About these prices
Each price is what the supplier's website showed on the date above, including VAT, for supply only. Where an item was on offer, the normal price is shown struck through. Store prices, trade accounts and delivery charges can all differ.
To cost a whole job, add the quantity to the refurbishment budget, which uses the lowest price here as its starting figure, and add labour alongside it.
