No current ban on gas boiler replacement (June 2026)

Gas boilers remain lawful in existing rental properties. Landlords can replace broken boilers with new condensing models. The proposed EPC C MEES floor is not yet enacted in legislation but is the direction of travel.

Current position

As at June 2026, landlords can replace a broken gas boiler with a new A-rated condensing model. There is no ban on gas boilers in existing rental properties. The policy pressure comes from MEES (Minimum Energy Efficiency Standards) rather than a direct boiler ban.

EPC C and MEES: the real deadline

Current MEES floor: EPC E for all rental properties. Letting an F or G rated property is unlawful and attracts civil penalties of up to £2,000 (breach under 3 months) or £4,000 (3 months or more), capped at £5,000 per property
Proposed MEES upgrade: EPC C by 2028 (new tenancies) and 2030 (all tenancies), with a £15,000 cost cap, not yet enacted in legislation as at June 2026
A modern gas condensing boiler combined with loft insulation and cavity wall insulation often achieves EPC C on standard 1970s£1990s stock without a heat pump
Heat pumps achieve EPC B or A in well-insulated properties and qualify for the £7,500 Boiler Upgrade Scheme grant

What landlords should do now

Commission a current EPC if more than 3 years old, SAP methodology has been updated
Replace broken boilers with modern A-rated condensing gas boilers, lawful and EPC-positive
Model the EPC C pathway using the Potential EPC section of your current EPC report
Budget for insulation works (loft/cavity wall) as the most cost-effective EPC improvement
Explore heat pump viability if radiators are large, insulation is good, or the property is being fully refurbished
Monitor MEES legislation, the proposed EPC C floor has not yet been enacted

Frequently asked questions

Is it illegal to have a gas boiler in a rental property in 2026?+

No. As at June 2026, gas boilers remain completely lawful in existing rental properties. Landlords can replace a broken boiler with a new gas condensing boiler without restriction. The proposed MEES EPC C requirement (not yet enacted in legislation) may require heating system upgrades by 2028 to 2030, but this does not ban gas boilers; it requires EPC C compliance, which can often be achieved with a modern condensing boiler plus insulation.

What grants are available to landlords for heating upgrades?+

The Boiler Upgrade Scheme (BUS) provides £7,500 grants for air source heat pumps in England, available to landlords. The Great British Insulation Scheme and ECO4 provide subsidised insulation for lower EPC band properties. Applications for heat pump grants are made through MCS-certified installers.

Do I have to install a heat pump in my rental property?+

No. There is no current legal requirement for landlords to install heat pumps in existing rental properties. Heat pumps are one option for improving EPC ratings, and the Boiler Upgrade Scheme provides a £7,500 grant. However, landlords can also achieve EPC improvements through insulation, boiler upgrades, and other measures. The practical decision depends on the property's construction, insulation, radiator sizing, and current EPC rating.

What happens if my rental property does not meet EPC C when required?+

Under the current MEES regulations, letting an F or G rated property without a registered exemption is unlawful and attracts a civil penalty of up to £2,000 for a breach of under 3 months or £4,000 for a breach of 3 months or more, capped at £5,000 in total per property. If the proposed EPC C floor is enacted (currently proposed for new tenancies from 2028, all tenancies from 2030 with a £15,000 cost cap), letting a D or E rated property without a valid exemption would similarly attract civil penalties. Exemptions are expected where the cost cap has been reached without achieving C, for conservation areas or listed buildings where improvements are restricted, and for newly marketed properties within a limited grace period.
