Every Assistant Site Manager comes from one of two places.

Route 1: Degree, tidy CV, can build a programme that actually makes sense.
Knows Excel better than most people know their own postcode.
Runs inductions, H&S, paperwork - keeps the job compliant (and everyone honest).

Route 2:
Started on site, maybe as a logistics manager - probably carrying something heavy at some point.
Knows who’s turning up late, what’s going wrong, and why.
Can run an induction off the top of their head - might just need a hand finding the spreadsheet.

This role will take either.

It’s with a prime residential specialist that’s been around 30+ years - quietly getting on with it while others came and went (including recessions, the credit crunch, and everything else thrown at the industry).
Small team. Long-serving people. Most of the senior site managers started on the tools and never left.

They’re not hiring because of churn. They’re thinking about the next generation.

The role:
Assistant Site Manager on a £3.5m refurb in Phillimore Place, Kensington - Just starting - 18-month programme
Proper Cut & Carve
• Demo + new double rear extension
• Full M&E + AV
• Roof strip and replacement (lead & slate)
• Levelling floors throughout

You’ll be No.2 to a hands-on Site Manager (carpenter by trade, serious about levels and datums).
He builds it right. You make sure everything else doesn’t unravel.

Must have:
• SSSTS, CSCS, First Aid
• Some organisation (however you’ve learned it)
• A lot of ambition - they promote from within

£40–50k + package type of role
Whichever route you came from…this is where it either clicks, or it doesn’t.
Please get in touch if this sounds like you.
