* Wolseley jumps after surprise, upbeat trading statement
* Defensive firms provide underlying support

LONDON, Feb 23 (Reuters) - Falling energy stocks and miners, pressured after weak German data reinforced doubts about an economic recovery, pushed Britain's top share index 0.1 percent lower by midday on Tuesday, reversing earlier gains.
By 1208 GMT the FTSE 100 <
> was 6.35 points lower at 5,345.72, retreating from a one-month high set earlier in the session. The index snapped a five-session winning run to close down 0.1 percent on Monday.German business sentiment, measured by the Ifo think-tank, fell for the first time in almost a year in February, suggesting a harsh winter may send Europe's largest economy sliding back into contraction in the first quarter. [
]"There have been a number of people looking for forward indicators to turn to show the upturn is slowing, and the German data gives support for that angle," said Tim Rees, fund manager at Insight Investments.
Energy stocks were the biggest drag on the index, pressured as crude slipped back beneath $79 a barrel <CLc1>. BG Group <BG.L>, BP <BP.L> and Tullow Oil <TLW.L> fell 0.1-1.8 percent.
Miners, firmly higher in early trade, tracked metal prices lower. Rio Tinto <RIO.L>, Xstrata <XTA.L>, Lonmin <LMI.L>, Anglo American <AAL.L> and Kazakhmys <KAZ.L> fell 0.5-1.2 percent.
Also emphasising the negative backdrop affecting the British economy, Bank of England Governor Mervyn King raised the prospect that indirect taxes or commodity prices could push up inflation, when he presented economic forecasts to legislators on Tuesday.
"The Bank of England (Governor) was relatively cautious, giving the market a reason to pause after a recent run higher," Rees at Insight said.
Investors in British and global equities also held off from taking big positions ahead of a congressional testimony by Federal Reserve Chairman Ben Bernanke later this week.
After the surprise increase last week in the rate the Fed charges banks for emergency loans, the market focus is on how Bernanke explains the move in testimony in the House of Representatives and the Senate on Wednesday and Thursday. [

WOLSELEY WOWS
Back in London, Wolseley was the standout gainer on the blue-chip index, jumping 11.8 percent and reaching its highest level in over a year, after the building materials supplier issued a surprise, upbeat trading statement. [
]Defensive stocks, which tend to fare relatively well when risk appetite retreats, were also higher.
Support services firm Serco <SRP.L> added 1.5 percent, while medical equipment firm Smith & Nephew <SN.L> was up 1.6 percent, and Associated British Foods <ABF.L> gained 1.2 percent.
But Reckitt Benckiser <RB.L> fell 0.3 percent after Britain's Office of Fair Trade said the consumer goods group may be abusing its dominant market position in the supply of heartburn medicines. [
]Reckitt was also knocked by a downgrade to 'hold' from 'buy' on valuation grounds by Panmure Gordon, which said it did not see the OFT news as being particularly material to the investment case for Reckitt.
With no significant domestic data released on Tuesday, investors will look across the Atlantic for further clues as to the pace of economic recovery. The U.S. Case-Shiller home price index is due at 1400 GMT, while U.S. consumer confidence figures will be released at 1500 GMT. (Editing by Rupert Winchester)
