I agree with tinkerbell and mamya, adult incontinence pads can be quite steeply priced to buy privately, he would be better getting a referral from his doctor and being assessed by the incontinence service
The NHS do provide incontinence pads in Brighton,East Sussex, but only in very LIMITED quantities.
I buy them for my wife from Hartmann.
The pads are Molimed and are available in 2 sizes, MIDI or MAXI.
The last price we paid was £4.03 for a pack of 28 (postage is extra)
They are VAT exempt.

I got them delivered by NHS free when caring for FIL...if you have a medical condition then you ought to speak to gp about supplies...free in Scotland and Wales I think too !
