Warm Homes Plan Explained: Grants, Heat Pumps, and Energy Savings

Mariel • February 2, 2026

Understanding the Warm Homes Plan

The Warm Homes Plan isn’t a single scheme — it’s an umbrella of initiatives aimed at helping homeowners improve energy efficiency and transition away from fossil fuel heating. Its main goals are to:


  1. Improve the energy performance of homes
  2. Reduce fuel costs
  3. Support low-carbon heating upgrades


By combining grants, finance options, and simplified rules, the plan makes it easier than ever to upgrade your home.

Financial Support and Grants

One of the key benefits of the Warm Homes Plan is financial assistance for homeowners:


  • Boiler Upgrade Scheme (BUS): Grants of up to £7,500 towards installing an air-source heat pump for most homeowners replacing a gas or oil boiler.
  • Affordable loans: Low- or zero-interest loans can cover heat pumps, insulation, solar panels, batteries, and heating controls, spreading costs over time.


These options make switching to low-carbon heating far more accessible.

Simpler Installation

Under the Warm Homes Plan, installing an air-source heat pump is now far more straightforward thanks to updated planning rules. Most standard installations no longer require planning permission, provided they meet permitted development conditions.


Recent changes mean larger outdoor units (up to 1.5 m³) are now allowed, the one-metre boundary restriction has been removed, and clearer guidance is in place around placement, noise limits, and system sizing. Detached homes may also install more than one unit where required.


These updates reduce delays, remove uncertainty, and make switching to low-carbon heating quicker and easier for homeowners.

A Clear Pathway to a Low-Carbon Home

Unlike older schemes aimed at specific groups, the Warm Homes Plan is now available to most homeowners and landlords, combining grants, energy efficiency improvements, and simpler installation rules to create a straightforward route to greener heating.

Whether you’re installing a new air source heat pump, upgrading an existing system, or looking to improve overall efficiency, focusing on home insulation ensures your system works at its best, delivering maximum comfort and energy savings.
Before installing a new air source heat pump, it’s important to know whether your home is properly insulated.
Darlington Heat Pumps can help check and assess your property to identify areas where heat is escaping and recommend improvements to maximise heat pump efficiency.

Contact Darlington Heat Pumps today to arrange an assessment and make sure your heat pump performs at its best.

When most people think of smart thermostats, they imagine them paired with a gas boiler — turning the heating up from your phone or letting the system learn your daily routine. But what if you’ve switched to a more efficient system, like an air source heat pump (ASHP)? Can the two work together? The short answer is yes — and when they do, you get the perfect mix of comfort, control, and energy savings.

Across the UK, rising energy prices have made many households look for better, long-term solutions to cut costs. At the same time, more people want to live sustainably and prepare their homes for the future. One of the smartest ways to achieve this is by combining air source heat pumps (ASHPs) with solar panels.

Home heating accounts for 38% of gas use in the UK, contributing to considerable CO2 emissions, with the average gas boiler emitting 2.2 tonnes of CO2 annually. An air source heat pump, powered by renewable electricity, offers a more sustainable alternative, which is why the government is promoting its adoption. The UK government aims to phase out gas boilers by 2035 as part of its plan to achieve net-zero emissions by 2050. To support this transition, grants are being offered to help households install air source heat pumps and other low-carbon heating solutions, encouraging homeowners to switch from their old gas and oil boilers to cleaner, greener options.
