Where more than a single hired boiler is needed to keep a building warm during a full plant replacement, extended works or an unplanned failure, ComGas can assess your site and co-ordinate a broader interim heating strategy alongside the main project. Scope and availability depend on survey and the arrangements confirmed at the time.
Interim heating, considered as a project in its own right
Some situations need more than one hired boiler.
A single temporary boiler is often enough to bridge a short gap. But where a building is undergoing a full plant replacement, a longer refurbishment, or has lost heating across multiple zones or buildings, the interim arrangement needs to be considered as a project of its own — covering distribution around the site, connection points, and how the temporary provision will be phased alongside the main works.
ComGas can assess a site facing this kind of situation, discuss what interim heating strategy may be achievable, and co-ordinate the temporary arrangement alongside a planned boiler or plant replacement project. As with a single temporary boiler, we do not operate our own hire fleet and do not guarantee stock, a fixed delivery timescale or continuity of supply — what is achievable depends on a site assessment and the arrangements confirmed at the time.

Assessment, co-ordination and phased delivery of an interim heating strategy.
For larger or longer situations than a single hired boiler can cover, we can help plan and co-ordinate the interim arrangement alongside your main project.
Site & Project Assessment
Assessing the scale of heating loss across the building or site, and how it relates to the timescale of the main boiler or plant project.
Assessment across multiple zones or buildings where relevant
The right interim approach depends on the scale of the project.
Before proposing anything, we look at how much of the building or site is affected, how long the main project is expected to take, what distribution and connection points exist, and where interim provision could realistically be sited without disrupting the main works. Where the main project is being delivered in phases, the interim heating strategy is considered alongside that phasing rather than as a single fixed arrangement.
This assessment shapes what is proposed and how it is phased. As with any interim arrangement, we explain honestly what is achievable for the specific project rather than assuming a standard solution will fit every situation.
Scale of heating loss assessed across the site
Main project timescale and phasing considered
Distribution and connection points reviewed
Practical siting options identified for interim provision
Access and safety considerations reviewed alongside the main works
Recommendation explained clearly before proceeding
A broader interim strategy still depends on what can be confirmed at the time.
As with a single temporary boiler, ComGas does not own a hire fleet and does not have an exclusive arrangement with a single hire provider. What interim heating provision can be arranged for a larger project, and how it is phased, depends on a site assessment and on the arrangements that can be confirmed once the requirement is understood. We set this out clearly so it can be planned around realistically, alongside the main project timescale.
No hire fleet is owned or guaranteed by ComGas
No single exclusive hire-partner arrangement is assumed
Interim provision confirmed by assessment, not promised in advance
Phasing agreed alongside the main project programme
Continuity depends on what has actually been arranged
Scope, specification and availability for a temporary heating solution are confirmed following a site assessment 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.

Matt from ComGas Services UK Ltd was very professional, polite, friendly and quick installing a new shower in my bath (and at a better height for me) and a much easier press-in plug for my sink! He left the place spotless. This is the kind of service and installation people dream about - a 5 star service (see photos).

I have used Comgas twice and both times have been very happy with the service. Very friendly and honest. The most recent time, the job turned out to be a lot bigger than they initially thought but it was no issue and Paul stayed the extra time to make sure the job was done properly! He was really tidy, took a lot of care with the work that was done and took the time to explain what he was doing and why. Pleased to have found a reliable heating company!

I had an issue with my boiler and Matt came out to have a look the same day and managed to fix it. Great, professional service. Highly recommend.

First time we've used this company and it won't be the last. Very professional and efficient in everything they do and Matt was excellent in his knowledge and efficiency when dealing with our gas and plumbing problems.

Fantastic experience from the chaps at ComGas! Special thanks to Matt who removed an old boiler and replaced with a new energy efficient to satisfy the demands of a five bed house with a few bathrooms/baths and showers. The ComGas admin team and Lee were fantastic too on the booking and administration side of things!

Here at St Joseph's we have worked with Comgas for a number of years. They have completed big projects and undertake regular maintenance for our school. They price fairly, and their work is completed to a very high standard. All the engineers carry a DBS which makes life so much easier when trying to book an engineer visit.
On the rare occasion that we have an emergency I can trust that Lee will get one of his engineers to respond quickly and efficiently.
Nothing is too much trouble and no job is too small.

Temporary heating solutions FAQs
Questions about interim commercial heating strategies
Common questions about how ComGas assesses and co-ordinates broader interim heating provision.
How is this different from a single temporary boiler?
A single temporary boiler, covered on our Temporary Boiler Hire page, suits a straightforward gap in provision. This page covers a broader interim heating strategy — needed where more of the building or site is affected, or where the interim arrangement needs to be phased alongside a longer plant replacement project.
Can you provide interim heating across multiple zones or buildings?
We can assess the scale of heating loss across a site and discuss what interim strategy may be achievable, including how any provision would be distributed. What can actually be arranged depends on the site assessment and the connections and access available.
Do you guarantee a fixed timescale for interim heating provision?
No. As with a single temporary boiler, we do not promise a fixed delivery or continuity guarantee in advance. What is achievable, and how it can be phased, is confirmed once we have assessed your site and the wider project timescale.
Can interim heating be phased alongside a plant replacement project?
Yes. Where a main boiler or plant replacement project is being delivered in stages, the interim heating strategy is planned alongside that phasing, rather than treated as a single fixed arrangement for the whole project duration.
What happens once the main heating project is complete?
The interim arrangement is removed and normal operation is handed back to the permanent installation, co-ordinated with the team delivering the main boiler or plant replacement project.
Planning a plant replacement or facing widespread heating loss across a site?
Tell us about the building, the scale of the heating requirement and the timescale for the main project. We can arrange a site assessment and discuss what interim strategy may be achievable.
