FHL Capital Allowances Post-April-2025: The Grandfathered Pool Mechanics and the Disposal Balancing-Charge Trap

The furnished holiday lettings regime ended in March and April 2025 but the capital allowances side of the abolition is not a clean cut-off. Finance Act 2025 Schedule 5 Part 5 paragraph 18 preserves the plant-and-machinery pool balances that existed on the FHL business at commencement, lets them continue writing down at the ordinary 18 per cent main pool and 6 per cent special-rate pool reducing-balance rates, and explicitly carves them out of the Capital Allowances Act 2001 s.35 dwelling-house restriction so the historic claim does not unwind. New post-commencement spend on the same property is a different story: the property is now an ordinary UK or overseas property business, the s.35 bar applies in full, and most new P&M spend in a dwelling has lost its allowance route. The most operationally important point for sale-planning operators is the balancing-charge trap that bites on disposal of a former-FHL property while the grandfathered pool is still active.

This page walks the FA 2025 Sch 5 architecture and confirms the correct citation (the FHL Schedule is FA 2025 Sch 5, not FA 2024 Sch 5, which addresses museums and gallery exhibitions), the paragraph 18 grandfathered-pool transitional, the s.35 bar on post-commencement spend on the same property, the disposal balancing-charge mechanic and a worked £45,000 pool example, the Part 4 CGT preservation for BADR and investors' relief, the Parts 1 and 2 loss-relief transitional, and three planning patterns for former-FHL operators in 2026/27.

The FA 2025 Sch 5 architecture and the commencement gate

Finance Act 2025 Schedule 5 is the FHL abolition Schedule. The Act received Royal Assent in March 2025 and is on the statute book in its enacted form. The Schedule has five Parts: Part 1 amends income tax provisions consequent on abolition; Part 2 amends corporation tax provisions; Part 3 amends capital allowances provisions and includes the central omissions at CAA 2001 s.15(1)(c) (UK FHL) and s.15(1)(da) (EEA FHL) from the qualifying-activity list; Part 4 amends chargeable gains provisions to preserve BADR and investors' relief on qualifying transitional disposals; Part 5 contains the commencement provisions and the operational transitional rules.

The commencement date for the capital allowances amendments is at Part 5 paragraph 12(3): "for the purposes of corporation tax, in relation to accounting periods beginning on or after 1 April 2025, and for the purposes of income tax, in relation to periods of account beginning on or after 6 April 2025." The dating splits between CT and IT in the conventional way, with the CT date keyed to the operator's accounting period start and the IT date keyed to the operator's tax year start.

The single most common citation error on FHL abolition is to attribute the abolition to Finance Act 2024 Schedule 5. That citation is wrong; FA 2024 Sch 5 addresses an unrelated reform on museums and gallery exhibitions tax relief. The error has appeared in pre-Royal-Assent draft commentary, in some HMRC manual indices in the early post-Assent period, and in third-party briefings published before the Act's Royal Assent. The authoritative reference is the legislation.gov.uk text of FA 2025 Sch 5, which was verified on 23 May 2026.

The paragraph 18 grandfathered-pool mechanic

FA 2025 Sch 5 Part 5 paragraph 18 contains the preserving transitional for plant-and-machinery pool balances that existed at commencement. The provision in summary: where a person was carrying on an FHL business at commencement and had qualifying expenditure allocated to a plant-and-machinery pool in respect of that business, the unrelieved pool balance is carried forward to the person's post-commencement chargeable period and allocated to the corresponding ordinary property business pool. The corresponding pool is the UK property business main pool for a former-UK-FHL main-pool balance, the UK property business special-rate pool for a former-UK-FHL special-rate-pool balance, and the equivalent overseas property business pools for former-EEA-FHL balances.

