A Review of the One Big Switch Energy Offers.

One Big Switch has a couple of new energy switching offers running at the moment. (Feb 2021)


Dual Fuel Offer


The discounted dual fuel offer from OneBigSwitch, with Energia, works out at €1417 in year one for average usage. This is €47 more expensive than going direct to Energia (€1374) .
But the One Big Switch offer includes an offer of a free gas boiler service by Energia which normally costs €95. (The average price of a gas boiler service is about €73.)
So – this offer with the boiler service does work out cheaper than going direct to Energia IF you have a gas boiler. The boiler service appointments are “subject to availability” – so you might not get one as soon as you need it.
Gas boilers should be serviced annually by a Registered Gas Installer. (RGI).

Electricity Offer

The OneBigSwitch electricity offer is also with Energia and it works out at €852 in year one. This is €72 more expensive than going direct to Energia (€780).
However – with the One Big Switch offer you get a FREE Google Nest Audio smart speaker worth €99. So if you want one of these – this deal is a good one for you.
