I have just newly moved in to a new house and the current shower doesn't seem to have enough pressure in it and you seem to have to be right under neath it to get any coverage.

Is there anything that I can do to boost the pressure so the water comes out faster and a more higher volume.?

Remove the Shower head and turn on the water see if there is a good stream, if so clean the Shower head, and check if there is a restrictor installed inside the shower head, if it is remove it, and install the shower head you will be OK.
If there is a poor stream with the head removed, then there may be debris inside the faucet you will need to remove the cartridge to flush the valve or replace the cartridge, good luck.
