💰 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 Gold Coast
The Gold Coast's humid subtropical climate means underfloor heating is uncommon and purely a comfort touch, almost always a small electric mat under tiles in a bathroom renovation, where a warm floor is a nice-to-have on a cool winter morning rather than anything the climate demands. A whole-home hydronic system makes little sense in a city whose real climate challenge is cooling, humidity and salt, not heating, so it is very rarely specified.
Where it is fitted, the cost turns on the small heated area of a bathroom and the construction, with an electric mat far cheaper designed into a renovation than retrofitted under existing tiles. A high share of coastal housing is apartments, where bathroom renovations carry body-corporate considerations. Rates track the south-east Queensland market a little above the Brisbane baseline, and a licensed electrician is required. For a Gold Coast home, underfloor heating is a modest bathroom luxury rather than a heating strategy.

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.
