Why the figure on your payslip may produce very different mortgage results from different lenders
Your basic salary may not be your whole mortgage income
Yeovil is a working town shaped by aerospace and engineering, healthcare, retail, distribution, public services, education, the military community and skilled trades. Many local payslips therefore contain more than one number: basic salary, overtime, shift allowance, on-call payments, commission, annual bonus or income from a second role.
That additional income can make a substantial difference to the mortgage available—but lenders do not all assess it in the same way. One may use most or all of a regular allowance, another may average it, and another may apply a reduction or require a longer history.
This is why a generic online calculator can underestimate or overstate your position. A mortgage adviser in Yeovil should examine how the income is earned, how reliably it appears and which lenders’ criteria match the evidence before recommending an application.
How mortgage affordability is actually calculated
The familiar rule that a lender offers four or four-and-a-half times salary is only a rough starting point. Lenders also consider the deposit, credit history, loans, car finance, credit cards, childcare, dependants, pension deductions, student loans, property type, mortgage term and the monthly payment under their affordability model.
Some lenders may offer higher income multiples to eligible applicants, but a published maximum is not a promise. It can depend on household income, occupation, loan-to-value, credit profile and product. Two applicants earning the same amount can receive different results because their commitments and circumstances are different.
The first job is therefore not to chase the highest multiple. It is to establish which income a lender is prepared to recognise and whether the resulting mortgage remains comfortable after normal household costs.
Can overtime be used for a mortgage?
Often, yes. The lender normally wants evidence that the overtime is established, regular enough to rely upon and likely to continue. Guaranteed contractual overtime may be treated differently from voluntary hours that vary significantly each month.
A lender might use the latest figure, an average over several payslips or a percentage of the average. Some will compare the year-to-date figure with the latest P60. If recent overtime is unusually high, the lender may use a lower sustainable amount rather than annualising the best month.
Do not manufacture a short burst of overtime purely to increase the mortgage. A sudden increase can attract questions and may not be accepted. The strongest evidence is a genuine pattern supported by payslips, bank credits and, where required, employer confirmation.
Does shift allowance count as income?
A fixed, taxable shift allowance shown consistently on the payslip can often be included, although the lender’s evidence requirements still vary. A rotating allowance, night premium or unsocial-hours payment may be treated as variable income rather than guaranteed basic pay.
This distinction matters to people working in engineering, manufacturing, healthcare, care, logistics, retail and other shift-based roles around Yeovil. The label used by the employer is less important than what the payment represents, whether it is contractual and how consistently it has been received.
Prepare the employment contract if it confirms the allowance and keep enough payslips to show the pattern. If your hours or shift system recently changed, explain when and why rather than leaving the underwriter to guess.
Annual bonuses and performance-related pay
Bonuses can be accepted, but the word ‘bonus’ covers very different arrangements. A contractual annual payment, a discretionary company bonus and monthly performance pay do not carry the same certainty.
Many lenders look for a history and may average the amount over one or two years. Some use only a proportion; others can be more generous when the payment is consistent and well evidenced. If the latest bonus is lower than the previous year, the lender may use the lower figure or investigate the reason.
Provide bonus payslips, P60s and any employer documentation describing the scheme. Do not assume that a bank will multiply the best bonus you have received by an income multiple without adjustment.
Commission and monthly performance pay
Regular commission can form an important part of income in sales, recruitment, retail management and business-development roles. Lenders generally want to see a pattern rather than one exceptional month.
They may average three, six or twelve months, compare the figure with year-to-date earnings or limit the percentage used. An applicant who recently moved into a commission-heavy role may have fewer options until a track record is established, although continuity in the same industry can help with some lenders.
NHS bank shifts, on-call pay and additional hours
Healthcare income can contain basic pay, enhancements, bank shifts, overtime and on-call payments. There is no single ‘NHS mortgage’ that automatically accepts all of it. The task is to match the income evidence to a lender that understands the structure.
