Watch: 5 Best Water Heater Services in Singapore (2026)

How we score

Every number on this page is computed from public Google data on the date shown, not from opinion or payment. Rating is the company’s live Google star average. Review volume is how many customers have rated them, ranked against other Singapore water heater and plumbing companies. Confidence weighs the rating by that volume, so a 5.0 across nearly 2,000 reviews carries more weight than the same score on a handful. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much does water heater installation cost in Singapore? (2026)

Water heater pricing depends on whether it’s a like-for-like replacement or a fuller job involving new piping, wiring or mounting. Reviewers on this page mention jobs running from a few hundred dollars for a straightforward swap to higher figures when wiring and piping upgrades are included.

Serving all of Singapore

The companies above cover the island, from Kallang and Ang Mo Kio to Bukit Batok and central Singapore, with island-wide coverage advertised by several. Searching for water heater services near me? Every listing below shows a live phone number so you can reach the closest option.

What to ask before you hire a water heater service

Is the company PUB licensed for water heater and plumbing work?
Is the quote flat-rate, and does it change if the piping or wiring needs work too?
Will you handle the PUB Certificate of Satisfactory Completion after installation?
How soon can you come out for an emergency, and is there an after-hours surcharge?
What warranty covers the new water heater and the installation labor?

Frequently asked questions

How did you choose these water heater services?

We started from water heater installation and repair companies in Singapore with a public Google presence, then ranked by rating, review volume, consistency and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Which of these companies offers genuine 24/7 emergency service?

BS Integrated Engineering specifically advertises 24/7 response with no after-hours surcharge. Several others also handle urgent callouts, so ask directly about current response times when you call.

How much does water heater installation cost in Singapore?

Costs vary too widely by scope, whether piping or wiring upgrades are needed, to quote a general range responsibly. Ask each company for a written quote before work begins.

The bottom line

Mr Plumber Singapore is the safe default on scale and broad coverage, while Homeone Water Heater is the specialist pick for a full, thorough replacement. Whichever you call, confirm PUB licensing and get the quote in writing before work starts.
