How to Access Concealed Cistern ?

[John Bol]

Hello, my toilet has started to trickle constantly after flushing. I expect it to be a fairly simple repair however i can't get access.
As shown in the pictures the Cistern is completely tiled in, with apparently no easy access "hatch". I was hoping the top tile would lift off easily after removing silicon, but its solid.



Do i need to just rip off the top tile with a chisel or something, and then re grout it back on afterwards?
Or am i missing a much easier option
Any help greatly appreciated!

Thanks

The tile on the left, the vertical one, rests on top of the one you are attempting to remove. You need to cut through the grout/sealant there too.
