Learn Bitcoin: guides to buying, holding and spending Bitcoin in the UK
These Bitcoin guides are for people in the UK and the Isle of Man: how to buy Bitcoin step by step, how Lightning payments work and how Bitcoin is regulated and taxed. Each one is written by the CoinCorner Research Team, reviewed by compliance before publication, dated, and sourced to regulators and original documents.
For information only. Not investment advice. Last updated .
Start here: three pillar guides
New to Bitcoin? Read these three in order. Each takes about a quarter of an hour and stands on its own, so you can also go straight to the one you need.
This hub is for two kinds of reader. The first lives in the UK or the Isle of Man, has heard plenty about Bitcoin, has not bought any yet and wants to understand the rules, the costs and the risks before putting money in. The second runs a business, has been asked whether the shop, the website or the invoice can take Bitcoin, and needs to know how such a payment ends up as pounds in the business account.
The guides take the questions in the order a beginner tends to meet them. Is it legal, and who oversees the firms that sell it? How do you buy it, what does it cost and which records will you need for tax? And what is the Lightning Network that lets a Bitcoin payment arrive in seconds? Each guide opens with a short answer, lists its key points in a box at the top, works through the detail under plain headings and ends with common questions and a numbered list of sources.
They are written from the point of view of the CoinCorner Bitcoin exchange, which has helped people and businesses buy, sell, send, receive and store Bitcoin since 2014. Where a guide uses a CoinCorner product as its example it says so and links to the page with the published terms. Where a rule comes from a regulator or a tax authority, the guide links to the original document and gives the date it was read.
None of this tells you whether to buy. The price of Bitcoin can fall sharply, and CoinCorner and investments in cryptoassets are not covered by the Financial Ombudsman Service and are not subject to protection under the Financial Services Compensation Scheme. Read the risk disclosure for Bitcoin buyers before you put money in.

How to buy Bitcoin in the UK: step by step
Five steps, from choosing a provider you can check on a public register to deciding where your Bitcoin is kept, with payment methods, ID checks, fees and tax basics.

What is the Lightning Network and how does it work?
A payment layer on top of Bitcoin that settles small payments in seconds. How channels, routing, invoices and LNURL work, and what happens when a Bolt Card is tapped.
Buying and holding Bitcoin
A first purchase raises practical questions: which payment method to use, what it costs and where the coins sit afterwards. On CoinCorner the smallest purchase is £1, you pay by bank transfer or debit card, and credit cards are not accepted. The guide explains each step, and the product pages carry the terms.

Lightning and Bitcoin payments
Lightning is the part of Bitcoin built for small, frequent payments. The guide covers the mechanics. The payments page covers what a business gets from CoinCorner Checkout: Bitcoin accepted in a shop, online or by email invoice for a 1% fee, converted to pounds or euros.

Regulation, protection and tax
Before you rely on any firm, check who it is, where it appears on a public register and what that entry does and does not cover. The guide explains the UK position and the tax basics, and the pages listed here show how it applies to CoinCorner. These guides are information, not investment or tax advice.

Glossary
The guides use a small set of technical words. The Bitcoin glossary defines 24 of them in a sentence or two each. Here are ten to start with.
Costs and checks
- Network fee: the bitcoin a sender pays so that miners include the transaction in a block.
- Spread: the gap between the price a service sells at and the price it buys back at.
- KYC: the identity check a firm completes before it opens an account.
Keys and custody
- Private key: the secret data that proves the right to spend the bitcoin in a wallet.
- Custody and self-custody: whether a company holds the keys for you or you hold them yourself.
- Multi-signature: a wallet in which more than one key must sign before Bitcoin can move.
Payments and protection
- Payment channel: bitcoin that two participants lock up and then pay each other from, off the main chain.
- Bolt Card: an NFC contactless card that pays over the Lightning Network.
- E-money: money stored electronically, such as the pounds in an online account.
- FSCS: the UK compensation scheme, which does not protect Bitcoin held with CoinCorner.
How these guides are written and reviewed
Every guide is prepared by the CoinCorner Research Team and reviewed by the Head of Compliance before it is published. Both are role names for now: each guide will carry a named author and a named reviewer, with a profile page for each, before it goes live.
- Sources come first. Rules and figures are taken from regulators, legislation, technical specifications and CoinCorner's own terms and product pages, and every guide ends with the list of sources it used.
- Everything is dated. Each guide shows when it was published and last updated, and figures carry the date they were read.
- Corrections are visible. When a mistake is fixed, the page says what changed and when. To report one, tell the support team which page and which sentence.
- No predictions. Guides make no price forecasts and no claims about returns.
The editorial policy sets out the full process, including how AI tools are used in drafting. The about page shows who writes for CoinCorner and which companies stand behind it.
