Where appliances or pipework are no longer needed — ahead of a refurbishment, strip-out or change of use — ComGas safely purges, disconnects and caps redundant commercial gas installations, sequenced around your wider project programme across Surrey and surrounding counties.
When a building is being refurbished, stripped out or repurposed, gas appliances and pipework that are no longer required need to be safely taken out of service — purged, disconnected and capped so the redundant installation presents no ongoing risk. This is a specific gas-safety task, distinct from the wider refurbishment or fit-out project it usually sits within.
ComGas carries out gas decommissioning for commercial buildings across Surrey and surrounding counties, working around the sequencing of the broader project. Where the redundant installation is only part of a larger building being refurbished, we confirm exactly what is being decommissioned and what, if anything, remains in service, so nothing is disconnected in error.

Commercial gas decommissioning from Farnham, Surrey.
From a single redundant appliance to a full strip-out ahead of refurbishment, we scope decommissioning around what is actually being removed and what remains.
Safely isolating and disconnecting individual gas appliances that are no longer required, capping the supply as appropriate.
Purging and safely capping redundant sections of pipework, whether part of a wider building or an area being fully stripped out.
Decommissioning gas installations ahead of a wider refurbishment, fit-out or change-of-use project, sequenced around the main programme.
Removing part of an installation from service while confirming the remaining pipework and appliances stay safely in operation.
Planned. Professional. Practical.
Before any decommissioning work begins, we confirm exactly which appliances and pipework are being removed from service and which, if any, remain in use — particularly important where a building is only partially affected by a refurbishment. Once the scope is agreed, the affected section is purged of gas, physically disconnected and safely capped.
On completion, we confirm what has been decommissioned and, where the wider installation remains in service, that it continues to operate as expected. Documentation covering the work carried out is provided so there is a clear record for the building owner or the wider project team.
Gas decommissioning is very often one task within a larger refurbishment, strip-out or change-of-use project involving several trades. We work with the main contractor or project team to sequence decommissioning at the right point in the programme, so redundant gas installations are safely out of the way before other works proceed, without disrupting parts of the building that remain in use.
The scope, sequencing and any documentation required for a decommissioning project are agreed with you or your project team before work is programmed.

Common questions about safely removing redundant gas installations from service.
Talk to the gas decommissioning teamDecommissioning means safely purging any gas remaining in the affected pipework, physically disconnecting it, and capping the supply so the redundant installation is left in a safe condition. The exact scope is confirmed with you before work begins.
Yes. Where only part of a building is being refurbished or changed, we identify exactly which appliances and pipework are being removed from service and confirm that the remaining installation is unaffected and continues to operate normally.
Yes. We confirm what has been decommissioned and provide documentation of the work carried out, which can be passed to the building owner, the main contractor or the wider project team as required.
Yes. Decommissioning is commonly one task within a larger refurbishment or strip-out programme. We work with main contractors and other trades to sequence the work at the appropriate point, so it does not hold up or conflict with the rest of the project.
In most cases, yes — pipework being taken permanently out of service is purged of gas before it is physically disconnected and capped. See our Gas Purging page for how that stage of the process works.
Tell us what is being removed from service, whether it is part of a wider project, and any programme constraints. We can advise on how decommissioning fits around the rest of the works.
