Cheapest Energy Supplier for Student Houses: What to Check Before Switching

Energy bills sneak up on you. One minute, you’re moving into your student house, blissfully unaware of what a standing charge even is. Next, you’re getting a bill that genuinely makes you want to cry. The good news? You probably don’t have to just accept whatever deal came with the house.

Here’s what to check before switching energy suppliers, because the cheapest energy deals aren’t always what they look like at first glance. Some might say they’re the catfish of the admin world.

First: Can you actually switch?

Not everyone can, so it's worth checking before you go any further. You’re good to switch if:

• You’re named on the tenancy agreement and pay energy bills directly to a supplier
• The property has its own meter, not a communal supply
• Your housemates are on board if it’s a joint tenancy

You can’t switch if your bills are included in your rent, if you’re in halls, or if your landlord controls a communal supply. If you’re not sure, check your tenancy agreement or ask your landlord directly.

Understand the price cap first

Your parents have probably lost their minds over the price cap at some point without you paying much attention. But now is the time for you to lock in. Before comparing any deals, you need to know what you’re comparing against. The energy price cap is the maximum amount suppliers can charge per unit of energy - it’s set by Ofgem and reviewed every three months.

From July 2026, the cap rises to £1,862. That’s a 13% jump from the previous cap, and it’s a big reason to look at fixing your rate sooner rather than later.

The cap doesn’t mean you’ll pay exactly that amount. It means that’s the ceiling on unit rates and standing charges. Actual bills depend on how much energy your house uses, which, in a shared student house with everyone gaming, streaming, and forgetting to turn the heating down, can vary a lot.

This is especially true for student electricity bills, where usage habits across a full house can push costs well above the typical household estimate.

Fixed vs variable: Which is better?

This is the one that really matters. Everything else is details.

Variable tariff

• Moves with the market - cap can go up or down
• Usually no exit fees, so you can switch whenever
• Currently means you’re subject to the price cap

Fixed tariff

• Locks in your unit rate for the length of the deal
• Good for budgeting - you know exactly what you’re paying per unit
• Usually has exit fees if you leave early, so check the length against your tenancy

Right now, some fixed deals are sitting below the July price cap level, which means locking in could save you decent cash before the rise hits. Some fixes are currently available from around £1,591 per year compared to the incoming £1,862 cap. That’s a potential saving of over £270 on a typical household’s usage before you even look at usage habits.

What to compare

When you’re looking at energy deals, the headline monthly price isn’t the whole story. Check these before committing:

• Unit rates - the price per kWh of electricity and gas. This is what your usage is charged against
• Standing charge - a fixed daily fee just for being connected, no matter the usage - yay! In a low-usage student house, this can be a bigger chunk of the bill than you’d expect
• Exit fees - if there’s an early exit charge and your tenancy ends before the deal does, you’ll either pay to leave or stay on a supplier you don’t want
• Annual price rises - some fixed deals still include clauses allowing mid-contract increases. Read the small print
• Direct debit discounts - some suppliers knock money off for paying by direct debit and going paperless. Small, but worth factoring in

The stuff nobody tells you before you move in

A few things that catch students out:

Take meter readings the day you get your keys

This is the one everyone forgets and then absolutely regrets. Seriously, do this before you unpack a single box. If you don’t, you could end up paying for the previous tenants’ energy usage. Take photos with a timestamp just in case.

The “deemed tariff” trap

When you move into a property, you automatically inherit whatever deal the previous tenants were on, or a default “deemed tariff” from the existing supplier. These are almost never competitive. Students who don’t switch or compare are often overpaying by £300-600 a year on a shared house bill without realising.

Switching is faster than you think

These days, switching takes around five working days once your new supplier contacts the old one. You don’t have to do much; the suppliers handle it between themselves. You just need to give your new supplier a meter reading.

Your landlord’s approval isn’t required to switch energy suppliers

Common misconception. As long as you’re the bill payer and the property has its own meter, it’s your call.

Sort the bill-payer situation early

One person has to be the named account holder, and that person is responsible for payments if anyone goes quiet. Before anyone signs anything - and before you start comparing student bill packages - get these sorted:

• Pick someone reliable who’s staying for the full tenancy
• Set up a shared bills account so everyone contributes before the direct debit goes out - no chasing, no drama
• Agree on how you’ll handle it if someone moves out mid-year

Cheaper energy: Sorted. Everything else: Also sortable

Switching to a cheaper energy deal is one of the quickest wins you can get on student bills. Once that’s ticked off, there are ways to save across pretty much everything else too.
