Workforce-as-a-Service (WaaS): The Future of Flexible Green Talent Solutions 🌍💼
If you’re scaling a retrofit, renewables, or FM business, you’ve probably hit the same roadblock as everyone else:
❌ Skills shortages
❌ Project-based hiring needs
❌ Compliance headaches
❌ Slow, traditional recruitment models
This is where Workforce-as-a-Service (WaaS) comes in. It’s not just recruitment—it’s a scalable, fully managed workforce solution that gives you access to qualified, compliant, and job-ready professionals on demand.
At SERT, we’re integrating WaaS into our green skills and workforce strategy, ensuring businesses can quickly deploy skilled workers for retrofit, renewables, utilities, and FM projects—without the pain of traditional hiring.
🚀 What is Workforce-as-a-Service (WaaS)?
Think of WaaS as a subscription-based, on-demand workforce solution—like a fully managed talent pool that adapts to your business needs.
Instead of:
❌ Waiting months for permanent hires
❌ Juggling subcontractor compliance & payroll
❌ Worrying about project staffing gaps
You get:
✅ A vetted, trained workforce on-demand
✅ End-to-end compliance, onboarding & payroll handled
✅ Seamless scalability for seasonal or project-based work
It’s recruitment + training + workforce management, all in one package.
🔥 Why WaaS is the Future for Green & Retrofit Sectors
1️⃣ Demand is Outpacing Supply
The UK needs tens of thousands of skilled workers for:
🔹 Retrofit coordination & installation (PAS 2035)
🔹 Smart metering & EV infrastructure
🔹 Solar PV & heat pump deployment
🔹 Energy auditing & FM sustainability roles
With WaaS, businesses don’t have to wait—we maintain a ready-to-deploy workforce.
2️⃣ Project-Based Hiring Needs Flexible Solutions
Many companies don’t need full-time hires—they need skilled workers for 6-12 month projects.
📍 A housing association may need retrofit teams for an ECO4 rollout.
📍 A utilities firm may need smart meter engineers for a region-specific contract.
📍 A solar PV installer may have a peak period in summer and need 50 extra workers.
With WaaS, you get instant workforce scale-up or down, with no long-term commitments.
3️⃣ WaaS Simplifies Compliance & Payroll
Managing a workforce in a highly regulated industry is tough.
❌ IR35? CIS? PAYE? Umbrella?
❌ Training & accreditation tracking?
❌ Insurance & risk management?
We handle it all:
✔️ Pre-vetted & accredited workforce
✔️ Payroll & tax compliance (PAYE, CIS, or Umbrella)
✔️ Full workforce management & reporting
Businesses get work-ready professionals, with zero administrative burden.
4️⃣ WaaS Saves Time & Cost
💰 Average cost to hire a skilled worker: £4,000+
⏳ Average hiring timeline: 6-8 weeks
🔁 Annual turnover risk: High in project-based roles
With WaaS:
⏳ Deployment is instant—no hiring delays.
💰 You only pay for what you use—optimising costs.
