Bonuses, commission and overtime can potentially be used to support a mortgage application.

But lenders do not always treat variable income in the same way as fixed salary.

A borrower may earn a substantial proportion of their annual income through:

discretionary bonus;

contractual bonus;

sales commission;

regular overtime;

shift allowances;

performance-related pay;

vested equity awards;

or other variable remuneration.

The challenge is not necessarily that the income is variable.

It is whether the lender believes it is sufficiently consistent, sustainable and evidenced to rely upon for a long-term mortgage.

The useful question is therefore not simply:

“Will a lender use my bonus or overtime?”

It is:

“How much of that income will the lender recognise, and what evidence will it require to treat it as sustainable?”

Can bonuses be used for a mortgage?

Potentially.

Bonus income is commonly considered by mortgage lenders, particularly where it forms a regular part of the borrower’s remuneration.

The lender may look at:

how long bonuses have been received;

how frequently they are paid;

whether they are contractual or discretionary;

how much they vary;

employer;

current basic salary;

and whether there is evidence that the bonus structure is expected to continue.

Different lenders can reach very different borrowing figures from the same bonus history.

Do lenders use 100% of bonus income?

Sometimes, but not necessarily.

A lender may:

use all of an established bonus;

use only a proportion;

average several years;

use the lower of recent figures;

or exclude it entirely if the history is too short or inconsistent.

The exact approach varies by lender.

For a borrower whose bonus represents a large proportion of total compensation, this can materially change mortgage capacity.

How many years of bonus history do lenders want?

There is no universal rule.

Some lenders may be comfortable with a relatively short history where the bonus is clearly established and the wider employment profile is strong.

Others may want evidence over a longer period.

The lender may compare:

most recent bonus;

previous bonuses;

basic salary;

and total remuneration.

A consistent three-year history may provide more confidence than one unusually strong year.

But the quality of the evidence matters as much as the number of years.

What if the latest bonus is much higher?

That can require explanation.

Suppose a borrower received:

£50,000 two years ago;

£55,000 last year;

and £100,000 this year.

A lender may not automatically use the full £100,000.

It may want to understand whether the increase reflects:

a promotion;

higher employer performance;

a change in bonus structure;

or an exceptional one-off payment.

A higher recent figure can support the case where it is credible.

It should not simply be assumed to represent the new recurring level.

What if the latest bonus is lower?

Again, context matters.

A lower bonus may reflect:

weaker company performance;

temporary market conditions;

parental leave;

a change in role;

or a one-off event.

Some lenders may use an average.

Others may place greater weight on the latest figure.

The relevant question is whether the reduction appears temporary or indicates a lower ongoing level of remuneration.

Does a contractual bonus count differently?

Potentially.

A contractual or guaranteed bonus may be easier for a lender to rely upon than a wholly discretionary one.

The lender may want evidence through:

employment contract;

remuneration letter;

payslips;

or employer documentation.

But even a contractual bonus may have conditions attached to it.

The lender still needs to understand the actual structure.

Can annual bonuses be used if you have only just changed jobs?

Potentially.

A borrower may move employers while remaining in the same profession and compensation structure.

The lender might consider:

historic bonus earnings;

new employment contract;

current salary;

employer;

role;

and whether the new remuneration model is comparable.

One lender may insist on bonus history with the current employer.

Another may take professional continuity into account.

Can bonuses from a new promotion be used?

Potentially.

A senior executive who has just been promoted may now have a materially larger bonus opportunity.

The lender may consider:

new base salary;

contractual bonus terms;

historic earnings;

employer;

and career history.

The key distinction is between confirmed remuneration and expected remuneration.

A lender is more likely to rely on income that can be evidenced than an optimistic projection of future bonuses.

Can commission be used for a mortgage?

Potentially.

Commission is common in:

sales;

recruitment;

financial services;

technology;

property;

and other performance-driven roles.

The lender may consider:

history of commission earned;

consistency;

frequency of payments;

basic salary;

and how dependent total remuneration is on commission.

The greater the proportion of income that is variable, the more important the track record can become.

Do lenders average commission income?

Often, potentially.

A lender may average commission over a period to reduce the effect of unusually strong or weak months.

Another lender may use a percentage of the most recent annual figure.

Some may treat monthly recurring commission more favourably than a large annual discretionary payment.

The exact methodology matters.

What if commission changes every month?

That is not necessarily a problem.

Many commission-based roles naturally produce uneven monthly payments.

The lender may look at a longer period to establish a sustainable average.

For example, it may be more useful to assess twelve or twenty-four months of earnings than one unusually strong quarter.

