Important Pricing Information

Our listed prices apply to standard, like-for-like replacements of existing hot water systems, assuming the new unit is similar in type and easily accessible.

If your setup requires additional work-such as new pipework or valve upgrades-extra charges may apply. These costs generally range between $80 and $550. Any variations will be clearly explained by our technician before work begins, so you know exactly what to expect.

Please note:

Quoted pricing is based on compliant installations. If your system requires upgrades to meet current plumbing or gas regulations, this may incur additional costs. Again, our team will always discuss these with you upfront.
