And this can have an important effect on the order in which improvements should be undertaken.

​

A £12,000 heat-pump installation may appear difficult to justify.

​

Take away a £7,500 grant and the calculation becomes very different.

​

That is why APN Green Homes considers potential funding as part of the wider Green Home Blueprint.

​

Every home is different. Your green home plan should be too.

​

​

What green home grants are available?

 

As of August 2026, some of the main areas of support include:

• Boiler Upgrade Scheme funding for heat pumps

• Warm Homes: Local Grant support in England

• ECO4 support for qualifying households

• Home Energy Scotland grants and interest-free loans

• Welsh Government Nest support

• Northern Ireland energy-efficiency schemes

• EV chargepoint grants

• 0% VAT on many installed energy-saving materials

• emerging low- and zero-interest finance under the UK government's Warm Homes Plan.

​

The precise support available depends heavily on the property and homeowner. Schemes also change, so eligibility should always be checked before work is ordered.

​

​

Boiler Upgrade Scheme

 

The Boiler Upgrade Scheme, or BUS, is currently one of the most significant green-home grants available to homeowners in England and Wales.

​

Current grant levels include:

• £7,500 towards an air-to-water air source heat pump

• £7,500 towards a ground or water source heat pump

• £2,500 towards an air-to-air heat pump

• £5,000 towards an eligible biomass boiler.

​

This can make an enormous difference to the economics of changing a home's heating system.

​

​

£9,000 heat-pump grant for some off-gas properties

 

There is currently additional support for certain homes that are not connected to mains gas.

​

Until March 2027, qualifying properties heated by oil or LPG and without a mains gas connection can receive an additional £1,500 towards an eligible air-to-water or ground source heat pump.

​

That takes the grant from £7,500 to £9,000.

​

For rural homeowners facing an ageing oil or LPG heating system, this is particularly important.

​

It could mean that moving to a heat pump deserves much earlier consideration within the Green Home Blueprint.

​

​

Why the heat-pump grant changes the calculation

 

Suppose a homeowner receives a quotation of £12,000 for a suitable heat-pump installation.

​

Without a grant:

Homeowner cost: £12,000

​

With a £7,500 Boiler Upgrade Scheme grant:

Remaining cost: £4,500

​

For an eligible off-gas household receiving £9,000:

Remaining cost: £3,000

​

Those are simplified examples and actual installation costs vary, but they demonstrate why it makes little sense to decide whether a heat pump is affordable without checking the available support first.

​

The grant can fundamentally change the investment decision.

​

​

Do you apply for the Boiler Upgrade Scheme yourself?

 

The Boiler Upgrade Scheme is normally handled through the installer rather than the homeowner simply receiving cash directly.

​

The heating installation also has to meet the scheme requirements.

​

This is another reason to establish grant eligibility before committing to an installation.

​

​

Warm Homes: Local Grant

 

For eligible households in England, the Warm Homes: Local Grant can provide free energy-saving improvements.

​

The scheme applies to privately owned homes — including owner-occupied and privately rented properties — that generally have an EPC rating of D, E, F or G. Household income will usually need to be £36,000 a year or less, although other eligibility routes can include qualifying benefits or living in certain postcode areas.

​

The programme is delivered locally, so the exact improvements available and application arrangements can vary between areas.

​

​

What can the Warm Homes: Local Grant pay for?

 

The purpose of the scheme is to improve energy performance and introduce low-carbon heating where appropriate. Local delivery can therefore potentially support measures such as:

• insulation

• heating improvements

• low-carbon heating

• solar PV

• other qualifying energy-efficiency measures.

​

The government's programme is designed specifically around lower-income households living in relatively inefficient privately owned homes.

​

For an eligible household, this should be investigated before paying privately for major improvements.

​

​

Why your postcode can matter

 

Unlike a national grant with identical eligibility everywhere, some funding is distributed through local authorities.

​

That means two homeowners with similar houses and incomes can sometimes have different funding opportunities simply because they live in different areas.

​

Warm Homes: Local Grant eligibility, local delivery capacity and available funding can vary by council area. Some authorities have also experienced sufficient demand to restrict or pause new applications temporarily.

​

So one of the first questions should always be:

​

What funding is currently available at this address?

​

ECO4

 

The Energy Company Obligation, currently ECO4, focuses on improving the least energy-efficient homes and supporting households affected by fuel poverty.

​

ECO4 covers qualifying homes in energy-efficiency bands D to G and is scheduled to run until 31 December 2026 following an extension.

​

Support can involve packages of energy-efficiency improvements rather than simply one isolated technology.

​

Eligibility and delivery routes can be more complex than a straightforward grant application, and availability through energy suppliers or local-authority flexibility routes needs to be checked at the time of enquiry.

