What Happens During Your Boiler Installation?

As a small local Cupar, Fife company, our reputation is invaluable to us. That’s why we respect your home and lay down dust sheets to protect your flooring. We then remove the old boiler and dispose of it. Your new boiler will be installed according to manufacturer’s instructions. Once the new boiler has been commissioned, we show you how to operate it, clean up any mess that was made then register your new boiler warranty.

Pre-Installation Survey & Planning

Before any work begins, our Gas Safe registered engineers conduct a thorough heating system assessment of your property. We evaluate your existing pipework, radiators, and hot water requirements to ensure your new boiler is correctly sized for optimal efficiency. This initial survey helps us identify any additional work needed, such as powerflush services or radiator upgrades, ensuring your entire central heating system works harmoniously.

Day of Installation – What to Expect

Morning Preparation (8:00-8;30 AM) Our qualified heating engineers arrive with all necessary equipment and materials. We’ll introduce ourselves, explain the day’s schedule, and set up protective coverings throughout the work area. All flooring, furniture, and surfaces near the installation area are carefully protected.

Safe Removal & Disposal (8:30-10:00 AM) Your old boiler system is safely disconnected from the gas supply, electrical connections, and water pipes. We handle the complete removal and environmentally responsible disposal of your old equipment, including any redundant pipework or components.

New Boiler Installation (10:00 AM-1:00 PM) Installation of your new energy-efficient boiler begins with precise positioning and secure mounting. Our experienced gas engineers connect all pipework, ensuring proper flow and return connections. Gas supply pipes are connected and tested for safety, while electrical connections are made to current regulations. We install the flue system with appropriate weatherproofing and termination.

System Integration & Testing (1:00-3:30 PM) Your new boiler is integrated with existing radiators and hot water systems. We conduct comprehensive safety checks including gas tightness testing, flue analysis, and operational testing of all heating controls. The system is filled, pressurized, and balanced for optimal performance across all radiators.

Commissioning & Handover (3:30-4:30 PM) Once installation is complete, we commission your new heating system, programming the controls and setting optimal operating parameters. You’ll receive a comprehensive demonstration of your new boiler’s operation, including how to adjust temperature settings, reset procedures, and basic maintenance tips. We provide all manufacturer documentation, warranty registration, and your Gas Safe installation certificate.

Post-Installation Service

Before leaving, we ensure your property is left clean and tidy, with all debris removed and work areas restored. Your new boiler warranty is registered with the manufacturer, and we schedule your first annual service to maintain optimal performance and efficiency throughout the Fife heating season.
