Utility connection application

A utility connection application goes to the network operator that owns the cables, pipes or mains at your postcode: this tool names the operator, the form and the statutory timescale for electricity, gas and water, for your job type.

Routes verified against each operator's published process, August 2026

Step 1 of 6: Utility

Which utility is the application for?

Pick one and we take you to that utility's page, where the operators, the forms and the timescales are its own. A site that needs more than one runs the tool once per utility.

Which operator, which form, and what the law says about the wait

There is no single national connection form for any utility. The company that owns the network at your postcode publishes its own application routes: one of six electricity distribution network operators across fourteen licence areas, one of four gas distribution networks across thirteen local distribution zones, or the water wholesaler appointed for the area. Most of them split small and large jobs at a threshold of their own. The tool above works out the operator from the postcode, or exactly from the meter identifier where the site already has one, and names the route for the job.

The first question is always who the application goes to. A new connection, more or less capacity, a move of the supply position, a diversion of the network's own assets or a permanent disconnection is the network operator's job. Removing a meter, moving it without touching the incoming cable or pipe, and switching a supply off and on for works belong to your supplier, because the supplier owns the meter. On water the same split runs between the wholesaler and the retailer. Sending a meter request to the network, or a capacity application to the supplier, costs weeks, so the tool checks the party before it names the form.

The second question is the wait. An electricity connection application runs on the quotation periods in the Electricity (Standards of Performance) Regulations 2015, in working days from a complete application; a gas connection application on the Gas (Standards of Performance) Regulations 2005. Water has no equivalent statutory quotation period: a water connection application runs on the wholesaler's own published levels of service. Each utility page carries its own routing table, statutory rows and questions.

If you only need the identity of the operator rather than the application, the network operator lookup answers that in one search, and the new energy connections guide sets out the whole process from capacity scoping to energisation, with the costs in our guide to new connection costs. When the connection is live, the supply contract on the new meter is a separate decision: request a business energy quote and we tender it across 30+ suppliers so the site never sits on a deemed rate.

Statutory quotation timescales

Working days from a complete application, set by regulation rather than by the operator. Electricity and gas have them; water does not.

Water

There is no statutory quotation period for water connections in the instruments we cite. The wholesaler's own developer-services levels of service apply. Published levels were read for 14 of the 18 wholesalers listed in the routing table below and appear under each; where none were read, the result card says so and we confirm them with the wholesaler.

Working days from a complete application. Which standard applies to a job is the operator's determination; the result card highlights the row its reading of your answer points to.

Application routes by network operator

Every electricity licence area, gas distribution zone and water wholesaler, grouped by operator, with the routes, contacts and timescales each operator publishes. 61 operators in the registry. Routes verified against each operator's published process, August 2026.

Electricity: the 14 distribution licence areas

The two-digit code is the distributor id at the start of a 13-digit MPAN core. An id of 24 or above is an independent distribution network operator, listed in the next section.

  • Every www.ukpowernetworks.co.uk URL is unverified as to content; only the media.umbraco.io PDFs were read.
  • Under 70kVA versus over 70kVA is the primary routing decision: different teams, phone numbers, emails and mechanisms. Ask for expected capacity before routing.
  • Meter removal is the supplier's job. UKPN's Disconnections team removes the service and closes the MPAN only after the supplier has removed the meter.
  • The January 2023 over-70kVA form (UKPN14421) is still live at a 200 URL but superseded by the May 2026 v4; the 'uk-power-networks' Umbraco bucket is dead. Re-verify any UKPN PDF URL against the ukpn-cms bucket.

Electricity: transmission connections

Connections at transmission voltage go through the system operator with the host transmission owner. No application form: a hand-off to Purely's procurement team.

