What Credit Score Do I Need to Get a Mortgage in the UK?

Your credit score won’t make or break your mortgage — but it does shape your options. If you’re planning to buy your first home in the UK, you’ve probably come across vague advice about needing a “good” score. But what does that actually mean in 2025?

This guide will walk you through:

What credit scores lenders look for
How credit scores are calculated
What else affects mortgage approval
How to improve your score before applying

We’ll also bust some common myths and share practical tips to increase your chances — without the stress.

How UK Credit Scoring Actually Works

There’s no single UK credit score — and no universal number that guarantees approval. Instead, lenders use credit reference agencies (CRAs) like Experian, Equifax, and TransUnion to assess your financial history. Each agency has its own scale:

Credit Agency	Score Range	“Good” Range
Experian	0–999	881+
Equifax	0–1,000	531+
TransUnion	0–710	604+

These numbers are just guides. When you apply for a mortgage, lenders combine your credit report with affordability checks, your deposit size, job status, and more.

What Credit Score Do Mortgage Lenders Prefer?

Most high-street mortgage lenders prefer scores in the “good” to “excellent” range. While there’s no magic number, here’s a general idea:

Score Tier	Mortgage Options
700+ (Experian)	Excellent approval odds and best rates
600–699	Good chance with a decent deposit
500–599	Might qualify with specialist lenders or higher rates
Below 500	Unlikely without a guarantor or big deposit

But remember — it’s not just the score that matters. Lenders also look at:

Missed or late payments
Defaults or County Court Judgments (CCJs)
Payday loans
Your use of credit (known as “utilisation”)
Financial links with other people (e.g., joint accounts with poor credit)

Can You Get a Mortgage with a Poor or Fair Credit Score?

Yes — but it may be harder, and more expensive.

Poor credit: You may need to go through a specialist mortgage lender. Expect higher interest rates and potentially larger deposits.
Fair credit: Some high-street lenders will consider your application, especially with a solid deposit (10–15%) and stable income.
Guarantor mortgages: In some cases, a family member can support your application.

🧠 Tip: Use a mortgage in principle tool with soft checks (won’t impact your credit score) to see what you might qualify for.

What Else Affects Mortgage Approval?

Credit score is only one part of the puzzle. Lenders also assess:

Factor	Why It Matters
Deposit size	The bigger the deposit, the less risk to the lender
Income	Lenders typically offer 4–4.5x your annual income
Job type	Full-time/PAYE is preferred to variable income
Debt levels	High credit card or loan balances reduce affordability
Spending habits	Large outgoings on subscriptions, loans, or lifestyle can raise red flags

How to Improve Your Credit Score Before Applying

Start preparing 6–12 months before your mortgage application. Here’s how:

✅ Step-by-Step Tips

Check your credit score at all three CRAs:
Register to vote at your current address — this boosts score stability.
Pay bills and cards on time — even mobile or streaming services help.
Keep credit utilisation under 30% — if you have a £1,000 limit, stay under £300.
Avoid new credit applications 3–6 months before applying.
Use credit-building tools like:
- Loqbox — save monthly and build credit
- Experian Boost — adds regular payments to your score

🛠️ Tip: Use Emma to stay under limits, spot due dates, and avoid late fees.

When Is Your Credit Score Checked?

Mortgage in Principle: Usually a soft check — won’t affect your score
Full Application: Hard check — will be visible on your file

📅 Create a mortgage prep timeline:

Timeline	Action
12 months before	Start building credit history
6 months before	Stop new credit applications
3 months before	Run checks, fix errors, pay down debts
1 month before	Check for missed payments or defaults
