Booster Pump Replacement

I'm looking for a quote to remove and install a new booster pump in my house in Kimmage. The current pump is a Walrus TQ400 - it is not running well so I want to replace it with a DAB Esybox Mini 3. I have already sourced this. The pump is used to boost water pressure in the taps / toilets / upstairs shower in the house. It's located in the bathroom on the second floor currently. We have a hot water cylinder and cold water storage in the attic of the house.
