Where Should I Start Making My Home Greener?
Solar panels? Insulation? A heat pump? Battery storage? New windows? If you want to make your home greener but do not know where to start, you are not alone. The right starting point is not a particular technology — it is understanding your home.
The range of green home technology available today is remarkable.
​
A homeowner can potentially:
-
generate electricity with solar panels
-
store electricity in a home battery
-
replace fossil-fuel heating with a heat pump
-
heat and cool rooms using air-to-air systems
-
improve insulation
-
install high-performance glazing
-
recover heat through mechanical ventilation
-
charge an electric vehicle at home
-
use smart tariffs and controls to manage energy automatically.
That creates enormous opportunities.
​
It also creates a problem.
​
Where do you start?
​
The answer is different for every property.
​
That is why APN Green Homes works from one central principle:
Every home is different. Your green home plan should be too.
​
​
Do not start by choosing a product
This is probably the most important advice we can give.
​
If you begin by searching for:
solar panel installers
​
you will naturally end up discussing solar panels.
​
Search for:
heat pump installers
​
and the conversation becomes about heat pumps.
​
Speak to a window company and you will discuss windows.
​
All of those specialists can provide valuable expertise.
​
But none of those searches answers the more fundamental question:
What does my home need most?
​
That question should come first.
​
​
Start by understanding the house you already have
Before deciding how to improve a property, establish where it is starting from.
​
Consider:
-
age
-
construction
-
insulation
-
roof
-
walls
-
floors
-
windows and doors
-
heating system
-
hot water
-
ventilation
-
current energy consumption
-
electrical supply
-
available external space.
​
Then consider the people who live there.
​
Think about:
-
how many people occupy the property
-
whether someone works from home
-
when energy is normally used
-
current vehicles
-
future electric vehicles
-
plans for extensions or refurbishment
-
how long you expect to own the property
-
available budget.
​
A green-home strategy sits at the intersection of the building and the people using it.
​
​
Why every home needs a different starting point
Imagine three homeowners who each have £10,000 available.
​
Home A
A 1930s semi-detached house with:
-
poor loft insulation
-
uninsulated cavity walls
-
draughty doors
-
older heating controls.
​
The sensible starting point may be reducing heat loss.
​
Home B
A reasonably modern house with:
-
good insulation
-
modern glazing
-
efficient heating
-
an unshaded south-facing roof.
​
Solar PV may deserve priority.
​
Home C
A well-insulated property with:
-
an ageing boiler
-
good radiator system
-
plans to remain in the house for another 20 years.
​
A heat pump may deserve investigation.
​
Same budget.
​
Three very different starting points.
​
​
Step 1 – Look for obvious problems
Before installing advanced technology, deal with obvious weaknesses in the building.
​
These could include:
-
roof leaks
-
damp
-
condensation
-
defective gutters
-
poor ventilation
-
serious draughts
-
failed glazing
-
unsafe electrical installations
-
defective heating.
​
There is little sense installing £7,000 of solar panels onto a roof that needs replacing shortly afterwards.
​
Likewise, covering an unresolved damp problem with insulation can create considerably more trouble.
​
A greener home should first be a sound home.
​
​
Step 2 – Understand your energy bills
Your gas and electricity bills contain valuable information.
​
Do not just look at the amount of money paid.
​
Look at the actual kWh consumption.
​
Try to establish:
-
annual electricity use
-
annual gas use
-
other heating fuels
-
EV charging consumption
-
solar generation if already installed
-
seasonal changes.
​
Two similar houses can have dramatically different energy consumption because of:
-
occupancy
-
heating temperatures
-
working from home
-
appliances
-
electric vehicles
-
lifestyle.
​
Understanding the baseline gives you something against which future improvements can be measured.
​
​
Step 3 – Check the building fabric
The next question is:
​
How effectively does the house retain the energy you are already buying?
​
Areas worth investigating include:
-
loft insulation
-
roof insulation
-
cavity walls
-
solid walls
-
floor insulation
-
windows
-
external doors
-
unwanted draughts.
​
For some homes, improving insulation will be the obvious first investment.
​
For others, much of this work has already been completed.
​
That is why we prefer:
Understand the fabric first
​
rather than automatically:
Insulate everything first.
​
​
Should loft insulation be my first upgrade?
If the loft has little or no insulation, very possibly.
​
It can be relatively inexpensive compared with major renewable technologies and can reduce unnecessary heat loss.
​
But if the loft is already adequately insulated, spending more money there may produce little additional benefit.
​
The next pound may work harder somewhere else.
​
​
Should I replace my windows first?
Not necessarily.
