This guide answers every common UK mortgage question in one place — from how mortgages work and how much deposit you need, to mortgage in principle, bad credit mortgages, broker costs, rate predictions for 2026, and specialist products like lifetime and offset mortgages. What Is a Mortgage and How Does It Work?Quick Answer What is a mortgage?A mortgage is a loan secured against your property. You borrow money from a lender to buy a home, then repay it over a fixed term (typically 25–30 years) with interest. If you stop making repayments, the lender can repossess and sell your home to recover the debt. Quick Answer How does a mortgage work?You pay a deposit (typically 5–20% of the property price), and the lender provides the rest as a mortgage. Each monthly repayment covers interest plus a portion of the capital (on a repayment mortgage). At the end of the term, you own the property outright. The interest rate can be fixed or variable.
Quick Answer How is mortgage interest calculated?Mortgage interest is calculated daily on your outstanding balance. For a £200,000 mortgage at 4.5% annual interest: £200,000 × 4.5% ÷ 12 = £750/month interest in month one. As you repay capital, the balance falls and so does the interest portion of each payment. Your lender provides an annual mortgage statement showing the breakdown. Types of Mortgage Explained
Quick Answer What is a tracker mortgage?A tracker mortgage has an interest rate set at a fixed margin above the Bank of England base rate. For example: base rate (4.25% in April 2026) + 1% margin = 5.25% tracker rate. If the Bank of England cuts rates, your monthly payment falls automatically. If rates rise, your payment rises. No early repayment charges on most trackers. Quick Answer What is an interest only mortgage?On an interest only mortgage, your monthly payment covers only the interest — not the capital. At the end of the term, you still owe the full original loan amount and must repay it in full. You need a credible repayment vehicle (savings, ISA, pension, or sale of the property). Most residential interest only mortgages now require very high equity or income. Common for buy to let. Quick Answer What is an offset mortgage?An offset mortgage links your savings account to your mortgage. You pay interest only on the difference between your mortgage balance and your savings. Example: £200,000 mortgage, £30,000 savings = you pay interest on £170,000 only. Effective if you have significant savings but want flexibility to access them. Quick Answer What is a lifetime mortgage?A lifetime mortgage is a form of equity release for homeowners aged 55+. You borrow against your home's value without monthly repayments — interest rolls up and the loan plus interest is repaid when you die or move into long-term care. It reduces the value of your estate. Only available through FCA-regulated equity release advisers. Quick Answer What is a second charge mortgage?A second charge mortgage is a secured loan taken out against a property you already have a mortgage on. It sits behind the first mortgage in priority. Often used for home improvements or debt consolidation when remortgaging is not cost-effective due to early repayment charges. Higher rates than first charge. How Much Deposit Do You Need for a Mortgage?Quick Answer How much deposit do you need for a mortgage?The minimum deposit for most residential mortgages in the UK is 5% of the property purchase price. On a £250,000 property, that is £12,500. However, rates improve significantly at 10%, 15%, and 25% deposits. A 5% deposit means a 95% LTV mortgage — the most expensive tier. A 25% deposit (75% LTV) gets the best rates.
Rates indicative as of April 2026. Verify current rates at kaeltripton.com/best-remortgage-deals-uk/ or directly with lenders. Quick Answer Can you get a mortgage with no deposit?Not through mainstream lenders. A 5% deposit is the standard minimum. The only zero-deposit route is via a guarantor mortgage (a family member offers their property or savings as security) or through specific schemes. Skipton Building Society launched a 100% Track Record Mortgage in 2023 for renters, but availability is limited and eligibility criteria are strict. Quick Answer Can stamp duty be added to a mortgage?No — mainstream lenders will not add stamp duty to your mortgage. Stamp duty must be paid separately, usually within 14 days of completion. However, you can factor stamp duty costs into your overall budget when calculating how large a deposit to save. Some buyers reduce their deposit to cover stamp duty — this increases LTV and typically worsens your mortgage rate. How Much Can You Borrow?Quick Answer How many times salary for a mortgage?Most lenders offer 4–4.5 times your annual gross salary. On a £50,000 salary, that means borrowing £200,000–£225,000. Some lenders offer up to 5–6 times salary for high earners or professionals (doctors, lawyers, architects). The exact amount depends on your outgoings, credit score, and the lender's affordability assessment.
