Are you considering installing an outside tap for your home?

Outside taps can simplify lots of tasks like watering your garden, washing your car, or filling up a paddling pool on those hot summer days.

If you're considering hiring a professional plumber to install an outside tap, you can expect the cost to range from approximately £75 to £150. This price can vary based on factors such as your location within the UK and how accessible the area where you want to install the tap is.

In this guide, we'll break down the expenses involved —including the cost of the outside tap, additional plumbing materials you might need to budget for, and how much a plumber charges for this kind of work.

How Much to Fit an Outside Tap?

The cost to fit an outside tap, including materials and labour, is around £80 to £150. This is for a standard cold water tap, materials like pipes, fittings and insulation, and the plumber’s labour.

The price you’ll be quoted will depend on your location, the job complexity and the type of tap you choose. For example, properties with longer pipe runs or tricky plumbing layouts will incur extra costs.

Most jobs are straightforward and take 1 to 2 hours to complete. During this time, the plumber will drill through the wall, connect the tap to the water supply, fit a check valve for backflow prevention and insulate exposed pipes if necessary.

Hiring a professional means the installation meets safety and compliance standards, especially for backflow prevention. This peace of mind is worth the extra cost of a professional installation for homeowners who are not familiar with plumbing.

Does a Hot Water Outside Tap Installation Cost More?

The cost of fitting a cold water outside tap is generally lower than installing a hot water tap due to the added complexity of connecting to the hot water supply.

Here's a comparison of the typical total costs:

Type of Tap	Typical Overall Cost	Key Considerations
Cold Water Tap	£80 – £150	Simple to install, connects to the nearest cold water supply.
Hot Water Tap	£120 – £200	More complex, requires connection to the hot water system.

For most homeowners, a cold water tap suffices for general outdoor use, such as watering plants or washing cars. However, a hot water tap may be worth the extra cost if you need warm water for tasks like dog washing, filling up a paddling pool for kids, or cleaning outdoor surfaces in colder weather.

While it’s tempting to tackle an outside tap installation yourself, it can be time-consuming and risky without the right tools or expertise. Hiring a professional ensures the job is done safely and to a high standard, saving you from potential issues down the line.

How Much Does Professional Outdoor Tap Installation Cost?

The labour cost for hiring a professional to install an outside tap typically ranges between £50 and £100. The exact price depends on factors such as location, the complexity of the job, and the plumber’s experience.

Labour costs for installing an outside tap vary by location, with higher rates in London and the South East due to greater demand and living costs. Simpler installations near an existing water supply are cheaper, while jobs requiring extensive pipework or complex plumbing increase costs.

How Long Does an External Tap Installation Take?

On average, most installations take between 1-2 hours, making labour costs relatively affordable for this type of work. Plumbers may charge an hourly rate of £40 to £60, or offer a fixed price for straightforward installations.

For accurate pricing, it’s best to request quotes from multiple professionals. This allows you to compare rates and ensure you’re getting a competitive price for the work.

Who Can Install an External Tap?

A professional plumber is typically the best choice for installing an outside tap, as they have the expertise to safely connect to your home’s water supply while adhering to British Standards. Their experience ensures the installation is both functional and compliant with local regulations, giving homeowners peace of mind.

How Much Does an Outside Tap Cost?

The materials for an outside tap installation include the tap itself, copper pipes, fixtures, and connectors.

Here's a breakdown of what you can expect.

Cost of an Outside Tap

The cost of an outside tap can vary depending on the quality and design.

The table below will give you an idea of what to expect to pay for different qualities of external taps.

Type of Tap	Description	Cost Range
Budget	Basic brass tap with simple fittings.	£10 – £15
Midrange	Standard tap with added durability.	£15 – £25
Premium	High-end tap with advanced features, such as anti-freeze mechanisms or designer finishes.	£25 – £50

Midrange standard taps are the most commonly chosen option, as they offer good durability and functionality at a reasonable price.

Additional Material Costs

There are other material costs you will need to budget for, too.

The table below goes through these additional costs of installing an outside tap.

Material	Description	Cost Range
Copper Pipes	Durable piping, sold per metre.	£3 – £5 per metre
Connectors & Seals	Ensures secure connections and watertight seals.	£5 – £15
Pipe Clips	Used to secure pipes to walls or structures.	£2 – £5 per pack
Drill Bit	For creating a hole in the wall for pipework.	£5 – £15

The length of pipework needed can significantly affect the overall material cost. Copper pipes, priced at £3 to £5 per metre, are durable and reliable. However, longer distances to the water supply will increase the cost.

Most professionals typically install an outside tap near an existing water supply, such as a kitchen sink or utility room, to minimise the amount of piping that is required (and keep the cost down).

Many outside tap kits come with basic connectors and seals, offering a cost-effective solution. However, if your home requires more robust fittings, investing in higher-quality components can ensure the tap remains durable over time.

If the installation wall doesn’t already have pre-drilled access to the water supply, you’ll likely need a masonry drill bit, which typically costs £5 to £15. Preparing for these additional materials can help you avoid surprises and keep the installation process smooth.

