Llanelli Homeowners Trust BestBuilders
Loft dormer en-suite in Llanelli, South Wales. Slimline ducted MVHR added at the same time, no condensation problem since. Quote of £10360 held to the penny. Twelve-month workmanship guarantee in writing, not just verbal. Three months in and still nothing to fault.
Used BestBuilders to find a bathroom fitter near Llanelli. Three responses, all from fitters within 5 miles of Llanelli, went with the firm that quoted in writing, not just a verbal figure. Used a temporary basin and shower rig in the utility - never went a day without washing. Family of four, lived in throughout - not once felt like a building site.
Five months later, the period-correct radiator is both functional and a proper feature piece. Six-month follow-up call to ask if anything needed adjustment - nothing did. Best decision we have made on this house bar buying it.
