FAQ
Frequently Asked Questions
How long does an oil boiler installation take?
Typical installations take one to three days depending on access, whether the flue needs relining or a new flue is required, and if the oil tank must be moved or replaced. Your site survey will confirm a realistic programme and any temporary heating arrangements needed.
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.
