For years, homeowners relying on oil and LPG heating have faced a difficult choice: continue paying unpredictable fuel bills or invest thousands of pounds in a renewable heating system.
From 21 July 2026, that equation changes dramatically.
The UK Government has confirmed that the Boiler Upgrade Scheme (BUS) grant will increase to £9,000 for eligible oil and LPG-heated homes in England and Wales. For many households, this could create an opportunity to access a fully funded or significantly subsidised renewable heating system for the first time.
Official Government announcement.
This is particularly significant for rural and off-grid homeowners who have traditionally faced higher heating costs and greater exposure to fluctuating oil and LPG prices.
At Adlår Castra, we believe this is excellent news for homeowners. However, the most important conversation isn’t about the grant itself.
The funding matters. But the engineering matters more.
A heating system should provide reliable hot water, stable warmth and dependable performance for the next 15 years and beyond. Government support simply makes that level of engineering more accessible.
Most heat pump systems are assembled. This one is engineered.
What Is Changing Under the Boiler Upgrade Scheme?
The government heat pump grant available through the Boiler Upgrade Scheme has already helped thousands of households transition to low-carbon heating. Now, the Government is providing additional support specifically for off-grid homes heated by oil or LPG.
From 21 July 2026, eligible oil and LPG-heated properties can receive a £9,000 Boiler Upgrade Scheme grant towards an air source or ground source heat pump installation.
The increased funding applies to eligible:
Oil-heated homes
LPG-heated homes
Off-gas-grid properties
Air source heat pump installations
Ground source heat pump installations
Properties connected to the mains gas network will continue to qualify for the existing grant levels.
This change reflects a growing recognition that off-grid households often face higher heating costs and fewer alternatives to fossil fuel heating. Across England and Wales, around 1.7 million homes still rely on oil or LPG as their primary heating source.
For homeowners researching a Heat pump grant UK opportunity or exploring an air source heat pump grant, this represents one of the most significant funding changes since the Boiler Upgrade Scheme was introduced.
Why This Matters for Homeowners Replacing an Oil or LPG Boiler
If your home is heated by oil or LPG, you’ll already understand the challenge of managing fluctuating fuel costs.
Unlike mains gas customers, off-grid households are often exposed to sudden changes in energy prices driven by global markets, seasonal demand and supply constraints. Budgeting for heating can become difficult, particularly during colder months when fuel consumption is at its highest.
Many homeowners researching replacing an oil or LPG boiler cost focus on the price of the replacement appliance. However, the bigger question is often whether continuing to rely on fossil fuels makes sense for the next decade or more.
An oil or LPG boiler replacement may solve today’s problem.
A heat pump may solve tomorrow’s as well.
Rather than burning fuel, heat pumps transfer renewable energy from the outside air into your home. When designed and commissioned correctly, they can provide:
Consistent indoor comfort
Lower carbon emissions
Reduced dependence on fossil fuels
Improved seasonal efficiency
Greater long-term energy certainty
For many homeowners, the increased £9,000 Boiler Upgrade Scheme grant makes the transition more achievable than ever before.
Why This Is Particularly Relevant for Rural Homes
Across Surrey, Hampshire, West Sussex and neighbouring counties, many homes remain off the gas grid and rely on oil or LPG heating.
These properties often face unique challenges. Fuel deliveries must be planned in advance, storage tanks require maintenance, and heating costs can fluctuate significantly throughout the year.
Many rural homeowners are also living in larger detached or period properties and may assume that heat pumps are only suitable for newer homes.
In reality, suitability depends far more on system design than property age.
At Adlår, we regularly assess rural and off-grid homes that homeowners initially believed were unsuitable for renewable heating. Through careful design, heat loss calculations and correct system specification, many of these properties can successfully transition away from oil and LPG.
The new government heat pump grant creates an opportunity for more rural homeowners to explore renewable heating without compromising on comfort, reliability or performance.
Fully Funded Doesn’t Have To Mean Compromise
One of the biggest misconceptions in the market is that a fully funded heating system must be a basic heating system.
Unfortunately, some grant-led marketing encourages homeowners to compare installation costs without understanding what drives long-term performance.
At Adlår, we believe homeowners should compare outcomes.
Funding should improve access. It should not reduce standards.
A fully funded heating system is only valuable if it performs properly for the next 15 years.
The cheapest system is often the most expensive to live with if it delivers poor comfort, higher running costs or ongoing reliability issues.
