It may be the first time you're hearing the term 'micro business'. In fact, most SMEs fall into this category in the eyes of business energy suppliers without realising. There's a few benefits to being classed as a micro business; but as with anything it does have its drawbacks.
You'll be classed as a micro business by energy suppliers if you fit into one of the following categories:
you employ less than 10 employees and have an annual turnover no greater than €2 million; or
use less than 100,000 kWh of electricity per year; or
use less than 293,000 kWh of gas per year.
