Introduction: When “Your Rate” Isn’t Guaranteed Yet
Few moments in the mortgage process feel as frustrating as hearing your rate has changed — sometimes days before completion. Clients often assume this means a lender has “moved the goalposts,” but in truth, reprices are a normal part of how mortgage markets work.
In a world where swap rates can fluctuate daily and lenders fund billions of pounds in fixed-term money, product pricing must constantly adjust to stay aligned with market cost and risk. The trick is understanding when reprices are likely, why they happen, and how to act quickly before they affect your case.
This guide explains the mechanics behind lender reprices, the difference between rate locks and offers, and the practical tactics Willow Private Finance uses to help clients avoid nasty surprises.
How Reprices Work, The Engine Room of Mortgage Pricing
When a lender “reprices,” they’re not trying to penalise borrowers. They’re recalibrating rates in line with their cost of funds and competitive position.
Most lenders benchmark pricing against swap rates — the cost of fixed-term funding for two, five or ten years. These swaps move continuously as markets react to inflation, bond yields, and central bank expectations.
If you’ve read our earlier guide,
Should You Wait for a Rate Cut or Lock Now? A Decision Framework, you’ll know that fixed mortgage pricing often changes before the Bank of England acts. The same applies to reprices — lenders anticipate where costs are going and adjust ahead of time.
In practice, a lender’s treasury desk monitors funding costs daily. Once the cost of wholesale funding rises or falls beyond a tolerance threshold (often around 0.10–0.20%), the mortgage team issues a “rate sheet reprice” — either pulling old products or launching new ones.
Why Your Rate Isn’t Locked Until You Have an Offer
Borrowers sometimes assume that once they’ve received an illustration or Decision in Principle, the rate is fixed. Unfortunately, that’s not the case.
A rate only becomes guaranteed once the lender has produced a formal mortgage offer — and even then, some lenders apply deadlines before completion.
Before offer, your rate remains a quote, not a commitment. If the lender reprices in that window, your broker must resubmit the application on the new rate or switch product where possible.
That’s why speed and communication matter. At Willow Private Finance, our advisors monitor daily repricing alerts and push applications through to offer stage quickly when the market looks volatile.

What Triggers a Mid-Application Reprice
There are four main drivers behind reprices — some external, some internal:
- Swap Rate Movements:
The single biggest factor. Even a small increase in 5-year swaps can force lenders to raise fixed-rate pricing to maintain margin. - Funding Line Availability:
Banks have quotas for how much money they deploy at certain rates. Once they reach internal funding caps, products are withdrawn until the next tranche of liquidity is priced. - Competitor Behaviour:
Mortgage pricing is highly competitive. If one lender undercuts the market, others may follow — but when that lender pulls back, the market often shifts within 24 hours. - Operational Load:
Lenders sometimes reprice simply to manage pipeline volumes. When application queues get too long, they nudge rates upward to slow demand temporarily.
Understanding these triggers helps borrowers plan. For instance, if markets are volatile or inflation data is due, we’ll typically advise locking early — before repricing cascades through the sector.
The Hidden Risk Window: Between Submission and Offer
Repricing risk is highest between application submission and formal offer.
This period — typically 3–10 working days — is when underwriting, valuation, and document checks occur. If the lender reprices during that time, your application may be caught in transition.
Some lenders honour “pipeline protection,” meaning they’ll honour the original rate if the case is already submitted before the reprice deadline. Others don’t — meaning your case automatically moves to the new, higher rate.
This is why Willow Private Finance uses real-time monitoring and dedicated underwriter contact lines to fast-track cases in volatile markets.
Our objective is simple:
get you to offer before the reprice hits.

How to Protect Yourself From Repricing Risk
You can’t stop reprices, but you can manage them intelligently. Here’s how:
- Move quickly once you’ve chosen a product. The market doesn’t wait for paperwork.
- Get documents ready in advance. Incomplete applications lose time that matters.
- Work with a broker who tracks reprices daily. We see lender changes hours before they go live.
- Consider lenders with pipeline protection policies. Some protect rates up to 10 days post-change.
- Ask about dual-application strategy. Submitting a backup with another lender can preserve leverage if one reprices.

Repricing in 2025: Why It’s Happening More Often
The post-2022 rate environment has made reprices more frequent than ever.
Lenders now adjust products weekly — sometimes daily — as they navigate narrow margins, market volatility, and regulatory capital buffers.
In the past, lenders might have repriced once a month. Today, a single inflation release can trigger a wave of updates across the sector by lunchtime. This is why monitoring and timing have become central to mortgage advice in 2025.
Borrowers should see reprices not as unfair, but as a reflection of how dynamic modern mortgage funding has become. The key is agility — being ready to lock the right deal at the right moment.

Frequently Asked Questions
Why do lenders reprice so often now?
Because swap rates, funding costs and capital requirements fluctuate daily. Lenders must adjust pricing to maintain profit margins and risk balance.
Can my rate change after I’ve applied?
Yes — unless you’ve received a formal offer and your lender has confirmed the rate is locked, repricing can still affect your application.
What does “pipeline protection” mean?
It’s a policy some lenders use to honour the original rate for applications submitted before a reprice, even if processing isn’t complete.
How can I protect myself from repricing?
Submit a complete application quickly, use a broker who tracks reprices, and prioritise lenders offering pipeline protection.
Is it worth waiting for a lower rate?
Not always. Market reprices can move both directions — a sudden rise can cost more than any potential fall might save.
