An office block near the Dominion Theatre does not get a second chance on noise. When the West End is full and the mains goes down, the last thing the building needs is a generator that sounds like a wagon parked on the roof. The brief was standby power with hush — a set that would start, take the load, and stay whisper-quiet. The machine as supplied was not that quiet. The answer was not a polite acoustic enclosure from a catalogue. We designed and built a drop-over canopy a

You do not land several tonnes of plant on a historic roof and hope the joists agree. A structural engineer was brought in to calculate the loads: the wet weight of the set, the frame, fuel in the belly tank, access steel, wind, and point loads through the existing structure. Only when those numbers were sound did we design and build a frame from I-beams to take the generator. The set sits on that frame, not on the roof covering. Going the extra mile on a job like this is not

We were not asked to quote a standard generator package. We were asked to take old chimneys off the roof of a Thames Water waste treatment plant next to the Greenwich ferry, design the replacements, get the scheme approved, crane two new stacks into position, and make the roof good again. That invitation only arrived because of the chimney systems we already design, specify and install for our own generator work. On a live Thames Water site you do not get a second chance to l

On paper it was straightforward. A 330 kVA standby generator for a building in Plaistow, East London. Concrete structure already up. Dedicated generator room already formed. An opening into that room of 2.5 m wide by 2.5 m high. Simple, you would think. It was not. The generator room was not at ground level. Worse, the only opening into it sat 2,700 mm above the finished floor. There was no loading dock, no slab-level doorway, and no crane path that could drop a complete set

Plenty of companies will sell you a generator. Fewer will take responsibility for the whole job: the load, the room, the exhaust, the changeover, the cables and the day it has to start. That is the work we do at GES Power. A standby system is not a machine on a pad. It is a chain. Get one link wrong — undersized set, contactor ATS, tails that do not match the breaker, no air, no exhaust calculation — and the chain fails on the first real cut. What we actually install New sets

We were called to a new residential development for a faulty automatic transfer switch. The panel that had failed was not a one-off oddity. It was an ATS built with non-branded imported control gear, and it was contactor-based. On a site that is still being built, that is a bad morning for everyone involved. We had to tell the client the panels do not comply with what this kind of building now needs. Why that panel was never the right product Life safety and fire-fighting sup
