Horsham Homeowners Trust BestBuilders
Family bathroom refit in Horsham, South East. Replaced galvanised pipework with copper, new mixer fed from mains pressure. Came in £340 under quote thanks to a simpler waste route. Fitter was WaterSafe and Gas Safe registered, certificates emailed same week. Already booked them back to redo the downstairs cloakroom.
Used BestBuilders to find a bathroom fitter near Horsham. Three quotes within 24 hours, went with the firm who proposed a different layout that worked better. Day-end photographs of progress sent to my phone every working day. Final invoice came in 2% under quote.
Three months in and the wall-hung WC and basin make the whole room feel twice as big. Helped with insurance paperwork when we wanted to add the upgrade on the policy. Estate agent valued the upgrade at +£15k of property value.
