Building Society Mortgage Rates UK 2026: Compare Deals

Building society mortgage rates in September 2026 vary sharply by deposit, loan-to-value (LTV), deal length, mortgage purpose and product fee. Current official examples include two-year fixes below 5% at lower LTVs, while 90% and 95% LTV borrowers generally face higher pricing.

The useful comparison is not “which building society has the lowest percentage?” It is which deal fits your LTV and borrowing purpose after the product fee, cashback, valuation or legal incentives, Early Repayment Charges and follow-on rate are included.

What this snapshot shows: lower-LTV borrowers are generally seeing cheaper headline rates than 90–95% LTV borrowers. But the lowest rate often carries a product fee, so borrowers with smaller balances should compare the fee-paying and fee-free versions carefully.

How LTV Changes Building Society Mortgage Rates

Loan-to-value is the percentage of the property’s value you need to borrow. A £20,000 deposit on a £200,000 purchase means borrowing £180,000, which is 90% LTV.

60–75% LTV More equity, wider pricing choice

Borrowers with larger deposits or more home equity often have access to a lender’s lower-priced mainstream fixed deals.

80–85% LTV Middle LTV range

Rates can remain competitive, but product fees and maximum loan sizes begin to differ more between societies.

90% LTV 10% deposit or equity

Pricing is generally higher than at 75–80% LTV. Cashback and fee-free alternatives become particularly important to compare.

95% LTV 5% deposit

Useful for eligible first-time buyers and movers with smaller deposits, but rates and affordability tests are usually tighter.

98% LTV Specialist low-deposit products

A few building societies offer specialist products above 95% LTV. Newcastle’s current First Step range includes lending up to 98% LTV, subject to its criteria.

Do not assume adding £1 to the deposit changes the rate. Mortgage pricing normally changes at defined LTV bands. If you are close to the next threshold—such as 90%, 85% or 75%—ask how much extra deposit would be needed to enter the lower band and whether the rate difference justifies it.

2 Year vs 5 Year Fixed Mortgage: Which Comparison Matters?

2-year fixed rate

  • Shorter period of payment certainty.
  • You can review the market sooner.
  • Useful if your circumstances may change within a few years.
  • You may face another product fee and remortgage process sooner.
  • You are exposed sooner if mortgage rates are higher when the deal ends.

5-year fixed rate

  • Longer period of predictable monthly payments.
  • Fewer refinancing decisions during the fixed period.
  • Can suit borrowers prioritising certainty.
  • ERCs may apply for much longer.
  • You may remain tied to the deal if market rates fall significantly.
Do not decide from the rate difference alone. If you may move house, repay a large lump sum or change the mortgage within three years, a five-year fix with a long ERC schedule can be less flexible even if its initial rate looks attractive.

Mortgage Rate vs Product Fee: Why the Lowest Rate Can Cost More

Building societies commonly offer two versions of a similar mortgage: one with a lower interest rate and a product or completion fee, and another with no fee but a higher rate.

Example

Balance size matters. A fixed £999 fee has proportionally more impact on a smaller mortgage than a much larger mortgage. Compare the total cost over the fixed period rather than automatically choosing the lower rate.

First-Time Buyer Mortgage Rates: 90% and 95% LTV

First-time buyers with a 5% or 10% deposit typically focus on 95% or 90% LTV deals. Rate is important, but affordability, gifted-deposit rules, product fees, cashback and the maximum loan calculation can be just as decisive.

95% LTV example West Brom currently displays a 2-year fixed 95% LTV product at 5.32% with a £499 completion fee.
Newcastle 95% range Its live finder currently shows standard 2-year 95% fixed examples around 5.50% with a £999 fee and 5.60% with no fee.
Nationwide 95% lending Nationwide continues to offer fixed-rate products up to 95% LTV. Its live rate finder should be checked because current pricing is dynamic.
High LTV affordability A 5% deposit does not guarantee a 95% mortgage. Income, outgoings, credit history and property acceptability still apply.

