Building Society Standard Variable Rate Mortgages: What Happens When Your Deal Ends?

When your fixed, tracker or discounted mortgage deal ends, your building society will normally move you onto the follow-on interest rate named in your mortgage agreement unless you arrange another deal. This is often called the Standard Variable Rate (SVR), although some building societies use different names.

An SVR can give you flexibility to switch or overpay, but it is often higher than the rates available on new mortgage deals. Because the lender can change it, your monthly repayments may rise or fall.

This guide explains how UK building society SVRs work, current examples from major lenders, what a rate change could mean for your repayments and how to avoid paying a higher rate unnecessarily.

Standard Variable Rate Mortgage: Quick Answers

What is an SVR? A variable mortgage interest rate set by the lender, usually applying after an introductory mortgage deal finishes.
Who sets the rate? The individual building society, subject to its mortgage terms and applicable rules.
Is it linked to Bank Rate? Not necessarily. Unlike a straightforward tracker, a typical SVR does not automatically move point-for-point with the Bank of England base rate.
When does it start? Usually when your fixed, discounted or other introductory deal ends, unless a replacement deal begins.
Can repayments rise? Yes. A lender’s SVR can increase or decrease, affecting the interest charged and your mortgage payment.
Can you leave an SVR? Generally yes. Many SVRs have no Early Repayment Charge, but your own mortgage conditions must be checked.
Is an SVR expensive? Often. Standard variable rates are commonly higher than the lender’s available fixed or tracker deals.
Best first action Find your exact follow-on rate, deal expiry date and current product-transfer options.
Fast answer: If your building society mortgage is moving onto an SVR, compare the new monthly payment against a product transfer with the same lender and a remortgage elsewhere. Check fees and charges before switching. Do not assume you are required to remain on the SVR.

What Is a Building Society Standard Variable Rate?

A Standard Variable Rate is a mortgage rate controlled by the lender in accordance with the contract. It can change during the mortgage term, so your monthly repayment is not guaranteed to stay the same.

Most borrowers encounter an SVR when an introductory mortgage product expires. For example, someone with a two-year fixed-rate mortgage may automatically move to the lender’s SVR if they do not arrange a new rate before the fixed period ends.

During a fixed-rate deal

  • The agreed mortgage rate stays fixed for the deal period.
  • Payments are generally predictable if the loan arrangement does not otherwise change.
  • Early Repayment Charges may apply.
  • The mortgage offer specifies what happens after the fixed period.

After moving onto an SVR

  • The interest rate can change.
  • The monthly payment may increase or decrease.
  • Overpayment restrictions are often more flexible.
  • You can usually arrange a new mortgage deal without an SVR Early Repayment Charge.
Important distinction: an SVR is usually the interest rate for your existing mortgage after a deal ends. It is not a new mortgage application, and the lender does not necessarily reassess your affordability simply because the agreed follow-on rate begins.

How Much More Could a Standard Variable Rate Mortgage Cost?

The effect depends on your outstanding balance, repayment method, remaining mortgage term and the difference between your old and new rates.

Consider a hypothetical £200,000 capital repayment mortgage with 20 years remaining.

£200,000Outstanding mortgage
20 yearsRemaining term
4.00%Illustrative fixed rate
6.50%Illustrative SVR

At 4.00% interest

Approximately £1,212 per month

Capital and interest repayment mortgage, assuming 20 years remaining and a constant rate.

At 6.50% interest

Approximately £1,491 per month

Same balance and term, but a higher illustrative interest rate.

Estimated increase: about £279 per month. That is roughly £3,350 more over 12 monthly payments, before allowing for any changes in the balance, rate, term or fees.

Why your actual increase may be different

Mortgage balance A larger balance generally produces a larger change in monthly payments when the rate changes.
Remaining term A shorter remaining term usually means higher monthly capital repayments.
Interest-only borrowing An interest-only mortgage has a different payment calculation because capital is not normally repaid monthly.
Payment recalculation date The first payment at the new rate may differ from a normal full month’s payment.
Calculation note: The figures above are illustrations, not current mortgage quotations. They use standard repayment calculations, assume a constant interest rate and exclude product fees, arrears, insurance and other charges.

