We’re home to additionallengths.com, our direct-to-consumer destination for luxury extensions, and Remi Cachet, our global professional hair extension brand, setting the industry standard for premium hair, seamless results, and ethical sourcing. As a certified B Corp, we’re proud to meet the highest standards of social and environmental performance, transparency, and accountability.

About The Role
As our first ever Demand Planner, you will sit at the heart of the business, connecting commercial ambition with operational reality across both UK and international markets. As Additional Lengths continues to expand into new territories, this role will provide a clear, joined-up view of demand by channel and by country, ensuring stock decisions are informed, planned and scalable. By improving forecast accuracy and forward visibility across multiple markets, the Demand Planner will enable better, faster decisions as the business grows internationally.
Some of your key responsibilities will include:
- Demand Forecast Ownership
- Develop, own and maintain a single, credible demand forecast across UK and international territories, by channel and product range, that the business can trust.
- Build and manage a robust baseline forecast using historical sales data and trend analysis.
- Incorporate promotions, campaigns, NPD launches, growth targets and wider market activity into forward-looking demand plans.
- Translate incomplete, conflicting and fast-moving commercial inputs into a clear, explainable view of demand.
- Make assumptions explicit, track forecast accuracy, and continuously improve forecast performance over time.
- Apply appropriate forecasting techniques (e.g. baseline forecasting, uplift modelling, scenario planning) suitable to a fast-growth, multi-SKU environment.
- Partner closely with Commercial, Marketing, NPD, Finance and Operations to ensure demand is visible before key decisions are made.
- Challenge promotional activity and launch plans constructively using insight, data and scenario modelling.
- Enable the business to pursue growth opportunities by clearly highlighting trade-offs, risks and operational implications.
- Ensure NPD forecasts are underpinned by realistic volume assumptions and measurable demand signals.
- Support margin understanding, where demand decisions impact profitability.
- Lead the demand side of the S&OP process, ensuring demand inputs are structured, forward-looking and decision-ready.
- Define what high-quality demand planning input looks like and embed this into business routines.
- Bring a joined-up demand view into forums to avoid reactive or backwards-looking.
- Work in partnership with the Operations Director to improve cadence, clarity and effectiveness of S&OP discussions.
- Help build a culture where decisions are made with foresight, not hindsight.
- Establish, embed and continuously improve the demand planning approach, ensuring it remains fit for purpose as the business scales.
- Deliver clarity and consistency without over-engineering processes in a fast-growth environment.
- Work effectively and build on imperfect systems and spreadsheets.
- Define what “good” looks like today and shape how demand planning should evolve as the business scales.
- Avoid unclear forecasting and create a scalable, repeatable planning capability over time.
About You
We’re ideally looking for someone with:
- Proven demand planning experience within a fast-growth, multi-sku, multi-channel environment.
- Strong UK market expertise, with some exposure to international territories.
- Ability to build and manage robust baseline forecast using sales data and trend analysis.
- Experience partnering with cross-functional teams such as NPD, Marketing and Commercial to provide credible forecasts for product launches, and constructively challenging promotional and launch plans.
- Ability to structure demand inputs into forward-looking, decision-ready outputs.
- An analytical, structured, commercially aware individual, with the ability to comfortably influence and challenge.
Whilst the above describes the type of person we’re looking for, we have great training and development capabilities, so even if you don’t tick every point, we’d still love to hear from you.
What’s On Offer
We believe great work deserves great rewards. Alongside a competitive salary, you’ll enjoy a range of benefits designed to support your wellbeing, growth, and lifestyle:
- A collaborative and innovative culture where you can be your authentic self, thrive creatively, and grow professionally.
- Exciting career development opportunities within a fast-growing, award-winning business.
- 25 days’ annual leave plus public bank holidays, giving you time to rest and recharge.
- Private health insurance through Vitality, supporting your long-term health and wellbeing.
- A healthcare cash plan to help with everyday healthcare costs.
- An enhanced pension scheme with salary sacrifice options, helping you plan for the future.
- 40% staff discount on Additional Lengths products and 20% off third-party brands.
- A company-wide bonus scheme, recognising shared success.
- Death in service cover providing four times your salary for peace of mind.
- Enhanced family leave and occupational sick pay, because looking after our team matters.
- Access to our Employee Assistance Programme, offering confidential wellbeing and mental health support whenever you need it.