Joint mortgages: Most lenders use the primary applicant's income for the multiplier, then add a portion of the second applicant's income. Some use total combined income × 4. A mortgage broker can identify which lender's formula gives you the highest borrowing amount for your specific situation. Quick Answer What do you need to get a mortgage?To apply for a mortgage you typically need: proof of identity (passport/driving licence), proof of address (utility bill, bank statement), 3–6 months' payslips or 2–3 years' accounts if self-employed, 3–6 months' bank statements, details of existing debts and outgoings, and information on the property you are buying. A clean credit file significantly helps. Quick Answer What stops you getting a mortgage?Common reasons for mortgage refusal: poor credit history (missed payments, defaults, CCJs, IVA), too much existing debt relative to income, insufficient deposit, being self-employed with inconsistent income, the property being unmortgageable (non-standard construction, short lease, flood risk), or failing the lender's affordability stress test. A mortgage broker can identify which lenders are most likely to accept your application before you apply. Quick Answer What credit score do I need for a mortgage?There is no universal minimum credit score for a mortgage in the UK. Each lender sets its own criteria. Mainstream lenders (Halifax, Nationwide, Barclays) typically want a good or excellent score. Specialist lenders can work with fair or even poor scores but charge higher rates. Check your score free at Experian, Equifax or TransUnion before applying. Mortgage in Principle ExplainedQuick Answer What is a mortgage in principle?A mortgage in principle (MIP) — also called an Agreement in Principle (AIP) or Decision in Principle (DIP) — is a certificate from a lender confirming they would lend you a specific amount, based on a credit check and basic affordability assessment. It is not a formal mortgage offer but shows estate agents and sellers you are a serious buyer. Quick Answer How long does a mortgage in principle last?A mortgage in principle typically lasts 60–90 days. After this, it expires and you need to reapply. Reapplying usually involves another credit check. If your circumstances have not changed, a new MIP is straightforward. Most lenders offer instant decisions online. Quick Answer Does a mortgage in principle affect your credit score?It depends on the type of check. A soft search MIP does not affect your credit score — only you can see it. A hard search MIP leaves a footprint on your credit file visible to other lenders. Too many hard searches in a short period can reduce your score. Ask your lender or broker which type of search they use before applying. Quick Answer How reliable is a mortgage in principle?A mortgage in principle is a strong indicator but not a guarantee. Full mortgage approval requires a detailed affordability assessment, full credit check, property valuation, and legal checks. Reasons an MIP might not convert to a full offer: the property fails valuation, your circumstances change, or the full application reveals issues not found at MIP stage.
How Long Does a Mortgage Application Take?Quick Answer How long does a mortgage application take?A full mortgage application typically takes 2–6 weeks from submission to formal mortgage offer. The main variables are: lender processing times (some are faster than others), how quickly your solicitor completes legal checks, how complex your financial situation is, and whether the property valuation raises any issues. Straightforward applications with a major lender can complete in as little as 2 weeks.
Quick Answer How long does a mortgage application take through a broker?Using a mortgage broker does not significantly change the lender's processing time, but a good broker submits a cleaner, better-prepared application that is less likely to be queried or delayed. Brokers also know which lenders are currently fast at processing, which can save 1–2 weeks. How Long Does a Mortgage Offer Last?Quick Answer How long does a mortgage offer last?A formal mortgage offer typically lasts 3–6 months from the date of issue. Most high street lenders offer 6 months. If you have not completed your purchase by the expiry date, you need to ask your lender for an extension — most will grant one if the delay is not your fault. Remortgage offers typically last 3–6 months.
If your purchase is delayed and your offer is about to expire, contact your lender immediately. Most will extend by 1–3 months, especially if the delay is due to a slow chain or solicitor issues. Do not let it expire without asking — you should not need to reapply from scratch in most cases. Getting a Mortgage With Bad CreditQuick Answer Can you get a mortgage with bad credit?Yes — but your options and rates depend on the type and severity of the credit issue. A missed payment from 3 years ago has far less impact than a bankruptcy last year. Specialist lenders (Pepper Money, Precise Mortgages, Together Money) cater specifically for applicants with adverse credit. Expect higher rates and larger deposit requirements. A whole-of-market broker is essential for adverse credit applications.
Quick Answer Can you get a mortgage with a CCJ?Yes, but it is harder. A satisfied CCJ that is more than 3 years old may be accepted by some mainstream lenders. An unsatisfied CCJ or one registered in the last 12 months will typically require a specialist lender. The CCJ amount, how recently it was registered, and whether it has been satisfied all affect your options. A whole-of-market broker can identify which lenders are most likely to accept your specific situation. Quick Answer Can you get a mortgage with an IVA?Getting a mortgage during an active IVA is extremely difficult — most lenders will refuse. After an IVA is completed (typically after 5–6 years), specialist lenders may consider an application with a larger deposit (25%+). Mainstream lenders typically want 3–6 years clear after IVA completion. Always use a specialist adverse credit broker for IVA mortgage applications. Quick Answer Can I get a mortgage at 60?Yes. There is no upper age limit for taking out a mortgage, but lenders set maximum ages at the end of the term. Most lenders allow repayment up to age 70–75; some specialist lenders allow up to 85 or 90. At 60, a 15-year mortgage term is typically possible with mainstream lenders. Pension income, rental income and investments are all considered by lenders for older borrowers. Quick Answer Can I get a mortgage on benefits?Yes, but it is more difficult. Some lenders accept benefits as income including DLA/PIP, Carer's Allowance, and some working tax credits. Child benefit is also sometimes counted. Universal Credit and other means-tested benefits are rarely accepted as standalone income. You typically need a deposit of at least 10–15% and a good credit history. What Does a Mortgage Broker Do?Quick Answer What does a mortgage broker do?A mortgage broker (also called a mortgage adviser) searches the market on your behalf to find the most suitable mortgage for your circumstances. They assess your income and outgoings, advise on which lenders are most likely to approve you, prepare and submit your application, and liaise with lenders until completion. Whole-of-market brokers search all available lenders; tied brokers only offer products from specific lenders. Quick Answer How much does a mortgage broker cost?Many mortgage brokers charge no fee to the borrower — they earn a commission from the lender (proc fee). Fee-charging brokers typically charge £300–£999 as a flat fee, or 0.3–1% of the mortgage amount. On a £250,000 mortgage, 0.5% = £1,250. Always ask upfront whether the broker is fee-free or fee-charging, and what the total cost is. Fee-charging brokers are not necessarily better than fee-free ones.
