Mortgage for Self-Employed Construction Worker

What challenges do self-employed construction workers face when applying for a mortgage?

Self-employed individuals often face a primary hurdle when applying for mortgages – proving their income. Unlike PAYE (Pay As You Earn) employees, who can simply provide payslips, self-employed workers must demonstrate a consistent earning history through financial documents like accounts and tax returns.

I wouldn’t say it’s harder, just more paperwork. It’s a bit more long-winded, and as a result of having to provide that evidence, it normally makes it difficult from an affordability perspective. That’s what we tend to find is the main difference between employed and self-employed individuals – income and affordability.

What documents are required for a mortgage if I’m self-employed in construction?

For self-employed individuals, the primary documents required are typically your SA302s (tax calculations) along with your tax year overview documents. If you operate as a limited company, you will also need to provide business and limited company accounts. This is because lenders require evidence of stable and consistent income.

In the construction industry, there’s a unique approach for individuals that bridges the gap between employment and self-employment. If you’re part of the Construction Industry Scheme (CIS), you can often provide payslips, and some lenders will assess you more like an employed individual than a self-employed one. This specific nuance within the industry means that many of the answers I provide today will address both scenarios.

How many years of accounts or tax returns do I need? Can I get a mortgage if I’ve been self-employed for less than a year?

For most lenders, two or three years of self-employment history are typically required, though some may consider one year. If you’ve been self-employed for less than a year, obtaining a mortgage is generally not possible. However, if you’re part of the Construction Industry Scheme (CIS), you may be able to secure a mortgage with just three months’ worth of payslips, provided you have a proven track record in the industry.

If you’ve been working as a self-employed chippie for two years and have been part of the Construction Industry Scheme (CIS) for the past three months, for example, you could be eligible for a mortgage. This is provided that your payslips show tax deductions through the CIS, as this effectively mirrors an employed status for lenders.

Do I need to be registered as a sole trader or a limited company? Is it easier to get a mortgage as a limited company director or sole trader?

Lenders are generally flexible whether you operate as a sole trader or a limited company, though the assessment process differs slightly. Sole traders are evaluated based on their profit, while company directors’ affordability is calculated from either the company’s net profit or the sum of their salary and dividends.

If you’re a self-employed construction worker operating as a sole trader or through a limited company under the Construction Industry Scheme (CIS), we can assist you in securing a mortgage, provided you have three months’ worth of payslips.

How do lenders calculate income for self-employed construction workers?

As I mentioned, for sole traders, lenders consider your net profit. For company directors, they have two options – either the limited company’s net profit, or the combined dividends and salary. Those are the three main approaches. However, in this case, we’re introducing a fourth option, which is the CIS scheme.

Lenders typically assess a borrower’s annual income by averaging their last three months’ payslips. They then multiply this average by 12, and subsequently by roughly 46 or 48 weeks (depending on the lender) to account for holiday time.

Hopefully, that clarifies how they’ll annualise your income if you choose the CIS route. It’s quite complex at the CIS level, with various factors such as being a limited company, sole trader or CIS, and profits, salary, or dividends all playing a role.

Can I use retained profits or dividends as income?

Dividends are generally accepted. Retained profits can sometimes be considered, but only by a limited number of lenders – fewer than you can count on one hand. If you’re considering this, I highly recommend consulting a broker specialising in self-employed individuals in the construction industry.

It’s not uncommon to find that you could borrow more with a lender that doesn’t factor in retained profits but offers a higher multiple, even if you’re trying to use retained profits to boost your affordability. Expert advice is therefore crucial to avoid being pigeonholed when exploring such options.

Will irregular income or seasonal work affect my mortgage application?

Lenders typically prefer steady earnings. If your income fluctuates, they are likely to use an average. Therefore, consistent income is beneficial. However, in the construction industry, particularly in sectors like plumbing, earnings can be seasonal, with higher income in winter than in summer. In such cases, averaging the latest three months using the Construction Industry Scheme (CIS) approach might result in a lower assessable income during summer months compared to winter months.

Given the various ways to structure this income, it’s advisable to consult an expert. They can analyse all options and determine the most suitable one for you, considering both high and low seasons.

How much can I borrow as a self-employed construction worker?

Mortgage lenders usually let you borrow about four to five times your annual income. That goes for everyone, whether you’re employed or self-employed.

The exact amount depends on who you go with. It’s going to depend on your credit history, and it’s also going to depend on what the situation is with your financial commitments in the background. Every lender will offer you a different amount. If that gets you where you need to be, then that’s great. If it doesn’t, then effectively, you need to look at how your income needs to change over the coming years to achieve your affordability goals.

What if my most recent year’s income is lower than the previous year’s?

That can be tricky, but lenders may take the lowest income year, especially if your earnings are trending downwards, rather than averaging them out. While this isn’t ideal, fluctuating self-employed income is common, and you work with the figures you have.

For instance, many people have not submitted their accounts for the last financial year. This means you can review the administrative aspects of your business and discuss with your accountant what steps can be taken to get back on an upward trend. However, if your business is on a downward trend and you’ve submitted your most recent accounts, lenders will likely focus on that most recent year.

Which mortgage lenders accept self-employed construction workers, and are there specialist lenders or brokers for self-employed mortgages?

Most lenders are willing to offer a mortgage to self-employed individuals in the construction industry, whether they operate as a sole trader or a limited company, provided they are within the appropriate tax wrapper.

For those assessed on a CIS (Construction Industry Scheme) basis, where the latest three months’ payslips are used, you would be considered closer to employed status. A limited number of lenders and brokers specialise in this area.

A broader approach may grant access to all available rates. However, if the CIS route is more suitable, you might have a more limited selection of lenders.

Have you got anything else you’d like to add?

It’s worth noting that we’ve been discussing recent significant changes some lenders are making regarding the Construction Industry Scheme, which is highly relevant to these questions.

As a broker who has witnessed many changes over the years, I want to emphasise that it’s September 2025 at the time of recording this podcast, and this type of CIS-based arrangement may not always be available. Lenders are becoming increasingly aware of this, and it’s becoming more restrictive to bridge the gap between tax and mortgage borrowing perspectives.

If you’re considering this, I’d suggest prioritising it sooner rather than later. In my opinion, these opportunities that seem too good to be true don’t last forever. That’s my crystal ball prediction from Paul Holland at Henchurch Lane!
