I still get the same IP 99% of the times on MER that said my connection doesn't drop out ever so I very rarely disconnect.

Well, that is going to help! If you don't disconnect and your router always renews DHCP lease every hour, you'll keep the same IP.

Sky DHCP IP allocation for MER Fibre, at least from what I have seen......

First time DHCP request from client, you'll get an IP with a lease of 10 mins. If you renew before the lease expires, you'll get the same IP with a lease time of 1 hour. As long as you keep renewing before the 1 hour expires, you'll keep the same IP with a lease time of 1 hour.

I've not seen any stickyness. Lease expires, even by 1 second, IP is returned to DHCP pool and you'll get another.

There's definitely at least been some stickiness.

I've had building works carried out with electric down for a few days and got the same IP back.
& powercuts lasting a few hours often give me the same IP

I haven't disconnected in a long time so cannot comment on whether that's changed recently but certainly 6 months ago it wasn't giving me new ones willy nilly. Perhaps just flook though.

The way the DHCP client works is that it will start requesting a lease renewal after half the lease time, in Sky's case after 30 mins, so in reality if there aren't any problems the lease is renewed every 30 minutes.

if he is on pppoa then extending the ppp timeout on the router so its longer than a resync takes may allow the ip to stay (this works on BT). But with the caveat been accept the ip profile will not update, of course sky dont use ip profiles, so he basically should have no noticeable downside doing this.
