💰 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 Newcastle
Newcastle's mild coastal climate means underfloor heating is bought for comfort rather than need, most often as an electric mat under tiles in a bathroom renovation where warm floors are a prized touch, rather than as a whole-home system. The city's installers charge below Sydney's while drawing on the same Hunter and Central Coast trade pool, so a comparable job is better value here than in the bigger city.
The cost turns on the heated area and the construction: designing an electric mat into a renovation is far cheaper than retrofitting under existing tiles, so it is usually planned as part of a bathroom reno in the city's older cottages and brick homes. A licensed electrician is required to connect the system under NSW rules. For a Newcastle home, underfloor heating is an affordable bathroom comfort upgrade, with the below-Sydney labour making it better value than in the bigger city.

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.
