Rollover relief for property under section 152 of the Taxation of Chargeable Gains Act 1992 is one of the most misunderstood areas of UK property tax. The headline framing ('reinvest disposal proceeds into a replacement property to defer CGT') is right for the narrow population of qualifying trades; it is wrong for the standard buy-to-let landlord who makes up most of the audience that searches for this relief.

This guide sets out the s.152 framework, the section 155 Class 1 Head A qualifying-asset gateway, the trade-versus-investment case-law spine that closes the relief to standard BTL landlords, the narrow groups that do qualify, and the alternative reliefs available for landlords who don't. The two worked examples (a qualifying commercial owner-occupier disposal and a failed BTL disposal) show the boundary in practice.

What rollover relief is (and isn't) for property landlords

Rollover relief under section 152 TCGA 1992 lets a trader defer CGT by reinvesting disposal proceeds into a qualifying replacement business asset. The deferral works by rolling the gain into the base cost of the replacement asset, postponing the tax point until the replacement asset is eventually disposed of.

The relief is structured around three load-bearing tests:

  • Trade test: both the disposed asset and the replacement asset must be qualifying business assets used in a trade. Investment activity does not qualify.
  • Qualifying-asset test: the assets must fall within the eight classes set out in section 155 TCGA 1992. Class 1 Head A is the relevant class for property: 'any building or part of a building, and any permanent or semi-permanent structure in the nature of a building, occupied (as well as used) only for the purposes of the trade'.
  • Reinvestment window test: the replacement asset must be acquired in the window of 12 months before to 36 months after the disposal (s.152(3)).

The Class 1 Head A 'occupied (as well as used) only for the purposes of the trade' wording is the load-bearing exclusion of investment property. The asset must be physically occupied by the trader for the trade purposes, not let to a third party. This is the structural reason standard BTL is closed to s.152 rollover.

Trade versus investment: why standard BTL is closed

Standard residential letting is settled as investment activity, not a trade, under a long line of authority. The starting point is Salisbury House Estates Ltd v Fry [1930] AC 432 (House of Lords), which established that letting property is investment activity for business-rules taxation purposes. The reasoning runs that the rental income is a return on the capital invested in the property, and the property itself is not 'occupied' by the trader (it is occupied by the tenant).

Griffiths v Jackson [1983] STC 184 confirmed that even substantial management activity (multiple lettings, hands-on tenancy management, active intervention) does not turn investment into trade where the underlying activity is letting. The volume of management work is not the test; the nature of the activity is.

The badges-of-trade framework in Marson v Morton [1986] STC 463 supplies the analytical structure for distinguishing trade from investment generally. The nine factors:

  1. Profit-seeking motive
  2. Number of transactions
  3. Nature of the asset
  4. Similarity to other trades
  5. Supplementary work performed on the asset
  6. The way the sale was carried out
  7. Source of finance
  8. Time between purchase and sale
  9. Method of acquisition

The factors are not weighted formally; the overall picture determines the classification. For standard BTL, the picture is settled: long-held passive ownership, income from tenants, no supplementary work, no quick-turn sales, investment-style financing. Investment, not trade. Iswera v IRC [1965] 1 WLR 663 supplies the subjective-purpose test sometimes cited on the motive question.

The Section 24 mortgage interest restriction introduced from April 2017 onwards reinforces HMRC's position. If BTL were considered a trade, landlords would receive full business expense relief on finance costs rather than the restricted 20% basic-rate credit. The legislative treatment of finance costs is evidence of HMRC's view that letting is investment.

When property does qualify for rollover relief

Three groups of property holdings qualify for s.152 rollover in 2026/27:

Commercial owner-occupier traders

The textbook qualifying case is a sole trader or partnership that owns the freehold of the property used for the trade. Examples: a chartered surveyor selling her freehold office to buy a larger freehold office for the practice; a manufacturer selling a workshop to buy a larger workshop; a vet selling a clinic to buy new premises. The disposed asset is occupied AND used only for the trade; the replacement asset will be occupied AND used only for the trade. The s.155 Class 1 Head A test is met on the facts.

