Before any comparison is useful, one fact has to come first: whether you are allowed to pay a proofreader at all depends on which UK university you attend, and the sector genuinely contradicts itself. At one named institution paying a professional to proofread your dissertation is a misconduct offence. At another it is permitted by default. At a third it is permitted but must be declared at submission. Read your own policy before you read a single price list, because the wrong purchase here is not a waste of money — it is an academic misconduct case.

Three named UK universities, three incompatible rules
Sheffield Hallam University — permitted by default. Its Guidelines on third-party proofreading for undergraduate and postgraduate taught students state that “third-party proofreading is allowed for any piece of academic writing unless stated otherwise”, with any prohibition appearing in the module handbook. It also defines third-party proofreaders broadly: “professional proofreaders, fellow students, friends or family members”.
University of Nottingham — permitted, but declare it. Its proofreading regulation recognises that “students may wish to ask a third party to proofread work prior to submission”, and then adds the condition most students never hear about: “at the point of submission, students will be expected to declare whether or not they have had their work proofread and if so, indicate that the proofreader has worked within the regulations’s restrictions.”
University of Reading — forbidden. Its policy on the use of editorial and proof-reading services states that “students are not permitted to use another person (‘third party’) to proof-read or edit their assessed work”, and spells out that this includes “a friend, family member, classmate, or a professional or paid proof-reading or editorial service”. Doing so “is an offence under the University’s Academic integrity and misconduct regulations”. Grammar and spell-checking software such as Grammarly or Word’s built-in functionality remains allowed, with a warning to watch for distortion of intended meaning. There is one narrow exception, for research-degree students where proofreading happens during the publication process for part of a thesis — which does not help an undergraduate.
Three universities. Allowed, allowed-with-declaration, and a misconduct offence. There is no UK-wide rule to fall back on, and no service can tell you which regime you are in.

The mismatch nobody tells you about: identify is not correct
Even where proofreading is permitted, what a proofreader may do is drawn far more tightly than what a commercial editing service sells. Sheffield Hallam publishes both lists, and reading them together is instructive.
A proofreader may: identify punctuation, spelling and typographical errors; identify grammatical and syntactical errors and anomalies; identify formatting and layout errors and inconsistencies such as page numbers, font size, line spacing, headers and footers; identify errors in labelling of diagrams, charts or figures; highlight overly-long or complex sentences or paragraphs, especially where meaning is ambiguous; draw attention to repeated phrases or omitted words; and draw attention to inaccurate or inconsistent referencing.
A proofreader may not: add content in any way; rewrite passages to clarify meaning; rearrange or re-order paragraphs to enhance structure or argument; change any words or figures except to correct spelling; check or correct facts, data, calculations, formulae, equations or computer code; implement or alter the referencing system; re-label diagrams; reduce content so as to comply with a specified word limit; make grammatical, syntactical or stylistic corrections; or translate any part of the work into English.
Read those two lists next to each other and the operative distinction appears: a proofreader may identify a grammatical error but may not correct it. Now read what a commercial service sells. Scribbr states that every order combines proofreading and editing, covering language errors in spelling, punctuation, grammar and syntax, plus academic style and conventions, delivered as feedback and suggestions in Word Track Changes.
Those are not the same activity. A service making tracked stylistic and grammatical corrections is doing more than Sheffield Hallam’s list permits a proofreader to do — even though Sheffield Hallam permits proofreading. The industry sells “proofreading and editing” as one product; universities regulate proofreading and editing as two different things, one allowed and one not.
The practical consequence: if your policy permits proofreading, you are responsible for keeping the engagement inside it. That means asking the service for identification and comments rather than accepting rewrites, reviewing every tracked change individually, and making the changes to your master copy yourself. Sheffield Hallam puts that duty on you explicitly — the student “must take responsibility for choosing what advice to accept, and must make the changes to the master copy of the work him/herself”, and it is “the student’s responsibility to prove that a proofreader has adhered to” the guidelines, which is why it advises keeping both the original and the submitted copy.
What the services actually publish about price
Here is a finding that ought to be in every comparison and is in almost none: none of the three main services publishes a headline rate you can read without submitting your document.
Scribbr routes its core proofreading and editing price through an instant-quote calculator rather than a published per-word rate. What it does publish are its add-ons, in pounds: a Structure Check and a Clarity Check each start at £0.0055 per word, APA formatting is £1.00 per page, customised formatting starts at £1.95 per page per item, and citation editing is £2.20 per source. Turnaround runs from same-day at 3, 6 or 12 hours through 24 hours, 3 days and 7 days, with faster delivery costing more. Note also that its APA formatting service states editors “cannot make changes to the content of your paper” — the service itself draws a line, and it is a narrower one than its marketing implies.
Proofed‘s prices page now leads with business and managed-services plans; a per-document consumer rate is not published there, though it describes offering “a full range of proofreading and editing plans, from pay as you go for single documents to managed services”.
PaperTrue‘s pricing page loads but does not serve its rate table in the page content, so a student comparing on price cannot do so from the page alone.
Two things follow. First, treat any figure you see quoted in a blog as unverified — we could not verify a single core per-word rate from the services’ own pages in August 2026, and we are not going to invent one. Second, get quotes from at least two services on your actual word count and turnaround before deciding, because the variables that move the price — length, deadline and add-ons — are exactly the ones a headline rate hides.

