The installation of CNG kits in cars, including the cylinder, is debated as either a supply of goods or services for GST purposes. If considered a supply of goods, the GST registration limit is £40 lakh, meaning no registration is needed below this threshold. If classified as a service, the limit is £20 lakh.

It will be supply of goods because you are charging major amount of cylinder. So GST registration limit will be 40 lacs in case of goods. So up to 40 lacs you no need to take GST registration.