​
If windows are:
-
single glazed
-
badly defective
-
extremely draughty
-
already due for replacement
​
then high-performance replacement glazing can be a sensible improvement.
​
But replacing relatively modern, serviceable double glazing purely to achieve a small improvement in thermal performance may not be the strongest financial priority.
​
Windows provide benefits beyond energy savings, including:
-
comfort
-
noise reduction
-
security
-
appearance.
​
They should therefore be considered within the overall home strategy.
​
​
Step 4 – Understand your heating system
Heating is usually one of the largest energy demands in a UK home.
​
Look at:
-
boiler or heating-system age
-
fuel type
-
efficiency
-
controls
-
radiator sizes
-
hot-water arrangements
-
heating problems
-
rooms that are difficult to heat.
​
Then ask another important question:
​
When is this system likely to need replacing?
​
That can completely change the green-home plan.
​
​
Should I install a heat pump immediately?
Not necessarily.
​
If your current boiler is relatively new and performing well, there may be stronger opportunities elsewhere.
​
You might spend the next few years:
-
improving insulation
-
upgrading controls
-
installing solar
-
preparing radiators
-
considering future plant locations.
​
Then when the existing heating reaches the end of its useful life, the house is prepared for the next technology.
​
However, if the boiler already needs replacing, investigating a heat pump now may make far more sense.
​
The best timing depends on the individual property.
​
​
Step 5 – Assess your solar potential
Once the basic building is understood, solar PV is one of the major technologies worth investigating.
​
Consider:
-
roof orientation
-
available roof area
-
shading
-
roof condition
-
planning constraints
-
current electricity demand
-
future electricity demand.
​
Solar becomes particularly interesting when a household expects to add more electrical loads over time.
​
These might include:
-
EV charging
-
heat pumps
-
electric hot water
-
air conditioning
-
home offices.
​
The house you are planning for may use considerably more electricity than the house you have today.
​
​
Should I install solar before insulation?
There is no universal answer.
​
A very poorly insulated home may have more obvious priorities first.
​
But a well-insulated property with an excellent roof may reasonably prioritise solar.
​
The important thing is that the decision is based on the property rather than a slogan.
​
​
Step 6 – Decide whether battery storage has a job to do
Battery storage can be extremely useful.
​
But it should not automatically be added because you are installing solar.
​
Ask:
What will the battery actually do?
​
Possible roles include:
-
storing surplus solar electricity
-
shifting cheap electricity into expensive tariff periods
-
supporting heat-pump demand
-
increasing solar self-consumption
-
providing limited backup where the system supports it.
​
Then consider:
​
-
battery cost
-
likely daily cycling
-
electricity tariffs
-
household consumption
-
future demand.
​
A battery should be selected because it fits the energy strategy.
​
Not because it happens to be in the installer package.
​
​
Step 7 – Think about your next car
Electric vehicles can transform the home's energy profile.
​
If you expect to buy an EV within the next few years, consider that when making decisions today.
​
It may affect:
-
solar system size
-
charger location
-
electrical capacity
-
smart tariff selection
-
battery decisions.
​
If you may eventually have two electric vehicles, think beyond the first charger.
​
The green-home plan should anticipate where the household is heading.
​
​
Step 8 – Think about summer as well as winter
Traditionally, UK home-energy advice has concentrated heavily on keeping homes warm.
​
That remains important.
​
But overheating and summer comfort are increasingly relevant.
​
Consider:
-
south- and west-facing glazing
-
loft rooms
-
highly glazed extensions
-
home offices
-
shading
-
ventilation.
​
Possible solutions could include:
-
external shading
-
blinds
-
improved ventilation
-
air conditioning
-
reversible air-to-air heat pumps.
​
A modern green home should be comfortable throughout the year.
​
​
Step 9 – Do not forget ventilation
Reducing uncontrolled air leakage can improve efficiency.
​
But homes still need controlled ventilation.
​
As insulation and airtightness improve, it becomes increasingly important to think about:
-
extract ventilation
-
trickle ventilation
-
continuous mechanical ventilation
-
decentralised systems
-
MVHR
-
heat recovery.
​
A home that uses less energy but develops condensation and poor indoor air quality has not been improved properly.
​
​
Step 10 – Look at how different technologies can work together
This is where green-home planning becomes particularly powerful.
​
Solar does not have to be considered in isolation.
​
Solar could support:
Solar + EV
​
Use home-generated electricity to help power transport.
Solar + heat pump
​
Generate some of the electricity used to heat the home.
Solar + air conditioning
​
Peak solar generation can coincide with periods when summer cooling is required.
Solar + battery
​
Store some surplus electricity for later use.
