Ron was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
I work for a Solar Company and had a customer with a GivEnergy system that we are not versed in. Ron took the time to explain the issues my customer was having and between us managed to rectify the issues. 10 Stars ... Thanks again STS
A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.
Contacted Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone
My GivEnergy solar and battery system is failing intermittently, GivEnergy is in administration and so is my installer, so it was a relief to get Ron’s expert advice.
I've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues
Doncaster has a high density of residential solar installations — many from the 2012–2015 FiT era on 1950s–1970s housing stock. The borough was also heavily served by Snug Energy, which was based locally at Kirk Sandall before going into liquidation. The result is a lot of solar systems approaching the age where inverters fail, and a lot of homeowners who've just lost their installer.
Snug Energy was headquartered at Kirk Sandall Industrial Estate and served customers right across South and West Yorkshire. Their liquidation in December 2025 left many Doncaster homeowners without anyone to call for warranty claims, monitoring access, or fault support. The systems themselves are usually fine — modern hardware, relatively recent installs. They just need someone to manage them.
Much of Doncaster's solar sits on post-war and 1960s–1970s housing — semis and terraces in Bentley, Balby, Intake, and Wheatley. These homes typically carry older 2–4kW FiT-era arrays with string inverters that are now 10–13 years old. The roof orientations are generally good for solar, but the inverters are reaching the end of their working life.
Newer installations and battery retrofits in Doncaster predominantly use GivEnergy hardware. Snug Energy was a common installer of GivEnergy systems locally, so many of these GivEnergy customers now need independent support. We handle every GivEnergy fault — battery not charging, inverter errors, monitoring offline, tariff configuration, and firmware updates.
We have no affiliation with any installer, manufacturer, or competitor. We work for you. Our diagnostics are impartial — if your system is fine, we'll tell you. If it needs work, we'll explain exactly what and why before quoting. Every cost is confirmed in writing before we start.
Doncaster has a high concentration of FiT-era systems installed between 2011 and 2014, many now past their initial inverter warranty. We remote-diagnose every job before arriving — checking fault codes, generation history, and monitoring data. No call-out charges. Written quotes before any work.
Fault diagnosis and on-site repair — inverter failures, generation drops, grid faults, battery problems. From £245.
Fault diagnosis →Old unit out, new one in. Configured, commissioned, and tested. All brands. £795.
Inverter replacement →Many Doncaster battery systems are ready for EPS but were never wired up. We install the dedicated backup circuit and configure the battery's emergency mode.
EPS installation →Annual health check — generation benchmarking, inverter diagnostics, DC isolator and wiring inspection, firmware review. Written report with recommendations. From £195.
Annual maintenance →Bought a Doncaster property with solar? We visit, map the full system, set up monitoring, check whether FiT or SEG applies, and give you a written walkthrough report. From £295.
On-site walk-through →Quick remote diagnosis — monitoring data review, fault log analysis, firmware check. Written report usually same-day. Ideal as a first step before booking on-site. Free — £75 only if we fix it remotely.
Remote diagnostic →The faults we see most on Doncaster systems. A mix of ageing hardware problems and orphaned-installer recovery work.
The most common enquiry we get from Doncaster right now. Snug Energy customers who've lost access to monitoring, can't get warranty claims processed, or have a fault with no one to call. The systems themselves are usually modern and working — they just need someone to take over support. We handle the full recovery: monitoring transfer, documentation, warranty verification, and ongoing maintenance. Snug Energy guide →
Doncaster's older FiT-era systems from 2012–2015 are reaching the point where inverters fail. The housing stock in areas like Bentley, Balby, and Intake is predominantly 1950s–1970s builds with compact 2–4kW arrays. The panels will keep going for decades, but string inverters typically last 10–15 years. When yours stops, we swap it — same-visit where possible. Inverter replacement →
Many of the newer GivEnergy systems in Doncaster — particularly those installed by Snug Energy — are set up for time-of-use tariffs like Octopus Go. When the battery stops charging overnight, the cause is almost always configuration: charge schedule reset by a firmware update, eco mode disabled, or incorrect tariff settings. We fix this remotely in most cases. GivEnergy support →
A less obvious but increasingly common issue on older Doncaster installs. DC isolators — the switches between panels and inverter — can degrade over time, causing intermittent generation drops, arcing, or complete shutdown. Symptoms include the inverter cutting out during peak generation or a burning smell near the isolator. This is a safety issue that requires an on-site visit. Fault diagnosis →

Doncaster's 1950s–1970s housing stock means a lot of solar homes are on the market at any given time — and Snug Energy's recent closure means even more properties are changing hands with unresolved system issues. If you've bought a house with panels and the previous owner can't tell you who installed them, whether there's a warranty, or why the monitoring app shows nothing — we sort all of that out on a single visit.
Describe the fault — what you're seeing, the brand if you know it, when it started. If your installer has gone bust, tell us who they were. We'll come back with a clear plan and price, usually same day.
