Green Home Guides
Practical, independent guidance to help you understand the technologies, improvements and decisions involved in creating a greener, more efficient and more desirable home.
There has probably never been a more interesting time to improve a home.
​
Homeowners can now choose from technologies and building improvements that were either unavailable, prohibitively expensive or relatively uncommon only a generation ago.
​
Solar panels can generate electricity from the roof.
​
Home batteries can store energy for later.
​
Heat pumps can provide highly efficient heating.
​
Air-to-air heat pumps can heat and cool individual rooms.
Electric vehicles can be charged at home.
​
Smart tariffs can alter when electricity is bought.
​
Modern controls can automatically manage heating and energy consumption.
​
Improved insulation, glazing and ventilation can dramatically change how a building performs.
​
The opportunity is enormous.
​
The difficulty is understanding which of these things actually make sense for your home.
​
That is what the APN Green Home Guides are designed to help with.
​
​
Every home is different
There is no universal specification for a green home.
​
A 1930s semi-detached house may need something completely different from a modern apartment.
​
A Victorian terrace may have very different insulation opportunities from a recently constructed detached house.
​
A rural home without mains gas may have different priorities from a London property with limited external space.
​
Even two identical houses next door to each other can require different solutions because their occupants:
​
-
use different amounts of energy
-
have different budgets
-
have different heating systems
-
work different hours
-
own different vehicles
-
have different future plans.
​
That is why the philosophy behind APN Green Homes is simple:
​
Every home is different. Your green home plan should be too.
​
Our Green Home Guides help homeowners understand the individual parts of a greener home while keeping sight of the bigger picture.
​
​
Where should I start?
For many homeowners, this is the first question.
​
Should you begin with:
-
insulation?
-
solar panels?
-
a heat pump?
-
better windows?
-
battery storage?
-
an EV charger?
​
The answer depends on the property.
​
A house with very poor loft insulation may have an obvious low-cost opportunity before expensive technology is considered.
​
Another property may already be well insulated and have an excellent south-facing roof, making solar a logical next step.
​
Another may have an ageing boiler and be approaching the perfect point to consider a heat pump.
​
The best starting point is therefore not a product.
​
It is understanding the home.
​
Our Where Should I Start? guide explains how to begin assessing the property before deciding which improvements deserve priority.
​
​
Understanding your home's energy use
Before trying to reduce energy costs, it helps to understand how much energy the household actually consumes.
​
Look at:
-
annual electricity consumption
-
annual gas consumption
-
other heating fuels
-
seasonal variation
-
EV charging
-
solar generation where applicable.
​
Money alone can be misleading because energy tariffs change.
​
Consumption in kilowatt hours gives a much clearer indication of how the home is performing.
​
It also establishes a baseline against which future improvements can be compared.
​
​
Green home energy-efficiency guides
Reducing unnecessary energy consumption is one of the foundations of a greener home.
​
Our energy-efficiency guidance looks at subjects including:
-
loft insulation
-
roof insulation
-
wall insulation
-
floor insulation
-
draught reduction
-
glazing
-
heating controls
-
hot-water efficiency
-
ventilation.
​
The objective is not simply to use less energy at any cost.
​
It is to identify improvements that make the home more comfortable and efficient while representing sensible value.
​
​
Insulation guides
Insulation can be extremely effective, but different houses require different approaches.
​
Our guides consider subjects such as:
-
loft insulation
-
cavity wall insulation
-
solid wall insulation
-
internal wall insulation
-
external wall insulation
-
floor insulation
-
roof insulation.
​
Older buildings can require particular care because their construction may behave differently from modern cavity-wall properties.
​
Improving thermal performance should not create new problems with moisture or ventilation.
​
​
Solar panel guides
Solar PV is likely to remain one of the most important technologies in the transition towards increasingly electric homes.
​
Our solar guides cover questions including:
-
how solar panels work
-
solar panel costs
-
solar savings
-
solar payback periods
-
roof suitability
-
flat-roof solar
-
slate roofs
-
planning permission
-
Building Regulations
-
conservation areas
-
listed buildings
-
solar maintenance
-
ground-mounted solar.
