💰 Ways to save
- Mind the floor-height buildup in a retrofit — traditional screed adds around 100mm and can foul doors and skirtings, whereas thin electric mats add only a few millimetres. That alone often decides electric versus hydronic in an existing home.
- Even a DIY mat kit legally needs a licensed electrician for the power, conduit, thermostat and load certification — budget for that, don't assume it's a weekend job.
How we estimate this
Underfloor heating is priced per square metre installed, and the type sets the rate. Electric ranges from $60–$100/m² for slab cable up to $100–$160 for an under-tile mat and $120–$200 for in-screed cable. Hydronic pipework is $45–$100/m² in-slab or $70–$150 retrofit — but that excludes the heat source, which adds a gas boiler at $3,000–$7,000 or a heat pump at $6,000–$15,000 on top.

What a underfloor heating costs in Melbourne
Melbourne's cold, wet winters are what make underfloor heating a real proposition here rather than a novelty: it ranges from an electric mat warming a bathroom floor to a whole-home hydronic system running warm water through pipes in a slab, a serious heating solution the climate genuinely justifies. Hydronic in particular suits Melbourne, and designing it into a new slab is far cheaper than retrofitting under an existing floor, where the finish has to come up.
The city's deep pool of plumbers, electricians and heating specialists keeps the work competitive, and the choice between electric mats for a room and hydronic for the whole house is the main thing that sets the scale of the job. Reactive-clay slabs need to be sound before a hydronic system is cast in. A licensed electrician or plumber is required depending on the system. For a Melbourne home, the cold winters make underfloor heating one of the more worthwhile comfort investments on this list.

Frequently asked questions
How much does underfloor heating cost?
In 2026, electric runs $60–$200/m² depending on type, and a bathroom mat is about $600–$1,500. Hydronic pipework is $45–$150/m² but the heat source adds thousands — a 200m² hydronic whole-home system with its heat pump reaches $30,000–$50,000.
Electric or hydronic?
Electric suits single rooms like bathrooms and is cheap to install. Hydronic only pays off above about 80m² and is far cheaper to run at scale, so it suits whole-home heating — but mainly in cold-climate states like Victoria, Tasmania and the ACT.
Can I run it on demand?
No, not in-slab or in-screed systems — they take 10–24 hours to warm up, so they have to run on a schedule. That's ideal for steady winter heating but useless for a quick warm-up, where a thin electric mat responds faster.
