Can Ecology Building Society change the interest rate?
We may change interest rates at any time if we reasonably believe that the change is needed for any of the following reasons (which may relate to circumstances existing at the time or those that are expected to apply in the near future):
• to respond to changes in the Bank of England Base Rate
• to respond to changes in mortgage or interest rates generally (including the interest rates paid on similar accounts by other providers of financial services)
• to enable us to manage the difference between the interest rates charged to our borrowers and interest rates paid to our investors, or the providers of funds to us, taking into account the interests of the Society, our members, and your rights and interests as an account holder
• to respond to changes in the law or the decision of a court or ombudsman
• to meet relevant regulatory requirements
• to respond to new (or changes to) statements or codes of practice or industry guidance designed to enhance consumer protection
• to reflect changes to our costs in providing the account, including administration costs and costs of providing services or facilities
• to introduce or alter ‘tiers’ of interest where different rates apply depending on the amount in the account.
Where we make any such change, we will act reasonably and we will only make the change if we believe it is fair in the circumstances.
Any change we make to interest rates will be proportionate to the circumstances giving rise to the change.
For further information regarding interest rate changes including the process for notifying you, please refer to section 7 in our leaflet Saving with Ecology – General terms and conditions.
What would the estimated balance be after 12 months based on a £1,000 deposit?
Based on a current interest rate of 0.45% gross, the balance on a £1,000 deposit after 12 months would be £1,004.50

Verifying identities helps protect us all from fraud
- We carry out identification requirements to protect everyone from fraud
- Where possible, we will first use electronic searches to confirm your identity
All banks, building societies and financial institutions are required by law to verify the identity of any individual or organisation that opens an account with them. This is necessary to protect the organisation, its members and the public from fraud and also to help combat money laundering.
You should note that there may be occasions when documentation over and above that stated here will need to be produced and you will be told if this applies to you.
What we need to verify an individual's identity
Existing member - quote your account number on your application:
If you already have an account with us and quote your account number on your application, we may not need any further evidence of your identity and address.
New to Ecology:
If you're new to Ecology, we'll verify your identity via electronic searches.
What we'll need if we request more information:
If we need more information, we'll ask you to provide us with two additional forms of identification, one from each of the tables (see below).

Joint account? You must each have your identity verified. However, both of you may rely on the same items from Table A and Table B if they are addressed to and clearly identify each of you.
Please note:
- Online statements or downloaded documents cannot be accepted under any circumstances
- Any documents produced must be current and issued within the last 12 months
- The identification provided must be from different organisations
- All original documents will be returned to you when the account has been opened

Copies of passports and driving licences must be certified by one of the following:

Certification: The document that is being certified must state 'original seen' as well as being dated and signed. The document should also include the name of the certifier, their profession and full contact details. If the identification is photographic, the certifier must state that 'the photograph is a good likeness of the applicant'. The certifier must not be related to the applicant in any way, or named as a joint account holder.
