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.
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.
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.
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.

Our engineers are trained on all major boiler brands and stay current with the latest heating technology and Scottish building regulations.
Professional Installation Standards
Every boiler installation is completed to the highest industry standards, with thorough system commissioning, safety testing, and customer handover training. We’re committed to leaving your home cleaner than we found it, with complete waste removal and careful protection of your property throughout the installation process.
Most boiler installations are completed in a single day, typically taking 7-8 hours from start to finish. We arrive at 8:00 AM and you’ll have heating and hot water restored by late afternoon. If your property needs additional work like relocating pipework or a powerflush, we’ll let you know during the survey so there are no surprises.
Your heating and hot water will be off while we’re installing your new boiler, but we work efficiently to get everything back up and running the same day. By evening, you’ll have a brand new, efficient heating system keeping your home warm with plenty of hot water. We know it’s an inconvenience, so we make it as quick as possible!
Very little! Just clear a path to your existing boiler and move any valuables or breakables from the area. We’ll take care of the rest – we bring dust sheets to protect your floors and furniture, and we’ll leave your home clean and tidy. If you have any concerns about access or where to park, just give us a quick call beforehand.
We’re specialists in Worcester Bosch, Navien, Baxi, Ideal, and Glowworm – all trusted brands with excellent track records. Rather than pushing one brand, we’ll recommend the best boiler for your home based on your property size, hot water needs, and budget. All options come with strong manufacturer warranties (5-10 years), so you’re covered whatever you choose.
Absolutely! Modern A-rated boilers are significantly more efficient than older models. If your current boiler is over 10-15 years old, you could see heating bill reductions of approximately 25%. That means more money in your pocket each month, plus a warmer, more comfortable home. The savings really add up over time.
Everything you need for a complete installation! This includes: removal and environmentally responsible disposal of your old boiler, installation of your new A-rated boiler with all pipework and connections, Gas Safe certification, a free wireless programmable thermostat, a magnetic filter (£200 value), full system testing and commissioning, demonstration of how to use your new boiler, and manufacturer warranty registration. No hidden costs – just straightforward, honest pricing.
