AIB Mortgage Review Ireland 2026: Rates, Service & Features

AIB (Allied Irish Banks) holds the largest share of Ireland’s mortgage market, lending to roughly one in three homebuyers. That market dominance doesn’t automatically make them the best choice for your specific circumstances, but it does mean they’ve got the scale, digital infrastructure, and product range worth examining closely.

This review covers what you actually need to know about getting a mortgage from AIB in 2026: their current rates, how the application process works, what switchers can expect, and where they stand compared to other Irish lenders.

AIB Mortgage Rates 2026

AIB operates a tiered rate structure where new customers generally get better deals than existing customers. This pricing strategy is standard across Irish banks but frustrates borrowers who’ve been loyal for years.

Current Rate Structure

These rates reflect the September 2026 market where ECB base rates have fallen from their 2023 peak. AIB adjusted their fixed rates downward in July 2026, following similar moves by Bank of Ireland and Permanent TSB.

Green Mortgage Discount

AIB offers a 0.15% discount on fixed rates for properties with a Building Energy Rating (BER) of A or B. The discount applies for the fixed rate period, so a standard 2.85% rate becomes 2.70% for a qualifying property.

You’ll need to provide your BER certificate during the application. If you’re buying new build, the builder should supply this. For existing homes, the Energy Performance Certificate from the estate agent usually covers it.

Switcher Offers and Cashback

AIB positions itself aggressively in the mortgage switching market, which makes sense given their need to maintain market share.

2026 Cashback Structure

• €100,000-€249,999 mortgage balance: €1,500 cashback
• €250,000-€499,999 mortgage balance: €2,000 cashback
• €500,000+ mortgage balance: €3,000 cashback

The cashback gets paid into your current account within 90 days of drawdown. There’s no clawback period, meaning you can switch again immediately if a better deal appears, though that strategy has its own costs (legal fees, valuation).

Legal Fees

AIB covers your legal fees up to €1,500 when switching to them. This typically covers a straightforward switch, but complex cases (multiple property titles, historical planning issues) might exceed that cap.

Valuation

They also cover the property valuation cost, which runs €150-200 depending on your area. Some banks charge this upfront then reimburse; AIB handles it directly with their panel valuers.

Application Process

AIB has invested heavily in digital mortgage applications, and it shows. The process is genuinely online, not just digital forms that still require branch visits.

Getting Started

You’ll need to register on the AIB mortgage portal. Create an account, answer preliminary questions about income and property, and the system estimates what you might borrow based on Central Bank rules.

The portal walks you through document upload: payslips, P60, bank statements, identification. The interface is clearer than some competitors, with progress tracking that actually reflects where your application stands.

Documentation Requirements

Standard documentation for employed applicants:

• Three months’ consecutive payslips
• P60 for the most recent tax year
• Six months’ bank statements (all accounts)
• Photo ID (passport or driving licence)
• Proof of address (utility bill within three months)
• Property details (Eircode, BER, survey if available)

Self-employed applicants need three years’ audited accounts plus Revenue correspondence. AIB is reasonably accommodating with self-employed income but follows standard banking practice of averaging recent years and applying stress tests.

Approval in Principle

Submit a complete application and you’ll typically get Approval in Principle (AIP) within five working days. This isn’t a guarantee, but it’s enough to show estate agents you’re serious and gives you a clear borrowing limit for house hunting.

The AIP is valid for six months. If your circumstances change (new job, salary increase, additional debt), tell AIB immediately as it affects your final approval.

From AIP to Loan Offer

Once you’ve identified a property and had an offer accepted, you move to full approval. This is where AIB conducts the property valuation, checks the title, and issues a formal loan offer.

Timeline is usually 2-3 weeks for straightforward cases. Delays happen when there are property issues (boundary disputes, planning permission questions) or when your documentation needs clarification.

Customer Service and Support

AIB’s customer service reputation sits in the middle range among Irish lenders. They’re neither outstanding nor terrible, which is perhaps expected for a large institution.

Branch Network

AIB maintains an extensive branch network across Ireland, which matters if you prefer face-to-face meetings. Most mortgage discussions can happen via phone or video call, but some people want to sit across a desk from someone when borrowing €300,000.

Digital Communication

The mortgage portal includes secure messaging with your assigned mortgage team. Response times are generally within 24-48 hours for non-urgent queries. Phone support is available during business hours, with typical wait times of 5-15 minutes.

Dedicated Mortgage Teams

Rather than dealing with generic call centre staff, AIB assigns your application to a specific mortgage team. You get direct contact details and can usually reach the same person throughout the process. This continuity helps, especially when questions arise about documentation or property issues.

First-Time Buyer Experience

AIB actively pursues first-time buyer business and offers several features targeting this market.

90% LTV Availability

AIB lends up to 90% LTV for first-time buyers, following Central Bank rules. This means a 10% deposit on properties up to €500,000. Above that threshold, you’ll need 20% for the portion exceeding €500,000.

Help to Buy Integration

The application process accommodates the Help to Buy scheme, which provides a tax rebate up to €30,000 for first-time buyers of new builds. AIB’s systems understand how Help to Buy affects your deposit and can factor the expected rebate into loan calculations.

First-Time Buyer Support

AIB runs regular first-time buyer webinars and provides online guides. These are basic but useful if you’re completely new to mortgages. The content covers Central Bank rules, what documents you need, and how to use their affordability calculator.

Fixed vs Variable Options

AIB’s fixed rate offering is more competitive than their variable rates, which is standard across Irish banks in 2026.

Fixed Rate Terms

AIB offers fixed rates from 2 to 10 years. The most popular choices are 3 and 5 years. Longer terms (7-10 years) carry rate premiums but provide extended certainty.

