Really helpful and made it easy for us to get a new energy contract sorted. Can be a little pushy with their expectations with getting documents sent to them.

Cold calling about utilities. We are Corporate TPS registered so no decent, credible business should be bothering us.

Couldn't have hoped for a better outcome

Renew & Sustain have helped source the most competitive energy rates for our 48 sites. They handled all of the switch over in a smooth fashion. All good so far, but might not have prompted me reaching to write a review, and then...............
.......on Wednesday PM we had reports of a smell of gas in one of our basements. Transco intervened swiftly, within the hour, but condemned the meter. Joe at Renew & Sustain was all over the situation, providing updates late PM, and early AM, resulting in a new meter installation before noon the next day (Thur). To complicate the matter we share the supply with a 'sub-let' in the building. Joe has also spoken with them.......worked out a separation of supply......and calmed a tense situation right down, resulting in our neighbouring business singing his praises too. Couldn't have hoped for a better outcome.

Great service

Dear Jay
We would like to say a big thank you and your team at Renew and Sustain for helping MT Print save money by sourcing a new energy contract for both our gas and electricity.
We were aware our current contract was coming to an end, but we hadn’t realised how much the charges would go up. We had no communication from our old supplier and we were shocked to find it quadrupled, going from £1200 to £3500 per month.
The biggest difference was the standing charge, which went from 14p to £38 per day.
After speaking to Jay, he took copies of our old and new energy bills, within hours a member of the quote department Callum was on the phone discussing cheaper tariffs.
You and your team were very experienced and efficient, saving us both time, money and stress by searching for the best provider so we can concentrate on the business.
We wouldn’t hesitate to use you guys in the future and would highly recommend you to friends, family, customers and anyone who has been in the same situation as us and needing to source cost effective energy.
Many thanks, Phil Harburn

Our experience with Renew & Sustain has been excellent, their team’s expertise and professionalism have worked well with Green Shield Group's inhouse technical and solar installation team.

Jay Savage, the Head of Sustainability, deserves special recognition. His knowledge and dedication have made implementing sustainable practices straightforward and effective. Jay's proactive and clear communication ensured everything ran smoothly.

First and foremost

First and foremost, their team is incredibly knowledgeable and passionate about energy. They took the time to understand my specific needs and provided tailored recommendations. Their customer service was fantastic resolving all our issues before even trying to sell us a contract. They are kind, fair and courteous taking all the time to listen and understand our company from top to bottom. They were successful in resolving our billing issues in 24 hours something which I had been on at for months. Then they successfully managed to save us a large chunk on our annual costs displaying every option available to us and not trying to force anything upon us. Jason, Gary and Callum all worked together seamlessly, keeping me in the loop throughout the whole process.



I feel safe that my business energy is now in good hands with a fantastic team. Not like any of the other brokers I have previously dealt with who got me into this situation in the first place. It’s clear that customer satisfaction is a top priority for them. The little welcome email from the director Danii is a great touch. They have exceeded all my expectations, and I am delighted with the results. I cannot recommend this company enough!

Excellent and clear service

We had several quotes from our existing broker and from Renew and Sustain. Julie and Callum set out by asking the appropriate questions and took charge of getting quotes. They beat our original broker by 10% for a green energy tarrif. They were excellent at keeping us updated and with best choices available. Much more so than we got from anyone else. Many thanks for your excellent customer service, the clarity of the process and outcome we hoped for.

Liars and frauds!

I was cold called by one of their staff who then passed me to a gentleman called Gary. I was given a "renewal" from my current supplier verbally over the phone (this turned out to be complete lies) which was far higher than what I was paying at the time. However, don't worry Andy, I know I can beat that price by going to market and dealing with suppliers on your behalf. A few hours go by and Gary came back to me giving it the "Great news, I've managed to beat the renewal from YU with a company called Smartest Energy. All sounded good so I signed up. As we get closer to the start date they then call me up and advise YU came back with a more competitive offer and they'd like to renew me back to them. I asked would I be penalised from from Smartest and they said no. Great, lets sign the renewal then. We are now months down the line and I'm being chased from Smartest and some debt recovery company and the YU renewal isn't actually the rates I agreed. Terrible service from a terrible company. I'm, currently dealing with the Ombudsman and would encourage anyone else who has fell foul to these crooks to do the same.

