Should I Wait to Remortgage or Do It Now?

The Case for Remortgaging Now

If your current deal has ended or is about to end, there is a strong argument for remortgaging sooner rather than later. Every month you spend on the SVR is a month of higher-than-necessary interest payments. Even if you believe rates might fall further in the future, the savings from moving off the SVR now can be substantial.

Acting now also provides certainty. You know exactly what today's rates are. You do not know what they will be in three months or six months. Mortgage rates can be volatile, reacting to economic data, geopolitical events, and changes in market sentiment. A deal that looks good today might not be available tomorrow.

Furthermore, most lenders offer rate locks of up to six months. If you secure a deal now and rates fall before completion, many lenders will let you switch to the lower rate at no extra cost. This means acting now does not preclude you from benefiting from future rate reductions. You get the security of a locked-in rate with the option to improve it.

The Case for Waiting

There are legitimate reasons to wait in some circumstances. If you are still within a fixed rate deal with significant early repayment charges, waiting until those charges reduce or expire could save you money. Most ERCs decrease each year, so if you have a year or less until your deal ends, the penalty will soon be much smaller or eliminated entirely.

If the economic outlook strongly suggests that rates will fall significantly — for example, if the Bank of England has signalled a series of rate cuts — waiting could result in a better deal. However, this is speculative, and predicting rate movements accurately is notoriously difficult, even for financial professionals.

Your personal circumstances might also warrant a delay. If you are about to receive a bonus, pay off a significant debt, or make a home improvement that would increase your property's value, waiting a few months could improve your financial profile and qualify you for a better rate. Just be sure to weigh the potential improvement against the cost of remaining on your current rate in the meantime.

Calculating the Cost of Waiting

To decide whether waiting makes sense, you need to understand the cost. If you are on the SVR at 7% with a 200,000-pound balance, you are paying roughly 1,167 pounds per month in interest. If you could remortgage today to a rate of 4.5%, your monthly interest would be about 750 pounds — a saving of 417 pounds per month. Waiting three months costs you approximately 1,250 pounds in additional interest.

For waiting to make financial sense, the rate you eventually secure would need to be low enough to recoup those lost savings over the life of the new deal. If waiting three months gets you a rate that is 0.1% lower, you would save about 17 pounds per month on a 200,000-pound mortgage — meaning it would take over six years to recoup the 1,250 pounds you lost by waiting. That is unlikely to be worthwhile.

Conversely, if you are still within a fixed rate deal and the ERC is about to drop from 3% to 1%, waiting could save you 4,000 pounds on a 200,000-pound balance. In that case, the maths clearly favours waiting. The key is to run the specific numbers for your situation rather than relying on general assumptions.

A Practical Decision Framework

To make this decision, ask yourself three questions. First, what am I currently paying? If you are on the SVR, the urgency to act is high. If you are in a fixed rate deal with no imminent end date, you have more time. Second, what would I pay on a new deal today? Get a quote from a broker or compare deals online. Third, what is the realistic upside of waiting, and what is the downside risk?

If the difference between your current rate and the best available rate is significant — say, more than one percentage point — and you are not locked into a deal with ERCs, the case for acting now is strong. The potential benefit of waiting for a slightly better rate rarely outweighs the certain cost of paying more in the meantime.

If you are genuinely torn, consider a compromise: secure a rate now with a lender that offers a rate match or rate switch policy, giving you protection against rises while keeping the option to benefit from falls. This strategy gives you the best of both worlds and removes the pressure of trying to time the market perfectly.
