The plug needs to be slightly longer than the screw and I would use brown plugs and No 8 x 1 1/2" or No 8 x 2"

Thanks. I have the screws but need to buy some longer plugs. Most of them are 1” long.

They'll be ok.

But the screws are 1 1/2” or 2”. If the plugs should be longer, I need new ones.

Buy screws to suit the plugs.

Drill the correct depth/ size hole for the plug and screw you are going to use, insert rawlplug, then tap rawlplug in to hole until it’s just inside the hole, ( you can slightly screw in the screw or use the head of the screw to knock the plug in) you don’t need to hammer it in just a gentle tap

Thanks. Good vid here that covers the length of screw and what plugs to use.

Only 18 minutes long, there's a separate video for different wall types.

I have hundreds of screws all different types and sizes. No problem there but recommended length is 40-50mm and I don’t have that length in plugs.

Recommended by who? Length of plug plus thickness of bracket equals the right size screw.

It doesn't matter if the screw is a little longer than the plug you intend to use , as long as the hole drilled is deep enough for the screw

What's more important is using the right width screw for the colour of the plug 

Red plugs with 8 x 1.25" or 8 x 1.5" will be fine

The recommended screw length is the amount needed to splay the rawlplug in the wall which then creates the friction to hold things in place. The recommendations almost certainly assume minimal thickness of item being fixed so as Norman_Castle has said this needs to be factored in i.e. if the bracket means 10mm of screw will be out of the wall use a screw 10mm longer.

But in reality as long as the screw is long enough and the right thickness you will be fine. If the screws are too short you could have major problems if too long so long as the tip has somewhere to go (i.e. the hole drilled isn’t the bare minimum) you'll be fine. When I was first a homeowner I had no stock of fixings so bought the 'right' ones as I needed them, now I have a good stock I can almost always pick out something that will do the job, none of my fixings have failed (yet). I use red or brown rawlplugs for (almost) everything so have bought these in bulk, buying quality options for both (fischer and rawl IIRC)

Drill an accurate 7mm hole. use brown wall plugs,  match them with 50mm 8 (gauge)  screws and you will have a nice secure bracket to brick wall fixing.

8 x 1 1/2” (40mm) I think would do with either the red or brown plugs I have. The tip of the screw is just proud of the plug end.
An 8 x 2” (50mm) would have about 1cm out of the plug tip.
The bracket thickness adds 2mm.

Looking at the brackets you are using a 6mm drill bit with a red rawl plug drilled to a depth of about 35mm will well hold up anything you put on the shelves, you can cut a rawl plug down & push into the hole & then push another rawl plug in after it & it will hold the screw ok.

Thanks for the replies. I’ll probably use four London brackets for each 7ft shelf. It’s literally 2 shelves straight onto the wall and this way looked the most straightforward.
Can’t remember what the wood is but it’s good quality softwood, similar to pine in appearance.
Not sure if it needs any protector or varnish before putting up.