That’s why our approach starts with engineering.
Every system is designed around:
Detailed heat loss calculations
Property-specific requirements
Radiator performance
Hot water demand
Flow temperatures
Seasonal efficiency targets
Rather than optimising for grant volume, we optimise for long-term performance.
The grant is the opportunity.
The engineering is where the value lives.
Oil Boiler Replacement vs Heat Pump Upgrade
| Consideration | New Oil/LPG Boiler | Adlår Heat Pump System |
|---|---|---|
| Government Support | None | Up to £9,000 |
| Fuel Source | Oil or LPG | Electricity |
| Fuel Price Exposure | High | Reduced |
| Carbon Emissions | Higher | Significantly Lower |
| Future Heating Strategy | Fossil Fuel Dependent | Future-Ready |
| Comfort Delivery | High-Temperature Cycling | Stable Low-Temperature Comfort |
| Long-Term Efficiency | Limited | Designed for Seasonal Efficiency |
When comparing options, it’s important to look beyond installation costs and consider comfort, future energy costs, maintenance requirements and long-term performance.
Most Heat Pump Systems Are Assembled. Adlår’s Is Engineered.
Many heat pump systems available today are effectively collections of products from multiple manufacturers assembled together during installation.
While this approach can work, it often creates complexity, fragmented support and inconsistent performance.
Adlår takes a different approach.
Our systems are designed, engineered, installed, commissioned and supported as one complete heating solution.
The difference isn’t simply technical.
It’s about accountability.
One system. One responsibility. One performance standard.
One System Shouldn’t Have To Do Two Jobs
Many conventional heat pump installations rely on a single heat pump to provide both space heating and domestic hot water.
This often creates compromises.
When the system needs to produce hot water, heating performance can be interrupted while priorities shift.
The result can include:
Fluctuating temperatures
Reduced efficiency
Increased system strain
Compromised comfort
These compromises become more noticeable during colder months when both heating and hot water demand are high.
Adlår’s Dual Heat Pump System
Adlår separates heating and hot water into two independently operating systems.
The Aurora II external unit focuses solely on space heating.
The Fjord air source heat pump cylinder is dedicated to domestic hot water production.
This allows both systems to operate without compromise, delivering:
Consistent warmth
Reliable hot water
Improved winter performance
Reduced system strain
Greater long-term efficiency
Comfort should feel stable, predictable and quietly reliable.
It should simply work.
Why System Design Matters More Than The Heat Pump Brand
When homeowners begin researching heat pumps, many focus on equipment brands.
In reality, the quality of the system design often has a far greater impact on performance than the name printed on the heat pump itself.
Most heating problems begin at the design stage.
Heat pumps reward good engineering.
Correct heat loss calculations, radiator sizing, flow temperature design and commissioning all influence how efficiently a system operates over its lifetime.
Poor design can lead to:
Higher running costs
Reduced comfort
Increased wear and tear
Lower seasonal efficiency
This is why many disappointing heat pump experiences are not technology failures.
They are design failures.
Heat pumps don’t fail homes. Poor design and rushed installations do.
This is one of the key reasons Adlår invests heavily in engineering and commissioning.
Most heat pump systems are assembled.
This one is engineered.
Replacing an Oil, LPG or Gas Boiler: Is Your Home Suitable?
One of the most common concerns we hear is:
“A heat pump won’t work in a home like mine.”
It’s a reasonable question.
Many homeowners have heard conflicting information about heat pumps, particularly when it comes to older properties, larger homes or rural locations.
The reality is that suitability should never be determined by assumptions.
It should be determined by engineering.
Our design process evaluates:
Room-by-room heat loss
Existing radiators
Pipework configuration
Insulation levels
Hot water requirements
Property layout
Many older and off-grid homes are suitable for heat pumps when the system is designed correctly.
Every home is different.
Every heating system should be too.
What Could Your Investment Look Like?
Historically, installation costs have been one of the biggest barriers to adopting renewable heating.
The increased £9,000 Boiler Upgrade Scheme grant changes that significantly.
For eligible oil and LPG households, grant support may now cover a substantial proportion of installation costs. In some circumstances, homeowners may be able to access a fully funded upgrade.
However, evaluating value solely through installation cost can be misleading.
A heating system is long-term infrastructure.
Homeowners should also consider:
Comfort consistency
Running costs
Reliability
Lifespan
Maintenance requirements
Future energy security
The grant pays for access.
Engineering protects performance.
