How Much to Fit an Outside Tap?

Having an outside tap can have many benefits as an outside water source means that you can easily water your garden, plus, you can attach a hose or pressure washer as needed.

If you have a water supply quite close to an outside wall, installing an outside tap can be a relatively simple job.

The cost of an outdoor tap alone is usually on average between £6-£10. Provided you are within a metre distance from your main water supply, then the cost for materials is usually around £14-£20.

The cost for a plumber to fit the outside tap is usually an average of between £80-£150 – This price will usually include the cost of the tap and materials.

If your kitchen is at the front of the house, does that make it trickier to fit an outside tap at the rear?

Labour Costs and Timescales

As with any project with external contractors, get at least 3 quotes and try to view their past work if possible. Make sure you communicate your design ideas clearly, but do listen to the contractor’s ideas too, as their experience will help to make your vision practical.

Depending on where you are in the UK, the labour costs for hiring a plumber to install an outside tap can vary. However, plumbers will usually charge on average somewhere between £150-£270 per day.

The cost that you can expect to pay for labour will depend a lot on the type of job that you are looking for. The harder the job, the more you can expect to pay in labour as the job will most likely take a lot longer.

Some more difficult jobs may also need more than one labourer to complete the job, so again this would result in the overall labour costs being more.

Your location in the UK can also affect the cost of labour. To hire a plumber in London may cost you around £20-£60 more per day than if you were to hire a plumber in the North of the UK.

Supply Only Costs

The cost of an outdoor tap alone is usually on average between £6-£10.

Provided you are within a metre distance from your main water supply, then the cost for materials is usually around £14-£20.

You can also purchase outside tap kits. An outdoor tap kit comes complete with a tap plus everything you need to install it. These garden tap kits usually cost on average around £20-£30.

The cost for the supplies only is only a fraction of the cost of the entire job. You will see from the prices above that the majority of the cost of installing an outside tap lies in the costs of the labour to install it.

Additional Costs

There are a number of additional costs that you may need to consider when it comes to having an outside tap installed. These costs can include the following:

  • Garden Waste Removal – £100-£200

Cost Factors of Installing an Outside Tap

There are a number of cost factors that you may need to think about when installing an outside tap. Below is a list of things that may affect your outside tap cost.

Location of Tap

Where you want the tap to be installed can affect the overall cost of the installation. Installing the tap on the wall where the main water pipe runs through is considerably less than having it installed somewhere else.

The cost to have it installed on the kitchen sink wall is on average around £80-£150 whereas the cost to have it installed on a different wall is around £180-£250. To have an outside tap installed at the bottom of the garden costs quite a bit more, prices for this usually start at around £300+.

Location of Property

Your location within the UK can affect the cost of your outside tap installation. Labour costs in London are considerably more than in the North of the UK.

With this in mind, the labour costs can really bump up the overall price of an outside tap installation cost for those living in London.


Extensive Plumbing Work

If there is extensive plumbing work needed to install the outdoor tap, this will end up costing more. As you can imagine, extensive plumbing work will increase the time of the job by quite a bit. The longer the job takes to complete, the more you can expect to pay in labour costs, and so the overall cost can really add up.

What's Involved in Installing an Outside Tap?

Below is a guide on everything that is involved in fitting an outside tap.


There are a few requirements that you need to be aware of before installing an outdoor tap. The installation needs to comply with some certain regulations that specify the following:

  • The tap needs to be capable of being isolated by means of an in-line shut-off valve. This can be such as a stopcock or an in-line service valve.
  • A device needs to be installed in the pipework to stop the water from being drawn back into the household water supply if a negative water pressure happens to be created. The usual device that’s fitted to sort this problem out is a double check valve which works by incorporating two spring loaded non-return valves. Sometimes the outside tap itself will have this type of valve within it already.
  • Provisions must be made to drain the water away from the pipework during the winter months when the tap won’t be in use.
  • The external pipework must be fitted with thermal insulation materials as necessary.
  • The pipework and tap must be electrically earthed. This ensures that the tap can’t become electrically dangerous.

Installing the Pipework for an Outside Tap

The following steps need to be taken to install the pipework for an outdoor tap:

Step One

Decide on where you want to place the outside tap. It should ideally be close to the internal cold-water mains supply to reduce the amount of plumbing required to make the tap work. Usually, the outside wall adjacent to the kitchen sink is the ideal location providing the tap can be positioned above an open drain.

