About Chelsea Building Society's Legacy

Founded in 1875, Chelsea Building Society had a long and independent history, with a strong branch presence, particularly in London and the south of England. It grew significantly over the 20th century, merging with several smaller societies, including the City of London Building Society and the Catholic Building Society.

However, it was heavily impacted by the 2008 financial crisis, suffering losses from its exposure to failed Icelandic banks. This led to the merger with the larger Yorkshire Building Society in 2010, which was done to protect its members and ensure its stability.

What Happened to Chelsea Building Society Mortgages?

You can no longer apply for a new mortgage with Chelsea Building Society. All its assets and liabilities, including its entire mortgage book, were transferred to Yorkshire Building Society. If you have a Chelsea Building Society mortgage, your mortgage is now owned and administered by Yorkshire Building Society.

You are now a member of YBS, however, the Chelsea brand is maintained as an online and telephone-based service for existing customers. If your mortgage deal is ending, you can switch to a new "product transfer" deal under the Chelsea brand, but you cannot apply for a new mortgage or borrow more money.

New customers seeking a mortgage are directed to apply to its parent company, Yorkshire Building Society,

What were they known for?

Chelsea was known as a mutually owned lender who had a few key focus areas:

• Offset mortgages

• ‘Best buy’ rates that were highly competitive across the market

Which lenders can offer similar products?

While YBS is a direct replacement for Chelsea Building Society and has a broad offering which covers most of what they were known for, there are plenty of alternative lenders offering this type of deal across the market. For example:

• Offset mortgages - are more widely available than they once were, you could try: Coventry Buiding Society, Skipton Building Society or Barclays, all of whom offer this type of deal

• Best rates - Leeds Building Society and Nationwide Building Society are known for their aggressively competitive pricing, or you can check the latest mortgage rates across all lenders

If you’re looking to remortgage a legacy Chelsea mortgage it may be worth contacting YBS first to see if they offer preferential rates as an existing customer of their trading company.

Your options as an existing customer

If you hold an existing Chelsea Building Society mortgage, your account is actively administered by Yorkshire Building Society, granting you full access to YBS’s retention products and customer support services.

As an existing customer approaching the end of your current fixed, tracker, or discounted rate, you have several options to manage your mortgage without needing to remortgage to an external high-street lender:

• Switch Your Deal (Product Transfer): Before your current special rate expires and reverts to the Standard Variable Rate (SVR), you can complete a product transfer. YBS offers dedicated retention rates for existing Chelsea customers, allowing you to lock in a new fixed or tracker rate seamlessly. Because this is an internal switch, it typically requires no new legal work, no property revaluation fees, and no hard credit checks (provided you are not borrowing more).

• Borrow More (Further Advance): If you need to release equity for home improvements (such as an extension or energy-efficiency upgrades), debt consolidation, or a large personal purchase, you can apply for additional borrowing on your existing mortgage. You can borrow up to 85% of your home's current value (minimum £3,000 borrowing limit), with the new funds secured on a separate sub-account at a new interest rate, while keeping your primary mortgage intact.

• Move Home (Porting): If you are moving house but want to keep your current Chelsea/YBS mortgage deal, you can utilise the "porting" feature. This allows you to transfer your existing mortgage rate, balance, and terms to your new property. If the new home is more expensive, you can apply to borrow the difference on one of YBS’s current top-up rates.

• Change Borrowers (Transfer of Equity): Should your personal circumstances change due to marriage, separation, or a buyout, you can apply to add or remove a person from the mortgage deeds. This process is subject to a full YBS affordability assessment for the remaining or new borrowers to ensure the debt can still be serviced.

• Make Overpayments: If you want to pay down your mortgage faster, existing customers can typically overpay up to 10% of their outstanding mortgage balance each calendar year without triggering Early Repayment Charges (ERCs). Overpaymentscan be made as regular monthly top-ups or single lump sums, directly reducing the capital balance and the amount of interest charged.

• Payment Recalculation: If you are currently on a Standard Variable Rate (SVR) or a Bank of England Base Rate Tracker, you can request a manual payment recalculation whenever the base rate changes. This ensures your monthly payments remain accurately aligned with your target mortgage end date.
