Frederik Marqeshi, Director — “If it is not good enough for my own home, it does not leave my van.”
FM Power Plumbing and Heating Ltd is an independent plumbing and heating firm, run by Frederik Marqeshi. He has spent over seven years on the tools, working for homeowners, landlords and developers across London & surrounding areas. Our company number, Gas Safe details and the boroughs we cover are on the company facts page.
We stick to one trade and do it well: boilers, central heating, hot water, underfloor heating and gas work. Tell us about the job. We survey it if needed and send you a fixed written price. The same team stays with it from the first visit to the final clean. At the end we commission the system, show you how it works and certify it.
A Gas Safe registered engineer fits and tests every gas appliance. You get the certificates by email.
Pipework routed neatly, floors protected, site cleaned. We leave your home the way we would want ours left.
You get a written price before we start. No hourly rate that keeps creeping up, and no surprise extras at the end.
“Our boiler packed in on the coldest week of the year. Frederik came out the same day, gave us a clear price and had a new combi fitted within two days. Everything was left spotless.”
James T., North London — New boiler installation
“I manage several rental properties and use FM Power for all my gas safety certificates. Always reachable, always on time, and the paperwork comes through the same day.”
Michael O., East London — Gas safety certificates (CP12)
“Megaflo system fitted in the loft and two bathrooms replumbed. Proper pressure at last. Explained every step and cleared up at the end of each day.”
Daniel R., West London — Megaflo & hot water

We work across London & surrounding areas from our base in Hayes. Each borough below has its own page. A Victorian conversion in Hackney and a 1930s semi in Harrow need very different heating, so each page says what suits the homes there.
Outside London: Essex, Kent, Surrey, Hertfordshire, Middlesex. Not sure if we cover your street? Give us a call. If we can't help, we'll tell you straight away.
It depends on the property, not on the brand. One bathroom and decent mains pressure usually points to a combi; several bathrooms running at once normally wants a system boiler and a cylinder. We tell you which fits your home and why.
Usually not. Pipe runs are planned around existing voids, joist gaps and cupboards wherever possible. Where boards do have to come up, they go back down properly.
If your mains supply is good, yes — noticeably. That is exactly why we test the flow rate first instead of promising it blind.
Not always. If a single radiator is cold, it is often air or a stuck valve, and that is a much cheaper fix. We check before selling you a flush you do not need.
Want more detail? Combi or cylinder, repair or replace, and what the law asks of a landlord are all covered in our heating guides.
Fastest way to reach us is a call or WhatsApp, we answer 24/7 — send a photo of the job and we will come back with a price. Prefer email? Use the form and we will reply as soon as we are off site.
