Boiler Installation

Installation time varies by property and boiler type. A straightforward combi swap in a standard house can be completed in a day, while system or conventional installs that require cylinder work or pipe alterations may take longer. Your survey will confirm a realistic timescale before we start.

Yes — our engineers will safely isolate, remove and dispose of the old boiler and redundant pipework as part of the installation. Any hazardous waste is handled in line with regulations and included in your written job scope.

All new boilers supplied through JLN are registered with the manufacturer when required, providing the stated warranty. We also issue commissioning and Gas Safe paperwork at handover — keep these documents to protect your warranty and for future service calls.

Combi boilers suit small to medium homes with no cylinder; system boilers are better for high hot-water demand and storage cylinders; conventional boilers are chosen for older homes with traditional layouts.

Yes — we fit modern programmers, smart thermostats and weather compensation where appropriate. Correct controls improve comfort and reduce fuel use; during the survey we’ll advise which controls are compatible with your new boiler and whether they affect warranty terms.
