We love shopping with this award-winning retailer as not only are they a highly-rated plumber’s merchant and specialist distributor, they also offer incredible trade prices and mega deals, allowing customers to save on everything from copper tubing to towel rails. We especially love how easy they make it to shop on a budget with free delivery and click and collect options, plus clearance offers and weekly best buys.

I recently purchased a new double-panelled radiator, exclusive to City Plumbing, at a discounted rate and saved a further 10% off with a City Plumbing voucher code that I received for signing up for the newsletter. I paid for my radiator in 3 instalments and also benefited from free delivery to my home as I spent over £75.

Shop in the offers section

The offers section is the best place to shop for a discount, with savings of up to 50% on everything from radiators to boilers.

• Not only are there over 300 price drops and top deals and offers each day, but you can also find limited-time promotions, free gifts and discounts on selected brands and products.

Check out the clearance

For further discounts, the City Plumbing clearance section is ideal.

• The clearance section offers huge savings on end-of-line products for both collection and delivery.
• All of these items come with customer reviews and ratings of 1-5 stars, so you know which are of the best quality.
• Many clearance items can also be used alongside app first-order codes, newsletter welcome discounts and free delivery.

Earn rewards on every order

Sign up for the City Plumbing rewards programme and earn award points on every purchase.

• You can then use these points to redeem exciting rewards such as TVs, smart watches, gift vouchers and even holidays! Or, you can use them as credit against your City Plumbing account to save money on future purchases.
• You can even earn double points on exclusive brands and unbranded spares, plus you’ll get perks thrown in like free delivery and discounted days out.
• You’ll also get access to exclusive offers, monthly prize draws and social giveaways.

Sign up for a discount

Sign up for the City Plumbing newsletter and get access to exclusive offers and news.

• Members of the mailing list also get 10% off their first order, so it’s well worth signing up if you’re a new customer.

Download the City Plumbing app

A great way to save money on your first order is to sign up for the City Plumbing app. When you download the app, you’ll get 15% off your first order with the exclusive in-app code.

Use the spares finder

You can save money by avoiding splashing out on brand-new products and buying spare parts instead. City Plumbing offers over 20,000 spare parts on their website - just use their Spares Finder to find them. You can enjoy next-day delivery and click and collect on spares, plus every so often, they offer free delivery on spares with a flash code.

Utilise the boiler pack builder

If you’re unsure about which boiler is best for your home, use the boiler pack builder to build the ideal device. Select everything from your fuel type and boiler type to brand and heat output, and get the right boiler for your individual space. Not only will this save you money on the initial cost of your boiler, but it’ll also reduce heating bills down the line.

Enjoy trade deals

You can save up to 80% off selected products with the trade deals at City Plumbing. Register for a trade account or log in to get access to the latest exclusive trade prices and trade deals. You’ll also get free delivery on your trade orders and can earn points towards future orders and rewards.

You can discover new, lower prices on bestselling City Plumbing radiators, plus plenty of ways to save on everything from central heating radiators and designer radiators to column radiators and towel rails. Shop by colour or size and find the right radiator for each room in your home, plus save money on your order with a City Plumbing discount code.

There are plenty of other ways to save money, too - simply download the app and make an account for 15% off your first order, or sign up for the newsletter for 10% off on the City Plumbing website. There are also loads of deals on radiators in the offers section and even bigger savings in the clearance. What’s more, when you spend £75 or more, you’ll get free UK delivery on your radiator, or you can select the click and collect option and pick up your order from a branch at a time that suits you.

City Plumbing also offers seasonal offers and discounts on Stelrad and Halcyon radiators, so keep an eye out for these on their homepage or in our deals section above. Remember, you can also enjoy flexible payment options, and you can earn points on every order when you sign up for a rewards account.
