Great job by the guys at J M Brewer, this time on a renovation project, installing a 14kW Mitsubishi heat pump and pre-plumbed cylinder.

We supplied the kit and sorted the system design, MCS certification and paperwork through our MCS Umbrella Scheme, leaving the team to get on with the installation.

If you’re a plumber thinking about getting into heat pumps but don’t have your own MCS accreditation, give us a shout.

Heat pump replacement complete 👌

Out with the old, in with the new!

Our customer was having a few issues with their old ground source heat pump, so we sorted them out with a brand new Viessmann Vitocal 200-G. Nice work by the lads at Tomaknock Services 👏

Commissioned and ready to go! 👌

We’ve been working with Richard at RP Plumbing and Heating Services on this Samsung heat pump installation.

We sorted all the BUS grant paperwork for Richard, so he could get on with the job without having to worry about it.

On the subject of the BUS grant, we now bankroll up to £9,000 upfront, so you don’t have to pay that amount out of your own pocket and wait to get it back.

If that would make life a bit easier for you and your next install, get in touch and have a chat with us.

A few weeks on from this installation by one of our regular installers, Squires Heating Services Ltd. 👏

We supplied a 14kW Mitsubishi heat pump and pre-plumbed cylinder, and our engineer Martin attended site to get this bad boy commissioned and ready for the colder months!

If you’re a plumber who wants to start fitting heat pumps but doesn’t fancy the paperwork and certification headache, this is exactly what our umbrella scheme is for.

Get in touch to find out more.

Sircar Builders Ltd have been working with us since the early days of Alto, so it’s great to see them delivering a couple more projects with us over the last month or so!

They’ve installed a Mitsubishi Ecodan on this self-build project, with a 210L hot water cylinder and a mix of radiators and underfloor heating.

Nice work, guys!