Hi andy, thank you for getting in touch. We take these matters very seriously. However upon searching our customer database we have no record of "Andy Jones". We have also requested information through trustpilots flagging policy and you have failed to provide trustpilot with any evidence to support your claim.

Renew and Sustain

We worked with Renew and Sustain and they were absolutely grateful in helping us out. We had some issues that could have seen our business going bust but Joe the sales director was more than happy to help us out and saved our business. The team also got us a £12,500 refund back which we are now going to invest into the club. Very grateful for Renew and Sustain would highly recommend.

The team at Renew and Sustain were very helpful throughout the process of reviewing our energy costs.
We were experiencing some issues with meter readings, but the team were on hand to deal with suppliers directly to resolve.

Renew and Sustain are a breathe of fresh air as Brokers

Renew and Sustain have been a breathe of fresh air as brokers. They are very helpful and listened to our needs and what our concerns were.

They went to the market and get really good prices from a difficult market.

I would like to commend Zee on how helpful and how good he is at his job. He did not mind dealing with any queries we had and could not do enough to support us. He is a credit to the company.

I would also like to thank Wez (Gary) for his time and patience with us during our busy time.

They've transformed our perception of energy brokers.

I don't normally leave reviews but felt compelled to leave one this time.

Switching our business energy provider had always been a task we dreaded until we discovered Guy and Joe at Renew & Sustain. From our very first interaction, they took charge, making what seemed a daunting process incredibly straightforward.

Our account manager, Guy, was always a call or email away, promptly addressing any queries we raised. He was patient and understanding of our needs, something that was quite refreshing.

Joe, the pricing specialist, did a great job. His unrivaled expertise and fastidious approach culminated in him fetching us the most competitive pricing in the market. He was transparent about all the costs, ensuring there were no hidden charges—something we've unfortunately encountered with previous brokers.

This professional approach from both Guy and Joe prompted us to secure our contract with Renew and Sustain. They provide a superior level of customer service. As a business, we cannot recommend them enough. They've honestly transformed our perception of energy brokers.

I definitely do not recommend this company

We got contacted by Martin at Renew and Sustain last year about a smartest energy contract and was told it was a holding contract and if the rates drop we are free to sign with another supplier. Long story short it was lie and we are stuck in it. I spoke to Joe at Renew and sustain in August and opened a complaint. Joe phoned me and said Martin had been sacked because he had done this to other customers. He then denied saying it. He said he would speak to smartest. When it come to the contract about to start he still hadn't notified them. So i emailed smartest directly and opened a complaint. In my experience i would never recommend this company to anyone. I have a recording of the broker admitting he told me it was a holding contract. You would have had a customer for life if you hadn't tried to hold on to the miss sold contract. They also then sent a company called Pre Action to chase for lost commission's even though the contract hadn't even started at that point. This has cost our business £70,000 and is forcing us to retire a year early.

The complaint was taken so seriously that you didn't even open one with Smartest energy, it was taken so serious that Joe lied and denied what he told me on the phone. It was took so serious that even when i got Martin on a recorded call admitting what he done you still told smartest the contract was valid. Then in the middle of all that you had a company chasing us for the commission you would lose. If you had pulled the contract when i contacted you in August we would have quite happily signed a new one with you.
I don't know how you sleep at night.

Reply from Renew and Sustain

Thank you very much for your feedback it is very important to us. Your complaint is something we take very seriously. This sale was thoroughly investigated and all the evidence you provided was shared with both the supplier and 3rd party to ensure everything was delivered as promised. Our sales process and compliance process is very robust to ensure situations like this do not happen. First it was investigated internally and no error was found, it was then investigated by the energy supplier and again no error was found, finally it was investigated by a 3rd party alternative dispute resolution provider and was found to be 100% compliant. However we appreciate at the time your contract was booked in with the supplier the rates where high nearly a year before you opened your complaint.

Despite all the above we still went above and beyond managing to get the supplier to offer you reduced unit rates in the same agreement which you refused. This would have saved you a very large sum.

I am disappointed that despite everything we did to try and resolve this no progress was made.

We appreciate your feedback and sharing your experience with us. We will continue to work on this in the background and would appreciate the ability to keep the conversation open. Please do not hesitate to contact us by telephone or email info@renewandsustain.co.uk.
