Commercial Heating Installation in Great Dunmow
We install commercial heating systems for new projects, replacement systems and heating upgrades across Great Dunmow and nearby areas. Each installation starts with a review of the commercial property, heating demand, hot water use, access, controls and existing equipment.
A commercial heating installation needs more thought than simply replacing a boiler. The system must suit the size of the premises, the way the building is used and the demand placed on heating and hot water throughout the day. Poorly planned installation can lead to cold areas, higher running costs, difficult maintenance and avoidable repairs.
We can install and upgrade commercial boilers, heating controls, pipework, radiators, plant room equipment and hot water systems. We also advise on different types of commercial heating solutions where suitable, including underfloor heating, heat pumps, natural gas systems, LPG, oil and modern efficient boiler models.
We plan the job carefully so the work can be completed efficiently and with as little disruption as possible.

Manufacturers We Work With
We work with a range of commercial heating manufacturers, allowing us to support different types of commercial boilers, burners, warm air heaters, heating appliances and plant room equipment.
Manufacturers we work with include:
The right manufacturer and model will depend on the building, fuel type, system demand, budget, access and future maintenance needs. We will explain why a particular boiler, part or repair route is being recommended before work is carried out.
Commercial Boiler Installations
Commercial boiler installations should be carried out by fully qualified engineers with the right commercial gas expertise. A commercial boiler must be correctly selected, installed, tested and left in a condition that is practical to service and maintain in future.
We consider the size of the premises, heating and hot water demand, gas supply, flues, ventilation, controls, pipework, safe access and the condition of the wider system. This helps us recommend equipment that can meet demand without unnecessary waste or avoidable strain on the system.
Where commercial gas work is involved, it must be carried out by a Gas Safe registered engineer with the correct qualifications. Our team can work on a wide range of gas equipment, from small domestic boilers through to larger commercial appliances, and are Gas Safe registered.
If you are replacing an older boiler, we will explain whether a like-for-like replacement, system upgrade or wider plant room improvement is the most sensible option.
Heating System Upgrades
Older heating systems can become harder to maintain, more expensive to run and more likely to fail when demand is highest. If your current system needs repeated repairs, struggles to heat the building evenly or no longer supports the way the premises operates, an upgrade may be more practical than continuing to repair ageing equipment.
We can review the existing heating system and explain whether repair, partial upgrade or replacement is the better route. This may involve replacing boilers, improving heating controls, upgrading pipework, reviewing radiators, improving hot water performance or modernising plant room equipment.
Our aim is to help you make a clear decision based on safety, reliability, efficiency and long-term costs.

Commercial Boiler Servicing and Planned Maintenance
Regular servicing is one of the most important ways to maintain commercial boilers and heating systems. It helps reduce the risk of unexpected breakdowns, supports gas safety and gives businesses clearer information about the condition of their equipment.
We provide commercial boiler service visits, annual boiler service support, routine maintenance and planned servicing for commercial premises in and around Great Dunmow. Depending on the site, an annual service may be suitable, or more frequent checks may be needed for heavily used systems or buildings with essential heating and hot water demands.
During a boiler service, our engineers may inspect the boiler, burners, controls, flues, ventilation, pipework, pumps, valves, pressure, safety devices and associated plant room equipment. We check for signs of wear, poor performance, leaks, control faults and issues that could affect safe operation.
Instead of waiting for heating to fail, regular servicing gives you the chance to plan repairs, order parts, budget for upgrades and prepare the system before winter demand increases.
We also offer service contracts for customers who need ongoing support. These can be built around the equipment on site, the maintenance schedule required and the level of cover needed.
Commercial Heating Repairs and Breakdowns in Great Dunmow
If your commercial heating fails, it can quickly affect staff, customers, tenants and the normal operation of the premises. We provide commercial heating repairs and fault finding across Great Dunmow, helping businesses identify the problem and decide the most appropriate repair route.
Our engineers will inspect the system, identify the likely cause and explain the work needed before carrying out repairs. Where a repair is possible, we aim to get the heating or hot water working again efficiently. If the equipment is old, unsafe or uneconomical to keep repairing, we will explain the replacement options.
We understand that downtime can be costly. A heating fault in office blocks, hotels, schools, warehouses, restaurants or managed buildings can interrupt normal routines and affect the people using the property. Our focus is safe fault finding, clear repair advice and reliable support when heating or hot water is interrupted.
For clients with a service contract, we offer a 4-hour response to emergency call-outs, 24 hours a day, 365 days a year.

