In this article, we’ll examine the various lengths of fixed-term deals offered across the mortgage market, the benefits of short-term vs. long-term fixes, and how to decide which is the best option for you.

What’s the longest fixed-rate mortgage term you can get?

Traditionally, 10-year fixed-rate mortgages have been the longest widely available. Over the past couple of years, 15-year, 30-year, and even 40-year fixed-rate deals have become available, with one lender even securing a licence to offer a 50-year fixed-rate mortgage term in the future. However, with the current uncertainty in the market, leaving lenders needing to constantly change their product offering, fixed-rate terms longer than ten years can be difficult to secure.

While a fixed-rate period of up to 50 years may offer longer-term certainty for your monthly payments, the overall interest paid will likely be higher. It’s important to weigh these factors before deciding which option best suits your situation.

The vast majority of fixed-rate borrowers tend to opt for 2-, 3-, or 5-year deals, with most high-street lenders offering a maximum of 5-year fixed rates and a few offering 10-year deals.

Are long-term fixed-rate mortgages a good idea right now?

Whilst the cost difference between fixing for 2 years and 5 years was once a deterrent in opting for the latter, the gap between interest rates available on 2 and 5-year deals has narrowed considerably. Even some 10-year fixed-rate deals are now negligibly more expensive than 2-year fixes.

Whether it’s a good idea to fix for a short or longer period will always depend on your personal circumstances and preferences. However, it’s prudent to consider the current financial climate and recent interest rate fluctuations when making a decision, too.

Any future rises in the Bank of England base rate will affect your mortgage interest rates unless you have already secured a fixed-rate deal.

Benefits vs. risks

The following table explores why a longer-term fix may or may not be the right option for you. It’s strongly advisable, however, to discuss this decision with an experienced broker before committing to a deal.

Benefits:

  • If interest rates rise again, you will be unaffected for the full duration of the fixed-rate period, and you’ll have the peace of mind that your monthly payments will remain affordable for longer.
  • You won’t need to remortgage for a better deal every couple of years, saving yourself the hassle and cost of the fees involved in this process. A 10-year deal may have a higher interest rate than a 2-year deal but will save the fees involved in the five remortgages necessary over the same duration on 2-year fixes.
  • Suppose changes in the market lead lenders to implement a general tightening of their criteria for new mortgage applications. You won’t need to worry about meeting these to remortgage for a new deal. For example, suppose the cost of living crisis impacts your credit score. In that case, this won’t be so problematic with a longer fixed-rate deal, as you will either have longer to repair your credit score or, in the case of a lifetime fix, never need to be credit scored by your lender again.
  • There is less difference between the interest rates on short and long-term fixes than there used to be, so now may be a good time to take advantage of lower-priced long-term fixed rates, which may not be available.

Risks:

  • In a longer period of time, there are more opportunities for interest rate fluctuations. If they fall, you won’t benefit from the lower rates available. In contrast, with a discount or tracker-rate deal, for example, you would likely automatically benefit from any falls in interest.
  • If you do want to take advantage of a better deal or move home before the fixed-term ends, you’ll likely have to pay early repayment charges (ERC) and exit fees, which are typically higher the longer the duration of your fixed-rate period. Typical ERCs range between 1-5% of the outstanding loan and, in some cases, can negate any financial benefits of taking a more competitive deal.
  • It’s impossible to estimate whether you would save more money taking multiple shorter deals or a longer-term fixed deal, so there’s always the chance that you could end up paying more interest overall if you fix for longer.
  • Interest rates are typically higher the longer the fixed-rate deal, so whilst your monthly payments will be set in stone, they may be slightly higher than on a shorter deal.

How can you compare the best long-term fixed-rate mortgages?

It isn’t easy to gauge the best move regarding which fixed-rate period will save you the most money in the long run. A broker with plenty of experience with the volatility in the mortgage market is likely to be well-placed to answer this type of question.

As well as helping you to decide how long to fix for or whether fixing your rates at all is the right option for your circumstances, brokers stay informed of the constantly changing rates and deals available from all lenders across the market, and they often have access to deals not advertised to the general public. This means that they will be able to find the best rates available for your circumstances at any given time.

Fixed-rate deals won’t suit everyone, and if a variable rate, such as a tracker, would be more suitable to your current circumstances, they will be able to advise you about the most competitive rates in this area, too.

The brokers we work with are experienced in securing the most appropriate and competitive deals. Whether you’re self-employed, have bad credit, or have any other circumstances that may mean you have more specialist mortgage needs, they’ll help you make the most of the options available.

Lenders available

In recent years, the number of lenders offering 10-year, 15-year, and even lifetime fixes has increased, so there are options available to suit most preferences. The fairly new addition of 40-year fixes means that they are currently only offered by a very small number of lenders, and 50-year fixes, whilst planned, are not yet available.

Lenders who traditionally offer mortgages with fixed rates periods of 10 years or longer include…

  • Yorkshire Building Society
  • Barclays
  • Nationwide
  • Virgin Money
  • HSBC

Interest rates and mortgage terms are always subject to change, and the above information should be used simply as a guide. To indicate why it’s important to check current deal availability with a broker, the average UK mortgage deal has a shelf-life of just 17 days before the rates and/or terms are changed. It’s, therefore, perfectly possible that a deal you saw online last week or even yesterday is no longer available today.

Do you get a better rate if you’re an existing customer?

If you already have a mortgage and are looking to move on to a more competitive deal, your existing lender may be able to offer you a preferential rate over a new customer; however, this does not necessarily mean it will be lower than the rates available from other lenders.

To ensure you achieve the most competitive rates on the fixed-term period you’re looking for, and based on your circumstances, you would need to compare every deal available across the entire market. With over 4,000 deals available at any given time, this can be a mammoth task without a whole-of-market broker’s help.
