About Quidworth
Honest money planning that’s on your side.
Free to use. No card needed. No ad-tracking. Your data stays private.

01 Why we exist
Most money tools are working for someone else.
UK personal finance online is a mess. The answer you came for is three scrolls and one email form away. The workings are hidden, so there is no way to tell whether a number is right or just flattering. And the genuinely useful stuff tends to sit behind a paywall or a “book a call” button.
So we built the opposite: one clear plan that shows where your household is actually heading, does the maths straight, and shows its working, so you can check every figure rather than take it on trust. That is the entire idea.
02 What we believe
Four things we are built around.
Free to use
Open it and start planning - no card, no countdown, no trial clock. The calculators and the household plan are free to use, and we would rather earn your trust than your card details on day one.
Honest maths
We show the real numbers, including the unflattering ones. No get-rich promises, no false free lunches. Every projection is something you can check yourself.
Private by design
Your household's numbers are only ever visible to your household, never to other users. And we do not sell your personal data.
No ad-tech chasing you
No ad networks and no advertising trackers quietly following you around the web after you leave. Our analytics is cookieless and runs on our own servers.
03 What you can do
Three ways in - all free.
The planner, the calculators and the blog are the same maths seen from three distances. Start wherever your question is.
04 Where we are heading
The most trustworthy place to plan UK money.
We want Quidworth to be the place people reach for whenever a money question comes up, from “can we afford this?” to “are we on track to retire?”, and to trust the answer because they can see exactly how it was worked out.
We will keep adding tools and writing. And we will hold on to the things that matter most: a free plan that is genuinely useful on its own, honest maths, and your data staying yours.

Projections, not advice
Projections are estimates for education, not financial advice. They are simplified estimates for your own planning, not a personal recommendation. For significant decisions, speak to a regulated adviser. How we work out projections
Your data stays yours
Your household’s data lives in a private database, visible only to your own household, never to anyone else using Quidworth, and we do not sell it. Read our privacy policy
