UK landlords must provide a fixed heating system capable of reaching 21°C in the main living room and 18°C in bedrooms. That is the legal minimum under the Housing Health and Safety Rating System (HHSRS). By 1 April 2028, new rental tenancies must also reach EPC band C under updated MEES rules, extending to all tenancies by 1 April 2030. For most landlords, that second requirement makes the type of heating system in the property a compliance question, not just a comfort one.
What Are Landlord Heating Requirements Under UK Law?
Landlords carry three overlapping legal duties on heating:
Landlord and Tenant Act 1985 (Section 11): Landlords must keep in repair the installations that provide heating and hot water. A broken boiler is a Section 11 disrepair and must be fixed promptly.
Homes (Fitness for Human Habitation) Act 2018: A property that cannot be kept adequately warm fails the fitness-for-habitation standard. Tenants can take landlords directly to court without waiting for council enforcement.
Housing Health and Safety Rating System (HHSRS): Excess cold is classified as a Category 1 hazard. When a council identifies one, it has a mandatory duty to act. Options include improvement notices, prohibition orders and emergency remedial action.
The temperature standard is specific: the property must be capable of reaching 21°C in the main living area and 18°C in bedrooms, with an external temperature of -1°C. Portable electric heaters do not meet this standard. The heating must be fixed and permanently installed.
Gas heating also requires an annual safety inspection under the Gas Safety (Installation and Use) Regulations 1998. The CP12 certificate must be given to tenants before they move in and within 28 days of each annual check. Failure to carry one out is a criminal offence.

How Does Your Heating System Affect Your EPC Rating?
Heating and hot water account for around 60 to 70 percent of a rental property's energy use, making the heating system the dominant variable in your EPC score. Insulation matters, but it is secondary.
Under the current RdSAP 10 assessment methodology, the ranking from best to worst EPC contribution runs roughly as follows:
| Heating System | EPC Band Contribution |
|---|---|
| Air source or ground source heat pump | Excellent (A/B range) |
| Modern condensing gas boiler with solar thermal | Good (B/C range) |
| Modern condensing gas boiler alone | Moderate (C/D, depending on property fabric) |
| Modern electric storage heaters | Below average (D/E) |
| Oil or LPG boiler | Poor (E/F) |
| Older electric storage heaters or panel heaters | Poor (E/F) |
| Solid fuel (coal/wood) | Worst (F/G) |
A property with excellent insulation but older electric storage heaters can still be stuck at band D or E. Conversely, a heat pump in an otherwise average property can pull it above the band C line.
What Is Changing for Landlord Heating Requirements by 2030?
The government confirmed its updated MEES policy in January 2026 (GOV.UK, January 2026). The key dates are:
- 1 April 2028: New tenancies must meet EPC band C (or equivalent under the new Home Energy Model).
- 1 April 2030: All existing tenancies must meet EPC band C.
Alongside those dates, the government confirmed a £10,000 cost cap per property. Landlords must spend up to £10,000 on qualifying improvements before they can register a cost cap exemption. Spending counts from 1 October 2025, so any work done now is already on the clock.
For properties worth less than £100,000, the cap adjusts to 10 percent of the property's current market value. A property worth £80,000 has an effective cap of £8,000.
Non-compliance under MEES carries penalties of up to £30,000 per property per breach.
What Changes Under the New Home Energy Model?
The new Home Energy Model (HEM), due to launch in October 2026, will replace RdSAP 10 as the standard assessment methodology. It introduces three separate metrics:
- Fabric Performance -- insulation quality and air tightness
- Heating System -- the type and efficiency of the installed heating system
- Smart Readiness -- energy tariff optimisation and smart controls
Under HEM, gas boilers are capped at band D on the Heating System metric. That does not automatically fail a gas-boiler property. But it does mean properties with gas heating need strong fabric or smart readiness scores to compensate.
Properties with heat pumps, heat networks or other low-carbon heating will score well on the Heating System metric and have a simpler path to band C overall.
Some properties that currently hold an EPC C certificate may fall below C when re-assessed under HEM. Getting a fresh assessment under current methodology before October 2026 may be worth considering for properties close to the band boundary.
Which Properties Are Most at Risk?
Based on heating system caps and fabric requirements under HEM, the properties most likely to need action are:
- Properties with old gas boilers and poor insulation (solid walls, no loft insulation) -- low scores on both Heating System and Fabric Performance
- Properties with electric storage heaters, particularly older models that perform poorly on energy efficiency metrics
- Properties with oil or LPG boilers -- high-carbon systems that typically score at band E or F
- Pre-1980s terraced and semi-detached homes -- often solid wall construction with limited insulation options
- Period cottages and stone-built properties -- frequently off-gas and difficult to retrofit
Properties with modern condensing boilers and good cavity wall and loft insulation may still reach band C under current and HEM metrics, but many will be marginal.
EPCGuide's analysis of 29.2 million EPC records shows 55.3 percent of all homes in England and Wales currently fall below band C. The private rented sector skews worse than the national average.
What Grants Are Available for Landlord Heating Upgrades?
Boiler Upgrade Scheme (BUS)
Landlords are eligible for BUS grants. The current grant is £7,500 toward an air source heat pump, regardless of income or means. Crucially, BUS grants do not count toward the £10,000 MEES cost cap. A landlord who spends £10,000 on a heat pump and qualifying fabric works, then receives a £7,500 BUS grant, has an effective out-of-pocket cost of £2,500. Apply through an MCS-certified heat pump installer: they handle the grant application on your behalf.
ECO4
ECO4 is tenant-eligibility-gated. Tenants must be on qualifying benefits (Universal Credit, Housing Benefit, Employment and Support Allowance and others) for the landlord to access funding. Where tenants qualify, ECO4 can fund up to £14,000 per property in energy efficiency improvements, also outside the MEES cost cap.
The scheme closes 31 December 2026. Landlords with benefit-claiming tenants should act before that date. See the full ECO4 grants guide for landlords for eligibility criteria and how to apply.
Warm Homes Plan
The government's successor to ECO4, expected from 2027. Details are still being set. Do not rely on it for properties that need to comply by April 2028.

