Offices, Warehouses & Commercial Premises

Alongside domestic work, UltraOne designs and installs heating and cooling for commercial sites across South & West Yorkshire — from multi-split air conditioning in office blocks to commercial boiler installations for larger buildings. Every commercial job gets a full survey and load calculation before we quote, so the system is sized correctly first time.

Commercial premises are charged 20% VAT — the domestic 0% air con relief doesn't apply to commercial installs.

Multi-Room & Multi-Split AC Design

Full cooling design for offices and commercial units, sized against a proper room-by-room load calculation rather than guesswork.

Commercial Boiler Installation

Single and cascade boiler systems for larger commercial heating demands, installed and certified to current regulations.

Site Surveys & Load Calculations

A proper pre-quote survey on every commercial enquiry, so the price you're given reflects the building, not an estimate.

Planned Maintenance

Ongoing servicing for commercial heating and air conditioning to keep systems compliant and running efficiently.
