The only other crag I've come across with BBs is Sergeant Slab Crags but you'd need a 100m rope to bottom-rope stuff there and, dare I say it, it wouldn't be in the spirit of things....

Steel Knotts Bluff "is a small easy-angled slab of good rock that has some pleasant little climbs. There are a number of bolts on top that are used for belaying/top-roping. The grassy base and pleasant outlook add to the easy-going feel of the crag. There is not a lot of gear to be had on the routes if leading. It is quick drying and receives the sun from early in the day."

Plenty of the ones round outward Bound Eskdale have bolted belays ( or did have when I went OB 36 years ago)

Thornhow Crag, Grisedale

Pets Bridge Crag

Oxford crag at patterdale used by the outdoor centre has stakes and nice easy climbing for young ones. 

Lindale Slabs

All ok beginner venues. 

Church Crag

The bolts on Sergeant's Crag Slabs are off to the left at the top aren't they? The swing potential would be pretty spectacular and walking up to the top of the crag would defeat the whole point of the bolts being there in the first place (to avoid people disturbing vegetation in a SSSI):

+1 for Steel Knotts Bluff. Particularly good for kids and people new to climbing outdoors.

Been bolted for over 30 years. 

The abseil bolts are directly at the finish of Lakeland Cragsman (45m) but you're right that the access guidance is to not access or descend from the top by walking round, so still not suitable for setting up top-ropes for groups.

I found belay bolts on a crag on Pike o' Blisco but that was 30 years ago.  I think it was Long Scar. Small crag with some easy routes.

Out of curiosity, why do they need to be bolts? With your experience and 10m of static, you can make loads of crags top-ropable. 

Stickle Barn Crag and  Long Scar are 2 easily accessible single-pitch crags where anchors can be easily set up for top-roping.
