Book a documentation reviewInstaller gone bust hubMy solar panels stopped producing unexpectedly, contacted Ron who assisted me initially remotely and then visited to correctly diagnose that the problem was on the roof. Within a month the solar panels are now up and working, kept me up to date with when scaffolding arriving and the lads who checked the solar panels, a very professional team, organisation and service
Wow... a firmware update to my inverter sent the whole system into meltdown – the battery discharged, and the house seemed to be drawing power, and the solar, who knows where that was going? Aghhh... A short email exchange with Roland and Solar Tech Support sorted the problem... the firmware had reversed a setting (from when it was installed), and the CT clamp needed to be reversed. As soon as I had done that, the world returned to normal. Thanks, Roland; there is no way I would have come to that conclusion. Would I recommend them? You bet! Worth the fee? You bet, again!
Fantastic support. We have a Givenergy system where one of our batteries was not working. Ronald successfully helped us get it back up. His perseverance was amazing….and it shows what REAL customer service means. Can’t thank you enough Ron!
Great advice from Ronald at Solar Tech Support, got my inverter back on line and stable.
Just had my whole givenergy system go down. Battery and inverter. Ron sorted me out today 3 hours to get it all sorted. Clear instructions and successful. Could not ask for better. Now that givenergy has gone bust i was concerned as to where to go for help. I have found it and can recommend them to all you givenergy users out there. Off for a cup of coffee now😄
I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration. So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.
A properly completed installation should provide six categories of documentation. Most are needed at different points — for SEG applications, insurance, warranty claims, or property sale.
Issued by the Microgeneration Certification Scheme. Proves the system was installed by an accredited installer to UK standards.
Needed for: SEG applications, home insurance, property sale. Status: Recoverable free from mcscertified.com for most systems.
Proof that the system was registered with your Distribution Network Operator.
Needed for: SEG applications, grid compliance, property sale. Status: Recoverable from DNO or can be filed retrospectively. Full DNO paperwork guide →
Signed by the qualified electrician at the time of installation. Documents the electrical safety and compliance of the wiring and connections.
Needed for: Home insurance, mortgage applications, property sale. Status: Original cannot be re-issued — but an EICR (Electrical Installation Condition Report) from a new electrician is accepted as a substitute by most parties.
Separate warranty documents from each equipment manufacturer covering their component. These are issued by the manufacturer — not the installer — and usually remain valid regardless of installer closure. Two exceptions: GivEnergy Ltd entered administration on 9 April 2026 and no further hardware warranties will be honoured (GivEnergy warranty guide), and Fox ESS claims go through a Local Installer, a role we can take on (Fox ESS warranty guide).
Needed for: Warranty claims, property sale. Status: Recoverable directly from manufacturers using serial numbers. Warranty claim guide →
The installer's final report documenting system performance at handover — panel layout, equipment details, initial readings. Many small installers never issued this.
Needed for: Future diagnostics and repairs. Status: Usually unrecoverable if the installer has gone. Can be partially recreated by an independent engineer.
Proof of purchase, installation date, and system cost.
Needed for: Manufacturer warranty claims, proof of ownership. Status: If lost, the MCS certificate provides installation date and system details which substitutes for most purposes.
Priority order: If you can only recover some documents, focus on: (1) MCS certificate, (2) DNO registration or G98/G99 filing, (3) EICR from a new electrician. These three cover the vast majority of what insurers, SEG suppliers, and conveyancers need.
Start here before spending anything. Several of the most important documents are publicly available or can be requested directly from organisations that already hold them.
The MCS public register holds details of every certified solar installation in the UK. This is your first and most important stop.
The certificate shows: installer name, installation date, system size, inverter and battery make and model, and panel details. This single document covers most of what insurers, SEG suppliers, and conveyancers ask for.
Free. Most systems from 2012 onwards are listed. Pre-2012 installs and non-certified installers may not appear.
Manufacturer warranties are held by the manufacturer — not the installer. They remain valid regardless of what happened to the installer and can be confirmed or re-issued directly.
Free. Response time: 3–7 working days.
Your DNO may have the original G98 notification or G99 approval on file even if you were never given a copy. It costs nothing to ask.
Free or small fee (£10–20). Response time: 5–10 working days. See our full DNO paperwork guide if registration is missing entirely.
Technical documentation for your inverter, battery, and panels is freely available from manufacturer websites. These help with troubleshooting and give future engineers everything they need to understand your system.
Visit the manufacturer website, navigate to downloads or product support, enter your model number, and download the relevant datasheet and installation manual. Keep digital copies.
Free. Always available for current models; older discontinued models may require contacting support directly.
Work through these steps in order. The first three cost nothing. Steps four and five require professional involvement but are well-established routes.
Before searching externally, collect all existing paperwork — you may have more than you think. Check:
Scan or photograph everything and store digitally. Make a list of what you have and what is missing before proceeding.
Visit mcscertified.com and search by your postcode. If found, download the PDF immediately. This single document can satisfy most third-party requirements on its own.
If your address doesn't appear: try the previous owner's name if you've recently bought the property, or try a partial postcode search. If still not found, contact MCS directly at info@mcscertified.com with your address and approximate installation year.
With your serial numbers in hand (from labels on the equipment), contact your inverter and battery manufacturers to request warranty documentation. Simultaneously, contact your DNO (via energynetworks.org) to ask if registration is on file.
Both of these are free and can run in parallel. Keep written records of all correspondence. If DNO registration is missing entirely, see our DNO paperwork guide for how to file retrospectively.
If the original Electrical Installation Certificate is missing, an EICR from a qualified electrician is the accepted substitute. The original EIC was issued at installation and cannot be re-issued, but an EICR documents the current safety of the installation and is accepted by most insurers, conveyancers, and lenders.
Cost: £150–£300. Time: 1–2 weeks from booking.
Once you've recovered as much as possible, compile everything into a single folder with a summary sheet. This becomes your master record for all future needs.
Your summary should include: installation date, original installer name, inverter make/model/serial, battery make/model/serial, panel brand and count, system size (kW), list of all documents recovered with dates and sources, and notes on any documents created retrospectively.
This folder is what you hand to conveyancers when selling, share with electricians doing future work, or provide to warranty teams when making claims.
Typical total cost: £0 if MCS and DNO records are found · £150–£300 if EICR is needed · £200–£500 if both an EICR and a retrospective DNO filing are needed — the G98 filing alone is typically £50–£200 (see our DNO paperwork guide). Timeline: 4–8 weeks for a complete recovery including EICR and G98 filing.
We can work through the documentation recovery process with you, provide professional reports, and refer you to qualified electricians where physical inspection is needed.
We'll review what you have, identify what's missing, and give you a prioritised action plan — saving you time working out what matters most.
A written report from us confirms the current operating state of your system. Useful for insurers, future electricians, warranty teams, and conveyancers.
We can help you regain access to your manufacturer's monitoring portal and export historical performance data — useful for baseline records and diagnosing issues.
If a component has failed and you need to make a manufacturer warranty claim, we can produce the diagnostic report manufacturers require and handle correspondence on your behalf. Warranty claim guide →
Where physical site work is needed — EICR, G98/G99 filing, or fault investigation — we can refer you to MCS-registered electricians we work with.
If you're selling, we can review your documentation pack and confirm readiness for conveyancing, or advise on what needs to be resolved before listing.
We'll review what you have, identify what's missing, and give you a clear plan — whether that's downloading your MCS certificate, coordinating an EICR, or preparing a documentation pack for a property sale.
