What does this cost to run?
Best for heaters, dehumidifiers, showers, laundry appliances, kitchen use and general electrical devices.
- Use when you need a direct cost baseline.
- Best if you already know the appliance or usage pattern.
UK household energy answer engine
Find the running cost, likely saving, right size, or better option without digging through guesswork
Home Energy Scout is for ordinary UK households trying to answer a practical energy question quickly. Start with the question you have, get a sensible estimate, then move straight to the next useful step.
Where most people should start
- I know the wattage and want a cost.Use the general appliance calculator for a quick baseline.
- I am trying to heat a room cheaply.Start with heater running cost, then compare options if needed.
- I want to know whether an upgrade pays back.Start with the savings calculators for LED lighting, loft insulation or an old fridge replacement.
- I think the room or appliance may be the wrong size.Check sizing before blaming the tariff or the appliance.
Start With Your Situation
Pick the route that matches the problem you are actually trying to solve right now.
Baseline first
My bill feels higher than it should
Start with a running-cost page, then move into savings or compare once the current cost is clear.
Check the fit
This room still feels wrong
Use the sizing pages when the real problem may be room demand or appliance mismatch rather than tariff alone.
Judge payback
I want an upgrade to earn its keep
Use the savings section when the next question is yearly saving, simple payback and whether the job is really worth doing.
Choose the route
Two options look similar on paper
Move into compare when you need a verdict on cost, speed, comfort or convenience rather than another general explanation.
Choose the route that matches the job you are trying to do
Start with the question, not the category name.
How much could I save, and is it worth it?
Best for insulation, controls, glazing and replacement decisions where payback and practical value both matter.
- Useful when the question is financial, not just technical.
- Includes calculator-led payback tools as well as comfort-led routes.
What size do I need?
Best when a room feels cold, damp or slow to dry and you suspect the unit may simply be the wrong size.
- Helpful before buying or replacing heaters and dehumidifiers.
- Often explains high bills better than generic advice.
Which option is the better fit?
Best when two options look similar on paper but differ in running cost, speed, comfort or convenience.
- Designed to return a verdict, not a feature dump.
- Useful for heating and indoor drying choices.
Best starting tools
These are the strongest first clicks when you want a quick answer and are not yet sure where the decision will lead.
Appliance running cost calculator
Quick baseline for almost any electrical appliance when you know the wattage, minutes, hours or cycles.
Electric heater running cost calculator
Useful for room-heating cost with a more realistic runtime pattern than a flat full-power assumption.
Dehumidifier running cost calculator
Strong route for damp control and indoor drying questions, especially when the next decision is method choice.
Loft insulation savings calculator
Estimate annual saving and simple payback instead of relying on broad “insulation saves money” claims.
Heater room size calculator
Check whether the room likely needs more heat than expected before over-focusing on heater type.
Heating option comparison calculator
Compare electric heating options with a verdict that reflects room use, not just headline kWh numbers.
Common household routes
Drying clothes indoors
Start with dehumidifier running cost, then move into dehumidifier vs heating or heated airer vs tumble dryer.
Heating one room cheaply
Check room size first, then use heater running cost and heater comparisons.
Cutting a stubborn bill
Go to the savings hub and separate quick-payback changes from bigger comfort-led upgrades.
Replacing an old appliance
Use repair vs replace or the old fridge savings route if the problem appliance is already clear.
Why these pages are more useful than a generic blog post
- They start with the household question rather than a broad topic intro.
- They explain the assumptions instead of hiding them behind vague averages.
- They push you toward the next decision instead of ending at one isolated number.

How the estimates work
The site aims to be practical, not falsely precise. That means clear assumptions, UK-first framing and plain-English interpretation.
Tariff-led mathsRunning-cost pages use appliance power, use time and tariff to calculate cost.
Usage assumptions shownHeaters, insulation and drying routes explain where assumptions matter most.
Payback kept realisticSavings pages separate quick wins from slower comfort-led upgrades.
Methodology linked clearlyCheck how the estimates work whenever the answer depends on rougher assumptions.
Frequently asked questions
Quick answers to the questions people usually have before trusting any home-energy estimate.
Are these running costs exact?
No. They are estimates based on the figures and assumptions used on the page. Actual cost depends on your tariff, appliance efficiency, room conditions and how you use it.
Do I need my exact tariff for the calculators to be useful?
No, but it helps. The tools work best when you use your actual electricity or gas unit rate. If you do not know it yet, the defaults still give you a sensible starting point.
Why do some pages talk about comfort as well as payback?
Because some upgrades are chosen for warmth, draught reduction or convenience as much as for bill savings. Treating every upgrade as a strict payback calculation would make the advice less useful.
What should I click after I get one result?
Usually a comparison page, a sizing check or a savings route. The hubs are designed to move you from one answer into the next practical decision instead of stopping at the first number.