Step Two

Mark the outside wall with the height of the tap, ensuring that it’s high enough above ground level for a watering can or bucket to be held underneath it.

Step Three

Identify suitable positions inside the house to take the plumbing through the outside wall and to make the connection to the cold-water pipe. Ideally, this should be directly underneath the tap position on the outside wall to keep the pipe run as simple as possible.

Step Four

From the inside of the house, drill a hole right through to the outside of the house at the appropriate position using a long masonry drill. Once you have a full hole right through to the outside, open it up to 22mm using a 22mm masonry drill-bit via a hammer action drill.

Step Five

Measure the thickness of the wall and cut a piece of 22mm copper pipe to the correct length so that it can be inserted right through the wall as a protective sleeve for the actual water pipe.

Step Six

Turn off the water supply and cut into the cold-water supply pipe. It is normal for some water to come out at this point. Fit a coupling to connect the new pipe to this. Along the pipe-run to the hole through the wall, fit an inline shut off valve, a double check-valve, and a drain cock.

Step Seven

Run the pipe through the wall through the copper pipe and route it to a back-plate elbow. Secure this elbow to the wall using some wall plugs and screws after the pipework has been cut to length and the couplings have been tightened.

Step Eight

Screw your outside tap into the back-plate elbow by using some plumber’s compound on the thread.

Step Nine

Before you turn your water supply back on, be sure to check the tightness of all of the compression joints and close the drain cock, the outdoor tap, and the inline shut-off valve.

Step Ten

Turn your water supply back on and check the pipes for leaks. Open up the inline shut –off valve and check again for leaks. Open the outside tap and check the flow of water. Then, close the outside tap and check it again for leaks.

Step Eleven

Apply some mastic sealant to the gap that is between the sleeving and the pipe, and also between the masonry and the sleeving.

Step Twelve

Finally, protect your pipework from freezing by fitting it with some insulation materials.

Can I Install an Outside Tap Myself?

Installing an outside tap is a job that can be done as a DIY project, but only if the location of the outside tap is close to the main water pipe.

However, for the best job possible and to ensure that there aren’t going to be any unexpected leaks, it is always recommended to hire a professional to complete the job for you.

For taps that are located further away from the mains water pipe, some extensive plumbing may need to be completed, in which case you will need an experienced plumber to complete the job of fitting an outside tap for you.

If you were to complete the installation of an outside tap yourself, you may be able to save yourself around £150-£270 per day in labour charges. However, if you don’t complete the job correctly, you may end up with some plumbing malfunctions or leaks which could end up costing a lot more in the long run.

Therefore, we would always recommend you choose an experienced plumber to complete your outdoor tap installation.

Types of Outdoor Tap

There are a few different types of garden tap that you can choose from. While the common garden tap is the most popular option due to its availability and ability to adapt to a number of fittings, there are some other options should you wish to choose something a bit different. Below are the different types of outdoor tap to choose from.


Common Garden Tap

The common garden tap is a great all-round tap as it is adaptable to your needs through different attachments. You can easily fit a hose or pressure washer to a common garden tap, or you can simply run it as a regular tap if you would like to fill up a watering can. Common garden taps usually cost on average around £6-£10.

Old Style Vintage Tap

An old-style vintage tap doesn’t tend to have any grooves in it that allow for hose attachments, so this type of tap can usually only be used simply as a tap. This type of outdoor tap is perfect if you are looking for a more traditional garden theme.

These vintage styles of taps usually cost on average around £25-£35. They most often come in pairs so you can have a cold water tap and a hot water tap if you wish.

Lever Tap

A lever tap is similar to a common garden tap where it allows for different attachments such as a hose or pressure washer attachment. However, the top of this tap is slightly different as it features a lever rather than a turn tap.

A lever tap can be seen as being a bit more convenient as it is quicker to turn on and off. A lever tap usually costs on average around £18-£25.

Benefits of an Outside Tap

There are many benefits to having an outdoor tap. Below is a list of some of the main benefits to having an outside tap installed.

