Highlights
"High praise as always for all the team at London Efficiency. My booking was promptly and courteously taken and as always the engineer David arrived on time. He carried out a thorough service of my boiler including checking all my radiators and running the hot taps. He worked carefully and neatly and donned plastic overshoes and left my flat even tidier than before! Thanks London Efficiency! GW Kew"
"Great Job! The engineer identified the problem by completing a CCTV Looksee, very friendly and professional, couldn't be happier/ highly recommend."
"The London Efficiency Team are the best. They gave great advice and ended up jetting the drain! They left the area very clean afterwards and disinfected the whole area afterwards. Couldn't be more happy!"