The carried-forward expenditure continues writing down under the ordinary CAA 2001 Part 2 mechanics at 18 per cent reducing balance for main pool items and 6 per cent reducing balance for special-rate pool items. The chargeable-period allowance is computed on the pool TWDV at the start of the period, with disposals reducing the pool and writing-down allowance reducing the carry-forward balance. The mechanic is unchanged from the pre-abolition framework other than the rebrand from FHL pool to property business pool.

The critical drafting at paragraph 18 is the explicit carve-out from the CAA 2001 s.35 dwelling-house restriction for the grandfathered expenditure. Without the carve-out, the moment the FHL business ceased to be a separate qualifying activity, the property became plant in a dwelling-house carried on as a property business, and s.35 would have barred the continuation of any pool balance. The paragraph 18 carve-out forecloses that result: the historic claim does not unwind, the pool balance continues to be deductible against property business profits, and the writing-down allowances continue accruing until the pool has fully written down or the property is disposed of.

Post-commencement new spend on the same property

Paragraph 18's carve-out applies to the carried-forward grandfathered expenditure. It does not apply to new expenditure incurred post-commencement. New expenditure on the same former-FHL property after 1 April 2025 (CT) or 6 April 2025 (IT) is expenditure on plant or machinery for use in a dwelling-house, and CAA 2001 s.35 applies in full to bar the plant-and-machinery allowance.

The relief route for replacements of domestic items in the former FHL is now the ITTOIA 2005 s.311A replacement of domestic items relief, which gives a revenue deduction in the period of incurring for the cost of replacing furniture, furnishings, appliances and kitchenware provided for tenants. The relief applies regardless of the FHL-or-not status of the property; it was always available for ordinary residential lettings and is now the standard post-abolition route for former-FHL replacement spend. The relief is on a revenue basis (one-shot deduction in the year of replacement), not on a capital-allowances writing-down basis. First-time provision of items (rather than replacement) does not qualify.

The narrow exception is plant in genuine common parts of a multi-occupied building under the s.35 carve-out. A self-catering holiday cottage is a single dwelling with no common parts, so the exception does not apply. A multi-unit holiday let development (e.g. a holiday park with self-contained units around shared facilities) may have genuine common parts in the shared blocks; our bucket sibling page on HMO and multi-let common parts walks the s.35 boundary analysis.

The disposal balancing-charge trap

When a former-FHL property is disposed of after commencement while the grandfathered pool is still active, CAA 2001 s.61 brings a disposal value into the pool computation. The disposal value depends on the event: a sale at market value brings in the just-and-reasonable apportionment of the sale price attributable to the fixtures, subject to a ceiling of the original cost of the relevant expenditure. The disposal value is set against the pool's AQE (available qualifying expenditure) under s.55. Where the disposal value exceeds AQE, the difference is a balancing charge, taxed as a property business receipt in the disposal period.

A worked example. Anonymised operator Mr Bell incurred £45,000 of qualifying plant-and-machinery expenditure on his former-FHL property over the years 2018 to 2022, claimed in full via AIA at the time and reflected as a written-down balance in the main pool. By the 2026/27 sale date, the pool's tax-written-down value has dropped to £18,000 (after several years of 18 per cent reducing-balance writing-down). Mr Bell sells the property for £580,000 in November 2026. The sale agreement contains no s.198 election. The just-and-reasonable apportionment of the £580,000 sale price attributable to the fixtures is £35,000, ascertained by a quantity surveyor's report commissioned by Mr Bell to defend the position on enquiry. The disposal value brought to account is £35,000 (capped at the £45,000 original cost, so the cap does not bite).

The balancing-charge computation: AQE in the pool is the £18,000 TWDV at the start of the disposal period, plus any new additions (nil here because s.35 barred new spend post-commencement). TDR (total disposal receipts) is the £35,000 disposal value. TDR minus AQE is £17,000, which is the balancing charge brought to account as a property business receipt in the 2026/27 disposal period. At a higher-rate marginal tax rate of 40 per cent, Mr Bell faces a £6,800 income tax charge on the £17,000 balancing charge. At an additional-rate marginal tax rate of 45 per cent (or 47 per cent under the post-Autumn-Budget-2024 property income tax surcharge from April 2027), the charge is £7,650 or £7,990 respectively.

