A boiler is usually the priciest single item on the quote, so a proper discount here does more for the margin than anywhere else on the job. We compare live discounted prices on combi, system and heat-only boilers alongside flue kits, extensions and plume management from UK trade suppliers, biggest saving first. Flue components are brand-specific, so match the kit to the boiler before it goes on the order.
Affiliate links: we may earn a commission when you buy through our links at no extra cost to you. We refresh prices from supplier feeds every day. Suppliers can still change a price after that, so check the final price before you buy.
