Contractor Mortgages: Getting Approved on a Day Rate

1 Step 1

A contractor mortgage is a home loan assessed on your day rate or annual contract value rather than on company accounts or a permanent salary. Specialist lenders take your daily rate, annualise it, and lend against that figure, which usually lets a contractor borrow far more than salary-and-dividend accounts would allow.

Key takeaways

Lenders annualise your day rate as day rate multiplied by 5, multiplied by 46 to 48 weeks. Most use 46 weeks.
Standard borrowing is 4.5 times annualised income, rising to 5 or 5.5 times for higher earners with strong credit.
You do not need two years of accounts. Many lenders accept 12 months of contracting, and some accept from 3 to 6 months with prior industry experience.
Being inside IR35 does not block a mortgage. Umbrella and PAYE-contractor income can still be annualised by the right lender.
Deposits usually start at 5 to 10 percent, with better rates from 15 percent upward.
Using the wrong lender is the single biggest reason contractors under-borrow or get declined.

Can contractors get a mortgage?

Yes. Contractors can get a residential mortgage, and often borrow more than they expect, provided the application goes to a lender that underwrites contract income properly. The problem is never the contract itself. It is that most high-street branch staff assess a contractor as if they were self-employed, averaging one or two years of net profit or salary plus dividends, which strips out the real earning power of a day rate.

The fix is a lender that reads your signed contract and annualises the day rate directly. Halifax, Clydesdale Bank, Virgin Money, Santander, Kensington and Skipton all run contractor-specific policies of this kind. Whole-of-market advice matters here because the criteria differ lender to lender, and the right placement can be the difference between a mortgage offer and a decline.

How do lenders work out your income from a day rate?

Lenders convert your day rate into an annual figure using a fixed formula: day rate multiplied by 5 working days, multiplied by the number of working weeks the lender assumes in a year. Most lenders use 46 weeks, which builds in a buffer for holidays and gaps between contracts. Some use 48 weeks, which produces a higher assessed income.

Take a contractor on £450 per day. The table below shows how the annualised figure changes with the lender’s week assumption.

Annualisation basis	Weeks used	Assessed annual income (£450/day)
Conservative	46	£103,500
Standard	48	£108,000
Salary plus dividends (accounts)	n/a	Often £40,000 to £55,000

That final row is the crux. A contractor who leaves most profit in the company, or draws a small salary and modest dividends, might show £45,000 on their tax return while genuinely earning six figures. The day-rate route assesses what you actually earn, not what you draw.

How much can you borrow as a contractor?

Once your day rate is annualised, lenders apply an income multiple. The standard is 4.5 times income. Higher earners, or applicants with strong credit and a larger deposit, can reach 5 times, and a handful of lenders go to 5.5 times. Using the £450 per day example annualised at 46 weeks (£103,500):

At 4.5 times: around £465,750
At 5 times: around £517,500
At 5.5 times: around £569,250

Compare that with salary-and-dividend accounts showing £45,000, which at 4.5 times gives roughly £202,500. Same person, same real income, more than double the borrowing simply through correct lender placement. This is why the lender you apply to matters more than almost anything else in a contractor case.

Does IR35 affect your mortgage?

IR35 changes how you are paid, which changes how a lender reads your income, but it does not stop you getting a mortgage. Being inside IR35 means your engagement is treated like employment for tax, so you are usually paid through an umbrella company under PAYE. Being outside IR35 means you invoice through your own limited company. Both routes are mortgageable with the right lender.

Your IR35 position	How you are typically paid	How lenders assess income
Outside IR35	Own limited company	Day rate annualised, or salary plus dividends
Inside IR35	Umbrella company (PAYE)	Gross day rate or umbrella payslips annualised by specialist lenders
Fixed-term or agency PAYE	Employer or agency PAYE	Often treated close to employed status

Inside-IR35 contractors often assume they are stuck with only their net umbrella pay. Specialist lenders instead gross up the day rate, so you are assessed on your full earning power. One point on the horizon: from April 2026 the small company thresholds that decide who assesses IR35 status rose to £15m turnover, which will let more contractors self-assess their own status again as those changes work through. Your status still matters more than any single threshold, so get it confirmed before you apply.

How much deposit do you need as a contractor?

Deposit expectations for contractors are the same as for any residential borrower. A minimum of 5 percent is possible with the right lender, though most contractor cases sit comfortably at 10 to 15 percent, and the sharpest rates open up at 25 percent and above. A larger deposit also reduces underwriting friction: at lower loan-to-value the lender is taking less risk, so contract-history and income tests are applied more generously.

First-time buyer contractors are well catered for. The day-rate assessment applies whether you are buying your first home or your fifth, and it pairs naturally with any first-time buyer scheme you qualify for. If you are buying your first property, our self-employed first-time buyer guide covers the overlap.

How much contract history do lenders want?

Most lenders want to see 12 to 24 months of continuous contracting, but this is far more flexible than contractors expect. Several lenders accept from 3 to 6 months in your current contract provided you have a track record in the same field, and short gaps of 4 to 6 weeks between contracts are treated as normal rather than a red flag.

New contractors have routes too. If you have recently moved from employment into contracting in the same profession, lenders such as Halifax can consider you with as little as a few months of contract evidence, because your industry experience de-risks the switch. Lenders also want to see time left on your current contract, typically 4 weeks or more, or a history of renewals. Between-contract gaps do not sink an application when the overall pattern shows consistent work.

How does underwriting differ by contractor type?

Lenders do not treat all contractors the same. The evidence you provide and the criteria applied depend on how you contract and how you are paid.

