Company info

We are Synergy Southern Ltd, formerly Roger Treagust Ltd & Grate Fyres, the same people and experience, just a new name to streamline our marketing message. 

Our company is based in Emsworth, Hampshire, and we've been trading as a limited company for 17 years and previously as a partnership, bringing our trading experience to more than 31 years.

Our company operates within the plumbing and heating sector and we mainly deal with private customers and small local contractors. We also have a showroom for the fire, wood burning stove and fireplace side of the business.

The team consists of a managing director, operations manager, dedicated, staffed office and showroom team; two surveyors/estimators, two full time gas service engineers, a two-man fireplace installation team, five plumbing and heating engineers and 3 plumbing/heating engineer apprentices giving us the ability to cope with our growing customer base, totaling just over 8700 clients.

We're dedicated to customer satisfaction and to that end we are proud to be a member of Checkatrade and fully support its mission to help protect the public from rogue businesses.
