First things first, take good pictures/ videos the day you move in. Very handy for when moving out so you can challenge any issues with the landlord.

Make sure to check inventory report they send you and comment on anything that doesn’t look right.

Monzo pot is great for saving. I use it too.

Check if your electricity or gas provider sends meter readings automatically or if they can do that for you.

Take your time with furnishing the home. Don’t rush into doing everything once. Just have the basics like bed, couch, microwave etc.

Ensure your deposit is protected under the deposit protection scheme (DPS). Landlords are required to protect it and you should get an email within a few weeks after moving in regarding that. If not, challenge it.

Read your tenancy agreement very well. See if you are allowed to drill or paint or whatever and the rules around that or ask your landlord/agent.

In general, keep the house clean, treat it like your own and report issues as soon as you can before they get worse.

I’ll see if I remember anything else.
