Those two grey cables for the heating go to that old Wylex fusebox - there is no way that can possibly be suitable, as it will be limited to 30A per way.
That Trianco boiler will require far more than 30A, and will draw the full load current for the whole time it is on - which could be hours.
The result will be the fusebox contacts overheating and melting, eventually the entire fusebox will be a total loss and will require replacement.
From the picture, the boiler looks to be about 1m tall (based on the size of the other items in the picture), which means it is at least a 9kW model, could be 11 or 12.
Cables look like a 2.5 and 6mm, which presumably would be one for the boiler and one for the small heater.
6mm would just about be permitted if the heater is a 9kW, and the cables are surface mounted (or hanging in free air). If the heater is larger, the cable is too small.
Either way, that fusebox is NOT suitable for the boiler.
