I never said anything needed a basking light (though the toads would enjoy it) I said they are known to bask in the wild, meaning they would receive UVB from the sun, like they would with a UVB bulb. I know they aren't tropical animals, I keep mine at a steady 75F just now. Hmm, I just wouldn't chance it, I'd rather pay £10-£20 more on a bulb and know it's the right one.

If you decide to take on an animal, look up the latest care from good sources and get the equipment needed before getting the animal or be prepared to pay additional costs and be in an awkward situation but I've found a lot of it to be trial and errors along the way. I'm guilty of underestimating how much frogs would cost to keep when I first started out but I paid the cost and I've spent a lot of money on my frogs and I ain't well off. I understand you're in a bad situation but I don't understand how you can bring the price of the animal into the situation. You can keep them without UVB, it's been done but it's been proven that it benefits them and all diurnal animals share a relationship with the sun. Ideally, I'd recommend when you have the money just get a cheap light dome and 5% uvb, in the mean time make sure dust with calcium with D3
