Does Sky charge if you need a new LMB during house move?

We currently have Sky BB, phone and TV and will be moving house later this year. Whilst the new place has a dish it wasn't installed by the current owners. If Sky have to install a new LMB do they charge and/or does moving renew your contract? My contract is up in Feb next year and I am not sure I will be renewing this time. Been a customer for 30 years but now watch 1/4 what I did 5 years ago do to other streaming services.

There's no charge for replacing an LNB (low-noise block downconverter) but Sky are understandably reluctant to make that investment outside a minimum contract term.
