The Paperwork Study: What UK Mortgage Lenders Actually Ask For, and When
See which documents are actually required, when each one falls due, and where a set tells you not to send something.
Quick Answer
Of the 832 published packaging requirements Manor Mortgages Direct tracks across 44 lender and sector sets, 546 are due on submission and only 93 fall before a decision in principle, checked September 2026. Payslips and bank statements are the two most requested categories, at 86 and 80 rows.
The detail matters more than the totals. Eighty-one of the 832 requirements are instructions not to send something, spread across 20 of the 44 sets. Only 27 of the 44 sets publish anything at all as a pre-decision-in-principle requirement, so for most sets the paperwork starts at submission.
A requirement here means a position a lender has published on its intermediary pages, not a promise about any individual case. Every application is assessed individually, and a set with a short published list may still ask for more at underwriting. The counts describe the lender and sector sets the firm tracks rather than the whole of the lending population, and no lender is named anywhere in this study.

Nearly one in ten published requirements tells you not to send something
Most people assume a lender's document list is a list of things to gather. It is not, or not only. Of the 832 published packaging requirements Manor Mortgages Direct tracks across 44 lender and sector sets, 81 are instructions not to send something rather than requests for something, checked September 2026.
Those 81 rows sit across 20 of the 44 sets, so slightly under half the sets publish at least one refusal. The tracker splits every row by its effect on packaging: 501 require a document or a piece of information, 111 attach a condition, 139 record no packaging effect, and 81 are do-not-request rows. Read as a whole, a packaging page is as much a filter as a checklist.
The refusals fall into recognisable families. Some concern the format of the evidence, some the source of the money, some work the lender intends to do itself and does not want duplicated in the file. Ten examples, quoted as the tracker recorded them and anonymised so that no lender is identifiable:
What one of the tracked sets says not to send | What kind of instruction it is |
Bank statements on a standard employed or self-employed case | Evidence the set does not want at all |
Bank statements to verify credit commitments | Evidence for a purpose the set handles another way |
Cryptocurrency as a source of deposit, including where converted back into sterling | An unacceptable source of funds |
Deposit from unsecured loans or cryptocurrency | An unacceptable source of funds |
Identity or address documents printed from the internet | An unacceptable format |
Certification of document copies by a solicitor or other professional | Process the set does not require |
Employer's reference as proof of income, and handwritten or amended payslips | An unacceptable format of income evidence |
Draft accounts or tax returns marked in progress | Evidence the set treats as unfinished |
Business plans and cash flow forecasts are not required for portfolio cases | A step the set has removed |
Cladding documentation such as a letter from the building owner or an EWS1 form, sent upfront | Material the set does not want at that stage |
Two things follow for anyone assembling a file. The first is that sending more is not neutral: a set that has published a refusal has told you the item will not help, and in the case of an unacceptable deposit source it has told you something material about the case itself. The second is that the refusals are unevenly distributed, so an instruction that applies at one set says nothing about the next.
There is also a practical read for anyone whose deposit has an unusual history. Several of the do-not-request rows are about where money came from rather than about paperwork, which is why the large deposits question is worth settling before an application is built rather than after. The tracker records the instruction, not the reasoning behind it.
Five sets say do not send bank statements on a standard case
Bank statements are the second most requested category in the whole dataset, and simultaneously one of the most refused. Of the 44 lender and sector sets whose published packaging requirements Manor Mortgages Direct tracks, 5 publish an instruction not to request bank statements on a standard case, while 69 rows across the dataset require them, checked September 2026.
The overall bank statement category runs to 80 rows once conditional and do-not-request rows are counted alongside the 69 requirements. That is the shape of the finding: statements are close to universal, but a small group of sets has published that they do not want them where the case is a standard employed or self-employed one and income is evidenced another way. Some of the refusals are narrower still, aimed at statements produced to verify credit commitments or to support a rental income calculation.
For a borrower, the honest summary is that you should expect to produce statements and should not assume that a set which has not asked for them will never ask. A thin published list is not the same as a short underwriting list. What the data does support is that the number of statements, and the purpose they are being read for, varies more than most people expect.
That variation is why the content of the statements matters as much as the quantity. Our guidance on bank statements and on the things underwriters query covers the ground the tracker cannot: what a reader is looking for once the file arrives. The study measures what is asked for, not how it is assessed.
