SunBoost
Competitive solar pricing with on-the-day professionalism — and named support staff who customers credit with solving real technical problems.
Individual support staff members like Noah, Jenny, and Naomi collect strong personal praise for resolving inverter, monitoring app, and battery commissioning issues when customers reach them. The concern that clears the threshold in this sample is communication reliability: roughly a fifth of the reviews we reviewed describe extended waits for callbacks, paperwork not submitted to energy providers, and warranty jobs taking months rather than days to resolve. That gap is worth planning for — before signing, get a named contact for your job and confirm the escalation path if that person becomes unreachable.

About SunBoost
SunBoost operates as a solar and battery installation company handling new residential systems, battery additions to existing solar setups, EV charger installs, and post-installation technical support. The team includes several named specialists whose roles emerge clearly across reviews: Noah handles ongoing customer service and technical follow-up for battery and inverter issues; Jenny resolves monitoring app problems and grid connection queries; Naomi troubleshoots system activation and commissioning challenges; Ethan deals with EV charger faults and inverter replacements; and Zack and Emilia handle inbound service calls and data logger resets. Pricing is flagged repeatedly as a genuine differentiator — multiple reviewers explicitly note SunBoost came in materially cheaper than competitors without cutting corners on the installation day itself, which tends to run punctually and professionally. Where the business divides opinion is in the territory between signed contract and completed installation, and between installation completion and warranty resolution — reviews in the 50-review sample split sharply between customers who got fast, attentive support and those who report weeks of silence, missed callbacks, and unresolved paperwork. SunBoost suits homeowners who want competitive pricing on a straightforward new solar or battery install and have a direct contact name to follow up with; it's a less natural fit for those managing a complex new build timeline or who need reliable proactive communication through a multi-month approval process.
Best for: homeowners seeking competitive pricing on a new residential solar or battery install, customers needing battery additions to an existing solar system, and those comfortable proactively managing communication with a named support contact post-installation.

What types of solar and battery systems does SunBoost install?+
Reviews mention a range of system sizes including 10kW, 13kW, and 20kW solar arrays, paired with batteries from brands including Growatt, Sigenergy, and FoxESS. Customers also mention EV charger installations completed alongside solar and battery packages. SunBoost appears to handle both new residential installations and upgrades to existing solar systems where a battery is being added. If you have a specific brand preference or a multi-storey or complex roof layout, confirm installer availability for your property type before signing.
How do customers describe SunBoost's pricing compared to competitors?+
Several reviewers in the sample explicitly note that SunBoost came in significantly cheaper than competing quotes — one described them as "by far the cheapest" when others charged "3 times more for less." That said, a small number of reviews mention unexpected costs arising after signing, including disposal fees and pre-wiring charges not clearly scoped upfront. Getting a fully itemised quote before committing — including disposal of old equipment and any site-specific costs — would reduce the chance of surprises.
Who should I expect to deal with if I have a problem after installation?+
The support team includes several named contacts who appear repeatedly across reviews. Noah handles ongoing technical queries for battery and inverter issues; Jenny fields monitoring app and grid connection problems; Naomi assists with system commissioning; and Ethan deals with inverter replacements and EV charger faults. When customers reach the right person, resolution is generally praised. The recurring caution in reviews is that reaching someone in the first place can require multiple calls — ask for a direct contact name at handover and confirm the after-hours process before your system goes live.
How long does the installation process typically take from signing to system switch-on?+
Reviews in the sample show a wide range. Some customers report a smooth process from quote to installation within a few weeks. Others describe waits of several months, particularly where grid approval, installer availability, or new build construction timelines are involved. Delays appear more common for complex properties, battery-plus-solar packages, and jobs in areas with limited contractor availability. Ask SunBoost for a milestone schedule in writing — including grid approval, installer booking, and energy provider paperwork — before you pay a deposit.
Does SunBoost service areas outside major cities?+
Reviews mention customers in remote and regional locations receiving service, with at least one reviewer noting a technician was dispatched promptly despite their remote address. That said, SunBoost uses a network of contracted installers rather than an entirely in-house team, so availability and response times in less populated areas may vary. Confirm your postcode is within active coverage and ask whether the assigned installer is local or travelling before agreeing to a timeline.
