Do you remove the old boiler and dispose of it?

Yes. Our engineers remove the old boiler and carry out responsible disposal or recycling as part of the installation. We also safely disconnect the oil feed and leave the work area tidy.

Will the installation be certified?

All oil boiler installations are commissioned and issued with the appropriate OFTEC documentation and any required Building Regulations notices. We leave you with certification and operational guidance.

What about my oil tank — do I need a new one?

We always assess tank condition during the survey. If the tank shows corrosion, poor siting, or lacks a bund (where required), we’ll recommend repair or replacement and explain the options and legal considerations for safe storage.

Do I need ongoing servicing after installation?

Yes. Annual servicing keeps oil boilers running efficiently and helps preserve warranties. We offer boiler servicing and service plans tailored to oil systems to reduce breakdown risk and prolong boiler life.

What we install and why it matters. Modern condensing oil boilers significantly improve efficiency and reduce running noise compared with older plant. Pro Plumbers Ltd handles the full scope: careful removal of the old boiler, installation of the new condensing unit, flue works (including lining or new twin‑wall flues where required), safe connection of the oil feed and integration with your hot water cylinder or system controls.

Included in a typical installation:

Property survey and system specification
Removal and responsible disposal of the old boiler
Flue works, chimney lining or new flue as needed
Oil line checks, tank condition assessment and advice on bunding or replacement
Commissioning, testing and OFTEC/Building Regs paperwork

Local expertise and aftercare. We work across Sevenoaks, Tonbridge and Tunbridge Wells and are used to the practical challenges of Kent properties — long flue runs, restricted access and older tanks. All installations are backed by our one‑year workmanship guarantee and clear commissioning notes so you know how to operate your controls.
