How Much Does Air Conditioning Cost?

A common question we are often asked is: how much does air conditioning cost?

In the UK, as summers become increasingly warmer, more homeowners are considering the installation of air conditioning systems to maintain comfort in their homes.

In this short guide, we’ll explore the various costs involved in installing air conditioning systems – which can be as affordable as £1,450 – and what factors influence these costs.

Initial Installation Costs

Cost Factors

The cost of installing an air conditioning system varies based on several factors:

  • Type of System: Split systems, multi-split systems, and portable units vary in price.
  • Size of the Property: Smaller homes or specific rooms require less powerful units, reducing costs.
  • Installation Complexity: The ease of installation can impact labour costs. For example, more complex installations in homes without existing ductwork will be more expensive.

Cost for a Small System

For a basic system, suitable for a single room or a small house, the cost of supplying and installing the unit starts from as little as £1,450.

Air conditioning installations are 0% VAT rated which means there is no increase in cost for VAT.

This guide price would typically include a basic split system unit and standard installation fees.

Running Costs

Energy Efficiency

Running costs depend on the system’s energy efficiency rating and the amount you pay per kWh for your home electricity. More efficient systems have higher upfront costs, but lower running costs.

Average Running Costs

For a small, energy-efficient air conditioning unit, the average running cost can range from £30 to £60 per month when used moderately during warmer months.

Servicing & Maintenance Costs

Importance of Regular Servicing

Regular servicing is crucial to ensure the efficiency and longevity of your air conditioning system.

We can carry out an annual service for you – see our Air Conditioning Servicing page for more details.

Typical Servicing Costs

An annual service, which includes cleaning filters and manufacturer checks, can cost between £75 and £150 for a small system. Neglecting servicing can lead to higher running costs and reduced system lifespan.

Additional Cost Considerations

Installation Surveys

Some companies offer free installation surveys, but others may charge a fee. This survey assesses the best system for your home and what installation would involve.

Infinity Energy Services doesn’t charge an air conditioning survey fee.

Extended Warranties

Consider the cost of extended warranties for peace of mind and protection against future faults or breakdowns. We can advise whether this might be a good idea or not for specific makes and models.

Long-term Savings

Reduced Energy Bills

An energy-efficient air conditioning system can lead to savings on your energy bills, as it can be more efficient than traditional cooling methods, like electric fans or older air conditioning systems.

Increased Property Value

Installing air conditioning can increase your property value, making it an attractive feature for potential buyers or renters. As climate change plays havoc with the weather and temperatures, the versatility of an air conditioner will give added value to your home.


Installing air conditioning in your home is an investment that goes beyond just the initial installation cost.

While a small system can be installed for as little as £1,450, it’s important to consider the running and servicing costs, as well as the potential long-term savings and benefits.

By understanding these factors, homeowners can make an informed decision about whether air conditioning is the right choice for their home and budget.
