Business Introduction Letter Template (UK)

Make the UK relevance obvious

The first paragraph should not be a general company history. It should state the commercial reason for contact: a referral, event, procurement route, geographic expansion, sector fit, supplier search or problem the recipient appears to have.

This template asks for that connection separately from the company description. A recipient should be able to forward the letter internally and have the next reader understand why it arrived.

Use substantiated proof points

The Bribery Act guidance is the local anti-bribery anchor for commission-led business development. Keep introducer payments documented, proportionate and free from improper influence.

Keep the proof modest and verifiable: client type, relevant certification, years trading, case study, service coverage, measurable outcome or reference. Do not imply government approval, exclusive status, guaranteed savings or a live partnership unless it is accurate and authorised.

Email outreach has local rules

For outreach, ICO guidance distinguishes corporate subscribers from sole traders and some partnerships under PECR. Corporate B2B email does not need PECR consent, but the sender must identify itself, provide an opt-out address and still respect UK GDPR objections where personal data is used.

That is why this template includes optional footer or opt-out wording for email use. It also keeps the subject line factual, because a clever subject that hides the commercial purpose can create more risk than attention.

Ask for one next step

A strong introduction does not ask for a purchase, partnership, demo, referral and data-room review all at once. Ask for a short call, the right contact, permission to send a proposal, a supplier-registration route or a meeting at an event.

The follow-up field lets the sender say when they may follow up, without sounding like a legal deadline. This is especially useful in the United Kingdom, where professional tone often matters as much as the words.

Use local letter identity details

Use a UK trading address or registered office where the letter may be relied on as a business record.

Even if the letter is sent by email, a complete sender identity gives the recipient confidence and lets them route the message. For regulated or investor-facing introductions, the letter should also avoid implying authorisation or licence status unless verified.

  GOV.UK marketing and advertising law

• Do not overstate relationships

• Avoid regulated solicitation

  Investment, finance, insurance, lending and public-procurement introductions in the United Kingdom may need special wording or authorisation.

  FCA appointed representatives

• Minimize personal data

  Use only the contact information needed for the introduction and respect objections or opt-outs.

• Keep attachments proportionate

  Use one capability statement or link where needed, not a pile of unsolicited files.
