our shower has a water pump which has been installed for just over a year at the moment the shower is working fine but there is a noise that sounds like the pump is struggling or it is getting blocked(limescale) maybe?any help would be much appreciated.

If only in for a year it is probably still under guanantee. Whoever installed it should know. If not a supplier who stocks it will know.
A pump will make noise when the shower is on. They usually are run off mains supply so lime scale should not be involved. Long use for a shower could cause it to struggle. Depends on its abilities (Quality) to begin with. Limit showering time to 10 mins to see if unusual noise stops.
