Yes folks, all heading your way at 09.30 GMT

The first thing to bear in mind is that the first reading is comprised of only 50% of the data, and only includes the output side of the economy

So given that it was an area of deceleration/weakness during the quarter then we shouldn't be expecting much of a surprise to the upside today

Forecasts are for +0.6% qq vs +0.7% prev and +2.4% yy as prev

In their latest estimate though the NIESR sees qq +0.5% adding that the slowdown should be temporary and that "economic growth remains reasonable"

Revisions to the headline quarterly figures may be seen once the estimates of the expenditure data are available later in November from The Office for National Statistics (ONS)

The most recent official figures showed output in the construction sector was revised sharply upward during the second quarter, only to decline sharply again in July and August. Most analysts agree that this sector will most likely have a negative impact on Q3 GDP

The UK services sector, which accounts for around 78% of the total economy, slowed slightly again at the start of Q3, after it picked up in Q2 from a marked slowdown at the start of this year. According to Markit Economics, the headline PMI reading for the whole third quarter performance in the services sector slowed to the lowest level since the second quarter of 2013

Retail sales surged in September which the ONS said should add +0.1% to GDP but also warned that a major factor in the rise was the rugby World Cup currently taking place in England. So while Q3 may see a benefit it will be a temporary one and not necessarily an on-going trend into Q4.

So it's not likely to be the most bullish of releases today but that will not surprise the markets. The risk therefore will be to the topside if it's better than expected but don't expect any lasting strength in the current environment. An even weaker number and you can kiss goodbye to any BOE rate hikes for a long time

Markets will move their focus to the next set of revisions but the FOMC will be having their own impact on prices long before that

Levels to look out for on GBPUSD are 1.5300 initially then 1.5200 and of course 1.5500-10 but with 1.5400-20 prior to that on the topside. EURGBP should remain in a 0.7160-0.7260 range