Variability alone does not mean the income is unreliable.

Can commission make up most of your income?

Potentially.

A borrower might earn:

£50,000 basic salary;

plus £120,000 commission.

That can still form a strong mortgage case.

But lender choice becomes important.

One lender may recognise a large proportion of the commission.

Another may use far less.

The same borrower can therefore receive very different maximum loan amounts.

Can overtime be used for a mortgage?

Potentially.

Regular overtime may be accepted where it is:

established;

evidenced;

and expected to continue.

This can be particularly relevant for:

doctors;

nurses;

emergency-service workers;

engineers;

transport workers;

and other professions where overtime or additional shifts are common.

The lender may assess the history and frequency of the overtime.

Do lenders use all overtime income?

Not necessarily.

Some may use all of a consistent overtime history.

Others may use a proportion or average.

The treatment can depend on whether the overtime is:

guaranteed;

regular;

seasonal;

voluntary;

or exceptional.

A one-off period of unusually high overtime may be assessed more cautiously.

What if overtime is essential to your total income?

Then lender selection can materially affect affordability.

A borrower may have:

£60,000 basic salary

plus

£30,000 regular overtime.

If one lender uses only the salary, it assesses £60,000.

If another recognises most of the overtime, it may assess closer to £90,000.

That difference can be substantial.

The key is whether the overtime genuinely forms part of the normal remuneration pattern.

Can shift allowances be included?

Potentially.

Shift allowances, location allowances and similar regular payments may be considered where they are:

consistent;

evidenced;

and expected to continue.

The lender may distinguish between:

permanent contractual allowances;

and temporary or role-specific payments.

The stability of the allowance matters.

What about on-call income?

Potentially.

Doctors and other professionals may receive recurring on-call or additional-duty payments.

A lender may want to understand:

how long the income has been received;

whether it is part of the normal role;

frequency;

and sustainability.

A regular on-call component may be treated differently from occasional ad hoc payments.

Can locum income be combined with salary?

Potentially.

A doctor might receive:

salaried NHS income;

overtime;

on-call payments;

and locum income.

The lender may be prepared to assess several sources together.

But the locum element may be treated as self-employed or secondary income depending on the arrangement.

The lender needs to understand how it is earned.

Can bonuses and commission be combined?

Potentially.

A borrower may receive:

basic salary;

quarterly commission;

annual bonus;

and vested stock.

The lender may assess each component separately before combining the recognised amounts.

This is why simply adding all annual remuneration together can be misleading.

The relevant income is not necessarily what the borrower earned. It is what the lender is prepared to rely upon.

What if there are several forms of variable income?

This is common among high earners.

A senior executive could receive:

salary;

cash bonus;

performance bonus;

share awards;

and investment income.

A salesperson may receive:

basic salary;

monthly commission;

quarterly incentives;

and annual bonus.

The lender should be able to distinguish:

recurring income;

truly discretionary income;

and one-off payments.

The clearer the structure, the easier it is to assess properly.

Can vested shares or RSUs count as variable income?

Potentially.

Some lenders may consider vested shares or restricted stock units where there is an established history.

They may look at:

employer;

vesting pattern;

historical value;

liquidity;

currency;

and whether awards are recurring.

Others may exclude them.

For senior executives whose remuneration is heavily equity-based, this can materially affect borrowing capacity.

What if stock awards fluctuate with the share price?

That introduces an additional layer of volatility.

The number of shares may be relatively predictable while the value at vesting changes.

The lender may therefore use a conservative figure.

It may also require a longer history to establish a sustainable level.

The borrower should not assume that one unusually strong vesting event will be treated as recurring income.

Can deferred bonuses count?

Potentially, depending on when and how they become available.

A deferred award may not be immediately accessible.

The lender may want to know:

when it vests;

whether conditions apply;

whether payment is guaranteed;

and whether the borrower has an established history of receiving similar awards.

Deferred remuneration can strengthen the broader financial picture without necessarily being usable in full for current affordability.

Does the employer matter?

Potentially.

The lender may take comfort from:

established employment;

employer stability;

sector;

role;

and remuneration history.

A borrower receiving a large recurring bonus from a long-established employer may be assessed differently from someone whose variable income comes from a newly launched business or uncertain arrangement.

Employer strength is not a substitute for income evidence.

But it can provide context.

Does the industry matter?

Potentially.

Some sectors routinely pay a significant proportion of remuneration through bonus or commission.

Examples can include:

financial services;

law;

recruitment;

sales;

technology;

and professional services.

