Boiler Installation
Choose a gas or oil boiler installation planned around your home, not simply the appliance on the wall. Pro Plumbers is a Worcester Bosch accredited installer serving Sevenoaks and the surrounding area.
ABOUT THIS SERVICE
A replacement boiler matched to your home
Replacing a boiler is an opportunity to check whether the existing arrangement still suits your household. Pro Plumbers considers hot water demand, heating requirements, available space and the condition of connected pipework before recommending an installation. We fit Worcester Bosch and Vaillant boilers, and our Worcester Bosch accredited installer status applies specifically to that brand. Our team holds Gas Safe and OFTEC qualifications for the relevant gas and oil work. You can explore our separate gas boiler installation and oil boiler installation pages for fuel-specific information, or contact us if you are unsure which route applies. With 15 years trading, we aim to make the choices understandable, explain practical constraints and provide a fixed, no-obligation price for the larger installation job. We also outline the expected disruption before agreeing a date.
Minimum charge £90 + VAT, including the first hour on site. Larger jobs get a fixed, no-obligation price.

BENEFITS
Why Choose us for Boiler Installation?
Gas and oil expertise
Gas Safe and OFTEC qualifications support installations suited to the fuel and appliance involved.
Worcester Bosch accredited installer
We are a Worcester Bosch accredited installer and also fit Vaillant boilers, giving you a choice to discuss.
Workmanship cover
Your installation workmanship has a 1-year guarantee, with any separate manufacturer cover explained for the chosen appliance.
Choosing between gas and oil installation
The right starting point is the fuel already serving the property and whether the existing system meets your needs. A mains gas home and an oil-heated village property can have quite different installation considerations. Our separate gas boiler installation and oil boiler installation pages explain those routes in more detail. If you are comparing options, we can discuss the practical requirements rather than assuming that every replacement follows the same pattern.
For either fuel, appliance selection needs to reflect the home rather than a headline output alone. The number of bathrooms, patterns of hot water use and the existing cylinder arrangement can all influence the recommendation. We ask about how you actually use the property, including rooms that are difficult to heat, so the installation proposal addresses real needs rather than merely replacing a model with something similar.
What we check before fitting
An assessment looks at the proposed boiler location, relevant connections, controls and access for the installation and future servicing. Existing components may be suitable to retain, while other items may need attention as part of the job. We explain those findings and identify what is included in the price. If you want to relocate the boiler, mention that early because the associated work can change the scope considerably.
Keeping an existing hot water cylinder or moving to another system arrangement deserves careful discussion. Space, water supply characteristics and household demand all matter. Our G3 unvented qualification is relevant where unvented hot water work forms part of the project. We will distinguish necessary installation work from optional improvements, allowing you to make an informed decision without being presented with a list of unexplained extras.
An organised installation and useful handover
We discuss access, likely interruption to heating and hot water, and the order of work before the installation begins. The engineer needs suitable access to the appliance location and any areas involved in connecting the system. We cannot promise an identical installation time for every home: a straightforward replacement and a relocation with alterations are different jobs. Your agreed plan should reflect the work actually required at your property.
After fitting, appropriate commissioning and safety checks are followed by a practical explanation of the controls. We discuss servicing requirements and the terms of any appliance warranty rather than assuming all manufacturers offer identical cover. Pro Plumbers provides a 1-year workmanship guarantee. Based at 11 Lime Tree Walk, Sevenoaks TN13 1YH, we cover Tonbridge, Tunbridge Wells and surrounding villages within roughly 20 miles. Call 01732 444555 to discuss an assessment.
