About Our Inside IR35 HTML Contract Roles
What does a html contractor do?
HTML contractors bring core web development skills centred on the markup language that structures content on the web, typically combined with CSS for styling and JavaScript for interactivity. In practice, HTML as a standalone contractor skill is rarely the primary search term used by clients, who more commonly recruit for frontend developers, web developers, or UI developers with HTML as an assumed competency. Contractors positioning themselves around HTML are most commonly building static websites, email templates, content management system theming, or digital communications for marketing teams, where the output is primarily structured HTML content rather than complex interactive application logic.
The skills expected alongside HTML proficiency in the contracting market depend on the nature of the engagement. Web developer and frontend roles expect HTML alongside CSS and at least one JavaScript framework, typically React, Vue.js, or Angular. Email HTML specialists need knowledge of the significant quirks and limitations of email client rendering, including Outlook's infamous layout constraints, alongside the ability to produce responsive, accessible email templates. For CMS-focused roles, experience with platforms such as WordPress, Drupal, or Contentful, and the ability to work within templating systems and theme architecture, is the primary additional requirement. Accessibility knowledge, specifically the ability to write semantic HTML that supports screen readers and meets WCAG standards, is increasingly expected across all web development roles and represents a genuine differentiator for contractors operating in the public sector market.
What is the market like for html contractors?
HTML contracting sits within the broader web development market, and pure HTML roles are relatively uncommon at the mid to senior end of the contracting market, where the expectation is for broader frontend or full-stack capability. The most active pure HTML contracting market is in email marketing and digital communications, where specialist HTML email development is a recognised and valued skill. Web design and development agencies, in-house digital teams, and marketing departments are the most consistent buyers of contractor HTML expertise. Rates for HTML-focused roles are at the lower end of the web development contracting market, reflecting the relative accessibility of the skill, but specialists in email HTML or accessibility-focused web development can command rates above the standard web development contractor market.
What does Inside IR35 mean?
IR35 is UK tax legislation that determines whether a contractor is genuinely self-employed or working in a manner that resembles employment. When a contract is classified as inside IR35, income tax and National Insurance are deducted at source, typically via an umbrella company or agency PAYE. Headline day rates on inside IR35 engagements are generally higher than equivalent outside IR35 roles to account for the tax and employment cost structure.
Inside IR35 determinations are made where the working arrangements are considered to resemble employment, based on factors including the level of client control, the absence of a genuine right of substitution, and the presence of mutuality of obligation. Since April 2021, the end client is responsible for making this determination for medium and large private sector organisations. Many employers in financial services, government, and professional services assess the majority of their contractor engagements as inside IR35.
On QualityContracts.co.uk, approximately 49% of roles with a stated IR35 status are classified as inside IR35, making it the most common arrangement across the contract market. The proportion varies by sector and role type. Each listing on this page displays its IR35 status where provided by the hiring organisation.
What html roles are usually Inside IR35?
Inside IR35 HTML work is almost always part of a broader frontend development or content production role rather than a standalone contract. When HTML is the primary skill, the engagement typically involves maintaining and updating the client's website content, building email templates within their marketing automation platform, and formatting content within their CMS. Marketing departments and digital teams at large organisations occasionally hire HTML specialists on an inside IR35 basis for ongoing content production.
How much do html contractors usually earn when working Inside IR35?

Inside IR35 rates are typically 15% to 30% higher than equivalent outside IR35 roles to account for tax and national insurance deducted at source by the fee-payer.
