How business gas works in Exeter
Somewhere in Exeter this morning a Quayside restaurant lit its ranges, a trade counter on Marsh Barton turned its heaters on and an office at Sowton brought its boilers up for the day. All three got their gas through pipes owned by Wales & West Utilities, through its South West network. None of them pays Wales & West directly. The network carries the gas, a shipper moves it on the supplier’s behalf, and the supplier sends the bill. The supplier is the part you can compare.
The rules are national. There is no price cap on business gas, no published tariff and no cooling-off period once you have signed. Every quote is built for one meter, from how much it uses and when, the credit profile behind it, the meter type and where wholesale gas is trading on the day.
What is local is the transportation charge, and the edges of the grid. Exeter, Topsham, Exmouth, Cranbrook and the business parks around the M5 are on the mains, all within Wales & West’s South West zone, so the network part of the bill is set on the same regional basis. Across much of rural Devon, premises run on oil or LPG instead.
Exeter’s gas demand is mostly heating in offices and institutions. The business parks at Sowton and the Science Park are heating-only; the university, the hospital and the Met Office are round-the-clock estates; Marsh Barton and Matford run workshops and trade counters with seasonal loads; and the city centre and Quayside hospitality trade burns gas in short daily peaks. None of them needs a bespoke energy team, and most could be paying less.
Who runs the pipes in Exeter and who sends the bill
Wales & West Utilities owns and maintains the pipes under Exeter, runs the gas emergency line and connects new supplies. It is paid through transportation charges your supplier collects within the unit rate and standing charge, under Ofgem price controls. You cannot choose or switch your network. The supplier is the moving part.
Every supply point has an MPRN, the Meter Point Reference Number printed on each bill. That number, not your account number, is what a supplier needs before they can quote. If your Exeter site was connected more recently through an independent gas transporter rather than Wales & West Utilities’s network, the MPRN works exactly the same way. Only the pipe owner differs.
Electricity is a separate network with a separate company. In Exeter that is National Grid Electricity Distribution. If you buy both fuels, our business electricity in Exeter page covers that side, and business energy covers buying the two together.
What goes into an Exeter business gas price
Four lines make up the bill. The unit rate does most of the work, the standing charge quietly adds up, and the other two are taxes you can sometimes reduce but never negotiate.
| Part of the bill | What it is | What sets it |
|---|---|---|
| Unit rate | Pence for every kWh of gas used. The largest line on most bills. | Wholesale gas on the day you ask, the regional transportation charges for your zone and the supplier’s margin. |
| Standing charge | A fixed daily fee for the connection, charged whether or not any gas is used. | Meter type and network region. A low unit rate paired with a high standing charge can cost more over a year, so compare the annual total. |
| Climate Change Levy | A government tax on business energy, shown as its own line at 0.801p per kWh from April 2026. | Set nationally. Some manufacturers and charities can claim relief. |
| VAT | 20 percent as standard on business gas. | Drops to 5 percent automatically for very low usage (the de minimis thresholds are 33 kWh a day of electricity or 145 kWh a day of gas), and for charitable non-business or domestic use if you claim it with a VAT declaration. |
After those four, the number that matters most is annual consumption. Under roughly 25,000 kWh you are a small user and suppliers price from a matrix. Above about 150,000 kWh every quote is bespoke. The largest Exeter sites, past 500 MWh a year, can buy in tranches on a flexible contract rather than fixing everything on one afternoon.

