Optic Realm Ltd

I moved into my flat with my partner in 2019. Optic realms were still finishing to build the other courts and we were told we had a 1-year warranty contract before handing it over to ISHA which is our housing association. Since day one we had many problems with the heating system and we still do ( as well as the other tenants in the other courts). We were at first told we would not pay any heating then they suddenly sent us a huge bill and we are still disputing the costs as they seem outrageous compared to most London energy suppliers. Fast forward to December 2021 all the other tenants in the other blocks are also experiencing the same issue with high hot water/gas bills and Optic realms keep sending us handmade spreadsheets with figures that I could make up if I wanted to as well since they are not based on meter reading or real actual comparisons with other energy suppliers such as neon, British gas to name a few.
This issue remains unresolved!

Personally many things went wrong with the flat, but Im just a few things of main concern: the heating stopped working after they replaced the pump. Optic realms refused to fix it as our 1-year warranty with them was over. it wasnt until a few weeks ago that I found out other tenants in the blocks managed by Optic realms had an issue with shower water pressure resulting in drastic changes in temperature ( which I had previously escalated to them and kept fobbing me off ) and so I tried to ask for the same plumber that helped us when they were still managing our block. To my surprise, they said yes ( they are building another block near us thats why ). The plumber came fixed the issue with pressure then I asked him to have a look at the pump for the heating. He said these pumps are not very good cause they fail if not used often, hes had to replace them in many other flats. He checked my radiators he said everything was fine, put an old pump that was at least functioning, and now we have heating after over 1 year.

2 days after the plumbers visit I noticed one of the radiators isnt working and its the same that wasnt working in 2020 when we were still under contract. I reported it and they said it was fine, but of course, after that, the heating pump broke so I never got to test it again till now.
I asked Optic realm if the plumber was over to come and fix it since it was broken since our contract with them was still in place and Olivia from Optic realms said no, I should call my housing association and then went on to say she knows they are rubbish but they dont manage us.
How professional and kind of her !!!!!
There is more, but I want to cut it short. Optic Realms are not professional and dont really care about their tenants they build luxury flats and care only to make a profit from them.

Find a better contractor !
