What I do
Breakdowns, repairs, installs and servicing, mainly across CM1 to CM14.
Boiler installs
New gas boilers fitted, across CM1 to CM14.
Servicing and repairs
Boiler servicing, breakdowns and repairs. If your heating system is at least 5 years old, it is worth having it looked at before the cold weather, when repair prices are high and waiting times are longer.
Power flushing
My specialism. Dirty, sludgy water flushed out of the radiators and pipework and the system cleansed through with clean water.
Landlord gas safety certificates
Gas safety checks and certificates for landlords and letting properties.

Power flushing, my specialism
A power flush removes the dirty, sludgy water from your heating system and then cleanses it through with clean water. The water circulates better, the radiators give out their heat again, and the boiler doesn't need to work as hard, which also saves on your gas bill.
It takes between 5 and 8 hours, depending on the condition and size of the system. I cover power flushing within 30 miles of CM1.
“It is a fact, that every winter for the past 7 years, 80% of my boiler breakdown jobs have resulted in having to Power Flush the systems. I have literally performed hundreds of Power Flushes , so you will be in good hands!”
“I was told by various different companies that I needed a new boiler. I called fm heating essex , after a recommendation. He advised me that the system had issues because of dirt and sludge in radiators and pipes, and suggested he Power Flushed the whole system
Afterwards, the difference was incredible! Radiators that never worked in years are all now working fine and the boiler is running much quieter now. Frank saved me the cost of having a new boiler- I can't thank him enough. Highly recommended!”

“Franc was very thorough in determining what the issue was. He then took time to talk me through why my heating wasn't working properly and what his next steps would be. He quickly secured the needed parts and returned to complete the job. Franc did an excellent job and it is wonderful to finally have my heating difficulties resolved. Franc is an excellent worker who is highly professional. I'd recommend him to all.”
“Fantastic job. We could not be happier. Frank went out of his way to install our new boiler in a super fast time. Frank cleaned out all the pipes and the plumbing has never worked so well. We cannot recommend Frank highly enough. Friendly honest service at a very fair price.”
