What is a CIS mortgage?

CIS stands for Construction Industry Scheme, which is a UK government-run scheme that exists to ensure that subcontractors in construction pay the right amount of tax. Any subcontractor working in construction who earns more than £120 a week must register as an employee, otherwise they could be liable to pay back any tax to HMRC (Her Majesty’s Revenue and Customs).

Working on a CIS basis, you have a payslip with a basic 20% deduction for tax, then it is your responsibility to submit annual accounts to HMRC which will then show your net profit, upon which tax and national insurance is calculated. From a lenders point of view this is generally treated as a mortgage for someone who is self-employed, which then means that you will need to have two years accounts, and the amount lent will be based upon your net profit. There are though some lenders who will treat you as being ‘employed’ for income purposes, and work off the gross payslips received, and they will not require two years track record. The difference between what lenders will lend on both can be significant.

Why CIS Contractor Mortgages Are Different

If you’re a CIS contractor, the challenge in securing a mortgage is rarely how much you earn.

It’s how lenders choose to assess that income.

Most high street lenders are set up for traditional, salaried employees. When your income comes from weekly CIS tax vouchers, day rates, umbrella company payslips, or a limited company structure, it often doesn’t fit their standard criteria.

This can lead to:

• Being told you can borrow far less than you realistically can
• Requests for accounts or documents you may not yet have
• Or even being declined, despite strong earnings and a consistent contract history

The issue is that CIS income isn’t always straightforward on paper. Day rates, fluctuating payslips, holiday pay, deductions, and income routed through a limited company can all be misunderstood or undervalued.

To the wrong lender, this complexity looks like risk — even when your income is stable and predictable.

Meanwhile, employed applicants with similar earnings are often assessed more easily, simply because their payslips follow a familiar format.

Choosing the wrong lender can result in wasted time, unnecessary stress, and a declined application that sets you back in your property journey.

A Smarter Way to Assess CIS Contractor Income

At Premier Mortgage Services, we take a different approach.

We specialise in working with CIS contractors and understand how your income works in the real world — whether you’re paid via an umbrella company, your own limited company, or through weekly or monthly CIS tax vouchers.

More importantly, we know which lenders are experienced in assessing contractor applications properly.

Rather than forcing your income into criteria that doesn’t fit, we:

• Start with your contract and day rate
• Convert this into a realistic borrowing potential
• Match you with lenders who understand CIS income

This approach ensures your application is positioned correctly from the start — helping to reduce delays, avoid unnecessary declines, and remove uncertainty.

In many cases, lenders can base your borrowing on your day rate rather than being limited by salary, dividends, or company profits.

This can significantly increase your borrowing potential, without needing to restructure your income or withdraw additional funds from your business just to meet standard lending criteria.
