Book an SEG review — from £75What's includedI 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
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)
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
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
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.
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.
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.
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!

Why your SEG application might be stuck
There are five main reasons SEG registrations stall or fail. Most can be resolved once you identify the cause.
The SEG supplier verifies your MCS certificate against the MCS public database. If the certificate number you provided does not match, or if your installer never completed the MCS registration, the application will be rejected. This is the single most common cause of failed applications. Check the MCS database yourself first.
The address on your MCS certificate must match the address on your SEG application. If you moved into a property with solar already installed, the certificate may still be registered to the previous owner's address format. Even small differences (flat numbers, postcodes, abbreviations) can cause a mismatch. Contact MCS or your installer to correct it.
The SEG requires a smart meter (SMETS2 or enrolled SMETS1) or a dedicated export meter that records half-hourly data. If you have a traditional meter, your application will sit in a holding queue until one is installed. Contact your import supplier to book a free smart meter installation — this is separate from your SEG supplier.
Some energy suppliers have significant processing backlogs for SEG applications, especially during peak installation periods (spring and summer). If your application has all the right documents but has been pending for over 6 weeks, the delay is likely on the supplier's side. You can chase them, escalate to complaints, or withdraw and apply with a different supplier.
Missing fields, incorrect MPAN (meter point reference number), or wrong system capacity figures can all cause rejections. Some suppliers do not notify you of issues — the application simply stalls. Contact your supplier and ask them to review your application and confirm which fields, if any, need correcting.
If your installer ceased trading before completing the MCS registration, you will not have a valid certificate. Without it, no SEG supplier can accept your application. You will need a new MCS-accredited installer to inspect the system and submit a retrospective certificate. See our documentation recovery guide for the full process.
Step-by-step: fix your SEG registration
Work through these checks in order. Most people find the cause at step 1 or 2.
Contact your chosen SEG supplier and ask: "Do you have a record of my SEG application?" Get a reference number and the date it was received. Some suppliers' online forms do not send confirmation emails, so you may have started the process without completing it.
If they have no record, you need to submit a new application. Make sure you have your MCS certificate number, MPAN, and meter serial number ready before you start.
Go to the MCS certificate database and search for your installation. You can search by postcode, installer name, or certificate number. Confirm that the certificate exists, the address matches your property, and the capacity listed is correct.
If the certificate does not appear, your installer may not have completed the registration. Contact your installer first. If your installer has gone bust, see our documentation recovery guide for alternative routes.
You need either a SMETS2 smart meter, an enrolled SMETS1 smart meter, or a dedicated export meter. If you have a traditional meter (the type with a spinning disc or simple digital display), you need a smart meter installed before your SEG application can progress.
Smart meter installations are free from your electricity import supplier. Book one now if you do not already have one — the SEG application will remain in the queue until the meter is confirmed. Once the smart meter is installed, notify your SEG supplier so they can update your application.
If your application was rejected, the supplier must tell you why. Call them and ask for the exact reason — not a generic "application unsuccessful" message. The most common reasons are: MCS certificate not found, address mismatch, no eligible meter, or MPAN does not match their records.
Once you know the specific reason, fix it and resubmit. For MCS issues, you may need to contact MCS directly on 0207 090 1082 or your original installer. For meter issues, contact your import supplier. For MPAN issues, check your electricity bill for the correct 13-digit reference.
If your application has been pending for more than 6 weeks and the supplier cannot give you a clear timeline, escalate to their complaints team in writing (email is best — it creates a paper trail). If they cannot resolve it within 8 weeks of your original complaint, you can take the case to the Energy Ombudsman.
Alternatively, you can withdraw your application and apply with a different SEG supplier. There is no requirement to use the same company that supplies your electricity. Compare current rates on our Smart Export Guarantee guide and choose a supplier with better processing times.
SEG registration requirements checklist
Before you apply (or reapply), confirm you have everything on this list. Missing any one of these will cause your application to fail or stall.
What if you do not have an MCS certificate?
Without an MCS certificate, you cannot register for the SEG. Here are the main scenarios and what to do about each.
Contact your installer and ask them to complete the MCS registration. They are required to do this as part of an MCS-accredited installation. If they refuse or are unresponsive, you can report them to their MCS certification body (listed on the MCS website). If your installer is still trading but not cooperating, this is a breach of their MCS accreditation conditions.
This is one of the most common reasons for missing MCS certificates. You will need a new MCS-accredited installer to inspect your system and submit a retrospective certificate. This typically costs £200–£500 and involves confirming the installation meets current standards. See our detailed documentation recovery guide for the full process and what to expect.
The MCS certificate should have been included in the property sale documents (it is part of the recommended handover pack). If you did not receive it, check the MCS database by postcode — the certificate may exist but was not handed over. If it does not exist, the previous owner's installer may not have registered it, and you will need to follow the retrospective certification route. See our check export payments guide for property-specific steps.
If your system was installed by a non-MCS installer (for example, a general electrician or a DIY installation), it will not have an MCS certificate and cannot be registered for SEG under normal circumstances. You would need an MCS-accredited installer to inspect the entire system, potentially bring it up to standard, and submit a retrospective certificate. This can be expensive and is not always feasible.
