How much does a single split air conditioning unit cost to install in Essex? We break down the real numbers — supply, installation, running costs, and what affects the price.
One of the first questions we get from Essex homeowners considering air conditioning is: how much does it cost? The honest answer is that it varies — but we can give you a very clear picture of what to expect.
Supply Costs: The Unit Itself
Single split AC units range widely in price depending on the brand, capacity, and energy efficiency rating. Here are typical supply prices for quality units:
Entry level (budget brands, A+ rated): 2.5kW unit £350–£500 / 3.5kW unit £450–£650 Mid-range (Samsung, LG, Panasonic): 2.5kW unit £550–£800 / 3.5kW unit £700–£950 Premium (Daikin, Mitsubishi Electric, Fujitsu): 2.5kW unit £800–£1,200 / 3.5kW unit £950–£1,400 / 5.0kW unit £1,200–£1,800
We strongly recommend investing in a mid-range or premium unit. The energy savings justify the higher upfront cost, and these brands have significantly better reliability and longer lifespans (15–20 years vs 8–12 for budget units).
Installation Costs
Installation costs depend on the complexity of the job — primarily how difficult it is to route the refrigerant pipes and electrical supply. Typical installation prices:
Total Installed Costs
For a mid-range single split system, you're typically looking at:
Running Costs
This is where single split AC scores extremely well. A 3.5kW system running at full capacity consumes approximately 1.0–1.2kW of electricity per hour — thanks to heat pump technology, it delivers 3.5kW of heating/cooling for 1.0–1.2kW of electrical input.
At the current average UK electricity rate of approximately 24p per kWh, running a 3.5kW unit for 8 hours per day costs approximately £1.90–£2.30 per day — comparable to or cheaper than a gas boiler for the same room.
What Affects the Price?
- ✓Long refrigerant pipe runs (over 5 metres).
- ✓Multiple floor levels to negotiate.
- ✓The need for a new dedicated electrical circuit.
- ✓Restricted access for the outdoor unit.
- ✓Conservation area or listed building requirements.
