THE WORLD WAR TWO PLUTO SITE THAT NEVER WAS
The Grade II listing of this small pavilion on Browns Golf Course at Sandown is based on the assumption it houses diesel engines driving generators to power WWII PLUTO pumps in the surrounding pump houses. It has now emerged that its use was purely local and there is no evidence it ever had any connection with PLUTO.

There has recently been much publicity on local plans to renovate the site, with extensive coverage in the press, TV and other media. The basis for this is Historic England's interpretation of the site as having national importance as an integral piece of PLUTO infrastructure. Unfortunately this is a rare case where Historic England have got it wrong.
Suspicions of the PLUTO claim first arose while an Island historian was researching PLUTO at The National Archives. The records covering this major project are extensive and detail virtually every aspect of the operation. Yet he found no mention of a power facility at Browns Golf Course.
The Historic England listing claims the plant was installed to serve PLUTO within the already existing pavilion, the idea being its humble appearance would disguise a wartime use. In fact the three diesel engines were installed in the pavilion when Browns was established in 1932, driving generators to provide electricity for the site. It powered two pumps to water the greens, club house lighting and ice cream making machinery. It was not uncommon for isolated businesses like Browns to generate their own DC power. The switchboard is still labelled to identify the various Browns connections.
When its true origin became clear, that might have been the end of the story. However, the idea had taken hold and it was then locally claimed the plant had been commandeered from Browns during the war to provide the power source for the pump houses. Such a concept assumes the power arrangement required to deliver fuel for the Allied advance into Europe was, coincidentally, identical to the requirements of a miniature golf course.
Had the PLUTO operation been researched at the outset, it would have revealed that the motors in the pump houses were driven by mains power, supplied by The Isle of Wight Electric Light & Power Company. The energy required to drive even one of the hugely powerful PLUTO pumps was of a different order to that provided by the pavilion. The Mather and Platt centrifugal pumps were driven by electric motors producing up to 550 bhp at 1470 rpm. Power was delivered from transformers to the pump house via high tension cables, providing three-phase current supplied at 50 cycles and 3,300 volts. They were not making ice cream.
There is no recorded power backup for the centrifugal pump houses at Sandown or Shanklin. Had a backup power facility been practical, they would have purpose built it, just as many others had been built during the war.
It is perhaps understandable that a generator house within the vicinity of the PLUTO pump houses would lead people to assume there was some connection, but the idea was pursued without any supporting evidence. The fact that the generator house had nothing to do with the PLUTO operation does not necessarily mean it has no importance as a piece of local history. It would still be worth preserving within its proper context. Whether it is of sufficient national importance to justify its Grade II listing will be something Historic England will have to review.
And now there's a movie
