Frequently Asked Questions 

What is One Big Switch?

One Big Switch is a consumer network which uses its combined people power to unlock group discounted offers on various household bills.

What household bills has there been an offer for so far?

Since early 2014, One Big Switch has used the huge people power of nearly 100,000 members to unlock group discounted offers on household energy health insurance, mortgage protection insurance, mortgages, home insurance and broadband and in doing so, has helped tens of thousands of Irish households save on their household bills.

What household bills might there be an offer for in the future?

Subject to ensuring we comply with the relevant licencing or regulatory environment, we’re always out and about trying to source offers for our members.

What is the Big Cost of Living Switch?

The Big Cost of Living Switch is a campaign that aims to unlock group discounted energy and insurances offers for consumers using the buying power of tens of thousands of householders. The campaign is powered by One Big Switch.

The Big Cost of Living Switch campaign aims to:

• Signing up 20,000 consumers in the next 4 weeks willing to switch together.
• Use their collective buying power to negotiate discounted energy and insurances offers.
• Make those group-discounted offers available to those who join the campaign.

How does it work?

There are 3 simple steps:

  1. You register to demonstrate your support. It only takes a few moments, it costs nothing and you are not obliged to take up any offers we negotiate.
  2. We source the offers. We use the massive buying power of the campaign to unlock group discounted energy and insurances.
  3. You decide. We email you any offers we manage to unlock and you can apply if you decide the offer is right for you.

Do I have to switch to One Big Switch offers if I join?

Joining One Big Switch is obligation and cost free. You just decide if the offer is right for you. One Big Switch members are free to use our offers as leverage to shop around, or to see if they can get a better deal from their existing providers.

Are One Big Switch offers the cheapest offers around?

Not necessarily. Any Big Switch is a bold experiment to see if we can source offers that you can’t get as an individual. Some customers are on legacy deals and special deals that are not available cost-free to the general public. Other providers could also be compelled to compete with One Big Switch offers by offering more competitive offers, which is great. It means consumers win even more. One Big Switch campaigns are about driving competition.

Are One Big Switch offers the right products for me?

Not necessarily. You should always shop around. People who join One Big Switch campaigns can switch to a negotiated offer, use the offer to shop around, or even negotiate with their current provider.

How is One Big Switch different from price comparison websites?

One Big Switch creates products and prices we don’t compare them. We use the power of our members to unlock offers on essential household expenditure items. We only forward offers to our members that are not available to individuals.

Will One Big Switch swamp me with emails?

Nope. We know our members are busy; we won’t waste your time with daily emails. When we can help you cut the cost of your household bills we will be in touch. When we can’t, we won’t. Also, It’s easy to unsubscribe.

Does it cost anything to take part in One Big Switch Campaigns? I

t costs nothing to take part in One Big Switch campaigns. It is free to join, and free to take part.

So how does One Big Switch pay its bills?

We make money when you save money. One Big Switch is a for-profit-with-purpose enterprise that earns a fee from the businesses that earn customers through our campaigns. Those commissions help to fund our future campaigns. Providers pay these fees not our members.
