Outgrowing your ops? Future-proof your fulfilment with Zendbox 3PL

TL;DR

With warehouse rents now around £11 per sq ft for prime UK industrial space and business energy prices still 75% above pre-2021 levels, many eCommerce brands are struggling to keep operational costs under control. Partnering with a premium third-party logistics (3PL) provider such as Zendbox replaces fixed warehouse overheads with a flexible, data-driven fulfilment model that scales with demand and safeguards both margins and customer experience

‍

The reality

Rents up, margins down

• Prime UK industrial and logistics rents reached approximately £11 per sq ft at year-end 2024. (Savills, 2024)
• Large distribution units averaged £11.50 per sq ft, with prime mid-box rents around £14.80 per sq ft. (Colliers, 2024)
• UK non-domestic electricity prices in Q4 2024 remained about 75% higher than in early 2021. (ONS, 2025)
• Rent reviews and renewals in the UK saw +43% average uplifts during 2024. (SEGRO FY 2024 Results)
• 55% of consumers expect delivery within 48 hours, and 66% of retailers offering same-day delivery report higher conversion. (Retail Economics, 2024) (DeliveryApp, 2024)

Rising space and energy costs are eating into margins, while delivery expectations are compressing fulfilment lead times.  The brands staying profitable are those shifting from fixed leases and static teams to variable, performance-driven 3PL partnerships.

Your warehouse is holding you back

Running a 10,000 sq ft warehouse at £11 per sq ft equates to £110,000 a year in rent before energy, insurance, or staffing; a fixed overhead that typically exceeds £250,000 annually. That’s capital trapped in overhead instead of fuelling brand growth. Each month those funds remain locked in fixed infrastructure is cash that could fuel marketing, product development, or faster international growth. By contrast, outsourcing fulfilment to a 3PL converts those fixed costs into a variable, performance-based expense, improving liquidity and protecting margins as order volumes fluctuate.

Decision framework

When to switch from in-house to 3PL

Ask yourself:

Are warehouse and energy costs rising faster than order growth?
If rent, energy, and staffing exceed 15 % of order revenue, you’re carrying excess fixed cost.‍

Do peak seasons strain capacity or service?
Zendbox flexes space and labour on demand, no new leases or short-term hires.‍

Are internal teams overloaded with fulfilment admin?
Outsourcing pick/pack, returns, and carrier management lets teams refocus on growth.‍

Are delivery times slipping or too expensive?
Zendbox’s 9 pm cut-off and shipping algorithm ensure same-day dispatch at the lowest achievable carrier cost.‍

Do you lack live visibility of inventory and performance?
Zendportal consolidates real-time stock, order tracking, and KPIs into one view.
