I would highly recommend Hero Renewables. — Mr Bright | Cheshire ( Google Review )We contacted a number of different suppliers and settled on Hero Renewables because they explained the process etc better than others and were very competitive on price. The process was quick and easy for us and they kept us up to date on progress at all stages. It was delivered on budget and on time and we are very happy with the panels and the performance of the system. I would highly recommend Hero Renewables.
I would recommend this company. — Mrs Stewart | South Wales ( Google Review )From the salesman right through to the fitter, they have all been friendly, helpful and approachable. Dates and times were kept unless, understandably, the weather prevented it. The installation was completed in the time scale quoted, despite the awful weather. The stage payments were made easy to pay and work done very quickly after each payment. I would recommend this company.
Their customer service is very friendly — Mr Abbott | Cheshire ( Google Review )“We've had a ground source heating system from Hero Renewables for a few years now. They were outstanding in fitting the system, extremely helpful and attentive in meeting our requirements. In the time since the system was fitted it has been very efficient and reliable, with the few minor problems that we have encounter (plus annual servicing) all dealt with very swiftly. Their customer service is very friendly, and they will help with any queries you have about going green.”
The team sent were fast and efficient. — Mrs Philip | Glasgow ( Google Review )Hero installed a solar system into my new roof. The team sent were fast and efficient. They also removed waste and left the area clean and tidy. They did have a delay with the batteries but that was down to their supplier running out and a need to source a new supplier.
I found their knowledge and advise to be very helpful — Mr Till | Oxford ( YouGen Review )Hero Renewables first contacted at Newbury show in 2016 where I found their knowledge and advise to be very helpful for me in getting more from my existing Solar installation. It was no surprise then that I eventually placed my Order for their upgrade recommendation and installed additional Solar Panels and Solar-edge Inverters, this done very professionally and is still working great. I additionally also had battery storage added in the form of a Tesla Powerall 2 and can now benefit from using this in the evenings to keep my electricity costs low
all Hero's staff took care to explain best practice in use — Mr Nelson | Oswaldkirk ( YouGen Review )Hero were one of the few installers who offered to combine different technologies in the most effective way - in our case ground source heat with solar PV. Also one of the few installers who had a solar PV solution which would meet planning requirements within an Area of Outstanding Natural Beauty. The technical sales manager took the time to talk us through the options and helped us understand the technology. Over several visits, and during the install, all Hero's staff took care to explain best practice in use. We had some initial teething troubles associated with getting the control interfaces co-ordinated and calibrated, but now that has settled down, its performing better than expected.
Hero are a great firm. — Mr Whitehead | Chesterfield ( YouGen Review )Hero are a great firm. Tom Mastin who did our installation was excellent and would recommend them. i rate them 5 stars in all classes (price, advice, installation, fit arrangement etc.
Their installation was faultless and the system has worked well ever since — Mr Graebe | Cirencester ( YouGen Review )We were very happy with Hero Renewables, in respect of their sales and recommendation. Their installation was faultless and the system has worked well ever since - delivering, if anything, more than was promised. We haven’t had any reason to contact them since the installation.
Work done on schedule. — Mr Sterry | Tewkesbury ( YouGen Review )I went with Hero after I received a prompt response following an Exhibition Enquiry. Their customer service was very good. All questions answered clearly and promptly. Work done on schedule. Competent and interested contractors, job well done and follow up checks on completion. Hero explained my options to me through written description and demonstration by installer. further instructions by phone. So far it's generating as much electricity as expected.
Excellent value for money — Mr Grundey | Shropshire ( YouGen Review )Amazing customer service - Hero went through the process in a clear way that was easy to understand with all different options explained. Excellent value for money - the house is so warm and it is cheap to run too!
We are very happy with the system installed — Mrs Clarke | Tywyn, Wales ( YouGen Review )We encountered Hero Renewables at the National Homebuilding and Renovating Show at the NEC in Birmingham where they were the only company exhibiting the Tesla storage battery. Their customer service was very good indeed. Tom Mastin spent a considerable amount of time and effort explaining the system and his talk was followed up by a site visit to agree where the various components could be placed to ensure the best and most convenient results from the system. In terms of value for money, we had some idea of the cost of a PV system without the Tesla battery storage having already had a quote some time ago from a local company and found the quote from Hero to be competitive.We are very happy with the system installed and, with some guidance from Hero, have learnt how to use the system to get best results.
