How mortgages work in the UK: basics, types and jargon explained

Mortgages let you borrow money to buy a home. The lender holds the property as security while you repay the loan over an agreed term. You normally pay a deposit, then monthly payments that cover interest and, usually, some capital.

Types of mortgages

• Fixed-rate: the interest rate stays the same for a set period (often 2–5 years). Your monthly payment remains steady during that time.
• Tracker: the rate follows the Bank of England base rate plus a set margin. Payments move up or down as the base rate changes.
• Variable / SVR: the lender’s standard variable rate can change at any time. It is often less predictable than a fixed deal.
• Discount and capped-rate deals: temporary offers that reduce the lender’s rate for a set time or cap how high it can go.
• Repayment vs interest-only: repayment mortgages pay both interest and capital, clearing the loan by the end of the term. Interest-only loans only pay interest, so you must plan how to repay the capital.

Key jargon explained

• Loan-to-value (LTV): the loan as a percentage of the property value. Lower LTV usually gives access to better rates.
• Arrangement fee: a one-off charge some lenders add to set up the mortgage.
• Valuation and survey: checks the property’s condition and value. A valuation is basic; a survey is more detailed and can reveal issues.
• Affordability check: lenders review income, bills, and outgoings to decide how much you can borrow.
• APR or APRC: shows the overall cost of the mortgage, including interest and some fees, to help compare deals.

How interest affects payments

Interest is the cost of borrowing. On a fixed deal, your payment stays steady for the fixed term. On tracker or variable deals, payments change with rates. Even a small rise in interest can increase monthly costs, so check how much you could pay if rates go up.

What to check before you apply

• Check your credit score and fix any errors.
• Save for a deposit to lower your LTV and get better offers.
• Compare quotes from several lenders or use a broker to find suitable deals.
• Understand fees, early repayment charges, and any product transfer rules.
• Make sure you can cover future increases in payments in case rates rise.

Saving for a deposit and government schemes (help to buy, shared ownership)

Saving for a deposit is one of the first steps to buying a home. A larger deposit usually means better mortgage rates and lower monthly costs, so setting a clear target helps you plan.

How much deposit do you need?

Most lenders accept from 5% to 20% of the property price. For example, a £200,000 home needs £10,000 (5%) or £40,000 (20%). Lower deposits raise the loan-to-value (LTV) ratio and can limit your deal options.

Practical ways to save

• Create a simple budget to track income and cut non-essential spending.
• Set up a separate savings account and use a standing order to save regularly.
• Use windfalls—bonuses, gifts, tax refunds—directly into your deposit pot.
• Reduce high-interest debt first, as it can block mortgage approval or reduce how much you can save.
• Consider gifts from family, but check lender rules on gifted deposits and get any promise in writing.

Government options that help

Lifetime ISA (LISA): if you qualify, you can save up to £4,000 a year and get a 25% government bonus (up to £1,000 yearly). LISAs have age limits and rules on withdrawals, so read conditions before using one for a home purchase.

Help to Buy equity loans were offered in some parts of the UK but closed to new applicants in England; rules and availability vary across regions. Always check current government guidance to see what local schemes exist today.

Shared ownership explained

Shared ownership lets you buy a share of a home (often 25–75%) and pay rent on the rest. You need a smaller deposit on the share you buy, but you will still pay rent and service charges. Over time you can usually buy more of the property through staircasing.

Checklist before you save

• Check your credit score and fix errors; a better score helps secure lower rates.
• Estimate how much you need for deposit, fees, and moving costs.
• Explore a LISA if eligible, and compare regular savings accounts for interest.
• Speak to a mortgage adviser or broker to understand which schemes you can use.
• Keep clear records of any gifted funds, as lenders will want proof.

Small, consistent actions make a big difference. Plan targets in months, not years, set up automatic savings, and review progress each quarter to stay on track.

Choosing the right mortgage: fixed, variable, tracker and specialist deals

Choosing the right mortgage starts with your budget, plans and comfort with risk. Consider the length of time you expect to stay in the home, your ability to handle payment changes, and any special circumstances like irregular income.

Compare the main deal types

• Fixed-rate: the interest stays the same for a set period (often 2–5 years). This gives payment certainty and suits buyers who want stable monthly costs.
• Tracker: the rate moves with the Bank of England base rate plus a margin. Payments can fall and rise, so this works if you can absorb short-term increases.
• Variable / SVR: the lender’s standard variable rate can change at any time. It is flexible but less predictable and can be high after promotional periods.
• Specialist deals: designed for people with irregular income, self-employment, or low credit scores. They can be more expensive but open options that mainstream deals do not.

Practical factors to weigh

• Check the initial rate and the rate after any introductory period.
• Compare the APRC to see total cost including fees.
• Look for early repayment charges and whether you can make overpayments without penalty.
• Consider portability if you might move house, and product transfer rules when your deal ends.
• Factor in fees: arrangement fee, valuation fee and legal costs can change the true cost.

How to choose for your situation

If you need budget stability, a fixed deal is a safe choice. If you expect rates to fall or plan to remortgage soon, a tracker or short-term variable deal can be cheaper. If you have nonstandard income, talk to a specialist lender or broker to find a tailored option.