Battery + smart tariff
​
Charge when electricity is cheaper and use it when electricity costs more.
​
Heat pump + insulation
​
Reduce heating demand and then provide that heat efficiently.
​
The future green home is increasingly an integrated energy system.
​
​
Step 11 – Check grants and funding
Before fixing your budget or ordering equipment, investigate whether support is available.
​
Funding can affect the economics of:
-
heat pumps
-
insulation
-
heating improvements
-
renewable-energy measures
-
EV charging in certain circumstances.
​
Grants and schemes change over time and can depend on:
-
location
-
household circumstances
-
property type
-
technology.
​
The important principle is:
Check funding before commissioning the work, not afterwards.
​
​
Step 12 – Check planning and Building Regulations
Some green-home improvements can have regulatory implications.
​
Depending on the property and proposal, this might include:
-
solar panels
-
ground-mounted solar
-
heat pumps
-
air-conditioning equipment
-
listed buildings
-
conservation areas
-
insulation
-
replacement windows
-
electrical work
-
structural roof loading.
​
Understanding these issues early helps avoid designing a project around something that later proves difficult to obtain permission for.
​
​
What if I am planning an extension?
This can be one of the best times to create a Green Home Blueprint.
​
Building work gives you the opportunity to coordinate improvements.
​
An extension project might allow you to consider:
-
upgraded heating
-
underfloor heating
-
heat-pump preparation
-
additional insulation
-
solar
-
battery locations
-
ventilation
-
cooling
-
EV charging
-
smart controls.
​
Doing this during construction can be substantially easier than returning several years later and reopening finished walls, floors and ceilings.
​
​
What if I am replacing the roof?
Think about the green-home strategy before roofing work begins.
​
Potential opportunities include:
-
roof insulation
-
solar PV
-
solar-ready cabling
-
structural preparation.
​
It is far better to coordinate these elements than install solar and discover shortly afterwards that the roof covering requires major replacement.
​
​
What if I am renovating the whole house?
Then this is potentially the ideal moment.
​
Major refurbishment gives homeowners an unusual opportunity to reconsider:
-
heating
-
insulation
-
floors
-
windows
-
ventilation
-
electricity
-
solar
-
batteries
-
cooling
-
EV infrastructure
​
before finishes are reinstated.
​
The incremental cost of incorporating some green improvements during existing construction work can be far lower than retrofitting them later.
​
​
What should I do if my budget is limited?
Do not assume a green home requires £30,000 immediately.
​
A sensible plan can be phased.
​
Perhaps the first year's budget addresses:
-
loft insulation
-
draughts
-
heating controls.
​
The second stage might introduce:
-
solar.
​
Later:
-
heat pump
-
EV charger
-
battery storage.
​
The objective is not necessarily to complete everything immediately.
​
It is to make sure each improvement moves the property towards the same long-term objective.
​
​
Use a Now, Next and Later approach
One of the simplest ways to organise green-home improvements is to divide them into three groups.
​
Now
Work that makes sense immediately.
​
This might include:
-
repairs
-
basic insulation
-
heating controls
-
obvious draught reduction.
​
Next
Improvements that deserve preparation or investment over the next few years.
​
Potential examples include:
-
solar
-
EV charging
-
heating upgrades
-
ventilation.
​
Later
Changes linked to future events.
​
For example:
-
heat pump when the boiler needs replacing
-
battery when electricity demand increases
-
additional solar when an extension is built
-
EV charging when the next car is purchased.
​
A good plan means later does not mean forgotten.
​
It means deliberately scheduled.
​
​
Where should I spend the first £5,000?
That depends entirely on the home.
​
For one house:
insulation and controls
could offer the strongest benefit.
​
For another:
solar
might be the obvious choice.
​
For another:
air-to-air heating and cooling
could solve a genuine comfort problem.
​
For another:
the right answer may be:
keep some of the money until the existing heating requires replacement.
​
There is no universal £5,000 green-home package.
​
​
Where should I spend £10,000?
The same principle applies.
​
You might consider a combination such as:
-
insulation
-
solar
-
heating controls
-
EV charging.
​
Or the property may benefit from concentrating most of the budget on one major project.
​
What matters is not how many products you can purchase.
​
It is the improvement achieved by the total investment.
​
​
What if I have £20,000 or more to invest?
The larger the budget, the more important the planning becomes.
​
At this point, a homeowner might be considering:
-
solar
-
battery
-
heat pump
-
insulation
-
windows
-
EV charging
-
ventilation.
​
That can represent tens of thousands of pounds.
​
The danger is not necessarily buying bad products.
​
It is buying good products in the wrong order.