  • Transmission connections are a hand-off: the wizard shows an explanation card and routes to the procurement team, never a form.
  • The wizard needs an MVA or export-MW input to trigger this hand-off; demand customers at distribution voltage whose load affects the transmission system go through their DNO's Statement of Works, not to NESO.
  • Meter relocation and meter removal have no NESO route: transmission metering sits under the BSC and the bilateral agreement. There is no temporary builder's supply at transmission level.
  • The legacy application forms workbook still carries a 2022 Warwick address, phone numbers and a nationalgrideso.com mailbox; none are published here.
  • The 'meter relocation or diversion' entry in the research (Exhibit I 'Change of Connection Site') is an interpretation, not a NESO service, and is not carried as a route.
  • Ofgem approved the connections reform package on 15 April 2025 (CMP434 and CMP435 implemented 10 June 2025); Gate 2 Phase 1 offers run mid-May to mid-September 2026 and Phase 2 early September 2026 to mid-January 2027. Re-check the window status weekly.

  • Capacity reduction is not a consumer-facing product; the business rules define 'Capacity Increase / Decrease' as an alteration, and a Supply Offtake Quantity change is a shipper matter.
  • The 3,912 pounds figure is the standard domestic charge and only applies where the domestic eligibility criteria are met; a small business connection is quoted.
  • Older documents remain live and mislead: April 2020 standard charges, the 2016 methodology and the May 2024 4B statement are superseded; a 2016 leaflet points at a dead onlinequote short URL.
  • Connections terms are inside the quotation pack rather than a standalone document, so no termsUrl is recorded.
  • Gas guaranteed standards GS4 to GS10 appear in the Notice of Rights and Business Rules; they are the statutory regime listed once in STATUTORY_STANDARDS.

  • A postcode lookup always returns the host GDN and silently misroutes an iGT-connected site: on an existing meter route on the transporter name the CRM returns; on a new development ask whether a developer-appointed transporter was used.
  • The widely repeated '74, 75, 76 or 77' MPRN rule is wrong by omission: the IGT UNC range table v3.21 (November 2025) allocates 74,000,001 to 79,500,000 on the 8-digit core including a 78 band, and three 76/77 numbers belong to a large gas transporter. Treat any prefix test as a hint only.
  • Real MPRNs are 10 digits; the ranges are 8-digit cores with two check digits appended, so a range test must use the first 8 digits.
  • Ofgem states its licensee list is not a Formal Public Register; the count and names are as at 10 August 2026. Historic owner names in the range table (Squire Energy, Murphy Gas Networks, Energetics Gas and others) are not current transporters.
  • No per-iGT connections landing pages, contact details, fees or timescales are recorded because no individual iGT site was fetched.
  • The GDN third-party (IGT/UIP) forms at WWU and SGN are for the iGT or its contractor connecting the site network to the GDN, not for end customers.

Other water routes

Not wholesalers. A development can be served by a new appointment (NAV) instead of the incumbent, which a postcode cannot detect, and the contestable works on a new connection can be self-laid by an accredited provider.

New Appointments and Variations (NAV) route

  • England and Wales, site by site: a NAV holds the appointment for a defined development area (unserved site, incumbent consent, or a premises using at least 50 megalitres a year in England or 250 in Wales, WIA 1991 s.7); no NAV regime exists in Scotland (Ofwat-appointed site-specific water and/or sewerage undertakers (limited companies appointed per site))

  • A postcode lookup returns the incumbent and is silently wrong on a NAV site: two addresses in one postcode district can have different undertakers. Ask the customer whether the site is a new development on an independent network and check the bill or adoption paperwork.
  • Ofwat's register of NAVs granted to date is the only authoritative list and could not be retrieved (403). CCW lists eleven NAVs (Advanced Water Infrastructure Networks / Leaf Water, Albion Water, County Water, ESP Utilities Group, Independent Water Networks, Last Mile Water, LEEP Utilities, Matrix Water, MUA Water, Severn Trent Services, Veolia Water Tidworth) but that is not the register; the Independent Networks Association member list is not a NAV list either.
  • The South East Water SLAs on its NAV page (5, 21, 28 and 90 days) are the incumbent's commitments, not a NAV route timescale.

