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.

- Cheapest UK will product — entry point for any budget
- Available in physical Post Office branches (no online required)
- Recognisable brand — older relatives may prefer buying in person
- Functionally produces a Wills Act 1837–compliant Will when signed correctly
- Pre-printed form — once it's filled in, mistakes mean a new kit and re-signing

- Not all branches stock it; availability inconsistent
- Any situation more nuanced than 'everything to my one spouse'
- Couples wanting matched mirror wills (we have a dedicated kit)
- Cohabiting partners (we have a dedicated kit; Post Office doesn't)

The document is legally identical.
Every Will that complies with section 9 of the Wills Act 1837 — signed by you in the presence of two qualifying witnesses, who both sign in your presence — has the same legal weight in England & Wales. The difference between providers is price, process, and what happens after you sign.

Plain-English questions UK searchers actually ask before choosing a will provider. Reply to richard@compareengineering.com 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.
