I run Tomato. By default it probably hasn't classified your NTP packets as lowest priority. But you can boost the priority.
NTP is a UDP protocol on port 123. So classify that high priority and things should improve somewhat. In Tomato, you do this by going to QoS / Classification and configuring a rule for UDP port 123. If you're on an asymmetric link like ADSL there's only so much QoS your router can do. In particular if your lodger is downloading lots of big files via BitTorrent your incoming connection is going to be saturated and your router can't usefully shape incoming traffic. So incoming NTP requests will still be delayed, but at least Tomato should be able to expedite the outgoing requests. Your best solution is to talk to your lodger and ask him to knock it off. If he's using Bittorrent, ask him to install a client like uTorrent that supports bandwidth throttling, then have him set it at 75% of your incoming bandwidth.