Contractor type	Typical evidence	Underwriting note
IT and day-rate consultants	Signed contract, 3 to 12 months history	With the right lender there is often no minimum income, only the day rate
Locum and medical (NHS)	Timesheets, booking records, contracts	Professional status can unlock higher multiples
CIS construction subcontractors	CIS payslips, usually 3 to 6 months	Assessed on gross pay, before the 20 percent CIS deduction
Umbrella and inside IR35	Umbrella payslips, contract	Specialist lenders gross up the day rate rather than using net pay

The CIS point is worth stressing. Construction subcontractors are taxed at source under the Construction Industry Scheme, and a lender that assesses your post-deduction figure will understate your income. A contractor-aware lender uses the gross figure, and CIS subcontractors can borrow up to 5 times income on that basis.

A worked contractor case study

An IT contractor came to us on £500 per day, working outside IR35 through a limited company, with 14 months of contracting behind him and five years as a permanent developer before that. He wanted to borrow £420,000 with a 10 percent deposit. His accountant had structured a low salary plus retained profit, so his tax return showed around £52,000, and two high-street branches had capped him near £235,000.

We annualised his day rate at £500 multiplied by 5, multiplied by 46 weeks, giving £115,000 assessed income. Placed with a lender offering 5 times income to contractors, that supported borrowing above £575,000, comfortably covering the £420,000 he needed at 85 percent loan-to-value. The case did not need a bigger deposit or a higher rate. It needed the right lender reading the contract correctly.

What is the Knox contractor mortgage process?

Knox runs contractor cases on a systemised process so nothing stalls on missing paperwork. The typical timeline is 4 to 6 weeks from application to offer, faster when documents are ready up front.

Week 1: Discovery call, day-rate assessment, agreement in principle with a contractor-friendly lender.
Weeks 2 to 3: Full application submitted with contract and income evidence, valuation instructed.
Weeks 4 to 6: Underwriting, mortgage offer issued, on to conveyancing.

Have these ready to move quickly. Our full mortgage document checklist covers the detail.

Your current signed contract showing day rate, start and end dates
Evidence of contract history or CV showing continuity in your field
Three to six months of personal and business bank statements
Umbrella or CIS payslips where relevant, or SA302s and company accounts for limited company contractors
Proof of deposit and standard ID

Can you remortgage as a contractor?

Yes. Contractors can remortgage or take a product transfer using the same day-rate assessment as a purchase. This matters because a fixed rate taken while you were employed, or arranged through a lender that averaged your accounts, may now be understating your income. Remortgaging to a contractor-aware lender can release equity, lower your rate, or raise capital for a deposit on a buy-to-let if you are building a portfolio.

Time the switch around your product end date to avoid early repayment charges, and start roughly 4 to 6 months ahead so the new deal is ready when the old one ends. If your day rate has risen since you last borrowed, your borrowing capacity has likely risen with it.

Should contractors consider income protection?

Yes, more so than most employees. Contractors have no sick pay, no employer benefits and no notice period cushioning a gap between contracts. Income protection replaces a percentage of your earnings if illness or injury stops you working, which directly protects your ability to keep paying the mortgage. It is the cover most contractors overlook and most need.

We build protection into the advice rather than bolting it on afterwards, so the policy reflects your real day-rate income and your contracting pattern. Read more on income protection, or raise it on your discovery call.

Frequently asked questions

Can contractors get a mortgage on a day rate alone?

Yes. Contractor-friendly lenders assess your mortgage on your day rate annualised as day rate multiplied by 5, multiplied by 46 to 48 weeks. You do not need years of company accounts. A current signed contract and evidence of continuity in your field is usually enough.

How much can I borrow as a contractor?

Typically 4.5 times your annualised income, rising to 5 or 5.5 times for higher earners with strong credit and a good deposit. On a £450 day rate annualised at 46 weeks (£103,500), that is roughly £465,750 at 4.5 times and £517,500 at 5 times.

Does being inside IR35 stop me getting a mortgage?

No. Inside-IR35 income, paid through an umbrella company or PAYE, is fully mortgageable. Specialist lenders gross up your day rate rather than using only your net umbrella pay, so you are assessed on your true earning power.

How much deposit do I need as a contractor?

From 5 percent with the right lender, though most contractor cases sit at 10 to 15 percent. The sharpest rates open up from 25 percent deposit. A larger deposit also eases the contract-history and income checks because the lender is taking less risk.

Can I get a mortgage as a new contractor with under 12 months of history?

Yes, in many cases. Several lenders accept from 3 to 6 months of contracting if you have prior experience in the same profession. Halifax and specialist lenders such as Kensington are among the more flexible on short contract history.

Do gaps between contracts affect my mortgage?

Short gaps of 4 to 6 weeks are treated as normal and do not sink an application. Lenders look at the overall pattern of continuous work, not isolated breaks. Longer gaps are best explained up front so the lender can see they were planned or one-off.

How are CIS subcontractors assessed for a mortgage?

CIS subcontractors are assessed on gross pay, before the 20 percent Construction Industry Scheme deduction, using 3 to 6 months of CIS payslips. On that basis you can borrow up to 5 times income. Using a lender that reads the net figure would understate what you earn.

Should I use a specialist broker for a contractor mortgage?

Yes. Criteria differ sharply between lenders, and the wrong placement can halve your borrowing or trigger a decline. A whole-of-market broker matches your contract type, IR35 status and history to the lender that reads them most favourably. See our day-rate contractor mortgage page for how we place these cases.
