I spoke with a few comparison sites and I felt Gemma at cost.ie gave me the most impartial advice based on my complicated circumstances.
Rather than feeling I was being told there was a simple "best " solution I was comfortable thinking that all options were being looked at.

I found Gemma very efficient and helpful. Gemma stayed in constant contact with us so we could come up with the best rate for our company needs.
I would truly recommend this process.

Gemma went above & beyond to assist me with changing energy providers. We had issues getting out of a totally unsuitable contract we were stuck in. Prompt, efficient, extremely knowledgeable & friendly service. We have a new suitable provider for our business in place now which is proving to be more cost efficient.
Have recommended Cost.ie to other business.

We are group of apartment owners and engaged Cost.ie to help lower our common area electricity costs. Gemma understood our needs and our electricity usage and negotiated a great deal with our current energy supplier, effectively halving our costs. We were very pleased with the outcome.

Experience was great. Very professional and would highly recommend Cost.ie.

Great company, made the whole process super easy from start to finish. Would definitely recommend to anyone looking for a pain free process.

Agreed a contract with them on 21st of July 2025 sent all information requested by the agent Within 24 hours repeatedly contacted agent as had no confirmation about new energy supplier. Finally had an email
Back in from agent 3rd of October saying she was out sick and couldn’t understand why the energy company had requested a deposit as she had never heard of it before. Complete waste of time. Better off directly dealing with electricity companies yourself.

Superb company. Ross made everything really simple for my company and was hassle-free, seamless, and required me to do very little.

Ross at Cost.ie went through all the options for our business electricity account.
He clearly explained the costs, rates and process and made the whole thing very stress free and simple.
Highly recommend this company.

Cost.ie made my switch a lot simpler. The whole process was clear and easy to follow, would recommend to anyone looking to reduce their costs.

Quick and easy process! It was very reliable and made my life a lot easier. Highly recommend this crowd.

I would highly recommend Cost.ie, as they offered me great advice on my electric supply and the lady I dealt with was most efficient and helpful.
Keep up the good work.

Casiya Ladd was so helpful and polite helping me with my account . I have only a positive review for your company

Contacted by Caiya from Cost.ie late last year with regard to renewing contract for electricity providers. Made it very easy and got me a good deal. Would use them again

Caiya at Cost.ie was so helpful. She helped get my commercial energy account.
She took all the hassle out of switching for me and set up the new account.
With the prices rising I am fixed in and she has been in contact to advise me of this since my initial switch. I highly recommend everyone to contact them.
