Mark Wijesinghe

Having originally started his business as Graduate Gas and known on Facebook as Mr Plumberman, Mark Wijesinghe provides high quality, dependable boiler and bathroom fitting and maintenance services, generally by word of mouth recommendations.

Mark works in and around the Cheltenham area. He is a sole trader so it is usually not convenient for him to answer phone calls - instead drop him an email to or text 07717 741075 to enquire, ideally with photographs of the bathroom, boiler or project in question. He's usually booked up several weeks or months in advance, so ideally plan well ahead for your new bathroom or work that needs doing.

Mark may be able to attend emergency call-outs, subject to availability.

'He can do anything and his easygoing personality makes him a pleasure to have around.' - Shan Weerasiri


Mark has an engineering degree as well as years of experience and up-to-date qualifications and accreditations.


When you are having a new bathroom fitted, a perfectionist is the best person for the job.
