Boiler Upgrade Scheme

How the government helps
reduce your cost

The Boiler Upgrade Scheme is a UK government programme designed to help homeowners switch from fossil fuel heating to cleaner alternatives. Here's what it means for you — in plain English, not government language.

Starting point
From £1,500
Net cost after grant applied
A significantly reduced upfront cost
The BUS grant is applied directly at installation by Sailax, reducing what you pay on the day. For eligible homeowners, the net cost is far more manageable than the full system price.
Standard BUS grant
Up to £7,500
For eligible installations
The standard Boiler Upgrade Scheme grant
Available to eligible owner-occupiers replacing a qualifying heating system with a heat pump. Sailax guides you through eligibility and the full BUS application process.
Oil / LPG homes only
Up to £9,000
Higher support — eligible properties only
Enhanced grant for oil or LPG homes
If your home is currently heated by oil or LPG, you may qualify for a higher level of BUS support. Eligibility is confirmed as part of your initial assessment.
Important to know: Grant eligibility depends on your property type, current heating system, and EPC rating. Sailax will confirm exactly what applies to your situation during your no-obligation enquiry — you're under no pressure to proceed.

Why it matters who installs it

Not every heat pump installer approaches residential projects the same way.

Some homeowners have had poor experiences — rushed installations, missed grant details, and little support after the job is done. Sailax was built around a more considered approach.

What some installers do
✕Quote without a proper home assessment
✕Miss grant eligibility details that reduce your cost
✕Recommend systems not suited to the property
✕Offer little support or communication after installation
✕Rush through projects to maximise volume
What Sailax does
✓Complete a proper home assessment before quoting
✓Identify all grant eligibility — maximising what you save
✓Design the right system for your property's requirements
✓Stay accessible throughout and after installation
✓Take time to get the installation right, every time
Benefits of switching

Why homeowners are choosing heat pumps

Beyond the grant, there are lasting reasons to make the switch — for your home, your bills, and the long term.

Significant Energy Savings

Heat pumps typically operate at 300–400% efficiency, producing three to four times more energy than they consume — dramatically reducing your heating bills.

Works in Most UK Homes

Modern heat pumps work reliably in the UK climate and across a wide range of property types — from newer builds to older homes with the right setup.

Low Maintenance

Heat pumps are designed for reliability with minimal servicing requirements — and no annual gas safety checks to arrange once you've made the switch.

Heating and Hot Water

A single system handles both space heating and domestic hot water — replacing your boiler and cylinder in one efficient unit.

Lower Carbon Emissions

Switching from oil or gas to a heat pump significantly reduces your home's carbon footprint — and becomes cleaner as the electricity grid continues to decarbonise.

Long-Term Asset Value

With fossil fuel boilers being phased out, heat pumps are the forward-compatible choice — potentially adding value to your property as the market shifts.

Common questions

Everything UK homeowners ask
before making an enquiry

The Boiler Upgrade Scheme (BUS) is a UK government programme providing grants to homeowners who replace fossil fuel heating systems with low-carbon alternatives such as heat pumps. The grant is applied directly by the installer — reducing your upfront cost. You don't receive the money yourself; it comes off the total installation price.
Eligibility depends on several factors: you need to own the property, have a valid Energy Performance Certificate, and be replacing a fossil fuel heating system. When you enquire with Sailax, we work through your eligibility in plain English during our initial consultation — with no obligation to proceed.
The level of BUS grant support depends on what you're replacing. The higher amount — up to £9,000 — is specifically for homes currently heated by oil or LPG. Properties replacing gas or other systems may qualify for a different level of support. Sailax will confirm exactly what applies to your situation during your initial consultation.
It's a genuine figure — for homeowners who qualify for the maximum BUS grant support, the net cost after the grant can be around £1,500 or more depending on the total installation cost and system required. It does depend on your eligibility. We'll always give you an honest, accurate picture of the numbers that apply to your specific situation before you commit to anything.
A typical residential heat pump installation in the UK costs between £7,000 and £14,000 before grant support. With the Boiler Upgrade Scheme applied, eligible homeowners can reduce this substantially. The exact cost depends on your property size, current setup, and the system required — which is why we complete a proper assessment before quoting.
Most residential heat pump installations are completed within 2 to 4 days. The exact time depends on your property, the system installed, and whether any additional work is needed — such as radiator upgrades or pipework changes. We give you a clear, realistic timeline during the assessment.
Yes — this is a core part of our service. We guide you through the Boiler Upgrade Scheme process from start to finish, handle the necessary paperwork, and ensure the grant is correctly applied to your installation cost. You won't need to navigate the scheme administration yourself.
Heat pumps work well in a wide range of UK homes, from modern builds to older properties. Older homes may benefit from insulation improvements to maximise efficiency, but this doesn't automatically rule them out. During your home assessment, we'll evaluate your property honestly and tell you whether a heat pump is the right choice — and what, if anything, needs to be addressed first.