I would use Hero again for any work I have done in future. — Mr Mackenzie | Warwick ( YouGen Review )I chose Hero because they provided the best response when I contacted a few installers. I was also really impressed as they provided a good follow up service where we discussed various options when selecting the right system for me. The ASHP and solar systems are both working well and delivering benefits. I would use Hero again for any work I have done in future.
Hero had a good sensible attitude and competitive prices. — Mrs Robins | Hertfordshire ( YouGen Review )Hero had a good sensible attitude and competitive prices. Their customer services were very responsive and the system is performing as expected, proving to be good value for money so far.
professional and careful approach — Mr Currah | Thorpe ( YouGen Review )Tom Mastin took a professional and careful approach to the installation and provided excellent service throughout. He explained to me my options though discussing with us what our requirements would be. So far it has been great value for money although the output is slightly lower than expected.
All in all very happy with the service received. — Mr Oberon | Carmarthenshire ( YouGen Review )From the salesman to the fitter I found them all very polite and helpful. All the questions, and I had a lot, were answered informatively. Appointment times were kept and the installation was completed in the time allowed despite the awful weather. Payments were done in stages which suited my budget and I was always reminded in good time of payments due with the work being done very quickly after the payment was made. All in all very happy with the service received.
I would highly recommend Hero Renewables. — Mr Ivy | Cheshire ( YouGen Review )We contacted a number of different suppliers and settled on Hero Renewables because they explained the process etc better than others and were very competitive on price. The process was quick and easy for us and they kept us up to date on progress at all stages. It was delivered on budget and on time and we are very happy with the panels and the performance of the system. I would highly recommend Hero Renewables.
I was very impressed with the knowledge and honesty of their staff prior to installation. — Anonymous Reviewer | Cheshire ( YouGen Review )I selected Hero through the approved installer scheme, selected one of the more local options. Hero could do both the Heat Pump and the solar and offered a comprehensive solution. I was very impressed with the knowledge and honesty of their staff prior to installation. Customer service around the time of installation was good. They found a number of issues with the existing plumbing and rectified those as part of the installation.We discussed the different options available for heat pumps and the different ground loop options and considerations. Very reasonable in terms of value for money, especially as we wanted the work to be high quality and so didn't necessarily go with the lowest price. We've been able to 'set and forget', as the house maintains warmth through the year and works particularly well with the underfloor heating (installed separately later by another firm).
Excellent customer service and also very efficient. — Anonymous Reviewer | Cheshire ( YouGen Review )I heard about Hero through their good reputation and saw them at a professional show room. Excellent customer service and also very efficient. Been great value for money so far and no issues have arisen.
responded well and quickly to my enquiries — Anonymous Reviewer | Warwickshire ( YouGen Review )I chose Hero as they responded well and quickly to my enquiries with both written and verbal explanations. So far system is living up to what I expected and is proving good value.
Price was fairly reasonable and their customer service was excellent. — Anonymous Reviewer | Hertfordshire ( YouGen Review )Price was fairly reasonable and their customer service was excellent. The person who came round explained my choices clearly and so far it's producing electricity well and I'm benefiting from the Feed-in-Tariff. They’re going to check on it again in 12 months.
Hero were extremely good — Anonymous Reviewer | Lancashire ( YouGen Review )Hero were extremely good – very prompt - we needed to move quickly because of Feed-in-Tariff change deadline and they did so. They acted promptly, efficient when they were here did the job faster than expected. I've experienced no problems so far.
personable and knowledgeable — Mrs Springett | Berkshire ( YouGen Review )The two lads that installed the system were personable and knowledgeable, they certainly put up with all my questions with a smile. While connecting up my battery to my panels they were happy to have a look at a problem I had with the panels (another company had installed them) and solved it, giving me 25% more power! Again, unlike my panel installer they are keen to support the solaredge monitoring website for my installation and handle any alerts raised.
