 Trustindex verifies that the original source of the review is Google. I can't recommend Tiny Build Electrics enough! When staring my van build journey, I had no knowledge of electrical systems and how they work. With the help of Tiny Build Electrics and their knowledge and patience, I understood very quickly what to look out for and how to follow regulations. These guys aren't just a "one system fits all" type of company. Every system is designed to fit your needs and requirements. Apart from their vast knowledge which they are very happy to share, I was greatly impressed by the customer orientated human factor behind every interaction. Nothing is too much, no question is dismissed. Tiny Build Electric has managed to build a like minded community where helping each other solve problems and understanding your systems is at the forefront. If you're looking for a solid company who knows what they're doing with great customer service and a like-minded community, TBE is it! Thanks Tom and Charlie :)

 Trustindex verifies that the original source of the review is Google. I started with having a consultation with Tom after I wasn’t fully confident in another company’s specifications for our system and from that chat with Tom I decided this is who I want my system from it was so simple Tom took all the information on what we needed and explained all the different options and what he would recommend and how the system would work and the wealth of post purchases support available so we ordered everything and I installed it with the simple to follow schematics and install manual then took the van to Charlie to be inspected and tested for the peace of mind a service I couldn’t find anywhere else. There after sale support is excellent with the WhatsApp group and a community of like minded people no problem is to big and to and Charlie are always there to help. Would 100% recommend and will be using them for all my future projects

 Trustindex verifies that the original source of the review is Google. A very cleverly set up business for the keen but novice van builder. My electrical system set-up was designed and purchased 2 years ago, and I have installed it in phases. With the Whatsapp group I feel fully supported - users further on in the process will dip in to questions, and if it's a major question, Tom and Charlie will respond.

 Trustindex verifies that the original source of the review is Google. I started off with just a single consultation but ended up getting a full system from these guys. Their support has been continuous and ongoing and they’ve built an active community to support all the small questions that pop up. I would recommend them without reservation.
