A1) Real time electricity display
Real time
electricity
display
How does it work?
 Tells you how much electricity you are using in real
time in watts and £.
 Can tell you cumulative electricity costs and graph use
over time
 Uses a clip on the meter cable to measure electricity use
– in future will be remotely linked to your smart meter.
How do I get one?
 Get in touch with your energy supplier – some provide
them free with certain tariffs
 Buy one online
 In due course, they may be provided in England, Wales
and Scotland (and possibly in N Ireland) by suppliers
as part of smart metering.

A3) Smart meters
Smart meters
How does it work?
In future, gas and electricity meters will “talk” to your energy
supplier, so they can provide:
•
•
•
•
entirely accurate bills
real-time feedback when combined with a display unit
tailored energy advice and products to households;
tariffs that vary according to the time of day.
How do I get one?
 Smart meters will be rolled out in England, Wales and
Scotland (and possibly N Ireland) to all consumers by
the end of 2020, starting in a couple of years time.
 One small energy supplier already offers smart meters
with services such as on-line analysis.
5
A3) Smart meters
How much will it cost?
Will be provided free as part of the
national smart metering roll-out (likely
to start around 2012).
Could save you between 1 and 4 per
cent off your bill by enabling you to
reduce waste, and give you other services
What do I need?
Smart meters will simply replace the existing
meters in your home or outside meter cupboard,
and be installed by your supplier
Other services, such as improved bills, targeted
advice and new tariffs will be developed by
suppliers and offered to customers

A4) Cavity wall insulation
Cavity Wall
Insulation
How does it work?
 In most houses built after the 1920s,
the external walls are made of two
layers with a small air gap or 'cavity'
between them which means a
considerable amount of heat is lost
outside
 Filling the gap with an insulating
material hugely decreases the
amount of heat which escapes
through the walls and helps prevent
condensation.
How do I get it installed?
 Get in touch with the Energy Saving Trust or
your energy supplier to find a registered installer
 They survey your house, agree a quote and do the
work
7
A4) Cavity wall insulation
How much will it cost?
What do I need?
Between £200 and £500
You need to have a house that has a
cavity wall, these are properties typically
built between 1930 and 1990.
£160 per year and 400kg
CO2, if you have gas
central heating – save up to
twice this much if your
central heating is electric
It is installed for you in around 2 to 3
hours and once it is installed, you don’t
need to do anything except reap the
benefits!
8
A5) Solid wall insulation, external
External Insulation
How does it work?
 A decorative weather-proof
insulating treatment is added to the
outside of your wall.
 The insulation needs to be between
50 and 100mm thick
 Helps stop heat being lost from your
home and helps prevent
condensation
How do I get it installed?
 Get in touch with your energy supply company
or the Energy Saving Trust to find a registered
installer
 They survey your house, agree a quote and do the
work
9
A5) Solid wall insulation, external
How much will it cost?
What do I need?
Around £5,600. More
depending on your home.
Less if you are already
having work done to your
house.
The desire to save money and CO2
emissions is all you need, as well as the
finances to install it.
Save around £500 per year
on energy bills and over 2
tonnes of CO2 per year
If you are doing external renovations or
repairs it can be a perfect time to
insulate the outside walls especially as it
should save you money in the long term.
10
A6) Solid wall insulation, internal
Internal Insulation
How does it work?
 Insulation/plaster board laminates
are fitted directly to the inside of
your wall. The thicker the board the
better the insulation. They reduce
the amount of heat that would
otherwise pass through your walls
and outside
 The boards usually consist of
plasterboard backed with insulating
material with a total thickness of
90mm
How do I get it installed?
 Get in touch with your energy supply company
or the Energy Saving Trust to find a registered
installer
 They survey your house, agree a quote and do the
work
11
A6) Solid wall insulation, internal
How much will it cost?
What do I need?
Around £3,500 (more
depending on your home)

