Preventative Maintenance
Plans & Contracts

  • Rapid response and emergency prioritisation - your contracts jump our call-out queue
  • Proactive servicing to prevent expensive failures and improve efficiency
  • Compliance made simple - we provide written records, certificates, and safety checks

Keep your commercial plumbing, heating, and gas systems reliable, efficient and compliant - without the hassle. Since 2010, GasWise has supported businesses across North Oxfordshire and surrounding areas like Warwick, Leamington Spa, and Daventry. Our Gas Safe & OFTEC-registered engineers design practical maintenance programmes that reduce downtime, cut emergency call-outs, and protect your bottom line.

Why Preventative Maintenance Matters

Commercial systems work harder and face greater wear than domestic ones. A planned maintenance schedule detects early faults, prevents system failures during peak hours, improves energy efficiency, and extends the life of boilers, pumps, valves, and pipework. For businesses, like schools, offices, landlords, leisure centres, hotels, and industrial sites, preventative care is the most cost-effective way to protect operations and minimise disruption.
