How do you compare business electricity prices in Cambridge?
Clearsight Energy compares business electricity prices for Cambridge businesses across a wide panel of UK suppliers. Cambridge sits on UK Power Networks’ Eastern network, so every supply in the city has an MPAN beginning 10 and the same regional network charges. Send us a recent bill, we price the meter like for like, you choose, and we handle the switch.
- Network operator. UK Power Networks, Eastern region.
- MPAN prefix. 10.
- Switching time. Four to eight weeks, no interruption to supply.
- Contract types. Fixed, pass-through or flexible, one to five years.
- What is negotiable. Wholesale timing, supplier margin and standing charge. Network charges and taxes are not.
Cambridge has a problem most cities would like to have. Demand for electricity from new labs, data centres and research buildings has grown faster than the network can be reinforced, and for several years the honest answer to a large new connection request in parts of the city has been a long wait. That’s the single most important thing to understand about business electricity in Cambridge, and it has nothing to do with the price per kWh. Around the science campuses sits an ordinary city: colleges, hospitality in the centre and on Mill Road, retail, professional services, and light industrial on the northern estates and out at Waterbeach.
This page covers what sets a Cambridge business electricity price, where Cambridge businesses most often overpay, how the local network works, and how we compare and switch. If you’d rather just send a bill, start here.
Why do Cambridge businesses pay more for electricity than they should?
Almost every Cambridge bill we review has at least one of these on it. None of them shows up as a line called “overpaying”. They show up as a unit rate that looks fine and an annual total that isn’t.
Signing a lease before asking about capacity
A lab or a data-heavy office needs far more authorised supply capacity per square metre than the building it replaces was designed for, and in parts of Greater Cambridge that capacity is booked years ahead. The network conversation belongs alongside the lease negotiation, not after the fit-out is designed. No supplier can shortcut it.
An ordinary business priced as a lab
A ten-person office near the station has nothing in common with the research building three streets away, but a supplier working from an estimate rather than data may price you as if it did. Twelve months of actual consumption is the thing to hand over first.
Rolled-over contracts in short-lease space
Cambridge has a high turnover of office and hospitality tenants. The contract end date leaves with the last occupier and the next one lands on out-of-contract rates.
Comparing unit rates instead of the annual bill
Standing charges vary widely between suppliers for the same meter. The lowest unit rate is often not the cheapest year.
VAT and Climate Change Levy relief not claimed
Colleges, churches, charities, community venues and very low users can pay 5% VAT and be exempt from CCL, but only with a declaration. Cambridge has an unusual number of all of them.
Where does a Cambridge business electricity bill actually go?
A Cambridge business electricity bill is wholesale energy, the supplier’s margin and standing charge, network charges set by UK Power Networks for the Eastern region, and taxes. The first three are negotiable. The network charges and the taxes are not, whichever supplier you choose. Here’s how that breaks down.
| Part of the price | What sets it in Cambridge | Can you negotiate it? |
|---|---|---|
| Wholesale energy | The market on the day you fix. Same across Great Britain. | Yes, through timing and contract type |
| Supplier margin | Each supplier’s own pricing for your credit profile, consumption and meter type. | Yes, this is where comparison works |
| Standing charge | Set by the supplier. Varies widely between quotes for the same meter. | Yes, compare it alongside the unit rate |
| Distribution (DUoS) | UK Power Networks, Eastern region, MPAN prefix 10. | No, set regionally |
| Transmission (TNUoS) | Mostly a fixed charge banded by site size since 2023, with a small locational element. | No, set nationally |
| Climate Change Levy and VAT | Taxes at national rates. | Only through reliefs, such as 5% VAT for low use or charities, or a climate change agreement |
Who runs the electricity network in Cambridge?
UK Power Networks runs the electricity network in Cambridge under its Eastern licence, and every Cambridge MPAN begins with 10. UK Power Networks runs the Eastern licence, the old Eastern Electricity area, which stretches from the edge of London through Cambridge to the Norfolk coast. Cambridge, Peterborough, Huntingdon, Ely, Newmarket and Bury St Edmunds are all on the same network with the same regional charges. Head north-west past Peterborough and you cross into National Grid Electricity Distribution’s East Midlands region with MPANs beginning 11.
The Eastern zone sits in the upper half of the national transmission charging map, above the Midlands and the north but below London and the south coast. On a large half-hourly supply that’s a visible line. On a small supply it’s inside the unit rate. The regional distribution charge averages the dense southern fringe near London with a very large, sparsely populated rural east, so a Cambridge research building and a Fenland farm pay the same rate despite costing the network wildly different amounts to serve.
Confirm it from your bill. The first two digits of your MPAN are the distributor ID. For Cambridge that’s 10. The network recovers its costs through DUoS charges collected by whichever supplier you use, and you can’t switch away from it. What you can switch is the supplier.
How does switching business electricity supplier work in Cambridge?
Any business in Cambridge can switch electricity supplier, the switch is paperwork, it takes four to eight weeks and nothing at the site changes. Every licensed supplier can quote any GB meter, so your region doesn’t limit who will price you, only the network element they all pass through. We compare quotes from a range of licensed UK suppliers, and you can see who we work with on our suppliers page. Here’s how a comparison runs from start to finish.
We take the MPAN, meter type, contract end date and twelve months of consumption from a recent bill. If the current rate is out of contract or rolled over, we say so.
Your Cambridge meter is priced by our supplier panel on the same start date and term, so the quotes are directly comparable. Fixed, pass-through and flexible options where they apply.
Unit rate, standing charge and the annual cost side by side. The lowest unit rate is not always the lowest bill, and we’ll show you why.
We serve notice on the old contract, handle the transfer, and remind you well before the next termination window so it never rolls over again.