Frequently asked questions

Who receives a utility connection application?
The network operator for the utility at your postcode: the distribution network operator for electricity, the gas transporter for gas and the wholesaler for water. That covers a new connection, a capacity change, a move of the supply position, a diversion and a permanent disconnection. Jobs on the meter itself (removal, a meter-only move, de-energising and re-energising for works, and on water any job on an existing supply point) go to your supplier or water retailer, because the supplier owns the meter. The tool checks the party first, then names the form.
How do I find which operator serves my postcode?
Enter the site postcode in the tool. If the site already has a meter, pick the address and the operator is read from the meter identifier: the distributor id at the start of an electricity MPAN, the transporter recorded against a gas MPRN, or the wholesaler behind a water SPID, which is exact. On a bare site the operator comes from the postcode alone and is labelled likely, because a postcode cannot tell whether a development is served by an independent network, an independent gas transporter or a new appointment for water instead of the regional operator.
How long does the operator have to send a quotation?
Electricity: the Electricity (Standards of Performance) Regulations 2015 set 5 working days for a single low-voltage single-phase connection, 15 for a small low-voltage project, 25 for other low-voltage connections, 35 for high voltage and 65 for extra-high voltage, from a complete application. Gas: the Gas (Standards of Performance) Regulations 2005 set 4 working days for a standard quotation at or below 275 kWh per hour, 11 for a non-standard quotation at that size and 21 above it. Water: neither instrument sets a quotation period, so the wholesaler's own published levels of service apply. Which period applies is the operator's determination.
What does a connection application need?
A site location plan showing the boundary and the proposed supply position, the load (a schedule of plant in kW or kVA for electricity, the peak hourly load for gas, the flow and pipe size for water), the meter identifier and a recent bill where a supply already exists, proof of title or landowner consent on a bare site or a diversion, a letter of authority where someone applies on the business's behalf, and the programme dates. The result card in the tool lists exactly which of these your job needs.
What is the difference between a service alteration and a diversion?
A service alteration moves your own supply position: the incoming cable, pipe or cut-out goes to a new place on the premises. A diversion moves the network's own assets, such as a cable or main crossing the land, so that you can build. They are different teams and different forms at every operator, and moving only the meter with no cable or pipe change is a third case that belongs to your supplier. The tool separates the three so the application lands with the right team.
Does one application cover electricity, gas and water?
No. Each utility has its own operator, its own forms and its own rules on who receives the job, so a site that needs more than one connection makes one application per utility. Run the tool once per utility; the answers for the site are kept in this browser tab, and each utility has its own page with the routing table, statutory rows and questions for that network: electricity, gas and water.
When does the statutory clock start?
On receipt of a complete application. An application missing the site plan, the load or the authority to act is not complete, and the quotation period does not run until the operator has what it needs. That is why the tool lists the documents for the job before you apply. The operator decides which standard applies to a given job; the tool shows every quotation row for the utility and highlights the one its reading of your answers points to.
Is the application service free?
Yes. We complete the operator's application on the operator's own form and submit it with your authority at no fee. We are paid on the supply contract too, disclosed. On the ongoing gas and electricity contract we earn a commission built into the unit rate (stated in pence per kWh) or an agreed fee, your choice. Every margin is separated so you can see exactly what the service costs.
Does this tool cover Scotland, Wales and independent networks?
The fourteen electricity licence areas include Scotland and Wales, as do the thirteen gas local distribution zones, and the water wholesalers listed include Scottish Water, Dwr Cymru Welsh Water and Hafren Dyfrdwy. A site on an independent distribution network operator (an MPAN distributor id of 24 or above), an independent gas transporter or a new appointment for water applies to that operator instead, which a postcode cannot detect. Where the site already has a meter the tool reads the operator from the meter identifier; on a bare site it asks whether the development has its own network before trusting the postcode.
