We’re so much more than an energy company. We’re a family of brands revolutionising how we power the planet. We're energisers. One team of 21,000 colleagues that's energising a greener, fairer future by creating an energy system that doesn’t rely on fossil fuels whilst living our powerful commitment to igniting positive change in our communities. Here, you can find more purpose, more passion, and more potential. That’s why working here is #MoreThanACareer.

We do energy differently - we do it all. We make it, store it, move it, sell it, and mend it.

About your team:

At British Gas, our mission is to sell it and mend it.

We’ve been powering the UK’s homes and businesses for over 200 years – but supplying energy is just part of what we do. We’re making the UK greener and more energy efficient, getting closer to Net Zero. By using clever tech like thermostats, heat pumps, solar panels and EV chargers, we’re making it cheaper and easier for our customers to reduce their carbon-footprint.

We’re looking for an ACS qualified Installation Surveying Engineer (Retrofit Assessor) to join our NEST team, covering South Wales, North Wales and Mid Wales.

Please note: this is a 9-month secondment/fixed-term opportunity.

£48,557 pro rata

Secondment/Fixed term, Full-time, 40 hours per week

Location: Field based in the South Wales, North Wales and Mid Wales regions

Company Benefits

What you’ll be doing:

  • In this role, you’ll support the safe and effective delivery of the NEST Fuel Poverty Scheme, completing technical surveys, assessments and inspections to help customers improve the energy efficiency of their homes.
  • You’ll work to high standards of quality, safety, efficiency and customer satisfaction, while supporting business and personal KPIs.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
