Commercial Heat Pumps & Cascade Installations

Heat pump heating for offices, workshops, farms, holiday parks and multi-unit buildings — retrofit or new build, with cascade systems for sites that need more than one unit can deliver.

Scaled For Commercial Demand

Built For Bigger Heat Loads

We design and install heat pump heating systems for commercial, agricultural and small industrial premises — offices, workshops, farms, holiday parks and multi-unit buildings. Where a single heat pump isn't enough, we design cascade systems, linking multiple units together to deliver the higher heating capacity, resilience and redundancy that larger buildings need.

We cover both retrofit and new build work: replacing ageing oil, gas or electric heating in existing commercial buildings, and designing systems into new construction from the ground up.

  • Retrofit — replacing oil, gas or electric heating in existing commercial buildings
  • New build — heat pump systems designed in from the start for new commercial premises
  • Cascade installations — multiple units linked for higher output, resilience and redundancy
  • Planned maintenance contracts available
  • Reactive breakdown support for commercial premises
  • Free site surveys and fixed-price quotations

Replacing What's Already There

Retrofit Into Existing Buildings

Most commercial buildings we convert are still running on ageing oil, LPG or electric heating. We survey the existing system and fabric, size the replacement heat pump plant correctly for the building's real heat loss, and plan the changeover to minimise disruption to the business while it's happening.

  • Replacing oil, LPG, gas and electric heating in commercial premises
  • Full heat loss survey before any plant is sized or quoted
  • Installation phased to minimise disruption to ongoing business
  • Integration with existing pipework and emitters where practical

New Build Commercial Systems

For new commercial and agricultural buildings, we design the heat pump system in alongside the rest of the build — sizing plant, emitters and controls against the finished building's heat loss rather than retrofitting around decisions made elsewhere.

  • Heat pump system design integrated with the wider build programme
  • Correctly sized plant, emitters and hot water provision from day one
  • Works alongside architects, contractors and other trades
  • Full system drawings and documentation provided before work starts
When One Unit Isn't Enough

Cascade Installations

Larger buildings and higher heat loads often exceed what a single heat pump can deliver. A cascade system links multiple heat pump units together, sharing the load between them and giving the building resilience and redundancy — if one unit needs servicing or develops a fault, the others keep the building running.

  • Higher total output than a single unit can provide
  • Built-in redundancy — one unit down doesn't mean no heating
  • Staged running for efficient part-load performance
  • Scalable design, suited to multi-unit and larger commercial sites

Why It Matters At This Scale

Degree-Level Engineering, Not Just an Installer

BECS was founded by Charles Burbage, who holds a BEng (Hons) in Mechanical Engineering. On a domestic install that background shows up as more accurate sizing — but on a commercial job, where heat loads, pipe runs and plant interactions are far more complex, it's the difference between a system that's been competently fitted and one that's been properly engineered.

Cascade systems in particular reward that kind of thinking: balancing load across multiple units, sequencing them to run efficiently at part-load, and designing hydraulics that don't fight each other, all take real engineering calculation rather than rule-of-thumb sizing. That's the level we design commercial systems to.

  • BEng (Hons) Mechanical Engineering — not just trade-certified
  • Proper load and hydraulic calculations for multi-unit cascade systems
  • Engineering judgement applied to complex retrofits, not just standard patterns
  • The same rigour as our domestic work, scaled up for commercial demands
