Tracker vs Fixed
Tracker vs Fixed: The £1,680 Question Every Homebuyer Must Ask in March 2026
Halifax's 3.96% tracker undercuts NatWest's 4.52% fixed rate by £70 monthly on a £250k mortgage. We analyse whether the £1,680 two-year saving justifies the base rate risk, and reveal which borrowers should choose each option.
The Current Mortgage Landscape: A Clear Winner on Paper
In today's mortgage market, the numbers tell a compelling story. Halifax's best tracker mortgage sits at 3.96% (£999 fee), undercutting NatWest's leading 2-year fixed rate of 4.52% (£995 fee) by a substantial 0.56 percentage points.
With the Bank of England base rate currently at 3.75%, this tracker sits just 0.21% above base rate – a historically tight margin that reflects intense competition among lenders. But raw rates only tell part of the story.
The £250,000 Reality Check: Monthly Payments Breakdown
Let's examine what these rates mean for a typical £250,000 mortgage over 25 years:
Halifax Tracker (3.96%)
- Monthly payment: £1,322
- Total paid over 2 years: £31,728
- Arrangement fee: £999
- Total cost over initial 2 years: £32,727
NatWest 2-Year Fixed (4.52%)
- Monthly payment: £1,392
- Total paid over 2 years: £33,408
- Arrangement fee: £995
- Total cost over initial 2 years: £34,403
The tracker delivers immediate savings of £70 per month, totalling £1,680 over the two-year comparison period. However, this advantage exists only if base rates remain stable or fall.
The Base Rate Tipping Point Analysis
The critical question becomes: at what point does the tracker become more expensive than the fixed rate?
Currently, the Halifax tracker sits at base rate + 0.21%. For it to match NatWest's 4.52% fixed rate, the Bank of England base rate would need to rise to 4.31% – an increase of 0.56 percentage points from today's 3.75%.
This represents a significant buffer. Even a quarter-point rise to 4.00% would only push the tracker to 4.21%, maintaining a 0.31% advantage over the fixed rate.
Economic Context and Rate Expectations
The current rate environment reflects a period of relative monetary policy stability. With base rate at 3.75%, the Bank of England appears to be in a holding pattern, balancing inflation concerns against economic growth needs.
Market pricing suggests traders expect rates to remain broadly stable over the coming months, though geopolitical uncertainties and inflation pressures could shift this outlook quickly.
Beyond the Numbers: Practical Considerations
Flexibility and Features
Both products offer competitive terms, but tracker mortgages typically provide greater flexibility. Most tracker deals allow unlimited overpayments and often carry lower early repayment charges, making them attractive for borrowers who value payment flexibility.
Budgeting Implications
The £70 monthly difference represents real money for household budgeting. Over two years, this £1,680 saving could fund home improvements, reduce other debts, or provide additional financial breathing room.
However, tracker borrowers must budget for potential payment increases. A borrower comfortable with the current £1,322 payment should consider whether they could manage increases to £1,400+ if rates rise significantly.
Risk Assessment: Who Should Choose What
Tracker Mortgage Suits:
- Borrowers with financial flexibility to absorb payment increases
- Those who believe rates will remain stable or fall
- Homeowners planning to overpay or potentially move within 2-3 years
- Risk-comfortable borrowers seeking immediate savings
Fixed Rate Suits:
- First-time buyers operating on tight budgets
- Households where payment predictability is crucial
- Borrowers expecting major life changes (career transitions, growing families)
- Those who would struggle with payment increases above current fixed rates
The Long-Term Perspective
While the 2-year comparison favours the tracker, borrowers should consider their longer-term strategy. NatWest's 5-year fixed rate at 4.69% offers extended certainty, though at a higher cost than either 2-year option.
The mortgage comparison becomes more complex when factoring in remortgaging costs and market conditions in 2-5 years' time.
Our Verdict: A Calculated Risk Worth Taking
For suitable borrowers, Halifax's tracker mortgage presents compelling value. The 0.56% rate advantage provides substantial immediate savings, while base rate would need to rise significantly to eliminate this benefit.
However, this recommendation comes with important caveats. Tracker mortgages require financial resilience and comfort with uncertainty. Borrowers must honestly assess their ability to handle payment increases of £50-100 monthly if rates rise.
The current rate differential suggests lenders expect base rate stability, making the tracker an attractive proposition for confident borrowers. Those requiring payment certainty should stick with fixed rates despite the current cost penalty.

Frequently Asked Questions
How quickly do tracker mortgage payments change when base rate moves?
Most tracker mortgages adjust immediately when the Bank of England changes base rate, typically taking effect from your next monthly payment date. Halifax's tracker follows base rate movements precisely, so a 0.25% base rate rise would increase your monthly payment by approximately £33 on a £250,000 mortgage.
Can I switch from a tracker to fixed rate without penalty?
Generally no – switching mortgage products early triggers early repayment charges (ERCs), typically 1-3% of the outstanding balance in the first few years. However, many lenders allow you to switch to their other products without ERCs, though you'll likely pay arrangement fees. Always check your specific terms before switching.
What's the maximum base rate rise I should prepare for with a tracker?
While impossible to predict precisely, financial resilience planning suggests budgeting for at least 1-2% base rate rises over a 2-3 year period. This would increase monthly payments by roughly £130-260 on a £250k mortgage. If such increases would cause serious financial strain, fixed rates offer better security.
Are tracker mortgages always cheaper than fixed rates historically?
No – tracker mortgages can become expensive during rising rate cycles. Between 2004-2007, base rate rose from 4% to 5.75%, making many trackers more expensive than available fixed rates. The key advantage of trackers is they also fall when rates drop, as seen during 2008-2016 when base rate fell to historic lows.
Should I fix now if I think rates will rise this year?
If you genuinely expect significant base rate rises (0.5%+ over 6-12 months), fixing makes financial sense. However, timing rate movements is notoriously difficult. Consider your personal financial resilience first – if you can comfortably handle payment increases, the current tracker rate advantage may outweigh potential future rises.
