Services
New Boiler Installation
We specialise in installing A-rated gas boilers from leading manufacturers, including combi, system, and traditional models. Our installations include flues, thermostats, and pipework with a workmanship warranty. Upgrading to a modern boiler improves energy efficiency and reduces heating bills by up to 840 annually. All installations comply with Gas Safe regulations and include a free smart controller.
Air Source Heat Pumps
We install energy-efficient air source heat pumps that reduce carbon footprints and heating costs. These systems extract warmth from ambient air to provide year-round heating for residential properties. Ideal for off-grid homes, they offer continuous low-temperature heating with minimal maintenance. Our engineers are approved installers covering West Sussex and surrounding areas.
Boiler Servicing
Our Gas Safe engineers perform comprehensive boiler services to ensure safe, efficient operation. The service includes inspection, cleaning, and testing of components with no corners cut. Regular maintenance extends boiler lifespan and maintains warranty validity. We offer care plans to spread maintenance costs over the year.
Powerflushing
Professional powerflushing removes sludge and debris from central heating systems, improving water flow and heat distribution. The process restores system efficiency and prevents future breakdowns. Recommended during boiler replacements or when radiators show cold spots, our technicians use industry-standard equipment for thorough system cleansing.
Unvented Cylinder Installation
We supply and install high-pressure unvented cylinders that deliver mains-pressure hot water without cold water tanks. These space-saving systems provide powerful showers and consistent water pressure for multiple outlets. Our Gas Safe engineers ensure safe installation compliant with building regulations, ideal for modernising older properties.

Jun 08, 2020 Report
Had an amazing full bathroom install experience with Plumbguys, came as a word of mouth recommendation through our Carpet Fitters who were also excellent so we knew they were going to be a safe bet. From concept design stage Guy worked closely with us to realise the vision we had for the build and advised us where we should invest in quality parts and where we could make savings to meet our budget.

Couldn't be happier with the completed build, it ran over a bit but only because I'm a fussy customer and changed my mind on the sink that had already been installed, but it wasn't a problem and they