The planning mitigations: timing the sale into a year where the operator has property business losses to absorb the balancing-charge income (loss offset is on a same-year same-property-business basis); using a s.198 election with a co-operative commercial-grade buyer to fix the disposal value at the £18,000 TWDV and avoid the balancing charge entirely (uncommon on residential sales to private buyers, common on portfolio sales between sophisticated counterparties); or accepting the balancing charge as the working tax cost of the disposal and planning the rest of the deal around it.

The Part 4 CGT preservation: BADR and Investors' Relief

The chargeable gains side of FHL abolition is treated separately at FA 2025 Sch 5 Part 4. Pre-abolition, an FHL business was statutorily treated as a trade for certain CGT purposes including the application of business asset disposal relief at TCGA 1992 s.169H onwards (formerly entrepreneurs' relief) and investors' relief at TCGA 1992 s.169VA onwards. Post-abolition, the FHL is no longer deemed a trade, and a vanilla post-commencement disposal of a former-FHL property does not qualify for BADR or investors' relief on the trading-status route.

The Part 4 transitional preserves BADR and investors' relief for qualifying disposals where the underlying trading-status period predates the commencement date. The detailed mechanics are operationally complex and require attention to the conditions including the two-year qualifying-period rule, the personal-company test for BADR on share disposals, and the three-year holding period for investors' relief. The preservation applies on a per-disposal basis where the disposal is of (a) the FHL business as a going concern, (b) shares in a company that was carrying on an FHL business pre-commencement, or (c) assets used in the FHL business pre-commencement and disposed of within the three-year transitional window from commencement.

The BADR rate matters materially. Pre-30-October-2024 the rate was 10 per cent. From 6 April 2025 it steps to 14 per cent. From 6 April 2026 it steps to 18 per cent. The lifetime BADR allowance is £1m. For an FHL operator disposing in the 2026/27 tax year at the 18 per cent BADR rate (where the preservation applies) versus 24 per cent at the standard CGT residential rate, the differential is 6 percentage points or £6,000 per £100,000 of qualifying gain. Operators in the preservation window should not assume FHL CGT advantages are gone; the Part 4 transitional is real and material.

Loss-relief transitional: Parts 1 and 2

Pre-abolition unutilised FHL losses are absorbed into the ordinary property business loss pool under FA 2025 Sch 5 Parts 1 and 2 from commencement. Pre-abolition, an FHL loss had specific carry-forward and offset features: it could be treated as a trading loss for some sideways-loss purposes (subject to the loss restriction at ITA 2007 s.74A for non-active income), and it had a wider offset profile than an ordinary property business loss.

Post-commencement, the FHL loss is treated under the ordinary property business loss rules at ITA 2007 s.118 onwards (income tax) or CTA 2010 s.62 onwards (corporation tax). The loss is not destroyed; it is preserved and continues to be available against future property business profits. What is lost is the wider trading-loss offset profile for use against general income; from commencement, the loss is offset against property business profits only (with limited sideways-loss carve-outs that mirror the ordinary property business position).

A worked BADR preservation calculation

Anonymised operator Ms Carmichael ran a UK FHL business from 2018 through to the 5 April 2025 income tax commencement date. She ceased operating the FHL on commencement and held the property as an ordinary residential let from 6 April 2025 onwards. In December 2026 she sells the property for £820,000. Her original purchase cost in 2018 was £340,000, with capital improvements of £80,000 over the holding period. Her base cost is £420,000; her gross gain on sale is £400,000.