Building Regulations and Compliance

Installing an outside tap in the UK must comply with specific building regulations to ensure safety and adherence to legal standards. While the process is generally straightforward, it’s crucial for homeowners to understand their responsibilities to avoid complications.

Backflow Prevention

One of the primary requirements for outside taps is backflow prevention. This ensures that water from the garden cannot flow back into your home’s water supply and contaminate it.

To comply with regulations, outside taps must be fitted with a double check valve or similar device. Most professional plumbers will include this as part of the installation, but it’s worth confirming.

Connection to the Water Supply

The connection to your home’s water system must meet the standards set out in the Water Supply (Water Fittings) Regulations 1999. These regulations cover everything from the type of fittings used to ensuring there are no leaks.

Using high-quality, compliant materials is essential to meeting these standards.

Freezing and Insulation

If you've got taps in areas that tend to freeze, it's a smart move to think about frost-proof taps or wrapping up those exposed pipes with some insulation. Even if it's not strictly required, doing this can save you from expensive repairs and keep everything working smoothly all year round. A little prevention goes a long way!

Additional Information

For more information, check your local water supplier’s guidelines or consult the Water Regulations Advisory Scheme (WRAS). Both resources offer comprehensive details on the legal standards for outdoor water fittings.

DIY vs Professional Installation: Which is Right for You?

When installing an outside tap, you can choose between a DIY approach or hiring a professional. Each option has its own costs and benefits, so it’s important to weigh them carefully before deciding.

Ultimately, the choice depends on your confidence in your skills, your budget, and the complexity of the installation. If in doubt, hiring a professional is often the safest option.

DIY Installation

Taking the DIY route can save you some cash, with material costs usually sitting between £30 and £80. You’ll need to pick up the tap, pipes, and a few basic plumbing tools.

The great thing is, you get to work at your own pace, so if you love getting stuck into hands-on projects, this could be a really satisfying one for you!

However, there are some drawbacks.

You’ll need basic plumbing skills to avoid leaks or water damage, and you must ensure your installation complies with local regulations, including backflow prevention requirements.

And while it can save money upfront, mistakes can be costly if you have to call a professional to fix issues later.

Professional Installation

If you’re considering hiring a professional, you can expect to spend between £100 and £200, though the exact cost can vary based on your location and the complexity of the work.

Here’s the thing: bringing in a skilled plumber can save you a lot of hassle. They’re experienced in handling tricky plumbing setups and ensuring everything complies with regulations.

Not only that, but they typically complete the job efficiently and correctly, reducing the risk of costly mistakes down the line. Many professionals also provide warranties, so if an issue crops up later, you’re covered without additional expenses.

While it might feel like the more expensive option upfront, it’s often the most dependable and time-efficient solution in the long run.

Step-by-Step Guide: How to Install an Outside Tap

An outside tap simplifies garden maintenance and outdoor cleaning, but proper planning, tools, and basic plumbing knowledge are essential.

By following these steps, you can install an outside tap effectively and safely. But if you’re unsure about any part of the process, consult a professional to avoid costly mistakes.

Tools and Materials You Need

Gather all tools and materials before starting to avoid interruptions.

Ensure your outside tap kit includes all necessary components. Double-check that you have the right drill bit for masonry walls, and plan for insulation if your area is prone to freezing temperatures.

Tools

Here are the tools required for a DIY outside tap installation:

• Adjustable spanner.

• Pipe cutter.

• Masonry drill and appropriate drill bits.

• Screwdriver.

• Tape measure.

Materials

Here are the materials required for a DIY outside tap installation:

• Outside tap kit (typically includes the tap and fittings)

• Double check valve (for backflow prevention)

• Copper pipe (or plastic, depending on your system)

• PTFE tape (to secure threads and prevent leaks)

• Insulation material (to protect against frost)

• Stopcock (for maintenance)

Step-by-Step Instructions

Installing an outside tap is a manageable DIY project if you follow these clear, step-by-step instructions.

1. Choose a Location: Select a location near the kitchen sink or another accessible water supply. Ensure minimal obstacles inside and outside the wall for easier pipe routing.

2. Turn Off the Water Supply: Shut off the water at the stopcock to avoid flooding during installation.

3. Drill Through the Wall: Using a masonry drill and the correct bit, drill a hole through the external wall for the pipe. Angle the hole slightly downward on the outside to prevent water from pooling.

4. Install the Check Valve and Tap: Attach a double check valve to the outside tap to prevent backflow into the water supply. Secure the tap to the wall using the provided fittings and use PTFE tape on the threads for a watertight seal.

5. Run the Pipes: Fit the copper (or plastic) pipe through the drilled hole. Inside, connect the pipe to the water supply using compression fittings or push-fit connectors. Ensure a tight and secure connection.

6. Fit a Stopcock: Install a stopcock inside the property along the new pipe for easy maintenance and water control.

7. Secure and Insulate: Use pipe clips to secure the external pipe to the wall. Wrap exposed pipes with insulation material to prevent freezing in colder weather.

