Choosing between Post Office Money and HSBC for your mortgage? Both are major UK lenders with competitive products. This guide compares their rates, eligibility criteria, fees, and who each lender suits best.
- Whole-of-market brokers see deals comparison sites don't carry, especially for non-standard income
- Loan-to-value bands (95/90/85/80/75%) drive pricing — check the nearest band boundary
- Get a soft-search decision in principle first — it costs nothing and reveals problems early
The Details That Decide Outcomes
Watch the fee, not just the rate. A £1,499 arrangement fee on a lower rate beats a fee-free deal only on larger loans — roughly £150,000+ for typical gaps. Below that, fee-free wins despite the higher headline rate.
Affordability rules changed materially after the 2022–23 rate cycle. Lenders now stress-test your payments at a notional higher rate, and your outgoings matter as much as income. Trimming commitments 3 months before applying genuinely increases what you can borrow.

Our Verdict

The only way to know which is truly cheaper is to compare your specific mortgage using a whole-of-market broker who can access both.
Frequently Asked Questions
What happens when my fixed rate ends?
You move to the lender's standard variable rate, which is almost always worse value. Most lenders let you lock a new deal up to 6 months ahead.
How long does a mortgage offer last?
Typically 3 to 6 months depending on the lender. New-build purchases often get extended validity because completion dates slip.
Will applying for a mortgage hurt my credit score?
A decision in principle usually uses a soft check, which doesn't affect your score. The full application is a hard check — which is why you should pick your lender before applying, not after.
What is loan-to-income and how much can I borrow?
Lenders cap borrowing at 4.49x income for most applicants. Professionals and higher earners can reach 5–6x with certain lenders.
How much deposit do I need for Post Office Money vs HSBC Mortgage — Which is Best in 2026??
The majority of lenders ask for at least 5–10% of the property price. A bigger deposit unlocks noticeably better rates — the biggest pricing jumps happen at 90%, 85% and 75% loan-to-value.
