How much does it cost to repair a dripping tap?

A leaking tap might seem like a small nuisance, but it can waste a surprising amount of water and increase your bills over time. In fact, according to Water UK, a dripping tap wastes at least 5,500 litres of water each year. ^[1]

The cost to repair a leaking tap will vary depending on a few things, but the cause of the leak will usually be the biggest factor. On average, you'll find it will cost anywhere from £50 and £150 (inc VAT) for a plumber to fix a leaking tap. Repairs usually take between just 30 minutes to around 2 hours - of course depending on the severity and complexity of the leak at hand.

Simple leaks from worn washers are quick and cheap to fix. However, if the issue lies with a damaged cartridge, ceramic disc, or valve body - which are common in modern taps - the repair becomes more complex and costly. 

How much do the materials cost? 

The cost of parts to fix a leaking tap will depend on the type of tap and the exact component that needs replacing. Basic washers or O-rings can cost as little as £2 to £5, while cartridge replacements or valve kits typically range from £10 to £50.

Your plumber may either supply these parts as part of their service or you can provide them yourself if you prefer. Just bear in mind that your plumber may charge an additional 20 - 25% on top of the cost of the parts, to cover their time and travel.

What other factors affect the cost of repairing a dripping tap? 

There are often a few other factors that will affect the cost of repairing a dripping tap, such as the type of tap in question, whether you book with an independent plumber, and when you book. 

1. Type of tap

Basic pillar taps (often found in bathrooms) are usually the easiest and cheapest to fix, often just needing a washer replacement. Kitchen mixer taps and modern monobloc taps are more complex, typically using cartridges or ceramic discs that require more time and expertise to repair. Outdoor taps are generally simple, but corrosion or poor access can complicate the job. High-end or designer taps may also need specialist parts or tools, which can add to the cost.

2. Who you book with

Sole traders will usually charge a cheaper rate than more established tradesperson services. However, these larger companies will typically come with better perks, such as greater variety of slots, the ease of an online booking form and a responsive customer service team at hand if anything were to go wrong. Larger tradesperson services will also usually have plumbers on standby, ready to cover in the case of illness or unforeseen absence on the day. 

3. When you book

Depending on the extent of the leak, you may need a plumber to come out on the day. Be aware that emergency or out-of-hours call-outs (evenings, weekends, bank holidays) will typically be charged at a premium.

What causes a dripping tap?

There are several reasons why a tap might start leaking from high water pressure to a worn washer. Here's a breakdown of the most common below. 

Is it more cost efficient to replace a dripping tap? 

While many leaking taps can be repaired, replacement is sometimes the more cost-effective option. If your tap continues to leak despite multiple repairs, or if it has a cracked body, corroded components, or fittings that no longer stay secure, replacing it may be the smarter long-term choice. Older or designer taps can also be expensive to fix if replacement parts are difficult to source.

Upgrading to a new tap can also improve water efficiency and help prevent future issues - which can help you save money on your water bill over time.

Your plumber can advise you on the best course of action. If a replacement is the recommended option, they can handle everything from sourcing a suitable tap to completing the installation.

Can I fix a dripping tap myself?

If you have basic DIY skills, fixing a dripping tap can sometimes be as simple as replacing a washer or tightening a loose part. However, if you’re unsure about what’s causing the leak or uncomfortable working with plumbing, it’s best to hire a professional. Incorrect repairs can cause further damage which may end up costing you more in the long run.

A professional plumber will come equipped with the hands on experience to correctly diagnose the core cause of the leak and fix it. Most professionals also offer a 72 hour guarantee, meaning they’ll return to fix it any issues free of charge.
