Installation dates and the time needed depend on the work involved and engineer availability. We’ll discuss these when arranging your installation.
Boiler installation costs and quotes
Replacing a combi in the same position involves different work from removing a cylinder, moving the boiler or installing a new roof flue. The price needs to reflect that scope, as well as the boiler you choose.
We look at the existing system before confirming the final quotation. For published guide ranges and a fuller explanation of the costs, see our boiler installation cost guide . If you are replacing an older boiler rather than changing the whole system type, see our boiler replacement in Croydon page.
Just comparing options? You can message us on WhatsApp with your postcode and current boiler model. Let us know whether you’re planning a replacement, a conversion or a move to another room.
Which boiler suits your home?
We’ll consider your heating needs, hot-water use and existing system. A larger boiler is not automatically the right answer, especially if the incoming water supply or pipework limits what the system can deliver.
Combi boilers
A combi provides heating and hot water without a separate hot-water cylinder. It can save space, but its suitability depends on mains flow and how many hot-water outlets you use together.
Read about combi boiler installation in Croydon , including changing from a system with a cylinder.
System boilers
A system boiler works with a separate hot-water cylinder. This can suit a household that needs stored hot water for several bathrooms.
We check the cylinder, controls and heating system together before recommending a replacement.
Regular boilers
Also called conventional or heat-only boilers, these are commonly part of an older setup with a cylinder and separate tanks.
Keeping that arrangement may be practical. We can also assess what would be involved in changing it.
Not sure you need a new boiler? An isolated fault may still be repairable. Start with our boiler repair service , read our new boiler or service guide , or see our boiler replacement advice if you’re weighing up repeated repair costs.
What size boiler does your property need?
Bedroom count alone does not tell us which boiler to fit. We consider the heat your property loses, the radiators it needs to supply and how your household uses hot water. A combi’s hot-water output also needs to be considered alongside its heating output.
Tell us if you regularly run more than one shower, have an extension or plan to add another bathroom. These details can change the recommendation even when the existing boiler has worked adequately in the past.
| Property or requirement | Option to consider | What we check |
|---|---|---|
| Flat or smaller home with one bathroom | A combi may suit the available space | Mains flow, water pressure, cupboard access and flue route |
| Two- or three-bedroom house | Combi or system boiler, depending on demand | Heat loss, radiators, bathrooms and existing pipework |
| Several bathrooms used together | A system with stored hot water may be appropriate | Simultaneous demand, cylinder capacity and incoming supply |
| Older or converted property | Assess the existing system before choosing | Altered pipework, gas supply, pressure, access and boiler position |
What we check before recommending a boiler
The assessment covers the current appliance and cylinder, radiator condition, heating controls, gas supply, mains water supply, flue position and condensate drainage. We also consider access for installation and future servicing.
If you want a combi conversion, we discuss what happens to the existing cylinder and tanks, which pipework needs changing and whether the water supply supports the hot-water use you expect. Freeing up a cupboard is useful, but the new system still needs to work for your household.
What does installation include?
The accepted quotation sets out your installation’s scope. We discuss the work needed around the appliance so you know which items are included and which are additional.
Fitting and system checks
- Safe removal of the old boiler where agreed
- Fitting the selected appliance and compatible controls
- Checks to the gas supply, flue and condensate route
- Agreed pipework changes, appropriate system cleaning and inhibitor protection
- Testing, commissioning and operating checks
Handover and documentation
- A demonstration of the boiler and heating controls
- Relevant installation and commissioning records
- Applicable registration and warranty information
- Agreed removal of the old appliance and waste
- Access left for future servicing and repairs
Leave room for servicing
A new boiler needs suitable access after installation, including when it is fitted inside a cupboard. We consider that access alongside the flue and pipework routes. If you plan to box in the appliance or change the surrounding kitchen units, discuss this before the installation is agreed.
Ask which filter, thermostat and cleaning method your quotation includes. A power flush or extra radiator work should be specified where required, rather than assumed.
More detail: installation certificates and paperwork . If additional cleaning or radiator work is required, we’ll explain that separately as part of the quotation.
How we arrange your installation

Share your postcode, current setup and what you want to change. Use the online quote form, call or WhatsApp.
Assess the property
We check heating and hot-water demand, water supply, pipework, boiler position, flue route and access.
Agree the work
We explain the recommended boiler and quotation. The scope, installation date and expected duration are agreed before work starts.
Install and explain
We fit and commission the boiler, demonstrate the controls and explain the documentation and next steps.
Before installation day, we’ll discuss access to the boiler and any other parts of the property needed for the work. Tell us about parking restrictions, tenant access or a shared building entrance when booking, so these can be considered in the arrangements.
A straightforward swap can often take one working day. Conversions, relocations and more involved flue work can take longer. See what affects installation time .

Check the warranty for the model you choose
Ask us to confirm the cover available with your selected boiler, who provides it and any registration or servicing conditions. Warranty terms can differ between models and installation packages.
Keep the installation documents and warranty details together after handover. Check the ongoing servicing requirements for the chosen model and arrange servicing accordingly. A manufacturer’s warranty and any installation workmanship cover may have different terms; ask what each includes before accepting the quotation.

Boiler installation questions
Can I get a quote before choosing a boiler?
Yes. Tell us about your property and current heating system. We can discuss suitable boiler types and models as part of the quotation process. You don’t need to choose the model first.
Do you provide free boiler quotes?
Yes. You can request a free quotation through our online boiler quote form , or call 020 3576 6769 to discuss the work. The final quotation depends on the installation requirements.
Will my heating and hot water be off during installation?
There will be an interruption while the existing boiler is disconnected and the new one is connected and tested. Ask us about the expected downtime for your job, especially if a conversion or relocation is planned.
Can you move the boiler to another room?
We can assess a new location. It needs a suitable flue route, gas supply, condensate drainage and access for maintenance. Moving the appliance can add pipework and other work, which should be included in the quotation.
Do I need new radiators as well?
Not necessarily. We assess the existing heating system and discuss any issues that need attention. Cleaning, controls or individual radiator changes may be relevant; replacing the boiler does not automatically mean replacing every radiator.
Can I keep my existing heating controls?
Sometimes, depending on their condition and compatibility with the selected boiler. We assess the controls as part of the installation and explain any recommended changes. If you want a smart thermostat, mention this before the quotation is finalised so the required equipment and setup can be included.
Does every new boiler need a power flush?
The cleaning method depends on the system’s condition and the appliance requirements. We consider signs of sludge, poor circulation and uneven heating before recommending the work. Ask which cleaning method and protective treatment are included in your quote; a power flush should not be assumed to be part of every installation.
What paperwork will I receive?
Ask us to explain the commissioning records, applicable registration and warranty information for your installation at handover. Keep these with the boiler instructions for future servicing and reference. Our boiler installation certificate guide explains the documents in more detail.
Do you install boilers for landlords?
Yes. We install replacement and new boilers in rental properties. Tell us about tenant access and any timing requirements when requesting the quote, so these can be considered when arranging the work.
