About Our Outside IR35 Renewable Energy Contract Roles
What does a renewable energy contractor do?
Renewable Energy contractors are engaged across the full spectrum of disciplines required to develop, design, construct, commission, and operate renewable energy assets, spanning offshore and onshore wind, solar photovoltaic, hydropower, tidal, and the rapidly growing battery energy storage and hydrogen sectors. The pace of the UK's energy transition and the substantial investment being made in clean energy generation and storage infrastructure has created one of the most active project engineering and management contracting markets in the country. Contractors are engaged at all stages of the project lifecycle: in development for permitting, environmental impact assessment, and grid connection; in design for technical specifications and engineering drawings; in construction for project management, site supervision, and commissioning; and in operations for asset management, performance optimisation, and maintenance.
The skills most in demand across renewable energy contracting reflect the technical requirements of each project phase and technology type. Development-stage contractors include planning and consenting specialists, environmental consultants, and grid connection engineers with knowledge of the UK planning system and the National Grid connection process. Design-stage engineers include electrical engineers with HV and power systems expertise, structural engineers for foundation and tower design, mechanical engineers for turbine and balance-of-plant systems, and geotechnical specialists for offshore and onshore foundation design. Construction and commissioning roles require project managers, site supervisors, and commissioning engineers with relevant health and safety certifications for the working environment. BCAR and GWO certification is expected for most offshore wind site roles.
What is the market like for renewable energy contractors?
The market for Renewable Energy contractors is one of the most dynamic and high-growth segments of the UK engineering and project management contractor market. The UK's legally binding commitment to achieve net zero emissions by 2050, combined with the pace of offshore wind development and the investment pipeline for solar, battery storage, and hydrogen, is generating exceptional and sustained demand for contractors across all disciplines. The offshore wind sector is particularly active, with major programmes at Hornsea, Dogger Bank, and the emerging pipeline of floating offshore wind projects creating large and long-duration contract opportunities. The transition from conventional energy to renewables is also creating strong demand for contractors who can bring oil and gas or power industry experience and adapt it to the renewable energy context. Rates across renewable energy contracting are competitive and in some technical specialisms at the premium end of the engineering contractor market.
What does Outside 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 outside IR35, the engagement is treated as a business-to-business arrangement. The contractor operates through their own limited company, invoices for services, and manages their own tax affairs including corporation tax, self-assessment, and VAT where applicable.
Outside IR35 engagements are assessed against three key factors: the degree of control the client exercises over how the work is delivered, whether the contractor has a genuine right to provide a substitute, and whether there is a mutuality of obligation between the parties. Contracts that demonstrate contractor autonomy, project-based delivery, and the absence of ongoing employment obligations are more likely to sit outside IR35. Since April 2021, responsibility for making this determination sits with the end client for medium and large private sector organisations.
On QualityContracts.co.uk, approximately 28% of roles with a stated IR35 status are classified as outside IR35. The proportion varies by sector and role type, with some disciplines seeing a significantly higher or lower share of outside IR35 opportunities. Each listing on this page displays its IR35 status where provided by the hiring organisation.
What renewable energy roles are usually Outside IR35?
Renewable energy contracts can sit outside IR35 when structured around specific project phases: conducting a feasibility study for a solar farm, managing the grid connection process for a wind development, or delivering the commissioning phase of a battery storage installation. The project-based nature of renewable energy development creates natural engagement boundaries. Developers, consultancies, and EPC contractors commissioning specific project phases are the typical sources.
How much do renewable energy contractors usually earn when working Outside IR35?
Contract rates for renewable energy roles typically range from £400 to £750 per day, depending on the scope of the role, required expertise, and the delivery expectations of the engagement. Rates shown are for outside IR35 engagements and reflect the gross day rate paid to the contractor's limited company before any personal tax obligations.
