Locking in a deal now is extremely advisable. You're effectively making sure the rate doesn't go any higher, and if rates come down with that lender and you're using a broker, you can follow rates down between now and when you complete.

The Bank held rates again this month, but that's not the full story. Inflation crept up to 3.1% in August and three of the nine committee members already voted to raise rates, not hold them, so a rise later this year can't be ruled out. Mortgage pricing has been climbing regardless, average two and five year fixes are already above 5%, because lenders price off where rates are heading, not just where they sit today. My advice to anyone with a deal ending in the next year: don't wait for the renewal letter. Most lenders let you secure a new rate up to six months before your current deal ends, so lock in early. You can usually swap to something cheaper later if rates fall, but you're protected if they don't. Waiting for certainty in this market means waiting for a rate that's already gone up. Six months out isn't early, it's just sensible.

I'm not going to give the blanket 'lock in now' that these stories usually attract, because whether it's right depends entirely on your own situation and when your current deal ends. What I can do is explain how it works. You can usually secure a new rate up to six months before your deal expires, and if pricing improves before you complete, most lenders let you switch to the cheaper one. So securing early tends to be low-risk, because it gives you a rate you can still improve on if the market drops. On the backdrop, fixed rates are priced off where lenders think the Bank is heading, so they move before the base rate does, and with inflation near 4% and the Bank warning about rises, little right now points to imminent falls. That's background, not advice. The genuinely useful step is to get advice specific to you and your deal end date, then decide from a position of understanding.

Borrowers approaching the end of a fixed deal shouldn’t wait for the Bank of England to pull the trigger. Mortgage rates are driven by market expectations, so lenders can hike their rate or pull their cheapest deal before the base rate rises.

If your deal ends within six months, start shopping around now. Securing a new rate early gives you protection if rates climb, while you may still be able to switch to a cheaper deal if rates fall before completion.

Don’t be blinded by the headline rate, though. Arrangement fees, incentives and early repayment charges can turn an apparent bargain into a costly mistake.

No one has a crystal ball, but with inflation forecast to hit 4%, locking in a payment you can comfortably afford could provide valuable peace of mind.

With mortgage rates rising, the sensible approach is to secure a new deal as soon as you reach the six-month mark before your current mortgage ends. Do not try to time the market.

Ideally, secure a deal with no upfront valuation cost and add any lender fee to the mortgage. That locks in the rate without committing any money and, importantly, even once you have a mortgage offer you are not committed to actually taking that mortgage. If a better deal comes along later, you can simply take that instead.

You then have six months to monitor the market. If rates rise, you are protected. If they fall, a good mortgage broker should be looking to switch you onto the cheaper rate.

Even a 0.25% rise matters. On a £300,000 mortgage, that is roughly £1,500 of additional interest over two years. You can protect yourself if rates rise and still benefit if they fall. Why gamble when you do not need to?

Locking in a deal now is an absolute must, if you do this six months in advance, you are essentially reserving a rate, if something better comes along before your switch takes place you can always jump onto the new rate. Its a win/win situation for anybody looking for a new mortgage. Mortgage hunters shouldnt be asking "is now the time" they should be asking "how do i do it"

With Trump currently controlling the Global market, everything is too volatile to just be sitting back and waiting. The biggest losers will be those that dont act at the earliest opportunity.

If you're taking a new mortgage deal with the same lender, it's a good idea to start reviewing your options early. Some lenders will give borrowers six months to select a new deal before their current rate ends. Once you've locked in, you know that's the most you'll pay – and if rates come down, you can ask your lender to trade for the lower one before your new rate starts.

No one can predict the future and there is no one "right" or "best" time to lock in a deal – being proactive, reviewing your options early, and getting good advice is the best strategy for securing a deal that is affordable for you.

It's important to bear in mind that base rate movement only really impacts variable or tracker mortgage rates – if you're choosing a fixed rate, those prices are set by money markets which are driven by all sorts of things including geopolitical uncertainty. Don't let talk of the base rate send you into a panic. A broker will help you find the best option for you.

Yesterday. Analysts reckon the Bank of England could push rates from 3.75% to 4.75% by July 2027, so there's no time to lose. Trying to "time the market" on a mortgage isn't strategy, it's a gamble. Lenders price fixed rates on forward swap rates, so rising inflation expectations get baked into deals long before the Bank actually moves. The moment you enter your lender's early booking window, typically three to six months before your current fix ends, lock in. Securing a rate early is your insurance policy: if borrowing costs rise, you're protected; if rates fall before completion, most lenders let you ditch the original offer for a cheaper one. Avoid a lender's Standard Variable Rate at all costs, it sits well above mainstream fixed products. Two-year fix for flexibility or five-year for stability comes down to your appetite for risk. But locking in early always gives you maximum downside protection.

You have a window of opportunity 6 months before your deal expires - and whether the rates are moving in different directions, having a mortgage deal reserved or offered will give you a baseline to work on. Brokers can be proactive and adjust your deal if rates move in your favour and are cut, while also protecting you against rate increases. Paying to exit a deal early is typically too expensive for most to swallow versus the saving, but just be ready to remortgage or switch rates with your broker, they will be worth more than their weight in gold.

Yes, get it locked in 6 months before your current deal ends. This protects you against future rises, but also keeps the door open to locking in better rates should they come up.

Six months before a fixed deal ends is a sensible time to start reviewing your options. The mistake is waiting for a particular Bank of England decision because fixed mortgage rates can move before the Bank acts, and sometimes in a different direction.

If you find a suitable deal, securing it early can provide a safety net while you continue watching the market. The aim isn’t to guess the absolute bottom of mortgage rates, but to avoid being forced into a last-minute decision.

If you are either within 6 months of requiring a remortgage or you have had a purchase price agreed on a new property, you should look to lock a rate as quickly as possible. Rates are only trending in one direction at the moment, so borrowers should be quick and decisive on securing a mortgage product.

Borrowers shouldn’t gamble on mortgage rates getting cheaper.

With inflation heading higher and the threat of interest rate rises back on the table, anyone whose mortgage deal ends in the next six months should consider locking in a new rate now.

You don’t have to wait for the Bank of England to raise rates for mortgage prices to jump, lenders can react to changing expectations almost overnight in line with the future financial market predictions.

The good news is that securing a deal now can give borrowers a safety net. If rates rise, you’re protected, while if they fall before completion, you may still be able to switch to a cheaper deal.

Waiting for the perfect rate could prove an expensive gamble.