8. Test for Leaks: Turn the water supply back on and test the tap. Check all connections for leaks and ensure the tap works as expected.

Safety Precautions and Tips

Take these essential precautions to ensure a safe and compliant outside tap installation.

• Electrical and Pipe Safety — Before drilling, check for hidden cables or pipes using a pipe and cable detector.

• Personal Protective Equipment — Wear safety goggles and gloves to protect yourself while drilling and handling tools.

• Insulation — Always insulate external pipes to prevent freezing and bursting during cold weather.

• Dry Fit Before Assembly — Measure and dry fit all components before making permanent connections to ensure proper alignment.

• Backflow Testing — After installation, test the tap for backflow prevention to confirm compliance with building regulations.

Outside Tap Alternatives

If installing an outdoor tap isn’t feasible, there are several practical alternatives to explore. These options provide a convenient way to access water outside without the cost or permanence of installing a tap.

Plus, they’re often temporary and eco-friendly solutions that might be a better fit for your needs!

Hosepipe Connectors

Hosepipe connectors attach to indoor taps, allowing you to run a hose outside without the need for permanent plumbing. They are a low-cost, easy-to-use option, especially for renters or those on a budget. A basic hose connector costs £5 to £15, depending on the brand and compatibility with your taps.

Water Butts

Water butts collect and store rainwater, providing an environmentally friendly solution for garden watering. Many come with built-in taps, eliminating the need for connection to your home’s water supply. Water butts typically cost £30 to £100, depending on size and quality.

Portable Water Pumps

For bigger gardens or tasks such as filling paddling pools, portable water pumps are a great option. They can pull water from tanks, barrels, or other containers, offering greater flexibility.

While they do require an upfront investment — typically ranging from £50 to £150, depending on their power and capacity — they can be a highly practical and versatile solution.

Tips to Save on Outside Tap Installation

Installing an outside tap doesn’t have to be expensive if you plan carefully. By making informed choices and timing your project strategically, you can save money while ensuring a quality installation.

1. Get Multiple Quotes

Always get at least three quotes from different plumbers to find the best deal. A written quote helps avoid surprise costs and should clearly outline:

• Labour fees

• Material costs

• Any additional expenses (e.g., drilling or waste removal)

Ask questions about what’s included and clarify vague terms to ensure you’re comparing like-for-like services. This approach not only saves money but also helps you hire a trusted professional.

2. Install During Off-Peak Seasons

Plumbers are often less busy during the winter or early spring, which can translate to lower rates. Booking your installation during these off-peak months not only increases your chances of getting a better price but also speeds up the scheduling process.

Plus, many plumbers run seasonal promotions, so it’s always a good idea to ask about any current deals.

3. Stick to Basic Materials

If you're looking to keep costs down while still getting great quality, sticking with standard materials is the way to go. For most homes, a basic brass tap paired with sturdy copper or plastic piping will do the job just fine. There's no need to splash out on fancy extras like premium fittings or designer taps unless you want to.

If you’re considering additional features like a water butt for eco-friendly water management, ensure it aligns with your budget and priorities to avoid overspending.

Additional Tip: Combine Jobs for Savings

If you’re planning other plumbing work, such as replacing a kitchen tap or fixing a leak, consider bundling tasks. Plumbers may offer discounts for completing multiple jobs during a single visit, saving on call-out fees and labour costs.

How Much Does it Cost to Remove an Outside Tap?

Most professionals will charge between £50 and £100 to remove an outside tap. However, the exact price you’re quoted will depend on the complexity of the installation and your location in the UK.

The process involves disconnecting the tap from the water supply, capping the pipework to prevent leaks, and sealing the wall to maintain weatherproofing.

In cases where the pipework runs a significant distance or through walls, it’ll also end up costing you more — as additional labour will be required. However, these situations are less common.

Removing an outside tap is a straightforward job for most plumbers, so it’s worth getting multiple quotes to ensure you’re not overpaying. If the tap is no longer needed, this small expense can save you from potential leaks or maintenance issues in the future.

Finding and Hiring an Outside Tap Installer

When hiring a professional to install an outside tap, it’s important to take a few key steps to ensure the job is done properly and at a fair price:

1. Check credentials. Ensure the plumber is qualified and experienced in similar jobs. Membership in recognised trade organisations or certifications can add confidence in their skills.

2. Ask about regulations. Confirm the plumber’s understanding of local regulations, particularly those regarding backflow prevention and water supply standards.

3. Review work history. Look for reviews or examples of their previous work. Positive feedback and recommendations from others are strong indicators of reliability.

4. Compare quotes. This will give you a clearer idea of the average cost and help ensure you’re not paying more than necessary. Be sure the quotes include a detailed breakdown of all expenses, such as labour and any additional materials.

5. Consider specialisation. Some plumbers or companies specialise in frost-proof taps or winterproofing solutions. If you live in a colder region, hiring someone with this expertise could be beneficial.

By taking these simple steps, you can find a reliable installer who will complete the job efficiently and to a high standard.