Will Mortgage Rates Go Down in 2026?Quick Answer Will mortgage rates go down in 2026?The Bank of England base rate was 4.25% in April 2026, down from a peak of 5.25% in 2023. Most market forecasters expect 1–2 further cuts in 2026, potentially bringing the base rate to 3.5–4.0% by end of 2026. Fixed mortgage rates have already priced in some expected cuts. Whether to fix now or wait depends on your risk tolerance and how long you plan to stay in your current deal. Quick Answer Should I fix my mortgage?If you value payment certainty, fix your mortgage. If you think rates will fall significantly, a tracker with no early repayment charge gives flexibility. In April 2026, 5-year fixed rates offer more certainty than 2-year fixes but lock you in longer. A mortgage broker can model which option saves you more based on your specific balance and term. Quick Answer How long should I fix my mortgage for?A 2-year fix offers flexibility to remortgage sooner if rates fall further. A 5-year fix locks in today's rate for longer — good if you believe rates will rise or stay high. A 10-year fix gives maximum certainty but comes with very high early repayment charges. In April 2026, many borrowers are choosing 2–3 year fixes to retain flexibility as the rate cycle continues down.

Should You Overpay Your Mortgage?Quick Answer Should I overpay my mortgage?Overpaying your mortgage reduces your balance faster, cuts total interest paid, and shortens your term. It is most beneficial when your mortgage rate is higher than the interest you could earn on savings. With mortgage rates above 4% and savings rates around 4–5%, the maths is close — but overpaying is risk-free and guaranteed, whereas savings rates can fall. Check your overpayment allowance first — most lenders allow up to 10% of the outstanding balance per year without early repayment charges. Quick Answer How much can I overpay on my mortgage?Most mortgage products allow overpayments of up to 10% of the outstanding balance per year without triggering early repayment charges (ERCs). On a £200,000 mortgage, that is £20,000/year. Some lenders allow unlimited overpayments on tracker mortgages. Overpay more than the allowance and you may face ERCs of 1–5% of the excess amount.
Use the kaeltripton.com mortgage calculator to model exactly how much interest you save and how many years you knock off your term with different overpayment amounts. Stamp Duty and MortgagesQuick Answer Can stamp duty be added to a mortgage?No. Mainstream UK mortgage lenders will not include stamp duty in the mortgage. Stamp duty must be paid in cash, usually within 14 days of completion. You need to budget for it separately alongside your deposit and legal fees. If you reduce your deposit to fund stamp duty, your LTV increases and you get worse mortgage rates.
Stamp duty rates correct as of April 2026 for England. Scotland and Wales have separate land taxes. Always verify at gov.uk/stamp-duty-land-tax before completing a purchase. Specialist Mortgages ExplainedQuick Answer What is a mortgage deed?A mortgage deed is the legal document you sign when taking out a mortgage. It is a binding contract between you and the lender that creates a legal charge over your property. It records the amount borrowed, interest rate, term, and repayment conditions. The deed is registered at HM Land Registry and means the lender has a secured interest in your property. Quick Answer What is mortgage protection insurance?Mortgage protection insurance (also called mortgage payment protection insurance or MPPI) covers your mortgage repayments if you cannot work due to accident, sickness, or involuntary redundancy. It is different from life insurance — it pays your mortgage while you are alive but unable to work. Most policies pay out for up to 12–24 months. It is optional but worth considering if you have no sick pay or income protection through your employer. Quick Answer Is a mortgage haram?Conventional mortgages with interest (riba) are considered haram (forbidden) in Islamic finance. However, Sharia-compliant alternatives exist in the UK — including Home Purchase Plans (HPPs) offered by providers like Al Rayan Bank and Gatehouse Bank. These use a diminishing musharakah structure where the bank and buyer co-own the property and the buyer buys the bank's share gradually, paying rent on the bank's portion instead of interest. Quick Answer How does part exchange work with a mortgage?Part exchange (PX) is when a housebuilder accepts your existing home as part-payment for a new build property. The builder gives you a guaranteed price for your home, you use that equity as your deposit, and you take a mortgage on the remainder. Part exchange removes the need to sell your home first but you typically get 5–10% less than open market value for your existing property.
