Commercial Oil Boiler Experts 

Commercial oil boilers require specialist knowledge, particularly where systems are older, oversized, split across multiple buildings, or have evolved over years of “patch-up work”.

Our team works on oil-fired heating systems for properties including:

• Rural hotels and inns
• Pubs and pub restaurants
• Holiday parks and holiday homes
• Schools and education sites
• Churches and village halls
• Medical centres and community buildings
• Large rural properties with multiple heating zones

Installation of Commercial Oil Boilers

If your boiler is unreliable, inefficient, or no longer meeting the demand of your business, we can design and install a replacement system tailored to your building.

Our commercial oil boiler installations can include:

• New commercial oil boiler supply and install
• Correct boiler sizing for demand and peak periods
• System upgrades to improve efficiency and reliability
• Heating controls improvements
• Pipework upgrades
• Hot water integration where required
• Plant room optimisation

We install oil heating systems with a focus on efficiency, compliance, reliability and ease of servicing.

Commercial Oil Boiler Servicing

Oil boilers should be serviced regularly to ensure:

✅ safe operation
✅ efficient fuel use
✅ reduced breakdown risk
✅ longer lifespan
✅ fewer emergency call-outs

A commercial oil boiler service typically includes:

• combustion analysis
• burner inspection and adjustments
• nozzle, filters and fuel line checks
• safety controls testing
• inspection of system components
• performance checks

Commercial Oil Boiler Repairs 

We don’t believe in replacing systems unnecessarily. If a repair is the sensible option, we’ll explain what’s needed and get you back up and running as quickly as possible.

Common commercial oil boiler faults we repair include:

• burner lockouts
• ignition failures
• oil supply issues
• control and thermostat faults
• pump issues
• pressure/flow problems
• poor combustion or soot build-up

Grant Accredited Engineers – Specialist Knowledge You Can Trust

Many commercial premises across Dorset and surrounding areas run Grant oil boilers, because they’re a trusted manufacturer for off-gas heating.

As Grant accredited engineers, we can support:

• Grant oil boiler installation
• Grant boiler servicing
• Grant boiler repairs and parts support
• efficiency improvements and system advice

This gives commercial clients extra confidence that the engineer working on their system is properly trained and experienced with the brand.

We Take On Complex Commercial Oil Boiler Projects

Not all commercial systems are simple — and many older rural sites have complicated heating layouts that require real expertise.

We regularly work on complicated oil heating systems such as:

• buildings with multiple heating zones
• older properties with irregular pipework layouts
• plant rooms with poor access or legacy equipment
• multi-building sites (hotel + annexes, holiday parks etc.)
• systems needing improved controls and load balancing
• sites requiring phased upgrades to reduce disruption

If your system has been “made to work” over time and you’re unsure what’s going on — we can survey it, diagnose it and provide a clear plan.
