What to check at the cheap end
A from price is not a price. Utility Warehouse publishes £5 as a from figure and its £23 unlimited plan the same way; the figure you get depends on what else you buy.
The data on the rung matters more than the rung. Lycamobile's £7.50 buys 75 GB and SMARTY's £6 buys 5 GB, which are not comparable plans at comparable prices.
Running out is priced. SMARTY publishes that an add-on costs £1 per GB, the same rate as the data in the plan, which is unusually plain and worth asking every seller.
Cheap plans are where terms hide. Check whether the rung is a rolling month or a tie, and whether the price rises in April.
