Level 3 Mechanical Engineering Apprentice (Lincoln)

Join us and help be the energy behind the change.

National Gas is the backbone of Britain's energy system. We're responsible for securing the UK's energy, whilst leading the way to a net-zero future. 
 
This four year Mechanical Engineering Apprenticeship is based at our site in Lincoln. You’ll develop the skills needed to help maintain the safe and reliable operation of the gas network.

National Gas runs the huge network of pipes that move gas around the UK, helping supply power stations, factories and around 23 million homes. As an apprentice, you become part of the team that keeps all of this running smoothly, which means your work actually helps keep the lights on and heating working for people across the country.

What you’ll be doing

To kick start your Mechanical Engineering apprenticeship with National Gas, you’ll begin your journey at college, developing the core mechanical principles and engineering fundamentals that will set you up for success. You’ll build confidence in areas like mechanical maintenance, engineering fitting and assembling mechanical components, giving you the grounding you need before bringing those skills to life out on site.

During the first eight months of your apprenticeship, you’ll spend Monday to Friday based full‑time at HETA College typically in either Grimsby or Hull, living and learning alongside apprentices from across the country. This weekday residential setup gives you focused time during the working week to grow your technical skills, build your confidence and learn as part of a supportive cohort - while still returning home at weekends. Throughout this time, you’ll stay closely connected with National Gas through regular check ins with your local team, making sure you feel supported and on track. Once you complete this initial learning phase, you’ll return to site to put your knowledge into practice, gaining real hands on experience with our expert technicians.

By the end of the programme, you’ll know how to inspect, repair and service the mechanical systems that keep our gas network running smoothly, from valves and pumps to rotating machinery and pipework. You’ll learn how to spot problems, fix faults and ensure equipment is operating safely and efficiently. You’ll build a solid understanding of how our compressors, pipelines and other assets work to ensure the whole network can run at its best, all while learning to work safely in specialist environments. 

You’ll build skills in:

•    Maintaining pumps, valves, compressors and other mechanical equipment 
•    Fitting, assembling and taking apart mechanical components 
•    Using precision tools to measure, check and test machinery 
•    Finding mechanical faults using tools and data 
•    Understanding and following essential safety processes

One day you might be inspecting machinery, the next you might be replacing worn-out parts or helping with upgrade work. You’ll be working with real equipment in real environments, and no two days will feel the same.

We’ll work closely with you and your college to review your progress, providing regular feedback and guidance. You’ll have a personalised training plan that ensures you get the support and development you need throughout your apprenticeship.

About You

If you’re ready to kick-start your career with top-notch training and hands-on-experience, this is a great time to join National Gas. A willingness to learn and put yourself out there will be essential for making the most of this opportunity and give you the tools you’ll need to set yourself up for an exciting and long-lasting career with us.  

This apprenticeship is perfect for someone who is proactive and thrives on ‘getting stuck in’. You’ll be curious about how things work and enjoy problem solving. You’ll take pride in your work and be excited by the opportunity to learn how we keep energy flowing safely and efficiently. 

The Essentials

This is a 4-year fixed-term apprenticeship. To be considered for this scheme, you’ll need:

•    5 GCSEs grade 5-9/C or above (predicted grades if you are yet to achieve) MUST include maths, English Language and Science (or equivalent)
•    A cover letter is essential to help us understand why you're a great fit for the role. Check out our guidance below! 
•    You’ll need to be comfortable with travel and overnight stays. This means that you’ll need to have a driving license by the time you would be joining us (September 2026!).
•    You'll need to have permanent right to work in the UK for the entirety of this programme, as we are unable to offer visa sponsorship for this role. 
•    As you’ll be working on Critical National Infrastructure, you’ll also need to pass enhanced National Security Vetting, meaning you’ll need to be able to provide a 5-year UK address history. Your eligibility for certain roles may be affected by your place of birth, nationality, current or former citizenship, and any residency you hold or have held. Further details are available at United Kingdom Security Vetting: clearance levels - GOV.UK (www.gov.uk)

Studies suggest that women tend to apply only if they meet 100% of the criteria. If you resonate with our mission, the role excites you and your skills align, we encourage you to apply.

•    Why you’re interested in working at National Gas

Your next steps…

You'll be offered additional support and guidance throughout the application process by our Early Careers team. Eligible applications will be reviewed by a human, every step of the way.
You’re only able to apply for one of our apprenticeship schemes, so please consider this carefully. When reviewing your application, if we feel you might be a good fit for something else, we'll be sure to let you know.

If your online application is successful, you’ll be invited to complete a virtual solo-interview. The final stage is then an in-person Assessment with the team you’ll be joining, so please keep this in mind. Support is available towards travel costs if required.

Applications close on Sunday 8th March 2026.  Each year, we receive a large volume of applications, so we'd encourage you to apply early.