The recommendation
Do nothing until you have read your own university’s proofreading policy, and if it forbids third-party proofreading, stop there — the decision is made and no service is worth the risk.
If your policy permits it and requires a declaration, as Nottingham’s does, use a service, keep the engagement to identification and comments, review every change yourself, and declare it. Scribbr is the most transparent of the three on what it does and how it returns work, and its published add-on prices at least let you model part of the cost; get a quote on your real word count before committing.
If your policy permits it and you are choosing between paying and not paying, spend the money only on a finished document, once, and only after your own consistency pass — a proofreader charging by the word should not be finding errors you could have found for free.
And whichever regime you are in, the one thing every UK university permits is software you run yourself on your own draft. Reading’s policy, the strictest of the three, says so explicitly while banning every human option. That is not a consolation prize: consistency errors accumulated over 10,000 words are found far more reliably by a machine than by a tired reader, and they are found in week six rather than in submission week.
Cheaper things to fix first
Most of what students pay proofreaders to catch is not prose at all. Referencing inconsistency is the biggest single category, and it is entirely automatable — our guide to Harvard referencing covers the rules, and note that Sheffield Hallam’s list expressly forbids a proofreader from implementing or altering your referencing system, so this is work you must do anyway. Accidental similarity is the second, and a self-check before submission finds it while there is still time to fix it honestly. Over-length is the third, and it is another thing Sheffield Hallam bars a proofreader from touching — you cannot pay someone to cut you down to the limit, so check what your department counts using our survey of dissertation word counts across UK universities and plan the cut yourself.
If what you actually need is not polishing but the chapters themselves, Tesify structures and drafts your dissertation with you, maintains the bibliography in your citation style as you cite, and checks your drafts before your university does — all inside your own workspace, with everything staying 100% written by you. It is free to start, and it removes exactly the classes of error a proofreader is not permitted to fix for you.

Frequently asked questions
Is it allowed to pay someone to proofread my dissertation?
It depends entirely on your university. Sheffield Hallam allows third-party proofreading “for any piece of academic writing unless stated otherwise”. The University of Reading prohibits it outright, including friends and family, and treats it as an offence under its academic integrity and misconduct regulations. There is no UK-wide rule.
Do I have to declare that I used a proofreader?
At some institutions, yes. Nottingham expects students to declare at the point of submission whether their work has been proofread and to indicate that the proofreader worked within the regulation’s restrictions. Where a declaration is required and you do not make one, the use itself becomes the problem.
What is a proofreader actually allowed to change?
Less than most services sell. Sheffield Hallam’s list permits a proofreader to identify spelling, punctuation, grammatical and formatting errors and to draw attention to problems — and forbids rewriting, reordering paragraphs, changing words other than spelling, altering the referencing system, cutting to a word limit, or making grammatical, syntactical or stylistic corrections.
How much does dissertation proofreading cost in the UK?
None of the main services publishes a core per-word rate you can read without requesting a quote. Scribbr publishes add-on prices — Structure and Clarity Checks from £0.0055 per word, APA formatting £1.00 per page, citation editing £2.20 per source — and prices the core service through a calculator. Get two quotes on your actual word count rather than trusting a figure quoted elsewhere.
Is Scribbr proofreading allowed by UK universities?
Where third-party proofreading is permitted at all, a service can be used within the limits your policy sets. Where it is prohibited, as at Reading, using any paid service is a misconduct risk regardless of how the service describes itself.
Can my friend or family member proofread my dissertation instead?
Not automatically, and this catches people out. Both Sheffield Hallam and Reading define third parties to include friends and family, so an unpaid favour is governed by exactly the same rule as a paid service.
Is using Grammarly or Word’s grammar check allowed?
Generally yes, and notably it remains allowed even under Reading’s strict policy, which permits grammar and spell-checking software while banning human proofreaders. Reading does warn about the risk of distorted meaning, which is a real hazard with technical terms.
Can a proofreader cut my dissertation down to the word limit?
No. Reducing content to comply with a specified word limit appears explicitly on Sheffield Hallam’s list of things a proofreader may not do. Cutting is your job, and it is an editing judgement rather than a clerical one.
What should I keep as evidence if I use a proofreader?
Both your original file and the copy you submit, plus the tracked-changes version you received. Sheffield Hallam puts the burden of proving that a proofreader stayed within the guidelines on the student, which is impossible without those files.
Is proofreading worth paying for at all?
Only on a finished document, only where your policy allows it, and only after you have fixed the automatable layers yourself. Referencing consistency, similarity and length are the three biggest sources of lost marks, and a proofreader is either forbidden from fixing them or the most expensive way to do it.