​
But the wider question is always:
​
How does solar fit into the rest of the home?
​
A solar system could eventually help provide electricity for:
-
household appliances
-
heat pumps
-
air conditioning
-
battery storage
-
EV charging.
​
That makes future energy demand an important part of solar planning.
​
​
Solar panels and battery storage
A battery can store electricity generated by solar panels rather than immediately exporting it.
​
But that does not mean every solar installation needs a battery.
​
Battery storage makes most sense when it has a useful job to perform.
​
That could include:
-
storing daytime solar for evening use
-
charging from cheaper overnight electricity
-
supporting a heat pump
-
reducing peak-rate electricity purchases
-
increasing household use of solar generation.
​
Our battery guides look at:
-
battery costs
-
battery sizing
-
solar integration
-
tariffs
-
payback
-
usable capacity
-
future energy demand.
​
The aim is to help homeowners decide whether storage genuinely adds value to their particular energy system.
​
​
Heat pump guides
Heat pumps are an increasingly important alternative to traditional fossil-fuel heating.
​
But they are not simply a boiler that happens to be powered by electricity.
​
A successful heat-pump installation depends on several factors working together.
​
These include:
-
heat loss
-
insulation
-
radiator sizing
-
flow temperature
-
hot-water demand
-
controls
-
system design
-
electricity tariffs.
​
Our guides consider:
-
air source heat pumps
-
ground source heat pumps
-
air-to-air heat pumps
-
heat-pump costs
-
heat-pump savings
-
planning permission
-
grants
-
system suitability.
​
A heat pump may be an excellent solution for one home and a poor immediate priority for another.
​
​
Air conditioning and heating-and-cooling guides
The UK has traditionally designed homes primarily around winter heating.
​
That is changing.
​
Summer overheating can increasingly affect:
-
loft rooms
-
highly glazed extensions
-
south-facing bedrooms
-
home offices
-
upper floors.
​
Our guides explore:
-
domestic air conditioning
-
air-to-air heat pumps
-
reversible heating and cooling
-
solar-powered daytime cooling
-
planning requirements
-
efficiency
-
running costs.
​
A modern green home needs to be comfortable in summer as well as winter.
​
​
Ventilation and heat-recovery guides
Reducing heat loss is only part of creating a good building.
​
People still need fresh air.
​
As homes become better insulated and more airtight, controlled ventilation becomes increasingly important.
​
Our guides consider:
-
extract ventilation
-
continuous mechanical ventilation
-
decentralised systems
-
MVHR
-
heat recovery
-
condensation
-
indoor air quality.
​
The objective should never be simply to seal a house as tightly as possible.
​
It should be to create a home where heat and air are controlled intelligently.
​
​
EV charging guides
Electric vehicles are moving transport energy into the home.
​
That means the car increasingly becomes part of the household energy system.
​
Our EV guidance considers:
-
home EV chargers
-
installation costs
-
smart charging
-
planning permission
-
solar charging
-
battery integration
-
electrical capacity
-
future second vehicles.
​
An EV can significantly increase household electricity consumption, which means it should be considered when planning future solar and storage capacity.
​
​
Windows and glazing guides
Windows affect much more than heat loss.
​
They influence:
-
comfort
-
draughts
-
daylight
-
solar gain
-
overheating
-
ventilation
-
noise.
​
Our guidance looks at when replacement glazing may be worthwhile and when other improvements may provide better value.
​
Replacing failing single glazing can be transformational.
​
Replacing relatively recent double glazing purely for a small thermal improvement may be much harder to justify financially.
​
Again, the condition of the individual home matters.
​
​
Smart heating and energy controls
One of the biggest changes in modern homes is the ability to control energy intelligently.
​
Smart technology can potentially manage:
-
heating
-
individual rooms
-
hot water
-
EV charging
-
batteries
-
solar generation
-
electricity tariffs.
​
The future home may increasingly decide automatically when electricity should be:
-
purchased
-
generated
-
stored
-
consumed
-
exported.
​
Our smart-energy guides explore how these technologies can work together.
​
​
Green home costs
Cost is understandably one of the biggest homeowner concerns.