Without the FA 2025 Sch 5 Part 4 preservation, the gain would be taxed at the standard CGT residential rates: 24 per cent on most of the gain (after the £3,000 annual exempt amount for 2026/27), so approximately £95,280 of CGT. With the Part 4 preservation, the disposal qualifies for BADR because Ms Carmichael ran the FHL business as a trade-deemed activity in the two-year period ending at commencement, and the disposal falls within the three-year transitional window from commencement.

The BADR rate applicable to a 2026/27 disposal is 18 per cent (the post-Autumn-Budget-2024 step from 14 per cent in 2025/26). BADR applies up to the £1m lifetime allowance per individual. Ms Carmichael has not previously used any BADR, so the full £400,000 gain falls within the lifetime allowance. After the £3,000 annual exempt amount, the chargeable gain at BADR is £397,000, taxed at 18 per cent equals £71,460 of CGT.

The BADR preservation saves Ms Carmichael £95,280 minus £71,460 equals £23,820 of CGT on the disposal, a 25 per cent reduction on the gross tax. The saving more than justifies the technical work required to evidence the Part 4 preservation conditions (the two-year qualifying-period through commencement, the trading-status of the FHL activity at commencement, and the three-year transitional window for the disposal). Operators in similar positions should not assume FHL CGT advantages are universally gone post-abolition.

Three planning patterns for former-FHL operators in 2026/27

The first planning pattern is the BADR preservation window. Operators whose trading-status period ended at or before commencement and who can plan their disposal within the three-year transitional window from commencement retain access to the 14 per cent BADR rate in 2025/26 or the 18 per cent BADR rate in 2026/27 (versus 18 per cent / 24 per cent at the standard CGT rates for residential). The differential is material on a £500,000-plus qualifying gain. The pattern requires careful attention to the trading-status period definition and the three-year window from commencement.

The second planning pattern is balancing-charge timing into a low-marginal-income year. Operators with a grandfathered pool still active should plan the disposal of the former FHL into a year where they have property business losses to absorb the balancing-charge income, or where their marginal income tax rate is lower (e.g. a year between two employments, or a year of pension consolidation). The balancing charge is a property business receipt and is taxed at the operator's marginal rate in the disposal period, so the timing optimisation can save material income tax.

The third planning pattern is incorporation. Moving the former-FHL rental activity into a corporate vehicle subject to corporation tax (currently 19 to 25 per cent depending on profit level, with marginal-rate relief between £50k and £250k profit) can be tax-efficient where the individual operator is in a higher-rate or additional-rate income tax band. Incorporation triggers SDLT on the deemed market-value disposal (no FHL incorporation relief now), so the SDLT cost has to be factored. CGT incorporation relief at TCGA 1992 s.162 may be available if the property business meets the trade-test for that section (unlikely for a self-catering FHL, possible for a serviced accommodation operator). The grandfathered plant pool balances transfer to the new corporate vehicle on incorporation. Our existing page on transferring an FHL portfolio to a limited company walks the incorporation mechanics post-abolition.

Where this page sits in the Bucket C cluster

This page is the post-abolition FHL capital allowances depth page for the Bucket C cluster. It sits downstream of the pillar page C1 on capital allowances for property investors, which establishes the four-axis decision framework and identifies the s.35 dwelling-house restriction as the cluster's central misconception. It draws on the C2 disposal-mechanics page for the s.61 balancing-value framework, on the C3 SBA page for the s.270CF residential exclusion that always excluded FHL SBA, and on the C7 common-parts page for the narrow s.35 carve-out.

The analysis applies for chargeable periods ending in 2026/27 onwards. The Finance Act 2025 Schedule 5 commencement at 1 April 2025 (CT) / 6 April 2025 (IT) is the working starting date. The paragraph 18 grandfathered-pool transitional, the s.35 bar on post-commencement new spend, the s.61 disposal-value mechanic and its balancing-charge consequence, the Part 4 CGT preservation for BADR and investors' relief on transitional disposals, and the Parts 1 to 2 loss absorption are all verified against the legislation.gov.uk text on 23 May 2026.
