Buying your first home in London is exciting, but it can also feel overwhelming. The property market moves fast, prices are high, and if you’re an entrepreneur, the paperwork can be even more complex. One of the most important steps in the process is getting your documents ready for a mortgage application.
In this post, created in collaboration with Step by Step Financial Solutions and Polish Business Link, we’ll guide you through the key documents you’ll need — whether you’re employed or running your own business.
Why Documents Matter
Lenders want to be confident that you can pay back the money you borrow. The documents you provide are their way of checking your identity, your income, and your financial stability. Missing or incomplete paperwork can delay your mortgage approval — or even cause your application to be rejected.
Being prepared saves time and gives you an edge in London’s competitive housing market.
The Basic Checklist for All Buyers
No matter who you are, lenders will usually ask for the following:
-
Proof of ID – passport or driving licence.
-
Proof of Address – utility bill, council tax statement, or recent bank statement.
-
Bank Statements – usually the last 3–6 months.
-
Credit Report – showing your borrowing history and repayments.
These documents confirm who you are, where you live, and how you handle your money.
Extra Documents If You’re Employed
If you’re a salaried employee, lenders typically want:
-
Your last 3–6 months of payslips.
-
Your P60 (annual summary of pay and tax).
This gives them a clear picture of your income and job stability.
Extra Documents If You’re an Entrepreneur or Self-Employed
For business owners, contractors, or freelancers, the process is more detailed. Lenders want to see proof that your business generates steady income. You may need:
-
2–3 years of business accounts (prepared by a certified accountant).
-
SA302 tax calculations (from HMRC).
-
Tax year overviews.
-
Business bank statements.
Some specialist lenders will also consider retained profits in your company. The stronger and clearer your financial records, the easier it is to secure approval.
