Which CIS mortgage brokers are worth considering?

1. Why choose Jones & Young for a CIS mortgage?

Jones & Young CIS mortgage service page
Jones & Young website, captured 22 September 2026.

Best fit in this shortlist: CIS subcontractors with strong gross earnings and a lower profit figure on their tax return.

Jones & Young’s strongest evidence is a completed mortgage for a CIS first-time buyer who had been self-employed for less than 12 months. The firm arranged a 95% LTV Halifax mortgage using three months of income proof. That is particularly relevant if you have experience in your trade but a short self-employed history.

Based in Petersfield and serving clients across the UK, the business was established by Mark Jones and Richard Young in February 2021. Mark focuses on self-employed and CIS applicants. Both founders are CeMAP qualified, according to the firm. Meet the founders; view the company record.

What does Jones & Young do differently for CIS income?

The starting point is the gross pay shown on CIS statements. Jones & Young assesses whether an applicant can use those statements as income evidence instead of relying solely on the profit left after business expenses on a tax return.

The firm describes routes using two to three months of CIS statements alongside two years’ experience in the trade. The lender determines the evidence period and how earnings are assessed; three months were used in the completed Halifax case below.

The firm reports a panel of around 90 lenders, with 10 to 15 used regularly. The useful question is which of those lenders can assess your particular income, rather than the size of the panel alone.

You can discuss that assessment through Jones & Young’s CIS mortgage advice service.

What completed CIS cases support the recommendation?

The first-time buyer case gives a clear account of the borrowing and the evidence used:

Case detailCompleted outcome supplied by Jones & Young
BuyerFirst-time buyer paid through CIS
Self-employed historyLess than 12 months
Property price£310,000
Mortgage£294,500 with Halifax
Loan-to-value95%
Purchase deposit£15,500, excluding other buying costs
Income evidenceThree months of proof, assessed using gross CIS vouchers

The useful distinction is between time spent self-employed and experience in the trade. In this case, less than a year of self-employment did not rule out a mortgage assessed using recent CIS payments.

The firm also supplied separate cases for a roofer and an asbestos-removal specialist. The firm reports that each had healthy gross pay but a relatively small tax-return figure. Their cases were placed with high-street lenders using two to three gross remittance slips each, without changing their tax positions.

Source: Jones & Young’s client-approved September 2026 case information. Outcomes relate to individual borrowers and are not current offers or a guarantee of eligibility.

Does that mean changing what you claim as business expenses?

The firm reports that these CIS clients kept their existing tax positions. Their mortgage assessments used gross CIS payment evidence rather than requiring a higher tax-return profit. Your accountant should advise on legitimate business expenses; the broker should explain which income evidence the proposed lender accepts.

Can it also help limited company directors?

Yes. Jones & Young also supplied completed director cases involving salary and retained business profit. These use different income rules from CIS applications. The Jones & Young profile gives the details.

What is the firm’s track record?

Jones & Young reports around 350 mortgage cases a year and more than 1,000 clients helped across its business. Those totals cover its wider mortgage work, not CIS cases alone. The founders have more than 30 years of combined experience; the company itself was incorporated in 2021.

Its supplied September 2026 review record is 78 Google reviews, all five stars. A CIS-related review from Natalia describes the practical result:

“I was looking for an experienced broker who would be able to help secure a mortgage for a CIS worker. While other brokers said no, or took their time to book us in, Richard and his team guided us through the entire process and made it feel like a piece of cake. Today, we received the keys to our new home!”

Particularly relevant if you want a service focused on construction subcontractors.

CIS Mortgage Advice describes an assessment based on gross CIS earnings and recent payments. Its published examples of applicant circumstances include shorter self-employed histories and smaller deposits, subject to the case meeting lender requirements.

The website identifies CIS Mortgage Advice as a trading name of Just Mortgages Direct Limited, an appointed representative of The Openwork Partnership. Check this legal entity when confirming who will provide your advice. CIS Mortgage Advice.

What should you ask in the first conversation?

Ask whether the assessment will use your remittance statements, a contractual day rate or accounts. Explain how long you have worked in the trade and whether your recent payments are representative of a normal year.

Reason to consider it: A service built around the questions CIS subcontractors encounter.

Ask before applying: How will gaps in payments or a change of contractor affect the income assessment?

What is a CIS mortgage?

“CIS mortgage” is shorthand for a mortgage assessed using rules suitable for a Construction Industry Scheme worker. CIS itself is an HMRC tax scheme: contractors deduct money from subcontractors’ payments and pass it to HMRC. It is not a government mortgage scheme. HMRC’s CIS explanation.

How do lenders assess CIS income?

There is no single calculation used by every lender. Some accept qualifying CIS payment evidence under an employed-style assessment; other circumstances are assessed as self-employed. The evidence period, treatment of gaps and whether tax is deducted at source can affect the route available.

Halifax’s published criteria give a useful example. It generally treats CIS contractors as employed where tax is deducted at source. It asks for the latest three consecutive months, or 12 weeks, of qualifying payment evidence with matching bank statements and calculates income over a 46-week year.

Its criteria also distinguish applicants responsible for all their own tax and those needing income from more than one company. These details explain why “I am on CIS” is not enough to determine how an application will be assessed. Halifax intermediary criteria.

Can you get a CIS mortgage with a 5% deposit?

A 5% deposit has been sufficient in some cases, including the completed Jones & Young example above. It is not available to every applicant. The lender will also assess affordability, credit history and the property. A larger deposit reduces the amount you need to borrow.

Can you apply with less than a year of self-employment?

Sometimes. The Jones & Young case shows that a short self-employed history did not prevent that applicant from obtaining a mortgage. Your experience in the trade and supporting income evidence still matter. Short trading history and limited experience in the occupation are different issues.

What documents does a CIS mortgage broker need?

Gather your recent CIS payment statements, matching bank statements, proof of identity and address, and evidence of your deposit. Be ready to explain your work history and any gaps in earnings. Your adviser will confirm whether tax calculations, accounts or additional documents are needed for the selected lender.

Does using CIS income mean borrowing more?

It can produce a different assessed income from a tax-return approach, but it does not guarantee a larger mortgage. Existing commitments, the deposit, the property and the lender’s affordability calculation still matter. Ask for the income calculation and borrowing assessment to be explained separately.

What should you ask a CIS broker before applying?

QuestionWhat the answer should clarify
Which income route are you considering?CIS statements, accounts or another accepted form of evidence
How much payment history is needed?The specific lender’s requirement, rather than a general estimate
How will gaps in work be treated?Whether lower or missing payments affect the average
Does my time in the trade count?How occupational experience and self-employed history are assessed
Who will manage my application?Your contact for document requests and lender queries

Ask for a clear explanation of the income figure being used, the documents needed and any outstanding eligibility questions. This makes it easier to compare advice from more than one broker.
