Commercial Gas Engineers in Birmingham

Who uses our services in Birmingham?

Manufacturers and engineering firms

Tyseley, Witton, Aston, Minworth and Kings Norton are home to metal finishers, heat treatment shops, foundries and food producers. Many run process burners, ovens and space heaters from pipework that has been extended several times over the years. It is common to find several generations of steel pipe in one building, with few drawings to explain it.

When a line is altered, or a new machine is added, the affected pipework needs a tightness test and a purge before it goes back into use.

Jewellery Quarter workshops

The Jewellery Quarter has hundreds of small workshops in converted Victorian buildings. Bench torches, casting equipment and small furnaces are often fed from shared supplies that run through several units.

Isolation, labelling and testing need care in these buildings, because one riser may serve more than one business.

Restaurants and food businesses

From the Balti Triangle in Sparkbrook and Balsall Heath to the city centre and the wholesale markets in Witton, commercial kitchens need safe pipework, working interlocks and current paperwork. We carry out commercial catering installation and testing as well as gas safety certificates.

Hospitals, universities and large venues

The hospital and university campuses in Edgbaston and Selly Oak, along with the exhibition and airport sites towards Solihull, run large boiler houses with long site mains. These are usually tested in sections during planned shutdowns.

Construction and fit-out contractors

With major regeneration under way in Birmingham around Digbeth, Curzon Street and Smithfield, contractors need new gas installations tested, purged and commissioned before handover. We work to your programme and provide the records your client will ask for.

Tightness testing, purging and commissioning explained

A tightness test proves that pipework does not leak at its working pressure. New pipework also has a strength test at a higher pressure before it is connected to a live supply.

Purging follows. When a system is being commissioned, air is removed from the pipe and replaced with gas. When a system is being decommissioned, gas is removed and replaced with air or an inert gas.

On larger pipework, nitrogen purging is used as a buffer so that gas and air do not mix inside the pipe. The purge is vented to a safe point outdoors and monitored with a gas detector until the readings are correct.

This work is carried out to IGEM/UP/1, or to IGEM/UP/1A on smaller low pressure installations. New commercial gas pipework is installed to IGEM/UP/2.

What should you think about before work starts?

Is the site inside the Clean Air Zone?

The Clean Air Zone covers the roads inside the A4540 Middleway ring road. It is worth allowing for this when planning deliveries of pipe, plant and welfare units to city centre sites.

Does the job involve digging in the road?

Birmingham City Council is the highway authority for local roads. If a new supply route or an underground pipework run crosses a public footway or carriageway, a street works permit or a section 50 licence will normally be needed from the council before excavation starts.

National Highways is responsible for the M6, M5 and M42 and their junctions. Work on private land does not need a highway permit, although a buried services search should always come first.

Sites beside the canal network may also need to speak to the Canal and River Trust if work affects the towpath or a canal wall.

Who owns which part of the supply?

The local gas network is operated by Cadent. Cadent owns the service pipe up to the emergency control valve, and the meter belongs to your supplier or meter operator.

If you need a bigger supply or a new connection, that request goes to Cadent or to a registered utility infrastructure provider. Everything after the meter is the site owner's responsibility, and it is this pipework that we install, test and maintain.

Can the work be done out of hours?

Many Birmingham factories only have short shutdown windows, often at weekends or during the summer and Christmas breaks. Our team works seven days a week, so testing and purging can be planned around production.

Repairs and leak investigation

A smell of gas should always be reported to the National Gas Emergency Service on 0800 111 999. Their engineer will make the site safe, which often means isolating the supply at the meter.

Finding and fixing the fault on your own pipework is then down to you. We carry out leak investigation and emergency gas repairs, followed by a tightness test and purge so the supply can be restored.

Decommissioning old pipework

Older industrial units often contain redundant gas lines from previous tenants. These should not simply be left in place. A capped pipe that is still connected to a live supply can be damaged during later building work, and nobody on site may know it contains gas.

Decommissioning means purging the gas out, cutting the pipe back to a suitable point, capping it and recording what has been done. This is particularly important before demolition, change of use or a move to electric plant.

Coverage across the West Midlands

We work in all Birmingham postcode districts, from B1 in the city centre out to Northfield, Longbridge, Erdington and Castle Vale.

Gas Main Installation also covers the towns and boroughs around the city. This includes Solihull in B90 to B94, Sutton Coldfield in B72 to B76, West Bromwich, Smethwick, Oldbury, Halesowen, Dudley and Walsall. Further out, we work in Redditch, Bromsgrove, Tamworth and Lichfield.

Our service is available across the UK, so businesses based in Birmingham with sites in other regions can use one team for all of them.
