## What it does

The skill covers writing for a British audience: client emails, chat messages, proposals, blog posts and web copy. It applies to drafting, editing, and tone-checking finished text.

Inside is an EN-GB spelling table: `colour`, `organise`, `centre`, `licence` as a noun against `license` as a verb, `travelling` with a double L, `catalogue`, `judgement`. It separates `enquiry` from `inquiry`, `kerb` from `tyre`, and `programme` from `program` in computing. Dates follow Day Month Year with no comma, never Month/Day/Year.

There is a formality ladder, from a bare "Hi" in internal chat up to "Dear Sir or Madam" and "Yours faithfully" in a formal letter. The skill insists on the split between "Yours sincerely" for someone you know and "Yours faithfully" when you don't — getting that wrong reads as careless. It also lists Americanisms to replace, such as `reach out`, `touch base`, `circle back`, and `leverage` as a verb, plus forced Britishisms like "cheerio" and "old chap" to keep out of business writing.

The rules and examples are written in English, so the skill is no help for correspondence in another language.

# UK Business English

Professional and measured. Polite without being obsequious. Direct without being abrupt. Naturally British without being a caricature. Write like a competent professional who happens to be British -- not like a Dickens character, not like an American tech startup, and not like someone who just discovered the word "whilst".

## Spelling (EN-GB)

| Pattern | British | Not |
|---------|---------|-----|
| -our | colour, favour, honour, behaviour | color, favor |
| -ise | organise, realise, specialise, recognise | organize, realize |
| -re | centre, fibre, metre, theatre | center, fiber |
| -ence | licence (noun), defence, offence | license (noun), defense |
| -ise/-ize | Both accepted in GB; prefer -ise for consistency | — |
| Double L | travelling, cancelling, modelling | traveling, canceling |
| -ogue | catalogue, dialogue, analogue | catalog, dialog |
| -ement | judgement, acknowledgement | judgment (legal only) |

**Noun/verb splits:**

| Noun | Verb |
|------|------|
| licence | license |
| practice | practise |
| advice | advise |

**Common traps:** enquiry (general), inquiry (formal/legal), kerb (road edge), tyre (wheel), programme (general), program (computing), cheque (payment), grey (not gray).

**Date format:** Day Month Year, no comma -- 15 January 2026. Abbreviated: 15 Jan 2026. Never Month/Day/Year.

## Tone Ladder

Match formality to context. Default to "polite professional" -- a step more formal than Australian or American baseline, but still warm.

| Context | Formality | Greeting | Sign-off |
|---------|-----------|----------|----------|
| Slack/Teams (internal) | Casual | "Hi" / first name | None needed |
| Email to existing client | Polite professional | "Hi [Name]" | "Kind regards" / "Thanks" |
| Email to new client | Professional | "Dear [Name]" / "Hi [Name]" | "Kind regards" |
| Proposal or quote | Professional | "Dear [Name]" | "Kind regards" / "Yours sincerely" |
| Follow-up after meeting | Polite professional | "Hi [Name]" | "Kind regards" / "Thanks" |
| Cold outreach | Professional | "Dear [Name]" / "Hi [Name]" | "Kind regards" |
```
