T4 Sustainability Limited

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

I 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.

We 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.