Fixed, variable or flexible for an Exeter business
Most small and medium businesses in Exeter end up on a fixed rate for one to three years. It is not automatically the safe choice. You are paying for certainty, and if wholesale prices fall halfway through the term you will watch newer contracts come in lower and be able to do nothing about it.
| Contract type | How it prices | Who it tends to suit |
|---|---|---|
| Fixed | Unit rate and standing charge locked for the term, usually one to three years. | Most Exeter businesses. Budget certainty, at the cost of a premium and no benefit if wholesale falls. |
| Variable | Tracks the market up and down, normally with a margin on top. | Businesses that can absorb a bad month and want to follow prices down. |
| Flexible | Gas bought in portions across the year rather than fixed in one go. | Sites above about 500 MWh a year, or multi-site groups buying as a portfolio. |
Whatever you sign, write down the termination window. Larger businesses are usually asked for written notice somewhere between 30 and 180 days before the end date. If you are a microbusiness, Ofgem caps the notice a supplier can require at 30 days, and many microbusiness fixed-term contracts need no notice at all. Miss it and you can be moved onto out-of-contract rates, which can run 50 percent or more above a negotiated deal. It is one of the most expensive things that can happen to a business gas account, and one of the easiest to prevent.
Switching business gas supplier in Exeter
Nobody comes out. No pipe is touched and the meter stays where it is. Once you sign with a new supplier they arrange the transfer with your old one, the MPRN stays the same, and the only thing that changes is the name on the bill. The transfer itself can go through in as little as five working days. Your existing contract’s notice period is what sets the real timeline.
What a business gas comparison looks like in Exeter
A comparison is not a list of unit rates. For an Exeter meter we start with the MPRN and twelve months of consumption, then price the same usage across the suppliers on our panel so the figures are like for like. Each quote is shown as an annual cost, with the standing charge, Climate Change Levy and VAT included, because a cheap-looking unit rate attached to a high daily charge is a common way to end up paying more.
We also check three things most renewal letters leave out: whether your meter class matches what you actually use, whether you qualify for reduced VAT or Climate Change Levy relief, and whether the termination terms on the new contract are ones you can live with in three years’ time. If your current supplier’s renewal is the best option, we say so.

Exeter businesses we work with
Exeter’s gas users are led by offices and professional services, then a hospital and university estate, hospitality in the centre and on the Quayside, trade and workshops at Marsh Barton, and food and farm businesses across Devon. The sector pages go into that detail: business gas for offices, business gas for hospitality, pubs and restaurants, business gas for manufacturing and industrial sites and business gas for logistics and warehousing.
For the national picture start with business gas. If you run more than one site, multi-site business energy management explains how we handle an estate as one portfolio, and what an energy broker does covers how we are paid.
“Clearsight Energy have provided a quick and efficient service to our Parish Council. No pressurised selling was involved, just clear and constructive advice. We will look to using them in the future when our other utility contracts are up for renewal.”

Frequently asked questions
Who supplies business gas in Exeter?
Any licensed UK business gas supplier can take on an Exeter meter. The pipes belong to Wales & West Utilities and never change hands. Switching changes the supplier and the price, not the network.
Is Exeter in the same gas zone as Plymouth and Bristol?
Yes. The whole of the South West from Bristol to Cornwall sits in Wales & West’s South West network, so the regional transportation charges are set on the same basis. Differences between quotes come from the meter, not the city.
Our Exeter office only uses gas for heating. Is a comparison worth it?
Usually yes. Heating-only loads are strongly seasonal, so the standing charge is a large share of the bill and varies widely between suppliers. Comparing the annual cost rather than the unit rate is where the saving tends to be.
Where is the MPRN on an Exeter gas bill?
The Meter Point Reference Number, up to ten digits, is printed on every bill near the meter details. It identifies the supply point rather than your account and is what a supplier needs before quoting. It does not change when you switch.
Our farm shop or rural business near Exeter is on oil. Can you help?
A supplier comparison needs an MPRN, so it does not apply to oil or LPG. We can still review the electricity supply, and if a mains connection is realistic our meter installation team can explain what is involved.
Does Clearsight Energy cover Torquay, Barnstaple and the rest of Devon for gas?
Yes. The mains-gas parts of Devon all sit in Wales & West’s South West network and we compare for any connected business meter in them.
How much notice does an Exeter business need to give its current gas supplier?
Check the contract. Most suppliers require written notice between 30 and 180 days before the end date, and some still move smaller customers onto out-of-contract rates if it is missed. Serving notice does not commit you to switching; it keeps the option open.
Can several Exeter sites go on one business gas contract?
Usually yes. A multi-site contract brings every MPRN under one supplier, one end date and one set of terms, and larger portfolios can buy on a flexible basis. We compare the estate as a whole rather than site by site.
Does an Exeter business need a smart meter to switch gas supplier?
No. Any meter type can be switched. Some suppliers offer to fit a smart or AMR meter after the switch, which is optional for most sites and useful for accurate billing.
What if my Exeter premises are on an independent gas transporter?
Only the pipe owner differs. Your MPRN works the same way and any licensed supplier can quote. Some suppliers price IGT sites slightly differently because of the transporter’s charges, which is one more reason to compare several rather than accept the first renewal offer.
How is Clearsight Energy paid for comparing business gas in Exeter?
By the supplier you choose, through a commission built into the contract rate. We show the pricing side by side and explain the trade-offs; you decide. How we make our money sets it out in full.
