Council tax exemption is easy. As long as they only have students living in the house just google the Local Authority and you can usually complete the exemption form on-line.
And then once registered do consider applying for visitor parking permits if the property is in a CPZ. It makes a big difference for loading/unloading. And whilst on the website consider voter registration and bin collection timetables. Knowing the latter will help ensure neighbours are happy.
The big one is wifi. Because DD was collecting the keys in July, I went down with her and mentored her on utilities. Its been a bit of a marathon - as a landlord who has helped o'sea students through the process, it always is. Apply for broadband as soon as you can as it can take weeks, especially if there is a problem handing over the line. (After lots of frustration, and a special trip down to let the engineer in, her reward came this week when lots of her friends were moaning about no wifi.) Also watch out for credit checks. DDs credit rating is apparently good but we got the feeling that broadband and utilities are getting increasingly fussy. So DD is allowed to pay for water by DD but others may be asked to pay in advance.
And if the inventory clerk/landlord did not take meter readings, photograph the meter and email it to yourself. Part of DDs utility maze has been that the previous tenants appear never to have supplied meter readings, did not inform when they moved out or give forwarding addresses. In any event they should know how to turn off gas or water, unless the letting agency uses a 24 hour emergency service.
DD's new car has been to Lidl! The University bus service is not running yet, so she is being asked for lifts to/from sports training. What is nice is those that have asked for lifts have offered to contribute to petrol. We did the sums, based on the HMRC mileage allowance, and the amounts are tiny. But she is pleased money was offered.
