How to send a fax to United Kingdom

Why fax to United Kingdom?

While the UK has moved much of its business communication online, fax remains in active use across the NHS, solicitors' offices, courts, and government departments. Many GP surgeries and hospitals use fax to transmit medical records, referral letters, and prescriptions. HMRC and other agencies accept faxed documents for certain filings.

If a UK organization provides a fax number on their contact page, they expect to receive documents that way — and it is often faster than posting a letter.

What you need

To send a fax to United Kingdom with unofax you need four things:

• Your document: PDF, Word, image, or any supported file. PDF gives the best results.
• The UK fax number — the country code is +44. A typical number looks like +44 20 7946 0958 (London) or +44 161 496 0123 (Manchester). Drop the leading zero from the area code when dialing internationally.
• A payment method: credit card, debit card, Apple Pay, or Google Pay.
• Your email address: for delivery confirmation and proof of receipt.

No account, no subscription, no fax machine required.

Step by step

Sending a fax to United Kingdom with unofax takes about two minutes:

• Upload your document: drag and drop or tap to select your file.
• Select the United Kingdom and enter the fax number: choose the UK from the country list. Type the number without the leading zero. unofax adds the +44 country code automatically.
• Enter your email: provide your email address for delivery confirmation and proof of receipt.
• Preview: check each page in the preview. Add a free cover sheet if the recipient requires one.
• Pay: the per-page price is shown upfront. Pay with card, Apple Pay, or Google Pay.
• Done: your fax is sent immediately. You receive a delivery confirmation once the receiving machine acknowledges receipt.

Tips for faxing to United Kingdom

A few things to keep in mind when faxing to United Kingdom:

• Business hours: UK offices typically work 09:00-17:00 local time. Sending during business hours can improve the chance that someone sees and routes the fax promptly.
• Drop the trunk zero: UK numbers often start with 0 locally. Remove that zero when entering the number for international delivery.
• Include references: NHS, legal, and government recipients often need a case, patient, claim, or matter reference on the cover sheet.
• Use PDF for best quality — UK organizations frequently print incoming faxes. A clean, high-contrast PDF ensures your document is legible.
• Freephone numbers supported: unofax can send to many UK 0800 and 0808 fax numbers. Enter the number without the leading zero.

Common United Kingdom fax situations

These are the kinds of local workflows where a fax number can still be the requested channel:

• NHS and private healthcare referrals: fax still appears around clinic referrals, records transfers, and administrative forms where an email inbox is not the accepted channel.
• Solicitor and conveyancing documents: law firms may request faxed signed paperwork when they need a clear transmission trail.
• Local authority paperwork: councils and public bodies sometimes retain fax numbers for legacy forms and formal correspondence.
