Curzon, the specialist heating spares supplier, is opening two more branches, taking the total branch network to 37.
Both Sheffield and Abingdon branches aim to provide customers with access to more than 75,000 products including spares for boilers from UK's leading manufacturers.
The decision to open two more branches is part of Curzon's expansion programme for 2009, with more launches planned for the second half of the year.
The new branches have been integrated into existing Graham depots.
Debbie-Sue Price, marketing manager at Curzon, said: 'The opening of the Abingdon and Sheffield branches sends out a positive message in what is currently a negative economic climate and we're delighted to be in a position to be able to continue with our expansion programme.'
