Citi Bank mortgage rates vs high street bank mortgage rates.
Citi Private Bank (UK branch) provides tailored financing to ultra-high-net-worth (UHNW) clients worldwide — including for the UK.
The bank offers Customised home financing (fixed, adjustable, interest-only, multi-currency, portfolio-backed). There is no formal mortgage maximum loan cap but to qualify typically you’ll need at least US $10 million AUM and a net worth above US $25 million.
In the UK mortgage market there has been an ongoing price war as lenders look to attract wealthier clients and issue more £1 million+ mortgages. The most competitively priced mortgage rates start from 3.75% and there are variable rates without tie-ins that track the Bank of England base rate plus 0.1%.
Aaron Strutt, product director at Trinity Financial, says: "There are lots of banks and building societies keen to ramp up their lending volumes and there is competition between the lenders. More borrowers are also remortgaging to get better rates or raise additional funds for home improvements or to gift cash to their adult children.
"There are well over 75+ banks and building societies offering mortgages of £1 million or more in the UK, often with different rates, arrangement fees, deposit requirements, and affordability calculations to determine how much people can borrow. Many can accept an application from a borrower paid in a foreign currency such as the euro or the dollar."
Alternative mortgage lenders for most borrowers
If you don’t meet Citi’s UHNW threshold or require a straightforward residential mortgage, traditional UK mortgage lenders such as Santander UK, HSBC, Barclays for Intermediaries, NatWest, or specialist private mortgage banks may well be more suitable. They offer:
- Offer standard large mortgages (£300,000k–£10m+).
- Competitive fixed- and variable-rate options starting below 4%.
- Transparent, faster processes and lower fees.
- No need for huge AUM or complex underwriting.
Do you want a mortgage in the UK?
Citi Private Bank could be an option — only if you’re in the UHNW bracket and maintain a global relationship with Citi. Otherwise, your best route is a high-street or private mortgage lender that specialises in large or unique cases but services a broader audience. Trinity Financial's brokers will assess the market on your behalf.
What types of properties do the high-net-worth lenders provide mortgages for?
Mortgage lenders can assist with financing for:
- Prime residential properties.
- Luxury second homes - often by the sea.
- Buy-to-let investments for clients with a professional portfolio, potentially overseas.
- Unique or high-value properties requiring tailored financing.
- Self-build mortgages.

Interest-only mortgages are popular with high-net-worth individuals and are constantly provided by private banks. These mortgages may help borrowers free up cash for other investments, businesses, or family members.
Most private banks offer interest only. Some private banks can issue interest-only mortgages up to 90% of the property value or through part and part mortgages where some of the loan is on capital repayment.
