Editorial standards
Our guides explain official UK letters in plain English. Every guide is written and reviewed by the OneLetter editorial team, checked against official government and independent-advice sources, and dated so you can see when it was last reviewed. This is information, not legal advice.
Who writes these guides
OneLetter's guides are written and maintained by the OneLetter editorial team. We are not a law firm, a debt-advice charity, or a government body, and we have no affiliation with the organisations that send the letters we explain. Our job is narrow and specific: to explain, in plain English, what a particular official letter means, what it usually asks you to do, what the deadlines are, and where to get free, independent help.
How we research and check the facts
Every guide is built from primary, authoritative sources rather than second-hand summaries. In practice that means we check the details — figures, deadlines, legal steps and your rights — against official sources such as GOV.UK, legislation.gov.uk, the NHS Business Services Authority, and established independent advice organisations including Citizens Advice, Shelter, StepChange and National Debtline. The sources we relied on are listed at the bottom of each guide so you can read the full detail yourself.
Where the law or a figure has recently changed, we say so and give the date it changed. UK rules on debt, benefits, tax and housing are updated regularly, so we treat currency as part of accuracy, not an afterthought.
Review dates
Each guide carries a visible "Last reviewed" date, and that same date is published in the page's structured data. When we revisit a guide and confirm or update its content, we update that date. If a guide has not been reviewed recently, the date tells you honestly how old the information is.
Corrections
If you spot something that is wrong, out of date, or unclear, please tell us at hello@oneletter.uk. We take corrections seriously on money, benefits, tax and legal content and will fix genuine errors promptly.
Information, not legal advice
OneLetter is for information only. It does not provide legal, financial or debt advice, and reading a guide does not create any professional relationship. Your circumstances may change what the right course of action is. For advice on your own situation, please contact a qualified adviser or one of the free services below.
