Introduce Capital Gains Tax Relief for Landlords Selling to Tenants
Conservative · what the evidence says
An independent, source-checked look at Conservative’s policy “Introduce Capital Gains Tax Relief for Landlords Selling to Tenants” — what it would actually do across the things that affect your life. Every claim below quotes the source behind it. How this works.
Affordable housing — Mixed picture
minor · moderate confidence
This policy gives landlords a tax break to sell to their existing tenants, which could help some renters buy their home — but the government's own cost estimate suggests very few transactions will actually happen, and many tenants still can't afford to buy even with a discount.
The evidence
- The policy introduces a two-year temporary CGT relief for landlords who sell to existing tenants. — conservatives.com (manifesto) — “introduce a two-year temporary Capital Gains Tax relief for landlords who sell their properties to their existing tenants”
- The policy is designed to help tenants become homeowners and free up housing stock. — landlordtoday.co.uk (media) — “The policy is designed to "free up more housing stock"”
- Current CGT rates on residential property are 18% for basic-rate and 24% for higher-rate taxpayers on gains above £3,000. — landlordassociation.org.uk (media) — “current CGT rates on residential property for 2025/26 are 18% for basic-rate taxpayers and 24% for higher and additional-rate taxpayers on gains above the £3,000 annual exempt amount”
- The policy is estimated to cost only £20 million a year, implying very limited uptake. — landlordtoday.co.uk (media) — “The Conservative manifesto estimates the policy will cost £20 million a year, implying a relatively limited uptake”
- A CGT relief could save landlords around £15,000 per property on average, potentially shareable with tenants. — thenegotiator.co.uk (media) — “a 100% CGT relief for landlords selling to a long-term tenant could lead to an average CGT saving of £15,000 per property, which could potentially be shared, gifting both landlord and tenant £7,500 each”
- Many tenants are not in a financial position to purchase their rented property even with a potential saving. — todaysconveyancer.co.uk (media) — “many tenants not being in a financial position to purchase their rented property, even with a potential saving”
Biggest unknown: Whether tenants can actually afford to purchase their rented property, even if the landlord passes on part of the CGT saving.
Our reading: This policy creates a financial incentive for landlords to sell directly to sitting tenants by removing their CGT liability for a two-year window. For the small number of transactions it does facilitate, it could meaningfully help tenants onto the housing ladder — the CGT saving is substantial enough (averaging around £15,000) that some of it could be passed on as a price reduction. There is also a supply-side logic: properties sold to owner-occupiers are removed from the rental market, which could modestly free up other stock or reduce landlord concentration. However, the verdict is mixed rather than clearly positive for two reasons. First, the scale is negligible: the £20m annual cost estimate implies only a few hundred transactions per year across the entire country, so the aggregate impact on housing affordability is tiny. Second, the policy does nothing for the many renters who cannot afford to buy regardless of a tax-break-funded discount — those on lower incomes, in high-cost areas, or without mortgage eligibility are entirely excluded. The policy thus benefits a narrow, relatively better-off subset of tenants (those who can get a mortgage on their current home). It does not add to social or affordable housing stock, does not affect rents for non-purchasing tenants, and does not address the structural supply shortage. The net effect on O1 is real but very minor and concentrated on a small cohort.
Tax & the money you keep — Helps
minor · moderate confidence
Landlords who sell to existing tenants would pay no CGT on those gains, directly raising the money they keep from the sale. However, the policy is estimated to cost only £20 million a year, meaning very few households are affected at population scale.

Biggest unknown: Whether and how much of the tax saving landlords pass on to tenants through a lower sale price, and whether tenants can actually afford to buy at all.
Our reading: The policy directly reduces the CGT liability of landlords who sell to sitting tenants, raising the net proceeds they keep from the transaction — a clear O11 improvement for that group. At current rates of 18–24% on gains above £3,000, the relief is financially meaningful per transaction, with one estimate suggesting savings of around £15,000 per property. However, the policy's own costings imply only a small number of transactions will occur annually (£20m at roughly £15,000 saving per sale implies roughly 1,300 transactions a year at most). This is a real but narrow benefit concentrated among a small subset of landlords. The O11 gain to tenants is conditional and uncertain: it depends on landlords passing savings through as a price discount, which is not guaranteed and is not a stated policy requirement. Many tenants also lack the financial capacity to buy regardless, further limiting reach. The policy does not affect the broader tax burden of the general household population. On balance, the direction is a genuine O11 improvement — landlords in scope keep more of their gains — but the magnitude is minor because the population affected is very small. The IFS and Resolution Foundation advocate for broader CGT reform rather than targeted reliefs of this kind, but those are reform preferences rather than evidence that this specific measure fails to deliver its narrow tax benefit to those who use it.
Public finances & the next generation — Hurts
minor · low confidence
This policy reduces tax revenue without an offsetting funding source, worsening the fiscal position by a small amount. At the manifesto's own estimated cost of £20 million a year, the impact on public finances is real but very limited.