​
​
Good technology can still be a bad investment for the wrong house
Imagine installing an expensive battery before understanding that your solar system produces very little surplus electricity.
​
Or replacing reasonable double glazing while the loft remains poorly insulated.
​
Or installing solar immediately before reroofing.
​
Or purchasing a heat pump without adequately considering radiator requirements.
​
Every product might be technically excellent.
​
The overall strategy could still be poor.
​
That is precisely why the starting point matters.
​
​
Should I get quotes first?
Usually, it is better to understand what you are trying to achieve before collecting lots of quotations.
​
Otherwise, you may end up comparing:
-
three solar quotes
-
two heat-pump quotes
-
a battery quotation
-
an insulation quotation
​
without knowing which project should actually come first.
​
Once priorities have been established, specialist installers become extremely valuable.
​
At that stage you know what questions to ask and what you are comparing.
​
​
Where does an EPC fit?
An Energy Performance Certificate can provide useful information about a property and its theoretical energy performance.
​
But an EPC is not the same thing as a detailed Green Home Blueprint.
​
It does not normally answer the wider questions around:
-
solar and batteries working together
-
EV plans
-
air conditioning
-
future energy tariffs
-
technology sequencing
-
household budget
-
planned building work.
​
An EPC can be useful evidence.
​
It should not necessarily be the entire strategy.
​
​
Should I just copy what my neighbour has done?
Your neighbour's house may look identical.
​
That does not mean your situation is identical.
​
Perhaps they:
-
use twice as much electricity
-
own an EV
-
have different roof shading
-
have different insulation
-
work from home
-
have an older boiler.
​
Their solar-and-battery combination might be excellent for them.
​
Your best next step could be completely different.
​
Every home is different.
​
That is not simply a slogan.
​
It is a practical reason why green-home advice needs to be individual.
​
​
What are you trying to create?
This is perhaps the bigger question.
​
The objective does not have to be simply:
use less gas
​
or:
install some solar panels.
​
Instead, imagine the property you would like to own in ten years.
​
Perhaps it is:
-
highly energy efficient
-
comfortable in winter
-
comfortable in summer
-
inexpensive to run
-
generating its own electricity
-
intelligently storing energy
-
charging an electric car
-
using efficient low-carbon heating
-
automatically taking advantage of cheaper electricity tariffs.
​
Now work backwards.
​
What needs to happen to today's house to create that future home?
​
That is the beginning of a Green Home Blueprint.
​
​
APN Green Homes – creating the blueprint
APN Green Homes approaches the property as an individual project.
​
We consider:
-
where the home is now
-
its existing strengths
-
its weaknesses
-
its energy consumption
-
its potential
-
the technologies available
-
the homeowner's budget
-
future plans.
​
We then establish a practical route forward.
​
Every home is different. Your green home plan should be too.
​
APN Green Homes creates a practical blueprint for improving your home using today's energy-saving and low-carbon technologies — prioritised around your property, your budget and your future plans.
​
​
Desktop Green Home Assessment
If you know you want to improve your home but do not know where to start, the Desktop Green Home Assessment is designed for exactly that situation.
​
Using:
-
property information
-
photographs
-
EPC data where available
-
energy bills
-
floor plans where available
-
heating information
-
your future plans
-
your budget
​
we review the property and develop a practical Green Home Blueprint.
​
Recommendations can then be prioritised as:
​
Now
What deserves attention first.
​
Next
What you should plan and budget for.
​
Later
What should happen when circumstances make it worthwhile.
​
Desktop Green Home Assessment — £495 + VAT
​
Available nationwide.
​
​
Comprehensive Green Home Survey
For homeowners who want the property physically inspected, the Comprehensive Green Home Survey provides the next level of assessment.
​
This is particularly suitable where:
-
the house is older
-
construction is unusual
-
major expenditure is planned
-
several technologies need coordinating
-
a substantial renovation is proposed.
​
The on-site inspection is followed by the wider analysis needed to produce the Green Home Blueprint.
​
Comprehensive Green Home Survey — from £895 + VAT.
​
​
So, where should you start?
Do not start with solar.
​
Do not start with a heat pump.
​
Do not start with batteries.
​
Do not even automatically start with insulation.
​
Start with understanding your home.
​
Find out:
-
how it performs
-
where it wastes energy
-
what equipment is nearing replacement
-
what opportunities the property has
-
how your energy requirements may change
-
how much you want to invest.
​
Then create a plan.
​
Some improvements may happen immediately.
​
Others may happen in three years.
​
Others might wait a decade.
​
But they should all contribute towards creating the same better home.
​
Understand the home. Create the blueprint. Then invest.
​
