Frequently Asked Questions

Everything you need to know about the Boiler Upgrade Scheme, heat pumps, and working with C12 Ltd.

What is the Boiler Upgrade Scheme?

The Boiler Upgrade Scheme (BUS) is a UK government initiative providing £7,500 grants to help businesses and homeowners switch from fossil fuel heating to low-carbon heat pumps. The scheme aims to decarbonize heating and reduce carbon emissions.

Who is eligible for the grant?

Eligible properties must be in England or Wales, have a valid EPC, not be new builds or social housing, and currently use electric, oil, LPG, or coal heating. The property owner must consent to the installation.

How much does a heat pump installation cost?

With the £7,500 BUS grant and C12 Ltd (c12-energy.co.uk), eligible businesses can get a completely free heat pump installation. The grant covers the entire cost of the system and professional MCS-certified installation.

How efficient are heat pumps compared to electric heating?

Heat pumps are up to 400% efficient — for every 1kW of electricity they use, they produce 4kW of heat. This compares to 100% efficiency for electric heaters, meaning you can save up to 75% on heating bills.

How long does the installation take?

Most residential and small commercial heat pump installations are completed in 3-5 days. This includes removing the old system, installing the heat pump, and commissioning the system.

Do I need planning permission?

Most heat pump installations fall under permitted development rights and don't require planning permission. However, some properties (listed buildings, conservation areas) may need permission. We'll advise you during the survey.

What maintenance do heat pumps require?

Heat pumps require minimal maintenance — typically an annual service check similar to a boiler. They're designed to be reliable and long-lasting, with most systems lasting 15-20 years with proper maintenance.

Can heat pumps work in winter?

Yes! Modern air source heat pumps work efficiently even in temperatures as low as -15°C. They extract heat from the outside air year-round and are designed for the UK climate.

What if my business is not eligible for the BUS grant?

We can still provide a quote for a heat pump installation without the grant. Additionally, there may be other funding schemes or financing options available. Contact us to discuss your specific situation.

How do I apply?

Simply complete our online eligibility check form. We'll review your application, arrange a free site survey if you're eligible, and guide you through the entire process from application to installation.

What standard of installation can I expect?

Every C12 Energy installation meets the highest industry standards. You receive: a 2-year comprehensive workmanship warranty, an MCS Certificate issued on completion, a manufacturer's warranty (typically 5 years), a completed DNO (Distribution Network Operator) application, and electrical work notified to your local authority building control. All work is carried out by fully qualified, MCS-certified engineers.

What documentation will I receive after installation?

On completion you will receive a full documentation pack including your MCS Certificate, manufacturer warranty documents, electrical installation certificate (BS7671 compliant), building regulations compliance certificate, DNO application confirmation, a heat pump instructions manual, and a handover and commissioning report.
