Backwater Artists Group

We are an artists studios in the heart of Cork City who are constantly looking for ways to reduce energy costs. We have worked with Finbarr for a number years and he has always provided us with an excellent service. He is professional, extremely helpful and he has extensive knowledge of the energy market. Every year he provides advice on the most cost effective energy packages on the market and saves us time and money, as a result.

The first year we worked with him he provided advice on how to reduce our PSO levy which now saves us over €1,000 a year on our energy spend. This year he has provided us with advice on how to reduce energy costs during the COVID 19 pandemic. I could not recommend Finbarr and Quantum Energy enough.

Apache Pizza, Cork

We have been with Finbarr for several years, during which time we have received excellent and timely service and advice on our gas and electricity contracts. We feel confident that they are looking after our best interests and we are happy to leave it to them to get the best energy deal for our business.

Castle Capital

As a financial broker we are always looking for strategic ways to be more cost efficient. Not just for our clients but for our business as well. Shopping around is great if you have the time but we’d rather stick with a known, trusted provider. Since we’ve been working with Quantum Energy to reduce our energy costs we’ve also had no problem referring our clients to Finbarr and the team. Initial service is great but what works best for us is the aftercare check-in to make sure everything is running smoothly and costings are as initially discussed. We work with clients who want an above and beyond service.

We’re no different and we know we can rely on Quantum Energy for that.

Ballyphehane Community Centre

As a large community centre facility, we have constant usage of various meeting rooms, sports hall and offices. Therefore our energy spend is substantial. This usage & spend is under regular review by Finbarr, with practical advice on usage and opportunities for savings explored on a regular basis.

We are confident that Finbarr & Quantum Energy are looking after our best interests and we are happy to leave it to them to monitor the market on our behalf and to provide us with a comprehensive summary of what is available, with their recommendations on trends and cost-effective options.

We had heard reports from the media regarding the recommendation that households and business should review there energy bills every year … We were always nervous moving energy company as we had always been with the ESB.

Finbarr came to us highly recommend from another parish …He explained and completed everything from start to finish and saved us over 35% on our gas alone ..
We couldn’t recommend Finbarr and Quantum Energy enough ! Trustworthy and efficient.

O’Donovan’s Hotel

I must have had over 10 different companies trying to get my business over the years ..Some very pushy who contacted me on a daily basis, and other who were rather rude, but Quantum Energy was by far the most polite, professional and not at all pushy.

I would like to thank Finbarr in particular for his patience in sorting out my electricity contract, it was greatly appreciated. He had a professional attitude and nice manners, a credit to the company.

Many thanks!

Ardenza Childcare Ltd.

I have found the service offered by Quantum Energy to be extremely professional and efficient. By simply providing them with a Letter of Authority and copies of our most recent bills, they were able to obtain details of our current contracts and then save us in the region of 25% on our gas and electricity contracts.

Kind Regards

Clare Waste & Recycling Ltd.

I cannot recommend Finbarr and quantum Energy enough. He has more than gone the extra mile, and has the clout and knowledge to fight these large companies and get the best for every size of business. If you have not yet used Finbarr services I recommend that you do. I have, and saved 15% off my utility bills this year, as did the company I work the accounts for.

Westport Adventure Park

We run an adventure centre in Westport Co Mayo, with a lot of onsite accommodation.

Padraig from Quantum Energy reviewed all our bills separately and selected different deals for each account, going into great detail to find savings. Recently Padraig entered our guest lodges for the Supply Suspension Scheme due to the Covid 19 lockdown, which was very helpful.

We were impressed with his attention to detail and willingness to help his energy customers.
