Domestic EPCs for HIP's and landlords
What is an Energy Performance Certificate?
The Energy Performance Certificate (EPC) is one of many new measures that are being applied across the EU member countries to improve energy efficiency. An EPC provides two key pieces of information.
- The energy efficiency of a property on a scale A-G (the most effecient being A and G the least efficient)
- The environmental impact of a property
It also provides recommendations of cost effective ways to improve the energy efficiency of a property. The benefit is that, if acted upon, this can mean lower energy bills due to lower energy consumption, and in turn lower carbon emissions.
When is a EPC required?
By 2009, as part of the Energy Performance of Buildings Directive (EPBD) all buildings in the UK that are constructed, sold, or rented out will be required to have a EPC.
- A new EPC is required every time the property is marketed
- Since October 2008 a landlord must provide an EPC to prospectve tenants when letting a property. The EPC is valid for ten years.
Why is an EPC important?
All EPC's on existing homes are produced using the same methodology. This means all home owners and occupiers can compare the energy efficiency of different properties - in a similar way to comparing the fuel consumption of different cars.
Part of the EPC is a recmmendation report which will list the potential rating that your house would achieve, if the changes were made. This information can be used to:
- Cut fuel bills
- improve energy performance in the home
- Help cut carbon emissions
How is a EPC Produced?
An EPC can only be produced by either a Domestic Energy Assessor (DEA) or by a Home Inspector(HI), who must be approved by either a Government approved Accreditation or Certificate scheme. The DEA will visit the perperty to assess the energy related features. These are then entered into a computer programme which is a calculation model, developed by the Government, know as RDSAP (Reduced Data Standard Assessment Procedure)
This is a cost based rating system using pre determined assumptions and therefore rates the house on its "built in" energy efficiency rather than the actual energy consumed. A DEA will also investigate:
- Property type
- Age of the property
- Type of construction
- Property dimensions
- Room and water heating systems
- Insulation levels
- Window and glazing types
- Types of lighting
These will then be passed through the RDSAP calculation and an EPC will be produced.
