Stelrad: The UK's Radiator King

How a 125-person team dominates a $36M niche and what it means for industrial manufacturing.

While Silicon Valley obsesses over SaaS margins, Stelrad quietly commands the UK's radiator market with 125 employees and $36.3M in revenue. They aren't selling software—they're selling warmth, and they're doing it better than anyone else.

"In a world of hyper-specialization, Stelrad proves that dominating a single, unsexy vertical is a more defensible moat than chasing scale."

The SEO Moat

Stelrad captures 62% of its traffic organically. Their keyword strategy isn't accidental—it's engineered. They rank for 'room by room heat loss calculator' (680 monthly searches) and 'radiator sizing chart,' turning utility into acquisition. They don't just sell radiators; they sell the tools to buy them, capturing high-intent users at the exact moment of research.

B2B vs. B2C Duality

With 79.5% of traffic undefined (likely UK-centric), Stelrad bridges two worlds: the homeowner DIYer and the professional trade. Their 'Trade' section isn't an afterthought—it's a dedicated revenue stream. By catering to architects and builders via Specification Managers like David Scarlett, they secure bulk contracts that individual consumers can't provide, creating a stable B2B backbone under a B2C brand.

The tech stack reveals a modernizing legacy. They use Vite and Webpack for build optimization, Tailwind CSS for design consistency, and even PWA capabilities for offline access. This isn't a dusty PDF catalog online; it's a dynamic, fast-loading experience that respects the user's time—critical for trade professionals on job sites.

  • Revenue per employee: ~$290k (high for manufacturing)
  • Direct traffic (28%) signals strong brand recall
  • Trustpilot reviews (4,005) build massive social proof
  • Social presence spans Twitter to Instagram, targeting different demographics
They don't chase global expansion (UK-centric focus)
Mastery of a localized supply chain
No flashy venture capital funding rounds
Profitability over growth-at-all-costs
Avoids complex IoT/smart home integration (for now)
Focus on core competency: manufacturing quality radiators

The Unsexy Giant

Stelrad isn't waiting for a tech disruption; they are the standard. For investors, this is a cash-flow positive asset in a recession-proof category. For founders, it's a lesson in depth over breadth.

Faultless from order to delivery

Really good looking radiator which was easy to specify from information contained in the on-line catalogue. Delivery inclusive price, shipped on same day and received within a couple of days from order. Delivery carried out by two well presented and polite guys. Just excellent all round.
