How Do Tracker Remortgages Work?
A tracker mortgage has an interest rate that directly follows, or tracks, the Bank of England base rate at a set margin above or below it. For example, if a tracker is set at base rate plus 0.75%, and the base rate is 4.5%, your mortgage rate would be 5.25%. If the base rate then drops to 4%, your rate would automatically fall to 4.75%.
This direct link to the base rate is what distinguishes tracker mortgages from other variable-rate products. Unlike a lender's standard variable rate (SVR), which the lender can change at their discretion, a tracker rate moves only when the base rate moves, and by exactly the same amount. This transparency is one of the key attractions of tracker deals.
There are several types of tracker mortgage available in the UK market:
- Fixed-period trackers — These track the base rate for a set period, typically 2 or 5 years, after which you move onto the lender's SVR unless you remortgage. During the tracker period, early repayment charges may apply.
- Lifetime trackers — These track the base rate for the entire term of your mortgage. They often come with no early repayment charges, giving you complete flexibility to leave at any time without penalty.
- Discount trackers — Some trackers are set below the base rate, though these are relatively rare. More commonly, the tracker margin is above the base rate, with the margin varying depending on your LTV, credit history, and the lender's pricing.
It is important to understand that with any tracker mortgage, your monthly payments are not fixed. They will change whenever the Bank of England adjusts the base rate, which typically happens at one of the eight Monetary Policy Committee meetings held throughout the year.
Advantages and Risks of Tracker Remortgages
Tracker remortgages offer a distinct set of advantages compared to fixed-rate deals, but they also carry specific risks that you should carefully consider before making your decision.
Key advantages
- Automatic rate reductions — When the Bank of England cuts the base rate, your mortgage rate falls immediately and by the same amount. You benefit from lower rates without needing to remortgage or take any action.
- Complete transparency — You always know exactly how your rate is calculated. There is no ambiguity, unlike with an SVR where the lender has discretion over rate changes.
- Potentially lower starting rates — Tracker rates can sometimes be lower than equivalent fixed rates, particularly when the market expects the base rate to remain stable or fall.
- Flexibility with lifetime trackers — Lifetime tracker deals often come with no early repayment charges, meaning you can switch to a different product or pay off your mortgage at any time without penalty. This level of flexibility is unusual in the mortgage market.
- No remortgage hassle — With a lifetime tracker, you do not need to go through the remortgage process every few years. Your rate adjusts automatically, saving you time and the costs associated with switching deals.
Key risks
- Rising rates — If the base rate increases, your payments will go up by the same amount. A series of rate rises could significantly increase your monthly outgoings, potentially stretching your budget.
- Budgeting uncertainty — Because your payments can change, it is harder to budget precisely compared to a fixed-rate mortgage. You need to ensure you have sufficient financial headroom to absorb potential increases.
- No rate cap on most deals — The majority of tracker mortgages have no upper limit on how high your rate can go. Some deals include a rate cap, but these are relatively uncommon and tend to come with a higher starting margin.
Understanding your own risk tolerance and financial resilience is crucial when considering a tracker. If you have comfortable financial buffers and can absorb moderate payment increases without difficulty, a tracker can be an excellent choice. If you are on a tight budget with little room for increased costs, a fixed rate may be more appropriate.
When Is the Right Time to Choose a Tracker Remortgage?
The timing of your decision to choose a tracker remortgage can significantly affect how well it works for you. While nobody can predict interest rate movements with certainty, there are market conditions and personal circumstances that make a tracker more or less attractive.
Favourable conditions for a tracker
Tracker mortgages tend to be most attractive when the consensus view is that interest rates are likely to remain stable or fall. If the economy is slowing and the Bank of England is signalling potential rate cuts, a tracker allows you to benefit from each reduction automatically. Following periods of rate increases, when the market anticipates the peak has been reached, trackers can offer excellent value.
When fixed rates carry a premium
Sometimes the gap between tracker and fixed rates widens significantly. This happens when lenders price expected future rate rises into their fixed-rate products. In these circumstances, a tracker can offer a substantially lower initial rate, and if the predicted rate rises do not fully materialise, the tracker borrower benefits.
When you value flexibility
If you think you might want to move home, make large overpayments, or pay off your mortgage entirely within the next few years, a lifetime tracker with no ERCs gives you complete freedom to do so. This flexibility has a genuine financial value that should be weighed against the payment certainty of a fix.
Less favourable conditions
If the base rate is at historically low levels and is widely expected to rise, fixing your rate might be the safer choice. Similarly, if you are on a tight budget and cannot comfortably absorb payment increases of several hundred pounds per month, the security of a fixed rate is likely more appropriate.
It is also worth considering that the best time to choose a tracker often coincides with periods of uncertainty, when fixed rates have been pushed up by market expectations. Consulting an FCA-regulated mortgage adviser can help you assess the current market dynamics and make an informed decision.
