For years, fixed rates have dominated the mortgage market. But with interest rates shifting and borrowers rethinking their options, Avant Money has introduced something new: the Avant Flex Mortgage.
This isn’t your standard variable rate. It’s a product designed to bring together the transparency of a tracker, the reassurance of a fixed rate, and the flexibility of a variable mortgage — all in one.
What Makes the Flex Mortgage Different?
At its heart, the Avant Flex is a variable mortgage, but with a twist:
- The benchmark rate — the 12-month Euribor (a European interbank lending rate), updated once a year.
- A fixed margin — agreed when you take out your mortgage and locked in for the entire term.
Your repayments are based on these two elements. The benchmark can move annually, but your margin never changes — giving you clarity on exactly how your rate is made up.
Why Flex Works in Today’s Market
The timing of Flex’s launch couldn’t be better. In 2024, more than 20% of new mortgages were variable, a significant rise compared with less than 10% just two years earlier. This shift reflects growing borrower confidence as interest rates, after 18 months of steady decline, appear to be stabilising and may even continue to ease.
At the same time, the 12-month Euribor – which forms the benchmark for the Flex rate – is currently at a low level, allowing Avant to price this product very competitively. For borrowers, this means they can begin with lower monthly repayments while still enjoying the freedom to adapt later, whether that’s through making overpayments or moving to another product without penalties.
It is worth noting, however, that while Flex provides significant freedom, if you move away from the Flex Mortgage there is no guarantee you will be able to switch back to it in the future.
Key Features at a Glance
Here’s what the Avant Flex Mortgage offers:
-
Low starting rates: from 3.01% (for loans up to 80% loan-to-value) with an APRC of 3.08%. This helps keep monthly repayments lower compared to many fixed or variable rates.
-
12-month stability: your rate is fixed for 12 months at a time and only reviewed once a year, giving predictability and peace of mind.
-
Fixed margin for life: the margin is locked in from the start, so the only part that may change is the benchmark.
-
Freedom to overpay: you can make extra payments whenever you like, without penalties, helping you clear your mortgage faster and save on interest.
-
Switching flexibility: you can move to another Avant product in the future without any exit fees.
Understanding the Benchmark
The Flex Mortgage is linked to the 12-month Euribor. Avant Money publishes its benchmark rate monthly (on the 10th).
When you draw down your mortgage, the rate you pay is simply:
Benchmark rate at drawdown + your fixed margin = Your Flex rate
The margin never changes, while the Euribor may go up or down depending on the market. Because the Euribor is a public figure and only applied once a year to your mortgage, it’s easy to follow and transparent.
For example, from 10 September to 9 October 2025, the published Flex rates were:
-
For borrowers with loan-to-value of 80% or less: Benchmark 2.11% plus margin 0.90%, giving a total rate of 3.01% (APRC 3.08%). That’s about €5.55 per month for every €1,000 borrowed over 20 years.
-
For borrowers with loan-to-value over 80%: Benchmark 2.11% plus margin 1.10%, giving a total rate of 3.21% (APRC 3.28%). That’s about €5.65 per month for every €1,000 borrowed over 20 years.
Who Flex Could Work For
The Flex Mortgage may be a great option if you:
-
Want a lower starting rate than many fixed-term products.

Would struggle to manage if your repayments rose in the future.
How Flex Works Step by Step
- Apply through your broker or directly.
- Draw down your mortgage – at this point, your fixed margin is confirmed and combined with the current 12-month Euribor.
- First year – your repayments are fixed for 12 months.
- Annual reset – on your mortgage anniversary, the Euribor is updated and your repayments are recalculated.
- Flexibility throughout – you can make overpayments or switch to another Avant mortgage at any time without penalties.
FAQs
How often does my Avant Mortgage rate change?
Your Avant Flex Mortgage rate is reviewed once every 12 months on your mortgage anniversary. The 12-month Euribor benchmark may change, but your fixed margin never does.
Is the Avant Flex Mortgage always cheaper than fixed rates?
Not always. Avant Flex starts from some of the lowest available rates (from 3.01% for ≤80% LTV; APRC 3.08%), but repayments can rise if the 12-month Euribor increases. A fixed rate guarantees repayments for a longer period, while Flex prioritises flexibility and a lower starting rate.
Can I make overpayments on the Avant Flex Mortgage without penalties?
Yes. You can make lump-sum or regular overpayments at any time with no penalties. Overpaying can reduce the overall interest you pay and help you clear your mortgage sooner.
Can I switch away from Avant Flex later, and can I return to it?
You can switch from the Avant Flex Mortgage to another Avant product without an exit fee. However, availability of Flex can change, so there is no guarantee you will be able to switch back to Flex in the future.
Who is the Avant Flex Mortgage best suited for?
Flex suits borrowers who want a lower starting rate than many fixed products, value the ability to overpay or switch without fees, and are comfortable with some variability in repayments. It may be less suitable if you need guaranteed certainty for several years or would struggle with any increase in repayments.
Final Thoughts
The Avant Flex Mortgage is a timely and flexible choice, combining competitive pricing, repayment stability for 12 months at a time, and the freedom to adapt as your needs change. For homeowners finishing a fixed rate or switching from a higher-cost mortgage, Flex could be a smart alternative worth considering.