​
Our guides look at typical costs for improvements including:
-
solar
-
batteries
-
heat pumps
-
air conditioning
-
insulation
-
EV charging
-
glazing.
​
But headline prices tell only part of the story.
​
The important questions include:
​
What does it cost?
​
What might it save?
​
How long might it last?
​
Is grant support available?
​
Would some of the expenditure have been necessary anyway?
​
That last question can make an enormous difference.
​
If a boiler needs replacing regardless, the economics of choosing a heat pump are very different from replacing a nearly new boiler.
​
​
Green home savings and payback
Some green improvements can repay their cost relatively quickly.
​
Others provide a much longer financial return.
​
Some may never make sense if assessed only through energy-bill savings but could still be worthwhile for:
-
comfort
-
property condition
-
convenience
-
resilience
-
reduced carbon emissions.
​
Our payback guidance helps homeowners compare different improvements realistically rather than assuming the most expensive technology must provide the greatest return.
​
​
Green home improvements by budget
Not everyone has £20,000 or £30,000 available.
​
Nor does every home require that level of investment.
​
Our Best Green Home Upgrades for Your Budget guide looks at what might be achievable with different levels of expenditure.
​
A relatively modest budget could sometimes provide surprisingly valuable improvements.
​
The important thing is to ask:
How far can this budget move my particular home?
​
rather than:
Which product can I buy for this amount?
​
​
Grants and funding
Government and local funding can substantially affect the economics of certain green-home improvements.
​
Schemes can change, and eligibility may depend on:
-
location
-
household circumstances
-
existing heating
-
property type
-
technology.
​
Our guides explain the main types of support homeowners should investigate before committing to substantial expenditure.
​
The key principle is:
Check potential funding before ordering the work.
​
​
Planning permission guides
Many green-home improvements can be carried out without a full planning application.
​
Others may require permission depending upon:
-
location
-
equipment
-
building type
-
property designation
-
installation position.
​
Our planning guides cover subjects including:
-
solar-panel planning permission
-
heat-pump planning permission
-
air-conditioning planning permission
-
EV charger planning permission
-
listed buildings
-
conservation areas.
​
Understanding planning requirements early can prevent wasted design work and unexpected delays.
​
​
Building Regulations guides
Planning permission and Building Regulations are not the same thing.
​
A project may not need planning permission but can still involve Building Regulations.
​
Our guidance looks at regulatory considerations associated with:
-
solar panels
-
structural roof loading
-
insulation
-
heating
-
ventilation
-
glazing
-
electrical work.
​
The exact requirements depend on the proposed work.
​
​
Listed buildings and conservation areas
Older and protected buildings often require a more sensitive approach.
​
The challenge is to improve energy performance without damaging:
-
historic fabric
-
architectural character
-
traditional construction.
​
Our heritage guidance considers technologies such as:
-
solar panels
-
heat pumps
-
insulation
-
replacement windows
-
external equipment.
​
For these properties, careful design can be just as important as the technology itself.
​
​
Green home guides for extensions and renovations
Extensions and major renovations provide an excellent opportunity to think beyond the immediate building project.
​
Before construction begins, homeowners can consider:
-
insulation
-
heating
-
underfloor heating
-
solar
-
batteries
-
ventilation
-
cooling
-
EV charging
-
smart controls.
​
It is often far easier to provide cables, ducts, pipework and plant space while construction is underway than retrofit them once everything has been decorated.
​
A building project can therefore become the first stage of a much broader Green Home Blueprint.
​
​
Green home guides for older houses
Older homes can have enormous potential, but they can also require greater care.
​
Their construction may include:
-
solid walls
-
suspended timber floors
-
traditional roofs
-
historic windows
-
breathable materials.
​
Modern improvements should respect how the existing building works.
​
A solution appropriate for a modern cavity-wall house may not automatically be suitable for a Victorian or Edwardian property.
​
Our guidance aims to help homeowners understand these differences before commissioning work.
​
​
Think about the home you will need in ten years
Green-home planning should not be based solely on today.
​
Your energy requirements may change substantially.
​
Today you might have:
-
gas heating
-
petrol car
-
low electricity demand.
