Air conditioning running costs
Modern air conditioning systems are designed to be energy efficient, but many homeowners and businesses still wonder how much they cost to run. On this page we explain typical electricity usage and the factors that affect air conditioning running costs.
Running cost factors
Example running costs
Running costs depend on the type of air conditioning system, the room size, how long the unit is used and the electricity tariff. These examples are guide figures to help explain typical air conditioning electricity costs in the UK.
A smaller domestic air conditioning unit cooling a bedroom or study under normal day-to-day use.
A larger room or open-plan space generally needs more output, so electricity use can be higher than a single bedroom unit.
Typical running cost for a home office unit used through a normal working day in warmer weather.
A small commercial unit serving an office, salon or retail space will usually cost more to run because of longer usage hours and larger cooling demand.
What affects running cost
There is no single fixed running cost for air conditioning because electricity use depends on how the system is used and how hard it has to work. Factors such as room size, target temperature and system efficiency all make a difference.
Larger rooms, open-plan spaces and rooms with lots of glazing often need more cooling output, which can increase electricity use.
The lower you set the target temperature in cooling mode, the harder the system may need to work and the more electricity it can use.
Modern, efficient air conditioning systems are usually cheaper to run than older or less efficient units providing the same level of cooling.
A system used occasionally for a short period will cost less to run than one operating for long hours every day in a home or business.

Air Conditioning Electricity Cost Questions
Many people assume air conditioning is expensive to run, but modern systems are designed to be highly energy efficient. Below are answers to some of the most common questions about air conditioning running costs and electricity usage.
Running costs depend on the size of the system, the room being cooled and how long the air conditioner runs each day. A small bedroom air conditioning unit may cost around 20p to 45p per hour to run, while larger systems used in living rooms or commercial spaces will typically cost more.
Modern air conditioning systems are designed to be very energy efficient. Many units use inverter technology which adjusts power usage depending on the cooling demand, meaning they do not always run at full power. This helps reduce electricity consumption compared to older systems.
In many situations it can be more efficient to maintain a comfortable temperature rather than letting a room become very hot and then cooling it rapidly. Running the system at a steady setting can reduce the amount of work required from the air conditioner.
Yes. Modern air conditioning systems are typically far more efficient than older models. New systems use improved compressors, inverter technology and energy efficient components which help reduce electricity usage and overall running costs.
