When a commercial boiler fails, or planned works mean the main plant is out of action, ComGas can assess your site and arrange a suitable temporary boiler to maintain heating or hot water in the meantime. Scope and availability depend on a site survey and the arrangements confirmed at the time.
A temporary boiler still has to be the right one for your building.
A boiler breakdown or a planned plant replacement can leave a commercial building without heating or hot water for longer than is workable — particularly where the site is occupied, operational, or houses vulnerable people. In that situation, a temporary boiler arrangement can bridge the gap while the main plant is repaired or replaced. Getting this right still depends on assessing the building properly: the heating or hot water load involved, the gas and electrical connections available, where a temporary unit could practically be sited, and how it would be connected into the existing system.
ComGas can assess your site, specify an appropriate temporary boiler arrangement for the load and connections involved, and arrange for it to be installed and connected by our Gas Safe registered engineers. We do not operate our own hire fleet and do not guarantee stock availability or a fixed delivery timescale in advance of that assessment — what can be arranged, and how quickly, depends on the specifics of your site and on the arrangements available at the time. We are upfront about this so you can plan around it.

Temporary boiler hire services
Assessment, specification, installation and co-ordination of an interim arrangement.
From an initial site assessment through to installation and eventual removal once the main plant is back in service, we can support the process end to end.
Site Assessment
Assessing the heating or hot water load, existing plant, and the gas and electrical connections available before any temporary arrangement is proposed.
The right temporary boiler depends on your specific building.
Before recommending anything, we look at the actual heating or hot water demand the temporary arrangement needs to cover, the condition and layout of the existing pipework and connections, the gas and electrical supply available, and where a unit could realistically be sited — inside a plant room, in an external compound, or elsewhere on site.
This assessment shapes what we propose and how quickly it can realistically be arranged. We would rather explain honestly what is achievable for your specific site than promise a standard solution that may not fit the building or the connections available.
Heating and hot water load assessed for the affected building
Existing pipework, connections and isolation points reviewed
Gas and electrical supply checked against likely requirements
Practical siting options identified on site
Any access or planning constraints considered
Recommendation explained clearly before proceeding
We do not promise what we cannot confirm in advance.
ComGas does not own a hire fleet and does not have an exclusive arrangement with a single hire provider. What can be arranged, the specification available, and how quickly it can be installed all depend on a site assessment and on the arrangements that can be confirmed at the time you need them. We explain this clearly at the outset so you can plan realistically around it, rather than assuming a standard turnaround that may not be achievable for your situation.
No hire fleet is owned or guaranteed by ComGas
No single exclusive hire-partner arrangement is assumed
Specification and stock availability confirmed by assessment
Delivery and installation timescale confirmed once arranged, not promised in advance
Continuity of the arrangement depends on what has actually been agreed
Scope, specification and availability for a temporary boiler arrangement are confirmed following a site survey and depend on what can be arranged at the time. No delivery timescale, stock level or continuity of supply is guaranteed in advance of that assessment.

Incredible service — problems fixed perfectly once again.
Lee, Paul and the team at COMGAS are fantastic. They arrived on time and got straight to work, quickly identifying the root cause of the plumbing and heating issues I was experiencing.
The problems were diagnosed swiftly, I was kept fully informed throughout, and both issues were fixed with impressive speed and precision.
Having worked in the industry for nearly 20 years, I know how rare it is to find reliable, trustworthy, and genuinely skilled professionals — let alone a team this good.
I joked about it at the time, but it’s true: I had the best shower I’ve ever had in this house after they finished the job — and I’ve lived here for 10 years!
I honestly couldn’t ask for more and can’t recommend COMGAS highly enough.

Lee came out to the school I work in to look at a problem with our heating, he diagnosed the issue and was able to fix it on the spot in a neat and tidy manor. Would highly recommend

I recently used Comgas for a gas and heating service, and I couldn't be more impressed! From start to finish, their team was professional, friendly, and highly knowledgeable. They quickly identified the issue with my heating system and explained everything in detail, offering both short- and long-term solutions.
The technician was punctual and took extra care to ensure everything was running smoothly. I really appreciated their attention to detail and how they made sure to clean up after the work was completed. My home is now warm and cozy, all thanks to their expert service. I highly recommend Comgas for anyone looking for reliable, efficient, and trustworthy gas and heating professionals!

Temporary boiler hire FAQs
Questions about temporary boiler arrangements
Common questions about how ComGas assesses and arranges interim boiler provision.
No. ComGas does not operate its own hire fleet and does not have an exclusive arrangement with a single hire supplier. We assess your site, specify a suitable arrangement and help organise it, but availability depends on what can be confirmed at the time.
How quickly can a temporary boiler be arranged?
This depends on the specification required, what is available at the time, and the connections and access at your site. We do not promise a fixed delivery or installation timescale in advance of assessing the situation — we explain what is realistically achievable once we understand the requirement.
What size or type of temporary boiler will I need?
This depends on the heating or hot water load the temporary arrangement needs to cover, and the gas and electrical connections available at your site. We assess this before proposing a specification rather than offering a single standard option.
Can you connect a temporary boiler to our existing system?
Yes. Installation and connection into the existing heating or hot water system is carried out by our Gas Safe registered engineers, based on the assessment of your existing pipework and plant.
What happens once our main boiler is repaired or replaced?
We remove the temporary arrangement and reinstate normal operation of the main system, co-ordinated with any related repair or replacement work being carried out. See our Temporary Heating Solutions page for broader interim heating co-ordination on larger projects.
Is a temporary boiler suitable for a care setting or occupied building?
Temporary arrangements can be considered for care, residential, education and other occupied settings, but each situation is assessed on its own terms — including any specific safety, access or continuity considerations for the building. Tell us about your site and we can advise honestly on what is achievable.
Facing a boiler breakdown or planning works that will take your main plant offline?
Tell us about the building, the heating or hot water load involved and the timescale you are working to. We can arrange a site assessment and explain what may be achievable.
