Grants for Flats: Finally, Funding for Leaseholders

For years, UK leaseholders living in flats have been stuck between a rock and a hard place. They are often locked into long contracts and paying high service charges, everyday bills, and major repair costs, while having very little control over how their own homes are upgraded or improved.

As UK summers continue to get warmer, more flat owners are now asking the same question about how to keep their homes cool.

Thankfully, this has begun to change. Leaseholders can now benefit from a growing range of grants and support programmes aimed at building safety, energy efficiency, and whole-building retrofit, many of which directly affect whether modern cooling systems can be installed.

So what are the key schemes leaseholders should know about in 2026, especially if they are thinking about AC units or air-to-air heat pumps?

What Are The Top Schemes Leaseholders Should Know About?

For those currently in a lease agreement, there are several grants that you should know about that will help you with:

• Structural work
• Energy efficiency and retrofit support
• And financial assistance funds

Let’s start with structural work grants.

Jargon Buster: Air-to-Air Heat Pump
A system that extracts heat from the outside air and transfers it indoors to provide heating, or reverses the process to provide cooling by moving heat from the inside to the outside.

Structural Work Grants To Know About

When we talk about building safety grants, we mean funding to address serious issues affecting the structure and safety of a block of flats. These are not cosmetic upgrades.

For leaseholders interested in installing air conditioning or improving ventilation, this work is more important than many people realise. Assessing the air conditioning installation cost or improving ventilation often depends on external wall repairs, fire-safety upgrades, and façade remediation, which are often required before freeholders will approve external condenser units, new wall penetrations for ventilation, or communal ducting systems.

Without these safety upgrades, managing agents may legally refuse permission for any external equipment, even if the system itself is energy efficient and professionally installed.

What Is the Cladding Safety Scheme?

Originally called the Building Safety Fund, this programme was created to address dangerous cladding and other serious external wall defects. It is now known as the Cladding Safety Scheme and funds fire-safety and façade remediation on residential buildings over 11 metres.

From a cooling perspective, this scheme can be the difference between a building where external AC units are permanently banned and one where safe, compliant installations become possible. Once external walls are upgraded to modern fire standards, managing agents can legally approve equipment that was previously prohibited.

Importantly, the funding is paid at the building level and does not come through service charges, meaning leaseholders are protected from massive remediation bills that would otherwise block all other upgrades. To access this funding, the responsible entity, such as the freeholder, managing agent, or registered landlord, must apply on behalf of the building. Leaseholders can and should encourage them to do so if the building is eligible and has not yet applied.

An Engineer’s View

Many leaseholders don’t realise that the condition of their building’s external walls is the most common technical hurdle we face during surveys. Securing cladding or safety funding doesn’t just lower your service charges; it literally paves the way for us to install the external condenser units and wall penetrations required for modern cooling.

Energy Efficiency And Retrofit Support

Leaseholders may not always apply directly, but there are energy-focused grants that, if the building qualifies or if the freeholder or landlord takes them up, can reduce the cost of energy upgrades. What matters most is that leaseholders have practical pathways to upgrade cooling systems legally and affordably.

Why Retrofit Schemes Matter For AC In Flats

Modern cooling in the UK is increasingly shifting toward air-to-air heat pumps. These systems provide cooling in summer, efficient heating in winter, typically use less electricity than traditional portable AC units, and can improve EPC ratings when installed as part of wider efficiency upgrades. Understanding the air-to-air heat pump costs involved is an important first step for any budgeting leaseholder.

They are already widely used across Europe and are becoming more common in UK flats, particularly within retrofit programmes. However, they often require external units, building-wide electrical capacity checks, and planning or freeholder approval. This is why building-level retrofit funding is so important.

When electrical infrastructure, ventilation routes, and building fabric are already being upgraded, approvals for cooling systems are far easier to obtain and installation costs are often lower.

Warm Homes Funding and Local Authority Support

Warm Homes funding is mainly aimed at insulation and heating efficiency, but in practice, it often unlocks wider building upgrades. These can include electrical infrastructure improvements, ventilation upgrades, and fabric changes that reduce overheating. All of these make modern AC or air-to-air heat pump systems easier to approve and more effective once installed.

In social housing blocks, these upgrades are usually arranged by the housing provider. For privately owned flats, councils may still support shared upgrades where overheating and poor ventilation are contributing to health risks. Many such projects are backed by insights from the Energy Saving Trust to ensure long-term efficiency.

In addition, schemes such as the ECO4 scheme and Warm Homes: Local Grant provide council-administered support designed to help lower-income households in privately owned or privately rented homes access energy-efficiency measures such as insulation, low-carbon heating, and smart controls. Availability depends on local funding rounds, and eligibility is usually based on income, benefits, or property energy performance.

Great British Insulation Scheme And What Comes Next

The Great British Insulation Scheme (GBIS) was a government-backed programme that helped households improve energy efficiency through relatively simple upgrades like loft and wall insulation. While the scheme has now closed, it played an important role in improving parts of the housing stock that had long been overlooked, including many blocks of flats.

More importantly, newer retrofit programmes increasingly focus on whole-building energy performance, ventilation standards, and overheating mitigation, rather than only insulation. While EPC ratings still concentrate heavily on winter efficiency, policy and retrofit standards are now paying more attention to summertime comfort and indoor air quality.

For leaseholders, this means future funding is more likely to support improved ventilation systems, shading and fabric upgrades, and heat-pump-based heating and cooling systems as part of broader building improvements.

Air-to-Air Heat Pumps And Cooling Grants

Most government grants are still labelled as heating support, but air-to-air heat pumps fall into a grey area that is increasingly favourable to leaseholders. In buildings where individual systems are allowed, these units can sometimes qualify under low-carbon retrofit schemes when installed as part of energy-efficiency upgrades, ventilation improvements, or overheating mitigation projects.

For flats with communal heating systems, cooling is usually only considered when the entire building is being upgraded, which is why building-level funding remains so critical. If a building is already undergoing retrofit for safety and energy efficiency, that is often the moment when cooling infrastructure becomes easiest to approve and cheapest to implement.

Finance Options For In-Flat AC Installations

Even when building works are funded, leaseholders are often responsible for their own internal AC or heat-pump units, any electrical upgrades inside the flat, and installation costs. These costs are rarely covered by government grants. This is where finance becomes the practical bridge between approval and affordability.

Instead of paying several thousand pounds upfront for a split AC system or an air-to-air heat pump installation, leaseholders can spread the cost over monthly payments. This makes it far easier to upgrade without waiting years for savings to build up. The result is cooler homes during heatwaves, improved EPC ratings, and lower long-term running costs, without taking a financial hit all at once.

Even when approval is granted, many leaseholders delay upgrades because of the upfront cost. That is where finance can make the difference between putting things off and actually getting the work done.

Practical Next Steps for Leaseholders Thinking About AC

Now that you’re ready as a leaseholder to get AC installed in your home, what steps should you take? If cooling is becoming a serious concern in your flat, the smartest approach is usually to:

• Ask whether your building has applied for safety or retrofit funding
• Check whether façade or fire-safety restrictions currently block AC installations
• Confirm whether your lease allows external units or wall penetrations
• Speak to managing agents during any funded upgrade windows
• Explore finance options for in-flat systems once approval is possible

For those navigating complex lease terms, the Leasehold Advisory Service offers valuable guidance on your rights regarding property alterations.

Cooling upgrades in flats rarely happen in isolation. They usually become viable when wider building improvements are already underway. If those improvements have already been completed, it may be the right time to review your installation and financing options.
