This will depend on the issue. However, many plumbers are also Gas Safe Registered, meaning they can undertake work on all aspects of boilers and central heating systems. It's best to look out for plumbers that display the badge of your boiler on their literature.
Clynderwen
Clynderwen is a country direct village and also community, traditionally in Carmarthenshire in Wales, yet administered as part of Pembrokeshire. It lies on the A478 Tenby to Cardigan road south of the town of Llandissilio and also north of the community of Narberth. Clunderwen, equating into English as "oak thicket", is called after an estate of the same name. On 1 April 2003, the town was moved from the administrative area of Carmarthenshire to that of Pembrokeshire, following a boundary adjustment between the counties. At the same time, a name change to Clunderwen was proposed to reflect the actual usage by the area council as well as on roadway and also other indicators.