Does a Building Society SVR Follow the Bank of England Base Rate?

Not automatically. The Bank of England’s Bank Rate influences mortgage funding costs and market interest rates, but most standard variable rates are managed by the lender rather than tied to an exact Bank Rate formula.

A building society may increase, reduce or leave its SVR unchanged after a Bank Rate announcement, subject to its mortgage conditions and regulatory obligations.

Standard Variable Rate

  • Set and managed by the building society.
  • Can change without an identical Bank Rate movement.
  • No universal maximum margin over Bank Rate.
  • Some older products have contractual rate ceilings.
  • The lender must follow the applicable mortgage terms.

Bank Rate tracker

  • Usually follows an agreed external rate.
  • Commonly tracks Bank Rate plus a stated margin.
  • Changes follow the contract’s timing rules.
  • May contain floors, collars or other restrictions.
  • Can be more predictable in how the interest rate changes.
Example: If Bank Rate falls by 0.25 percentage points, your building society does not necessarily have to reduce a normal discretionary SVR by 0.25 percentage points. Check whether your own mortgage rate is discretionary, capped or directly linked to Bank Rate.

Standard Variable Rate vs Fixed Rate vs Tracker Mortgage

These mortgage arrangements behave differently. The appropriate choice depends on how much payment certainty you need, how long you expect to keep the mortgage and whether flexibility is valuable.

Feature
Standard Variable Rate
Fixed or tracker alternative
Rate changes
Lender can change its managed rate.
Fixed: unchanged during the deal. Tracker: follows its agreed index and terms.
Budget certainty
Lower because repayments can change.
Fixed rates offer more certainty; trackers remain variable.
Early Repayment Charge
Usually absent, subject to mortgage terms.
Can apply to fixed and some tracker products.
Overpayments
Often flexible or unlimited.
May be restricted during the product period.
Interest rate
Often higher than a competitive introductory deal.
Depends on the available product, LTV, fees and market pricing.
Typical appeal
Short-term flexibility and freedom to repay or switch.
Fixed: predictable repayments. Tracker: defined exposure to benchmark movements.
Practical comparison: A borrower who needs predictable monthly payments may prefer a fixed rate. Someone planning to repay the mortgage shortly might value an SVR without an ERC. Compare the actual mortgage terms instead of assuming one rate type is always better.

How to Leave Your Building Society’s Standard Variable Rate

There are usually two main routes: switch to a new mortgage product with your existing building society or remortgage to another lender.

If your deal is ending soon, review options before the higher follow-on rate starts. MoneyHelper recommends discussing your options with your existing lender around six months before the deal ends.

  1. Find your current mortgage rate. Check the latest statement, online mortgage account or mortgage offer.
  2. Confirm your deal expiry date. Identify when the introductory rate ends and when the follow-on rate begins.
  3. Check the applicable reversion rate. Confirm whether your mortgage moves to SVR, SMR, BMR, MVR or another contractual rate.
  4. Check Early Repayment Charges. Read the terms before arranging a switch that could start early.
  5. Request existing-customer deals. Ask your building society for the rates and fees available through a product transfer.
  6. Compare outside lenders. Check whether a remortgage elsewhere could reduce the overall cost after fees.
  7. Compare the correct mortgage term. Use the same remaining mortgage balance and repayment period when comparing options.
  8. Review your circumstances. Consider affordability, loan-to-value, moving plans and whether the mortgage has valuable legacy features.
  9. Check the new deal’s conditions. Review its rate, fee, ERC schedule, overpayment allowance and start date.
  10. Arrange the change and retain confirmation. Keep your existing mortgage payments running until the lender confirms the new arrangement.

