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 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 arrangements from Farnham, Surrey.
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.
Assessing the heating or hot water load, existing plant, and the gas and electrical connections available before any temporary arrangement is proposed.
Specifying a temporary boiler suited to the assessed load and arranging the unit once a suitable option has been confirmed as available.
Installing and connecting the temporary boiler to the existing system, carried out by Gas Safe registered engineers.
Removing the temporary arrangement and reinstating the main system once repair or replacement work is complete.
Planned. Professional. Practical.
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.
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.
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.

A 500 kW temporary boiler installation in the adjacent car park kept heating running while the theatre’s permanent plant was isolated, removed and replaced.

Common questions about how ComGas assesses and arranges interim boiler provision.
Talk to the team about a temporary boilerNo. 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.
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.
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.
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.
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.
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.
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.
