Installer gone bust · Documentation

Recovering solar documentation after your installer went bust

When an installer ceases trading, homeowners are often left with no paperwork — or paperwork they can't find. Most documentation can be recovered from public sources at low or no cost. What can't be recovered can usually be recreated by a qualified professional.
  • MCS certificate is free to download from mcscertified.com
  • EICR substitutes for a missing Electrical Installation Certificate
  • Most documentation gaps can be resolved in 4–8 weeks
After this guide you'll be able to:

Identify exactly which documents you're missing, recover as many as possible yourself for free, and arrange professional substitutes for the rest.

I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.

When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.

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

Dennis Brown · May 2026 Trustpilot

Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)

Tony Deacon · May 2026 Trustpilot

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

Phill · May 2026 Trustpilot

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

michael fairhurst · May 2026 Trustpilot

Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.

After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.

Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.

Hugh Speirs · Apr 2026 Trustpilot

Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.

Christopher · Apr 2026 Trustpilot

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 (their Trustpilot reviews don't lie!). 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.

This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.

Andy Thomas · Apr 2026 Trustpilot

I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

Checklist

What documentation should a solar installation come with?

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.

MCS Certificate

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.

DNO Notification or Approval (G98 / G99)

Proof that the system was registered with your Distribution Network Operator before connecting to the grid.

Needed for: SEG applications, grid compliance, property sale. Status: Recoverable from DNO or can be filed retrospectively. Full DNO paperwork guide →

Electrical Installation Certificate (EIC)

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.

Manufacturer Warranties (inverter, battery, panels)

Separate warranty documents from each equipment manufacturer covering their component. These are issued by the manufacturer — not the installer — and remain valid regardless of installer closure.

Needed for: Warranty claims, property sale. Status: Recoverable directly from manufacturers using serial numbers. Warranty claim guide →

i
Commissioning Report / System Summary

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.

i
Invoice and Receipt

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.

Free recovery

What you can recover yourself — free or low cost

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.

MCS certificate — mcscertified.com

The MCS public register holds details of every certified solar installation in the UK. This is your first and most important stop.

How to find yours:
Visit mcscertified.com → click "Search the MCS register" → enter your postcode → find your address and installation year → download the PDF certificate.

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 warranty documentation

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.

Find the serial numbers on your inverter (label on side or rear) and battery (label on the unit)
Visit the manufacturer's website (GivEnergy, Sunsynk, SolarEdge, Growatt, etc.) and locate their support or warranty section
Email or call with your serial number to request warranty documentation and confirm coverage end date

Free. Response time: 3–7 working days.

DNO registration records

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.

Identify your DNO (check your electricity bill or use energynetworks.org)
Contact them with your address and approximate installation date
Ask if a G98 notification or G99 approval exists for your address and request a copy

Free or small fee (£10–20). Response time: 5–10 working days. See our full DNO paperwork guide if registration is missing entirely.

Equipment datasheets and manuals

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.

Process

Step-by-step: how to recover or recreate missing documentation

Work through these steps in order. The first three cost nothing. Steps four and five require professional involvement but are well-established routes.

1
Gather everything you already have

Before searching externally, collect all existing paperwork — you may have more than you think. Check:

Invoices or receipts from the installer (filing cabinet, email inbox)
Warranty cards or booklets left in equipment boxes in the loft or cupboard
Printed or laminated certificates (sometimes left by the inverter)
Emails from the installer — check spam and deleted folders
Any pack or folder left by the installation engineer on the day

Scan or photograph everything and store digitally. Make a list of what you have and what is missing before proceeding.

2
Search for your MCS certificate

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.

3
Recover DNO registration and manufacturer warranties

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.

4
Arrange an Electrical Installation Condition Report (EICR)

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.

Search for a qualified electrician (NAPIT, NICEIC, or ELECSA registered)
Request an EICR specifically for your solar installation
They will inspect the system and issue a PDF report within 1–2 weeks

Cost: £150–£300. Time: 1–2 weeks from booking.

5
Compile a system summary document

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 DNO registration needs to be filed retrospectively. Timeline: 4–8 weeks for a complete recovery including EICR and G98 filing.

FAQ

Frequently asked questions

Most systems installed from 2012 onwards are listed on mcscertified.com, but not all. Very old systems (pre-2012) or those installed by non-certified installers may not appear. If your address isn't found, try searching under any previous owner's name, try a partial postcode, or contact MCS directly with your system details. Without an MCS certificate you can still proceed with other documentation — DNO records and an EICR together cover most requirements.
The original EIC was issued at the time of installation and cannot be re-issued — it was a point-in-time document signed by the electrician who did the work. However, a qualified electrician can produce an Electrical Installation Condition Report (EICR) which assesses the current state of the installation and is accepted as a substitute by most insurers, conveyancers, and lenders. Cost is typically £150–£300 and it can usually be arranged within 1–2 weeks.
Conveyancers typically ask for: MCS certificate, DNO registration (G98/G99 notification or approval), Electrical Installation Certificate (or EICR if original is missing), manufacturer warranties, and any active SEG contract. If you're missing documents, provide what you have and explain the situation in writing. An MCS certificate plus an EICR covers the most important requirements and most sales proceed without delay when these are provided alongside a clear explanation.
Sole traders are not registered at Companies House, so there's no official dissolution record. Try any contact details from your original paperwork — even if they've stopped trading, many will still respond to email. Check Google, local directories, and Checkatrade. However, in most cases you can bypass the original installer entirely: file retrospective G98/G99 registration and get an EICR from a new electrician. This resolves the compliance issues without needing to trace anyone.
Search for the company at find.company-information.service.gov.uk to find the administrator or liquidator's contact details. These are listed in the company's filing history. You can contact the administrator and request copies of installation documentation related to your property — many will cooperate if you explain the situation clearly. Keep notes of all correspondence. If records are not available from the administrator, use the MCS, DNO, and EICR routes to rebuild your documentation independently.
