A really big thank you to Ron and his team, he has vast amounts of knowledge and got my system back up and running, also good to get on with. I was absolutely lost as to know what to do, no help from installer and somehow came across Ron and am I glad I did. I would definitely definitely recommend him to anyone who has faults with there solar system, any make I would say. Thanks again Ron a pleasure meeting you.
quick service - sorted in 30 mins. well worth saving yourself hours of reading Facebook forums! thanks
Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them
Brilliant. He fitted a new dongle and set the system up properly. Even better, he explained why the storage batteries don't work in a power cut - not correctly wired up - expensive to fix, but a simple turn of the master switch will give emergency power. He is the third technician to look at this issue and the only one to resolve it. Friendly and appoachable, comes when he says he will and reasonable charges. What's not to like!
Ron very quickly diagnosed what was wrong with my GivEnergy system. Unfortunately the kit has died after only 3.5 years of use-which is quite sad and timing couldn’t be worse with GivEnergy gone bust. Ron gave me advise on how to handle this with my installer. I’m hoping they’ll be forthcoming, but if they aren’t i now have a good idea how to deal with that. Thanks a lot Ron!
Had a fault on a GivEnergy AC coupled 3kW home battery and was getting no joy from multiple companies I contacted, as well as the original installer. Contacted Solar Tech Support and they sorted it really quickly, now working perfectly again, can’t recommend them highly enough, professional and very responsive!
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 £295.
Fault diagnosis →Old unit out, new one in. Configured, commissioned, and tested. All brands. From £995.
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 — £125 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 on brands other than GivEnergy, 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. Dead inverter guide →
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, a Timed Charge window that is not enabled, or incorrect tariff settings. We fix this remotely in most cases. Battery not charging overnight →
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 →
Snug Energy was headquartered in Doncaster. Mark Group installed thousands of systems here through government schemes. Both are gone. If your installer has closed, we can still help: monitoring transfer on brands other than GivEnergy, documentation rebuild, warranty claims, fault diagnosis, and ongoing support.

Many of the GivEnergy systems across Doncaster were installed by Snug Energy before their closure. These are modern, capable systems — they just need independent ongoing support. We handle every GivEnergy model and fault type, from battery diagnostics to firmware updates to full inverter replacement. GivEnergy Ltd entered administration on 9 April 2026, so its manufacturer warranty is no longer being honoured. With Snug Energy gone as well, any remaining cover may come from an insurance-backed guarantee, a Section 75 credit card claim, or the MCS Consumer Code. We check which of those applies, and we supply and install replacement GivEnergy hardware at fixed prices.

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.
