BFPO addresses and mortgages: buying a home while posted overseas
A BFPO address is the British Forces Post Office address used by serving personnel, their families and some MOD staff posted overseas. You can get a UK mortgage while using one. The hurdles are practical: lender systems, credit checks and signing documents from abroad. With some preparation, most of them can be managed.

What is a BFPO address?
BFPO stands for British Forces Post Office. It's run by the Ministry of Defence and delivers mail to serving armed forces personnel and their families overseas, and to MOD employees and some other officials entitled to use it.
Instead of a street and town abroad, mail is addressed to a BFPO number. GOV.UK sets out the format like this:
| Line | What goes on it |
|---|---|
| 1 | Service number, rank or title, and name (family members start with their own name, then "C/O" and the service person's details) |
| 2 | Unit, regiment or HM ship |
| 3 | Operation name, if deployed |
| 4 | BFPO number, never the town or country |
Since 2012, each BFPO number has also had a UK-style postcode starting BF1, such as BF1 0AB for BFPO 16. These were brought in because many websites and computer systems wouldn't accept an address without a normal postcode. BFPO numbers and postcodes are listed on GOV.UK.
Can you get deliveries to a BFPO address?
Often, but not always. GOV.UK says not all UK online retailers can send to BFPO, so check before you order. Items must go through Royal Mail, Parcelforce, the Post Office or a courier on BFPO's approved list, and online orders are limited to 30kg. GOV.UK also advises against using the BF1 postcode version of your address when shopping online. Delivery usually takes longer than within the UK.
Why a BFPO address can cause problems with a mortgage
Lenders are used to applicants with a normal UK address, a few years at it, and a matching record with the credit reference agencies. A posting overseas can break that pattern.
| Check | What can go wrong while posted |
|---|---|
| Address history | Lenders typically ask for three years. Some application systems won't accept a BFPO address, or treat it as a foreign one |
| Residency rules | Many lenders' criteria are written for civilians living abroad, who they may decline or treat as expats. Some make an exception for serving personnel |
| Credit file | If your accounts are registered to an old address, or you've come off the electoral register, your file can look thin or out of date |
| ID checks | Electronic identity checks often match your name to a UK address. A BFPO address may not match, so extra documents can be needed |
| Income | Overseas allowances are linked to the posting, so lenders may leave them out and use basic pay |
None of this means a decline, but lender choice matters more than usual. A wrong application can leave a credit search for nothing.

How to keep your credit file mortgage-ready while posted
Credit file checklist
- Register to vote
- Forces personnel posted abroad, and their spouses or civil partners, can register as service voters through GOV.UK. It lasts up to five years. Check your credit reports to see how it shows
- Keep UK accounts
- Keep a UK current account and pay credit commitments on time. Long-standing accounts help lenders see a stable history
- One address
- Use the same UK correspondence address, where allowed, across your bank, cards and phone contract so records match
- Check your reports
- Look at all three main credit reference agencies, fix errors, and remove old financial links to ex-partners
- Explain if needed
- You can add a short notice of correction to your file to explain gaps linked to service overseas
Our guide to credit scores and mortgages covers the basics in more detail.
Can I get a mortgage with a BFPO address?
Yes. Some lenders will lend to serving personnel posted overseas as long as the rest of the application fits their criteria. Lenders tend to look for:
- Regular service pay, shown on recent payslips.
- A UK credit history, even if your recent address is overseas.
- A clear plan for the property, such as a family home you'll return to, or one you'll let.
- A deposit from a source they can verify, including any Forces Help to Buy loan.
Criteria change and aren't always published, which is where an adviser who has placed these cases before can save time.
Buying a home while posted overseas
Much of the process now happens by email, video call and e-signature, but a few steps need planning.
- Get advice and an agreement in principleChoose a lender that accepts your posting before a credit search is run.
- View and valueA partner, family member or video viewing can help. The lender will arrange its own valuation.
- Pass solicitor ID checksExpect certified documents or a digital ID check. Ask your solicitor early what they accept from overseas.
- Sign and completeSome documents need a witness or wet ink. Allow time for posting and plan around exercises or deployments.
Should you set up a power of attorney?
If you may be out of contact, some buyers give a trusted person power of attorney so they can sign on their behalf. A general power of attorney can cover a specific transaction. A lasting power of attorney for property and financial affairs is designed for the long term and takes several weeks to register with the Office of the Public Guardian. Lenders and solicitors each have rules on accepting attorneys, so ask them before you rely on one.
Buying your first home
Forces Help to Buy can still be used while overseas
If you're eligible, you apply through JPA as usual. Allow at least six weeks before completion. See our Forces Help to Buy service for the rules.
Remortgaging from abroad
Often simpler with your current lender
A product transfer with your existing lender usually avoids new address and income checks. Moving lender means passing full checks again. Our remortgage service can compare both.
Letting your UK home while you're posted
If you already own a home, a posting abroad doesn't have to mean selling. You can't simply move tenants in, though. Your lender needs to agree.
| Consent to let | Buy-to-let mortgage | |
|---|---|---|
| How it works | Your lender agrees to you letting the home on your current mortgage | You remortgage to buy-to-let, or buy a property to let |
| Suits | A posting of a set length when you plan to move back | Keeping the home as a long-term rental |
| Cost | Some lenders charge a fee or add to the rate; a number of large lenders have committed not to for posted personnel | Buy-to-let rates and fees, and the rent must cover the mortgage by the lender's margin |
Most buy-to-let mortgages are not regulated by the Financial Conduct Authority. Letting a former home can sometimes be regulated as consumer buy-to-let, depending on your circumstances.
Our military mortgages guide compares consent to let, let-to-buy and buy-to-let in more detail, and our buy-to-let service covers the lending side.
Tax on rent while you're overseas
Your service pay is normally still taxed in the UK while you're posted abroad. The Non-Resident Landlord Scheme works differently. HMRC's guidance says it depends on your "usual place of abode", not your tax residence, and applies to landlords living outside the UK for more than six months. That can include forces personnel on longer postings.
If it applies, your letting agent, or a tenant paying more than £100 a week, must deduct basic rate tax from the rent unless HMRC approves you to receive it gross. You apply for that on form NRL1, then report the income on your Self Assessment return. Check your position with HMRC or a tax adviser before the tenancy starts.
We are not tax advisers and this is not tax advice. What we say about the Non-Resident Landlord Scheme and tax on rent is a general summary based on the rules published at the time of writing, and we make no warranty about the tax you will pay. Speak to a qualified tax adviser or accountant about your own circumstances.

What does BFPO mean?
BFPO means British Forces Post Office. It's the MOD's postal service for armed forces personnel, their families and entitled staff serving overseas.
What is a BFPO address used for?
It lets post reach you wherever you're serving, using a BFPO number instead of a local address abroad. Mail goes via the UK, so it's addressed without a foreign town or country.
