AAC Gas provide specialist commercial and industrial oil services across Merseyside and the surrounding areas. OFTEC registered and working exclusively with commercial and industrial clients, our engineers service, repair, and maintain oil-fired heating systems, oil boilers, oil burners, and oil storage tanks for businesses across Liverpool, Knowsley, St Helens, Sefton, Wirral, and the wider Merseyside region.

While the majority of Merseyside's commercial sector is connected to mains gas, a significant number of businesses across the region rely on oil-fired heating systems — particularly on the Wirral peninsula, in rural and semi-rural locations on the fringes of Merseyside, in older commercial and agricultural premises where gas infrastructure has not been extended, and in specialist industrial applications where oil-fired systems remain the preferred fuel source. These systems require OFTEC registered engineers with genuine commercial and industrial oil experience.

Call us on 01772 382971 — 24/7 emergency oil heating response available across Merseyside.

Our Commercial & Industrial Oil Services Across Merseyside

Commercial & Industrial Oil Boiler Servicing & Maintenance Merseyside

We service and maintain commercial and industrial oil boilers across Merseyside covering all major manufacturers including Hamworthy, Potterton Commercial, Grant Commercial, Firebird Commercial, Worcester Bosch Commercial, Riello, Warmflow Commercial, and all leading oil boiler brands.Every service includes full oil burner inspection and strip, combustion analysis and flue gas testing, heat exchanger inspection, fuel pump and filter checks, oil line integrity testing, controls and safety device testing, and a full written service report with OFTEC documentation issued on completion. Planned preventative maintenance contracts available for Merseyside businesses requiring year-round oil boiler coverage.

Oil Burner Servicing, Repairs & Combustion Tuning Merseyside

The oil burner is the component most likely to cause breakdowns and efficiency losses in any oil-fired system. We service and repair all types of commercial and industrial oil burners across Merseyside — including pressure jet burners, rotary cup burners, and vaporising burners — covering all major manufacturers.Full burner services include nozzle replacement, electrode inspection and adjustment, photocell cleaning and testing, combustion head inspection, fuel pump pressure testing, and full combustion analysis with CO and CO2 measurement. Combustion tuning reduces fuel consumption, lowers running costs, and ensures safe, efficient operation across your oil heating plant.

Commercial Oil Boiler Repairs Merseyside

When a commercial oil boiler fails at a Wirral business, a Merseyside care home, or an off-gas-grid commercial property across the region, fast response is essential. Our engineers respond quickly to oil boiler breakdowns across Merseyside, carrying diagnostic equipment and commonly required parts to maximise the chance of a first-visit repair. We cover all major oil boiler brands and all system configurations including cascade systems and pressurised systems.

Oil Tank Installation & Replacement Merseyside

We supply and install commercial and industrial oil storage tanks across Merseyside — including single-skin steel tanks, bunded steel tanks, and bunded plastic tanks in a range of capacities from 1,000 litres upwards to large-scale industrial installations.All oil tank installations are carried out to current OFTEC and Oil Storage Regulations standards — with correct secondary containment, overfill protection, correct siting relative to boundaries and drainage, and full commissioning documentation. We also carry out oil tank replacements where existing tanks are reaching end of life, failing structurally, or no longer compliant with current regulations.The Wirral peninsula and rural fringes of Merseyside have a higher concentration of oil-fired commercial premises than the urban core — including farms and agricultural businesses, rural hotels and hospitality venues, older commercial premises, and country estates all requiring compliant oil storage installations.

Bunded Oil Tank Upgrades & Secondary Containment Merseyside

Current Oil Storage Regulations require commercial premises storing above certain thresholds to use bunded tanks or provide secondary containment. Many older commercial and agricultural properties across the Wirral, Sefton, and rural Merseyside still operate single-skin tanks that no longer meet current regulatory requirements.We assess existing oil storage installations across Merseyside, advise on compliance obligations, and carry out bunded tank upgrades and secondary containment installations to bring sites into full regulatory compliance — avoiding enforcement action and protecting against potentially costly oil spill incidents and environmental liability.

Oil Tank Decommissioning & Removal Merseyside

When oil-fired systems across Merseyside are being converted to gas, replaced with alternative fuel systems, or simply decommissioned as part of a site redevelopment, oil tanks must be safely cleaned, made inert, and removed in full compliance with current waste regulations. We carry out commercial and industrial oil tank decommissioning across Merseyside — including tank cleaning, degassing, cutting and removal, and appropriate waste disposal documentation.

Oil Pipework, Pumps & Filter Maintenance Merseyside

We maintain and repair oil pipework, oil pumps, fuel filters, de-aerators, and associated fuel supply equipment across Merseyside commercial and industrial sites. Oil pipework deterioration, pump wear, and blocked or saturated filters are among the most common causes of oil boiler breakdown and inefficiency. Regular inspection and maintenance of the complete fuel supply system is an essential part of any commercial oil maintenance programme.

Oil System Inspections & Compliance Merseyside

We carry out full commercial and industrial oil system inspections across Merseyside — covering oil storage, pipework, burners, boilers, and associated equipment. These inspections are commonly required as part of commercial property acquisitions, insurance renewals, lease renewals, farm tenancy agreements, or proactive maintenance strategies. We provide a full written compliance report and OFTEC documentation on completion.

Planned Preventative Maintenance Contracts Merseyside

The most cost-effective approach to managing commercial oil heating plant is through a planned preventative maintenance programme. AAC Gas offer tailored PPM contracts for Merseyside businesses operating oil-fired systems — scheduling regular servicing, combustion analysis, filter changes, and system checks to prevent breakdowns, extend equipment life, and maintain full OFTEC compliance throughout the year.
