Boiler Servicing

The Boiler Upgrade Scheme (BUS) enables homeowners and small property owners in England and Wales to reduce the upfront cost of installing low-carbon heating systems. Eligible applicants can receive grants of up to £7,500 for air source and ground source heat pumps, while biomass boiler installations may qualify for a £5,000 grant.
By partnering with HDE (UK) LTD—proudly serving customers across the UK since 2010—and using an MCS-certified installer, the application process is handled on your behalf, with the grant deducted directly from the installation cost. Extended through 2028, the BUS makes it easier and more affordable to embrace sustainable heating, lower energy bills, and reduce your property’s carbon footprint.

Applying for the Boiler Upgrade Scheme (BUS) is simple, especially with the support of HDE (UK) LTD, which has been delivering trusted heating solutions throughout the UK since 2010.
1. Choose an MCS-Certified Installer: Partner with an MCS-certified provider such as HDE (UK) LTD, proudly serving customers across the UK since 2010. Your installer will guide you through the entire process and handle the necessary paperwork.
2. Receive a Property Assessment and Quotation: The installer will assess your property, recommend a suitable low-carbon heating system, provide a detailed quotation, and confirm your eligibility for the scheme.
3. Grant Application Submission: Once you approve the proposal, the installer submits the Boiler Upgrade Scheme application to Ofgem on your behalf, so there is no need for you to complete any forms.
4. Grant Deduction: If approved, the grant—currently up to £7,500 for eligible heat pump installations—is deducted directly from the installation cost, reducing your upfront investment.
5. Final Confirmation and Installation: Ofgem will contact you to confirm that you wish to proceed. After confirmation, the installation can begin, allowing you to enjoy an efficient, environmentally friendly heating system with confidence.

Air Source Heat Pumps (ASHPs) are an energy-efficient way to heat your home by extracting heat from the outside air and transferring it indoors, even during cold weather. Modern ASHPs continue to operate effectively in temperatures as low as –15°C, making them well suited to the UK climate. With more than a decade of experience serving customers across the UK since 2010,
HDE (UK) LTD installs high-performance systems that can deliver three to four units of heat for every unit of electricity consumed, helping to reduce both energy bills and carbon emissions. For optimal performance, professional installation and good home insulation are essential, ensuring reliable, year-round comfort and efficiency.

The cost of running a heat pump depends on a few things, like the type of system, the size of your home, and local electricity rates. In general, Air Source Heat Pumps (ASHPs) are cheaper to install but might cost a little more to run than Ground Source Heat Pumps (GSHPs), especially when it’s really cold, as ASHPs have to work harder.
On average, you can expect an ASHP to cost between £500 to £1,000 per year to run, while a GSHP may cost between £400 and £700 per year, thanks to its higher efficiency. That said, both options can lead to big savings on your energy bills compared to traditional gas or oil heating, particularly if your home is well insulated.
The running costs are also influenced by the coefficient of performance (COP), which measures how efficiently your heat pump converts electricity into heat. The better the insulation and the more efficient the system, the more you’ll save in the long run.

The primary difference between Air Source Heat Pumps (ASHPs) and Ground Source Heat Pumps (GSHPs) lies in their heat source. ASHPs extract heat from the outside air and are typically simpler and more affordable to install, making them a popular option for many UK homes. GSHPs, by contrast, harness heat stored in the ground via buried pipework, offering exceptional efficiency and consistent performance, particularly during colder weather, though they require more space and a greater initial investment.
Since 2010, HDE (UK) LTD has been helping customers across the UK select and install the heat pump system best suited to their property, enabling them to enjoy reliable comfort while reducing energy use and carbon emissions.

When comparing Air Source Heat Pumps (ASHPs) with traditional boilers, the key distinction lies in how they generate heat. ASHPs extract renewable heat from the outside air and transfer it indoors, whereas gas and oil boilers produce heat by burning fuel. As a result, heat pumps are significantly more efficient, often delivering three to four units of heat for every unit of electricity consumed.
In well-insulated homes, they can also offer lower running costs and substantially reduce carbon emissions, particularly when powered by renewable electricity. Boilers generally have a lower initial installation cost, but they typically incur higher fuel expenses and a greater environmental impact over time.
Since 2010, HDE (UK) LTD has been helping homeowners across the UK choose and install heating solutions that balance comfort, efficiency, and sustainability for their individual needs.

The main difference between air-to-water and air-to-air heat pumps lies in how they deliver heat. Air-to-water systems extract heat from the outside air and transfer it to water, providing space heating through radiators or underfloor heating as well as domestic hot water.
They are particularly well suited to properties with existing wet central-heating systems. Air-to-air heat pumps, by contrast, deliver warm air directly into the home through indoor units and can often provide cooling during summer, making them an excellent choice for homes without radiators. Both technologies are highly efficient: air-to-water systems offer the added benefit of hot water production,
while air-to-air units are generally simpler and less expensive to install. Since 2010, HDE (UK) LTD has been helping customers throughout the UK select the heat pump solution that best matches their property, comfort requirements, and energy goals.

Heat pumps, particularly Air Source Heat Pumps (ASHPs), do produce some sound, primarily from the outdoor fan and compressor unit. Typical operating noise levels range from approximately 40 to 60 decibels, comparable to a modern refrigerator or gentle rainfall, although the exact level varies by model, installation quality, and placement.
Modern ASHPs are engineered for quiet operation and are usually positioned away from bedrooms and living spaces to minimise disturbance. Ground Source Heat Pumps (GSHPs) are generally even quieter, as much of their equipment is located underground or indoors.
Since 2010, HDE (UK) LTD has been designing and installing heat pump systems throughout the UK with careful attention to siting and compliance with all applicable noise regulations, ensuring efficient and unobtrusive performance for homeowners.
