Tracker vs Fixed
Tracker vs Fixed Mortgages: March 2026 Battle of the Rates
March 2026 sees Halifax's tracker mortgage at 3.96% significantly undercutting NatWest's 4.52% fixed rate. Our analysis reveals monthly savings of £76 on a £250,000 mortgage, but which product offers better long-term value depends on your risk appetite and rate expectations.
The Current Mortgage Landscape
March 2026 presents borrowers with an interesting dilemma. The mortgage market is offering a rare scenario where tracker mortgages are significantly undercutting fixed-rate deals, creating genuine savings for those willing to accept variable rates.
With the Bank of England base rate sitting at 3.75%, the best tracker mortgage from Halifax at 3.96% carries just a 0.21% margin above base rate. Meanwhile, NatWest's leading 2-year fixed rate sits at 4.52% — a substantial 0.56% premium over the tracker option.
Head-to-Head: The Numbers That Matter
Let's examine the standout products dominating today's best-buy tables:
- Best Tracker: Halifax 3.96% (£999 fee)
- Best 2-Year Fixed: NatWest 4.52% (£995 fee)
- Best 5-Year Fixed: NatWest 4.69% (£995 fee)
The tracker's advantage is immediately apparent, but the true cost difference becomes clearer when we examine real-world scenarios.
Real-World Cost Analysis: £250,000 Mortgage
For a typical £250,000 mortgage over 25 years at 60% LTV, here's how the monthly payments compare:
Halifax Tracker (3.96%)
- Monthly payment: £1,323
- Total cost over 2 years: £32,751 (including £999 fee)
NatWest 2-Year Fixed (4.52%)
- Monthly payment: £1,399
- Total cost over 2 years: £34,571 (including £995 fee)
NatWest 5-Year Fixed (4.69%)
- Monthly payment: £1,423
- Total cost over 5 years: £86,375 (including £995 fee)
The tracker delivers immediate monthly savings of £76 compared to the 2-year fix, totalling £1,820 over the initial two-year period. Against the 5-year fix, monthly savings reach £100.
The Base Rate Breakeven Point
The critical question for tracker borrowers: at what point does the base rate movement eliminate the current advantage?
With Halifax's tracker at base rate plus 0.21%, the rate would match NatWest's 2-year fix if the Bank of England raised rates to 4.31% — a significant 0.56% increase from today's 3.75%.
For context, such a move would represent one of the more aggressive tightening cycles in recent memory, requiring multiple consecutive rate rises or a substantial single adjustment.
Market Timing and Rate Expectations
The current base rate of 3.75% reflects the Bank of England's ongoing battle with persistent inflation pressures. The next Monetary Policy Committee decision looms, with markets pricing in a relatively stable environment despite global economic uncertainties.
Tracker borrowers benefit immediately from any rate cuts, while fixed-rate customers gain protection against increases. The 0.56% cushion currently favouring trackers provides substantial room for rate rises before the products reach parity.
Risk Assessment: Who Wins?
Tracker Mortgages Suit:
- Borrowers comfortable with payment variability
- Those expecting base rates to fall or remain stable
- Customers seeking maximum flexibility without early repayment charges
- Borrowers with sufficient income buffer for potential rate rises
Fixed Mortgages Suit:
- Customers prioritising payment certainty
- Those stretched on affordability at current rates
- Borrowers expecting significant rate increases
- First-time buyers wanting predictable budgeting
The Flexibility Factor
Beyond rate considerations, tracker mortgages typically offer superior flexibility. Halifax's tracker avoids early repayment charges, allowing borrowers to switch or overpay without penalty. NatWest's fixed products carry standard ERCs during the initial term, potentially costing thousands for early exit.
This flexibility proves valuable for borrowers anticipating life changes, property moves, or opportunities to remortgage to better deals.
Lender Strength and Service Quality
Both Halifax and NatWest represent established, reliable lenders with strong market positions. Halifax's recent competitive tracker pricing reflects their push for market share, while NatWest's fixed-rate leadership demonstrates their commitment to certainty-seeking borrowers.
Service levels and processing times remain comparable between both institutions, removing lender quality as a differentiating factor in this comparison.
The Verdict: March 2026
The current mortgage market heavily favours tracker products for borrowers comfortable with rate variability. Halifax's 3.96% tracker offers compelling value, providing immediate monthly savings of £76 compared to the best 2-year fix.
The substantial 0.56% rate advantage creates a significant buffer against base rate increases. Even aggressive monetary policy tightening would need to push rates above 4.31% before the tracker becomes more expensive than today's best fixed rate.
For risk-tolerant borrowers with stable incomes, the tracker represents excellent value in the current environment. However, those prioritising payment certainty or operating with tight budgets may find the fixed-rate security worth the premium.

Frequently Asked Questions
How exactly do tracker mortgages work and when do payments change?
Tracker mortgages follow the Bank of England base rate plus a fixed margin (Halifax's is base rate + 0.21%). When the BoE changes rates, your mortgage rate adjusts automatically, typically within one month. Payment changes usually take effect from the next monthly payment date, with lenders required to give advance notice of the new amount.
What are early repayment charges and how do they differ between trackers and fixed rates?
Early repayment charges (ERCs) are fees for paying off or switching your mortgage during the initial deal period. Halifax's tracker typically has no ERCs, offering complete flexibility. NatWest's fixed rates usually carry ERCs of around 1-3% of the outstanding balance during the initial term, potentially costing thousands for early exit.
What's the current outlook for Bank of England base rates in 2026?
With base rates at 3.75%, the BoE faces ongoing inflation concerns while supporting economic growth. Market expectations suggest rates may remain relatively stable through 2026, though global economic pressures could prompt changes. The substantial 0.56% current advantage for trackers provides significant cushion against potential rate rises.
Should I choose a tracker if I'm a first-time buyer or have a tight budget?
First-time buyers and those on tight budgets should carefully consider payment stability. While trackers currently offer lower rates, payments can increase if base rates rise. If your budget couldn't accommodate a £50-100 monthly payment increase, the fixed rate's certainty may be worth the current premium despite higher initial costs.
Can I switch from a tracker to a fixed rate if I change my mind?
Yes, but timing and costs matter. With Halifax's tracker having no ERCs, you can remortgage to a fixed rate anytime, though you'll pay new arrangement fees and potentially higher rates than today's deals. It's worth monitoring rate movements and considering switches during your annual remortgage review rather than making hasty decisions.
