If your home or business is supplied with Gas line services (Google`s blog), we will need to test and potentially replace the service pipe to your property. If we need to replace your service pipe, we will also need to disconnect your gas supply and we aim to have this restored on the same day. 1Gas deliver mains gas pipe connections, upgrades/downgrades & relocations throughout England, Scotland & Wales. We aim to deliver the best customer service possible combined with competitive prices.
