VAT on domestic electricity drops from 5% to 0% from 1 October 2026 to 31 March 2027. For a five-bed HMO using 10,000 kWh of electricity per year, removing the 5% VAT cuts the annual electricity bill by around £103. Modest in isolation. Across a ten-property HMO portfolio, that is over £1,000 in the second half of this financial year. Budget accordingly, and do not treat it as permanent.
What Has Happened?
On 21 July 2026, the UK government announced that VAT on domestic electricity supplies would be reduced from the current 5% rate to 0% from 1 October 2026. The measure applies until 31 March 2027, covering six months of the financial year. The Treasury estimated the policy would cost approximately £850 million during 2026-27.
The cut applies to domestic electricity only. Gas supplies remain at the 5% reduced VAT rate. The government's stated rationale was to reduce cost-of-living pressure, and the average quoted household saving was roughly £45 per year. Over the six-month October to March window, the equivalent per-household figure is approximately £22 to £23.
The policy applies to all supplies that currently qualify for the reduced 5% rate. That includes domestic electricity, residential accommodation, care homes, and hospices. Suppliers must pass the saving on to all customers, including those on fixed-rate tariffs agreed before the July announcement. Northern Ireland is excluded. The government confirmed comparable funding would be provided to the Northern Ireland devolved administration by separate arrangement.
For residential landlords in England, Scotland, and Wales, the practical question is whether the saving reaches them at all. That depends entirely on how electricity is handled within the tenancy arrangement, not on where the property sits in the market.
Why This Matters to UK Property Investors
The impact of this policy splits cleanly into two groups. Standard BTL landlords with single-let tenancies under the Renters' Rights Act periodic tenancy framework, where the tenant holds the utility account in their own name and pays the energy supplier directly, see nothing. The VAT saving goes straight to the tenant via a lower electricity bill from their supplier. There is no benefit to the landlord. I am in this position on most of my personally held single-lets, and that is the honest answer.
HMO landlords running all-inclusive or bills-included tenancy arrangements are the group this actually affects. If you pay the household electricity supplier directly and price your inclusive rent to cover it, you carry the electricity cost. From 1 October, that cost falls. The question is how much.
UK domestic electricity prices in 2026 average around 26 to 28 pence per kWh, inclusive of the current 5% VAT. A five-bed HMO with working professionals and reasonable energy habits might use 8,000 to 10,000 kWh of electricity per year. At 27p/kWh, the annual bill runs around £2,160. The VAT component within that is approximately £103. Over the six-month October to March window, the saving is roughly £51 on that property.
At 15,000 kWh per year, which is more typical of a five or six-bed HMO in a colder northern city where occupants are home more and supplement heat with electric appliances, the annual saving at 5% VAT is around £154, or £77 over six months. At 20,000 kWh, the annual saving is £257, meaning £128 in the October to March window.
Those individual property figures are not transformational. Across a portfolio of ten HMOs, the six-month saving ranges from roughly £500 to £1,280 depending on usage. That covers several months of utilities management fees or part of an EPC improvement cost on one property. In the same six months where landlords are absorbing compliance costs under the Renters' Rights Act and where mortgage rates remain above 5%, every reduction in operating cost has somewhere to go.
There is one more category worth naming. Landlords who operate serviced accommodation or short-term lets on assured shorthold tenancy arrangements, where the landlord controls the utility accounts directly, also qualify for the zero rate on electricity from October. The saving calculation is the same as for HMOs, scaled to the property's annual consumption. Properties with high occupancy rates and continuous electricity demand (air conditioning in warmer months, high-frequency appliance use) will sit toward the upper end of the usage range.
The Risks Investors Need to Understand
The biggest risk is treating this as a permanent structural change to operating costs. The measure runs from 1 October 2026 to 31 March 2027. Nothing in the government's announcement committed to extending it. An autumn Budget could extend the period. Equally, it could lapse at the end of March 2027 with the VAT rate reverting to 5%. Any landlord who restructures their all-inclusive rent pricing downward on the assumption of zero-VAT electricity in perpetuity is building in a future cost increase at exactly the point when the measure ends.
Gas is not included. This matters for a large proportion of the HMO portfolio in the UK. Most pre-2000 terraced housing in northern cities, which is where the bulk of England's HMO stock sits, is gas-heated. For a five-bed HMO in a Leeds LS6 terrace where annual energy costs split roughly 60% gas and 40% electricity, the overall energy bill saving from October is approximately 2%, not 5%. The gas bill continues unchanged. Landlords who have been loosely tracking "energy costs" without separating gas and electricity will need to do that work before they can calculate the actual benefit.
