The Holicon team are a wealth and knowledge and Liam is extremely helpful, he guided me through the different EV chargers and explained all the pros and cons, the team came to install and were very neat and tidy, Liam also made the effort for an out of hours visit to walk me through the app due to my work hours. A great service and would highly recommend

When I started looking at getting a solar and battery system installed I did the usual online research and contacted several companies for a quote. The whole process can be very overwhelming and can get quite technical for those approaching it for the first time. This is where Holicon Energy stood out amongst the crowd as local family run business. They ensured they understood my solar energy needs before recommending a system and explaining why that would be a best fit for me. They still offered some variation on options which allowed me some flexibility to choose but I felt really comfortable with Dan’s approach to taking me through the options and explaining in a down to earth way the pros and cons of each. The install itself went very smoothly with the professional onsite team and I was up and running in no time. All paperwork was taken care of swiftly by Lois allowing to apply for my Export MPAN number in no time at all. If you are thinking about taking the step then give these guys a call as the whole experience for me has been positive from start to finish.

Having recently purchased a Hybrid Motor Vehicle and wanting to go one step further to becoming self sufficient I looked into adding Solar to my property. I Knew of a local Family (Holicon Energy Ltd) that were deeply invested in installing renewable energy in all aspects so I contacted them for a detailed explanation how it all worked and what would be the best application for myself. Liam came along to do a survey and explain to me my options in full and clear understanding and answered my questions. Once I had decided on my system, (3 different options given), I contacted the office and spoke with Lois who was prompt at getting all the necessary paperwork over to me so we could get the ball rolling. They were prompt at getting the materials and arriving on the Day that I asked for. Liam and Connor got stuck in to a couple of days hard work, Neat, Tidy and very polite couple of Guys who were very good at their jobs. They placed each item where I asked for them to be and was up and running at the end of day two. If anyone is unsure on this venture, I can highly recommend Family HOLICON ENERGY Ltd. Thankyou Lois, Dan, Liam and Connor, much appreciated.

7.2kW of PV with a Powerwall 3 and Gateway - all done very tidily in just under three days. Very friendly team and sorted the G99 very quickly. Paperwork for export also arrived very promptly. Roll on the sunshine. Thank you so much.

Holicon installed 8 solar panels, invertor, battery and EV charger on my property. It took them only 2 days to complete. I cannot fault the service I received from this company, very professional, informative and helpful. Nothing was too much trouble for this friendly and caring family run firm, would highly recommend them.

Thank you so much Holicon. From Dan coming to survey, to Liam and Conor who worked tirelessly in fitting our PV system. Their work was clean and efficient, and everything left as they found it. It was a pleasure dealing with the whole family.

I would highly recommend Holicon. If you're like me, you were probably fearful to know who to use to get Solar Panels installed. So many adverts pop into Social feeds but you never know how professional these companies would be and there are many scare stories out there of bad experiences. Holicon is a family owned business. They were an absolute pleasure to work with. Lois provided all the admin help I needed. Dan visited me to do a site survey and share a proposal detailing the layout for the panels, the install process, what to consider when sizing the battery, the payback timescale and the all-in costs for their installation. I felt very comfortable and had a high degree of trust. The installation process was completed by Liam and Connor. A couple of really lovely lads. They were very friendly and patiently answered all my questions. The work was executed surprisingly quickly, with neatness and professionalism. I couldn't be more impressed. A fantastic service from a fabulous family owned business. You're in safe hands for sure.

Excellent service. It was all perfect. Liam and Connor were very polite and efficient. There were unforseen problems which were not down to them but they were solved without fuss and we were kept fully appraised of progress. I happily recommend them.

