A toilet that runs constantly can waste more water than the rest of the house combined, quietly, day and night. A weak or double flush, water on the floor behind the pan, or a cistern that takes an age to refill are all common and all fixable, usually without replacing the whole toilet. LMB diagnoses the actual fault and fixes that, with a 5.0 record from 207 Google reviews behind the work.
The usual faults, and new installs
Constant running is nearly always the fill valve or the flush valve seal, both quick replacements. A weak flush can be a worn flush mechanism or a partial blockage in the pan. Water pooling behind the toilet usually points to the pan connector or the seal where it meets the soil pipe, the leak you want caught early before it reaches the floor below. Each has a clear cause, and the fix is the part that has failed, not a whole new suite.
Fitting a new toilet, whether a like-for-like swap or part of a bathroom refit, is standard work too, including the supply and waste connections so it is solid, sealed and not rocking.