Which businesses in Cambridge do we work with?
We work with businesses across the city and the county, from the centre, the Science Park, the Biomedical Campus, West Cambridge and Granta Park to Mill Road, Chesterton, Cherry Hinton, Trumpington and Waterbeach, and out to Ely, Newmarket, Huntingdon, St Ives, St Neots, Royston and Saffron Walden. Most of what we price in Cambridge is offices, schools and education, pubs, restaurants and hospitality, hotels and manufacturing and industrial sites, with regular work for charities, farms and agriculture and retail.
If you run several sites, in Cambridge or across regions, multi-site business energy explains how we handle an estate as one portfolio, and what an energy broker does covers how we work.

Clearsight Energy have provided a quick and efficient service to our Parish Council. We will look to using them in the future when our other utility contracts are up for renewal.
Should a Cambridge business take a fixed, pass-through or flexible electricity contract?
Most small and medium businesses in Cambridge are best served by a fixed price for one to three years, and larger half-hourly sites are the ones that should look at pass-through or flexible. A fixed contract buys certainty, at a premium, and you get no benefit if wholesale prices fall during the term. A pass-through contract fixes the energy and lets the network charges float, which suits a site with steady load and a finance team that can handle a variable line. Flexible procurement buys energy in tranches and is normally for larger half-hourly sites or multi-site groups.
Whatever you sign, write down the termination window. Most suppliers want notice in writing somewhere between 30 and 180 days before the end date. Miss it and you can be rolled onto out-of-contract rates, which is the single most expensive thing a busy business does with its electricity and entirely avoidable.

Cambridge business electricity questions
How do I compare business electricity prices in Cambridge?
Send us a recent bill so the MPAN, meter type, contract end date and annual consumption are known. We price the meter across our supplier panel on the same start date and term, show you the annual total for each option, and handle the switch if you go ahead.
Who is the electricity distributor for Cambridge?
UK Power Networks, under its Eastern licence. It covers Cambridgeshire, Norfolk, Suffolk, Essex, Hertfordshire and Bedfordshire. Cambridge MPANs begin with 10.
Why is it so hard to get a new electricity connection in Cambridge?
Demand from new labs, research buildings and data-heavy offices has grown faster than the network can be reinforced. In parts of Greater Cambridge, capacity for large new connections has been booked years ahead. It’s a network operator constraint and no supplier can shortcut it, so the conversation belongs at the start of any project.
Are Cambridge and Milton Keynes on the same electricity network?
Yes. Both are UK Power Networks Eastern with MPANs beginning 10. Nottingham and Leicester, by contrast, are National Grid Electricity Distribution East Midlands with MPANs beginning 11.
Is business electricity cheaper in Cambridge than in London?
The energy costs the same. Transmission charges in the Eastern zone are lower than in London but higher than in the Midlands and the north. On a large half-hourly supply that’s visible. On a small supply it’s inside the unit rate.
Does switching electricity supplier interrupt the supply?
No. The meter, the cables and the network operator all stay the same. The change is to who bills you. A switch typically completes in four to eight weeks.
Can a Cambridge college or charity pay less VAT on electricity?
Charitable non-business use and very low consumption qualify for 5% VAT and CCL exemption, but only if a declaration is submitted to the supplier. We’ll check whether you qualify as part of the review.
We’re moving into lab space. What should we ask before signing?
What authorised supply capacity comes with the unit, whether it’s on its own MPAN or a landlord recharge, and what the network operator’s timeline is for any increase. Those three answers decide more than the unit rate does.
Who supplies electricity to businesses in Cambridge?
There is no single electricity supplier for Cambridge. UK Power Networks owns and runs the local network, and that is the same for every business in the area, but the supplier that bills you is your choice from any licensed supplier in Great Britain. If your business has never switched, you are most likely with whichever supplier the previous occupier or the developer set up, often on a deemed or rolled-over rate, and that is the first thing worth checking.
Why is my business electricity bill so high in Cambridge?
The usual reasons, in order of how often we see them: the contract has ended and rolled onto out-of-contract or deemed rates; the standing charge is high for the size of the supply; a half-hourly site is paying for more authorised capacity than it uses; or the quote was priced off an estimated profile rather than real consumption. The Cambridge-specific element is the network charge set by UK Power Networks, which is the same for every supplier and cannot be negotiated. Everything else can be.
What is the average business electricity price in Cambridge?
There is no published average for Cambridge that is worth relying on. A business unit rate depends on the wholesale market on the day you fix, your meter type, your annual consumption, your credit profile and the contract length, so two businesses on the same street can be quoted very differently. The only part that is truly local is the distribution charge for the Eastern region. The useful benchmark is a like-for-like quote on your own MPAN, which is what we produce from a recent bill.
How do I get quotes from multiple electricity suppliers in Cambridge?
Send us one recent bill. That gives us the MPAN, meter type, consumption and contract end date, and we price the meter across our supplier panel on the same start date and term so the quotes are directly comparable. You see the annual total for each option, not just the unit rate, and you can see who we work with on our suppliers page. Going to each supplier yourself works too, but you will get quotes on different dates and terms that are hard to compare.
How long does it take to switch business electricity supplier in Cambridge?
Typically four to eight weeks from signing to the new supplier taking over, and it can be lined up further ahead so the new contract starts the day the old one ends. Nothing physical happens at the site: the meter, the cables and UK Power Networks all stay the same, and there is no interruption to supply.
Can I switch business electricity supplier in Cambridge while I am still in a contract?
Not before the current contract ends, but you can agree the next one now. Most suppliers let you sign a new contract up to twelve months ahead of your end date, and you serve notice on the existing contract inside its termination window. That is how you avoid the gap where out-of-contract rates apply.
