A new boiler installation involves more than fitting the appliance itself. The work required depends on your existing heating system and the type of installation, but we make sure the necessary installation, testing and handover are considered as part of the job.
A typical boiler installation may include:
The exact work varies between properties. Boiler relocation, system conversion or additional heating-system work will be discussed during the assessment and included in the quotation where required.
If your existing boiler is unreliable or no longer suitable for your property, replacing it can provide an opportunity to improve the performance and control of your heating system.
We provide fast, reliable plumbing and heating services across South West and Central London, covering both residential and commercial properties.
The cost of a new boiler installation depends on the type and model of boiler, your property's heating and hot water requirements, and the amount of installation work involved.
A straightforward boiler replacement will usually involve less work than relocating a boiler, converting from a conventional system to a combi boiler, or making significant changes to existing pipework.
Keystone London assesses your requirements before providing a clear quotation, so you know what is included before installation begins.
A straightforward boiler replacement can often be completed within a day, while more complex installations may take longer.
Changing the boiler type, moving it to a new location, altering pipework or upgrading other parts of the heating system can increase the installation time. We'll explain the expected timescale before work begins.
The correct boiler size depends on more than the number of bedrooms in your property. Your home's heat demand, number of radiators, bathrooms, hot water requirements and existing heating system all need to be considered.
Our engineers assess these factors before recommending an appropriate boiler output for your property.
The best boiler type depends on your property and how you use heating and hot water.
A combi boiler can be a practical option for properties with suitable water flow and moderate hot water demand. System boilers work with a hot water cylinder and can suit homes requiring stored hot water, while conventional boilers may be appropriate for certain existing heating-system configurations.
We'll assess your current system and explain which options are suitable.
In many properties, yes. However, relocating a boiler can require changes to gas pipework, heating pipes, condensate drainage and the flue arrangement.
The proposed location also needs to meet relevant installation and safety requirements. We can assess suitable locations during your survey and explain any additional work involved.
Not necessarily. If your existing radiators are in good condition, appropriately sized and working effectively, they may not need replacing.
However, poorly performing, damaged or unsuitable radiators may be worth upgrading as part of a wider heating-system improvement. We'll assess the existing system and advise if any changes are recommended.
The condition of the existing heating system needs to be considered when installing a new boiler. Sludge and debris within the system can affect circulation and the performance of new components.
The appropriate cleaning or flushing method depends on the condition of the system. We'll advise what is required as part of the installation.
Keystone London works with leading boiler manufacturers commonly installed in UK homes, including brands such as Worcester Bosch, Vaillant, Ideal, Baxi and Viessmann.
Rather than recommending the same boiler for every property, we consider your heating requirements, hot water demand, available space, budget and preferred features.
New boilers generally come with a manufacturer's warranty, although the length and conditions vary between manufacturers and models.
Correct installation, registration and ongoing servicing may be required to maintain warranty cover. We'll explain the relevant requirements for the boiler you choose.
A boiler should generally be serviced once every 12 months. Regular servicing helps check that the appliance is operating safely and correctly, can identify developing problems and may be required under the manufacturer's warranty conditions.
Keystone London also offers annual boiler servicing and service reminders to help keep maintenance on schedule.
Yes. Keystone London provides boiler installation across West, South West and Central London, including areas such as Chelsea, Fulham, Kensington, Knightsbridge, Pimlico, Hammersmith, Chiswick, Ealing, Putney, Wandsworth and surrounding areas.
Replacement isn't always necessary when a boiler develops a fault. A repair may make more sense if the boiler is otherwise reliable and the problem can be resolved economically.
A new boiler may become worth considering when the existing appliance is ageing, experiencing repeated breakdowns, becoming expensive to repair or no longer meeting your property's heating and hot water requirements.
