Working out your energy usage
Knowing how much gas and electricity you use makes it much easier for you to work out exactly what sort of savings you can achieve by switching energy tariffs.
If you just guess, energy providers won't be able to provide accurate quotes showing what you would pay were you to switch to one of their tariffs.
The easiest way to find the information you need is to look on a recent bill (particularly if it based on actual meter readings and not estimates).
But if you don't know exactly how much energy you use - perhaps because you have recently moved into a new home - you will need to provide energy companies with an estimate.
Getting the correct results
It used to be the case that you'd need to decide whether you were a 'high', 'medium' or 'low', but this way of estimating energy use this was a bit too basic and didn't always produce the correct results.
Now MoneySuperMarket has a new tool to help you work out how much energy you're likely to use, which has been developed with the Building Research Establishment (BRE).
BRE has helped put together the tool using data they collect for the English Housing Stock Condition Survey (a survey which monitors the condition and energy efficiency of houses in England).
This data also forms the basis of the RdSAP (Reduced data Standard Assessment Procedure) system. This is used to work out the Energy Performance Certificates (EPCs) you need to produce when you sell your house.
If anything, the tool will tend to over-estimate your energy usage slightly, but it's better to slightly over-estimate, rather than under-estimate and be hit by an unexpected big bill later on.
Working out your estimate
To help you work out an estimate, MoneySuperMarket's tool asks you to answer several simple questions. These questions are:
- What is the postcode?
- Do you use gas in the property?
- What type of property do you live in? (House/flat etc.)
- When was your home built?
- How many bedrooms does it have?
- How many adults live there?
- Generally when do you use energy in the home?
The data is calculated starting with the average in your postcode area and then this is amended by different factors depending on your answers to the questions.
We're extremely confident that, using the BRE data and the information you provide, we can deliver an extremely accurate quotation. That means you'll be pointed towards the most appropriate tariff - which in turn means your actual bills once you switch supplier will be closely in line with the quoted estimate.
No nasty surprises, just the cheaper deal you were looking for!
