In our previous home we were supplied with LPG from Flogas, which proved to be cheaper than Calor. I have just asked them if they could supply our home. Of course we would need our own tank being installed to do this and isolation from the Calor mains supply if authorised from Calor.
We also asked whether Flogas could supplying the village subject to price, they said they would let us know if they were willing to tender and discus replacing Calor. This solution is probably a none starter irrespective of their feedback as many will not want to change from Calor regardless of price.
Flogas: Is part of FTSE 100—listed, DCC Energy, we provide tailored, reliable and affordable energy solutions to domestic and business customers the length and breadth of the UK, and have sister companies that supply homes and businesses across Ireland, France, the Netherlands, Sweden and Norway
The other point irrespective of the above is that the current tanks need to be toned down, the houses facing them do not need to see the eyesore of white tanks. I am sure Calor camouflage them Green if asked.
