English Editing and Proofreading Services in Spain

Editor World provides English editing and proofreading services in Spain for researchers, doctoral students, business professionals, and authors. You choose your editor from a panel of native English speakers from the USA, UK, and Canada. Every document is edited entirely by a human, and no AI is used at any stage.

Our Spanish clients work at CSIC institutes and at universities from Valencia and Granada to Salamanca, Seville, and the Basque Country. They also include professionals at banks, energy companies, and exporters writing for international partners. For city-specific detail, see our pages for Madrid and Barcelona.

Academic Editing for Spanish Universities and Research Centers

Spanish researchers are under steady pressure to publish in English. ANECA accreditation and the research assessment known as sexenios both reward articles in indexed international journals. A manuscript with unclear English can be returned before it reaches peer review. You choose an editor with experience in your field, so your paper is read by someone who knows its conventions.

CSIC and national research centers

The Spanish National Research Council (CSIC) runs more than 120 institutes across the country, from marine science to materials and food technology. Researchers at national centers such as CNIO in cancer research and CNIC in cardiovascular research also publish heavily in English. Editors on our panel work on their journal articles, reports, and conference papers.

Universities beyond Madrid and Barcelona

We edit for faculty and doctoral students at the University of Valencia and the Polytechnic University of Valencia. Others work at the University of Granada and the University of Seville. Clients also come from the University of Salamanca, the University of the Basque Country, the University of Santiago de Compostela, and the University of Navarra. Fields range from agronomy and tourism research to engineering, medicine, and the humanities.

Madrid and Barcelona

Madrid and Barcelona have Spain's largest concentrations of universities and research institutes. Our Madrid page covers Complutense, UAM, UPM, and Carlos III. Our Barcelona page covers UB, UAB, UPF, and the BIST research centers.

Grant applications for Spanish and European funding

Spanish researchers write many proposals in English, including applications to the State Research Agency (AEI), the European Research Council, Horizon Europe, and Marie Skłodowska-Curie Actions. Page limits are strict, and reviewers read quickly. An editor can tighten your aims, methods, and impact sections so every sentence earns its place.

• Journal article editing: Manuscripts for journals indexed in Web of Science and Scopus. See the journal article editing service.
• Doctoral thesis editing: Full theses or individual chapters, including the English sections of international doctorate theses. See the dissertation editing service.
• Grant proposal editing: AEI, ERC, Horizon Europe, and MSCA applications.
• Conference papers and abstracts: Edited to meet word limits and conference style.
• Certificate of editing: Available as an optional add-on for journals that ask for proof of professional editing. See the certificate of editing for details.

Business Document Editing in Spain

Many Spanish companies sell, invest, and report in English. A clear English document builds trust with foreign investors, partners, and customers.

Banking, finance, and listed companies

Large Spanish groups such as Santander, BBVA, Telefónica, and Iberdrola publish annual reports, sustainability reports, and investor materials in English. Smaller listed companies and fund managers follow the same path as they reach foreign investors. Editors check these documents for precision, consistency, and a professional tone.

Energy, infrastructure, and engineering

Spain is a major market for renewable energy and infrastructure. Engineering and construction firms write tenders, technical proposals, and project reports for clients across Europe, Latin America, and the Middle East. Editors with technical backgrounds can improve the language without changing the engineering content.

Tourism, retail, and exporters

Hotel groups, fashion retailers, and food and wine exporters write websites, catalogs, and partner materials for English-speaking markets. Natural, accurate English matters here, because customers notice awkward phrasing right away.

• Annual and sustainability reports: Including reports prepared under GRI and other reporting frameworks.
• Investor materials: Presentations, fund commentary, and shareholder letters.
• Tenders and proposals: Bids for European and international clients.
• Websites and marketing: Product pages, press releases, and catalogs.
• Correspondence and policies: Emails, contracts, and internal policies written in English.

See our business document editing service for more detail.

Proofreading Services in Spain

Proofreading is the final check before a document goes out. A proofreader corrects spelling, grammar, punctuation, and formatting without rewriting your content. It suits documents that are already well developed, such as a manuscript after co-author review or a report ready for publication. See our professional proofreading services.

ESL Editing for Spanish-Speaking Writers

Many Spanish writers work in two or more languages, including Spanish, Catalan, Galician, and Basque. The patterns in their English usually come from the structure of those languages, not from weak writing. An editor who knows these patterns can fix them while keeping your ideas and voice.

False cognates are a common source of confusion. Spanish "actualmente" means currently, not actually, and "eventualmente" means possibly, not eventually. Spanish also uses articles with general nouns, which leads to phrases like "the society" where English uses "society." Long sentences with several linked clauses are natural in Spanish academic prose, but English readers often find them hard to follow.

See our English editing service for non-native speakers, or read about common English writing mistakes Spanish academic writers make and common English mistakes in research papers by non-native writers.

American or British English

Editors apply American English by default. Many European journals and publishers prefer British English, so say so in your submission notes if your target journal expects it. Your editor will then apply British spelling and conventions throughout. For the main differences, see our guide to UK English vs. American English.

Book and Manuscript Editing

Authors in Spain who write fiction, nonfiction, or academic monographs in English use our editors to prepare manuscripts for agents, publishers, or self-publishing. See our book editing services.

Same-Day Editing for Urgent Deadlines

Same-day editing is available 24/7, 365 days a year, including weekends and public holidays, with 2-hour, 4-hour, and 8-hour tiers for qualifying documents. It helps when a grant portal or journal resubmission deadline is close. See our same-day editing service.
