Office Manager

Portsmouth based – 5 days a week on site

Open to contract (Inside IR35) or Permanent

Up to £38,000 per annum

Immediately available required

As the next Office Manager based in our Portsmouth office, you'll play a key role in helping us build the UK's go-to home improvement marketplace. You'll be the person who makes the office genuinely great to work in – owning the space end-to-end, bringing our hybrid working model to life, and making sure every employee who walks through the door feels set up to do their best work. This isn't a background role: you'll be visible, hands-on, and central to how our culture shows up in person.

Responsibilities:

• Owning the day-to-day running of the Portsmouth site – from reception and mail to seating plans and internal moves – so the office hums along without anyone having to think about it.
• Being the culture carrier on the ground: activating the space, setting the atmosphere, and making sure every corner of the office reflects how we work and who we are.
• Planning and running internal events, social activities, and all-hands meetings that bring people together and make coming in feel genuinely worthwhile.
• Managing vendor relationships and site budget – cleaning, catering, maintenance, security – holding partners to a high standard and making sure the office stays safe, stocked, and sorted.
• Serving as the designated Health & Safety officer for the site, keeping all documentation, risk assessments, and fire safety protocols up to date and fully compliant.
• Overseeing office supplies, tech accessories, pantry stock, and fleet logistics – so employees always have what they need, without the faff of chasing things down.

Skills and experience:

• Experience in an office management, workplace experience, or facilities coordination role – ideally in a tech or scaling business.
• Strong organisational skills and the ability to juggle multiple vendors, projects, and priorities without dropping anything.
• Clear, confident communication – whether you're dealing with a colleague, a building manager, or a senior leader, you know how to get the right outcome.
• A solid working knowledge of UK Health & Safety requirements; IOSH or NEBOSH certification is a nice-to-have, not a dealbreaker.
