About This Service
Commercial Heating Services Done Right
Reliable heat with predictable running costs and minimal downtime — that’s the outcome our commercial heating work delivers. JLN installs, services and repairs commercial boilers, plantroom pipework and distribution so offices, shops and light-industrial sites across Coventry and the West Midlands remain safe, efficient and compliant. Accredited engineers, manufacturer approvals and 19 years’ experience ensure projects finish on time with full test packs and handover documentation.

Our Process
How It Works
Site survey & load assessment
We inspect plantrooms, measure heat loads, review existing distribution and produce a compliance-led specification with options for efficiency and redundancy.
Install, upgrade or repair
Certified engineers carry out works to programme — new boilers, cascade systems, low-loss headers, pump sets and controls — with daily parts deliveries to keep downtime low.
Commissioning & handover
Full testing, flue and gas-tightness certificates, O&M manuals and recommended service schedules are supplied. Optional service plans and emergency cover are offered after handover.
