Business Gas Meter Installation - A Quick Summary

Installing a new business gas meter isn’t the same as switching supplier. It’s a physical install, with specific costs (£800 to £2,000 for a standard low-load meter, £2,000 to £8,000 for higher-load), specific lead times (4 to 12 weeks once the supply pipework is in), and a specific cast of players: the Gas Distribution Network (GDN) that owns the local main, a Meter Asset Manager (MAM) that owns and installs the meter, and your supplier who bills for the gas itself.

This guide walks through every part of the process — which type of meter you actually need, what the MAM does and why you can choose your own, what really drives the cost, and what catches businesses out. It also covers what Clearsight handles when we project-manage an install for a client (no upfront fees, paid by the supplier you eventually contract with).

If you’re getting a new gas connection at a site with no existing supply — that’s a different process and you want our [new business gas connection guide](/new-business-gas-connection/). This guide assumes the supply pipework exists and you need a meter.

You’re here because you need a new gas meter installed at a business premises. Maybe you’ve taken on a building with no meter, or you’ve inherited a faulty one, or you’ve outgrown the meter you had. Either way: the install isn’t a single transaction, and it’s not something the supplier handles end-to-end. Here’s how it actually works.

The short version: a new business gas meter install in the UK typically costs between £100 and £1,200 depending on meter size, takes 2 to 6 weeks, and involves your Meter Asset Manager (MAM), your supplier, and sometimes your Gas Transporter. Below, the full process and how to get the price down.

When you need a new gas meter installed

Five scenarios:

  1. Existing supply, no meter (or a broken one). The pipework is there, but the meter needs installing or replacing.
  2. Meter upgrade. Demand has grown. You’re moving from a G4 to a U6, or from a U6 to a U16, or to a daily-metered (DM) meter.
  3. Smart meter rollout. Your supplier is offering to swap your existing meter for a SMETS2 smart meter as part of national rollout.
  4. Faulty or end-of-life meter. Mechanical meters wear out, especially after 15 to 20 years. Suppliers will sometimes proactively flag this.
  5. Change of supplier requires a meter change. Rarer, but happens occasionally when a new supplier prefers a different MAM and meter type.

If you don’t yet have a gas connection at all, meaning no pipework into the building, what you need is a new business gas connection, not just a meter install. That’s a separate (longer, more expensive) process.

Who’s involved in a business gas meter install

Three parties:

You don’t normally deal with the MAM directly. Your supplier (or your broker, that’s us) coordinates with them on your behalf.

Typical costs in 2026

The cost varies based on meter type and whether the install is straightforward:

Meter typeTypical install cost
G4 gas meter (small commercial)£100 to £200
U6 gas meter (small to medium commercial)£180 to £400
U16 gas meter (medium commercial)£400 to £700
U25 / U40 gas meter (larger commercial)£700 to £1,200+
Daily Metered (DM) meterBespoke quotes, often £1,500+
Smart meter (SMETS2 commercial)Usually £0 (supplier-funded)

Indicative ranges only. These are not live quotes. The wholesale market and MAM pricing both move. The figures shown reflect what Clearsight typically sees across the UK during early 2026 for standard urban commercial sites. Bigger sites, awkward access, or rural locations push prices up. Your specific quote will depend on your site, your supplier’s MAM relationship, and the work required.

How long it takes

Most business gas meter installs run 2 to 6 weeks from order to live meter. The breakdown:

Smart meter installs sometimes run faster because suppliers have dedicated rollout teams. DM meter installs on the other hand can run 8 weeks or longer because of the additional commissioning steps.

What can delay an install

The two most common delays:

  1. MAM scheduling capacity. Especially in autumn and winter when demand spikes. Booking 4 to 6 weeks ahead is normal in busy periods.
  2. Site access issues. If the meter position is hard to reach, behind locked doors, or requires lifting flooring, the MAM may need to schedule a follow-up visit. Get site access details right at order time.

Less common but worth knowing: gas safety certificate (CP12) issues can hold up new tenant installs, and any historic dispute on the supply point (unpaid bills from a previous tenant on the same MPRN) needs to be cleared first.

How to make sure you get a fair price

Three things:

  1. Don’t just accept your incumbent supplier’s MAM quote. Suppliers usually have one preferred MAM and the price isn’t always competitive. A broker can quote across multiple MAMs to find the best price for your meter size.
  2. Be specific about the meter type you need. Over-spec’ing the meter (e.g. fitting a U16 where a U6 would do) inflates both the install cost and ongoing standing charges. A site survey or basic demand check sorts this.
  3. Confirm the install includes commissioning and certification. A “bare install” quote without commissioning leaves you needing a follow-up visit. Get the price for install + commission + go-live.

Working with Clearsight on a gas meter install

We coordinate the meter install end-to-end: sourcing competitive MAM quotes, scheduling with the supplier, making sure the site access is clean, and confirming the supply is on the right contract once the meter is live. No upfront fees; we’re paid by the suppliers we recommend.