finances to get it installed.
You could save around
£470 on energy bills and
over 2 tonnes of CO2 per
year
Willingness to deal with the disruption
as it involves relocation of power sockets
and light switches. Your insulated room
will get slightly smaller, but only
external walls are done.
12
A7) Underfloor insulation
Underfloor
Insulation
How does it work?
 Timber floors can be insulated by
lifting the floorboards and laying
mineral wool insulation supported by
netting between the joists.
 You can also use a tube sealant,
such as silicon to fill gaps between
floorboards and skirting boards to
stop draughts
How do I get it installed?
 This can be an affordable DIY project and you
can get all the materials and advice you need
from your local DIY store
 Alternatively you can contact your energy
supplier for contact details of a suitable installer
13
A7) Underfloor insulation
How much will it cost?
Around £20 to seal gaps
and around £90 to insulate
the floorboards if you do it
yourself. Professional
installation will cost more.
Save around £75 on energy
bills and 200 kg of CO2 per
year if you seal gaps and
insulate your floor
What do I need?
You need to be able to access your
under-floor area, typically by lifting up
your floorboards.
This can be a DIY project therefore you
need to go to your local DIY store to
purchase the materials and get advice
Or you can pay a professional installer
14
A8) Loft insulation
Loft Insulation
How does it work?
 It acts as a blanket, trapping heat
rising from the house below. You
should also consider lagging your
pipes at the same time for optimum
efficiency
 Some properties already have some
loft insulation but you could increase
this level to the optimal 300mm to
further reduce your energy bills.
How do I get one?
 This can be an affordable DIY project and you
can get all the materials and advice you need
from your local DIY store
 Alternatively you can contact your energy
supplier for contact details of a suitable installer
15
A8) Loft insulation
How much will it cost?
Around £500.
Save from £80-£150 on
energy bills and 80+kg of
CO2 per year.
The cost and savings for
top up insulation would be
lower.
What do I need?
This can be a DIY project or you can
pay a professional installer who will do
everything for you!
You loose storage space unless you
elevate the rafters which is more hassle
In both instances you will need to empty
your loft of its contents before the
installation can be laid.
16
A9) Double glazing
Double Glazing
How does it work?
 It traps air between two panes of
glass creating an insulating barrier
that reduces heat loss, noise and
condensation
How do I get one?
 Contact your energy supplier or the Energy
Saving Trust and they can recommend a approved
installer
 They come and survey your house, agree a quote
then complete the work
17
A9) Double glazing
How much will it cost?
Greatly depends on the
size of your house, and
how many windows you
wish to fit double glazed
panes into – but expect to
pay several thousand
pounds for it. (You can
choose to only double
glaze certain windows)
What do I need?
You will need to live in a
property where you hold the
freehold and can make changes
to its external appearance.
Always look for the Energy
Saving Recommended logo
when choosing your windows
as they are the most energy
efficient
Save up to £140 on energy
bills and 720kg of CO2 per
year

A11) Ground source heat pump
Ground Source
Heat Pump
How does it work?
 Uses the energy locked in the earth of
your garden to heat your home and
hot water
 Uses a loop in the ground and a
heat pump. In the same way that
your fridge uses refrigerant to
extract heat from the inside, it
extracts heat from the ground, and
transfers it to your home

bills, and up to 1.5 tonnes of CO2 per
year
What do I need?
Large and steady demand
is needed, 12 hours a day,
7 days a week, to make it
cost effective
Must have intention of
keeping it long term as
can not always be relocated
26
A14) Solar panels to produce heat
Solar panels for hot
water
How does it work?
 Uses heat from the sun to work
alongside your conventional water
heater
How do I get one?
 Solar panels are fitted to your roof
and collect heat from the sun’s
radiation which is then used by a
heat transfer system to heat water
which is stored in your hot water
cylinder
 Get in touch with the Energy Saving Trust
(England and Wales), Action Renewables (N
Ireland) or a local installer of renewable heating
systems
 You do not need planning permission in England

