This implies increases on the order of 10p for petrol and 16p for diesel in three weeks, continuing a broader pattern of rising prices seen since spring in response to higher crude costs and refinery margins. Brent crude has continue to trade at elevated levels in recent months amid conflict in the Middle East, supply concerns and market volatility, feeding through directly to UK wholesale petrol and diesel costs. Parliamentary and industry briefings note that the gap between petrol and diesel has widened in past months, partly reflecting strong diesel demand and tight refining capacity, which helps explain the sharper recent rise in diesel pump prices. Looking ahead through the rest of August, UK prices are likely to remain high in the absence of a sustained fall in crude or a marked strengthening of sterling against the dollar. *WelshpoolH Ballard and Son Motors, Welshpool - petrol 149.9p, diesel 168.9p- petrol 149.9p, diesel 168.9p Tesco Welshpool - petrol 153.9p, diesel 171.9p- petrol 153.9p, diesel 171.9p Hardings Sheds and Garden Supplies, Guilsfield - petrol 156.9p, diesel 178.9p- petrol 156.9p, diesel 178.9p Lewis Llandrinio - petrol 156.9, diesel 178.9p- petrol 156.9, diesel 178.9p J and M Whittingham Ltd, Llanfair Caereinion - petrol 158.9p, diesel 179.9p- petrol 158.9p, diesel 179.9p EG Welshpool - petrol 159.9p, diesel 179.9p- petrol 159.9p, diesel 179.9p Rontec Welshpool - petrol 161.9p, diesel 181.9p- petrol 161.9p, diesel 181.9p Border Garage, Welshpool - petrol (Super Unleaded only) 169.9p, diesel 181.9pNewtownGlanmule Garage, Kerry - petrol 160.9p, diesel 176.9p- petrol 160.9p, diesel 176.9p Tesco Newtown - petrol 161.9p, diesel 177.9p- petrol 161.9p, diesel 177.9p Morrisons Newtown - petrol 161.9p, diesel 178.9p- petrol 161.9p, diesel 178.9p Texaco Newtown, Llanidloes Road - petrol 161.9p, diesel 179.9p- petrol 161.9p, diesel 179.9p Rontec Newtown - petrol 162.9p, diesel 179.9p- petrol 162.9p, diesel 179.9p Texaco Caersws - petrol 163.9p, diesel 181.9pBuilth WellsCrossgates Service Station - petrol 159.7p, diesel 179.7p- petrol 159.7p, diesel 179.7p Texaco Llandrindod Wells - petrol 159.7p, diesel 179.7p- petrol 159.7p, diesel 179.7p Tesco Llandrindod Wells - petrol 153.9p, diesel 171.9p- petrol 153.9p, diesel 171.9p Esso Llandrindod Wells - petrol 161.9p, diesel 182.9p- petrol 161.9p, diesel 182.9p Asda Builth Wells - petrol 160.9p, diesel 180.9p- petrol 160.9p, diesel 180.9p Texaco Builth Wells - petrol 161.9p, diesel 179.9p- petrol 161.9p, diesel 179.9p Great House Garage, Llandrindod Wells - petrol 162.9p, diesel 180.9p*Prices correct as per the Government's Fuel Finder database at 4pm on Monday, August 3.
