Cahill Renewables

The team at Cahill were extremely professional, from first contact through to quote and installation. No pressure selling, offered advice where our requirements or expectations may have been unrealistic but never once forced us into any decisions. We had a seedless installation with the solar panel installers timed to complete as the hardware installation began. Discovered that we had a problem caused by UK power networks, Cahill handled that and had the UKPN in to make the required repairs then came back to complete the job. Everyone hopes for a faultless system, but to us, the real quality of a company is when you do have a problem. Some of the kit failed, but a call to the team and they pulled out all the stops to get things fixed. Their after sales customer experience is exemplary, if only every company were as good. If you’re look for solar installation with batteries, you can’t really go wrong with the team at Cahill.

Cahill's arranged our Heat Pump central heating very professionally from the start. They took care of every detail, nothing was too much trouble. The team who came to do the installation were very good. As we are getting on in years and live in a small bungalow moving things in preparation could have been a problem, but, the team took care of everything, moving things and clearing up after themselves at each stage, we just provided the tea, coffee and biscuits. In three days the whole thing was finished and working. One of the main points we were pleased with was the way they ran the pipes under the house, so, no pipes running along skirting boards. All this for a very reasonable price. A very professional company.

Having decided to have solar panels and batteries installed Cahill Renewables were one of five companies we approached for a quote. Right from the start we were impressed with their response, their efficiency and willingness to listen to what we wanted and to answer all the questions we had. The quote we received was competitive and having agreed a date and timescale for the work it all went ahead as planned. All of the guys who came on site were polite, considerate, careful and professional. They worked extremely well as a team to ensure the job was completed in a timely manner and kept the site clean and tidy. We enquired about having some additional electrical work done linked to the solar installation and this was scheduled to fit in with the existing work whilst they were on site. We have no hesitation in giving Cahill Renewables 5 stars in all aspects of their work and would certainly recommend them to others. A great team in all respects.

Had a very keen quote from Cahill , the panels inverter and battery were all from top rate manufacturers , Every stage of the installation was carried out with no fuss and all the trades done an excellent job, We are very happy and our solar system is generating all the power we need with some to feed back on good days

I considered quotations from six providers before choosing Cahill. All communications were professional. We set a date and Cahill delivered on time. They said they could install in one day and they did it. The two roofers were very experienced as were the two electricians. The commissioning was done the next day. They were fexible and provided good advice on number of panels and optimizers. Very satisfied.

I am an avid Which? user and for a project like this, where I had little knowledge at the outset, I was only prepared to use a Which? Trusted Trader. I received 3 quotes form suppliers in the South East and selected Cahill Renewables, based on their professional and helpful approach... they don't employ sales people so their business is dependent on recommendations and they are a Which? Trusted Trader with 5+ reviews. From start to finish they did an excellent job, they were polite, professional and helpful , keeping me informed on every stage of the process... I can honestly say that they exceeded my expectations! I particularly liked that they came up with suggestions to save money rather than to just add cost. I have no hesitation in recommending this company to others. and it feels really good to be generating our own electricity from the sun!

Couldn't ask for a better experience. Right from planning/designing the system Cahills showed they knew what they were doing. They gave open and honest advice, listened to our expectations and told us what we could get. We asked for some changes to the proposal and a discussion adapted those to the final design which was installed in a single day - panels, inverter, and batteries. The on-site staff were a great bunch, efficient and friendly, and before long the system was running our whole house. Very pleased with the whole deal.

My son had Cahill install a similar system and was very pleased with the quality of the work and the attitude and enthusiasm of the whole team. Having recently had two chimneys removed this gave me a large roof area suitable for a reasonable PV array Cahill were helpful without being pushy Joss in the office was enthusiastic and knowledgable and supplied a detailed plan for my roof area. At no time was I put under pressure to buy although their quote was not the cheapest it was very competitive however I was impressed by their attention to detail and technical ability. They arranged for scaffolding to arrive on the day they were supposed to be here and completed all the work within their declared timeframe. From start to finish everyone was polite, helpful and dedicated to ensuring customer satisfaction. All in all great job from tradesmen to the Directors I can highly recommend this company for their can do attitude .

