  • Paul Holmes

    Managing Director

    Paul Holmes is an experienced company director who has worked in both public and private sector during his thirty-year career.

    Before founding XP Plumbing and Heating five years ago, Paul was the director of a number of other successful companies. He has a proven track record of establishing and growing companies in a wide variety of service-based industries, including security systems, electronics, and project management.

    As well as providing the strategic direction, Paul is also XP’s company secretary.

    In his spare time, Paul takes a keen interest in third sector issues. He is a Freeman of the City of London and a member The Worshipful Company of Security Professionals, the 108th Livery Company in the City. He also enjoys watching rugby and playing golf.

  • Sasha McMullin

    Finance Manager

    Sasha is XP’s finance manager, and is responsible for the company’s financial affairs. Sasha is a finance professional and has extensive accountancy experience in both the private, public, and third sector, and plays a key role in the smooth running of XP’s office. She handles all of XP’s invoicing and payments, and reports to the managing director.

    In what spare time remains, Sasha is fully occupied looking after her family… and supporting Australia in international sporting events!

  • Sam Dowling

    Plumbing and Gas Engineer

    Sam is a versatile plumbing and heating engineer, with more than ten years industry experience.

    He joined XP over a year ago, and was previously with P&R Installations, where he was a gas engineer. Sam also has considerable experience of some of the larger-scale projects XP handles, like managing bathroom installations.

    Like many of his colleagues at XP, Sam is a keen rugby fan.

  • Connor McWilliams


    Connor joined XP earlier this year and is a qualified electrician. Before joining XP, Connor was a contractor for the major property agent Savills.

    He has recently been engaged in XP’s major project for the Metropolitan Housing Trust, installing fire alarms and emergency lighting.

    Unlike the majority of the company, Connor prefers football to rugby – and therefore relies on the quality of his work to make up for the lack of popularity his choice of sports brings!

  • Harry King

    Electrical Projects

    Harry joined the company a year and a half ago from EMS PLC, and is responsible for all XP’s electrical works. He has undertaken a wide range of projects for XP, from day-to-day installations to major undertakings for large managing agents like Foxtons and the Metropolitan Housing Trust.

    Harry also manages XP Plumbing and Heating’s apprenticeship programme.

    In his limited spare time, Harry is a keen rugby player and all-round sportsman.

  • George Sullivan

    XP Service Manager

    George has been with XP Plumbing and Heating for over two years – and is responsible for the company’s day-to-day liaison with clients. As the first point of contact for new customers, George is very much the public face of the business.

    XP prides itself on the strength and quality of its office-based team, in which George plays a pivotal role. Whether you wish to discuss a new job, or are an existing customer, it’s likely that George will be your key contact.

    George’s outside interests include keeping fit, boxing, and visiting his local gym.

  • Harry the Dog

    Marketing and Publicity

    Harry is XP’s marketing and publicity guru (or at least he thinks he is). His pedigree is impeccable - just don’t suggest he only got the job because he lives with the managing director and his wife.

    Over the past year, he’s regularly appeared in the local paper, and has a resident hoarding in Station Road, Sidcup. The pinnacle of his fame to date is a huge hoarding at Sidcup train station, where he appears with the XP engineers and members of Sidcup Rugby Club (which XP sponsor).

    At heart, Harry’s an armchair sports dog, but he also enjoys (short) walks, and visits to pubs that will let him in.

    If you see Harry around south London, or at his country retreat in Swanage, do stop him for a chat.