Easy to contact team — Mr Millier | Lancashire ( YouGen Review )Good knowledge on product offering, I hadn’t realised that they installed other renewable technologies but would have been happy to have used them for our air source install as well. Easy to contact team and followed up installed with initial support.
Overall I'am impressed with the system — Mr Ammon | Milton Keynes, Buckinghamshire ( Google Review )I had my solar panels and Tesla battery storage fitted in 2017, initially the inverter was not working , it took a while for a replacement to be installed , when the system started working I Used the App to monitor the output. The system has been working now for two and a half years(April-2020) , no maintenance required , the 5KW system generates 45KWH + per day-from April to September, and performance declines over the winter , most days the system feeds power into the battery which can be used after work, there are only a few days a year ,when the weather is dull and overcast and no power is generated. Overall I am impressed with the system and glad I invested the money in an environmentally friendly way .
I'm more than pleased with the service I have had from Hero. — Mrs Neville | Thornton, Leicestershire ( Google Review )I'm more than pleased with the service I have had from Hero. They have been very helpful throughout. I have never had solar before and they advised me on what I needed and more unusually what I didn't need. They never tried to sell me anything other than my requirements. It was a slightly tricky fix because I have a metal roof but it looks fine and is very secure. They have also been helpful in providing documents to Eon for my tariffs. Eon it has to be said couldn't have been more awkward but Hero have helped me negotiate this. Thank you very much Hero
customer service was very good — Mr McClennon | Llandinam ( YouGen Review )I chose the installer as they were Tesla-approved, which I felt made them stand out. Their customer service was very good and so far I've found the PV great value, working exactly as intended.
Would highly recommend — Mrs Rhodes | Sandbach, Cheshire ( Google Review )We've had the solar panels with the immersun for nearly 4 years now and we are still very pleased with the system and the way it heats up the water in the hot water tank. The initial installation was completed as expected and the workmen very polite and tidy. The follow up checks from the company are timely and unobtrusive. Would highly recommend
Fast efficient installation — Mr Nasar | Stoke-On-Trent ( Google Reviews )I had solar panels installed 2 years ago and no issues all is well. Fast efficient installation from start to finish. The panels look great and generating electricity as I was told.
I can confidently recommend you will get a first class system — Mrs Downton | Oxford ( Google Reviews )"I have had two solar installations and a ground source heating system installed by Hero. I'm delighted with the outcomes on all three installations. In particular I have had total confidence in their engineers who have all been stars. Totally professional - really good at explaining thinks, courteous and friendly. If you are thinking of (and I highly recommend you do; its great to feel you are contributing to a greener environment!) installing either solar or ground source, I can confidently recommend you will get a first class system." "Their customer communication could be upgraded a bit, though they have improved over the two years I have dealt with them. I'd suggest at the outset of any project, you ask for a point person and a project plan. But do use them, their engineering work and understanding of the systems are first rate."
Great company who installed a solar system for me — Mr Donald | Greater Manchester ( Google Reviews )Great company who installed a solar system for me a few years back. I would have no hesitation in recommending Hero as they did a good job.
We have no hesitation recommending Hero Renewables — Mrs Mooney | Chesterfield ( Google Review )"We are extremely satisfied with the installation of our solar panels. The installers worked quickly and efficiently to complete the work. We have no hesitation recommending Hero Renewables and we actually chose this company based on the recommendation of a family friend. Well done Hero Renewables."
helpful staff — Mrs Willard | Crewe, Cheshire ( Google Review )"Hi, Good service helpful staff no issues that needed resolving"
They were true to their words — Mrs Jacobs | London, Greater London ( Google Review )"I first came in contact with Hero Renewables at Grand Design exhibition. I just was enquiring about Solar Panels. I was surprised to find out how affordable it was. Though I did some research beforehand, I did not realise how affordable having these installed. Hero Renewables first did an assessment and recommendation on their 1st visit and then gave me a price. They were true to their words - it was not expensive. Once solar panels completed - they sent me an app to download - you can see the amount of energy and What a difference it makes to my electric bill which I elected.A satisfied customer."
