Recommendations for a PO Box provider

[Katapult]

I'm hoping someone will have experience of this.

I need to set up a PO box for my ex to send correspondence to (court ordered). Royal Mail is over £400 a year. There are various ones I've found (mostly London based) that offer service from around £30 plus cost of sending post on to my address and a handling fee. I'm not in London. Likely to be no more than one card/letter per month. Any suggestions of providers that you know are legit?

Thank you in advance.

We have always used mailboxes etc

but they are likely to be around the same if not more in price. Used them for the best part of 25 years.

never used these, but know a lot of very pleased boaters who have. No idea of cost.

Your ex needs to set it up.

You can send items directly to the parcel lockers, only costs £1.99 (possibly plus VAT):

InPost | Send a Parcel | Fast, Easy Drop-Off Shipping

However, you only get 3 days to collect the item and you'll need to give your ex a locker location to send to, so might not be suitable if you're keeping your location private due to domestic abuse, especially if there's a risk of him hanging round the locker until you collect. You'd need to give him an email address and phone number but that could be burner versions if you don't want him to have your main contact details.

Unfortunately court ordered I pay and set up as it gives me control of location and I can vet what is sent to the children. He also says he has no money.

Thanks @Alphabet1spaghetti2 I was going to use MBE but they've closed my local office and it's a trek to get to their next nearest to pick up. It costs to send the post on to me so will increase the cost and won't be that much cheaper than RM then.

Boatmail looks interesting so will give them a call tomorrow. Inpost won't work with the ex unfortunately!

Found one called UKpostbox which has good and bad reviews and is cheaper but no contract so might be worth a punt.

Thanks everyone for your help.
