For an Irish home heated by oil, winter preparation includes the tank outside as well as the appliance indoors. A useful October task is to put the last inspection, the next service and any observations in one record, before deliveries become urgent.

OFTEC recommends a competent person's visual tank check during the annual appliance service, with regular visual checks between visits, especially after extreme weather. Concerns should go to an OFTEC-registered technician. [1]

Make the service conversation specific

Find the last invoice or service report. Was the tank included, or did the appointment cover only the heating appliance? Ask the technician what was inspected and whether any follow-up remains outstanding. An annual appointment on a calendar is less informative than a record of the work actually completed.

OFTEC's directory lets Irish households search by county and work type, including oil storage tanks and inspection or servicing. Check the relevant scope rather than assuming every listed business undertakes every task. [2]

Observe from a safe position

Between visits, use an ordinary ground-level view to note an apparent change in the tank or its surroundings. Record when you first noticed it and whether severe weather preceded it. Do not climb onto the tank, alter its fittings or try to repair a suspected leak yourself.

Keep delivery dates and quantities beside the service notes. The EPA identifies unusually frequent refilling as a possible warning of leakage; it is a reason to investigate, rather than a diagnosis that the tank is leaking. [3] Household use and weather can also change, so give the professional the records rather than relying on one impression.

A private well adds another concern

The EPA's drinking-water guidance highlights the risk from heating-oil tanks near wells. Ask a competent professional to assess the tank, spill containment and its relationship to the water supply. An internet photograph cannot establish whether an installation is suitable.

If a spill occurs, the EPA advises notifying the local authority and arranging testing of the well. [3] Keep those contact details accessible alongside the technician's number; do not improvise a clean-up or assume nearby water remains safe.

Before the next delivery, confirm access arrangements with the supplier and pass on unresolved concerns. The practical result should be a short, usable maintenance record: what was checked, what changed, who is dealing with it and when the next check is due.
