How to Improve Your Chances of Getting a Mortgage

Mortgage approval is not random. UK lenders use predictable scoring models. If you know what they're looking for and prepare 6–12 months in advance, you can transform a borderline rejection into a solid approval — and unlock better rates in the process.

For broader context on the full FTB journey, our pillar guide How to get a mortgage as a first-time buyer in the UK walks through the full process. For the credit-score side specifically, see What credit score do you need for a mortgage in the UK?.

The 12-month playbook

If you're planning to buy in 12 months, do these things now.

Month 12 (a year before you apply)

  • Pull all three credit reports (Experian, Equifax, TransUnion) — free
  • Note any errors, defaults, or late payments
  • Register on the electoral roll at your current address
  • Open a Lifetime ISA if you don't have one
  • Set up direct debits for utilities, mobile, and any subscriptions — paid from your main current account

Month 9

  • Pay down credit card balances to under 30% of limit (ideally under 10%)
  • Close store cards and credit cards you don't use that are recent
  • Fix any errors on credit reports (write to the agency)
  • Cancel "buy now pay later" Klarna and Clearpay accounts you don't need

Month 6

  • Stop applying for any new credit (loans, cards, BNPL, car finance)
  • Stay in your current job
  • Build savings habit — regular £200+/month transfer to savings on payday
  • Avoid gambling transactions on your bank statements

Month 3

  • Get all 3 credit reports again, confirm progress
  • Calculate your deposit and check current borrowing capacity with our mortgage calculator
  • Get a free AIP from a broker to confirm what you can borrow
  • Reduce big monthly outgoings (gym, subscriptions you don't use)

Month 1

  • Have 3 months of clean bank statements ready
  • Have 3 months of payslips ready
  • Cancel any unused credit accounts
  • Pay off any final credit card balances if possible

What makes a strong application

Lenders are essentially asking: "Can this person afford the loan, and will they pay it back?" They look at:

Credit profile

  • Pay everything on time
  • Be on the electoral roll
  • Keep credit card utilisation low
  • No defaults / CCJs in last 24 months
  • No recent hard credit applications
  • Long history of accounts in good standing

Income

  • Stable job for at least 6 months (preferably 12+)
  • PAYE preferred over self-employed (though self-employed is fine with 2+ years of accounts)
  • Bonuses / commission documented and ideally consistent over 2 years
  • No recent income drops

Outgoings

  • Low committed monthly expenditure (loans, child support, school fees, etc.)
  • No gambling spend visible on bank statements
  • Reasonable lifestyle spending (lenders look askance at £400/month on takeaways)

Deposit

  • Source clearly evidenced (own savings, gifted with letter, LISA, inheritance)
  • Held in your name for at least 6 months ideally
  • No "round-tripping" (deposit appearing the week before application)

Property

  • Standard construction
  • Lease 80+ years (if leasehold)
  • No cladding or known structural issues
  • Realistic purchase price relative to comparable sales

Common red flags lenders see

  • Recent credit applications — looks like financial distress
  • Gambling transactions — even small amounts. Stop 3 months before applying.
  • Frequent overdraft use — even authorised
  • Direct debits being missed even if reinstated
  • Unexplained large transactions — both deposits and withdrawals
  • Recent change of address with no clear reason
  • Joint accounts with someone of poor credit (creates financial association)
  • Commute pattern — short job tenure plus address far from workplace looks unstable

Things you can fix in 30 days

Some quick wins:

  • Register on the electoral roll
  • Pay down credit card balances under 30%
  • Use Experian Boost — open banking data showing your direct debits, can lift score 20–80 points
  • Pay any outstanding small balances (parking tickets, utility, etc. — these can land on credit files)
  • Build a 3-month "clean" bank statement window with no gambling and steady savings

Things that take 3 months

  • Build payment history on a credit-builder card or low-limit existing card
  • Establish a consistent savings pattern
  • Stop using Klarna and Clearpay (close accounts ideally)
  • Reduce overall credit utilisation across all cards

Things that take 6+ months

  • Recover from missed payments
  • Recover from a fresh default (24+ months minimum for most lenders)
  • Self-employed track record (2 years minimum, 3+ ideal)

What to avoid in the 6 months before applying

  • Taking out a car loan or PCP
  • Opening a new credit card (even 0%)
  • Switching jobs (especially probation)
  • Going self-employed
  • Taking out big BNPL purchases (Klarna, Clearpay)
  • Missing a single payment on anything
  • Applying for any other credit in the 3 months before applying for the mortgage
  • Big lifestyle changes that show in your bank statement (gambling, sudden subscription bursts)

What to do during the application

  • Respond to lender queries within 24 hours
  • Don't apply for any new credit
  • Don't make large unexplained transactions
  • Keep employment stable
  • Keep your name and address consistent across all accounts

After the offer (don't relax yet)

The mortgage offer can be withdrawn before exchange of contracts. Until exchange:

  • Don't change jobs
  • Don't take on new debt
  • Don't make big bank-account moves

After exchange, the offer is locked in. After completion, congratulations — focus on staying on top of payments.

Frequently asked questions

How long do I need to be in my job before applying? Most lenders want 3–6 months minimum, ideally 12+. Some accept new jobs with a confirmed start date and a contract, particularly if it's a salary increase.

Will switching banks improve my chances? No — your bank account history matters less than your credit file and bank statements. Switch only if your current account is causing problems (regular overdraft, fees).

Can I get a mortgage if I'm on probation? Yes, but options narrow. Some lenders require completed probation; others accept it with a strong reference letter from the employer.

Should I tell my lender about my partner's bad credit? If you're applying jointly, the lender will see both credit files anyway. If you're applying solo, theirs is irrelevant unless you have joint accounts together.

Will closing old credit cards help? Mixed effect — closing cards reduces your overall credit limit (raising utilisation %) but also reduces the appearance of "available credit". Generally, keep old cards in good standing open and unused.

Should I pay off my student loan? No — UK student loans are written off after 30 years and the monthly repayment is treated as an outgoing only. Paying off the balance early rarely improves mortgage chances.
