Our Perks and Benefits

Nine23 put people first. We want to do everything we can to help you stay motivated and help you enjoy your working life with some of our benefits we offer to our staff.

Remote Working

It’s time to stop sitting in traffic and wasting time commuting. Nine23 has a small dedicated workspace in Southampton when needed, however after a unanimous vote it was decided that all employees will continue work from home.


Nine23 understands the importance of training and ensuring all team members have the opportunity to learn new and enhance their existing skills therefore Nine23 will contribute towards or fund all training course costs.

Holiday Allowance

Not only do Nine23 give you the standard 24 days holiday entitlement but we like to give our staff some extra time off to refresh over the Christmas holidays and spend time with your loved ones.

Staff Events

It’s important for Nine23 staff to all get together in person for staff events and parties to socialise. Don’t think awkward team building activities, think boat days out on the water and low-key curry nights!


We offer funded counselling sessions to help improve the mental health and wellbeing of our staff. To ensure all sessions are 100% anonymous we use an external counsellor who will not disclose the employees details.

Nine23 Wardrobe

You can wear whatever you feel comfortable in, but to make those daily choices a little bit easier for you can choose our Nine23 clothing such as t-shirts, hoodies, coasts and polos.

Maternity Package

We are extremely supportive of our mums and welcoming new additions to the Nine23 family, therefore we offer an enhanced maternity support package of 100% of salary for the first 13 weeks of maternity leave.

Wellness Check-ins

Every afternoon, we have an informal wellness check-in. A simple “how are you?” tea break. Since working from home it is more important than ever to check-in with each other, now we have a dedicated time slot for this everyday.