​

​

What happened to the Great British Insulation Scheme?

 

The Great British Insulation Scheme was designed primarily to help qualifying households install individual insulation measures.

​

The government's central eligibility-checking service has now closed, although GOV.UK states that some energy suppliers may still be accepting applications.

​

That is a useful reminder of how quickly green-home funding can change.

​

A grant mentioned in an article written a year ago may no longer be open in the same form today.

​

​

Scotland has a different funding system

 

Homeowners in Scotland have access to separate Scottish Government support.

​

The Home Energy Scotland Grant and Loan currently provides grants and optional interest-free loans towards qualifying clean heating and energy-efficiency improvements.

​

For qualifying heat-pump systems, homeowners can currently access up to:

£7,500 grant

​

plus

£7,500 optional interest-free loan.

​

Rural and island properties can qualify for enhanced support.

​

​

Insulation funding in Scotland

 

For qualifying energy-efficiency measures, the Home Energy Scotland scheme can provide grant funding covering up to 75% of eligible costs, subject to maximum grant levels.

​

The overall energy-efficiency grant can reach £7,500, with an additional rural uplift where applicable.

​

Individual limits apply to different improvements. Current examples include support towards:

• solid-wall insulation

• loft insulation

• cavity-wall insulation

• underfloor insulation

• heating controls.

​

The detailed funding limits and conditions should be checked before work begins.

​

​

Warmer Homes Scotland

 

Scotland also operates Warmer Homes Scotland for households struggling with energy costs.

​

Eligible households can receive energy-saving improvements worth £10,000 or more, potentially covering heating and insulation measures appropriate to the property.

​

This is distinct from the general Home Energy Scotland Grant and Loan and is targeted towards qualifying households needing greater support.

​

​

Green home grants in Wales

 

Wales operates its own Nest programme.

​

Nest provides energy advice and, for qualifying households, free energy-efficiency improvements.

​

The current Welsh scheme can potentially provide improvements including:

• insulation

• heat pumps

• solar panels.

​

Eligibility can include households receiving means-tested benefits or households meeting low-income criteria, together with property energy-efficiency requirements.

​

The Welsh Government increased funding for the programme again during 2026.

​

​

Green home funding in Northern Ireland

 

Northern Ireland has its own energy-support arrangements rather than simply following the schemes available in England.

​

The Affordable Warmth Scheme, delivered through the Northern Ireland Housing Executive, is intended to help qualifying households affected by fuel poverty and poor home energy efficiency.

​

Northern Ireland also has the Northern Ireland Sustainable Energy Programme, which has supported eligible households with measures including insulation and heating improvements.

​

Because arrangements differ significantly from Great Britain, Northern Ireland homeowners should check the current NI-specific funding position before assuming a scheme advertised elsewhere in the UK applies to them.

​

​

EV charger grants

 

There are also grants available for certain home EV charger installations.

​

From April 2026, eligible renters and people who own and live in flats can receive 75% of the cost of purchasing and installing an EV chargepoint, up to £500. Private off-street parking is required for the renter/flat-owner scheme.

​

These grants are currently scheduled to remain available until 31 March 2027.

​

​

EV grants for homes without driveways

 

A separate scheme supports eligible households relying on on-street parking where an approved cross-pavement charging solution is also being installed.

​

That scheme can currently provide 75% of eligible chargepoint costs up to £500.

​

For households without conventional driveways, this can make the transition to home EV charging considerably more practical.

​

​

Landlords can also receive EV charging support

 

Residential landlords can currently obtain grants covering 75% of eligible chargepoint purchase and installation costs up to £500 per socket, subject to scheme limits and eligibility requirements.

​

This could become increasingly relevant as landlords improve rental properties for electric-vehicle users.

​

​

0% VAT can be just as valuable as a grant

 

Not all financial support arrives as a cheque.

​

A major current benefit is the 0% VAT rate on the installation of qualifying energy-saving materials in residential accommodation.

​

The temporary zero rate currently applies until 31 March 2027, after which qualifying installations are scheduled to revert to 5% VAT under the present rules.

​

Qualifying installed technologies currently include:

• solar panels

• electrical storage batteries

• air source heat pumps

• ground source heat pumps

• water source heat pumps

• insulation

• draught stripping

• certain heating and hot-water controls

• wind and water turbines

• smart diverters.

​

For a substantial installation, that tax treatment can represent a significant saving.

​

​

Solar batteries currently benefit from 0% VAT

 

Battery storage is particularly worth highlighting.

​

Installed electrical storage batteries are currently specifically included within the government's 0% VAT treatment for qualifying residential energy-saving materials.

​

This applies whether the battery is considered alongside solar or as part of another eligible installation arrangement under the VAT rules.