  3. Compare fee-paying and no-fee versions.
  4. Read the ERC schedule.
  5. Check the maximum loan and affordability criteria before treating the displayed rate as available to you.

Building Society Remortgage Rates: Compare More Than the New Rate

Remortgaging means replacing your existing mortgage with a mortgage from a different lender. Before moving, compare the saving from the new rate against any ERC from your existing mortgage and the costs or incentives attached to the new deal.

Current mortgage balance.
Existing deal end date.
Current Early Repayment Charge.
Estimated current property value.
Resulting remortgage LTV.
New product fee.
Valuation cost or free valuation benefit.
Legal or fee-assisted conveyancing.
Cashback.
New ERC schedule.
Legal-assisted does not necessarily mean every legal cost is covered. Check what the lender’s remortgage solicitor package includes and whether additional work—such as leasehold issues, transfer of equity or complex title work—creates extra charges.

Fixed Rate vs Tracker Mortgage in 2026

Fixed mortgage

  • Interest rate is fixed for the initial deal period.
  • Monthly payments are predictable during that period.
  • You do not benefit immediately if Bank Rate falls.
  • ERCs commonly apply.

Tracker mortgage

  • Usually follows Bank Rate plus a set margin.
  • Payments can rise or fall.
  • Some tracker products have no ERC.
  • A rate floor or collar can limit how far the rate falls.

Skipton’s current mortgage finder includes two-year residential tracker products and explains that some are priced as Bank Rate plus a margin, with a floor. Yorkshire Building Society also currently offers tracker mortgages and warns that payments rise when Bank Rate rises.

Official SkiptonSkipton Mortgage Finder

After opening this link:

  1. Enter whether you already have a Skipton mortgage.
  2. Select the reason for borrowing.
  3. Enter property value and mortgage amount so the finder can calculate LTV.
  4. Compare fixed and tracker options if both are available.
  5. For trackers, read the Bank Rate margin and any rate floor.
  6. Check whether an ERC applies.

Existing Building Society Mortgage Customers: Switch or Remortgage?

If your mortgage is already with a building society, switching to a new product with the same lender can be simpler than remortgaging elsewhere. A product transfer may avoid legal work and a full new mortgage application, but convenience does not guarantee the lowest total cost.

Yorkshire Building Society YBS currently lets eligible existing borrowers choose a new deal around 120 days before their existing deal ends.
YBS lower-rate option If YBS later offers a lower like-for-like rate, eligible borrowers can currently switch again up to two weeks before the new deal starts.
Newcastle Its existing-customer range can avoid new credit checks and underwriting for a straightforward product switch where no additional changes are requested.
Nationwide Existing members can use its rate finder for switching an existing deal, with current switcher pricing shown through the personalised finder.
Compare before accepting. A product transfer can be quicker, but check suitable remortgage alternatives before locking in. Equally, a slightly lower external rate may not be worth moving for if fees, conveyancing and the existing ERC outweigh the saving.

Early Repayment Charges and Overpayment Rules

The ERC matters if you sell, remortgage, repay the mortgage or overpay more than the lender permits during the fixed period. A five-year mortgage usually exposes you to an ERC schedule for longer than a two-year fix.

West Brom Current two-year products typically show a reducing ERC schedule through the fixed period. Its pages also state an allowance for regular overpayments below £1,000 per calendar month on the displayed deals.
Skipton Where an ERC applies, Skipton’s current finder says overpayments of up to 10% of the original balance per year are generally permitted without an ERC.
Leeds Current residential product information refers to 10% annual capital repayments without an ERC on relevant fixed-rate products.
Planning to move? Check whether the mortgage is portable, but do not assume porting is automatic. The new property and borrowing normally need to meet the lender’s current criteria.

Bank of England Rate: Why Mortgage Pricing Is Volatile in 2026

The Bank of England held Bank Rate at 3.75% on 17 September 2026. The Monetary Policy Committee voted 6–3 to hold, with three members preferring an increase to 4%.

