What Arken actually costs
Arken publishes its prices, which is more than some do. They are just packaged in a way that makes the headline number hard to compare with anything.
Arken publish their prices, which is more than several providers in this market do. The difficulty is that capacity is sold in packs and capability is sold in modules, so the headline figure describes very few real practices.
All figures below are from Arken's own plans and pricing page, checked 14 September 2026.

|---|---|
| Arken Professional, 10-document pack | £107 + VAT |

What a real practice pays#
A sole practitioner drafting around forty documents a month and offering trusts:
| Excl. VAT | Incl. VAT | |
|---|---|---|
| Arken Professional base | £107 | £128.40 |
| Three further packs | £37.50 | £45.00 |
| Trust Referencer | £40 | £48.00 |
| Total | £184.50 | £221.40 |
Against Willo at £150, with no VAT to add, no document cap and trust drafting included.
The structure has an awkward consequence: every step that makes a practice more profitable — more documents, offering trusts, adding Scotland — also raises the software bill. The month your average fee goes up is the month your costs do.
Commitment#
Arken's materials refer to annual commitments. Worth establishing the term and the notice period before signing, because it determines how expensive a change of mind is. Willo is a rolling month with no notice period and no exit fee.