The payslip split: one latest payslip, or three months
Payslips are the single most requested document category in the study, at 86 rows. They are also where the sets diverge most sharply on volume, and the divergence does not run the way most people guess. Of the 44 lender and sector sets whose published packaging requirements Manor Mortgages Direct tracks, 26 publish a payslip requirement for fixed basic pay, and of those 16 set their minimum at a single latest payslip while 7 set it at three months or three payslips, checked September 2026.
The remaining three of the 26 sit outside that split: one publishes a minimum of two payslips, and two publish a requirement in a form the tracker could not reduce to a number of months or items, such as a latest monthly payslip or four consecutive weekly payslips depending on how the applicant is paid. Those three are excluded from both counts rather than assigned to either. The working behind the two figures is set out in the method section.
The pattern by size of lender is the interesting part. Twelve of the 16 single-payslip sets are among the 18 larger high street and mainstream sets in the tracker, while 5 of the 7 three-month sets sit outside that group, among the building societies and the specialist tier. On this measure the larger institutions ask for less paper on a straightforward employed case, not more.
There are sensible reasons why that might be so, and the tracker does not evidence any of them, so this study does not assert a cause. What it does show is that the phrase "you will need three months of payslips" is not a general truth about the sets tracked here. On fixed basic pay it is a minority position, held by 7 of the 26 sets that publish a figure at all.
Two caveats keep the finding honest. Several sets publish more than one payslip row, so a set counted at a minimum of one may still ask for three where pay is variable, where a bonus or commission is being used, or where the applicant is newly employed. The count above takes the lowest published requirement for fixed basic pay in each set, which is the number a straightforward employed case would meet.
Self-employed evidence: two years is the default, but a third of the sets take one
Self-employed income is the area where published requirements are most consistent, and the consistency is around two years. Of the 44 lender and sector sets whose published packaging requirements Manor Mortgages Direct tracks, 30 state a minimum number of years of self-employed evidence, and of those 19 ask for two years, 10 ask for one year and 1 asks for three, checked September 2026.
The 14 sets that state no minimum are excluded from that denominator rather than counted as refusals. Silence in a published packaging list is silence: it may mean the set does not lend to self-employed applicants, or that the requirement is published elsewhere, or that it is set at underwriting. The study cannot tell those apart, and does not try.
The ten one-year sets are not a random sample. Six of them are buy-to-let sets, where self-employed income is often being evidenced to establish a tax position rather than to carry the affordability calculation, and a seventh is a specialist residential set. That leaves a small number of mainstream residential sets publishing a one-year minimum, which is a real finding but a narrow one.
The single three-year set is a buy-to-let set at a building society, asking for three years of financial accounts. It is the outlier in the distribution and should be read as one set rather than as a trend.
The form of the evidence varies as much as the number of years. Some rows ask for tax calculations with matching tax year overviews, some for finalised accounts prepared by a qualified accountant, some for either. A borrower with one full year of trading and a strong forward position is in a different situation from a borrower with two thin years, which is why the self-employed route is usually a question of matching a case to a published position rather than of gathering more paper.
Almost nothing is due before a decision in principle
Timing is where the published data most contradicts the common experience of applying. Of the 832 published packaging requirements Manor Mortgages Direct tracks, 546 fall due on submission and only 93 fall before a decision in principle, checked September 2026.
The rest are spread thinly across the stages that follow submission: 52 at conditional underwriting, 47 before the full mortgage application, 37 in an initial document pack, 29 before completion and 28 before offer. That is 193 requirements after submission against 546 at it. The submission point carries roughly two thirds of everything published.
The pre-decision figure is more concentrated than the headline suggests. Only 27 of the 44 sets publish any pre-decision requirement at all, and 45 of the 93, just under half, sit with three of the lender groups tracked. For the majority of sets, the published position is that the paperwork begins when the application is submitted.
That has a practical consequence worth stating plainly. A decision in principle from most of these sets is not a document-checked decision, because most of these sets have not asked for documents by that point. Anyone treating an agreement in principle as evidence that the file has been read is reading it as more than the published process supports.
It also explains a familiar frustration. A case can pass a decision in principle comfortably and then meet a substantial document list days later, not because anything changed but because that is where the published requirements were always sitting. If money has moved between accounts in the run-up, the movement itself is easier to explain before that list arrives than after.
What is asked for most: payslips, statements, then identity
The document categories are led by income evidence by a clear margin. Of the 832 published packaging requirements Manor Mortgages Direct tracks across 44 lender and sector sets, payslips account for 86 rows and bank statements for 80, ahead of every other labelled category, checked September 2026.
