AAC Gas provide specialist commercial and industrial oil services across Manchester and Greater Manchester. 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 the city and surrounding areas.
While the majority of Manchester's commercial sector runs on mains gas, a significant number of businesses — particularly on the outskirts of Greater Manchester, rural industrial sites, older commercial premises, and specialist manufacturing facilities — rely on oil-fired heating systems. These systems require specialist engineers with OFTEC registration and genuine commercial oil experience, not domestic oil engineers stretched beyond their competence.
AAC Gas engineers have extensive hands-on experience with high-output commercial and industrial oil systems across all sectors. Whether you need routine annual servicing, emergency breakdown cover, an oil tank installation, or a full planned maintenance contract, call us on 01772 382971 — 24/7 emergency response available across Greater Manchester.

We service and maintain commercial and industrial oil boilers across Manchester and Greater Manchester — covering all major manufacturers including Hamworthy, Potterton Commercial, Grant, Firebird, Worcester Bosch Commercial, Riello, and all other leading oil boiler brands.Every service includes a 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 full written service report. We issue OFTEC documentation on completion and can set up planned preventative maintenance contracts tailored to your site requirements.
The oil burner is the heart of any oil-fired heating system — and the component most likely to cause breakdowns or efficiency losses when not properly maintained. We service and repair all types of commercial and industrial oil burners across Manchester, including pressure jet burners, rotary cup burners, and vaporising burners.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. Burner combustion tuning reduces fuel consumption and ensures safe, efficient operation across your heating plant.
When a commercial oil boiler fails, the impact on a Manchester business can be immediate — cold premises, lost production, disrupted operations, or a care home without heating and hot water. Our engineers respond fast to oil boiler breakdowns across Greater Manchester, 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.
We supply and install commercial and industrial oil storage tanks across Manchester and Greater Manchester — including single-skin steel tanks, bunded steel tanks, and bunded plastic tanks in a range of capacities from 1,000 litres 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 drains, and full commissioning documentation. We also carry out oil tank replacements where existing tanks are reaching end of life, failing, or no longer compliant with current regulations.
Current oil storage regulations require commercial premises above certain storage thresholds to use bunded tanks or provide secondary containment. Many older commercial and industrial sites across Greater Manchester still operate single-skin tanks that no longer meet current requirements.We assess existing oil storage installations across Manchester, advise on compliance requirements, and carry out bunded tank upgrades and secondary containment installations to bring sites into full regulatory compliance — avoiding the risk of enforcement action and protecting against costly oil spill incidents.
When oil-fired systems are being converted to gas, replaced, or decommissioned, oil tanks must be safely cleaned, made inert, and removed in compliance with current waste regulations. We carry out commercial and industrial oil tank decommissioning across Manchester — including tank cleaning, degassing, cutting and removal, and appropriate waste disposal documentation.
We maintain and repair oil pipework, oil pumps, fuel filters, de-aerators, and associated fuel supply equipment across Manchester commercial and industrial sites. Oil pipework deterioration, pump wear, and blocked or saturated filters are common causes of oil boiler breakdown and inefficiency. Regular inspection and maintenance of the fuel supply system is an essential part of any commercial oil maintenance programme.
We carry out full commercial and industrial oil system inspections across Manchester — covering oil storage, pipework, burners, boilers, and associated equipment. These inspections are often required as part of building acquisitions, insurance renewals, lease renewals, or proactive maintenance strategies. We provide a full written compliance report and OFTEC documentation on completion.
The most cost-effective way to manage commercial oil heating plant is through a planned preventative maintenance programme. AAC Gas offer tailored PPM contracts for Manchester businesses operating oil-fired systems — scheduling regular servicing, combustion analysis, filter changes, and system checks to prevent breakdowns, extend equipment life, and maintain full regulatory compliance.
Commercial oil heating emergencies require an engineer with genuine oil system experience — not a gas engineer attempting to work on unfamiliar equipment. Our OFTEC registered engineers are available 24 hours a day, 7 days a week for emergency commercial and industrial oil call-outs across Manchester and Greater Manchester. Call 01772 382971 at any time.
