From the field
The same lessons come up again and again from people actually doing the job:
People think it's just stuffing insulation into walls. Doing it properly — no gaps, no cold spots, the right materials fitted right — is what actually makes a building efficient. A bad install wastes the whole point. There's real skill and care to getting it right.

It's a green trade riding a big wave. Net-zero targets and government schemes are pushing to make millions of buildings efficient, so there's strong, growing demand. It's purpose-driven work — I'm keeping homes warm and cutting carbon at the same time.

It's accessible — I was trained on the job, no degree — and there's a real future in it because of the retrofit drive. There's a path too: I'm a team leader now, and plenty of installers go self-employed. Buildings always need insulating, especially with energy bills high.
