Can a bank change my mortgage terms mid term?
A short answer, with the article it comes from.
The answer
Not without your written agreement. The circular forbids a lender to alter or vary your loan terms during the tenor unless you agree in writing, and a change to fees needs two months' notice.
CBUAE Circular 31/2013 Article 4, and CBUAE Consumer Protection Standards Clause 2.1.3.21, checked 2 October 2026.
Article 4 of the circular is plain: lenders "are not allowed to alter or vary terms and conditions of the loan or the facility during the tenor of the loan or the facility, unless agreed to in writing by the borrower". For commissions or fees it adds that "customers must be notified, at least, two months prior to implementation of such changes".
On a variable rate mortgage, the rate moving is not the bank changing your terms: it is your terms operating as written. When the benchmark, such as EIBOR, moves, your payment changes and the bank must tell you the new rate. When the bank raises the margin it adds to that benchmark, which it may do only where your contract permits a change, the Consumer Protection Standards require 30 calendar days' notice before the increase takes effect.
This is why the follow on margin is the number to look at rather than the headline rate. A low fixed period attached to a wide margin afterwards can cost more over the life of the loan than a higher opening rate with a tighter margin, and the difference is not visible on a comparison table that shows only the first number.
We hold the follow on margin for every product on our panel, so if you want yours checked against the market, or you have had a notice of a change, that is a straightforward thing to ask a specialist about.
Fee changes: two months' notice under Article 4. Margin increases: 30 calendar days' notice under Standards Clause 2.1.3.21.
Rules are the easy part. Your file is the question.
The regulation sets the ceiling. Which bank says yes, and on what terms, is what we do.