HMRC working position is in CG60280: the farmer-buying-excess-land example shows the boundary on the 'reasonable purpose' test. The replacement asset must be acquired for the trade use, not primarily for resale gain.

Property developers with evidenced trading status

A property developer who acquires land or buildings with the intention to develop, sells the completed development, and reinvests in further development land can claim rollover under s.152. The qualifying threshold is genuine trading status under the badges-of-trade test: frequent transactions, profit-seeking motive, active development work, business-finance structures, short to medium holding periods. HMRC scrutinises property-developer rollover claims carefully because the boundary with investment is fact-specific. Single-project developers and casual flippers are less likely to satisfy the trading threshold than active multi-project developers with established business records. Working position: BIM60020 and BIM60030.

Pre-6-April-2025 Furnished Holiday Lettings (historic)

The Furnished Holiday Lettings regime treated FHL as 'quasi-trading' for limited CGT purposes including s.152 rollover. FHL was abolished by Finance Act 2025 Schedule 5 with effect from 6 April 2025. Pre-abolition disposals could claim rollover where the FHL business met the qualifying conditions (the let was substantially commercial, the property was available for 210 days a year and actually let for 105 days, etc.).

Anti-forestalling rules between the 6 March 2024 announcement and the 5 April 2025 abolition closed routes that attempted to crystallise pre-abolition disposals artificially. Post-6-April-2025 former FHL property is treated as standard residential rental and does not qualify for rollover. The grandfathered position on remaining FHL features (BADR transitional, capital allowances grandfathering) is in the Wave 6 FHL grandfathered claims guide.

Reinvestment window and partial relief (s.152(3) + s.153)

Section 152(3) sets the reinvestment window at 12 months before to 36 months after the disposal date. The replacement asset must be acquired within this 48-month total window. HMRC can extend the period in exceptional circumstances on application (illness, delayed planning permission, force majeure events), but extension is rare and requires strong evidenced grounds.

Where the full proceeds are reinvested in qualifying replacement assets at least equal in cost to the disposal proceeds, full relief applies: the entire chargeable gain rolls into the base cost of the replacement asset and the original disposal is fully deferred.

Where only part of the proceeds is reinvested, section 153 TCGA 1992 provides partial relief. The chargeable gain is reduced by the rollover amount, with the unreinvested portion taxed as a chargeable gain in the year of disposal. The mechanic operates on a 'lesser of' basis: the relief is limited to the amount actually reinvested. If the replacement asset costs less than the chargeable gain itself, the rolled-over portion is limited correspondingly.

Worked example 1: Anjali commercial-premises rollover (success)

Anjali is a sole-trader chartered surveyor in Bristol. She has run her practice from a freehold office that she bought in 2015 for £200,000. The office has always been used exclusively for the surveying practice (no residential use, no letting to third parties). In June 2026 she sells the office for £400,000 and reinvests £450,000 in a larger freehold office for the same practice.

Step 1: chargeable gain on disposal

  • Sale proceeds (net of incidental costs): £395,000
  • Base cost (purchase price + acquisition costs): £205,000
  • Chargeable gain: £190,000

Step 2: rollover qualification check

  • Disposed asset: freehold office occupied AND used only for the trade. Qualifies under s.155 Class 1 Head A.
  • Replacement asset: freehold office occupied AND used only for the trade. Qualifies under s.155 Class 1 Head A.
  • Reinvestment window: replacement acquired within 36 months after disposal. Qualifies under s.152(3).
  • Full reinvestment: £450,000 replacement cost exceeds £395,000 disposal proceeds. Full relief.

Step 3: rollover effect

  • Chargeable gain on 2026 disposal: £0 (fully deferred)
  • Base cost of replacement office: £450,000 − £190,000 rolled-over gain = £260,000
  • The £190,000 deferred gain crystallises when Anjali eventually disposes of the new office

Anjali pays no CGT on the 2026 disposal. The deferred gain will be added back to the chargeable gain on the next disposal of the trade premises. If she rolls again into a further qualifying asset, the deferral can be extended indefinitely. If she retires and disposes without reinvesting, the deferred gain crystallises in full in that year.