Questions to ask before deciding

• What is the projected monthly payment if interest rates rise by 2%?
• Are there penalties for overpaying or repaying early?
• What fees are included in the APRC and which are charged separately?
• How long is the deal term and what happens when it ends?
• Can I add a joint applicant later or transfer the mortgage if I move?

Simple comparison example

Example: a £200,000 mortgage on a 25-year term. A 2.5% fixed deal gives a steady monthly cost. A tracker at base rate +1.5% might start lower, but if the base rate rises by 1.5% your payments could match or exceed the fixed option. Run both scenarios to see the worst-case monthly cost.

Use a broker or a mortgage calculator to test different rates and terms. Keep documents like payslips and bank statements ready so you can get accurate quotes quickly.

Eligibility, affordability checks and improving your mortgage chances

Eligibility for a mortgage depends on several simple facts: your age, residency, income, deposit size and credit history. Lenders use documents to check each point.

What lenders typically check

• Identity and residency: passport or driving licence and proof of address.
• Income: payslips, P60, or tax returns for self-employed applicants.
• Employment status: permanent contracts are viewed more favorably than short-term or variable work.
• Deposit and loan-to-value (LTV): a bigger deposit lowers LTV and can secure better rates.
• Credit history: missed payments, defaults or county court judgments (CCJs) can affect offers.
• Existing debts and outgoings: credit cards, loans, childcare and other monthly costs.
• Property type: some homes need specialist mortgages and extra checks.

How affordability checks work

Lenders calculate how much you can afford by comparing your regular income with your essential outgoings. They then apply a stress test to see if you could still pay if rates rise. This test uses a higher interest rate than your current deal to create a safety margin.

• They check bank statements to confirm income and regular spending.
• They factor in monthly bills, loan repayments and proposed mortgage payments.
• They may include a buffer for future rate rises or higher living costs.

Documents you should have ready

• Recent payslips and P60 or three years’ tax returns if self-employed.
• Bank statements covering at least three months.
• Proof of deposit source and any gifted funds with a written gift letter.
• ID and proof of address, such as a recent utility bill.

Ways to improve your mortgage chances

• Boost your deposit: even a small increase can lower LTV and widen your options.
• Clear or reduce debts: lower monthly outgoings and improve affordability calculations.
• Check and fix your credit report: correct errors and avoid new credit applications before applying.
• Show stable income: long-term employment or consistent freelance earnings help.
• Consider a joint application or a guarantor if your income is low.
• Get a mortgage in principle to show sellers you’re a serious buyer and to get clearer borrowing limits.
• Use a specialist mortgage broker for hard-to-place cases like self-employed applicants or unusual properties.

Start by checking your credit score and gathering documents. Small steps now make it easier to pass affordability checks later.

Step-by-step application process and common mistakes to avoid

Follow these practical steps to complete your mortgage application and avoid common traps that slow the process.

Step-by-step application process

1. Get a mortgage in principle to know how much you can borrow and show sellers you’re serious.
2. Choose a mortgage type and compare quotes from at least three lenders or use a broker to find suitable options.
3. Gather documents: ID, proof of address, recent payslips, P60, three months of bank statements or tax returns if self-employed.
4. Submit the full application with the chosen lender and provide any additional paperwork they request promptly.
5. Arrange a property valuation and, if needed, a more detailed survey to check for issues that could affect the mortgage.
6. Receive the lender’s formal mortgage offer. Read it carefully and check fees, conditions and any special clauses.
7. Instruct your solicitor or conveyancer to handle legal checks, searches and the exchange of contracts.
8. Complete the purchase: on completion day the lender transfers funds, you get the keys and start mortgage repayments as agreed.

Common mistakes to avoid

• Applying without checking your credit score: unresolved errors or recent credit applications can lower your chances.
• Failing to declare all income or outgoings: hidden debts or missing income evidence can lead to a declined application.
• Not considering extra costs: arrangement fees, valuation fees, stamp duty and moving costs affect affordability.
• Making large purchases before completion: new credit or big outgoings can change affordability checks.
• Choosing a mortgage only by the headline rate: compare APRC and factor in fees and early repayment charges.
• Rushing a valuation or skipping a survey: undiscovered property issues can lead to unexpected costs or re-negotiation.

Practical tips to speed up approval

• Organize documents in advance and provide clear, consistent records.
• Use electronic copies for faster review when lenders accept them.
• Keep a record of gifted deposit evidence and a signed gift letter if needed.
• Stay in regular contact with your broker or lender and respond quickly to information requests.
• Consider a broker for complex incomes (self-employed, contractors) to find lenders familiar with your situation.

Final thoughts for first-time buyers

Buying your first home can feel overwhelming, but small steps—saving a deposit, checking your credit, and getting a mortgage in principle—make it manageable.

Compare deals, ask questions about fees and penalties, and consider a broker if your income is unusual. Plan for possible rate rises and keep documents organized to speed up approval.

With clear goals and steady planning, you can improve your mortgage chances and move into your first home with confidence.
