  Thunder Sparks recently completed our solar and battery installation in Billericay using an Aiko and Sigenergy system, and we’re really pleased with the result. From the start, Jody and the team stood out in a very reassuring way. Jody took the time to explain everything clearly, answered our questions, and was never pushy. The installation was smooth, professional, and completed to a high standard. Highly recommend Thunder Sparks for anyone considering solar.

  Hi Alex, as we've not done any work for you or ever heard of you, I doubt we've given you bad service. Kindest Regards

  We recently had solar panels installed at our newly built home in Billericay by ThunderSparks, and the whole experience was excellent from the very start. Jody and the ThunderSparks team were incredibly knowledgeable and took the time to explain how the solar PV system and battery storage would work for our house, costs and returns. They were also the only ones who were willing to fit the system to a seam roof and do different roof orientations. It seems theres two type of installers. The ones who can (Thundersparks) and the ones who only want to do roof hooks and brackets. The installation itself was clean, tidy and very professional. The team arrived on time, completed the solar installation and left everything clear - when building a home you start to notice builders who leave stuff behind! They also handled the MCS paperwork, commissioning and system setup, which made the whole process very easy for us. (and left a nice little gadget so I never lose the documents) Since the install we’ve been generating a lot of our own electricity and even exporting some back to the grid. It’s great seeing the system producing power on sunny days. Mildly addictive. If you’re looking for reliable solar installers in Billericay or anywhere in Essex, I would highly recommend ThunderSparks. Professional, knowledgeable and clearly very experienced with solar panel installations.

  Joe is an absolute professional when it comes to electrics! He saved the day when we thought our whole house may have needed rewiring but instead he reassured us it was a lose wire and managed to fix the issue very swiftly. Highly recommend!

  Thank you! - Gotta say, glad I managed to lift it up the stairs. Pretty heavy lump wasn't it. - Hope Solax honour the warranty properly for you.
