About Us
By law a Home Information Pack has to be available before a property can be marketed. At Roberts Hunt & Co we can process the HIP's very quickly as our partner Graham Roberts-Hunt is a qualified Domestic Energy Assessor and accredited with Elmhurst Energy. We can provide quick Energy Performance Certificates to be included in the Home Information Pack or for landlord clients that also are legally obliged to provide one to their tenants.
Energy Rating of Properties
Homes are energy rated into one of seven bands from A to G, where A is high efficiency and G is low efficiency. This is a similar system to the energy rating of domestic electrical goods and new motor vehicles. An energy rating is calculated by entering data from a survey (property dimensions, wall construction, boiler type, loft insulation etc.) into a computer program which generates an output rating on a scale from 1 to 100 (1 being a low rating and 100 a high rating). This energy rating is linked to the cost of heating, lighting, and hot water per square metre of the property. The current average rating for a property in England and Wales falls within bands D-E. New build homes built to current building standards are likely to achieve a high C or low B rating.
Two charts will be displayed in the Energy Performance Certificate. The first is an Energy Efficiency Rating and the second is an Environmental Impact Rating (based on CO2 emissions). There are small variations in the layout of these charts in England and Wales, Scotland and Northern Ireland.

Extent of Survey
The survey is non-intrusive and evidence based only. An Energy Assessor who conducts the survey will only record what can be visually inspected. Areas that are inaccessible (e.g. under the floor or within a flat roof) will be assumed to have levels of insulation commensurate with the age and type of build. If insulation has been added at a later date, then documentary evidence (e.g. builder's receipts or photographs) will be required. An Energy Assessor is not permitted to accept the word of a homeowner alone as evidence. The energy survey is not a structural survey and does not convey any information about the structural integrity or condition of the building. All heating, lighting, and plumbing systems found within the building will be assumed to be working correctly.
Access to Loft Space
An Energy Assessor should have access to loft spaces in order to measure the insulation. If the loft hatch is locked, difficult to open or has unsafe access, the Energy Assessor will not inspect this area. In circumstances such as these the software will default to the level of insulation which would have been installed at the time of build.
Heating Costs
As well as producing an energy rating for the property, the EPC will give predicted annual heating, lighting and hot water costs. These are based on a standardised occupancy (according to floor area) and a standardised heating pattern. This assumes the heating will come on from 7 am to 9 am in the morning and 5 pm to 11 pm in the evening (Monday to Friday). At the weekend it is assumed the property is heated for 16 hours per day. The default temperatures are 21°C for the main living room basis and not on the actual use of the heating system by a homeowner. For example, there may be two identical dwellings, one of which is occupied by a single person who heats only one room for a few hours of the day, and the other is home to a large family heating the whole house for most of the day. Both will obtain the same scores on the A to G scale.
The heating costs displayed are very sensitive to the type of fuel used by the heating system. Some fuels are much more expensive than others and are likely to result in a lower energy rating for the property.
Summary of the Home's Energy Performance Related Features
The EPC will contain a table giving a description of the energy efficiency and environmental performance of the walls, floor, roof, windows, main heating and main heating controls, hot water and lighting. These descriptors are based on the data input and are defaulted by the software (the Energy Assessor does not write these). For example, if the heating controls in a property comprise of a programmer only, the default descriptor would be 'Very Poor'. Most modern homes would have a programmer, room thermostat and thermostatic radiator valves, for which the descriptor would be 'Average'. A boiler energy manager or full zone control (where the temperature in different parts of the property can be controlled at different times) would be described as 'Good'.
If you would like to dicuss how the performance of your property can be improved prior to having the energy performance certificate carrried out then please contact Graham Roberts-Hunt on 020 8893 7618 or graham@robertshunt.co.uk.
