Introduction & Process

We will be installing the gas distribution infrastructure to ensure the new supplies you have requested are installed/commissioned to the required metering points. Once this infrastructure has been commissioned it will then become fully owned and maintained by the adopting Network Operator.

An approved design will be provided for you which will have been validated by the adopting Network Operator. It is essential that the elements of the installation that you are responsible for are

installed to the exact specification required on the design, failure to adhere to this could result in the commissioning of the new infrastructure being delayed and/or incurring additional costs, something we are very keen to avoid.

Finally, if there is any part of this project that you are unsure, unhappy or really pleased about, please don’t hesitate to contact us. In addition, we will also provide you with details of our Area Construction Manager should you wish to escalate any queries.

UK Power Solutions aim to provide the highest standard of customer service throughout the entire connection process providing the customer with a single point of contact at every stage of the project.

Smell Gas? To report a gas or carbon monoxide emergency, or if a pipeline is struck (even if no gas leak has occurred) call the National Gas Emergency Service 24 hours a day on 0800 111 999.

Service positions and routes

PositionsThe position of the meter must be on the wall of the property facing the parent main, or, where it is required, on the side of the property no more than 2m down the gable. Meters cannot be installed to the rear of the property.

If you feel you cannot achieve the requirements, please contact your Project Manager.

RoutesThe service pipe must not be installed in any land other than that of the property it is supplying or public/shared driveway. Where a service is required to cross the road to a main on the opposite footpath, it must be laid in an individual road crossing (it is acceptable to install ducts for these road crossings as required). We will try to minimise this as much as possible during the design stage.

Examples of serviceroutes where roadcrossings required.

Note: Drawings are NOTto Scale

Service Positions

All services must be laid individually and perpendicular to the building takingthe shortest route practicable to the main unless otherwise indicated on theapproved construction drawing.

The position of the meter must be on the front of the property or where it isrequired on the side of the property must be no more than 2m from the frontgable end.

Where a service is required to cross the road to a main on the oppositefootpath it must be laid an individual road crossing. We will try and minimisethis as much as possible during the design stage. If you feel you cannotachieve the requirements, please contact your Project Manager.

General Advice

Sealing of outlets

The meter installer will fit the meter and label accordingly. It is your responsibility to ensure that the meter box outlet spigot or any through-wall sleeve carrying the meter outlet pipework is correctly sealed to prevent the passage of gas into the property.

Failure to do this is a breach of the Gas Safety (Installation and Use) Regulations.

Handling of Pipe

Mains pipe may be delivered to site in coils or straight lengths. Individual smaller coils are generally capable of being handled manually. However, larger coils will require mechanical lifting using soft straps.

The handling of straight pipe lengths requires some expertise, especially once any pipe packs have been unbound.

UK Power Solutions will move individual mains pipe lengths from the storage point to the construction location.

Electrical Cross Bonding

An electrical cross bonding wire (where required) should be connected to the gas meter outlet in accordance with IEE Regulations. When the bonding wire enters a built-in box from the rear it must pass through the outlet installation pipe spigot and be contained within the seal.

The box must not be broken to accommodate the bonding wire.

Please remember that you are not permitted to lay any gas pipe. This must be done by one of our qualified installers.

General Advice (cont.)

Ducts

Yellow perforated rigid plastic ducting (complying with BS4962) can be used for perpendicular road crossings only and will be discussed at your pre-start meeting.

It is your responsibility to supply ducts and install to the correct specification (ensuring minimum depth is achieved) otherwise we may not be able to lay pipe through incorrectly laid ducts.

Gas marker tape must be laid at least 250mm above mains ducts & 150mm above service ducts.
