Water Efficiency Certificates & Rental Property Inspections

Licensed plumbers for Brisbane, Gold Coast, Logan, Ipswich, Tweed Heads and Sydney

Clear Evidence for Landlords and Property Managers

Need a water efficiency certificate for a rental property? Jetset Plumbing provides professional water efficiency inspections, plumbing upgrades and written reports for landlords, lessors, property managers, real estate agents and property owners.

Our licensed plumbers assess the relevant taps, showerheads and toilets against the requirements that apply in Queensland or New South Wales. You receive a clear result and, if something does not meet the required standard, practical advice about the repairs or upgrades needed.

Book an inspection before a new tenancy, after fixture upgrades or whenever the property's water efficiency evidence is incomplete.

Inspection, Advice and Repairs in One Service

We measure the flow rate of covered taps and showerheads, check toilet specifications and inspect for relevant leaks. Where practical, we can quote the work required to improve non-compliant fixtures, including approved flow-control products, efficient showerheads, tap or toilet repairs and toilet upgrades.

After a successful assessment, we provide written evidence of the inspection for your property records. This can help an owner or agent demonstrate water efficiency when reviewing whether water usage charges may be passed on to a tenant.

Water efficiency is only one part of the legal criteria for tenant water charging. Metering, tenancy agreement wording, billing evidence and time limits also apply. Because Queensland and NSW have different requirements, every property must be assessed against the rules for its location.

Rhys was absolutely amazing. Kind, helpful and courteous. Couldn't recommend anyone better. Even went to the shop for us and bought my niece and ice cream from the ice cream truck. Got everything sorted in the afternoon and was so lovely to chat to. Thankyou Rhys, you're such a saver. If I could give 10 stars I would.
I called Jetset today after having a prior excellent experience with them. My plumber today, Doug, was extremely professional and personable. He explained the issue and helped me work through the solutions to find the best scenario for my situation. I will continue to use Jetset for anything that comes up in the future and highly recommend the business and Doug!
Keith from jet set plumbing came out and was amazing, fixed our tap no issues, quick, professional. Thank you Keith for your help, we appreciate it. You are a jet set legend 🙌
Absolutely fantastic service! Keith from jet set came and fixed our leak, was brilliant from start to finish. He had it sorted quickly with no fuss, was incredibly professional, friendly and clearly knew his stuff. Keith was super friendly with our toddler who was really intrigued and interested in what was going on, he took sometime to show him his tools and talk about what he was doing.
Thank you so much, Keith, for your help — we really appreciate the great service.
Highly recommend!
Fantastic job by dug.
Reliable and honest

I would recommend this group - the first quote I was given for relining my pipes was $54k - yep !! Jetset did it for $20k

Same job done better and less than half the price

Definitely use Jetset
Fast and efficient service from Keith, would highly recommend
I called Jet Set Plumbing for my place in Varsity Lakes and Reece came. Reece was amazing. He went above and beyond. I called to just look at the downpipe but he inspected the sewage, the taps inside the house and provided a full comprehensive assessment - without me even asking. After everything he called much later to even check in to ensure everything was okay. I would recommend Jet Set Plumbing and Reece to everyone. Amazing customer service - the best.
After buying our first home, we had a wide variety of plumbing works needing to be done, and quickly. We saw the Jetset team and the overwhelmingly positive google reviews and went with the crowd. Boy are we glad we did.

This team has blown my socks off with how excellent their service and professionalism is. From start to finish, they provided clear and consise information about each job they completed, and did amazing work all the way along.

To top it off, we recieved a lovely little gift in the mail a month after all was completed, that we use every day.

Can't thank the team enough for their work and would encourage anyone to use Jetset in the future.
I’d like to thank Mitch of GC Jetset Plumbing for the excellent and meticulous workmanship, professionalism, prompt and on time service. Mitch showed willingness to share his knowledge and expertise for me to understand the job at hand and was up front and committed to his quote, start to finish. My weekend will be spent swanning past my bathroom to stare at my new toilet system and enjoy the peace of no running water , overflow or hissing 😂 Thank you Mitch and thank you Jetset Plumbing for your prompt service response.
I recently had Jetset Plumbing replace my hot water system, and I couldn't be happier with the service. Communication was excellent from start to finish, and Tom took the time to clearly (and kindly) explain the issues with my electrical system in a way that was easy to understand. The whole team was friendly, professional, and efficient. I highly recommend Jetset Plumbing, and a big thank you for the thoughtful surprise gift—it was such a lovely touch!
Jetset plumbing upgraded my 18 year old failing hot water system. Liam was assigned the job of replacing the system. He was very professional, polite and kept me informed of his progress. His workmanship was excellent and he left the site clean and tidy. Prior to completing the job he explained the key maintenance tasks that I needed to do every six months to ensure the system functioned optimally.
Water efficiency certificate and rental property plumbing inspection

What Is a Water Efficiency Certificate?

A water efficiency certificate is the common name for a licensed plumber's written report confirming the outcome of a rental property's water efficiency inspection. It records whether the fixtures covered by the relevant state requirements meet the required performance standards at the time of inspection.

The report gives owners and agents useful evidence for their records. It does not, by itself, make every water charge payable by a tenant. The property owner or manager must also satisfy the other tenancy-law requirements that apply in Queensland or NSW.