​
Within ten years you could have:
-
heat pump
-
electric vehicle
-
solar panels
-
battery storage
-
electric cooling.
​
That could completely change the way the property uses electricity.
​
The best Green Home Blueprint therefore considers the direction in which the household is travelling.
​
​
Green technology should work together
One of the central themes throughout our Green Home Guides is integration.
​
Instead of thinking about:
​
solar
battery
heat pump
EV
​
as separate products, consider:
Solar + EV charging
Solar + heat pump
Solar + battery
Battery + smart tariff
Heat pump + insulation
Solar + daytime cooling
Ventilation + improved airtightness
​
Each technology can affect the value and performance of another.
​
This is where whole-home planning becomes particularly important.
​
​
Do not mistake more technology for a greener home
A house containing every available green technology is not automatically a well-designed green home.
​
Sometimes the best decision is not to install something.
​
A battery may not yet make financial sense.
​
Windows may not need replacing.
​
The existing boiler may still have years of useful service.
​
Additional wall insulation may provide little benefit.
​
Good advice should be willing to say:
Not yet.
​
That can be every bit as valuable as recommending immediate investment.
​
​
Create a Green Home Blueprint
The purpose of our guides is to help homeowners become better informed.
​
But when several technologies and building improvements need to be considered together, the next stage is creating an individual plan.
​
APN Green Homes calls this the Green Home Blueprint.
​
It considers:
-
the existing property
-
current energy consumption
-
building fabric
-
heating
-
renewable-energy opportunities
-
energy storage
-
ventilation
-
cooling
-
EV requirements
-
available budget
-
grants
-
planned building work
-
future household requirements.
​
The result is a practical route towards improving the property over time.
​
​
A Now, Next and Later strategy
Not every improvement has to happen immediately.
​
A Green Home Blueprint can divide recommendations into:
​
Now
Improvements that make sense today.
​
Next
Work to prepare, coordinate or budget for.
​
Later
Changes that should be considered when:
-
the boiler needs replacing
-
the roof needs renewing
-
an extension is built
-
an EV is purchased
-
household energy requirements change.
​
This avoids unnecessary expenditure while ensuring today's decisions do not make tomorrow's improvements more difficult.
​
​

​
Comprehensive Green Home Survey
For homeowners who want the property physically inspected, APN Green Homes offers the Comprehensive Green Home Survey.
​
The on-site assessment allows us to examine the property directly before completing the wider review and developing the Green Home Blueprint.
​
This can be particularly useful for:
-
older properties
-
complex buildings
-
unusual construction
-
substantial refurbishment
-
homeowners considering major investment.
​
Comprehensive Green Home Survey — from £895 + VAT.
​
​
Use our Green Home Guides to understand your options
The purpose of the APN Green Home Guides is not to convince every homeowner to install every available technology.
​
It is to help you understand:
-
what each improvement does
-
what it costs
-
where it works
-
where it may not work
-
how technologies interact
-
what permissions may be required
-
where each measure could fit within a wider plan.
​
The technology available to homeowners today is extraordinary.
​
Used intelligently, it can help create homes that are:
-
more comfortable
-
less wasteful
-
cheaper to operate
-
better prepared for changing energy markets
-
ready for electric transport
-
capable of generating and managing their own electricity
-
more desirable for the future.
​
But the technology should serve the home.
​
The home should not be redesigned around whichever technology happens to be fashionable.
​
​
Every home is different. Your green home plan should be too.
That principle sits behind every APN Green Home Guide.
​
A truly greener home begins by understanding:
the building
the people who live in it
the energy they use
the budget available
​
and
​
where they want the property to be in the future.
​
From there, the available technologies become tools for creating a better home rather than isolated products to purchase.
​
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.
​
Understand the home. Create the blueprint. Then invest.
​
​
NEXT STEPS
Every home is different, so the right next step depends on your property, your budget and what you want to achieve. APN Green Homes can help you turn the information you have just read into a practical plan for your own home. Whether you are considering one improvement or looking at a complete whole-home energy upgrade, we can help you understand what is suitable, what should be prioritised and where your money is likely to make the greatest difference.
