Dial Before You Dig

Damage to gas pipes can cause leaks resulting in major disruption, fire, explosion and loss of supply.

The purpose of our ‘Dial Before You Dig’ initiative is to highlight the dangers of working in close proximity to gas pipes and to ensure that you are taking adequate precautions when digging.

At the planning stages of any works, PNG Records Department should be contacted, by calling 02890 55 5819.

If possible, please provide 10 days notice when requesting copies of gas drawings or safety information.

It is essential also that you have checked our street list of critical supply main locations.


High Risk Mains Locations

The term ‘High Risk’ refers to areas having mains operating at pressures greater or equal to 4bar, critical supply main and pressure reduction equipment sites where hazards resulting from impact or interference present increased risk to people and property. Additional precautions are therefore necessary during the execution of works near to such pipe and plant.

These items of pipe and plant will be identified on drawings supplied by PNG (Note: small service pipes to buildings are not generally shown). Additional requirements will be stipulated in our High Risk letter, which will accompany the drawings.

These requirements can be summarised as follows;

Prior to commencement, contact Phoenix Natural Gas on 028 90 55 5819 three working days in advance so that we may co-ordinate a visit to site by a member of the company’s engineering team where the following is proposed;

Excavation (drilling, moling, etc) within 3m of gas mains

Excavation (drilling, moling, etc) within 10m of pressure reduction equipment

NOTE: When the risks on site have been assessed by a Phoenix Natural Gas Engineer and control measures agreed, restrictions on proximity distances may be reduced. Phoenix Natural Gas personnel must witness excavation in the vicinity of mains operating at 7bar and above.

The following is a complete schematic showing critical supply main locations. If your planned works involve any of these locations, contact us on 028 90 55 5819 prior to any work commencing.

Installing natural gas central heating does eliminate the need for a separate hot water tank, so it is possible to free up some space where the hot press currently exists. However, it is not a requirement of installing natural gas central heating that your hot water tank is removed, so it is entirely your choice.

Homeowners installing a new central heating appliance will be required to make an application to the Builiding Control department of their local council prior to work commencing.

Once you have requested your connection to the natural gas network, it can take up to 15 working days to get a planned connection date. Your natural gas connection is installed over approximately 5 working days, which includes re-instatement on private and public property.  The final stage is the internal installation completed by your installer which (depending on the work involved) can take on average 3 working days.

Currently Phoenix Natural Gas offers a free connection to the natural gas network, worth up to £750.  Work to install your natural gas appliance, e.g. central heating or gas fire is carried out by an independent Gas Safe registered installer.  Details of these installers can be found here.

There would be more energy saving benefits to change everything at once, but we realise that family budgets may prevent this. It is possible to change over in stages, as financial considerations allow.

As with any major home improvement there will be an element of disruption, although both Phoenix Natural Gas and Gas Safe registered installation companies (registered with Phoenix Natural Gas) will aim to keep this to an absolute minimum.

The network operator provides and maintains the natural gas network.  The supplier buys gas which they then sell to consumers via the network operator’s network.  Your supplier is your first point of contact for billing queries and payment card requests.

Phoenix Natural Gas is the gas transporter and network operator.  We do not supply natural gas.  Details of gas suppliers in the greater Belfast area can be found here.

Please call your gas supplier or 03454 55 55 55 for help and advice.

We apologise for any inconvenience caused.


Phoenix Natural Gas is the network operator and not the gas supplier.  Therefore, you will need to speak to your gas supplier.  Details of suppliers can be found here.

On occasion Phoenix Natural Gas will need to carry essential maintenance on the gas meter.  We will endeavour to notify you of this to enable access to your gas appliances after the work is carried out. However, we know that this is not always convenient for consumers. 

If we have been at your property and left a no access card this will give the appropriate number to call to get your gas switched back on.  If you have any questions regarding this please contact our customer services team on 03454 55 55 55.

Natural gas is the fuel of choice for many consumers across Europe with 20 million customers in Great Britain alone. Phoenix Natural Gas continually monitors the system for safety and operates a 24-hour emergency response service, 365 days a year. All gas appliances should be correctly installed by a Gas Safe registered installation company and should be checked annually.

Natural gas is a very convenient, clean and versatile fuel. But like all fuels it must be handled wisely to ensure its safety and efficiency. If you think you smell gas, you should contact the 24-hour gas emergency service on 0800 002 001 or click here for further advice.


No. All installers who are eligible to carry out natural gas work have been registered with Gas Safe Register, which is the national watchdog for gas safety in the UK. Many of these installers will also be registered with Phoenix Natural Gas, which ensures that you can take advantage of our many offers and incentives for new customers switching to natural gas.

A number of installation companies offer a finance facility which allows you to install a new high efficiency natural gas system and spread the cost of installation over a fixed number of months.
