Editorial policy
How we decide what to publish, where the numbers come from, how the site pays for itself, and what happens when we get something wrong.

Who writes this
DecentralisedChain is written by Firoz Khan, who has been investing on and off since 2008 and works in product management. Firoz is not a financial expert and does not claim to be. We are here to explain how things work, show the real numbers and be honest about the mistakes people make, not to tell you what to do with your money.
Where the numbers come from
Rules and rates come from primary sources wherever they exist: gov.uk and HMRC guidance for tax, pensions and allowances, the FCA and its register for regulation and authorised firms, and a provider's own published terms for product details.
Tax thresholds, allowances and rates are checked against the current UK tax year and updated when they change. Every article shows the date it was published, so you can see how current its figures are. Each calculator has a "How we calculate this" note explaining its assumptions.
Independence and money
Commercial relationships never determine our editorial opinions. Some articles contain affiliate or sponsored links, and we may earn a commission if you sign up or buy through them, at no extra cost to you.
Posts with affiliate links carry an "Advertisement, contains affiliate links" stamp near the top, and paid placements are labelled "Advertisement". The full wording is in our disclaimer.
Advice and risk
Nothing here is financial advice or a personal recommendation, and we do not take your circumstances into account. Higher-risk crypto content carries the FCA risk warning, and we do not describe crypto as safe or guaranteed. Only invest money you are prepared to lose.
Corrections and updates
If a figure, threshold or rule is wrong or out of date, email biz@decentralisedchain.com or use the contact page. A reader who spots a mistake is doing us a favour.
When we correct something that changes what an article says, such as a figure, a rule or a conclusion, we fix it and add a dated note to the article saying what changed. Typos and small wording fixes are made without a note. When an article is substantially revised, the page shows an "Updated" date next to the published date.