The Bank also reported that quoted two-year fixed mortgage rates were around 95 basis points higher than before the latest Middle East energy shock. That helps explain why mortgage prices can move sharply even when Bank Rate itself has not changed.

Fixed mortgages do not track Bank Rate one-for-one. Lenders also price fixed mortgages using wholesale funding and swap-market expectations, competitive demand, credit risk and their own funding needs.

How to Compare Building Society Mortgage Deals Properly

  1. Work out your mortgage purpose: first purchase, home move, remortgage or existing-customer switch.
  2. Calculate the LTV using a realistic property value and the amount you need to borrow.
  3. Compare products in the same LTV band.
  4. Compare the initial interest rate and fixed or tracker period.
  5. Add the product fee, booking fee and other unavoidable mortgage charges.
  6. Check cashback, free valuation or fee-assisted legal benefits.
  7. Read the ERC schedule and permitted overpayment amount.
  8. Check the follow-on SVR or variable rate.
  9. Review the APRC, but also calculate the cost over the period you realistically expect to keep the deal.
  10. Confirm affordability, maximum loan and property criteria before relying on the displayed rate.
Best comparison habit: save the product illustration or mortgage offer showing the rate, fee, monthly payment, APRC, ERC and deal-end date. A lender’s public rate page can change after you apply.

Building Society Mortgage Rates FAQs

1. What are building society mortgage rates in the UK in September 2026?

Rates vary by lender, LTV, deal length and fee. Selected current examples checked for this guide include West Brom at 4.68% for a two-year 75% LTV fix with a £999 fee, Newcastle at 4.90% for a two-year 80% LTV fix with a £999 fee, and Leeds at 5.19% for a two-year 90% LTV legal-assisted fix with a £999 fee. Rates can change quickly.

2. Which building society has the lowest mortgage rate?

There is no single lowest building-society rate for every borrower. The answer changes with your LTV, mortgage purpose, fixed period, loan size, product fee and eligibility. Compare products in the same category rather than comparing unrelated headline rates.

3. Are 95% building society mortgages available in 2026?

Yes. Several building societies currently offer qualifying 95% LTV mortgages. West Brom and Newcastle both show current 95% fixed-rate products, while Nationwide also offers mortgage ranges up to 95% LTV. Full affordability and lending criteria apply.

4. Is a two-year or five-year fixed mortgage better?

Neither is automatically better. A two-year fix gives you an earlier opportunity to review the market, while a five-year fix provides longer payment certainty. Consider how long you expect to stay in the property, ERCs, product fees and your tolerance for future rate changes.

5. Should I choose a mortgage with a product fee?

A fee-paying mortgage can have a lower interest rate, but the fee may outweigh the saving for some loan sizes. Compare the total cost over the fixed period against the lender’s no-fee alternative.

6. What is LTV on a mortgage?

LTV means loan-to-value. It is the mortgage amount divided by the property’s value. For example, borrowing £180,000 on a £200,000 property is 90% LTV. Lower LTV bands often have access to cheaper mortgage pricing.

7. Is a tracker mortgage cheaper than a fixed mortgage in 2026?

Some current tracker products have lower initial rates than fixed products, but tracker payments can rise if Bank Rate rises. Check the margin above Bank Rate, any rate floor and whether Early Repayment Charges apply before comparing it with a fixed mortgage.

8. When should I start looking for a remortgage?

Start before the current deal expires so you have time to check your ERC, property value, LTV and new-lender options. Existing lenders can also allow product switches several months before the deal ends; the exact window differs by lender.

9. What is the Bank of England interest rate in September 2026?

The Bank of England held Bank Rate at 3.75% on 17 September 2026. Fixed mortgage rates do not move directly with Bank Rate because market expectations, wholesale funding costs and lender pricing also influence them.

10. What should I compare besides the mortgage interest rate?

Compare the product fee, APRC, monthly repayment, LTV, Early Repayment Charges, overpayment allowance, valuation or legal incentives, cashback, maximum loan, follow-on rate and whether the mortgage fits your circumstances and property.