Heating Support for Commercial Premises in Great Dunmow
We support a wide range of commercial premises across Great Dunmow and the surrounding area. Every building has different heating demands, so we assess the system based on how the property is used, when heating is needed and how much disruption the business can tolerate.
We work with offices, office blocks, schools, retail units, restaurants, hotels, warehouses, industrial units, care settings, landlord-managed buildings and other commercial properties. For some clients, the priority is annual boiler service and compliance. For others, it may be urgent repairs, plant room upgrades, replacing old equipment or improving heating controls.
Commercial heating solutions need to suit the building. A warehouse may need a different approach from a hotel, and a school may have different safety, access and scheduling requirements from a retail unit. We take those details into account before recommending upgrades and changes to your existing system.
We also understand that heating and hot water can be essential to daily operation. Keeping systems maintained helps reduce avoidable problems, supports safer use and gives businesses better control over maintenance costs.
Commercial Heating Compliance and Safety
Commercial heating work must be carried out safely, especially where commercial gas, gas appliances and commercial boilers are involved. Our Gas Safe registered engineers are fully qualified for relevant commercial gas work and understand the importance of safe operation, testing and compliance.
We work on commercial gas systems, boilers, hot water equipment, controls, flues, ventilation and plant room equipment. Some of our work includes installation, servicing, repairs, testing, safety checks and clear reporting on any issues found.
Our engineers wear company uniforms, carry ID badges and provide a detailed worksheet on completion of each job. They are also CRB-checked, which means we can work in settings where children or vulnerable people may be present, including schools, care settings and other occupied commercial premises.
We follow B&ES recommended guidelines when carrying out commercial heating work, so customers receive a clear, professional service with safety, servicing and compliance properly considered.
Service Contracts for Commercial Heating
Service contracts are useful for businesses, landlords and managed premises that need planned maintenance and quicker support when heating problems occur. They help keep servicing organised, maintenance records clearer and equipment checked at suitable intervals.
A service contract can cover routine maintenance, annual service visits, planned inspections, repair recommendations and support for commercial boilers, heating controls, hot water systems and plant room equipment. The exact schedule depends on the site, the system and how heavily the equipment is used.
For clients with a service contract, we offer a 4-hour response to emergency call-outs, 24 hours a day, 365 days a year. This can be valuable for premises where heating and hot water are essential to keeping staff, tenants, customers or visitors safe and comfortable.
Service contracts can also help reduce the risk of avoidable downtime. Our regular checks allow worn parts, poor performance and small faults to be identified before they become larger problems.

Commercial Heating Great Dunmow FAQs
How often should a commercial heating system be serviced?
Most commercial heating systems should be serviced regularly, often at least once a year. Sites with heavy use, older equipment, larger plant rooms or essential heating and hot water needs may require more frequent checks. Regular servicing helps reduce the risk of sudden system failures, supports safe operation and can help extend the lifespan of boilers, pumps, valves and associated equipment.
How long does a commercial boiler service take?
A typical boiler service may take between 30 minutes and an hour, depending on the size, condition and accessibility of the boiler. Larger commercial systems, plant rooms or sites with multiple appliances may take longer, especially where additional safety checks, fault finding or maintenance work is needed.
Can upgrading an old commercial heating system reduce running costs?
Yes, in many cases. Replacing older equipment with high-efficiency models can reduce long-term operational costs, especially where the existing system is inefficient, poorly controlled or expensive to maintain. Condensing boilers are known for high energy efficiency, and modern controls can help reduce wasted heat.
What are common signs a commercial boiler needs repair?
Common signs include pressure loss, unusual noises, fault codes, leaks, poor heating performance, no hot water, repeated resets and controls not responding. If these issues keep returning, it is better to arrange an inspection before the fault causes wider disruption or leaves the premises without heating.
What should I do if my commercial heating stops working?
Check basic controls only if it is safe to do so, then contact qualified commercial heating engineers. Avoid DIY work on commercial boilers, gas systems or plant room equipment. We can inspect the system, identify the likely fault and explain the repair options. Emergency cover is especially important for commercial premises where heating or hot water failure could disrupt staff, customers, tenants or normal operations.
Can you provide planned maintenance or service contracts?
Yes. We provide planned maintenance and service contracts for commercial heating systems, commercial boilers, hot water systems and associated equipment. A maintenance contract can be built around the site, system type and servicing schedule required. Fixed pricing within a service contract can also make budgeting easier and help avoid last-minute repair decisions.
How often are gas safety checks required?
Gas safety checks are generally required every 12 months where they apply. For landlords and commercial property managers, keeping gas safety records up to date is important for compliance, insurance, tenant safety and day-to-day management of the premises.
Do commercial boilers need Gas Safe registered engineers?
Yes. Relevant gas work on commercial boilers and commercial gas appliances must be carried out by a Gas Safe registered engineer with the correct commercial qualifications. Gas Safe engineers should carry their ID cards, and you can ask to see proof before work begins. For oil heating systems, OFTEC registration may be relevant.
Do you support commercial hot water systems?
Yes. We support commercial hot water systems where they are part of the wider heating or plant room setup. This can include servicing, repairs, fault finding, pipework, controls and associated equipment.
Can you work in schools or care settings?
Yes. Our engineers are CRB-checked, which means we can work in areas where children or vulnerable people may be present. This is useful for schools, care settings and other occupied commercial premises.
Do you work with landlords and facilities managers?
Yes. We support landlords, facilities managers, property managers and commercial clients across Great Dunmow and nearby areas with servicing, repairs, installation, maintenance, service contracts and plant room support.
Are electric heating options suitable for small commercial spaces?
Energy-efficient electric heating can be suitable for some small commercial spaces, especially where gas is not practical or where heating demand is limited. Direct electric heating is efficient at the point of use, but running costs, EPC requirements, building size and usage patterns all need to be considered before choosing it.
Are air source heat pumps used in commercial heating?
Yes. Air source heat pumps can be used in commercial heating solutions, depending on the building, heating demand, insulation, available space and budget. Installation costs can be higher than some traditional systems, but they may help reduce carbon output when correctly designed and installed.
Are radiant tube heaters suitable for warehouses or workshops?
Radiant tube heaters can be a good option for workshops, warehouses and other large spaces with high ceilings. They heat people, surfaces and working areas directly, rather than trying to heat a large volume of air. Suitability depends on the building layout, usage, ventilation and installation requirements.
What type of commercial heating system is best for my premises?
The right system depends on the building, heating demand, hot water use, layout, insulation, controls and how the premises are used. A proper assessment may include room-by-room heat-loss calculations, plant room review and checks on pipework, ventilation and access. Some sites may suit modern commercial boilers, while others may need modular boilers, heat pumps, radiant heating, underfloor heating or other commercial heating solutions.
