When should you remortgage?

A remortgage just means moving your mortgage to a new deal — either with your current lender or a different one. Here's what that involves, and the moments people often start thinking about it.

What a remortgage actually is

A remortgage is when you replace the mortgage on your current home with a new one. You're not moving house — you're just swapping the deal that sits on top of it.

You can remortgage with a new lender, or stay with your current one and move onto a fresh deal (that second option is often called a product transfer). Both are worth knowing about, because they can work quite differently.

People do this for all sorts of reasons — a deal ending, a change in circumstances, or wanting to set the mortgage up differently. There's no single 'right' time; it depends entirely on you.

The moments people tend to think about it

There's no date in the calendar that says 'remortgage now'. But there are a handful of moments that tend to get people looking:

• Your current deal is coming to an end. Fixed and tracker deals usually run for a set period. When they finish, many lenders move you onto their standard variable rate — so a lot of people review their options before that point.
• You want to borrow more. Some people look at borrowing more against their home for a specific reason, such as home improvements. Whether that's possible or sensible depends on your situation.
• Your circumstances have changed. A shift in income, a new job, or wanting to add or remove someone from the mortgage can all prompt a review.
• You want to change the mortgage itself — for example, adjusting the length of the term, or moving between repayment and interest-only.
• The wider rate picture has moved. When interest rates change, people naturally wonder how their own deal now compares.

None of these mean you have to remortgage. They're simply the questions that tend to send people looking.

Things people check before switching

Before making a move, there are a few practical things people usually look into:

• Early repayment charges. If you leave your current deal before it ends, your lender may charge a fee. It's worth knowing whether one applies, and roughly when it falls away.
• Fees on the new deal. A new mortgage can come with arrangement or product fees, and sometimes valuation or legal costs. The headline interest rate isn't the whole picture — the overall cost is.
• Timing. Arranging a remortgage takes time, so people often start looking a few months before their current deal ends, rather than at the last minute.
• Your balance versus your home's value. The relationship between what you owe and what your home is worth (your loan-to-value) can affect which deals are open to you.

I can't tell you how these stack up in your case — but they're the sort of thing a good adviser will lay out clearly.

Through an adviser, or straight to a lender?

You can arrange a remortgage yourself by going directly to a lender, or you can use a mortgage adviser (a broker). Both are valid, and it's genuinely a trade-off.

Going direct can be simple if you already know what you want — and some lenders keep certain deals for people who come to them directly, which a broker can't always access.

Using a whole-of-market adviser means someone searches across a wide range of lenders on your behalf, handles the paperwork, and talks through the trade-offs for your circumstances. Some brokers charge you a fee and some don't — a good one will tell you clearly up front, before you commit to anything.

Neither route is automatically better. It comes down to how much you want to do yourself and how involved your situation is.

How a remortgage usually works

Every case is different, but the shape of a remortgage is fairly consistent:

• You — or your adviser — review the options and compare deals across lenders.
• You apply, and the lender checks affordability and usually values the property.
• Legal work transfers the mortgage from the old lender to the new one.
• The new deal completes, and your old mortgage is paid off.

It tends to take weeks rather than days, which is why people usually give themselves some runway. If you stay with your current lender on a product transfer, it's often simpler, because there's no new lender or legal work involved.

So, when's the right time for you?

The honest answer: there isn't a universal 'best time' to remortgage. The right moment depends on your deal, your plans, the fees involved, your circumstances, and what the wider market is doing — and all of that is personal to you.

What usually helps is understanding your own numbers first: when your current deal ends, whether an early repayment charge applies, and what you'd want a new mortgage to do for you. From there, a proper conversation with a qualified adviser can weigh it all up against the whole market — with no obligation to change a thing.