Option 1: Product transfer

  • Stay with the same building society.
  • Often a simpler process for a like-for-like rate switch.
  • May not require a new affordability assessment.
  • Usually avoids changing the mortgage’s legal lender.
  • Limited to the provider’s available product range.

Option 2: Remortgage

  • Move the mortgage to another lender.
  • Compare a wider range of products.
  • Usually involves affordability and property checks.
  • May require conveyancing and other costs.
  • Could provide better overall value after fees.

Independent comparisonMoneyHelper: Remortgaging to Reduce Costs

After opening this link:

  1. Read when remortgaging may reduce monthly payments or overall interest.
  2. Review product fees, legal costs and Early Repayment Charges.
  3. Compare staying with your existing lender against switching providers.
  4. Consider mortgage advice if the comparison is complicated.
  5. Check whether the total savings justify any switching costs.
Legacy-rate exception: Before leaving a protected older mortgage rate, check whether you can ever return to it. Some Nationwide BMR and Skipton legacy-rate arrangements cannot be reinstated after switching to a newer product.

Is Staying on a Standard Variable Rate Ever Worth It?

Although SVRs are often more expensive, staying on one can make sense in particular circumstances. The main potential benefit is flexibility.

Repaying the mortgage soon A borrower expecting to clear the mortgage in the near future may wish to avoid a new fixed deal with an ERC.
Planning to move home If a sale is imminent, remaining flexible may be preferable to locking into a product that creates moving or repayment restrictions.
Making substantial overpayments Many SVRs allow unrestricted overpayments, although this must be confirmed from the mortgage agreement.
Waiting for a specific transaction A short period on SVR may be practical while an agreed property sale or remortgage is completing.
Do the calculation first: A period of several months on a higher SVR can cost more than the fee or charge you hoped to avoid. Compare the expected additional interest with any actual switching costs.

Why Older Building Society Mortgages May Have Different Variable Rates

One of the biggest mistakes is assuming every customer of a building society moves onto the same headline SVR.

Some older mortgage contracts carry a specific rate margin, cap or other feature that is no longer offered to new borrowers. Switching to a new product can permanently change the contractual follow-on rate.

Nationwide Base Mortgage Rate versus Standard Mortgage Rate

Nationwide’s Base Mortgage Rate is a legacy variable rate guaranteed to be no more than two percentage points above Bank Rate. Its Standard Mortgage Rate has no equivalent upper cap.

Nationwide states that customers who switch away from BMR to a new deal cannot later return to BMR. The relevant mortgage dates and former building society arrangements determine which rate applies.

Skipton SVR versus Mortgage Variable Rate

Skipton’s published rules distinguish products applied for before 30 December 2009, products applied for between that date and 14 November 2012, and newer mortgages.

These groups may follow SVR, a Base Rate Tracker or MVR. The rates can differ in their contractual ceilings and their relationship with Bank Rate.

Important: A legacy variable rate with a favourable contractual cap may be valuable even if a new fixed product initially looks attractive. Consider the implications of losing that protection permanently.

How an SVR Affects an Interest-Only Mortgage

For an interest-only mortgage, changes in the lender’s SVR normally affect the interest payment, while the capital balance remains outstanding unless you repay some of it separately.

For example, take an interest-only mortgage balance of £150,000.

£500 Approximate monthly interest at 4.00%.
£812.50 Approximate monthly interest at 6.50%.
£312.50 Monthly interest difference.
£150,000 Capital still owed if no capital repayments are made.

The illustration uses a constant balance and simple annual interest divided by 12. Actual payments depend on the lender’s interest calculation method and collection dates.

Interest-only reminder: Moving to an SVR does not remove your obligation to repay the capital at the end of the mortgage. Review your repayment strategy separately from the monthly interest payment.

What If the SVR Makes Your Mortgage Repayments Unaffordable?

Contact your lender as early as possible. You do not have to wait until you miss a payment before discussing support.

The FCA expects firms to support borrowers facing payment difficulties. Depending on your circumstances and the lender’s arrangements, possible options may include switching rates, reviewing the mortgage term, temporary payment changes or other tailored support.

