Sean Connolly2024-11-26 Fantastic service, Quick response. Martin Hamill2024-11-14 We have been a client of Barton for a number of years. The existing Clubhouse telecoms and broadband were no longer fit for requirements, Barton brought me up to speed re forthcoming changes to the telecoms network and then advised on alternatives to our existing systems. Not only was advice valuable, their suggested project costs were very competitive. These, when combined with their good service levels, made them a compelling choice.