Worked example 2: Marcus failed-qualification BTL (standard CGT)

Marcus owns 8 residential BTL properties in Manchester, all let on standard ASTs. He sells one in June 2026 for £280,000 (acquired in 2014 for £120,000) and reinvests £290,000 in another residential BTL in Salford for the rental portfolio.

Step 1: chargeable gain on disposal

  • Sale proceeds (net of incidental costs): £275,000
  • Base cost (purchase price + acquisition costs + capital improvements): £125,000
  • Chargeable gain: £150,000

Step 2: rollover qualification check

  • Disposed asset: residential property let to tenants. NOT 'occupied (as well as used) only for the purposes of the trade' under s.155 Class 1 Head A. Tenants occupied the property; Marcus did not.
  • Underlying activity: residential letting. Settled as investment under Salisbury House Estates v Fry [1930].
  • Result: rollover not available. The £150,000 chargeable gain is fully taxable in 2026/27.

Step 3: standard CGT computation (no rollover)

  • Chargeable gain: £150,000
  • Less £3,000 annual exempt amount: £147,000 taxable gain
  • Marcus has employment income of £75,000 in 2026/27 (higher-rate throughout). Full gain at 24%: £35,280 CGT
  • 60-day CGT return due 60 days after completion (the gain triggers UK-resident filing)

The reinvestment in another BTL has no CGT effect: it's just a use of after-tax cash to acquire another investment asset. The £290,000 replacement cost becomes the base cost of the new property for the eventual disposal. No deferral.

This is the typical landlord scenario. Most readers searching for 'rollover relief property' are in Marcus's position, not Anjali's. The honest answer is the standard CGT computation plus the alternative-reliefs survey below.

Property companies and rollover relief

Incorporation does not change the underlying trade-versus-investment classification. A property investment company holding residential lettings is making investments, not conducting a trade, on the same Salisbury House Estates analysis that applies to individual landlords. Rollover relief under s.152 is unavailable on the same basis.

For property companies, the chargeable gain on disposal is computed under the Corporation Tax framework (Corporation Tax Act 2009 + Corporation Tax Act 2010) and taxed at the company's overall CT rate. Companies pay Corporation Tax on chargeable gains, NOT CGT. For 2026/27:

  • 19% small profits rate on profits up to £50,000
  • 25% main rate on profits above £250,000
  • Marginal relief tapers between £50,000 and £250,000

Most property investment SPVs are Close Investment-Holding Companies under section 18N CTA 2010, which excludes them from the small profits rate. CIHC SPVs pay at the main 25% rate on the full chargeable gain. Trading-status property companies (genuine developers with evidenced trading activity) sit in a different framework: the property is trading stock not a capital asset, and a sale produces a trading profit not a chargeable gain.

The CIHC mechanics and the asset-sale-vs-share-sale comparison are in the BTL limited company complete guide.

Former FHL property post-abolition

The Furnished Holiday Lettings regime was abolished by Finance Act 2025 Schedule 5 with effect from 6 April 2025. The CGT-side consequences for rollover relief:

  • Pre-6-April-2025 disposals: qualifying FHL businesses could claim s.152 rollover where the FHL met the operational conditions (210 days available, 105 days actually let, average lets under 31 days). Anti-forestalling rules closed routes that attempted to crystallise pre-abolition disposals artificially in the announcement-to-abolition window.
  • Post-6-April-2025 disposals: former FHL property is taxed as standard residential rental. The 'quasi-trading' classification ended with the regime. The property is investment-class on the Salisbury House Estates analysis. Rollover under s.152 is not available.
  • Cross-cut-off disposals: a disposal completing before 6 April 2025 retained the FHL CGT treatment; a disposal completing after that date does not. The disposal date for CGT is the completion date (or the contract date if unconditional and earlier).