If you fix for three years at 2.85% and rates fall further, you’re locked in unless you pay break fees. If rates rise, you’re protected. Given current ECB trajectory (rates falling from 2023 peak), short to medium fixed terms make sense for most borrowers.

Standard Variable Rate

At 3.95%, AIB’s standard variable rate is more than a full percentage point above their best fixed rates. There’s no compelling reason to choose variable unless you specifically want flexibility to overpay without restriction or plan to sell within 1-2 years.

Switching Fixed Terms

When your fixed period ends, AIB moves you to their standard variable rate unless you actively choose a new fixed term. This is a common frustration: your rate jumps significantly, making it the perfect time to either fix again with AIB or switch to a competitor.

Set a calendar reminder for 3-4 months before your fixed term expires. This gives you time to review the market, compare offers, and negotiate with AIB or begin a switch to another lender.

Overpayments and Flexibility

AIB allows overpayments up to 10% of your mortgage balance annually without penalty on fixed rate mortgages. This flexibility helps if you receive a bonus, inheritance, or other lump sum and want to reduce your mortgage faster.

Overpayments above 10% trigger break fees on fixed rates. The calculation considers the interest rate difference between your fixed rate and current market rates. If rates have fallen since you fixed, the break fee can be substantial.

Variable rate mortgages allow unlimited overpayments without penalty, which is their main advantage over fixed rates.

Fees and Charges

AIB’s fee structure is straightforward:

• Application fee: €150 (non-refundable)
• Valuation fee: €150-200 (covered for switchers)
• Legal fees: Your solicitor’s costs (covered up to €1,500 for switchers)
• Land Registry fees: Statutory fees, typically €400-700

There’s no ongoing annual management fee, which some smaller lenders charge.

Mortgage Protection Insurance

You must have mortgage protection insurance (life cover that pays off the mortgage if you die) to draw down an AIB mortgage. This is a Central Bank requirement, not an AIB policy choice.

AIB offers their own mortgage protection but you’re not obliged to use it. Shop around among life insurance providers as rates vary. Many people get better value using a broker to compare multiple insurers.

The premium depends on your age, health, whether you smoke, and loan term. Budget roughly €25-50 monthly for a non-smoker in their 30s borrowing €300,000 over 30 years.

How AIB Compares to Other Lenders

Rate Competitiveness

AIB’s new customer rates are competitive but not always the cheapest. Avant Money and Finance Ireland often undercut them by 0.10-0.20%. However, AIB’s established status and full banking services appeal to borrowers who want everything in one place.

For existing customers on standard variable rates, AIB is expensive. You’ll almost certainly save money by switching to any other lender, including back to AIB as a “new” customer after a cooling-off period.

Digital Experience

AIB’s online mortgage application is among the best in Ireland, comparable to Bank of Ireland and ahead of some smaller lenders still using paper-heavy processes. The portal is intuitive and the document upload system works reliably.

Market Position

Being Ireland’s largest mortgage lender brings advantages: established processes, extensive branch network, and strong financial stability. It also means AIB can be less aggressive on pricing for existing customers, knowing inertia keeps many people from switching.

Potential Drawbacks

Existing Customer Rates

The gap between new customer and existing customer rates is significant. If you got your AIB mortgage three years ago and are now rolling off a fixed term, their standard variable rate will shock you. This rate structure encourages constant shopping around rather than loyalty.

Processing Speed Variation

While AIB quotes 5 days for AIP and 2-3 weeks for loan offers, these timelines can stretch when they’re busy or documentation issues arise. Some applicants report faster service; others face delays. Much depends on your assigned team and application complexity.

Break Fees

AIB’s fixed rate break fees follow the standard industry formula but can be opaque. Getting a clear break fee calculation before committing to break your fixed term requires contacting them directly, and the fee can change daily based on interest rate movements.

Who Should Consider AIB?

AIB makes sense for:

• Switchers with substantial mortgages: The cashback and rate combination works well if you’re switching €250,000+
• First-time buyers wanting full-service banking: If you prefer consolidating your current account, mortgage, and other banking with one institution
• Borrowers valuing digital convenience: The online application process is genuinely good
• Green property buyers: The BER discount adds value if you’re buying an energy-efficient home

AIB might not be ideal for:

• Existing AIB mortgage customers on variable rates: You’ll save significantly by switching out
• Borrowers seeking absolute lowest rates: Avant and others occasionally undercut AIB
• Self-employed with complex income: While AIB accepts self-employed applicants, some brokers report better outcomes with lenders who specialize in non-standard cases

The Broker Question

You can apply to AIB directly or through a mortgage broker. Direct application makes sense if you’ve researched rates, understand your borrowing capacity, and want to manage the process yourself.

A broker adds value if you want rate comparison across multiple lenders, have complex income (self-employed, contractor), or need help navigating documentation requirements. Brokers often secure better rates than standard published rates through lender relationships.

Most brokers don’t charge borrowers (they’re paid commission by lenders), so there’s minimal downside to getting a broker’s opinion even if you ultimately apply directly.

Final Assessment

AIB offers a solid mortgage product with competitive rates for new customers, good digital infrastructure, and the reassurance of Ireland’s largest lender. They’re not always the cheapest option, but they’re rarely the most expensive either.

The key is understanding where you fit: new customers and switchers get good deals; existing customers pay significantly more. If you’re already with AIB and your fixed term is ending, treat yourself as a new customer in the market rather than accepting whatever rate they offer to stay.

Compare AIB’s current offer against at least two other lenders. Look at the effective rate after cashback, factor in any fees you’ll actually pay, and consider the service experience based on online reviews and recommendations from people who’ve recently completed the process.

For many Irish borrowers, AIB represents a safe, middle-ground choice. Not the most exciting, not the most innovative, but reliable and functional with enough competitive edge to make the shortlist.