Regular bank work for the same trust may be assessed differently from agency work or occasional shifts for another organisation. Lenders can ask for additional payslips, P60s, bank statements or evidence of continuity. Newly qualified staff, people moving bands and applicants returning from leave may also need criteria that fit the timing of their case.
Can income from a second job be included?
Potentially. The lender will consider how long you have held the second job, the hours worked, whether the arrangement is sustainable and whether the income is evidenced. Working a modest regular weekend shift alongside a full-time role is different from relying on an extreme number of weekly hours.
Some lenders accept the full amount when the history is strong; others use a proportion or require a minimum period. The employment must be declared accurately, and tax and bank records should agree with the payslips.
New jobs, probation and apprenticeship income
Starting a new job does not automatically mean waiting six months for a mortgage. Some lenders can consider a signed contract, the first payslip or an applicant in probation. Others want a longer history, particularly when variable income is essential to affordability.
Apprentices and graduates can also obtain mortgages when the income, deposit and affordability support the application. The key questions are whether the employment is permanent or time-limited, what happens at the end of the programme and whether future pay progression can be evidenced. A hoped-for salary rise is not normally the same as current guaranteed income.
If you are planning to change employer, reduce hours or move from employment to self-employment, obtain advice before submitting the mortgage application. A material change before completion must be disclosed.
Fixed-term and agency contracts
Fixed-term employment is not automatically unacceptable. Lenders can consider the remaining contract term, previous contract history, gaps between roles, occupation and likelihood of renewal. A first short contract may be assessed more cautiously than several years of continuous work in the same field.
Agency workers should prepare contracts, payslips and a clear history of assignments. Umbrella-company deductions, holiday pay and variable weekly hours can make the headline day rate a poor guide to the income a lender will use.
An example of why lender choice matters
Consider an illustrative Yeovil applicant with a £30,000 basic salary, £6,000 regular shift allowance and £4,000 average overtime. The total received is £40,000, but that does not mean every lender will assess £40,000.
One lender might accept the full regular allowance and a strong overtime average. Another might use the allowance but only part of the overtime. A third might require more history and calculate affordability mainly from the basic salary. The resulting borrowing figures can differ by tens of thousands of pounds before commitments and product rules are considered.
This example is deliberately illustrative, not a quotation or promise. The useful lesson is that the same payslips can produce different answers, so lender research should happen before a full application and hard credit search.
Evidence to prepare before checking affordability
- Your latest three months’ payslips—more may be needed for variable income.
- Your latest P60 and, where useful, earlier P60s showing the income history.
- Bank statements showing salary credits and normal household spending.
- Your employment contract and written details of contractual allowances.
- Bonus, commission, overtime or on-call evidence covering the period requested by the lender.
- Second-job payslips, contract and employment history where relevant.
- Details of loans, cards, car finance, childcare, maintenance and dependants.
- Proof of deposit and a clear explanation of any gifted funds or recent large credits.
Avoid editing, hiding or selectively supplying documents. Inconsistencies cause delays and can lead to an application being declined. A complete file allows the adviser to research the case properly.
Questions Yeovil buyers frequently ask
Will a lender use 100% of my overtime?
Some may when it is regular, sustainable and sufficiently evidenced; others use an average or a proportion. The answer depends on the lender and the pattern shown in your documents.
How many payslips will I need?
Three months is common for employed income, but variable pay can require a longer period or additional P60 evidence. Obtain the lender-specific requirement before applying.
What if my latest overtime is lower?
The lender may use the lower recent figure or a cautious average. Explain one-off reasons accurately, but do not assume older, higher earnings will automatically be used.
Can I include an annual bonus that is discretionary?
Possibly. A lender may accept some or all of a well-established discretionary bonus, but history and consistency are important. Policies differ materially.
Can I get a mortgage while on probation?
Possibly. Some lenders accept probation or a new employment contract, while others want payslips or a longer record. The role and previous employment history also matter.
Should I apply to my own bank first?
Not necessarily. Your bank only applies its own criteria. Researching the wider market first can avoid an unsuitable application and unnecessary credit search.
