Business utilities

Business utilities matched to how your sites actually run.

Business energy, water and telecoms are easy to overpay on. Headline rates rarely tell the full story, renewal windows close earlier than people expect, and the cheapest tariff today is not always the right one for the next two years. Merchant Advice compares suppliers across electricity, gas, water and telecoms so you can see total cost and contract fit before you sign.

  • Compare suppliers across electricity, gas, water and telecoms.
  • Read contract terms and renewal windows before you commit.
  • Avoid rollover tariffs, deemed rates and restrictive exit clauses.
  • Get adviser support on multi-site procurement and complex cases.
Three routes

Three routes to procuring business utilities

Most businesses end up on one of three procurement routes. The right one depends on how many sites you run, how much you use, and how much time you can give the comparison.

Fixed-rate contract

A unit rate locked in for a defined term, typically 12 to 36 months. Predictable monthly cost, but the renewal window is narrow and easy to miss.

  • Best for budgeting certainty across a known period.
  • Suits single-site SMEs with steady usage.
  • Diarise the renewal window the day you sign.

Flexible or variable contract

The unit rate moves with the wholesale market. Lower cost when wholesale prices fall, exposed when they rise.

  • Best for businesses that can absorb price swings.
  • Suits larger consumers with hedging support.
  • Watch for pass-through charges that move separately.

Multi-site or portfolio procurement

Group several sites under one contract, often with site-level reporting. Buying as a portfolio usually unlocks better unit rates than going site-by-site.

  • Best for chains, franchises and multi-location operators.
  • Suits businesses adding or closing sites mid-contract.
  • Confirm how the contract handles new and exiting sites.
Audience fit

Which kind of utilities buyer are you?

Different consumption profiles need different things from a contract. Tariff type, renewal flexibility and pass-through charges matter more or less depending on how you operate.

Single-site SMEs

One shop, office, salon or restaurant. Low to mid consumption, steady usage. A simple fixed-rate contract usually wins on cost and admin time, provided the renewal window is diarised.

Multi-site operators and chains

Retail groups, hospitality chains, dental groups, franchises. Portfolio procurement and site-level reporting matter as much as the headline rate. Renewal dates are rarely aligned and need to be managed centrally.

High-consumption or specialist sites

Manufacturers, commercial kitchens, gyms, data-heavy sites. Half-hourly metering, capacity charges and green-tariff requirements all factor in. Flexible contracts may suit if there is internal capacity to manage them.

How business utilities pricing actually works

The unit rate is the headline, but it rarely decides what you actually pay each month.

What shapes your real cost

  • Unit rate - a pence-per-kWh charge for electricity and gas, or a price per cubic metre for water. The figure on the quote is rarely the only thing on the bill.
  • Standing charge - a daily fixed fee that applies whether you trade that day or not. It matters more on low-consumption sites than the unit rate does.
  • Pass-through and non-commodity charges - Climate Change Levy, network charges, distribution and policy costs. Some quotes include them, some do not, and a like-for-like comparison only works when they are treated the same way.
  • Contract length, exit fees and rollover terms - typically 12, 24 or 36 months. Renewal windows are narrow and missing one usually drops you onto a deemed or rollover rate that costs more than the original contract.

Headline unit rates are easy to advertise. Total cost depends on consumption pattern, standing charges, pass-through fees and how the contract handles renewal. Higher-consumption or multi-site businesses may also need to plan around capacity charges and half-hourly metering. We help you compare on total commercial fit, not just the rate.

Beyond the rate

What to compare beyond the rate

A good utilities contract does more than lock a rate. The right one fits your consumption pattern, gives you a sensible renewal window, and does not quietly drop you onto a deemed tariff at the end of the term.

Contract length and renewal window

12, 24 or 36 months. Most suppliers require written notice in a narrow window, often two to six months before the end date. Miss it and the contract usually rolls over.

Rollover and deemed rates

What happens if you do nothing? Out-of-contract rates can be 2-3x the contracted rate. Confirm the wording and diarise the action date the day you sign.

Pass-through and capacity charges

Non-commodity costs are often presented separately. Check whether your quote is fully fixed or partly pass-through, and whether half-hourly capacity charges apply to your meter.

