Honeycomb plasterboard wall(no batton) how do I fit wall units and extracter hood?

If you have a plasterboard partition to fix wall unit brackets and extractor hood you can use Hollow Wall Anchors for plasterboard walls. They are different types. Each of them can hold from 20 to 40kg. To fit Anchors you need a special tool: Rawlplug Setting tool. Hope this helps. You are welcome

Good answer from Rolandas, ( GRIPIT) sells a similar fixing for hollow plasterboard walls and in the past, I have used these in conjunction with a cabinet hanging rail as you can add more fixings, please see below the link provided. Hope this is of some help. http://www.abbeykitchens.co.uk/carcase-support-systems/wall-fixings/cabinet-hanging-rail-150kg-loading-capacity-2m-long-steel/prod_2482.html

I would fit patresses to the wall with pink grip and screw them to the wall using plasterboard fixings, that way the cupboards are load bearing and won’t fall off