Northern Ireland landlords gain nothing directly. The government's announcement excluded Northern Ireland explicitly. The comparable funding is a transfer to the devolved administration, not a VAT cut at the point of supply. If you hold HMO property in Belfast, the October change does not apply to your electricity bills.
Fixed-rate tariff complications could delay the saving for some. HMRC's position is that the zero rate applies from 1 October regardless of when the tariff was agreed. Some energy suppliers have been slow to implement legislative VAT changes in the past. Check your October electricity invoice to confirm the VAT rate applied. If it still shows 5%, that is a supplier error. Challenge it.
For landlords considering re-setting inclusive rent at a slightly lower level to pass the electricity saving on to tenants, the trade-off is permanent versus temporary. Inclusive rent reductions that become market expectations are hard to reverse when VAT reverts to 5% in April 2027. Better to hold inclusive rent at current levels, absorb the saving as margin for six months, and review the position once the government confirms whether the measure will be extended.
Where the Opportunity Could Be
The immediate application is operational. HMO landlords paying electricity bills who have not been tracking consumption per property now have a financial reason to do so. Knowing your actual kWh usage per HMO means you can calculate exactly what the October saving amounts to for that property. It also gives you baseline data for future EPC improvements, where reducing energy consumption reduces the ongoing electricity bill regardless of VAT rate. A landlord who monitors consumption monthly will also catch billing errors faster, which is separately valuable.
The second use case is competitive positioning on inclusive rent. In cities with dense HMO supply, including Nottingham NG7, Leeds LS6, and Manchester M14, pricing matters at the margin. A landlord whose electricity costs fall by 5% from October has slightly more room to offer competitive all-inclusive room rates during void windows without cutting into margin. The national average rental void period fell to 21 days in August 2026, down from 24 days in May. That improvement happened because supply remains constrained. But in postcode patches with several HMOs competing for the same tenant pool, a £10 to £20 monthly price advantage on an all-inclusive room is still meaningful during a fill window.
Third, for investors currently doing due diligence on HMO acquisitions, underwriting with post-October electricity costs (zero VAT) rather than current costs (5% VAT) slightly improves the modelled net operating income for the period to March 2027. On a property you are completing in September or October, all six months of the measure benefit your first trading period. Model it as upside rather than base case, but it is a real number.
Longer view: the government framed residential accommodation alongside care homes and hospices in the list of qualifying supplies for this measure. That framing matters because it confirms the policy intent is to treat the residential accommodation sector, including HMOs and supported living arrangements, as qualifying for domestic energy treatment. If zero-rate electricity becomes politically durable, the HMO operators best placed to benefit are those who have already invested in energy efficiency, because their consumption is lower and the per-unit saving compounds across a smaller electricity bill. An HMO at EPC B or above using 7,000 kWh per year saves less in absolute terms than a D-rated property using 18,000 kWh, but its lower running costs are more defensible across any future energy policy environment.
Arsh's Investor View
The VAT cut is a small net positive for HMO operators and a non-event for standard BTL landlords with tenants managing their own energy accounts. I am not restructuring any strategy around it.
What I find more interesting is the framing. Andy Burnham's government placed residential accommodation, including HMOs, on the same qualifying footing as care homes in the scope of this measure. That is not accidental language. If there is a future policy review of how energy VAT applies across the residential spectrum, that framing is the government's own starting point. It does not guarantee anything. But it suggests the policy direction is toward treating residential accommodation as domestic rather than commercial for energy cost purposes, which is the correct treatment if the policy goal is reducing the cost of housing in the UK.
Practically, I would do two things before October. Read the electricity meters on every HMO property I own, so I have an accurate baseline to compare against the October bills. And check that the energy supplier for each property has acknowledged the October VAT change. Some suppliers have been slower to update their systems for VAT rate changes than HMRC requires. If the October bill arrives at 5% VAT, I want to know before November, not six months later when I am trying to reconcile accounts for the financial year.
Gas being excluded is the bit I keep coming back to. Most of my northern portfolio is gas-heated, as most of the UK's HMO stock is. The electricity saving is genuine. It is also the smaller of the two utility costs in a cold winter. Anyone who has run an all-inclusive HMO through a January and February in Leeds or Manchester knows that the gas bill in those months outweighs the electricity bill substantially. The October measure helps with one of those bills and not the other. Worth knowing clearly before you start projecting savings.

Key Takeaways
- VAT on domestic electricity is reduced from 5% to 0% from 1 October 2026 to 31 March 2027. Announced by the Andy Burnham government on 21 July 2026. Estimated cost to the Treasury: £850 million in 2026-27. Average household saving: approximately £45 per year across twelve months, or £22 to £23 over the six-month measure window. Northern Ireland excluded. Gas supplies remain at 5% VAT, unchanged.
