Every business we list is phoned and checked first, so towns fill up one at a time. Many businesses based nearby already cover Portland: try the trade you need across Dorset.
Portland is in the Dorset Council area, so planning applications and building control go through Dorset Council.
Portland stone is still quarried here, and many of the island's older buildings are built from it.
The centre of Portland is in a conservation area, and there are 84 listed buildings within a kilometre of the centre. In a conservation area the work you can do without planning permission is more limited, so check before changing windows, doors, roofs or front boundaries. Listed buildings need listed building consent for most changes, inside and out.
Some land within a kilometre of the centre of Portland is in Flood Zone 3, the Environment Agency's highest flood risk category, from the sea. Check the flood risk for your address before major ground-floor work, and ask about flood-resilient options when you replace floors, kitchens or electrics.
Close to the sea, salt air and wind are hard on metal fixings, window hardware and paintwork, so ask tradespeople about materials and finishes suited to coastal homes.