Typical Costs for Landlord Heating Upgrades
Costs vary significantly by property type and existing system. These are indicative ranges for a standard 3-bedroom house:
| Upgrade | Typical Installed Cost | BUS Grant | Indicative Net Cost |
|---|---|---|---|
| Air source heat pump | £10,000-£14,000 | £7,500 | £2,500-£6,500 |
| Modern condensing gas boiler | £2,000-£4,000 | None | £2,000-£4,000 |
| Electric storage heater replacement (set) | £3,000-£6,000 | None | £3,000-£6,000 |
| Heat pump with additional fabric works | £15,000+ | £7,500 | £7,500+ |
Replacing a gas boiler with another gas boiler will not, on its own, solve a band D or E EPC under HEM. Combine any boiler work with insulation improvements for a better outcome.

What Should Landlords Do in 2026?
Check your current EPC. If your certificate is valid (under 10 years old) and shows band C or above, you are already compliant under current rules. Verify that the property state described still reflects reality.
Commission a new assessment if your EPC is old or does not reflect recent improvements. Assessments typically cost £60-£150. The new Home Energy Model launches in October 2026 and may re-score many properties, so a fresh assessment under current methodology locks in where you stand.
Start spending now: it counts from 1 October 2025. Qualifying improvements already contribute to your £10,000 MEES cap.
Apply for BUS before installing any heat pump. The scheme is live; the £7,500 grant substantially reduces the cost and does not reduce your cap headroom.
Act on ECO4 before 31 December 2026. If any of your tenants receive qualifying benefits, explore ECO4 funding before the scheme closes at year end.
Register a cost cap exemption if you genuinely cannot reach band C. After spending £10,000 in qualifying improvements, a property that still cannot reach band C is eligible for a cost cap exemption on the PRS Exemptions Register. Exemptions last 10 years.

Frequently Asked Questions
Do landlords have to provide central heating by law? Landlords must provide a fixed heating system capable of reaching 21°C in living rooms and 18°C in bedrooms at -1°C external temperature under the HHSRS. Central heating is the most common way to meet it, but heat pumps, electric underfloor heating or storage heaters can also qualify, provided they reach the temperature standard. Portable heaters do not count.
What is the minimum temperature a landlord must provide? Under the HHSRS, the standard is 21°C in the main living area and 18°C in bedrooms when outside temperature is -1°C. Failure to heat a property adequately can constitute a fitness-for-habitation breach and expose landlords to rent repayment orders covering up to 12 months' rent paid.
Will landlords have to replace gas boilers by 2030? Not by law. The 2030 requirement is to reach EPC band C, not to remove any specific heating system. However, gas boilers are capped at band D under the new Home Energy Model Heating System metric. Properties relying on gas heating with poor insulation will need additional measures to reach band C. Properties with modern condensing boilers and strong insulation may still hit C, but many will need extra work.
What EPC rating do landlords need by 2030? EPC band C, or its equivalent under the new Home Energy Model. New tenancies from 1 April 2028; all existing tenancies from 1 April 2030. The government confirmed these dates in its policy response published in January 2026.
What happens if a rental property has no fixed heating? Absent or inadequate heating is an HHSRS Category 1 hazard. The local council has a mandatory duty to act and cannot choose to ignore it. Tenants can also apply for rent repayment orders covering up to 12 months' rent. Portable heaters do not satisfy the legal requirement.
What is the £10,000 cost cap for MEES landlords? Landlords must spend up to £10,000 per property on qualifying energy improvements before registering a cost cap exemption. Spending counts from 1 October 2025. BUS grants and ECO4 funding sit outside this cap: a landlord who spends £10,000 and receives £7,500 via BUS has an effective net cost of £2,500 on the heat pump element.
How long does a landlord have to fix a broken boiler? There is no fixed statutory period, but Housing Ombudsman and case law guidance consistently expects landlords to respond within 24 hours and complete emergency heating repairs within 48-72 hours in cold weather. Heating is a Section 11 obligation and delays that leave tenants without heat in winter can constitute a fitness-for-habitation breach.
What exemptions exist if a property cannot reach EPC C? Confirmed exemptions include: cost cap (property cannot reach C after £10,000 spent), property value adjustment (sub-£100,000 homes), third-party consent where a freeholder, lender or tenant blocks the works, solid wall insulation, negative impacts on the property, and a 6-month grace period for new landlords. Exemptions are registered on the PRS Exemptions Register and last 10 years.
