What Makes a Tracker Mortgage "Cheap"?
A cheap tracker mortgage isn't just about the headline rate. It's determined by the margin above the Bank of England base rate, which is the only part you can control through your borrowing profile.
Key Factors for Cheap Tracker Rates:
Lower LTV = Lower Margin
60% LTV trackers are typically 0.25-0.50% cheaper than 90% LTV deals. Every 5% more deposit can save 0.10-0.15% on your margin.
Lifetime Trackers Often Cheapest
Lifetime trackers typically offer margins 0.25% lower than 2-year trackers, though you're exposed to rate changes for longer.
No Early Repayment Charges
Trackers with no ERCs might have slightly higher margins but offer valuable flexibility worth 0.10-0.20% for many borrowers.
Avoid Collared Trackers
Some "cheap" trackers have a floor (e.g., never below 3%). These limit your benefit if rates fall significantly.

When is a Tracker Cheaper Than a Fixed Rate?
Trackers are currently more expensive than fixed rates, but this could change if the Bank of England cuts rates. Here's the break-even analysis:
Break-Even Scenarios for 75% LTV (£250k mortgage)
Verdict: At current rates, you need the BoE to cut by 0.75% or more for a tracker to beat a 2-year fixed. If you expect 3+ rate cuts in 2026, a tracker could save money over the full term.

How to Get the Cheapest Tracker Mortgage
1. Improve Your Loan-to-Value (LTV)
The single biggest factor in getting a cheap tracker is your deposit size:
- • Save for a bigger deposit if possible
- • Wait for house price growth to improve LTV naturally
- • Consider overpaying to reach the next LTV band before remortgaging
- • Each 5% LTV improvement typically saves 0.10-0.15% on your rate
2. Use a Whole-of-Market Broker
Brokers have access to exclusive tracker deals not available directly:
- • Access to broker-only deals with better margins
- • Can search 100+ lenders simultaneously
- • Know which lenders offer the best tracker margins for your profile
- • Free service (paid by lender commission)
3. Consider Lifetime vs Term Trackers
Lifetime trackers often have the lowest margins but consider the trade-offs:
- • Lifetime: Lower margin, longer rate exposure, maximum flexibility
- • 2-year: Higher margin, limited exposure, need to remortgage
- • 5-year: Middle ground but less common for trackers
4. Time Your Application
Tracker margins can change with market conditions:
- • Apply just after a base rate rise when margins might be lower
- • Avoid applying during market uncertainty when margins widen
- • Lock in your rate up to 6 months before you need it
- • Watch for lender promotions (often quarter-end)
