Following the merger on 1st April 2010, we became part of the YBS Group, one of the largest Building Societies in the UK. Our business is built on strong values and we have a long standing culture of giving our customers fair treatment.

You can read more about how Chelsea Building Society was founded and our merger with the YBS Group on our history page.

As a building society we don't need to answer to external shareholders. Our priority is and always will be with our members - people like you who've taken out one of our savings or mortgage accounts.

What's more, our merger with Yorkshire Building Society means that you can trust Chelsea to look after your money. While you continue to enjoy all the advantages of Chelsea's high quality personal service, not to mention a range of accounts designed to suit your needs, behind the scenes you'll benefit from the added support of an organisation with assets of over £30 billion.

Our Purpose

We’ve built our strategy around our purpose of providing Real Help with Real Life. For us, as a building society, it means delivering three central ambitions: helping people to have a place to call home and helping them towards greater financial wellbeing, whilst creating long-term value for our members. You can find out more about strategy and what we’re doing on our Your Society page.


Our values

Our values help to build a culture of fairness in all our dealings with customers, our staff and the wider community. We aim to live by these values in everything we do, ensuring that we give you the best experience we possibly can.

We are passionate about success
Act with integrity and respect
Strive to deliver quality and excellence
Value people as individuals

Treating customers fairly

We believe in providing good value, transparent products and a professional, efficient service. We also believe in treating all our customers fairly and we make sure we do this by:

Having well trained, competent and professional staff
Encouraging all our staff to embrace our core values in their behaviour
Providing products and services that meet the needs of our customers
Keeping our customers properly informed before, during and after they take a financial product with Chelsea
Complying fully with the letter and spirit of all relevant legislation, regulations and codes of practice
Insisting that all our advertisements and promotions are clear, fair and not misleading
If things go wrong, handling complaints fairly, promptly and impartially
Monitoring how we're doing through comprehensive measures and controls


When a customer takes out a savings or mortgage product with us, they become a member of our society – a mutual society, run for them and where they really matter. This is because our members are our owners.

As a mutual society, we don't have external shareholders to take profit out of the business. This means we're different to banks. We aim to make sufficient profit to maintain our financial strength and reinvest for our future, rather than paying out to shareholders. Our focus is on our members – putting them, not shareholders, at the heart of everything we do.

As we are owned by our members, if eligible they get to vote on key decisions at our Annual General Meeting (AGM) - such as election of the directors who run the Society on their behalf. We also regularly ask our members for feedback so we can be even better at meeting their needs.
