Commercial gas meter disconnection

Do I need a commercial gas meter disconnection?
The reasons for requiring a gas meter to be disconnected from the mains are many, for example if your site is being refurbished, if you need to the move the meter to a different place, or even the demolition of your property. Whatever the case, you will need to call upon a qualified gas metering expert to carry out the works as safely as possible. Our experienced team can help you assess your situation and identify the requirements of your gas meter disconnection, as well as advising on additional work that may be needed as part of the disconnection and removal process.

The cost of a commercial gas meter disconnection will vary, depending on circumstance. Besides offering expert advice and a cost-effective service, at SMS we also pride ourselves on the highest of safety standards as well as the efficiency of our works – ensuring that there is little or no disruption to your operations as a result of your gas meter disconnection. Before any disconnection or part/full removal of a meter can be carried out, we will need to undergo a thorough site investigation in order to identify the nature of works you require.

Remember, a disconnected meter may still be subject to meter rental charges if it is not removed and decommissioned. At SMS we also offer a service to remove your unused meters, saving you on meter rental charges that you might still incur (even though there is no longer any consumption associated).

Commercial gas meter removal

Do I need to remove my commercial gas meter?
You may want to remove your gas meter for differing reasons. For example, if your gas supply is no longer required, or if you want to upgrade or downgrade your gas meter. However, if you need to have your commercial gas meter removed, then it needs to be carried out by a qualified gas meter professional. This can be arranged through a gas connections expert like SMS.

How much does a commercial gas meter removal cost?
The cost of removing a commercial gas meter varies, depending on the type of the meter and other conditions. In order to arrange the removal of your commercial gas meter and receive an accurate quote, you will need to know both the size of the meter and the pressure tier.

Commercial gas meter upgrade

Do I need to upgrade my commercial gas meter?
Under the government mandated non-domestic smart meter rollout, all energy suppliers must offer to exchange their customers’ old gas meters to smart by 2020 (you can contact your supplier if they have not asked you about this already). If we are your supplier’s preferred smart meter installer, we will we offer you the opportunity to upgrade your gas service installation at the same time, with additional features added to bolster resilience (subject to network approval).

However, whether you have already switched to a smart meter or not, if your gas service was installed a long time ago, or if you have recently added new gas appliances to your business, then your gas supply and meter could be due for an upgrade.  If this is the case, or you are not sure, contact a gas connections expert like SMS. By confirming the size of your meter, your gas consumption (in kWh), and checking the gas pipework, we will be able to confirm whether you need an upgrade (or a downgrade if your capacity needs have decreased).

How much does a commercial gas meter upgrade cost?
The cost of upgrading your gas meter and/or gas service depends on the size of your gas meter, consumption, and whether your installation requires rerouting or new meter housing. At SMS, we offer a cost-effective solution for your upgrade needs, and will include the cost of the removal of your old meter and new installation in our quote for you.
