AB Foods, the owner of Primark, gained 5.7 percent to 3,088 pence to be the top riser on the blue-chip FTSE 100 after it posted robust results, maintaining guidance and with a small rise in revenue.

"(The) trading update confirms the group is on track for the full year ... while there are some generally encouraging undertones we believe," Credit Suisse analysts said in a note. While they left estimates unchanged, they rate the stock as "outperform" with a target price of 3,250p.

"No change to our estimates ... but some encouraging comments here on Primark and Sugar."

Barratt Developments also rose after results, gaining 4.5 percent after Britain's biggest housebuilder said it sees better-than-expected profit for this year.

The rise partly counteracted a 5.7 percent slide in the previous session after Britain's Chancellor announced a cut in tax breaks for landlords. Barratt's chief executive said that the market reaction on Wednesday was "very overdone".

"Strong set of results from Barratt... the sector was weak after the budget yesterday but this is not anything too concerning," Guardian Stockbrokers directors, Atif Latif, said.

"The drop yesterday allowed investors to buy back into the sector and Barratt. The market continues to see the housing sector in the sweet spot of a growth area that will continue to flourish."

Other housebuilders also rebounded, with Persimmon and Taylor Wimpey both up 4.9 percent.

Elsewhere, mid-cap power producer Drax, which saw its share price slide 28 percent following Wednesday's budget, also rallied. It rose 6.8 percent after it said the changes to tax exemptions on green power would have less of an impact than some traders had feared.

The FTSE 100 rose 95 points, or 1.5 percent to 6,585.70 points by 1347 GMT, having hit a six-month low in the previous session.

Fund managers were also among top gainers, with the sector led higher by Man Group. The world's largest listed hedge fund company broke a five-day losing streak to surge about 10 percent, with traders citing positive broker comment, slightly improved performance and a recovery in commodity prices.

Miners also benefitted from a commodity price rally, with the sector buoyed by a respite in China's stock market sell-off after measures were announced to support the stability of capital markets in the world's biggest metals consumer.
