Jargon Buster

Buying a home or arranging protection comes with a lot of unfamiliar language. We have pulled together plain-English explanations of the mortgage and protection terms you are most likely to come across, so nothing catches you off guard. If you hear a term that is not listed here, just ask us and we will be happy to explain it.

Mortgage terms

Agreement in Principle (AIP)

An early indication from a lender of how much they may be willing to lend, based on a light check of your finances. It is not a full offer, but it shows estate agents and sellers that you are a serious buyer.

APRC (Annual Percentage Rate of Charge)

A figure showing the overall yearly cost of a mortgage across its full term, including interest and most fees. It is designed to help you compare deals on a like-for-like basis.

Arrangement Fee (Product Fee)

A charge some lenders apply for setting up a particular mortgage product. You can usually pay it upfront or add it to the loan, though adding it means paying interest on it over time.

Capital

The amount you actually borrow, separate from the interest charged on it.

Repayment Mortgage

A mortgage where each monthly payment covers both interest and a slice of the capital, so the balance steadily reduces and is cleared by the end of the term.

Interest-Only Mortgage

A mortgage where monthly payments cover only the interest. The full amount borrowed is still owed at the end of the term and must be repaid separately, so a credible repayment plan is essential.

Loan to Value (LTV)

The size of your mortgage expressed as a percentage of the property value. A £180,000 loan on a £200,000 home is 90% LTV. Lower LTVs usually unlock better rates.

Deposit

The portion of the purchase price you pay yourself. A larger deposit lowers your LTV and typically gives you access to better deals.

Equity

The share of your property you own outright, the difference between its current value and the mortgage still owed.

Negative Equity

When your property is worth less than the mortgage secured against it.

Fixed Rate

An interest rate that stays the same for a set period, keeping your payments predictable regardless of wider rate movements.

Standard Variable Rate (SVR)

The lender default rate, which a mortgage usually reverts to once an initial deal ends. It can move up or down at the lender discretion.

Tracker Rate

A variable rate that follows the Bank of England base rate at a set margin, so payments rise and fall in line with it.

Discount Rate

A variable rate set at a discount below the lender SVR for an agreed period.

Early Repayment Charge (ERC)

A fee a lender may apply if you repay or overpay beyond agreed limits during a deal period, often a percentage of the outstanding balance.

Overpayment

Paying more than your required monthly amount to clear the balance faster. Most lenders allow a yearly overpayment allowance, commonly up to 10%, without triggering an ERC.

Porting

Transferring your existing mortgage deal to a new property when you move, subject to the lender approval.

Remortgage

Switching your mortgage to a new deal or a new lender, usually to secure a better rate or release equity, without moving home.

Product Transfer

Moving to a new deal with your current lender when the existing one ends, without changing provider.

Term

The total length of time over which the mortgage is repaid, commonly between 25 and 35 years.

Mortgage Offer

The formal, binding confirmation from a lender that they will lend a stated amount on agreed terms, issued once full underwriting is complete.

Valuation

A lender assessment of a property worth to confirm it is adequate security for the loan. This is separate from a more detailed survey you might commission for your own peace of mind.

Conveyancing

The legal process of transferring property ownership from seller to buyer, handled by a solicitor or licensed conveyancer.

Stamp Duty Land Tax (SDLT)

A tax payable on property purchases above certain thresholds in England and Northern Ireland. Rates vary by price, buyer type, and whether you already own other property.

Freehold

Owning both the property and the land it sits on outright, with no time limit.

Leasehold

Owning the right to live in a property for a fixed number of years while someone else owns the land. Ground rent and service charges may apply.

Buy-to-Let

A mortgage for a property you intend to rent out rather than live in. Lending is usually based largely on the expected rental income.

Protection terms

Life Insurance (Term Assurance)

Cover that pays a lump sum if you die within the policy term, helping protect your family or clear the mortgage.

Level Term Assurance

Life cover where the payout amount stays the same throughout the term.

Decreasing Term Assurance

Life cover where the payout reduces over time, often arranged to track a reducing repayment mortgage balance.

Family Income Benefit

Life cover that pays your family a regular income rather than a single lump sum if you die during the term.

Critical Illness Cover

Pays a lump sum if you are diagnosed with one of the serious conditions listed in the policy, such as certain cancers, heart attack, or stroke.

Income Protection

Replaces part of your income if you cannot work due to illness or injury, paying out until you recover, retire, or the policy ends.

Buildings and Contents Insurance

Buildings cover protects the structure of your home and contents cover protects your belongings inside it. Lenders normally require buildings cover to be in place.

Waiver of Premium

An optional add-on that keeps a protection policy running by covering the premiums if you are unable to work through illness or injury.

Writing a Policy in Trust

A legal arrangement that directs who receives a life insurance payout, often speeding up payment and helping keep it outside your estate for inheritance tax purposes.

Underwriting

The process a lender or insurer uses to assess your circumstances and the risk involved before agreeing terms.

Regulatory and general terms

FCA (Financial Conduct Authority)

The UK regulator for financial services firms, including mortgage and protection advisers.

Whole of Market

An adviser able to recommend products from across the available market rather than from a single limited panel.

Broker (Intermediary)

A qualified adviser who searches the market on your behalf and arranges a mortgage or protection plan suited to your circumstances.
