Under current government rules, qualifying residential air conditioning installations can be charged at 0% VAT, helping homeowners save money on the upfront cost. This incentive is part of a wider push to encourage energy efficient home improvements but it won’t last forever.
Here’s everything you need to know, in simple terms.
What Is the 0% VAT Scheme for Air Conditioning?
The UK government introduced a temporary 0% VAT rate for the supply and installation of certain energy saving materials in residential properties. This includes many fixed air conditioning systems, especially those that also provide heating (often referred to as air to air heat pumps).
Before this change:
- Air conditioning installations were charged at 20% VAT
- Later reduced to 5% VAT under older schemes
Now, for eligible homeowners, VAT is completely removed from the installation cost.
Who Is Eligible for 0% VAT?
You can usually benefit from 0% VAT if:
- ✅ The property is residential (house, flat, apartment, bungalow, etc.)
- ✅ The system is supplied and installed by a VAT registered installer
- ✅ The air conditioning is a fixed installation
- ✅ The system is installed for domestic use, not business use
Eligible residential properties include:
- Owner occupied homes
- Rental properties
- Student accommodation
- Care homes
- Static caravans and houseboats
❌ Commercial properties (offices, shops, warehouses, hotels) do not qualify.
Does All Residential Air Conditioning Qualify?
Not quite. To qualify for 0% VAT, the system must meet certain criteria.
Qualifying Systems
- Wall-mounted or ceiling mounted split systems
- Multi split systems for multiple rooms
- Systems that provide both heating and cooling
- Permanently installed units with an outdoor condenser
These systems are classed as energy efficient technologies, especially when used for heating as an alternative to traditional electric or gas heating.
Non Qualifying Systems
- Portable air conditioners
- Plug in, standalone units
- DIY installations
- Equipment supplied without installation
If it’s not fixed to the building, it almost certainly won’t qualify.
How the 0% VAT Is Applied
This is important for homeowners to understand.
- If a VAT registered installer supplies and installs the system, the entire job (equipment + labour) can be charged at 0% VAT
- If you buy the air conditioning unit yourself, the unit will usually be charged at 20% VAT, even if installation is later zero-rated
- To maximise savings, it’s best to use a single installer for supply and installation
If air conditioning is part of a larger renovation or extension, the VAT treatment can become more complex. In many cases, having the air conditioning quoted and invoiced separately helps preserve the zero rating.
How Long Will the 0% VAT Last?
The 0% VAT rate is temporary.
- 🗓️ It currently applies until 31 March 2027
- After that, VAT is expected to revert to 5% unless the government extends the scheme
For homeowners considering air conditioning, acting sooner could mean significant savings.
How Much Can Homeowners Save?
The savings can be substantial.
For example:
- A £6,000 residential air conditioning installation
- 20% VAT would normally add £1,200
- With 0% VAT, that £1,200 stays in your pocket
For larger homes or multi-room systems, savings can easily reach several thousand pounds.
Why the Government Supports Air Conditioning
Modern residential air conditioning systems are very different from older models.
Many now:
- Use inverter technology
- Provide high efficiency heating
- Consume less energy than traditional electric heaters
- Reduce carbon emissions when replacing older systems
Because of this, air conditioning that provides heating is increasingly viewed as a low carbon heating solution, which is why it qualifies for VAT relief.
What Homeowners Should Do Next
Before installing air conditioning, homeowners should:
✔ Confirm the installer is VAT registered
✔ Ask for a clear, itemised quote showing 0% VAT
✔ Ensure the system is fixed and permanent
✔ Install before March 2027 to secure maximum savings
A reputable installer should be able to explain exactly why your installation qualifies and show this clearly on your invoice.
Final Thoughts
The 0% VAT on residential air conditioning installation is one of the most generous incentives currently available to UK homeowners. It reduces upfront costs, improves comfort, and supports more energy efficient homes.
If you’ve been considering air conditioning for your home, whether for cooling, heating, or both, now is one of the best times to do it.