  • You can easily wash your car using s hose or power washer attachment.
  • You can fill a paddling pool during the summer months.
  • It gives builders access to a water source outside without having to run a water line from inside the house. This is useful if you are having work done on your house or garden.
  • You can easily clean bikes, scooters, and other outdoor items that may get dirty over time.
  • You can wash down your pets after a muddy walk.
  • You can easily water your flowers and plants with a hose attachment instead of having to re-fill a watering can over and over.
  • You can clean bins and other things that may become grimy over time.
  • You can clean items that you don’t want to clean inside the house.

Where Can I Put an Outside Tap?

You may be wondering where you can fit an outside tap. Well, you have a number of different options depending on the design of your home and what you want to use your tap for.

An outdoor tap can be fitted to any wall on the outside of your house. It is much easier to fit an outside tap on a wall that has direct access to the main water pipe, such as the kitchen sink wall.

If you wanted to install your garden tap on a different wall of the house, this would involve some very extensive plumbing work which could increase the cost of the job by £1000+ depending on the extent of plumbing work needed.

The closer you can get the tap to the water mains pipe, the better water pressure you’re going to get from the tap.

You can also have a tap installed anywhere within your garden as a standalone feature. This, however, would involve some plumbing work in order to allow the water to flow to the tap correctly.

To avoid freezing in the winter, the water pipes running to your standalone tap would need to be installed below ground level.

Alternatives to an Outdoor Tap

If having an outdoor tap installed at your home isn’t an option, or if you would prefer to go down an alternative route, there are some other options that may work for you. Below are some of the most popular alternatives to an outdoor tap.

Water Butt

A water butt is a large container that collects natural rainwater. This can be collected from the guttering around the house or can simply be left open to collect rainwater itself.

Once the water has collected in the butt, it can be used for things such as watering plants or filling up a bucket.


Many water butts will come with an on/off tap attached near the bottom of it so that you can easily fill up buckets and watering cans from it.

The average cost for a water butt is usually somewhere between £30-£200 depending on the size of water butt that you’re looking for.

If you have an open water butt, you can simply lay a sheet over it when it becomes full to prevent overflowing.

Watering Can

A watering can is a cheap, simple and easy solution for when you just have a few plants to water in the garden.

It can easily be filled up from the kitchen sink and, provided you don’t have an extra-large garden or a particularly huge amount of plants to water, it should only take a few trips to the kitchen sink to fill up the watering can and get the job done.


A watering can isn’t a huge expense. They usually cost on average around £5-£15. Prices can vary depending on the size of the watering can and the material that the watering can is made from. Plastic watering cans are usually the most budget-friendly option.

Hiring an Outside Tap Installer Checklist

There are a number of things that you should consider before hiring someone to come out and fit an outside tap for you. Below is a checklist of things that you should consider before hiring a plumber to carry out this work for you.

  • How much experience does the plumber have with fitting outdoor taps?
  • Is more than one plumber required to carry out the work?
  • What options does the plumber offer in terms of style and placement of the tap?
  • Be sure to ask for a breakdown of costs so that you know exactly what you’re paying for.
  • Get at least three quotes to ensure that you’re getting a good price for the work needed.
  • Does the plumber offer any guarantees with their work?
  • Does the plumber offer to fix or replace any parts that may become faulty?
  • Will the plumber remove any materials or waste as necessary?


What is a double check valve on an outside tap?
A double check valve incorporates two spring loaded non-return valves. This device prevents a back flow of water from re-entering the mains system as per the water regulations.
How do I attach a hose to an outside tap?
Outside taps usually come with a screw end. This allows you to screw a hose attachment directly onto it. You then simply attach the hose end to this screwed on attachment to fully connect the hose to your tap.
Does my garden tap have to be fitted to a wall?
You don’t necessarily need to have your garden tap fitted to a wall. Although it is much easier and will provide much better water pressure if you have your tap installed on the outside of the kitchen sink wall, you can have your tap installed as a standalone feature.

You will need some extensive plumbing work to ensure the flow of water reaches the tap correctly, but it is definitely possible to have an outside tap installed away from a wall if required.
How much does an outdoor tap cost?

The cost for an outdoor tap alone is usually somewhere between £6-£10.

What factors can affect the cost of having my outdoor tap installed?
There are a few factors that could affect the cost of your outdoor tap installation. The main factors that can affect the cost of this job are the location of the tap, the location of your property within the UK, and whether or not extensive plumbing work is needed to complete the job.