Below those two the distribution flattens quickly. A general income label carries 33 rows, an identity label 23, employment contracts 22, a deposit and equity label 21, proof of deposit 20, proof of identity 18, pension statements 18, tenancy agreements 16 and an identity and address label 16.
Document category as labelled by the tracker | Rows across the 44 sets |
Payslip | 86 |
Bank statement | 80 |
Income | 33 |
Other | 26 |
ID | 23 |
Employment contract | 22 |
Deposit / equity | 21 |
Proof of deposit | 20 |
General | 20 |
Proof of identity | 18 |
Pension statement | 18 |
Tenancy agreement | 16 |
Identity and address | 16 |
Application data | 12 |
Lender form | 12 |
The labels need reading with care, and this is a limitation of the study rather than a finding. Identity appears under three separate labels, which together carry 57 rows, and deposit evidence under two, which together carry 41. The tracker normalised by the label a requirement was published under, so those groupings are the tracker's, not the lenders'.
A different cut of the same 832 rows is by what the requirement is. There are 535 document rows, 141 rows asking for information rather than a document, 82 lender forms and 74 verification steps. In other words, roughly one requirement in six is not a document at all but a declaration, a form or a check, which is part of why a document checklist alone rarely describes the whole submission.
The larger lenders publish the longest lists
The last finding runs against what the same tracker shows on criteria pages, where specialist lenders tend to publish more detail than the high street. On packaging it inverts. Of the 44 lender and sector sets whose published packaging requirements Manor Mortgages Direct tracks, the 18 larger high street and mainstream sets publish between 24 and 31 requirement rows each, while the remaining 26 sets run from 7 rows to 18, checked September 2026.
Fifteen of the 18 larger sets publish 30 rows or more. Between them those 18 sets account for 530 of the 832 rows in the study, which is close to two thirds of everything captured from just over 40 per cent of the sets. The thinnest published list in the study runs to 7 rows.
The obvious inference is the wrong one. A short published list is not evidence of a lighter process, and the study is explicit that a set with a thin published list may ask for considerably more at underwriting. What a long list does give is predictability, because more of the requirement is stated in advance and less is discovered later.
This matters most for cases that are heading to the specialist tier in the first place. The published packaging list there is thinner on average, so the file is built on what the lender confirms case by case rather than on what it has printed. That is a difference in transparency, and the study does not treat it as a difference in difficulty.
Method, limitations and what the study does not say
The tracker is Manor Mortgages Direct's own record of published lender criteria and packaging requirements, maintained for the firm's advisers and kept current as lenders update their intermediary pages. For this study it holds 832 published packaging requirements across 44 lender and sector sets drawn from 23 lender brands. Of those 832 rows, 803 were read from the lenders' own published intermediary packaging pages and submission guides, and 29 came from existing criteria records already held in the tracker. Everything was captured in September 2026.
A requirement is recorded when a lender has published a position: that a document or item is required, is required conditionally, or should not be sent. A published requirement is not an offer and not a decision. Every application is assessed individually, and a published packaging list describes what a lender says it wants, not what it will conclude about a particular case.
The payslip counts were derived as follows, since the brief for this study calls for the working to be shown. From the 26 sets that publish a payslip requirement for fixed basic pay, the lowest published minimum in each set was taken, expressed in items or months. Sixteen sets have a minimum of one item or one month: these are 12 of the 18 larger high street and mainstream sets, plus four sets from the building society and specialist tiers. Seven sets have a minimum of three items or three months: two of them from the larger group and five from the building societies and specialists. The remaining three sets are excluded, one with a minimum of two payslips and two whose published wording could not be reduced to a number of months or items.
The self-employed counts were derived the same way, taking the lowest published minimum number of years in each set. Thirty of the 44 sets state a minimum; the other 14 are excluded from that denominator rather than counted as refusals.
Silence is treated as silence throughout. Where a set's published requirements do not address a question, that set has no published position on it and is excluded from that question's denominator. A set that has not published a refusal has not refused.
