QUICK ANSWERS
What does boiler installation include?
It usually covers the boiler, connection to the heating system, commissioning checks and handover guidance. Pipework, controls and system upgrades may be quoted separately depending on the property.
How much does a new boiler installation cost in London?
Price depends on the boiler type, property size, existing pipework and whether a full system upgrade is needed. A like-for-like replacement is usually simpler than a full heating redesign.
Do you install boilers for homeowners and landlords?
Yes. This service is relevant to homeowners, landlords and property managers who need a new or replacement boiler fitted in a safe and compliant way.
What a GBS actually records.
A new boiler installation is often the right choice when an existing boiler is old, unreliable or no longer efficient enough for the property. It may also be needed when a home is undergoing a heating upgrade or a replacement is required after a failed or ageing system.
The exact requirements depend on the property layout, the current heating circuit, boiler output, and whether the installation is a straight swap or a more involved system change. A proper installation should be planned around capacity, efficiency and safe operation rather than only the purchase price.
A professional installation will look at the boiler location, flue route, controls, ventilation and the condition of the existing pipework before the job is confirmed. This helps avoid costly surprises or performance issues later on.

Asked about Gas & Boiler Installation.
Common signs include frequent breakdowns, poor heat output, rising energy bills, noisy operation or a boiler that is reaching the end of its expected life. A survey can confirm whether a replacement is the right option.
Often yes, especially in a straightforward replacement. In other cases, the existing pipework, controls or radiators may need attention to support a more efficient boiler.
No. A service is scheduled maintenance for an existing boiler that is still working. Installation is the fitting of a new or replacement unit as part of a larger project.