Credit, security deposits and switching blocks

New limited companies and businesses with previous arrears can face credit checks, security deposits or supplier objections during a switch. These are normal but worth surfacing early.

Compare the routes

Compare the main routes before you commit

The right procurement route depends on how many sites you run, how complex your consumption pattern is, and how much time you can give the comparison.

Setup Often suits Watch out for Merchant Advice view
Direct to a single supplier Small businesses with a confident view of the market and time to ring round. One supplier, one quote. You only see the deal they want to offer, not whether it is competitive. Fast and simple, but rarely the route to the best total cost.
Online comparison platform Single-site SMEs wanting a quick scan of headline rates. Coverage is uneven, larger and specialist suppliers may not appear, and renewal timing is not managed for you. Useful for a sense of the range; rarely sufficient for multi-site or higher-consumption buyers.
Independent broker or adviser Multi-site operators, higher consumption, complex meters or limited time to manage procurement. Brokers vary. Ask how they are paid, which suppliers they actually compare, and whether renewal is tracked on your behalf. Worth it when total cost, renewal management and contract clarity matter more than the cheapest weekend quote.

Why Merchant Advice

Why use Merchant Advice instead of going direct?

Going direct or relying on a single comparison platform means you only see part of the market. We put suitable suppliers side-by-side so you can judge fit, total cost and contract terms before a single sales process narrows it for you.

Independent comparison

We are not tied to one supplier or one panel. We compare across electricity, gas, water and telecoms based on what fits your consumption pattern.

Negotiation support

We help you push back on the first offer - on unit rates, standing charges, contract length and renewal windows.

Renewal-window management

Already in contract? We track renewal windows so you do not drop onto a deemed or rollover rate when the term ends.

Complex case guidance

Multi-site, half-hourly metered, or had a supplier object during a previous switch? We work with brokers and suppliers who handle the complex cases properly.

Frequently asked questions

Is using a utilities broker right for my business?
Brokers suit businesses that want a clearer view across the market, do not have time to ring round suppliers, or have something non-standard going on - multi-site portfolios, half-hourly meters, prior arrears or a missed renewal window. Single-site SMEs with steady usage can sometimes get a comparable rate going direct, but the renewal management and contract review usually still pay for themselves.
How should I compare total cost beyond the unit rate?
Look at five things together: unit rate, daily standing charge, pass-through and non-commodity charges, contract length, and renewal window. A small difference on the unit rate is often outweighed by a high standing charge on a low-consumption site, or by a missed renewal that drops you onto an out-of-contract rate.
What contract terms usually cause problems later?
Narrow renewal windows, automatic rollover onto deemed rates, partial pass-through quotes that move with wholesale, and capacity charges that apply to half-hourly meters. Always confirm what happens at the end of the term, and what the supplier requires in writing to switch when the contract ends.
How long does switching take, and when can I switch?
A clean switch typically completes in four to six weeks once a contract is signed. You can normally only switch within a defined renewal window before your current contract ends - often two to six months before the end date - so the action date matters as much as the supplier comparison.
What happens if I miss the renewal window or end up on a rollover?
Most suppliers move you to a deemed or out-of-contract rate, which is usually significantly higher than the contracted rate. You can switch off a rollover, but the new supplier needs your details, your existing supplier needs notice, and any outstanding balance with the current supplier needs to be cleared first. It is fixable - just more work than switching on time.
How does multi-site procurement work?
Sites are grouped under one contract with site-level reporting, usually with aligned end dates so the whole portfolio renews together. Buying as a portfolio normally unlocks better unit rates than going site-by-site, and the contract should explain how new sites are added and exiting sites are removed mid-term.
Do brokers add fees to my unit rate?
Brokers are paid a commission by the supplier, built into the unit rate as a small uplift. The market standard is to disclose this clearly. The cost is usually offset by access to a wider supplier panel, better contract terms and active renewal management. Ask any broker how they are paid and which suppliers they compare against.
What is the difference between business and domestic utilities?
Business contracts have separate tariffs, different VAT treatment, longer terms, narrower renewal windows and stricter credit checks. Switching is supplier-led, with the new supplier serving notice on the old one within a defined window. The fundamentals look similar to domestic accounts, but the contractual mechanics behave differently.
