Your relationship
Six items of correspondence addressed to you and your partner at the same address as
evidence that you have been living together since your last grant of leave in this category, or
from the date you first started living together up to a maximum of two years. See Note 11.
Note 11 The items of correspondence should be addressed to you jointly or in both your names.
Examples of acceptable items are listed below. The documents provided must be originals.
Photocopies are not acceptable.
The dates of the items of correspondence should be spread evenly over the whole period you
are relying on. They should be from at least 3 different sources. If you do not have enough items
in your joint names, you may also provide items addressed to each of you individually if they
show the same address for both of you.
For example - Four items of correspondence in joint names to the same address and two items
addressed to each partner at the address. In total eight items would need to be submitted.
If you and your partner have no bills or correspondence in joint names, you will need to submit
twelve items (six each) of correspondence, evidencing that you reside together at the same
address.
我的问题是这里的“items”指的是一份东西（比如水账单），还是一类东西？举个例子，如果我提交过去一年里面的四份水账单，分别为3月份，6月份，9月份，12月份，这样是算一个item，还是4个item呢？
如果过去一年四份水账单加起来只算一个item，那six items 岂不是要过去一年的水单，一年电单，一年网络账单，一年council tax，一年银行账单，一年手机账单，这样加起来上百页纸呢
