About Willie Duggan

Willie Duggan was established in 1935, three generations ago, in Kilkenny, Ireland. We work with trade customers such as architects and also with general consumers who want beautiful lighting in their lives.

We have a large showroom in Hebron Business Park, Kilkenny. Opening hours: Monday to Friday 10am to 5.30pm, Saturday 9.30am to 1.30pm.

We have been selling online since 2009. In that time we’ve shipped thousands of light fittings to customers all over the world.

Products and orders

We stock a wide range of designer lighting products for residential and commercial projects. Our products are sourced from Europe’s most exclusive design brands. Our ranges are updated by our buying team each month, offering our customers a carefully chosen edit of the best lighting solutions available.

No. Due to the huge volume of items in our ranges it is not possible to stock everything we list. We usually guide 3 to 4 weeks for online orders, but if you need something faster, email us and we can see if we can get it earlier.

If you place an online order you have 24 hours in which to cancel the order. If you cancel the order after this we are liable for product and shipping costs and must legally pass these on to the purchaser.

Our standard terms and conditions are on our Terms and Conditions page.

Shipping, VAT and customs

Shipping is calculated automatically based on product type, weight and country. Please contact us if you have any queries.

No problem. Simply contact us with your query and we will respond with a price within 24 hours.

If you are within the EU we charge VAT at 23% on all orders. If you are a trade customer you should apply for a trade account and supply a relevant VAT number to qualify for the 0% VAT rate. If you reside outside the EU your order is not subject to VAT.

All customers take responsibility for their own customs and import charges.

Trade customers

We are always happy to work with interior designers, architects, engineers and specifiers to help realise their lighting solutions. Please email us and we’ll set you up with an account and partner you with one of our technical specialists.