A lender familiar with the sector may better understand the remuneration pattern.

The label “bonus” can mean very different things in different occupations.

Can professionals use variable income?

Potentially.

Professionals can have substantial non-basic income.

A lawyer may receive:

salary;

annual bonus;

partnership distributions.

A doctor may receive:

salary;

overtime;

private practice;

locum income.

An accountant may receive:

salary;

bonus;

profit share.

A lender should assess the actual remuneration structure rather than assuming professional income is always a straightforward salary.

Can partners use variable income?

Potentially.

Partnership income can vary significantly year to year.

The lender may consider:

drawings;

profit allocation;

distributions;

and historic earnings.

This is different from employee bonus income, but the underlying challenge is similar:

what level of earnings is genuinely sustainable?

How do lenders treat variable income after a career break?

This depends on the circumstances.

A borrower may have:

returned from parental leave;

taken a sabbatical;

had an illness;

or temporarily reduced hours.

Recent bonus, commission or overtime figures may therefore look weaker than the longer-term pattern.

Some lenders may be willing to consider the wider history and current return to work.

Others may take a more conservative view.

The reason for the change should be clearly evidenced.

What if variable income has been increasing?

That can strengthen the case.

A borrower whose commission or bonus has grown steadily may have:

progressed professionally;

increased their client base;

moved into a more senior role;

or improved performance.

The lender may still use an average rather than the latest peak.

But a clear upward trend can provide useful context.

What if variable income is falling?

That can weaken the amount recognised.

A lender may be cautious about relying on an older, higher average where recent remuneration is clearly declining.

The current trajectory matters.

A lender’s task is to assess sustainable future affordability, not maximise the historic average.

Does a short history make variable income unusable?

Not always.

A borrower may have recently:

changed role;

moved employer;

started earning commission;

or become eligible for bonus.

Some lenders may require a longer track record.

Others may consider:

prior professional history;

new contract;

current payslips;

and evidence of the compensation structure.

The available options depend on how established the new income appears.

Can future bonus income be used?

Usually, lenders will be more cautious with income that has not yet been received.

A contractual entitlement may provide stronger evidence than an employer’s expectation.

But even a stated target bonus may depend on performance.

Potential income is not the same as earned income.

The lender needs a credible basis before relying on it.

Does variable income help you get a higher income multiple?

Potentially, but these are separate questions.

First, the lender needs to determine how much income it recognises.

Then it applies its affordability methodology.

For example, the bigger difference may be between:

recognising £150,000 of total income;

and recognising £250,000,

rather than whether the lender uses 4.5 or 5 times the final number.

Before focusing on income multiple, establish the recognised income base.

Does a large deposit help if income is variable?

Potentially.

A larger deposit reduces loan-to-value and strengthens the security position.

That can improve lender appetite.

But it does not make uncertain income more sustainable.

The lender still needs confidence that the mortgage payments can be maintained.

Can substantial investments help?

Potentially.

High-net-worth borrowers may have significant:

cash;

investments;

property;

or other assets.

These can provide wider financial resilience.

Some lenders may also consider them as part of an interest-only repayment strategy.

But assets and income should not be confused.

Liquidity can support a strong credit case. It does not turn a one-off bonus into recurring salary.

Can variable income support an interest-only mortgage?

Potentially.

The borrower still needs to demonstrate sufficient income to meet the interest payments.

The lender also requires an acceptable repayment strategy for the capital.

For high-value borrowers, investments or other assets may potentially provide that strategy.

Variable income can help service the mortgage.

It should not be confused with the eventual capital repayment resource.

Can international bonus or commission income be used?

Potentially.

A borrower may receive variable income in:

US dollars;

euros;

Swiss francs;

or another currency.

The lender then needs to assess both:

income variability;

and foreign-exchange risk.

It may apply a reduction to the converted amount or restrict acceptable currencies.

A lender with strong bonus criteria may still be unsuitable if it does not accept the currency.

What if you are a British expat earning commission overseas?

Potentially.

The lender needs to fit:

overseas residency;

foreign-currency income;

and commission-based remuneration.

That combination can narrow the market.

But it does not necessarily make the mortgage unfinanceable.

The case simply requires a lender comfortable with all relevant components.

Can self-employed variable income be treated like commission?

Not exactly.

A self-employed person’s income may fluctuate because of:

revenue;

costs;

accounting periods;

or business performance.

A lender will generally assess accounts or tax information rather than treating the variation as employee commission.

The underlying principle is still sustainability.

But the evidence differs.

What if bonus income is needed for the mortgage to work?

Then it is particularly important to establish lender treatment before applying.

