As noted by Notmything, meter-readings were discontinued between March and May - initially this applied to indoor meters only, then all meters.
The restriction has now been lifted in relation to outdoor meters.
Under normal circumstances, ESB Networks read an electricity meter for four out of the six annual bills, provided they are able to access the meter. If the bill is continuously being estimated, we recommend checking with the property owner or agency regarding access to the meter to take an up-to-date reading.
