LONDON (MarketWatch) -- U.K. stocks rose Monday, though energy shares on the resource-heavy FTSE 100 benchmark pared gains as oil prices began losing ground.

The FTSE 100 rose 0.5% to 6,576.74, as consumer goods, industrial and financial stocks advanced.

Kingfisher shares were among the best performers on the benchmark, rising 1.7% after the home-improvement retailer agreed to sell its 70% stake in B&Q China to Wumei Holdings for 140 million pounds ($219 million).

Oil majors Royal Dutch Shell PLC and BP PLC picked up 1% and 0.2%, respectively, though were off higher levels of the session. Oil stocks have been hit hard in recent weeks, as oil prices tumbled to five-year lows on oversupply concerns in the industry.

Oil prices had found some relief earlier in the day, but selling pressure later picked up pace. West Texas Intermediate (CLG5) futures swung 2% lower, below $56 a barrel. Brent futures slipped below $60 a barrel.

After starting at the top of the benchmark, shares of Tullow Oil PLC finished 4.1% lower.

Also lower, Tesco PLC shares lost 2.4%. The U.K.'s Financial Reporting Council said Monday it has launched an investigation into the supermarket chain's accounts for the 2012, 2013 and 2014 fiscal years, following the recent accounting debacle.

Overall trading volumes will be lighter than usual this week. The market will be closed on Thursday and Friday for Christmas and Boxing Day.

The FTSE 100 last week climbed 3.9%, marking its best week in more than three years, according to FactSet data.