Suppose the borrower requires a £1.2 million mortgage.

Using salary alone, the borrowing is insufficient.

Using established bonus income, the case works comfortably.

Approaching a lender that recognises very little bonus income could result in an avoidable decline or reduced loan.

Lender selection should therefore reflect the actual income structure.

Does variable income affect remortgaging?

Potentially.

A borrower may have obtained their original mortgage when:

salary was higher;

bonus structure was different;

or overtime was more consistent.

At refinance, the new lender assesses the current position.

If variable income has changed, the borrowing options may change too.

Likewise, a borrower whose bonus or commission has increased materially may have more options than when the original mortgage was arranged.

Can one lender use a different bonus figure from another?

Yes.

This is common.

One lender might:

average two years;

another three;

another use the latest year’s lower figure;

another use a percentage of current bonus.

The borrower and documents are identical.

The recognised income can still differ considerably.

Why might one lender decline while another accepts?

Because lender criteria are not uniform.

One may consider variable income too inconsistent.

Another may see a strong and established remuneration pattern.

A decline should therefore be understood before the case is simply submitted elsewhere.

The key question is whether:

the lender was unsuitable

the income itself does not sustainably support the required mortgage.

What documents are usually needed?

Depending on the income type, a lender might potentially request:

payslips;

P60s;

bonus statements;

commission history;

employment contract;

employer letters;

tax documents;

bank statements;

stock award statements;

and evidence of historic remuneration.

The purpose is to establish both the amount and consistency of the income.

Why does presentation matter?

Because a borrower with substantial variable income can look very different depending on how the figures are presented.

For example:

£100,000 basic salary

may appear modest for the mortgage required.

But the complete remuneration may show:

£100,000 salary

£80,000 recurring commission

£50,000 established bonus

£40,000 annual vested stock.

The lender still needs to assess each component appropriately.

But failing to explain the complete structure can materially understate the borrower’s position.

Variable income should be interpreted, not simply totalled.

How should bonuses, commission and overtime be assessed?

A useful framework is to consider five areas.

1. Type

Is the income bonus, commission, overtime, allowance or another form of remuneration?

2. History

How long has the borrower received it?

3. Consistency

How much does it vary and why?

4. Evidence

What documentation supports the current and historic figures?

5. Lender fit

Which lender’s methodology reflects the genuine remuneration pattern most appropriately?

This is more useful than simply searching for a lender that claims to “accept bonuses”.

How Henry Dannell can help

At Henry Dannell Private Clients, we work with borrowers whose true earnings are not always reflected by basic salary alone.

That can include:

senior executives;

professionals;

sales directors;

partners;

doctors;

international employees;

and other high earners with substantial variable remuneration.

Our role begins by understanding the complete income structure.

That can include:

basic salary;

cash bonus;

commission;

overtime;

allowances;

vested shares;

deferred remuneration;

and

other recurring income.

We can then assess how different lenders may interpret those components.

For one borrower, the issue may be a lender using only a small proportion of annual bonus.

For another, regular commission may represent most of their earnings.

A doctor may rely on overtime and additional shifts.

A senior executive may receive substantial stock-based compensation alongside cash remuneration.

The objective is not to persuade a lender to treat uncertain income as guaranteed.

It is to make sure established and sustainable variable income is recognised for what it genuinely represents.

The takeaway

Bonuses, commission and overtime can all potentially support a mortgage application.

But lenders may treat each type of variable income differently.

They may consider:

history;

consistency;

frequency;

contractual position;

employer;

trend;

and supporting evidence.

One lender may use a large proportion of the income.

Another may use much less.

The useful question is therefore not simply:

“Does this lender accept bonus or commission?”

It is:

“How does this lender calculate the sustainable level of my variable income, and does that methodology reflect how I actually earn?”

For borrowers whose remuneration extends well beyond basic salary, that distinction can materially affect the mortgage available.

Variable income does not need to be treated as unreliable simply because it changes. The relevant question is whether there is enough evidence to show that it forms a genuine and sustainable part of the borrower’s earnings.

Important information

This article is for general information only and does not constitute personal mortgage, legal, tax, investment or financial advice.

Mortgage availability, affordability calculations and the treatment of bonuses, commission, overtime, allowances, share awards and other variable remuneration depend on the borrower, property and lender at the relevant time.

Variable income is not guaranteed and may fall or stop in future.

Future earnings, bonuses, commission and equity awards cannot be guaranteed.

A mortgage or other property-backed borrowing is secured against property. Your property may be repossessed if repayments are not maintained.
