What is MCS Accreditation? How can the Boiler Upgrade Scheme help you afford an Air Source Heat Pump!

When it comes to upgrading the heating system in your home, choosing the right installer is just as important as choosing the right heating technology. If you’re considering an Air Source Heat Pump (ASHP), you may have seen the term MCS Certified mentioned and heard about the government’s Boiler Upgrade Scheme (BUS) grant.

But what does it all mean — and how does it help you save money?

At RH Parker Ltd, we’re proud to be MCS accredited, which means we’re able to help our customers access the BUS grant and install renewable heating systems to the highest standard. Here’s a clear breakdown of how it all works.

 What Is MCS Accreditation?

MCS (Microgeneration Certification Scheme) is a nationally recognised quality assurance scheme for renewable heating and energy systems. For an installer to be MCS certified, they must meet strict technical standards in design, installation, and customer care.

In simple terms, MCS accreditation means:

  • Your heat pump is designed correctly for your home

  • It is installed to high industry standards

  • The system will deliver the performance and efficiency you expect

  • Your installation qualifies for government funding

Choosing an MCS-accredited installer protects you as a customer and ensures your system is safe, efficient, and built to last.


What Is the Boiler Upgrade Scheme (BUS)?

The Boiler Upgrade Scheme is a government grant designed to encourage homeowners to switch from fossil fuel heating (gas, oil, LPG, or electric) to low-carbon systems like air source heat pumps.

If eligible, you can receive a grant of up to £7,500 toward the cost of installing an air source heat pump.

This grant is applied directly to the installation cost, making heat pumps significantly more affordable.


Are You Eligible for the BUS Grant?

You can usually apply if:

  • Your property is in England or Wales

  • You currently heat your home with oil, LPG, gas, electric, or a solid-fuel boiler

  • You’re replacing your existing system (or installing low carbon heating in a new build you own)

There are a few simple checks we carry out (such as insulation levels) before applying, and we handle the application on your behalf.


How Much Does It Reduce The Cost?

The BUS grant provides:

£7,500 off the cost of an Air Source Heat Pump installation

This brings the price much closer to the cost of a new oil or LPG boiler — but with much lower running costs and future-proof performance.


Why Choose an Air Source Heat Pump?

Air Source Heat Pumps are:

  • Highly efficient (up to 3–4x more efficient than boilers)

  • Cheaper to run than oil or LPG in most homes

  • Low carbon, helping reduce your home’s emissions

  • Future-ready, as the UK transitions away from fossil fuels

  • Long-lasting, with service life of 20+ years
