Thank you for all your replies!!

So we have been using Babylove nappy pants for 2 years, but for some reason they aren't doing the job anymore. I have now tried Babylove dry nights, Huggies nappy pants and Huggies dry nights.

We had a leak free night 4 nights ago with the Huggies nappy pants and I though YES, we've cracked the code! Then he wet through the next 2 nights and last night he went through 3 of them! 8pm, 2am and 6am.

I'm thinking nappies may be the solution because he seems to be wetting out the side where the pull up type pants have webbing and not padding. I just feel sorry for my little boy going back into nappies. But he understands it's not his fault and we're trying everything.
