Preparing for your boiler installation

Begin by clearing the area around your existing boiler for installer access and gather relevant documents such as service records and warranties.

Your installer should conduct a pre-installation survey to help them assess your heating needs, evaluate your current system, and choose the right boiler model for your home.

When selecting your boiler, consider your property's size, heating demands, and energy efficiency. Our find a boiler tool can support you with choosing the right product.

The day of installation: What to expect

On installation day, the process is efficient. Your installer will disconnect and safely remove the old boiler, and will dispose of it according to local regulations.

They will then install your new Worcester Bosch boiler, ensuring all components are properly connected, including pipework, wall fixings and controls.

Installation usually lasts from a few hours to a full day, depending on the complexity.

The installer will keep you updated and guide you on operating your new system.

Post-installation: ensuring optimal performance

Just like a car, a boiler needs to be well maintained in order to keep it operating at its best. We recommend a yearly boiler service to help ensure that your boiler is running as efficiently and safely as possible.
