Just avoid Redstone Wills.
I tried to use them, for £150, after becoming a home owner. They made a total hash of writing my will, three separate times. They used the name of my executor as my mother, (I, my dad and my mum all share our last name...and my executor was a male Indian friend)! They didn't tell me what to do with my letter of wishes, but tried to incorporate it into the will and made a huge mess of that, they got the division of funds wrong, on and on. I would return forms to them with all the corrections, having written exactly what I wanted, and they would re-write, not what I wanted, and even manage to introduce errors to areas that had been fine.
The whole thing took so long that eventually we all just gave up. I spent £150 and didn't get a usable will, and they spent way more hours than £150 would have paid for. I am convinced they either had the wills written by (dumb) computers, or by non-English speakers, possibly in India.
To this day I do not know how to leave a record of what I would want to have done with possessions which do not have easy conversion to a monetary value. Houses, cars, furniture, all pretty easy. Tools, camping gear and similar hobby materials/supplies probably have a lot of ££ tied up in them in aggregate, but they are fiddly to sell at a good price. Maybe you would rather they go to friends...and that is where it is hard, apparently. There is also the issue that if you try to go too fine in doling out possessions, what if you no longer have them by the time you go? Seems like you need to bundle...all workshop tools to X, all camping gear to Y, all furniture to auction proceeds to Z.
Best of luck!