The grandfathered position on remaining FHL features (BADR transitional, capital allowances grandfathering, ongoing implications for in-flight depreciation pools) is in the Wave 6 FHL grandfathered claims guide. For income-side post-abolition framing see the rewritten PRR for landlords guide for PRR interaction.

Alternative CGT reliefs for landlords who don't qualify

For the standard BTL landlord, the lever set when s.152 rollover is closed:

  • Private Residence Relief (s.222): covers the proportion of ownership when the property was the owner's main home, plus the final 9 months. See the PRR for landlords guide.
  • £3,000 annual exempt amount per individual: applies to the residual taxable gain. Spouse-share stacking via s.58 doubles the AEA on a single disposal. See the AEA depth guide.
  • Spouse rate-band split (s.58): pre-sale transfer to a basic-rate spouse can shift part of the gain from 24% to 18% on the rate gap. See the spouse transfer guide.
  • Capital loss offset (s.16): brought-forward losses (claimed within four years per TMA 1970 s.43) can be set against the chargeable gain. See the capital losses guide.
  • EIS deferral (Schedule 5B): the only deferral route that works on any chargeable gain regardless of asset class. Defers CGT by subscribing for qualifying EIS shares within the 12-months-before to 36-months-after window. See the CGT deferral guide.
  • Incorporation relief (s.162): available for active portfolio landlords meeting the going-concern test (Ramsay v HMRC [2013]). Transfers the property business to a company in exchange for shares, rolling the CGT gain into the shares' base cost. See the BTL limited company guide.
  • Timing levers: tax-year straddling and disposal-date alignment with income-cycle low-points can keep more of the gain in the basic-rate band at 18%. See the reduce CGT survey.

Future-rate context for deferred gains

A deferred rollover gain crystallises at the rates in force in the year of crystallisation, not at the rates in force in the year of the original disposal. For individuals in 2026/27, the residential property CGT rates are 18% (basic rate) and 24% (higher rate) on the chargeable gain after reliefs and AEA.

The property income tax rates announced at the Autumn Budget 2025 (22% basic / 42% higher / 47% additional rate from April 2027) were enacted in Finance Act 2026 (Royal Assent 18 March 2026). Those rates apply to property INCOME, not to CGT: the 18% / 24% CGT rates on residential property are not affected by the 2027 income-tax change and remain in force through 2027/28 on current law. Any longer-term CGT-rate change would require a separate Budget announcement.

Rollover deferrals on long horizons (rolled into a replacement asset held for 10+ years) need to factor in rate-uncertainty risk: a deferred 24%-rate gain could crystallise at a different rate depending on future Budget policy. The SDLT additional dwellings surcharge increased to 5% from 30 October 2024 under the Autumn Budget 2024 changes, affecting the net cash cost of reinvestment in further residential property.

Records, reporting and the deferred gain

Rollover claims are made on the SA108 capital gains pages of the Self Assessment return. The claim is not automatic; the taxpayer must elect to apply s.152 with reference to the relevant disposal and replacement assets. The records to retain include:

  • Disposal documentation: contract, completion statement, legal invoices, agent invoices, valuation
  • Replacement asset acquisition documentation: contract, completion statement, SDLT return and receipt, legal invoices
  • Evidence of trade use: contemporaneous business records, accounts showing the trade activity, photographs and floor plans showing the trade use, employment contracts for staff working from the premises
  • Badges-of-trade evidence (for developers): business plan, finance documentation, planning permissions, multiple transactions over time, sale-and-marketing records
  • The rollover claim itself: the SA108 claim plus the supporting computation showing the rolled-over gain, the base-cost adjustment to the replacement asset, and the residual chargeable amount (if partial relief)

The deferred gain re-enters the calculation when the replacement asset is eventually disposed of. The replacement asset's base cost is the actual cost less the rolled-over gain. Retain the rollover documentation indefinitely while the deferred gain is live, because the calculation on the replacement asset's eventual disposal needs the original rollover figures.

HMRC standard retention requirements are 22 months after the end of the tax year for non-business taxpayers and five years and 10 months for business taxpayers. For rollover-active records, retain indefinitely while any deferred gain remains attached to a replacement asset.
