An independent post-installation snag inspection documents all defects and incomplete work — from missing labels and damaged tiles to loose connections and poor cosmetic finish. You get a formal report and written evidence if you need to escalate.
Book a snag inspection — from £295What's includedAfter recently changing my fuse board the ct clamp broke, this meant my inverter was not communicating properly with my GivEnergy system. After several people letting me down, finally got put in touch with Ron. He came out within 24hours & resolved the fault within an hour, no fuse just got on with it. Work was tidy & arrived when he said he would. Ron followed up a few days later to confirm all was still good, great service from all involved.
Very speedy response. Handled by a real human who took my system through a logical process with the desired outcome within minutes of them accessing my inverter settings. Ron passed me on to Ash, they are both ex-Givenergy people who clearly know their stuff and can give the reassurance of proper technical support now that the Givenergy support desk has closed. A worthwhile investment in ensuring my expensive kit is kept fully functioning.
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
Ron made more sense in 20 mins than our installer has done over the last 12 months There is a jungle out there and you need someone like Ron to give a comprehensive overview and solution
Solar Tech Support answered my initial enquiry swiftly. They provided remote support to establish what the issue was, and through their experience and network, managed to get my clients system back online. Once the system was online, STS managed to diagnose the main issue to get the ac coupled inverter and battery back online, a battery repair was required. A site visit was organise and within a few days, the system was tested and back up and running. This has saved my client, and probably myself huge costs and inconvenience now the system is back online and working correctly. Would highly recommend.
When my GivEnergy battery started playing up it became basically useless and several companies I called said they couldn’t help. Solar Tech Support really knew their stuff, communicated very well and resolved the problem quickly. Without them I’d have had to buy a replacement battery.
Here are the issues we see most often. Some are cosmetic, some are worth fixing, and some are legitimate defects.
Broken or lifted roof tiles, gaps around roof flashings, missing sealant, or visible cracks. This is not cosmetic — water can ingress around roof penetrations, causing damage inside the loft and property. Roof defects must be fixed before final handover.
DC cables hanging loose, not clipped to the roof properly, not routed through cable trays or conduit, or visibly messy. Poor cable routing is a safety and aesthetics issue. Cables should be neatly fixed and protected. This is a legitimate snagging item.
DC isolator, AC isolator, battery isolator (if installed), or inverter mode not labelled. Warning signs missing. Labels are required by UK building regulations and safety standards. Missing labels are a compliance issue and should be added before final sign-off.
Minor scuffing on frame rails, paint marks from drilling, small marks on roof or walls, or aesthetic blemishes that do not affect function. These are cosmetic and lower priority, but worth noting if the installation was supposed to be 'like new' on completion.
Equipment installed in damp areas, exposed to direct sun, placed where it blocks access, or mounted at an awkward height. Poor placement can affect performance and longevity. The installer should relocate equipment to a more suitable location if it is genuinely problematic.
Missing MCS installation certificate, no electrical safety certificate (NICEIC/NAPIT), no Building Regulations completion, no user manuals, or incomplete commissioning notes. Documentation is essential for warranty, export payments, and future sales. The installer must provide all paperwork before you sign off.
A quick reference to help you distinguish between acceptable variations and genuine defects.
Follow this process to document, report, and resolve snagging items with your installer.
Walk around your entire installation — on the roof, around the inverter, at the battery (if installed), and check all visible wiring and connections. Take clear photos of any issues you notice. Record the date, time, and location of each problem. If possible, use a spreadsheet or simple document to organize your findings with photo references.
Be thorough but fair — do not nitpick minor cosmetic marks, but do flag anything that affects safety, function, or looks incomplete.
Compile your observations into a clear, written list organized by area (roof, wiring, equipment, documentation). For each item, describe what you found, where it is, why you think it is an issue, and how urgent it is (cosmetic, needs fixing, urgent). Do not rely on a phone call — written documentation is essential if you need to escalate.
Example format: "Roof: Two cracked tiles on east side of panel array — water ingress risk. Photos attached. Priority: Urgent."
Email your snagging list to your installer with all photos attached or linked. Use email so you have a clear date stamp and audit trail. Explain that you are requesting these items be completed as part of the post-installation service. Be polite and professional — you want them to come back and fix things, not get defensive.
Subject line example: "Post-installation snagging items — [Your address] — requesting completion"
Allow your installer 14 days to acknowledge your list and schedule a return visit. Most reputable installers will come back within 7–14 days to complete snagging work — it is a standard part of the installation contract. They may ask for clarification or dispute some items, but they should engage with you.
If you do not hear back within 14 days, send a follow-up email. If they still do not respond, or if they refuse to complete the work, proceed to the next step.
If your installer is unresponsive or refuses to fix snagging items, book an independent post-installation snag inspection. An independent inspector will assess all issues, document them formally with photos and measurements, and provide a written report. This report becomes evidence if you need to escalate the complaint.
With a formal report, you can pursue a complaint through the installer's trade body (MCS, NAPIT, RECC), withhold or reduce final payment, or seek legal advice if the issues are safety-critical.
A post-installation snag inspection documents all defects, incomplete work, and compliance issues with clear photos and written evidence. You get a formal report you can use to pressure your installer into action, or to support a complaint if they refuse to help.
