Every gas connection we deliver meets the highest industry standards. Worker safety, public safety, environmental responsibility, and project compliance from planning to sign-off.
Commercial and industrial gas connections across all pressure tiers. From load assessment and bespoke GDN application to pressure regulation, metering, and adoption.
Every commercial gas connection follows a clear, auditable sequence. Here is exactly what happens at each stage.
Accurate peak demand assessment is the foundation of every commercial gas connection. USP prepares a full load schedule that records the rated input of every gas-fired appliance on site: boilers, catering equipment, process plant, space heating, hot water, and any standby loads. Demand diversity factors are applied where appropriate. The resulting peak demand figure, expressed in cubic metres per hour, determines the pressure tier required, the meter capacity needed, and whether the existing GDN network can support the load without reinforcement. Getting this right at the outset avoids abortive design work and costly programme delays.
Commercial gas applications above 73,200 kWh per annum fall outside the standard domestic allowance and require a bespoke quotation from the GDN. This involves a full network analysis to assess whether the existing main has sufficient capacity, whether an extension is needed, and whether any upstream reinforcement is required. USP prepares and submits the formal application, liaises with the GDN throughout the quotation process, and advises on whether the offer represents fair value. For MP and IP connections, additional design work covers the new pressure regulation assembly and any contestable pipework upstream of the meter.
For MP and IP connections, a pressure regulating assembly (PRA) or governor installation is required on site to reduce network pressure to the appliance operating pressure. USP designs the regulation scheme, specifies the appropriate governor or pressure regulating equipment, and manages the contestable installation works. The non-contestable tapping and live main connection is carried out by the GDN under a separate programme. USP coordinates both elements to avoid gaps in the programme. All pipework is installed, jointed, and pressure tested in accordance with the relevant IGE/TD standards.
Commercial gas meters are specified to match the peak demand calculated in the load schedule. For sites above 73,500 kWh per year, half-hourly AMR or SMETS2 smart metering equipment is mandatory. USP specifies the meter index, selects the appropriate AMR communications technology, and coordinates installation with the gas shipper and meter operator. The GDN formally adopts the connection infrastructure and issues the Meter Point Reference Number (MPRN), which is required before a gas supplier can activate the supply. USP tracks this process to ensure the MPRN is in place when commissioning is due.

I contacted USP and within minutes had a chat with Justin who described exactly how the job would be done and provided a comprehensive quote including labour and materials and was able to start the work in just 7 days. Justin and his team were brilliant and did an amazing job. I can highly recommend USP.
Jack and Joel were absolutely amazing this morning and really put themselves out to dig a hole without having to dig another hole in my drive. More work for them but one happy customer.
From the initial quote through to work completion, Justin and his work partner were a mix of professional, knowledgeable, good-humoured, and clear in all explained (I felt an instant ease to agree to the work). The work itself was excellent and they left the place immaculate!
George and Jack come out today to move a gas meter. It wasn't a straightforward job, but they both took time to talk me through what they were doing and what the next steps are. Very friendly and polite and thought about the needs of our family.
Jack and George are great.
Bang on time, completed the work perfectly, no issues. Left the meter really neatly finished. Jack and Joel were very courteous and did a great job.
George and Jack turned up and did a first class job, very friendly and professional. Great job lads.
Jack and Joel were brilliant. Very polite, worked to my highest expectations. Left the area as clean and tidy, as was possible. And explained every step of the process to me, answering any questions I had.
Fantastic work from Jack and Johl.
