WillSafe UK
vs Post Office.
The Post Office Will Kit is the cheap pre-printed option. Here's why we charge a little more, and why it's worth it.
The Post Office Will Kit is the cheapest will product on the UK market at around £25 for a pre-printed pack. It's a basic kit, fillable blanks on paper, no editable file, no detailed signing instructions, no updates when the law changes. WillSafe is £40 (£15 more) but you get a DOCX + PDF, a signing & witnessing checklist, plain-English instructions, and 12 months of free updates. If you can afford the extra £15, it's the difference between a Will that's fine for the next 18 months and a Will that grows with your life.

The document is legally identical.

Plain-English questions UK searchers actually ask before choosing a will provider. Reply to richard@willsafe.org.uk if yours isn't here.
01Is the Post Office Will Kit legally binding?+
Yes, when signed correctly under section 9 of the Wills Act 1837. The legal weight is the same as any other Will. The risks are practical: handwritten mistakes, ambiguous wording, and the witness-disqualification rules (s.15 Wills Act) that the kit doesn't fully explain.
02Should I buy the Post Office Will Kit or WillSafe?+
If your budget is £25 maximum and your situation is very simple (single person, no dependants, leaving everything to one person), the Post Office Kit is fine. For anything more, couples, cohabitees, children, property, or anyone who'd rather have an editable Word file you can update, WillSafe is the better £15 spend.
03What happens if I make a mistake on the Post Office form?+
You'll need to either correct it (and the correction must be initialled by you and both witnesses, in a specific way) or buy a new kit. With WillSafe's editable DOCX, you just retype the wrong line and re-print. This is the single biggest practical difference.
