Frequently Asked Questions.
How long does it take to get a quotation from E. L. Gas Connections?
It will normally take around two to three weeks to provide you with a commercial connection quotation; some domestic quotes can be provided the same days. We use our knowledge and experience of the connections market place to obtain the most compeitive costs. We do this by sourcing the lowest costs for your type of project, from a number of different connection provider companies where possible, taking into account the geographical location of the job. Not all connection provider companies work in all areas of the UK.
How much will it cost?
Quotations are issued free of charge. With regard to the cost of any works, there are so many factors affecting this that it is not possible to be specific; proximity to the nearest gas main, the amount of gas required and any known engineering difficulties being just a few. As a rough guide however, a one-off domestic connection could cost as little as a few hundred pounds, while a small commercial supply may typically cost around £3-4,000 + VAT, depending on length.
How do I find out how much gas I'm going to need?
Gas pipes and gas meters are sized in relation to the maximum amount of gas that will be needed in any one hour. For a domestic property, the gas requirement will normally be fairly standard. For commercial properties, the hourly gas requirement is variable and will depend on the number, size and type of appliances that will be fitted. The Gas Safe installer that will be connecting your appliances or the company that is supplying them will usually be the best people to contact. Simply put, the hourly gas load of a commercial property is normally arrived at by adding together the gas input ratings of all appliances to be connected, as if they were all full on at the same time.
Wouldn't it be cheaper to just go to a gas supplier for my connection?
No, absolutely not. Gas suppliers do not carry out connections work themselves and will instead, usually go to only one connections provider for a quotation. They don't install meters either so they will simply use their preferred provider and charge accordingly. Worst of all, they will require you to sign-up to a contract to purchase gas from them, as a condition of providing the connection quotation; so you may not obtain the best deal for your connection or the gas that you use and you may pay far more overall.
Are there any ventilation requirements that I need to consider when thinking about possible meter positions?
There are specific ventilation requirements for meters located inside buildings that are sized U16 and greater. We recommend that you or your consultant should obtain and follow the appropriate guidance document.
The following notes detail ventilation requirements as outlined by the Institute of Gas Engineers & Managers (IGEM) in the metering guide IGEM/GM/6 Edition 2 - Non-domestic low pressure meter installations. Standard designs, where the flow rate exceeds 6m3/hr (U16 Diaphragm meter or larger). Please be aware that the following notes are provided for information purposes only and without warranty, you should always refer to the current version of the complete document before undertaking any measures.
The purpose of ventilation in a meter installation housing is to;
- Ensure that minor gas leakage does not cause the atmosphere within the housing to become unsafe
- Allows any escape of gas to be smelled or otherwise detected by passers-by
- Reduces condensation
The total effective ventilation area (free area) shall not be less than 2% of the internal floor area of the housing or its notional equivalent and should be equally distributed and disposed at high and low levels around the outside walls.
The notional equivalent floor area is the floor area of an imaginary housing to enclose a meter installation which is, in fact, located in a larger open area such as workshop, boiler house or other part of a building. Where only one wall is used, ventilation must be increased to at least 3% of the notional floor area.
Low level ventilators should be positioned 150mm above the floor. The high level openings should be situated as close as possible below, but not more than 10% of the total height below, the roof or ceiling level. Where housings have an apex roof design, the level of ventilation should be achieved by utilising ridge ventilators. Any ceiling shall not create an unventilated void.
- A ventilator shall not be located near any air in-take duct so as to avoid escaping gas re-entering the building
- Ventilation opening shall not be into a hazardous area, e.g. into area where welding or other such activities take place
- Ventilators shall be non-adjustable and should be weather proof and fire resistant
- Ventilators should be designed to prevent the ingress of rain and blockage by leaves and snow
- Holes for the fixing of ventilators shall be fully sealed and designed to ensure that any inner core material will not be exposed to moisture ingress
- The openings in the ventilator shall not be such that a 9.5mm sphere cannot pass through
- If the high level ventilator is in the form of a gap(s) between the walls and the roof of the housing, such a gap shall not exceed 9.5mm
- Should the meter location fail to comply with the above requirements the service may not be installed.
