Tracker vs Fixed
Best Tracker vs Fixed Rate Mortgage: March 2026 Head-to-Head Comparison
Halifax's 3.96% tracker sits 0.56% below NatWest's leading 2-year fixed rate at 4.52%, offering potential monthly savings of £76 on a £250k mortgage. We analyse which product delivers better value and suits different borrower types in today's evolving rate environment.
With mortgage rates showing signs of stabilisation in early 2026, borrowers face a classic dilemma: lock into certainty with a fixed rate or gamble on potential savings with a tracker mortgage. Today's market presents a particularly interesting scenario, with Halifax's best tracker at 3.96% sitting significantly below NatWest's leading 2-year fixed rate at 4.52%.
This 0.56 percentage point gap represents the largest differential we've seen between tracker and fixed rates since late 2023, making the choice more compelling than it has been for some time.

The Numbers: Worked Example
Let's examine how these products perform with a typical £250,000 mortgage over 25 years:
Halifax Tracker (3.96%):
- Monthly payment: £1,302
- Total cost over 2 years: £31,248
- Arrangement fee: £999
- Total cost including fee: £32,247
NatWest 2-Year Fixed (4.52%):
- Monthly payment: £1,378
- Total cost over 2 years: £33,072
- Arrangement fee: £995
- Total cost including fee: £34,067
The tracker delivers savings of £76 monthly (£912 annually), resulting in total savings of £1,820 over the initial two-year period if base rates remain unchanged.
The Base Rate Breakeven Point
The current base rate of 3.75% would need to rise to approximately 4.27% for the tracker to match the fixed rate's monthly cost. This represents a 0.52 percentage point increase from current levels.
Given that Halifax's tracker sits at Base Rate + 0.21%, any base rate above 4.31% would make the fixed rate cheaper on a monthly basis. However, even a rise to 4.50% base rate (tracker rate of 4.71%) would only result in additional costs of around £200 over two years compared to staying fixed.
The real risk emerges if base rates climb above 5%, pushing the tracker beyond 5.21% and creating monthly payments exceeding £1,450 - over £70 more than the fixed rate option.
Market Context and Rate Outlook
The Bank of England's Monetary Policy Committee next meets on 6th May 2026, with many economists expecting rates to hold steady following the recent period of economic stabilisation. The current 3.75% base rate represents the committee's assessment of appropriate monetary policy given inflation trends and economic growth.
However, the mortgage market has priced in some uncertainty. The 0.77 percentage point premium that NatWest's 2-year fixed rate commands over the base rate suggests lenders expect some upward pressure on rates over the next 24 months.
Comparing this to NatWest's 5-year fixed rate at 4.69%, we see an additional 0.17 percentage points for three extra years of certainty - relatively modest pricing that suggests the long-term outlook remains fairly stable.
Risk vs Reward Analysis
The tracker mortgage offers immediate savings but exposes borrowers to interest rate risk. Based on current pricing, base rates could rise by up to 0.5 percentage points before eroding the tracker's advantage entirely.
Historical data shows that base rate cycles tend to move in 0.25% increments, meaning two rate rises would bring the costs roughly level. Three rises (0.75% total) would make the fixed rate clearly superior.
Conversely, any base rate cuts would enhance the tracker's advantage. A reduction to 3.50% would push the tracker rate to 3.71%, creating monthly savings of over £100 compared to the fixed rate.
Borrower Suitability
The tracker mortgage suits:
- Risk-tolerant borrowers comfortable with payment variability
- Those with sufficient income headroom to absorb potential rate rises
- Borrowers expecting base rates to remain stable or fall
- First-time buyers maximising affordability in the short term
- Those planning to remortgage or move within 18-24 months
The fixed rate mortgage suits:
The Verdict
Halifax's tracker mortgage offers compelling value at current rates, providing immediate monthly savings of £76 and total savings approaching £2,000 over two years if base rates hold steady.
For borrowers with adequate financial headroom and tolerance for rate variability, the tracker presents an attractive proposition. The relatively modest base rate rises needed to equalise costs mean the downside risk is manageable for most households.
However, NatWest's fixed rate provides valuable certainty in an uncertain economic environment. The premium paid for this security - around £900 annually - represents reasonable insurance against potential rate volatility.
The choice ultimately depends on your risk tolerance and financial circumstances. Those comfortable with some uncertainty should seriously consider the tracker's current value, while borrowers prioritising budgeting certainty will find the fixed rate worth its premium.

Frequently Asked Questions
How do tracker mortgages work and when do rates change?
Tracker mortgages follow the Bank of England base rate plus a fixed margin. Halifax's current tracker is Base Rate + 0.21%, so with base rate at 3.75%, you pay 3.96%. When the MPC changes base rate (typically every 6-8 weeks), your rate adjusts automatically, usually within one month. Most lenders apply changes from the first day of the following month after a base rate announcement.
What are early repayment charges (ERCs) on these mortgages?
NatWest's 2-year fixed rate typically carries ERCs of around 2% in year one and 1% in year two if you repay early. Halifax's tracker mortgage usually has no ERCs after an initial period (often 6-12 months), giving you more flexibility to switch or repay without penalty. Always check specific product terms as these can vary between lenders and products.
What's the outlook for Bank of England base rates in 2026?
Most economists expect base rates to remain relatively stable around 3.5-4% through 2026, following the recent period of economic stabilisation. The next MPC meeting is 6th May 2026. While no one can predict with certainty, the mortgage market's pricing suggests modest upward pressure over the next 2 years, with long-term rates indicating eventual stabilisation.
When should I choose fixed rate over tracker mortgages?
Choose fixed rates when you need payment certainty, are stretched on affordability, or expect significant base rate rises. Fixed rates suit risk-averse borrowers, those with tight budgets, or variable income households. Pick trackers when you can absorb payment increases, expect rates to remain stable or fall, or want to maximise short-term affordability with tolerance for rate risk.
At what base rate level would the tracker become more expensive?
Halifax's tracker (Base Rate + 0.21%) would exceed NatWest's 4.52% fixed rate when base rate reaches approximately 4.31%. This represents a 0.56 percentage point rise from the current 3.75% level. Even then, the difference would be modest initially - significant cost increases only emerge if base rate climbs above 5%, pushing the tracker beyond 5.21%.
