Our boiler servicing procedure

In most cases, there is a procedure to follow contained in the boiler manufacturers instruction book. Where this book is available our engineers will follow the instructions for servicing the boiler. If the book has been lost then we will use the default service procedure set out in the "Essential Gas Safety" book issued by Corgi.
