Most mortgage borrowers hear the term Standard Variable Rate (SVR) at some point, usually when their fixed deal is about to end. It sounds harmless, a default setting. In reality, it’s one of the most expensive and least predictable rate types for a mortgage to sit.
This guide explains what an SVR really is, why lenders have them, how people end up on one, and the few circumstances where staying on an SVR briefly might make sense.
What SVR actually is
Every lender has a Standard Variable Rate, the rate your mortgage automatically moves onto when your fixed or tracker deal ends.
An SVR is:
- Set entirely by the lender
- Not directly linked to the Bank of England base rate
- Changeable at any time
- Usually, the lender’s highest rate
- Flexible, with no early-repayment charges
It’s a holding pattern, not a product you actively choose.
Why lenders have SVRs
SVRs exist for simple reasons:
- A default rate is needed when deals expire
- The lender can price in risk and admin costs
- They offer full flexibility, important between deals
- They generate profit, because many borrowers don’t remortgage in time
The SVR itself isn’t unfair or hidden. It’s just rarely good value for consumers compared to other mortgages.
Why being on an SVR is usually a bad idea
1. SVRs are almost always more expensive
In the current market (November 2025), many sit around 7–9%, compared to 4–5% for a typical fixed deal.
On a £250,000 mortgage:
- 6% SVR → £1,610/month
- 4.5% fixed → £1,266/month
That’s £344 more every month, or over £4,000 a year.
2. The lender can change the rate whenever they like
There’s no formula. No direct link to the base rate. Lenders can adjust the SVR quickly depending on their funding costs or business strategy.
3. It affects your long-term affordability
Higher payments reduce your spare income, which lenders consider when assessing affordability. Ironically, being on an SVR can make it harder to qualify for a cheaper deal later.
4. You get no extra benefits for the higher cost
You don’t get better service, faster processing, or special terms.
You’re simply paying more for the same mortgage.
How people end up on an SVR
Most borrowers don’t choose an SVR.
1. The fixed deal ended and nothing was arranged
Remortgaging slips down the priority list. You get a letter from the lender… then suddenly you’re on a higher rate.
2. Delays in the remortgage process
Common blockers include:
- slow solicitors
- down-valuations
- document issues
- job changes mid-application
- missing bank statements
- expired ID
Even a two-week delay can cost hundreds.
3. A planned short-term stopgap
A small minority stay on the SVR intentionally because:
- they’re about to sell
- they expect to clear the mortgage soon
- they need total flexibility with no ERCs
These situations are the exception, not the rule.
When an SVR can make sense (briefly)
A brief period on an SVR can be reasonable if:
- You’re completing a sale shortly
- You’re awaiting a remortgage offer, and the timeline is tight
- You plan a large overpayment
- Early-repayment charges on your current deal make switching now too costly
But this should be measured in weeks, not months.
Why SVRs matter more than people think
The SVR isn’t just another rate. It’s the rate that quietly erodes:
- your monthly budget
- your ability to save
- your ability to overpay
- your long-term affordability
- your overall equity build-up
An extra £300–£500 a month doesn’t feel huge in isolation, but over a year or two it becomes real money.
In a rising-rate environment, the gap between SVRs and fixed deals widens even further.
How to avoid ending up on an SVR
1. Start remortgaging 6 months before your deal ends
Most lenders allow product transfers or full remortgage applications this early.
The earlier you start, the fewer surprises. A good mortgage adviser would've been in touch with you about remortgaging at this point.
2. Track the expiry date
Your lender will notify you, but it’s better to know before they tell you.
3. Ask your current lender for retention products
These are new deals available to existing customers.
Sometimes competitive, sometimes not, but useful as a benchmark.
4. Keep your documents ready
Most delays come from missing items:
- three months of bank statements
- payslips or SA302s
- ID that hasn’t expired
- evidence of deposit sources if extra funds are added
The more organised you are, the faster the remortgage moves.
5. Keep an eye on your credit file
Address mismatches, open disputes, old linked addresses, and dormant accounts all slow things down.
6. Speak to a mortgage adviser early
Especially relevant if you have:
- variable income
- self-employment
- credit blips
- changing jobs
- high loan-to-value
- quirks in the property (flats above shops, timber frames, etc.)
A good adviser narrows down the right lender and catches issues before they block the remortgage.
If you’re already on an SVR
You’re not alone. And you don’t need to panic.
A simple sequence helps:
- Check when your old deal ended; knowing how long you’ve been on the SVR helps prioritise.
- Ask your lender what deals you can move to immediately; a product transfer can often be arrangedin days.
- Speak to a mortgage adviser; they may find cheaper options elsewhere.
- Gather your documents, speed matters. The longer you stay on SVR, the higher the cost.
Final Thoughts
The SVR is the most expensive route most people take without choosing it. It exists to fill the gap between deals, not as a place to stay.
If you’re unsure what your lender’s SVR is, when your deal ends, or whether you can move to something cheaper, a mortgage adviser can help you work through it calmly.
