New boiler with copper pipework and a heating manifold below it

Boiler Installation Worthing Homeowners Can Trust

Our boiler installation Worthing service gives you a new, efficient boiler fitted by Gas Safe engineers, at a fixed price agreed before we start.

We look at your home, your hot water needs and your existing pipework, then recommend a boiler that suits them rather than the most expensive one.

Whether you need a like-for-like combi swap or a change of system, Plumb Guys Ltd plans the job carefully, keeps disruption to a minimum and leaves the area clean. Every installation comes with a power flush, controls, filter, pipework and paperwork included.

Fixed-price boiler installs with everything included


Combi Boiler Replacement

A combi boiler heats your water as you need it, so there is no hot water cylinder or cold water tank to find room for.

Plumb Guys Ltd replaces old combi boilers with modern, efficient models, and can convert an older system to a combi where it suits your home.

We check that a combi suits your home's hot water needs before you commit, so it keeps up with your showers and taps.

New Boiler Installation Services

Our new boiler installation service covers every type of gas boiler, from compact combis for flats to system and regular boilers for larger homes with more than one bathroom. We remove your old boiler, fit the new one and set up your heating controls.

Every installation is planned around your home and daily routine. Our engineers explain how to use the new boiler and controls before they leave, so you are comfortable with everything from day one.

Combi Boilers

Combi boilers suit most flats and smaller homes, giving instant hot water and heating from one compact unit.

We size the boiler to your home and check the gas supply and water pressure, so it performs as it should.

System Boilers

System boilers work with a hot water cylinder, which makes them a good choice for homes with more than one bathroom.

We fit the boiler and the parts that go with it, and can supply an unvented cylinder where your home needs one.

Regular Boilers

Regular, or conventional, boilers suit older homes that already have a cold water tank and a hot water cylinder.

We can replace a regular boiler like for like, or talk you through changing to a different system if it suits you better.

Power Flush or System Clean

Sludge and debris in old pipework and radiators can shorten the life of a new boiler.

We clean your heating system as part of every installation and add inhibitor, so the new boiler starts with clean water.

Smart Heating Controls

Modern controls make it easier to heat your home only when you need it.

We fit and set up thermostats and smart controls from Nest, Hive, Honeywell and EPH, and show you how to use them.

Magnetic System Filters

A magnetic filter catches loose particles before they reach the boiler.

We fit one with every new boiler to help protect it and keep your heating running efficiently for longer.

Manufacturer's warranty of 5 to 12 years, depending on the boiler