Finding | Figure, with its denominator |
Requirements that say do not send | 81 of 832 published requirements, across 20 of 44 sets |
Sets refusing bank statements on a standard case | 5 of 44 lender and sector sets |
Sets whose payslip minimum is one item or month | 16 of the 26 sets publishing a fixed basic pay requirement |
Sets whose payslip minimum is three items or months | 7 of the 26 sets publishing a fixed basic pay requirement |
Sets asking two years of self-employed evidence | 19 of the 30 sets stating a minimum |
Sets asking one year of self-employed evidence | 10 of the 30 sets stating a minimum |
Requirements due on submission | 546 of 832 published requirements |
Requirements due before a decision in principle | 93 of 832, across 27 of 44 sets publishing any |
Most requested document category | Payslips, 86 rows of 832 |
Rows published by the larger sets | 24 to 31 rows each, across 18 of 44 sets |
Four limitations apply specifically to this study. Requirements were read from published intermediary packaging pages and submission guides, so a lender with a thin published list may ask for considerably more at underwriting and the row counts are not a measure of how demanding a lender is. Document categories are labelled by the tracker rather than by the lenders, and were normalised by label, so near-identical categories can appear under more than one name. The 44 sets are lender and sector combinations, so a single brand can appear once as residential and again as buy-to-let and is counted twice in set-level figures. And every figure describes September 2026: packaging pages change, and a count that is right this month may not be right next.
Lenders are anonymised throughout. The tracker names them so that the firm can count and check, but no name appears in this study, and the counts describe the lender and sector sets tracked rather than the whole of the lending population.
Reading your own position off the data
If you are employed on a fixed basic salary, the study says your payslip position is better than the folklore suggests: 16 of the 26 sets publishing a requirement set their minimum at a single latest payslip, and 12 of those 16 are among the larger sets. If your pay includes bonus, commission, overtime or a new role that has not yet produced a payslip, you sit outside that count entirely, because the minimum recorded is the one a straightforward case would meet.
If you are self-employed, the working assumption from this data is two years, held by 19 of the 30 sets that state a minimum. One full year is a published position at 10 sets, but six of those are buy-to-let sets and a seventh is specialist, so a one-year residential case is working with a narrow set of published options rather than a broad one.
If your case involves an unusual deposit, the useful reading is in the do-not-request rows rather than the requirement rows. Several of the 81 are about acceptable sources of funds rather than about paperwork, and a source that one set has published as unacceptable is a fact about the case that does not change by sending more documents.
If you are anywhere in the process before a decision in principle, the timing data suggests planning for a document list that arrives later than it feels like it should. Only 93 of the 832 requirements fall before that point, and 546 fall at submission, so the quiet stage is not evidence that the file has been examined.
And if a lender has published a short list, read it as less information rather than as less work. The 26 smaller sets publish between 7 and 18 rows each against 24 to 31 for the 18 larger ones, and the study is clear that the difference measures what is printed, not what will be asked.

FAQs
How many documents does a mortgage lender actually ask for?
It depends heavily on the lender. Across the 44 lender and sector sets Manor Mortgages Direct tracks, published packaging lists run from 7 rows to 31 rows per set, with the 18 larger high street and mainstream sets publishing 24 to 31 each. A short published list does not mean a short underwriting list.
Do I need three months of payslips for a mortgage?
Not usually, on fixed basic pay. Of the 26 tracked sets publishing a payslip requirement for fixed basic pay, 16 set their minimum at a single latest payslip and 7 at three months or three payslips, checked September 2026. Variable pay, bonus, commission or a recent job change can move a case out of that minimum.
How many years of accounts do self-employed applicants need?
Two years is the most common published minimum. Of the 30 tracked sets that state a minimum, 19 ask for two years, 10 ask for one and 1 asks for three. Six of the ten one-year sets are buy-to-let sets, so the one-year position is less widely available on residential cases than the raw count suggests.
Are bank statements always required for a mortgage application?
Almost always, but not universally. Bank statements are required in 69 rows across the tracked sets and appear in 80 rows in total, while 5 of the 44 sets publish an instruction not to send them on a standard employed or self-employed case. Expect to produce them unless a set has published otherwise.
When do mortgage documents need to be sent?
Mostly at submission. Of the 832 published requirements tracked, 546 fall due on submission and 93 before a decision in principle, with the remaining 193 spread across the stages from initial document pack through to before completion. Only 27 of the 44 sets publish any pre-decision requirement at all.
Can sending extra documents help an application?
Not reliably, and sometimes the opposite. Eighty-one of the 832 published requirements are instructions not to send an item, across 20 of the 44 sets, covering formats a lender will not accept, sources of funds it will not use and checks it carries out itself. A published refusal means the item will not assist the file.
Summary
Across 832 published packaging requirements from 44 lender and sector sets, most paperwork falls at submission rather than earlier, with 546 rows there and 93 before a decision in principle. Payslips and bank statements dominate the categories. Eighty-one rows tell applicants not to send something. Two years remains the common self-employed minimum, and larger lenders publish longer lists than smaller ones. All figures describe September 2026.
