What wall fixings to use for a kitchen cupboard

[jrussuk]

Hi
I'm installing 2 kitchen wall units and would like some help with what fixings to use. The wall units are 600 x 900. The wall I'm fixing them to is brick but has been lined with plasterboard using "dot and dab". What type of fixings and screw size should I use.

Many thanks

Jason

70mm screw with suitable wall plug for brick, careful not to overtighten and distort the plasterboard.

Cheers size 10 or 12 screw?

Either, some say the bigger the better.
