Mortgage with 1 year of accounts
You can get a mortgage with only one year of accounts in the UK. Several lenders accept a single complete year of certified accounts or one year of HMRC tax calculations, as long as the income is evidenced and the rest of the case is sound. The pool of lenders is smaller than with two or three years, so the key is going to one whose criteria explicitly allow a single year.
Why one year is treated differently
Lenders like a track record because it shows income is durable. With one year, they have less history to lean on, so cautious lenders ask for two or three. But "self-employed needs three years" is a myth: it is a common policy, not a rule. Plenty of lenders accept one year, and the trick is simply to apply to one of them rather than to a lender whose minimum is higher.
What makes a one-year case strong
- A full, certified first year of accounts, or a complete SA302 and tax-year overview.
- Business bank statements showing trading has continued since the year-end.
- A relevant background: many lenders are more comfortable if you were employed in the same field before going self-employed.
- A clean credit history and a normal deposit, so the income is the only unusual feature.
Where it falls down
The application usually fails not because one year is impossible, but because it went to the wrong lender. Apply to a high-street bank with a two-year minimum and you are declined on policy, regardless of how good the year was. That decline can also leave a credit footprint. This is exactly the situation where a broker who knows which lenders accept one year saves you both a rejection and wasted time.
Common questions
Can I really get a mortgage with one year of accounts?
Yes. A number of UK lenders will consider a self-employed applicant with a single complete year of accounts or one year of tax calculations, provided the income is evidenced and the wider case is sound. It is a smaller pool of lenders than for two or three years, but it is a real and established option.
What will the lender want to see?
Typically your first full year of certified accounts or your SA302 tax calculation and tax-year overview for that year, plus business bank statements. Some lenders also like to see that the business is continuing to trade at a similar level since the year-end.
Will I be offered worse rates?
Not automatically. With a mainstream lender that simply accepts one year, you may get standard rates. If only a specialist lender fits your case, the rate can be a little higher. The difference narrows once you have more years behind you and can remortgage.
What if my first year was unusually low or high?
Lenders look at whether the figure is representative. A very low first year (start-up costs) or a one-off spike can both prompt questions. Explaining it, with the accountant's help, often matters as much as the number itself.
