1I contacted T4 in november 22 and left a message. No call back. Contacted them again a few times (should have seen the signs) and eventually got through to John Beardsmore. He is very knowledgeable and polite. Discussed with him my needs and said he would make an appointment. A few calls and messages later (nothing). Finally got him in mid Feb with numerous apologies due to workload. He visited in March and we discussed my needs. John said he would put a quote together. Again numerous calls and messages (nothing). Managed to get him again in late April - again apologies due to workload and excuses for no quote. I politely mentioned its dragging on - again apologies and promises something would be put together soon. Again nothing. Come June 23 and a few messages to say something would be put together in the next days - guess what nothing. Sadly a total waste of time and effort since I explained from the off I wanted a system installing ASAP. So 8 months wasted. Sure way to lose customers.

1Ed is rude and if what you say doesn't suit him then he will call you pointless

5I have had a working relationship with T4 since around 2010 for items including solar thermal overhaul, log boiler overhaul and maintenance and heating and hot water maintenance. I have always been very happy with their level of service and conscientiousness in everything they do. They are very dependable and I'm proud to call them my go-to partner for renewable heat.

5We are very happy with the PV installation we have received from Ed and the team. T4 were able to accommodate a design and install at relatively short notice so that we could take advantage of suitable scaffolding already in place for external wall insulation work. The survey was thorough and the quote was detailed and easy to understand. The team were able to work along side the other company working on the external insulation. It turned out my electrical earth bonding wasn't up to scratch but this was rectified really well. Even with this slight setback they were able complete the install in time for the scaffolding to come down on time. They even repositioned my TV areal to avoid birds messing on the panels. The install was finished neatly and no mess was left. The system was explained to me at the end and they help provided all the details I needed to apply for the Octopus Outgoing tariff. The system has been working well all summer and I have received my first payment back from Octopus Outgoing. Thank you T4 and I will be back in touch in a few years If I can save some pennies to add on battery storage.

5Excellent service. Dealt with what was a difficult installation due to our requirement as well the nature of our house and garage, and produced a aesthetically pleasing and effective result.

5I have used this company now for a number of years to service and maintain my biomass boiler. They have always attended promptly and on the day the said they would or let me know if there was a problem phoned me in person to explain and arrange to come the next day. They provide a professional service and respond to any request quickly with a message or in person. I have no hesitation in recommending this company to anyone needing their heating system repairing or replacing.

5T4 installed a set of photovoltaic panels on our roof. It was a far from straightforward job and took longer than expected, but Paul and the team did a great job and were helpful and friendly with good communication throughout.

5T4 Sustainability recently fitted our Solar Thermal system through the Green Homes Grant, they were fantastic. Simon and the team were professional, prompt, and did everything they could to fulfil our needs after a previous supplier dropped out. We can not thank them all enough.
