Consider what new service you sign up to
Owning your own home gives you a level of stability that certainly increases your options with service providers, as you may be able to access better-priced deals if you are in the position to commit to a longer-term agreement.
If you are renting your new property, it may be beneficial in the long term to sign a no lock-in contract, giving you the freedom to cancel or change your plan can provide flexibility.
From there, be open with providers about exactly what you want to achieve with your internet connection. What kind of speeds do you require? At home, do you use it mainly for social, professional or entertainment? The first is relatively light on data-binging, but the latter two may rely upon transferring significant files or streaming regular movie-length HD videos. By also consolidating your service providers when you move, you could cover both bases at once.
Where offers appear similar, it's always recommended to spend some time reading over the review provided online.
While anecdotal evidence from friends and family can pull you in different directions, paying closer attention to those that live within a relatively close distance of your location will help, as they will be familiar with the potential quirks of your new postcode.