Cahill Renewables installed a large solar installation of 28 PVs and solar edge battery/inverter at my home. Initially recommended by a neighbour, they quickly drew up a draft design based on the google earth details of the house. They then arranged for an on-site survey which supported their initial design. At this stage they were able to finalise the estimate of cost to include the scaffolding and ground works. While not cheap, I considered the cost reasonable. During this stage of the process, they were very responsive to queries, and to carrying out (small) iterations of the specification. We agreed a date for installation. The day before installation their scaffolding contractors arrived, set up the scaffolding and the next day the installation team of 2 turned up. They worked solidly for two days, solving a number of unanticipated challenges along the way. They had a very professional 'can do' approach, and by the end of day 2 the installation was up and running. The following day some set-up was needed with the Solar Edge software, which the team at Cahilll did efficiently, making sure to communicate clearly what was happening. Two days later the scaffolding contractors returned to remove the scaffolding. Considering the size and complexity of the task, it was carried out with minimum of fuss, tidily and professionally. My electricity costs have dropped by over eighty percent in the three days since installation. Well done, Cahill team!

Our 6kW solar pv and battery system was installed by Cahill Renewables on 8th June 2023. Before deciding on Cahill, we sought many more than the recommended three quotes and by the time I spoke to Office Manager Joe I was getting thoroughly confused by the variations in proposed designs, components and costs. Joe’s patient explanations gave us confidence to choose theirs over similarly priced quotes, plus we wanted a local East Anglian company that specialised in all renewables, not just installing solar panels. Once the installation was done, on the promised date, they immediately provided the necessary MCS Certificate and DNO approval letter so we could export energy to the grid. In the first four weeks of operation, solar and battery power provided almost all our needs and we exported over 1 megawatt. Such is our confidence in Cahill Renewables that both our immediate neighbours are having their installations this week.

We were recommended Cahill Renewables by our friend and neighbour who had recently had some Solar Panels installed and we too would have no hesitation in recommending them. Our first introduction was with Joe who answered all our technical questions expertly with enthusiasm and no big sales pitch. The whole team was very approachable and knowledgable and the whole project from start to finish was smooth and stress free. We now look forward to generating and storing our own clean power.

We were recommended Cahill by a friend. The team have been so friendly and knowledgeable right from the start. Never a problem getting an answer on the phone and all our many questions answered throughout the process. The installation date was booked at our convenience and all times were kept to. The team arrived and completed the installation in a day, once installed we had a lesson in how to set up the app etc. Few hours later another call from the office to make sure all ok. We have no hesitation in recommending this company.

I chose Cahill after checking the "Which" reviews. From start to finish I have been completely satisfied with the communication, explanation and delivery of what was promised. The system was up and running in just over half a day, with no fuss and no mess. We have just had our first full day "off grid". The price was very good, especially in view of the overall quality. No hesitation in giving Cahill full marks.

We looked at several companies when considering our Solar installation. The key reason for us to select Cahill was the quality and manner of the interactions we had with Shane, the salesman who replied to our enquiry. At no stage were we put under any pressure, indeed He advised us when not to spend money as we wouldn't get the benefits from it. In terms of value, it was extremely competitive but extremely good quality, so the value was clear. Additionally, Cahill make a big thing about Ethical Sourcing and wanted to ensure that we had kit which was high quality and ethical. The quality of this interaction continued as we spoke to the directors and sub contractors who managed the install. They were very approachable and made good suggestions to improve the install. The sparkies were especially commendable and the quality of the install was superb. After sales service has also been superb and very responsive. We have already been delighted with the solar install and have saved significant amounts in just the first week. We would wholeheartedly recommend Cahill in every manner Great Integrity, attention to detail, quality, ethics, value and responsiveness Thank you!

