Source: Sero cost and comparison summary Aspen Grove 2023

Smart meter data has been analysed for all homes and data has been used for 26 homes including 20 3-bedroom homes, 4 2-bedroom and 2 4-bedroom homes. Using the actual smart meter consumption data, the unoccupied months have been estimated using an estimated monthly consumption profile. The electricity import data for 26 homes has been used, where no more than 35% of the annual energy demand has been estimated. All homes with a higher level of estimated data than this have been excluded. For export, the data is more limited due to some late MPAN registrations and a large proportion of move-in dates occurring after the peak solar production months.

Using the limited data available, the estimated consumption suggests a typical home will spend £97 per month, or £1,170 per year. This is 49% cheaper than a traditional new build (with a gas central system) and 60% cheaper than an average UK typical home. All costs for comparison are based on the current Octopus Flexible (Standard Variable) single rate energy tariff (rates correct as of 1st January 2023). Energy pricing is improving and so is the availability of Time of Use (TOU) energy tariffs & Sero anticipate these costs and the scale of reductions can be improved further by optimising batteries and heating/hot water against off-peak rates.

How It Works

1

Solar energy is harvested from the sun

Solar photovoltaic (PV) panels use cells containing a semiconductor material to capture the sun’s energy and convert solar radiation into electricity.

2

The energy is stored in a battery

The electricity is stored in a battery installed in your home. When additional electricity is needed to top up the battery it can be drawn from the grid during low-cost/low carbon periods, and excess electricity can be sold back to the grid at high-cost/high carbon periods.

3

The energy is used to power your home

The electricity will be used to power your home as normal (i.e. keep the lights on) but can also be used to charge an electric car via the charging points located on your external wall. The energy is controlled by a smart home energy management system called ‘The BEE', which monitors your home’s energy needs to optimise the distribution of energy within your home.

4

Heat is generated via a ground source heat pump

Heat (for both hot water and central heating) is generated via a ground source heat pump (which runs on electricity), connected to a system of deep underground boreholes.

5

The stored heat is distributed around the home

You have a hot water tank connected to the heat pump to store hot water for showers or washing up.

6

Minimising heat loss

As well as the groundbreaking new energy and heat harvesting technologies, we further ensure that the carbon footprint of your home is minimised through insulation at all possible points of heat loss.