Ask about a rate switch A replacement mortgage deal may reduce payments compared with the lender’s SVR.
Discuss mortgage term options A longer repayment term may reduce monthly payments but can increase the total interest paid.
Review temporary flexibility Participating Mortgage Charter lenders may offer certain eligible borrowers temporary interest-only payments or term changes.

Common Standard Variable Rate Mortgage Mistakes

Doing nothing when a fixed deal ends The mortgage may automatically move to a higher follow-on rate.
Assuming Bank Rate controls the SVR exactly A discretionary SVR does not necessarily rise or fall by the same amount as Bank Rate.
Ignoring the mortgage offer The contractual follow-on rate may differ from the building society’s main advertised SVR.
Not checking a legacy rate Switching can permanently remove favourable caps or older contractual features.
Comparing only headline rates A lower fixed rate with a substantial product fee may not be the best overall option.
Assuming unlimited overpayments Many SVRs are flexible, but you must verify your individual mortgage conditions.
Ignoring loan-to-value A change in mortgage balance or property value may affect which replacement deals are available.
Leaving a switch until the last minute Application processing and start-date rules can cause an avoidable period on the higher follow-on rate.

Checklist Before Your Building Society Mortgage Deal Ends

Find the existing fixed or introductory deal end date.
Confirm the contractual follow-on mortgage rate.
Check the lender’s latest published variable rate.
Review your outstanding mortgage balance.
Check the remaining mortgage term.
Calculate the likely new monthly repayment.

Building Society Standard Variable Rate Mortgage FAQs

1. What is a building society Standard Variable Rate mortgage?

A Standard Variable Rate mortgage uses an interest rate set by the building society that can change during the mortgage term. Borrowers commonly move onto an SVR after their fixed, discounted or introductory mortgage deal ends.

2. What happens when my fixed-rate mortgage ends?

Unless a new deal has been arranged, your mortgage normally moves onto the contractual follow-on rate, often the building society’s SVR. Your monthly payments may rise or fall depending on the new rate.

3. Is a building society SVR linked to Bank of England Bank Rate?

Not necessarily. Most SVRs are managed by the lender rather than directly tracking Bank Rate. They may respond to Bank Rate changes, but the movements do not have to be identical. Specific contractual caps or tracker rules may apply to some mortgages.

4. What is Nationwide’s Standard Mortgage Rate?

Nationwide’s published Standard Mortgage Rate is 6.49%, effective from 1 January 2026. Its separate Base Mortgage Rate is published at 5.75%. Confirm current figures and which rate applies to your individual mortgage before acting.

5. Can I leave a Standard Variable Rate mortgage at any time?

Generally yes. Many SVR mortgages have no Early Repayment Charge, so you can usually arrange a product transfer or remortgage. Always check the individual mortgage terms before switching.

6. Are Standard Variable Rate mortgages more expensive than fixed rates?

They are often more expensive than competitive fixed or tracker products, but not always. Compare the interest rate, product fees, Early Repayment Charges, remaining term and flexibility before deciding.

7. Can I make unlimited overpayments on an SVR mortgage?

Many building societies permit unlimited overpayments on their standard variable rates. However, individual mortgage products can contain different restrictions, so check your lender’s conditions before making a large payment.

8. How early should I review my mortgage before the fixed rate ends?

MoneyHelper recommends contacting your existing lender around six months before your deal ends to understand available options. Your building society may have a shorter product-transfer application window.

9. Can I stay on an SVR until the mortgage ends?

Usually yes, provided the mortgage continues under its terms and payments are maintained. The rate can change during that period, and remaining on SVR may cost more than switching to another suitable deal.

10. What should I do if I cannot afford the SVR mortgage payment?

Contact your building society as soon as possible, ideally before missing a payment. Ask about available rate-switching options and mortgage support. MoneyHelper also provides free guidance about rising mortgage costs and finding debt advice.
