I used to work in lettings and trying to explain to some tenants that if each month were 4 weeks there would only be 48 weeks in a year had me banging my head on the desk
Lol, trying to teach budgetting to people with learning disabilities when bills are paid monthly but benefits are paid fortnightly or 4-weekly is pretty challenging!
In benefits. the rules for converting a weekly rent to a monthly amount and vice versa are different for universal credit and housing benefit.
HB is paid weekly. To get a weekly rent figure, HB uses
(monthly rent 12)/365 7
To get a monthly amount from a weekly rent, UC uses
(weekly rent * 52)/12.
If you convert a monthly rent to weekly using the first formula, then convert the weekly figure using the second formula, they do not come out the same! I think the difference is about £3 on a monthly figure of £1,000.
Because social housing landlords still charge rents weekly, running from Monday to Sunday, and this year has 53 Mondays, UC claimants were going to lose out on a week's rent. I believe they have now agreed to pay the "extra" week, but haven't seen this in black and white, so it may not be true.
And don't get me started on the bonkers situation for UC claimants who have their rent deducted at source and paid direct to landlords. The team that deal with this still make payments 4-weekly, but deduct a monthly amount from claimants. The DWP can't tell us how they're going to avoid paying 13 months' rent in a year!