What Our Water Efficiency Inspection Covers

  • Flow-rate testing of the taps and showerheads covered by the relevant state rules
  • Checking toilet type, flush performance or WELS information as applicable
  • Checking for visible leaking taps and toilets where required
  • Identifying fixtures that need adjustment, repair or replacement
  • Providing a written inspection result for the owner or managing agent

If a fixture fails, our plumbers can explain the most practical next step. Related work may include leaking tap repairs, toilet plumbing, shower repairs or investigation of an unexpectedly high water bill.

Queensland Water Efficiency Requirements

For rental properties in Brisbane, Gold Coast, Logan and Ipswich, the Queensland Residential Tenancies Authority states that a lessor may pass on full water consumption charges when all minimum criteria are met: the premises are individually metered (or water is delivered by vehicle), the premises are water efficient, and the tenancy agreement states that the tenant must pay for water consumption.

Queensland fixture Minimum water efficiency standard
Internal cold-water taps and single mixer taps over hand basins, kitchen sinks and laundry troughs Maximum flow rate of 9 litres per minute
Showerheads Maximum flow rate of 9 litres per minute
Toilets Dual flush not exceeding 6.5 litres full flush and 3.5 litres half flush, with a maximum average flush volume of 4 litres

Queensland's tap requirement excludes bathtub taps, outdoor garden taps and taps supplying appliances such as washing machines and dishwashers. Current details are available from the Queensland RTA water charging fact sheet.

What Queensland tenants can and cannot be charged

When the minimum criteria are satisfied, the RTA says a tenant may be charged the State Bulk Water Charge and water usage charges. Sewerage usage charges and fixed access charges, including water and sewerage access charges, cannot be passed on as water consumption charges.

The lessor must also follow the current rules for supplying evidence of the water charge and requesting payment. Owners and agents should check the RTA's current guidance rather than relying on a plumbing report as tenancy-law advice.

NSW Water Efficiency Requirements

For rental properties in Tweed Heads and Sydney, NSW rules apply. A landlord can ask a tenant to pay water usage charges only when the property is separately metered (or water is delivered by vehicle), meets the prescribed water efficiency measures, the charge is no more than the landlord was billed, and the tenant receives the required bill or evidence.

NSW fixture or condition Water efficiency measure
Cold-water and single mixer taps for internal kitchen sinks and bathroom hand basins Maximum flow rate of 9 litres per minute
Showerheads Maximum flow rate of 9 litres per minute
All toilets Dual flush with a minimum 3-star WELS rating
Leaks No leaking taps or toilets anywhere on the property at the start of the tenancy and when water efficiency measures are installed, repaired or upgraded

The NSW tap flow-rate measure excludes taps for bathtubs, laundry sinks, washing machines, dishwashers and outdoor use. The minimum 3-star WELS dual-flush toilet requirement has applied for this purpose since 23 March 2025. See the current NSW Government water efficiency guidance.

Water Efficiency Certificate FAQs

What is a water efficiency certificate?

A water efficiency certificate or report is written evidence from a licensed plumber recording whether the relevant taps, showerheads and toilets meet the water efficiency requirements for the property's state. It can help a landlord or agent demonstrate compliance, but the other legal conditions for charging a tenant for water must also be met.

Do landlords need a water efficiency certificate?

A plumbing certificate is a practical way to document an inspection when fixture ratings or performance are not otherwise clear. Queensland RTA and NSW Government guidance both recognise plumbing reports or written statements as evidence, alongside items such as receipts, packaging and product information.

What does a water efficiency inspection include?

The plumber checks the fixtures covered by the applicable state rules, measures relevant tap and shower flow rates, inspects toilet specifications and looks for issues such as leaking taps or toilets. The written report records the result and identifies upgrades or repairs where required.

What is the maximum tap and shower flow rate?

For the fixtures covered by the Queensland and NSW rental water efficiency rules, the maximum flow rate is generally 9 litres per minute. The types of taps included and excluded differ between the states, so the property must be assessed against the correct jurisdiction.

Are the water efficiency rules the same in Queensland and NSW?

No. Both states include flow-rate requirements, but the covered taps, toilet standards, leak requirements and water-charging procedures differ. NSW requires all toilets to be dual flush with a minimum 3-star WELS rating for this purpose from 23 March 2025.

Can you repair fixtures that fail the inspection?

Yes. Depending on the fixture and its condition, Jetset Plumbing can quote suitable work such as repairing leaks, installing approved flow-control products, replacing showerheads or taps, and upgrading toilets. Compliance is confirmed only after the relevant work and final checks are complete.

How long does a water efficiency certificate last?

The tenancy guidance does not set a universal expiry period for a plumber's report. Owners should retain the report and supporting records, and arrange another assessment if fixtures are replaced, altered, damaged or leaking, or if the applicable requirements change.

Where do you provide water efficiency inspections?

Jetset Plumbing provides water efficiency inspections for rental properties across Brisbane, Gold Coast, Logan, Ipswich, Tweed Heads and Sydney, subject to appointment availability.

This page provides general information only and is not legal advice. Residential tenancy and water-charging rules can change. Owners, agents and tenants should confirm their obligations with the Queensland RTA, NSW Fair Trading or an appropriately qualified adviser.
