CIS Mortgage
Michal Iwinski explains Construction Industry Scheme (CIS) mortgages.

What is a CIS mortgage and how does it work?
A CIS mortgage is a standard mortgage where a self-employed person who’s in the Construction Industry Scheme (CIS) can use gross CIS payments to prove their income, rather than full business accounts.
It can be beneficial for those with less than two years of business accounts, or who prefer to show their income as a gross figure.
Who is eligible for a CIS mortgage?
To be eligible for a CIS mortgage you must be a self-employed worker in the construction industry, that’s the first thing – and specifically be paid through the CIS.
This includes tradespeople and other individuals who work in the broader construction sector, even if they aren’t directly involved in physical construction – such as architects.
Essentially, you need to be registered with the CIS and have your tax deducted at source by your main contractor.
Can self-employed workers apply for a CIS mortgage?
Basically, yes, self-employed individuals working within the construction industry and paid through the CIS can apply. These mortgages are specifically designed to cater to the unique income verification needs of CIS subcontractors.
While self-employed individuals typically need to provide accounts and tax returns, CIS mortgages can often rely on payslips and bank statements to verify your income.
What are the benefits of a CIS mortgage compared to a regular mortgage?
A CIS mortgage offers the benefit of using your gross income for affordability calculations, potentially allowing you to borrow more compared to traditional self-employed mortgages, which use net income.
Additionally, a CIS mortgage may require less paperwork and have shorter application timelines, simplifying the whole process.
How much employment history do you need for a CIS mortgage?
Most lenders require proof of income and at least three months of continuous CIS payments into your bank account. Some lenders might want to see 12 months of CIS payslips or bank statements to verify your income.
Additionally, you may need to demonstrate that you have been working in the construction industry for at least 12 months.

How do the interest rates and fees associated with a CIS mortgage compare to those of a traditional mortgage?
In most cases, interest rates and fees for a CIS mortgage are the same as those of a traditional mortgage. There’s no extra charge or any disadvantages for CIS workers on rates or fees, which is a good thing.
What documents are required to apply for a mortgage as a CIS worker?
You typically need to provide proof of your income with CIS invoices or payslips, and bank statements showing the income. You will also need standard identification documents.
Some lenders may also require proof of your deposit, and potentially a letter of confirmation from your contractor.
How can someone find a reputable lender who offers CIS mortgages?
It’s difficult, because this changes all the time. It’s particularly challenging to find the right bank that’s favourable to a CIS situation. Having a mortgage broker is really key – and more specifically, one who specialises in CIS mortgages.
Are there any other unique features or requirements of a CIS mortgage that borrowers should be aware of?
While similar to traditional mortgages, there are some unique aspects for borrowers, particularly regarding income assessment and documentation. Borrowers should be aware of potential deposit requirements, the importance of credit history and the need for clear documentation to prove their income.
How can a mortgage broker help? Is there anything else you’d like to add?
We recommend that you speak with a mortgage advisor or broker who understands CIS mortgages and can guide you through the process. Aries Financial is certainly an option.
