Martyn O'Connor

Monima O'Connor

Office Assistant


Always ready and willing to help the office run smoothly by taking on the niggly, time-consuming tasks.

Judy Kennar

Office Manager

With the patience of a saint, she keeps all the boys in line and runs the office like a finely tuned musical instrument. She’s often seen singing on stage at the Cellar Bar.

Geoff Williams

Geoff Williams

Repairs & Maintenance Manager

Geoff’s been with Martyn since the year dot. Hugely experienced. A veritable Mr Fixit. He's been admitted by invitation into the Worshipful Company of Plumbers.

Huw Davies

Project Manager

Huw joined as an apprentice in August 2002 and completed his qualifications in 2006.

He has since completed numerous manufacturers' and accredited courses in all traditional heating systems and renewable technologies.

All great all-rounder; gets a real buzz tackling big projects across all technologies and is our in-house wood stove supremo. No job is too big.

The Team

Huw Davies


Trained as a motor mechanic originally – but is now an OFTEC qualified engineer with years of experience fixing, servicing and installing wood burners. Knows a great deal about ponies and cars.

Huw Davies


Keen fisherman in his spare time but hasn’t caught anything in years!

Josey is meticulous and real whizz at fitting bathrooms.

Ali Hussein


Ali is an apprentice. As he is over 6’4” and bigger than the rest of the Boys (fortunately ), Ali is a gentle giant.

Like the Boss, he loves cars. Mad about cars.



Expertly sails through mountains of paperwork and spreadsheets and Heather is still joyous at the end of the day.

Huw Davies


After coming for work experience during the school year, he enjoyed working with us so much he returned full time and now gained a lot of experience under his young belt.

Jan Raffour


Jan enjoys gas maintenance and repair and relaxes at home with his family after being taken for walk by his two boisterous dogs, a Caversion and a Peekapoo.



He tried clay shooting but tripped over the rifle, attempted golf but the bat swung out of his grip, then running but got bored. Now a full-time Dad to 3 children, it’s the best of all being home with his wife and kids after working hard all day for Heatshine.



Teifion has a rich, baritone singing voice (watch out Bryn !) and loves working with his Grandad on their family stock farm in Eglwyswrw, Pembs. A native Welsh speaker who is also Dilwyn’s nephew.