- HMO landlords operating all-inclusive or bills-included tenancy arrangements are the PRS group most directly affected. Where the landlord is the electricity account holder, the 5% to 0% VAT reduction reduces their electricity cost from 1 October. Savings by consumption: 10,000 kWh per year property saves approximately £103 annually (£51 over six months); 15,000 kWh per year saves approximately £154 annually (£77 over six months); 20,000 kWh per year saves approximately £257 annually (£128 over six months).
- Standard BTL landlords with tenants who hold their own energy accounts receive no direct benefit. The saving goes to the tenant via a lower electricity bill. Gas-heated properties see a smaller overall energy cost reduction: where gas accounts for 60% of annual energy costs and electricity 40%, the total energy bill saving from October is approximately 2%, not 5%.
- The measure is explicitly temporary (October 2026 to March 2027). Do not model it as a permanent cost reduction. Do not restructure inclusive rent downward on the assumption of zero VAT on electricity after March 2027. Hold current rent levels and absorb the saving as improved margin for the six-month window. Review the position once the government confirms its Budget plans for the measure.
- Practical actions before October: read electricity meters on all HMO properties to establish a consumption baseline; check that energy suppliers have acknowledged the VAT rate change; track October bills to confirm 5% VAT has been removed. Suppliers are legally required to pass on the saving to all customers including those on fixed-rate tariffs. A bill arriving in October at 5% VAT is a supplier error and should be challenged.
Frequently Asked Questions
Does the 0% VAT on electricity from October 2026 apply to HMO landlords?
Yes. The government's measure applies to domestic electricity supplies and residential accommodation, which includes houses in multiple occupation. Where the landlord holds the electricity account and pays the energy supplier directly, the 5% to 0% VAT reduction applies to that landlord's electricity bills from 1 October 2026. In all-inclusive HMO tenancy arrangements where the landlord recovers electricity costs through inclusive rent, the October change reduces the landlord's direct electricity cost and improves their operating margin. Tenants paying separately managed energy accounts through a utility management company may see a different treatment depending on how the supplier structures the VAT on that supply.
How much will an HMO landlord save on electricity from October 2026?
The saving depends on annual electricity consumption. UK domestic electricity prices in 2026 average approximately 26 to 28 pence per kWh including the current 5% VAT. At 27p/kWh, removing the 5% VAT reduces the unit cost by approximately 1.29p/kWh. For a five-bed HMO using 10,000 kWh per year, the annual saving is approximately £103, or £51 over the October to March six-month window. A six-bed HMO using 15,000 kWh per year saves about £154 annually, or £77 over six months. Properties using 20,000 kWh per year, typical of larger or less energy-efficient HMOs in colder locations, save approximately £257 per year, or £128 over the six-month measure period.
Does the VAT cut apply to landlords on fixed-rate energy tariffs?
Yes. HMRC's guidance confirms the zero VAT rate on domestic electricity applies from 1 October 2026 regardless of whether the energy tariff was agreed before or after the government's 21 July 2026 announcement. Suppliers are required to pass the saving on to all customers, including those locked into fixed-rate agreements. If an electricity invoice from October 2026 still shows 5% VAT, that is a supplier error. Landlords should challenge it with their supplier and refer to HMRC's published guidance on the measure if the supplier disputes the obligation. The saving does not require any action by the landlord beyond checking the October bill.
Does the VAT cut on electricity also reduce gas bills?
No. The October 2026 measure applies only to domestic electricity. Gas supplies remain at the 5% reduced VAT rate and are not affected by the announcement. For HMO landlords and BTL operators where gas central heating accounts for the majority of annual energy costs, the overall energy bill saving is materially smaller than the electricity saving alone. A property spending 60% of its annual energy budget on gas and 40% on electricity will see approximately a 2% total energy cost reduction from October, not the full 5% reduction that applies only to the electricity component.
Will 0% VAT on domestic electricity continue after March 2027?
The measure as announced runs from 1 October 2026 to 31 March 2027 only. The government made no commitment to extend it beyond that date. An extension could be announced in the autumn Budget, but it is not confirmed. Landlords should run financial models with 5% VAT on electricity as the base assumption from April 2027, treating the October to March window as a defined six-month saving rather than a structural change to operating costs. If the measure is extended in the Budget, that will improve margins for subsequent periods. If it reverts in April 2027, portfolios modelled on zero-rate electricity will face a modest cost increase.
