Introduction
The UK’s push towards low-carbon heating has taken another step forward with a significant update to the Boiler Upgrade Scheme (BUS). As outlined in a recent communication from the Department for Energy Security & Net Zero (DESNZ), grants for certain households are set to increase to £9,000.
For homeowners, particularly those in rural or off-grid properties, this could be a major opportunity to upgrade heating systems at a reduced cost. For experienced installers like Rheams Plumbing & Heating, it reinforces the growing demand for renewable heating solutions such as heat pumps.
This blog breaks down what the announcement means and how Rheams can help you take advantage of it.
What Is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme is a government initiative designed to encourage the adoption of low-carbon heating systems. It provides upfront grants to help homeowners and small businesses replace fossil fuel heating systems with more energy-efficient alternatives.
Currently, the scheme supports installations such as:
- Air source heat pumps
- Ground source heat pumps
These systems are widely recognised for reducing carbon emissions and improving long-term energy efficiency.
What Has Changed?
The latest update introduces a proposed grant increase to £9,000, specifically targeting:
- Off-gas grid properties
- Homes currently heated by oil or LPG
- Rural households most affected by rising fuel costs
This uplift is designed to make switching to renewable heating more financially viable, especially in areas where traditional heating costs have risen sharply.
However, there are a few important points to note:
- The increase is not yet live
- Expected rollout is July 2026 (subject to confirmation)
- It applies only to this financial year
- It covers air-to-water and ground-source heat pumps only
- Biomass boilers and air-to-air systems are excluded from this uplift
Why This Matters for Homeowners
For many households, particularly those not connected to the gas grid, heating costs can be unpredictable and expensive. Oil and LPG prices have fluctuated significantly in recent years, making long-term budgeting difficult.
This increased grant could:
- Reduce the upfront cost of installing a heat pump
- Improve energy efficiency and lower running costs
- Increase property value and appeal
- Future-proof your home against further energy price volatility
For rural homeowners, this is one of the most generous incentives currently available to support the transition to greener heating.
What It Means for Rheams Plumbing & Heating
As a trusted installer, Rheams Plumbing & Heating is well-positioned to help customers navigate these changes.
While the uplift is not yet in effect, Rheams can:
- Advise on current BUS eligibility and applications
- Assess whether your property is suitable for a heat pump
- Design and install compliant heating systems
- Prepare you for the upcoming grant increase
Importantly, installers must still follow the current scheme guidance (version 4.2) until the new rules are officially implemented. Rheams stays up to date with all regulatory changes, ensuring every installation meets the latest standards.
Upcoming Changes to Be Aware Of
Alongside the proposed grant increase, additional updates to the scheme were expected to come into force on 28 April 2026.
These changes will be detailed in updated BUS guidance (version 5), which may include:
- Revised eligibility criteria
- Updated evidence requirements
- Adjustments to application processes
As these updates are confirmed, Rheams will be ready to guide customers through any new requirements.
Should You Wait or Act Now?
This is a common question, and the answer depends on your situation.
You may want to act now if:
- Your current heating system is failing or inefficient
- You want to start saving on energy bills immediately
- You qualify under the current BUS grant levels
You may consider waiting if:
- You are eligible for the higher £9,000 grant
- Your current system is still functioning well
- You want to maximise available funding
Either way, planning ahead is key. Demand for installations is likely to increase once the uplift is confirmed, which could impact availability.
