How to choose an interior designer:
– Decide exactly what rooms and ideas you have before commissioning a designer.
– Collect fabric samples, photographs and colour charts to focus your ideas.
– Ask friends and colleagues for experiences and recommendations of designers.
– The British Institute of Interior Design posts a list of members on biid.org.uk.
– Most designer offer a free first consultation, so try several to assess attitude and competency.
– Check rates (many charge circa £75 an hour, others up to 15 per cent of project cost).
– Ask whether VAT, labour, materials and project management are included in fee.
– Encourage your designer to source and buy materials (they will get trade rates).
– If you directly pay interior design labourers, budget for £500 to £1,000 per room.
– Secure a firm schedule from your designer, especially if (s)he is project managing.