Not necessarily the cheapest but but the whole process went without any hitches. Everything is working well. The electrician overcame problems routing the cabling to the inverter and battery so its all invisible.

It was very easy to deal with Cahill, from start to finish. Installation went smoothly on the chosen date. All trades knew what to do and the job was completed with the minimal of fuss

My conservatory makes it difficult to erect scaffolding on to get access to my west facing roof. Numerous solar companies had told me it wasnt possible to put scaffolding up without putting legs into the neighbouring property which was not an option for me. Cahill Renewables took a look at the space they had to work in, consulted their scaffolder who said they could put up the scaffolding without needing the neighbours garden and got it done with no problems. The rest of the install went ahead with no problems. The staff are friendly and have provided brilliant customer service to me. I would recommend them to my friends.

I chose Cahill after reviewing many review sites and I can honestly say their customer service and their installation teams are excellent. From the initial phone call with Joe in the office discussing the technicalities of the solar panels, the inverter and the battery system they addressed all my technical questions expertly. There was no big sales push, once I received the quote, they let me decide in my own time and I had to approach them to place the order! Coordination and communication from George were excellent from when the scaffold would be erected to when the engineers and roofers would arrive. On-site discussions with their electrical install team (Ken) were clear and they understood my requirements with respect to cables being in trunking and the colour of the external conduit etc. Their installation is exceptional, and their communication exceeded my expectations, and I would highly recommend them to anyone looking to install solar on their property.

We wanted a solar system and, after many false starts, were lucky enough to find Cahill Renewables. From the start they did everything they could to build us a system that matched our needs. They gave us an installation date but put the panels on the roof 2 weeks early. They then tried to fit the remainder of the system a week early. This did not happen, unfortunately, due to the electrician having an accident. They did come to us on the due date and installed, over two days, a brilliant state of the arc system. It works better than we could have wished for. All the people we have dealt with at the company have treated us with care and consideration. These people really do care about their customers. We would not hesitate to use them again.

We would be very happy to recommend Cahill Renewables. They were extremely helpful in talking us through the options when we first enquired. Their communications were excellent throughout, and they did exactly what they said they would do when they said they would do it. All of our dealings with Cahill were good but Joe, the Office Manager, handled our questions with professionalism, patience and good humour.

I contacted Cahill Renewables, after reading some of the reviews about the company. After speaking to George the contracts manager about the fitting of Solar Panels, I found him to be extreamly helpful, and was not at all pushing to get a sale. He very worked out a price for the system that would suit my requirements, and an aggrement reached. The fitting team arrived on time, and the three team memnbers were all very polite, and helpful with advice when needed. Their work was neat, and tidy, and they really worked hard installing the equipment. I would certainly recommend Cahill Renewablesto others thinking of having Solar Panels fitted.

Cahill Renewables have been excellent at every step of this process. Their quote was competitive and transparent. They have ensured that each step has been communicated well; excellent customer service is clearly important to them. The installation has come in three steps: scaffolding first, then 2 days later the panels installed with the next day down to the electrician and connection. All these steps have been undertaken by prompt, efficient and friendly people. I would not hesitate to recommend Cahill Renewables

Very professional and transparent from first contact to last. The talked us through the whole process, kept us informed of the progress and were true to their word. All work carried out exactly to original quotation. No hidden costs. All staff were polite, tidy and hard working. Courtesy calls received at each stage of the process to be sure we knew what was happening and when.

I can absolutely thoroughly recommend Cahill Renewables for solar panels and battery storage. Not only were they competitive on the quote, but their communications were fantastic. They actively encouraged questions and queries and were incredibly helpful. All of the quotes were online via Google satellite and street view and that worked very well. Cahill were able to give me quite a quick install date, and on the day the fitters were very quick, professional, and courteous. The electrician in particular was very neat and explained the installed system very well and had me logged in within a few minutes. I am extremely happy with the installation, their follow up communication, and the performance of the system. Top-notch!