​

It does not mean the battery is free or government-funded, but it reduces the effective installation cost compared with paying the standard VAT rate.

​

​

What about replacement windows?

 

This illustrates why homeowners should not assume that every energy-efficient product receives the same tax treatment.

​

The government's list of energy-saving materials qualifying for the current 0% installation rate includes insulation, solar panels, batteries and heat pumps, but ordinary replacement double glazing is not included on that list.

​

Funding and tax treatment therefore need to be assessed technology by technology.

​

​

The Warm Homes Plan is changing the funding landscape

 

The UK Government's Warm Homes Plan, launched in 2026, represents a much broader push towards upgrading British homes.

​

The plan includes direct support for lower-income households, continued heat-pump grants and a move towards government-supported low- and zero-interest finance for technologies including solar panels, batteries and heat pumps.

​

The government intends this finance to be delivered through participating lenders and potentially used for individual technologies or packages of improvements.

​

However, detailed consumer eligibility and rollout arrangements are still being developed during 2026, so homeowners should check the live position rather than assuming the finance is immediately available in every case.

​

​

Green finance could become increasingly important

 

Grants are extremely attractive, but government policy is increasingly recognising that many households do not qualify for means-tested support yet still face substantial upfront costs.

​

Low-cost finance potentially allows a household to spread the capital cost of improvements while benefiting from some of the energy savings immediately.

​

This could be particularly relevant to combinations such as:

solar + battery

​

or

​

heat pump + solar

where the upfront expenditure is significant.

​

But finance still needs to be assessed carefully.

​

An energy-saving improvement does not automatically become financially attractive simply because borrowing is available.

​

​

Green mortgages and lender incentives

 

Some mortgage lenders and financial institutions also offer green mortgage products, cashback or preferential borrowing linked to improving a property's energy performance.

​

The government's Warm Homes Plan specifically recognises the growing role of green mortgages and other finance products in helping households fund energy improvements.

​

These products vary considerably between lenders and can change frequently.

​

The correct comparison should therefore include:

• interest rate

• arrangement costs

• required EPC improvement

• repayment period

• expected energy saving.

​

​

Never start work before checking the grant conditions

 

This is extremely important.

​

Many grant schemes will not fund work retrospectively.

​

For example, Home Energy Scotland specifically states that work should not begin before a written funding offer has been issued.

​

Other schemes may require:

• an approved installer

• an EPC

• particular technology standards

• an assessment

• pre-authorisation.

​

Ordering the installation first and checking the grant afterwards can mean losing the funding completely.

​

The sensible sequence is:

Check eligibility → obtain approval → commission the work.

​

​

Do you need an EPC to obtain green home funding?

 

Sometimes.

​

Different schemes have different requirements.

​

For example, Warm Homes: Local Grant generally targets homes with EPC ratings D to G.

​

Home Energy Scotland requires a valid EPC for certain energy-efficiency funding, with the relevant measure appearing as a recommendation, although an EPC is not necessarily required there for every renewable-heating application.

​

An EPC can therefore become an important piece of evidence within the funding process.

​

But funding rules should be checked against the individual scheme.

​

​

Funding should influence the Green Home Blueprint

 

Imagine a property where several improvements are possible.

​

The homeowner is considering:

• £7,000 solar

• £5,000 battery

• £12,000 heat pump

• £3,000 insulation.

​

Without grants, the heat pump might be deferred.

​

But if the homeowner qualifies for £7,500 towards the heat pump, the priority could change completely.

​

Likewise, a household qualifying for fully funded insulation may sensibly complete that first and retain its own budget for solar.

​

This is why APN Green Homes does not simply ask:

What would you like to install?

​

We also ask:

What financial support could change the plan?

​

​

A grant does not automatically make an upgrade sensible

 

There is an important distinction.

​

Something being subsidised does not necessarily mean it is the best improvement for your home.

​

For example, a heat pump still needs:

• appropriate design

• suitable heat emitters

• adequate controls

• appropriate location

• sensible installation.

​

Likewise, funded insulation needs to be appropriate for the building.

​

The right approach is:

Determine whether the technology is suitable, then use available funding to improve the economics.

​

Not:

Install something simply because somebody will contribute towards it.

​

​

Beware of grant-led sales calls

 

Homeowners should also be cautious about unsolicited companies claiming that:

• everyone qualifies for a grant

• funding is about to disappear immediately

• the work must be ordered today

• a particular product is completely free without any eligibility checks.

​

Government-funded home-upgrade schemes have specific eligibility and delivery requirements.

​

Where possible, verify the scheme through:

• GOV.UK

• Ofgem

• your local authority

• the relevant devolved government

• recognised energy-advice services.

​

Funding should make a good project better.

​

It should not pressure homeowners into making rushed decisions.

