How Much to Charge for Air Con Installation
There's no fixed price for an air con install — the figures below are indicative and vary by region, unit and access. The number that pays your business comes from your own materials, labour and margin, not someone else's headline rate.
'What should I charge to install air conditioning?' is a fair question with no single answer. What a job earns depends on the unit and refrigerant, the pipe run and access, the electrical work, your overheads and the going rate where you work — none of which a national average captures.
This guide gives some indicative 2026 UK ranges so you can sense-check your pricing, then shows how to build a price from your own numbers. Treat every figure here as a rough guide, not a rate card: price from your costs, not from a benchmark.
Key takeaways
- The ranges below are indicative and regional — not fixed prices to quote from.
- A single split install commonly lands around £1,500–£3,000 supplied and fitted, depending heavily on the job.
- A routine service commonly sits around £70–£120, but access and scope move it.
- Price from your own materials, labour, overheads and target margin — not a national average.
- Difficult access, long pipe runs and extra electrical work all push the real figure up.
Indicative 2026 UK ranges
The table gives rough 2026 UK figures for common air con jobs. They're a sanity check — a way to see whether your quote is broadly in the right area — and nothing more. A supplied-and-fitted single split commonly falls somewhere around £1,500–£3,000, and a routine service around £70–£120, but both ranges are wide because the jobs behind them vary enormously.
Read every figure as indicative and regional. The same unit costs more to fit in a tricky top-floor flat with a long pipe run than in a simple ground-floor room, and prices in one part of the country don't transfer to another.
| Job type | Indicative range |
|---|---|
| Single split, supplied & fitted | ~£1,500–£3,000 |
| Additional / multi-split (per extra indoor unit) | ~£800–£1,500 |
| Routine service | ~£70–£120 |
| Diagnostic / callout | ~£80–£150 |
Why a fixed price doesn't exist
Two 'single split installs' can be very different jobs. Access is the big variable — a straightforward run on an accessible wall versus scaffolding, a long concealed pipe route or an awkward outdoor-unit position changes the labour completely. Add the unit and refrigerant chosen, the electrical work required, and the length and complexity of the pipework, and the real cost spreads across a wide band.
That's why a headline 'average' is a poor guide to your quote. The figure that matters is what the specific job in front of you costs you to do, plus the margin your business needs.
Price from your own costs
Build the price from the bottom up. Start with materials — the unit, pipework, insulation, cabling, brackets and consumables — at your buying price. Add your labour, costed at a day rate that already covers your overheads, for the realistic time the job takes including the pressure test, vacuum and commissioning. Then apply the margin your business needs to be sustainable.
Do it this way and your price reflects your actual costs and the value of the work, not a number lifted from a forum. It also means that when access is awful or the pipe run is long, the extra time lands in the price instead of quietly eating your margin.
Cover the whole job, including commissioning
Price for the pressure test, evacuation, charging and commissioning, not just the fixing time. These steps take real hours and skipping them in your pricing is how a 'competitive' quote turns into an unprofitable job.
Turning costs into a quote
Once you have materials, labour and margin, a job-pricing calculator turns them into a consistent number, and a day-rate calculator makes sure the rate your labour is costed at genuinely covers your overheads. That keeps your quotes profitable and comparable from one job to the next.
Present the price clearly and, once the work's done, invoice promptly — a branded invoice sent the same day gets you paid faster and finishes the job off properly.
Quote and invoice from one place
Building the price from your costs and then invoicing from the same job in TradePlanr keeps the numbers consistent from quote to payment — and gets the invoice out while the work's still fresh.
Frequently asked questions
How much does it cost to install air conditioning in the UK?
As an indicative 2026 guide, a single split system supplied and fitted commonly lands around £1,500–£3,000, but the figure varies widely with the unit, access, pipe run and region. It's a sanity check, not a fixed price — quote from your own costs.
How much should I charge for an air con service?
A routine service commonly sits around £70–£120 as an indicative figure, though access and scope move it. Base your own price on the time and materials the service takes plus your margin, rather than a benchmark.
Why do air con installation quotes vary so much?
Because the jobs vary. Access, the unit and refrigerant chosen, the length and complexity of the pipe run, and the electrical work all change the labour and materials, so two 'single split installs' can cost very different amounts. That's why you price from the specific job, not an average.