The evidence
- The policy is a two-year temporary CGT relief for landlords selling to existing tenants. — conservatives.com (manifesto) — “two-year temporary Capital Gains Tax relief for landlords who sell their properties to their existing tenants”
- CGT rates on residential property are 18% for basic-rate taxpayers and 24% for higher-rate taxpayers on gains above the £3,000 annual exempt amount. — landlordassociation.org.uk (media) — “current CGT rates on residential property for 2025/26 are 18% for basic-rate taxpayers and 24% for higher and additional-rate taxpayers on gains above the £3,000 annual exempt amount”
- The Conservative manifesto estimates the policy will cost £20 million a year, implying limited uptake. — landlordtoday.co.uk (media) — “The Conservative manifesto estimates the policy will cost £20 million a year, implying a relatively limited uptake”
- Limited uptake is partly expected because many tenants cannot afford to purchase even with the saving. — todaysconveyancer.co.uk (media) — “many tenants not being in a financial position to purchase their rented property, even with a potential saving”
- No direct OBR assessment of this specific relief is available in the evidence. — landlordtoday.co.uk (media) — “the search results do not contain a direct OBR report or statement specifically detailing their assessment of this particular relief”
Biggest unknown: Whether the £20m annual cost estimate is accurate — if uptake were significantly higher than assumed, the revenue cost would rise proportionally.
Our reading: This policy reduces CGT receipts for a defined group of landlords without any stated offsetting measure, making it an unfunded tax expenditure. The manifesto's own costing of £20m/year over two years gives a total fiscal cost of roughly £40m — very small by public-finance standards. Because uptake is expected to be limited (partly because many tenants cannot afford purchase even with the saving), the revenue loss stays contained. There is no evidence that the policy generates offsetting fiscal returns — for example through stamp duty receipts or reduced housing-benefit costs — at a scale that would neutralise the cost; no such mechanism is cited in the evidence. The IFS and Resolution Foundation flag broader CGT as often under-reformed, but neither body has assessed this specific measure. On the dual-horizon test: the relief is temporary (two years), so the fiscal drag is time-limited; there is no long-term debt-path concern at this scale. The verdict is 'worsens/minor': it is a genuine, if small, deterioration in the fiscal position — an unfunded tax cut — but not one that moves the debt path at population scale. Confidence is low because the OBR's view is not available in the evidence and the cost estimate's reliability cannot be verified from the provided sources.
Inequality & fair shares — Little effect
minor · low confidence
This policy gives landlords a CGT tax break to encourage sales to sitting tenants, but the estimated cost of only £20 million a year implies very few transactions will actually happen. At that scale it cannot meaningfully move the needle on overall income or wealth inequality.
The evidence
- The policy introduces a two-year temporary CGT relief for landlords who sell to existing tenants. — conservatives.com (manifesto) — “introduce a two-year temporary Capital Gains Tax relief for landlords who sell their properties to their existing tenants”
- CGT rates on residential property are 18% for basic-rate taxpayers and 24% for higher and additional-rate taxpayers. — landlordassociation.org.uk (media) — “current CGT rates on residential property for 2025/26 are 18% for basic-rate taxpayers and 24% for higher and additional-rate taxpayers on gains above the £3,000 annual exempt amount”
- The financial benefit of the relief flows primarily to landlords, not tenants. — mylondonhome.com (media) — “Landlords stand to gain significant financial savings by being exempt from CGT, which could increase the profitability of selling to their tenants compared to an open market sale”
- A think-tank estimate suggested the CGT saving could average £15,000 per property and could in principle be shared with the tenant. — thenegotiator.co.uk (media) — “a 100% CGT relief for landlords selling to a long-term tenant could lead to an average CGT saving of £15,000 per property, which could potentially be shared, gifting both landlord and tenant £7,500 each”
- The policy is estimated to cost only £20 million a year, implying very limited uptake. — landlordtoday.co.uk (media) — “The Conservative manifesto estimates the policy will cost £20 million a year, implying a relatively limited uptake”
- Many tenants are not in a financial position to purchase even with a potential saving, further limiting uptake. — todaysconveyancer.co.uk (media) — “many tenants not being in a financial position to purchase their rented property, even with a potential saving”
Biggest unknown: Whether any CGT saving is passed on to tenants as a price discount, or retained by landlords, determines which way the small distributional effect runs.
Our reading: The policy has two distributional forces pulling in opposite directions. On the worsening side, the immediate and certain financial gain is the landlord's CGT exemption — landlords as a group hold substantially more wealth than their tenants, so a targeted tax break for them modestly skews the tax system in favour of asset-holders. On the improving side, some tenants who do complete a purchase cross the ownership threshold, narrowing the wealth gap for those individuals; and there is a theoretical possibility the CGT saving is partially passed through as a price discount. However, the policy's own projected cost of £20 million a year signals that the number of transactions affected is very small. At that scale neither the landlord-benefiting nor the tenant-homeownership effect can plausibly shift population-level inequality indicators such as the Gini coefficient or the homeownership gap in any measurable way. The further constraint noted in the evidence — that many tenants simply cannot afford to buy — further caps the upside. Because the scale is demonstrably tiny, the directional ambiguity (who captures the saving) is less important than the magnitude floor: this policy does not approach the threshold needed to move the fundamental's indicators at population scale. The verdict is therefore negligible rather than mixed, with low confidence because the pass-through question remains unresolved and no independent distributional modelling is available in the provided evidence.