​

​

Local councils may have additional funding

 

National schemes are only part of the picture.

​

Local authorities can sometimes offer:

• local retrofit grants

• area-based insulation programmes

• low-income energy support

• EV infrastructure programmes

• locally targeted Warm Homes funding.

​

These schemes can open and close as allocations are used.

​

That means checking the property address can be more useful than simply searching:

“What UK green home grants are available?”

​

​

Grants can change the best order of improvements

 

This is where funding connects directly with the APN Green Home philosophy.

​

Without support:

Insulation → Solar → Heat pump

might be a sensible sequence.

​

With substantial heat-pump funding:

Insulation → Heat pump → Solar

might become more appropriate.

​

Or a household receiving funded insulation might use its own available capital for:

Solar → EV charging → Battery later

​

There is no universal sequence because the funding position can be just as individual as the building itself.

​

​

Do not use a grant in isolation from future plans

Suppose a homeowner receives support towards a heat pump.

​

But they also intend to:

• build an extension

• replace floors

• install underfloor heating

• alter the roof

• add solar.

​

Those projects should ideally be considered together before work starts.

​

Otherwise, today's funded installation may need significant alteration during tomorrow's construction work.

​

A Green Home Blueprint should therefore look beyond the immediate grant deadline.

​

​

Grants for older homes

 

Older properties may qualify for many of the same programmes as newer homes, but selecting improvements can require more care.

​

Potential considerations include:

• solid-wall construction

• moisture movement

• traditional materials

• listed-building status

• conservation areas

• historic windows.

​

Funding availability should never override appropriate building design.

​

An unsuitable insulation system fitted cheaply can prove much more expensive to rectify later.

​

​

Grants for landlords

 

Landlords can also benefit from some energy-efficiency and EV schemes.

​

Warm Homes: Local Grant, for example, can include qualifying privately rented homes in England, while residential EV charging grants are available to qualifying landlords.

​

However, landlord contributions and conditions can differ from those applying to owner-occupiers.

​

​

Can grants be combined?

 

Sometimes different forms of support can contribute towards different aspects of a wider home-improvement plan.

​

But schemes often contain rules preventing the same measure being funded twice.

​

The answer therefore depends on:

• the individual grant

• the measure

• existing support

• property circumstances.

​

Never assume two grants can simply be stacked together.

​

Check the rules first.

​

​

Should you wait for a better grant?

 

That is a difficult question.

​

Government support changes regularly.

​

Waiting may produce a better scheme.

​

It could equally mean an existing scheme closes.

​

Rather than trying to predict future government policy, it is usually better to ask:

Does the project make sense using the support genuinely available today?

​

If it does, there may be little reason to delay purely in the hope that something better appears later.

​

​

Your Green Home Blueprint should contain a funding check

 

Funding is therefore not an optional extra at the end of the process.

​

It should form part of the assessment itself.

​

A well-prepared Green Home Blueprint should consider:

What does the property need?

What would the improvement cost?

What funding might be available?

What would the homeowner actually have to contribute?

What does that do to the payback?

Does the grant change which project should happen first?

​

That creates a much more useful financial picture.

​

​

Desktop Green Home Assessment

 

The APN Desktop Green Home Assessment can consider grants and funding alongside the wider home-improvement strategy.

​

The assessment can look at:

• the property

• EPC information

• existing heating

• insulation

• energy consumption

• solar potential

• batteries

• heat pumps

• EV charging

• planned construction work

• homeowner budget

• potential funding routes.

​

The objective is not simply to identify every grant with the word “green” in its title.

​

It is to establish which funding opportunities may actually be relevant to your proposed Green Home Blueprint.

​

Desktop Green Home Assessment — £495 + VAT

​

Available nationwide.

​

​

Comprehensive Green Home Survey

 

For homeowners wanting the property physically inspected before the improvement strategy is prepared, APN Green Homes also provides the Comprehensive Green Home Survey.

​

This is particularly valuable where substantial expenditure is being considered across several technologies and building improvements.

​

Comprehensive Green Home Survey — from £895 + VAT.

​

​

Check funding before spending your own money

 

The green-home funding landscape is changing quickly.

​

A household that assumes:

“There are no grants available to me”

​

may be wrong.

​

Equally, a homeowner who assumes:

“The government will pay for my green improvements”

may also be disappointed.

​

Eligibility varies enormously.

​

The important thing is to investigate properly before committing the budget.

​

A grant may allow a homeowner to bring an improvement forward several years.

​

It may free personal funds for another part of the project.

​

It may completely change the payback calculation.

​

And occasionally it may change the entire order of the Green Home Blueprint.

​

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, available funding and your future plans.

​

Understand the home. Check the funding. Create the blueprint. Then invest.

​

​
