
| Type of Variation | Deemed S&R? |
|---|---|
| Extending the lease term | Yes — deemed S&R |
| Adding new premises to the demised area | Yes — deemed S&R |
| Changing the parties (new landlord/tenant by variation) | Possibly — depends on facts |
| Reducing the premises | No |
| Changing rent within existing structure | Generally no |
| Changing permitted use or other covenants | No |
The case law principle is that a variation that grants the tenant something that cannot exist under the original lease — such as occupation of different or additional premises, or a term that extends beyond the existing expiry — constitutes a deemed surrender and regrant of the whole lease.
Variation vs New Lease: Practical Distinctions
In practice, distinguishing between a permissible variation and a deemed surrender and regrant requires careful legal advice. The stakes are significant:
Simple Variation (no new SDLT)
- • Changing the permitted use clause
- • Amending service charge provisions
- • Altering alterations consent requirements
- • Modifying rent review timing
- • Adding a break clause
Deemed S&R (new SDLT arises)
- • Adding a floor to the demised premises
- • Extending the contractual expiry date
- • Granting access to additional land
- • Including previously excluded areas
- • Any change requiring a new lease to take effect
If you are unsure whether a proposed variation constitutes a deemed surrender, always seek specialist property tax advice before executing the variation document.
Commercial vs Residential Surrender and Regrant
While surrender and regrant is predominantly encountered in commercial settings, it can arise on residential leases — most commonly in development or estate management contexts.
| Aspect | Commercial | Residential |
|---|---|---|
| NPV nil-rate threshold | £150,000 | £125,000 |
| NPV tax rate above threshold | 1% (up to £5m), 2% above | 1% (flat rate above £125k) |
| Premium tax rates | 0% / 2% / 5% | 0% / 2% / 5% / 10% / 12% |
| Higher rates surcharge | Does not apply | May apply (additional dwellings) |
| Deemed S&R triggers | Same as residential | Same as commercial |
Worked Example: Commercial Surrender and Regrant
Scenario
A retail tenant currently holds a 10-year lease with 4 years remaining at £40,000/year. The tenant and landlord agree to surrender the old lease and grant a new 10-year lease at £55,000/year, covering the existing premises plus an additional storage unit (making this a deemed surrender and regrant).
- • Old lease: 4 years remaining at £40,000/year
- • New lease: 10 years at £55,000/year
- • Premium: £25,000 (for access to additional storage)
Step 1: SDLT on Premium (£25,000)
£25,000 is below the £150,000 nil-rate threshold for non-residential property.
Step 2: Overlap Credit
NPV of remaining 4 years on old lease at £40,000/year:
Step 3: NPV of New Lease
NPV of £55,000/year for 10 years at 3.5%:
Step 4: Taxable NPV After Overlap Relief
Step 5: SDLT on Taxable NPV
| Band | Rate | SDLT |
|---|---|---|
| £0 - £150,000 @ 0% | 0% | £0 |
| £150,001 - £310,515 @ 1% | 1% | £1,605 |
| SDLT on NPV | £1,605 | |
| SDLT on premium (£25,000) | £0 |
| SDLT on taxable NPV (£310,515) | £1,605 |
| Total SDLT | £1,605 |
Practical Considerations
Several practical points arise in surrender and regrant transactions that can affect the SDLT calculation:
Simultaneous completion
Surrender and regrant must be simultaneous — the old lease must end and the new lease must begin at the same moment. If there is a gap, the tenant may lose occupation rights and SDLT treatment can differ. Your solicitor will ensure the documents are structured correctly.
Sub-tenants and mortgagees
If the surrendering tenant has sub-tenants or the lease is mortgaged, the surrender will overreach the sub-lease and potentially affect the mortgage. Sub-tenants may have independent LTA 1954 rights. These complications can delay or affect the S&R and must be resolved before proceeding.
Stamp Duty Land Tax registration
The regranted lease must be registered at HM Land Registry if the term is over 7 years or the property is already registered. SDLT must be paid before registration. The solicitor submits the SDLT return and uses the HMRC certificate to complete registration.
Frequently Asked Questions
Does the tenant pay SDLT on the surrender?
No. The surrender itself (handing back the old lease) does not attract SDLT. Only the grant of the new lease is a chargeable transaction. If the tenant receives a reverse premium from the landlord as part of the surrender, that does not create SDLT either.
What if the new lease is at a lower rent than the old one?
SDLT is still calculated on the new lease's rent NPV, with overlap relief for the surrendered period. If the new rent is lower, the NPV will be lower. Combined with the overlap credit, there may be little or no SDLT. However, HMRC may review whether the restructuring has a tax avoidance purpose if the economic substance of the lease has been fundamentally altered.
Can a residential leaseholder use surrender and regrant?
Yes, but it is rarely used in residential contexts because residential lease extensions are typically handled under the Leasehold Reform Act 1993 (statutory route) or through voluntary extension. S&R may arise in residential development when a developer takes back a short lease and regrants a longer one as part of a regeneration scheme.
How does surrender and regrant differ from a lease extension?
A lease extension (dealt with under the Leasehold Reform Act or by informal deed of variation that does not involve surrender) continues the existing lease on extended terms. A surrender and regrant ends the old lease entirely and creates a completely new one. The legal distinction matters for security of tenure, sub-lease treatment, and SDLT overlap relief calculations. See our lease extension stamp duty guide for comparison.
Is stamp duty avoidance possible through surrender and regrant structuring?
HMRC is alert to arrangements that use surrender and regrant artificially to reduce SDLT. The general anti-abuse rule (GAAR) and targeted SDLT anti-avoidance provisions can apply. Genuine commercial restructurings that happen to reduce SDLT are not automatically problematic, but arrangements where the primary driver is tax reduction risk challenge.
