Frequently asked questions about OFTEC Certificate

Is OFTEC registration required to install an oil boiler?
Not legally required, but without OFTEC registration you must apply to Building Control separately (which is slower and more expensive). OFTEC registration lets you self-certify the installation.
Do oil boilers need annual servicing?
Yes. OFTEC recommends annual servicing. Unlike gas, there is no legal landlord inspection requirement for oil, but regular servicing is essential for safety and efficiency.
