A utility bill is a statement from a company supplying an essential service that keeps your home or business running, showing what you used and what you owe. In the UK, the core utilities are electricity, gas and water. Broadband and phone services are often treated as utilities too, while council tax, despite paying for essential services, is not a utility bill at all.
That distinction matters more than it sounds. Whether a document counts as a utility bill decides whether a bank accepts it as proof of address, and understanding what sits inside each bill is the first step to spending less on all of them. This guide answers the definition properly, settles the is-it-or-isn't-it questions one by one, and covers what makes business utility bills a different animal from domestic ones.

What is a utility bill?
The utility bill meaning is simple: a periodic statement, usually monthly or quarterly, from a provider of an essential service. It shows how much of the service you used, the rate you were charged, any fixed daily charges, taxes, and the total to pay.
A utility is any service a property genuinely cannot run without. Electricity, gas and water are the undisputed three. Because modern life has moved online, broadband and phone lines are now widely treated as utilities as well, though not every organisation counts them the same way, which is where the confusion starts.
What counts as a utility bill in the UK?
The table below is the quick answer, including the question most people are really asking: whether the document works as proof of address.

The pattern to notice: counting as a utility bill and counting as proof of address are two different tests. Council tax fails the first and passes the second. A mobile bill can pass the first for some organisations and still fail the second. When a bank or landlord asks for a utility bill, they almost always mean electricity, gas or water, dated within the last three months, showing your name and address.
Is it a utility bill? The common questions answered
Is council tax a utility bill?
No. Council tax is a local government charge that funds services like waste collection and roads, not a bill for a metered service you consume. It is not a utility bill, but most organisations accept a council tax bill as proof of address anyway, often rating it more highly than a utility bill because it comes from a public authority.
Is a phone bill a utility bill?
A landline phone bill is generally treated as a utility bill. A mobile phone bill usually is not, and many banks explicitly reject mobile bills as proof of address because mobile contracts are portable and less tied to a property. If you are gathering documents, use a landline, broadband or energy bill instead.
Is internet or broadband a utility bill?
Increasingly, yes. Broadband is now treated as a modern utility by most organisations, and a broadband bill in your name at your address is widely accepted for proof of address. WiFi is not a separate bill, it is simply how you use your broadband, so the document that counts is the broadband bill itself.
Is a water bill a utility bill?
Yes, one of the core three. The only quirk is supplier choice: households cannot choose their water supplier, but businesses in England and Scotland can, which surprises many owners. Water bills are accepted as proof of address essentially everywhere.
Is a TV licence a utility bill?
No. A TV licence is a legal permission to watch broadcast television, not a charge for a consumed service. Like council tax, though, it is commonly accepted as proof of address because it is an official document tied to your property.
Is rent a utility bill?
No. Rent pays for the property itself, not a service supplied to it. Some tenancies include utilities within the rent, and in that case you have no utility bills in your own name, which can make proof of address harder. A bank statement or tenancy agreement usually fills the gap.
What does a utility bill show?
Every utility bill carries the same anatomy: your name and supply address, an account number, the billing period, what you used, the unit rate, the standing charge, VAT and the total due. Energy bills also carry your supply numbers, the MPAN for electricity and the MPRN for gas, which identify your meters to the industry. We explain the gas side, and what your meter type means for your costs, in our guide to commercial gas meters.
Two lines deserve more attention than they get. The unit rate is what you pay per kWh or per cubic metre used. The standing charge is what you pay every single day regardless of usage. A bill can rise while your usage falls purely because standing charges moved, which is exactly what happened to many UK businesses in 2026.
How are business utility bills different?
Households and businesses receive the same types of utility bills, but the rules underneath them are very different.
No price cap. The Ofgem cap protects domestic customers only. Business rates are set entirely by the market and by the contract you negotiate, which is why two identical premises can pay wildly different prices.
Business taxes. Most businesses pay VAT at 20% on energy rather than the domestic 5%, plus the Climate Change Levy on every unit of electricity and gas, a charge households never see.
More moving parts. Multiple meters, multiple premises, deemed rates when contracts lapse, and supplier choice on water in England and Scotland. Business utilities reward active management in a way domestic ones do not.
Proof of address for the business. Banks, lenders and Companies House processes often ask for a business utility bill in the company name at the trading address, which is one more reason to keep bills accurate and in the right name.
The cost side of this story, and why business energy in particular runs so much higher than domestic, is covered in our guide to why business electricity is so expensive.
How can you reduce your utility bills?
First, know what you are paying. Pull your latest bills and find the unit rate, standing charge and contract end date for each utility. For energy, benchmark them against current business electricity rates to see instantly whether you are above the market.
Second, never let a contract lapse. Out of contract rates on business energy can run 40% to 80% above the market. The renewal date belongs in your calendar, months ahead.
Third, compare the whole market at every renewal. This applies to business electricity, business gas and, for eligible businesses, business water too, because water switching is the saving most companies do not know they have.
Fourth, cut the waste. Smart meters end estimated billing, monitoring shows what runs out of hours, and efficiency upgrades quietly compound. Small percentages across three or four utilities add up to real money.

Where a bill is already competitive, we tell you plainly and move to the next one.
A statement from a provider of an essential service, showing your usage, the rates charged and the amount due. In the UK the core utility bills are electricity, gas and water, with broadband and landline phone bills often treated as utilities too.
What are examples of utility bills?
Electricity bills, gas bills and water bills are the definitive examples. Broadband and landline bills are commonly counted as well. Council tax, TV licences, rent and mobile phone bills are not utility bills, though some are still accepted as proof of address.
Is council tax a utility bill?
No. It is a local government charge rather than a bill for a consumed service. Most organisations still accept a council tax bill as proof of address, often preferring it to a utility bill.
What utility bills count as proof of address?
Electricity, gas and water bills dated within the last three months, showing your name and current address, are accepted almost universally. Broadband and landline bills usually work too. Mobile phone bills are frequently rejected, so avoid relying on one.
What does WET mean on a utility bill?
WET on a water bill stands for water, environmental and trade effluent charges, the wastewater side of the account. If your bill splits water and WET lines, one covers the water supplied to you and the other covers taking it away.
How many utility bills does a business have?
Typically three to five: electricity, gas and water as the core, plus broadband and phone. Multi site businesses multiply that by every premises, which is exactly when consolidated management starts paying for itself.
Not sure if your electricity, gas or water contracts are competitive? Green Light Consultancy Group can review your current utility costs, benchmark them against the market and identify opportunities to reduce unnecessary spend.
