Our installation process

Thorough initial assessment

We begin with a comprehensive property survey to understand your heating requirements. Our engineers evaluate your current system, calculate heat loss, assess hot water usage, and examine radiator sizing. This detailed assessment ensures we recommend the most suitable boiler for your home and family's needs.

Transparent quotation

Following the survey, we provide detailed documentation outlining our recommended solution. This includes a complete breakdown of costs, system schematics, and projected timeline. We'll explain potential energy savings and discuss alternative options if applicable, ensuring you have all the information needed to make an informed decision.

Expert installation

Our installation process prioritises quality and safety at every step. We begin by protecting your property and carefully removing the existing system. The new installation includes system flushing, boiler fitting, control setup, and the addition of protective measures such as magnetic filters and scale reducers. Every installation concludes with rigorous testing and certification.

Comprehensive handover

Once installation is complete, we provide a thorough system demonstration and explanation of your new boiler's features. You'll receive digital copies of all certificates, warranty registration, and a planned maintenance schedule. We'll also ensure you have our emergency contact information and understand the optional service plans available.

Quality and protection

Our commitment to quality, transparency, and customer service ensures your new heating system will provide reliable comfort for years to come.

All our engineers hold Gas Safe registration and manufacturer approvals. We offer extended warranties of up to 12 years and maintain full insurance coverage. Every installation complies with current building regulations, giving you complete peace of mind.

To protect your investment, we install magnetic filters and treat your system with inhibitors. We offer scale prevention measures crucial for hard water areas and provide professional system flushing. Regular maintenance plans are available to ensure your boiler's continued efficient operation.
