Arnie's Plumbing Services Ltd - MCS Registered Installers

At Arnie’s Plumbing Services, we are proud to be MCS registered installers of air source heat pumps – a mark of quality, competence, and trust in the renewable energy industry.  As an accredited installer, we're also approved to apply for the Government's Boiler Upgrade Scheme (BUS) Grant on your behalf, giving eligible homeowners up to £7,500 off the cost of an air source heat pump installation.

The Microgeneration Certification Scheme (MCS) is a nationally recognised quality assurance scheme supported by the UK Government. It sets the standard for low-carbon energy technologies like air source heat pumps, ensuring that installations are carried out to a high and consistent standard.

Being MCS certified means we meet rigorous technical and safety standards and are regularly assessed to ensure compliance.

Choosing an MCS certified installer is essential if you’re considering an air source heat pump or other renewable technology. Here’s why:

• Access to government grants — Only MCS installers can apply for the Boiler Upgrade Scheme (BUS) on your behalf, which offers £7,500 towards the cost of a new air source heat pump.
• Peace of mind — MCS certification ensures your system is installed safely, legally, and efficiently.
• Added value — Proper certification can improve property value and future-proof your home.
• Warranty & compliance — It guarantees your equipment is eligible for manufacturer warranties and meets building regulations.

We’re not just certified — we’re highly trained, experienced, and committed to getting it right. Our team has had additional training from leading manufacturers like Vaillant and Ebac, and we're proud to be a Vaillant Master Technician. This gives us access to extended warranties on many of the systems we install - adding extra peace of mind for our customers.

We are also TrustMark registered, RECC members, and fully accredited to manage the entire process — from system design and grant application to installation and servicing. 

If you’re ready to make the switch to a low-carbon heating system with a team you can trust, we’re here to help.

Get in touch today to check your eligibility for the £7'500 Ofgem BUS Grant or to arrange a no-pressure assessment. We’ll guide you through every step — clearly, honestly, and professionally.