30
A16) Small wind turbine
Wind turbine
How does it work?
 Uses the wind's force to rotate
aerodynamic blades that turn a rotor
which creates electricity
 There are 2 types of turbines: free
standing mast mounted turbines and
roof mounted turbines
 Most areas do not have sufficient
wind to make them effective. Mast
mounted that are taller than
surroundings buildings are best
How do I get one?
 You will need to have a
professional assessment done
to find out if the wind speed is
sufficient and you will need to
speak to your local council about
planning issues before installing
one
 Get in touch with the Energy Saving Trust
(England and Wales) or Action Renewables (N
Ireland) for details of a suitable
professional for installation
31
A16) Small wind turbine
What do I need?
How much will it cost?
Anything from £1,500 – £19,000
Not enough data to know how much CO2
and money you can save.
Roof mounted turbines are generally
thought to be poor investments. Free
standing are better
A suitable place to put the
turbine which ideally is a
smooth top hill with a flat,
clear exposure. The area
needs to be free from
excessive turbulence and
obstructions such as large
trees and buildings
An area that generates
sufficient wind speed to
ensure you receive
enough electricity
32
B1) Wind farm
Wind turbine
How does it work?
 Uses the wind's force to rotate
aerodynamic blades that turn a rotor
which creates electricity
 Works in the same way as a small
wind turbine but is much larger and
more effective. It can be used to
generate electricity for hundreds or
thousands of homes
How do I get one?
These provide power for a number of buildings in
the community.
Speak to your Local Council and start discussions
with your neighbours
33
B1) Wind farm
How much will it cost?
Costs vary depending on
the size of the system.
At present most wind farms
supply the grid directly, not
the households near them.
Some developers offer
preferential shares to the
local community or donate
one off sums, sometimes it's
a set % of income from the
wind farm.
What is needed?
Most suitable for industrial
parks, schools etc. Ideally
needs a smooth top hill
with a flat, clear exposure.
The area needs to be free
from obstructions such as
large trees and buildings
An area that generates
sufficient wind speed to
ensure you receive
enough electricity
34
B2) Small Scale Hydro
Small Scale Hydro
How does it work?
 The energy contained within water
(either potential or kinetic) is used to
turn a turbine which generates
electricity.
 There are a range of sizes and
designs from systems, from those
used in streams to community wide
systems that can provide substantial
amounts of electricity.
How do I get one?
Get in touch with the Energy Saving Trust (England
and Wales) or Action Renewables (N Ireland)
As rivers are protected in the UK, a environmental
assessment will need to be conducted on any
potential site.
 Two board categories exist: Those
that require a dam to operate, and
those that do not (run of river)
35
B2) Small Scale Hydro
What do I need?
How much will it cost?
The costs vary depending
on the size of the system
Ranging from approx. £20 25,000 for a domestic
scheme
Maintenance costs are
ongoing but normally low
Hydro plants can last for
decades.
Water – either a stream,
river or large pond, lake or
reservoir
The site should be as
close to where the
electricity is needed as
possible
An Environmental
assessment
36
B3) Community biomass boiler
Community biomass boiler
How does it work?
Suitable for community scale e.g. single
estate, block of flats, village school,
church etc.
A system operator will connect you to
the network and you will receive heat
into your central heating system - e.g.
your radiators - through a heat
exchanger.
Uses organic matter (e.g. wood chip) as
fuel to power the stoves and boilers.
The heat would be distributed via a
heat pipe / heat network
How do I get one?
Speak to your Local Council and start discussions
with your neighbours
37
B3) Community biomass boiler
How much will it cost?
You should expect free
connection and pay the
operator according to the
heat you use.
It will cost about the same
each year as buying gas
and will save around 3
tonnes of CO2 per year
What is needed?
A high-density area where
the capital cost of a heat
network is justified, best
achieved by also linking to
businesses, schools etc
You will need a normal
central heating system
with radiators etc.
The heat exchanger will
take up less space than
your boiler and hot water
tank.
38
B4) Industrial sized heat pump

How much will it cost?
What is needed?
You should expect free
connection and pay the
operator according to the
metered amount of heat
you use.
A high-density area where
the capital cost of a heat
network is justified, best
achieved by also linking to
businesses, schools etc
You should expect to pay
the same or less than you
pay for gas, and will save
around 1/2 tonne of CO2
per year
You will need a normal
central heating system
with radiators and space
to put the ground loops
The heat exchanger will
take up less space than
your boiler and hot water
tank.
40
B5) District heating with CHP plant fuelled
with either biomass or waste
How does it work?
 The surplus heat is collected tapped from
biomass or waste-fuelled CHP plant.
 A network of pipes (laid in streets like gas
pipes by a network operator) carries hot
water at 90°-110°C to provide heat to
homes, businesses and public sector
buildings.
 You connect to the network though a heat
exchanger that replaces your boiler.
 You will contract with the system operator
who will provide the heat exchanger and
meter and connects it to your existing
central heating system and takes away
your old boiler.
