Ecover's glass cleaner, limescale spray and toilet cleaner are all good, and not terribly expensive. Better than the equivalent Method products in my view. I also like Ecozone's 3 in 1 toilet cleaner. I don't think any of these come in big sizes, mind.
Ecover do a cream cleaner but I haven't tried it - using up the Cif and Stardrops our old cleaner left behind!
For surface cleaner, I like Method - I like French Lavender but others seem to prefer Pink Grapefruit or Satsuma - or Clean-ology, which you can get in some Waitroses. I also tend to wipe with (washable) microfibre cloths and water, which ekes the cleaner out a bit longer. The bottles are big, too - almost a litre. I find a bottle of Method lasts me six months.
With dishwasher tabs, I've tried and tried but none of the eco ones seem to work. I stick with Fairy or Finish, and drink through the guilt. 
Method washing up liquid is OK, not as aggressive as Fairy but it does the job and smells nice. Comes in big 1l refills if that's your thing. I never got on with Ecover wul.
Laundry I can't help with, unfortunately. I use Halo Sports Wash (I'm a personal trainer so get through a lottttttt of sportswear...) and Method that comes in the big 1.5l bottles. Both good (although Halo isn't eco) but I wouldn't want to make any claims or recommendations regarding eczema as I'm not a sufferer.
I can also highly recommend Ecozone's dishwasher and washing machine cleaning tablets. They're basically just citric acid, and very effective. They do something similar in powder form that gets the crust and limescale out of kettles, too.
Oh, I also have Method wood floor cleaner - it lasts for ages, my bottle's been going for almost two years - and wood furniture polish.
