Quick answer

A UK visitor visa invitation letter is a note from your UK host that explains who you are, why you’re visiting, when, where you’ll stay, and who pays. It supports the application. It does not replace the visitor’s own evidence.

What an invitation letter is for

When someone in the UK invites a family member or friend to visit, an invitation letter helps the caseworker understand the trip. It puts the visit in context. It shows the relationship, the plan, and the accommodation.

The letter is a support document. The visitor still needs to show their own ties to home, their own funds, and their own reason to return. Think of the letter as one piece of the file, not the whole file.

Rules and document lists change. Confirm the current requirements on gov.uk before you apply.

What to include

A clear invitation letter usually covers each of these points:

  • The host’s full name, UK address, and immigration status in the UK (for example, British citizen or settled).
  • The visitor’s full name and passport number.
  • The relationship between the host and the visitor, and how long they’ve known each other.
  • The purpose of the visit and the exact dates the visitor plans to arrive and leave.
  • Where the visitor will stay during the trip.
  • Who is paying for the trip, and any specific costs the host will cover.

Keep it short and honest. Sign and date it. If the host is sponsoring part of the trip, the letter should match the host’s financial documents.

Sample invitation letter

The names and addresses below are made up. Use them only as a guide, then write the real details.

  • From: Marcus Bramble, 14 Hollow Lane, Manchester, M20 4TX, United Kingdom
  • Date: 1 October 2026
  • To: The Entry Clearance Officer

Dear Sir or Madam,

I’m writing to invite my sister, Adaeze Bramble (passport number A1234567), to visit me in the United Kingdom. I’m a British citizen and I live at the address above.

Adaeze plans to visit from 5 December 2026 to 20 December 2026 to spend the holidays with our family. She’ll stay with me at my home for the full trip. She’ll return home to continue her job after the visit.

I’ll cover her accommodation and meals during her stay. She’s paying for her own flights and travel insurance. I’ve attached my bank statements and a copy of my passport to confirm my status and support.

Please contact me if you need anything more.

Yours faithfully,

Marcus Bramble

Documents to attach

The letter works best with proof behind it. Common attachments include:

  • Proof of the relationship, such as photos together, messages over time, or family records.
  • A copy of the host’s passport or immigration document to show status.
  • The host’s proof of address, such as a council tax bill or tenancy agreement.
  • If the host is sponsoring, the host’s financial documents, such as recent bank statements and payslips.

The exact list depends on the case. Check the current guidance on gov.uk and confirm what applies to your situation.

Common mistakes

  • Vague dates. Give exact arrival and departure dates, not a rough month.
  • Money that doesn’t match. If the host offers to pay, the host’s bank statements should back that up.
  • Leaving out the host’s status. State clearly whether the host is a citizen, settled, or here on a visa.
  • Treating the letter as the whole application. The visitor still needs their own evidence of funds and ties to home.
  • No signature or date. An unsigned letter looks unfinished.

FAQ

Do I need an invitation letter to apply?

No, it isn’t always required. It helps when you’re staying with a host or a host is paying. Check gov.uk for the current guidance for your visit type.

Who signs the letter, the host or the visitor?

The host in the UK writes and signs it, since it’s their invitation. The visitor submits it with their own application and evidence.

Does a strong invitation letter guarantee a visa?

No. The caseworker weighs the whole file. A clear letter helps, but the decision rests on all the evidence, including the visitor’s own funds and ties to home.