Definitely worth using! As we didn’t know much about solar energy we initially had six different companies out to discuss designing and fitting a system, all of whom gave very different views on the situation. Only two companies designed a proper system to suit our needs, and we felt Holicon were the company to use. They were extremely helpful in discussing our requirements and were very accommodating with all the questions we kept asking! They installed the system neatly and efficiently and it was reassuring to know the people who came out to discuss and design the installation with you, were then the actual people who would fit it. We had a few settling in problems mostly with the software side from GivEnergy and as they couldn’t sort it straight away, we had Holicon round and they sorted it out for us whilst liaising with GivEnergy. Only thing would say is that I think you generally need more battery power that you think you need so we got Holicon to install another battery, and now our system is all working well and saving us a fair sum on our electric bill. It’s nearly a year since we had it all fitted and very pleased with the system Holicon installed.

Holicon provided an excellent service for the installation of solar panels and and battery storage for our village hall. From the start, they took the time to understand our needs and and provided a detailed proposal which helped us obtain our grant funding. Installation was very smooth and very tidy and several of our hall hirers commented on how friendly and professional they were. All the follow-up paperwork was completed efficiently and in a timely manner. I would have no hesitation in recommending them.

HOLICON were a pleasure to deal with, whole process was clearly explained and all my (many many) questions were fully answered. The installation was very smooth and neat carried out by a professional team, I work in a technical background (and I'm a stickler for detail) and I had complete confidence in the team, thier workmanship was excellent. I wouldn't hesitate to recommend HOLICON Energy to anyone considering a solar installation.

It gives me great pleasure to write this review of the installation of 24 solar panels and 9.5 kw battery system carried out by holicon From start to finish the contract was completed seamlessly from survey by Dan to fitting and commissioning by Liam and Connor expertly backed up on the clerical side of things by Lois all relevant applications guarantees and certificates expertly taken care of in fact the only thing we had to do was provide refreshments biscuits and pay the bill which was split into 3 easy stage payments The system works perfectly for our needs and was tailored specifically for our lifestyle We couldn’t be happier with our purchase from Holicon coupled with the fact they are a family run local business We are very grateful for your expertise and professionalism and couldn’t thank you enough for a totally stress free experience Many thanks Mr and Mrs Sayer

Top class solar energy and installation service. This is a family owned and run business that has done a great job for us installing a solar energy system in North Norfolk. Everyone has been friendly, efficient and very good at their respective jobs. They have made something that can look complex understandable and achievable. Very pleased with their work and highly recommended.

Holicon is a small family run company with a passion for greener energy. From our initial meeting with Dan to the installation of 14 solar panels and battery we have nothing but praise for them. Liam, Jake and Conor who did the installation arrived on time, were polite and courteous, worked hard and tidied up after themselves each day. Liams knowledge regarding solar power is outstanding and he answered any questions we had. All the paperwork we needed before and after the install was sent through quickly by Lois so a fantastic experience all round. We highly recommend them.

Holicon installed a 3.5kv system with battery and hot water diverter. The tradesmen were efficient extremely polite and knowledgeable. I chose a local family firm over a (cheaper) national company and I was thoroughly satisfied with all aspects of the installation. I also gained valuable information from Liam on which energy supplier would most suit my system. I cannot recommend them highly enough.

You can choose Holicon as your supplier with total confidence. We chose the company to supply and install our PV system. We had approached three other companies, those that appear on the frist page of a Google search, but they were all wholly unconvincing; lack of detail, long delivery dates, left a sense of concern behind when they visited. When Holicon were recommended to us by a friend who had them install his PV system, we gave them a call and Dan came to see us within a day or two. From the outset, there was a friendly approach, clarity of detail and an immediate sense of here's a company one can trust; a family business in which everyone has a role and shares an outcome-led commitment to their customers. Holicon proposed a solution that provided 30% more output than any of the others for very little extra cost and installed our PV system within less than three weeks. Laim and Connor worked hard, got the job done in two days and were diligent in tidying up. Liam is clearly Holicon's technical expert and is generous in sharing his knowledge. Now we're running on sunshine! I have no doubt that if you choose Holicon you will be delighted with the outcome.
