Contractor mortgages: getting approved on a day rate
How lenders annualise a contract day rate, how much contracting history you need, how gaps between contracts are treated, and what changes if you work through an umbrella or inside IR35.
Written and reviewed by the MortgageMatch editorial team. How we research and review our guides.
Some lenders will assess a day rate contractor on the contract itself rather than on company accounts. A common approach is to annualise the day rate by multiplying it by five days and then by somewhere between 46 and 48 weeks, and to lend an income multiple of that figure. Most want around 6 to 12 months of contracting history and a current contract with a reasonable amount of time left to run. It is a niche policy, not a universal one.
Why contractors get assessed differently
If you contract through your own limited company, the default self-employed treatment looks at salary plus dividends from your accounts. Many contractors pay themselves a small salary and modest dividends, leaving the rest in the company or in a pension. On paper that makes a well-paid contractor look like a low earner.
Contractor lending exists to fix that mismatch. Instead of reading the accounts, the underwriter reads the contract, works out an annual equivalent, and treats you much like an employee on that salary. It is the same product range as anyone else in many cases, just a different way of evidencing income.
How day rate annualisation works
The formula most commonly used is day rate multiplied by five, multiplied by the number of working weeks the lender assumes. Lenders that use 46 weeks are building in six weeks of unpaid time off. Those using 48 are more generous. A few will use 47.
Take a contractor on 450 a day. Five days gives 2,250 a week. At 46 weeks that is 103,500. At 48 weeks it is 108,000. Using an illustrative income multiple of 4.5 times, purely to show the mechanism, the 46 week figure supports around 465,750 and the 48 week figure around 486,000.
Now compare that to the accounts route for the same person. Suppose they took a 12,570 salary and 45,000 of dividends last year. That is 57,570 of income, and at the same illustrative 4.5 times multiple it supports around 259,065. The difference between the two approaches on identical earnings is roughly 200,000 of borrowing. This is why the choice of lender is the whole game for contractors.
If you work a four day week, say so up front. Lenders will normally annualise on the days you actually work rather than assuming five.
How much history you need
Expect most contractor lenders to want somewhere between 6 and 12 months of continuous contracting, though a minority will consider less where you have moved into contracting in the same field you were employed in. If you were a permanent software engineer on 70,000 and you are now contracting at 500 a day doing the same work, that continuity helps a great deal.
Lenders also look at the current contract. Many want at least three to six months left to run at the point of application, or a documented history of renewals with the same client. A contract that expires next month with no renewal in sight is a weak position, so time your application around your renewal cycle where you can.
Some lenders will also want to see that your day rate has been stable or rising. A rate that has fallen sharply between contracts invites the same questions a falling profit does for a sole trader.
Gaps between contracts
Gaps are normal in contracting and lenders know it. What they care about is the pattern. A few weeks between engagements, once or twice a year, is usually fine and is precisely why the annualisation uses 46 to 48 weeks rather than 52.
Longer gaps need explaining. A three month break because you took time out, moved sector, or waited for a project to start is explainable in a short covering note. Several long gaps in a 12 month period is harder, and some lenders will average your actual earnings over the period instead of annualising the current rate, which usually produces a lower figure.
Keep your own record. A simple schedule listing each contract, the client, the dates and the day rate makes an underwriter's job easy and makes you look organised.
Umbrella, own limited company, and inside IR35
How you are paid changes which lending route is open to you.
- Own limited company, outside IR35. The classic contractor case. You can normally choose between contract based assessment and accounts based assessment, whichever gives the better result, though not every lender offers both.
- Umbrella company. You are technically employed by the umbrella, which issues payslips and deducts tax. Some lenders treat umbrella contractors as employed and will assess payslips, but the gross figure on an umbrella payslip is reduced by the umbrella's fees and employer costs, so the net position often looks worse than the headline day rate. Other lenders will still annualise the day rate from your contract, which usually gives a better answer.
- Inside IR35 through a client payroll or umbrella. Similar territory. You will have payslips, and some lenders will use them like an employee's. Others will use the contract. It is worth getting both assessments quoted.
- CIS subcontractors in construction. Often treated as self-employed, though some lenders have specific CIS policies that work from monthly payment statements rather than full accounts.
None of this is fixed and lenders change their contractor policies fairly often, so treat the above as the shape of the market rather than a rulebook.
Documents you will need
- Your current signed contract, showing the day rate, start and end dates and the parties
- Previous contracts covering your contracting history, ideally back at least 12 months
- Any signed extension or renewal, or written confirmation one is coming
- Three to six months of personal bank statements
- Business bank statements if you contract through your own company
- Your CV, which lenders often ask for to evidence continuity of profession
- Company accounts and SA302s, which may still be requested even on contract based assessment
- Proof of deposit, identification and address documents
Make sure the contract names you or your company as the contracting party and states the rate clearly. Contracts that show a rate range, or that leave the rate to a separate schedule you do not have, cause delays.
Where contractor applications fall down
The most common failure is applying to a lender with no contractor policy at all. That lender reads your accounts, sees 57,570, and offers half what you expected. Nothing is wrong with the application, it is simply in the wrong place.
The second is timing. Applying with six weeks left on a contract and no renewal, or immediately after switching from permanent work with no track record, both narrow your options.
The third is the day rate not matching the bank statements. If your contract says 450 a day but your company account shows income consistent with 350, expect the file to stall while the underwriter reconciles the two.
Because contractor policy varies so widely and changes often, this is one area where a broker who places contractor cases regularly is worth finding. The MortgageMatch directory lets you search FCA-authorised brokers so you can start with someone who knows which lenders will read your contract rather than your accounts.
Frequently asked questions
- How do lenders work out income from a day rate?
- A common approach is to multiply the day rate by five days a week, then by 46 to 48 weeks a year, building in unpaid time between contracts. A 450 day rate annualises to 103,500 at 46 weeks or 108,000 at 48. The lender then applies an income multiple to that figure much as it would to a salary.
- How long do I need to have been contracting to get a mortgage?
- Most lenders that assess contractors on day rate want around 6 to 12 months of contracting history plus a current contract with time left to run. Some will consider less if you moved into contracting from a permanent role in the same field, since that shows continuity of profession. Criteria vary considerably between lenders.
- Do gaps between contracts stop me getting a mortgage?
- Short gaps of a few weeks are expected and are the reason lenders annualise on 46 to 48 weeks rather than 52. Longer or repeated gaps prompt questions and some lenders will use your actual earnings over the period instead of the current day rate. A written explanation and a clear schedule of past contracts both help.
- Can umbrella company contractors get a contractor mortgage?
- Often yes. Some lenders treat umbrella contractors as employed and assess the payslips, though umbrella fees and employer costs reduce the figure shown. Others will still annualise the day rate from the underlying contract, which usually produces a higher income. It is worth having both routes assessed before choosing a lender.
- Does being inside IR35 affect my mortgage application?
- It changes how you are paid and therefore what evidence exists. Inside IR35 work is usually paid through a client payroll or umbrella, so you will have payslips that some lenders assess like an employee's. Other lenders will still work from the contract and day rate. Being inside IR35 is not itself a barrier to borrowing.
- Will a lender want my company accounts as well as my contract?
- Sometimes. Even on contract based assessment, many lenders ask for company accounts, SA302s or business bank statements as supporting evidence and to sanity check that the day rate matches what has actually been received. Have them available. If the accounts contradict the contract, the application will stall until it is explained.
