Last reviewed: by Alan Kemish Plumbing, Heating & Fires.
Our boiler installation in Emsworth starts with a survey of your existing boiler, pipework, flue route and hot water needs. We then recommend a boiler type and size that suits your home, not the biggest one we can sell.
We also fit boilers in Havant, Hayling Island, Westbourne, Southbourne and nearby towns. If you are not sure whether your old boiler needs replacing, our boiler servicing and repair service is a good first step.

What does boiler installation in Emsworth include?
A boiler installation in Emsworth covers everything from the survey to handing over the paperwork. Each job follows the same steps:
- Survey: we check your current boiler, gas supply, flue route, pipework and how much hot water you use.
- Quote: we recommend a boiler and controls and give you a written, no-obligation price.
- Remove the old boiler: we drain down the system and take out the old boiler safely.
- Fit the new boiler: we install the boiler, flue and condensate pipe, and upgrade pipework where needed.
- Clean and protect the system: we clean the system water and, where suitable, fit a magnetic system filter.
- Commission and hand over: we test the boiler, set up the controls, show you how they work and give you the paperwork.
How do I know if my boiler needs replacing?
A boiler usually needs replacing when repairs become frequent, parts are hard to get, or it no longer heats your home well. Common signs include:
- The boiler breaks down more than once a year, or the same fault keeps coming back.
- Replacement parts are no longer made for your model.
- Your heating bills keep rising even though you use the heating the same way.
- Radiators take a long time to warm up, or hot water runs cold.
- The boiler is an old non-condensing model with a permanent pilot light.
If you see soot, staining or a lazy yellow or orange flame, turn the boiler off and call the National Gas Emergency Service on 0800 111 999 if you smell gas.
Which type of boiler is right for my home?
The right boiler depends on how many bathrooms you have, your water pressure and whether you have space for a hot water cylinder. This table compares the three main types:
| Boiler type | How it works | Usually suits |
|---|---|---|
| Combi boiler | Heats water on demand from the mains. No hot water cylinder or loft tank. | Flats and homes with one bathroom and good mains pressure. |
| System boiler | Heats a hot water cylinder. Most parts are inside the boiler; no loft tank. | Homes with two or more bathrooms that use hot water at the same time. |
| Regular (heat-only) boiler | Works with a hot water cylinder and cold water tanks in the loft. | Older homes with existing tanks, or low mains pressure. |
If you have a hot water cylinder, see our central heating and hot water cylinder work for options such as unvented cylinders.
How long does a boiler installation take?
A like-for-like boiler replacement usually takes one to two days. Moving the boiler to a new room, changing from a regular to a combi boiler, or replacing old pipework can add a day or more. We confirm the timescale with your quote so you know how long the heating and hot water will be off.
What paperwork will I get after a new boiler is fitted?
After a gas boiler is installed, the installation should be notified under Building Regulations through the Gas Safe Register, and you then receive a Building Regulations Compliance Certificate by post. You should also get a completed commissioning checklist, often called the Benchmark checklist, and details of how to register the manufacturer's warranty.

Boiler installation in Emsworth: frequently asked questions
How much does boiler installation in Emsworth cost?
The cost of boiler installation in Emsworth depends on the boiler type and size, whether it stays in the same place, the flue route and how much pipework needs upgrading. We price every job individually after a survey. Your quote is free and comes with no obligation.
Can you move my boiler to a different room?
Yes, a boiler can often be moved, for example from a kitchen to a cupboard or loft. Moving it means new gas, water, condensate and flue routes, so the job takes longer than a straight swap. We check what is possible during the survey.
Do I need to be at home while the boiler is fitted?
Someone needs to let us in at the start and be available at the end so we can show you the new controls. Your heating and hot water will be off for part of the installation, so we agree the timing with you in advance.
Will a new boiler lower my energy bills?
A modern condensing boiler is usually more efficient than an old non-condensing one, so most people use less gas. How much you save depends on your old boiler, your insulation and your controls. Good controls such as a programmable thermostat and radiator valves help too.
What warranty comes with a new boiler?
New boilers come with a manufacturer warranty, and the length depends on the make and model. Most warranties need the boiler to be registered and serviced every year. We tell you the warranty for the boiler we recommend when we quote.
