Having an outside tap fitted is one of those relatively small home improvements that can make life considerably easier. Whether you’re watering the garden, filling a paddling pool, washing the car or connecting a pressure washer, it saves repeatedly running buckets through the house.
So, how much does it cost to fit an outside tap in the UK in 2026?
For a straightforward installation, a sensible budget is around £120–£200 including materials and labour, with approximately £160 being a useful average according to Checkatrade’s June 2026 pricing data.
Other current UK pricing sources put simple installations slightly lower, around £80–£150, so homeowners can certainly receive quotes below £120 where the plumbing is particularly straightforward.
The biggest factor is usually not the tap itself. It is how easily the plumber can connect the new tap to your existing cold-water supply.
If there is suitable pipework immediately inside the wall — for example, beneath the kitchen sink — the installation can be relatively simple. If new pipework has to travel several metres through the house or garden, the cost can rise substantially.
This guide explains typical outside tap installation costs in 2026, what affects the price, what should be included and when paying extra for frost protection or hot water might make sense.
If you’re replacing an existing indoor tap instead, see our guide to how much it costs to replace a tap in the UK.
Average outside tap installation cost in 2026
Here is a useful starting point for budgeting:
| Outside tap job | Typical cost |
|---|---|
| Standard outside tap installation | £120–£200 |
| Typical average | Around £160 |
| Very straightforward installation | Around £80–£150 |
| Longer internal pipe run | Around £150–£250 |
| More complex connection to rising main | Around £150–£300 |
| Hot-water outside tap | Potentially £150–£300+ extra |
| Tap positioned further into garden | £300+ depending on pipework |
These are ballpark UK figures rather than fixed prices. Checkatrade currently gives £120–£200 as its typical materials-and-labour range, while MyJobQuote puts a straightforward installation at approximately £80–£150.
The actual quote depends heavily on your property.
What does a standard outside tap installation include?
The simplest installation usually involves placing the outside tap on the opposite side of a wall from an accessible cold-water supply.
A typical installation might involve:
- isolating the water;
- connecting into an appropriate cold-water pipe;
- drilling through the external wall;
- running the necessary pipework;
- installing appropriate isolation and backflow protection;
- mounting the outside tap;
- reconnecting the water;
- checking the installation for leaks.
Where everything is easily accessible, this can be a relatively small plumbing job.
But move the tap away from that convenient water source and the amount of work changes quickly.
Why does fitting an outside tap cost £120–£200?
The physical tap itself can be inexpensive.
Most of the price comes from the professional’s time, fittings and installation.
Your quote may need to cover:
- plumber’s labour;
- travel/call-out;
- outside tap;
- pipe;
- connectors;
- valves;
- wall plate;
- backflow protection;
- drilling through the wall;
- testing.
MyJobQuote estimates that a basic outside tap itself may cost only around £6–£10, with basic kits around £20–£30.
That illustrates why buying a £10 tap does not mean the entire job should cost £30.
You are primarily paying to connect it properly to the property’s water system.
What affects the cost of fitting an outside tap?
Distance from the water supply
This is probably the biggest factor.
The ideal situation is something like this:
Kitchen sink → external wall → new outside tap.
The plumber has an accessible cold-water supply immediately behind the proposed tap.
Now imagine you want the tap on the opposite side of the house.
Additional pipework may need to run through:
- kitchen units;
- utility rooms;
- cupboards;
- walls;
- floors;
- external areas.
That requires more labour and materials.
Checkatrade specifically identifies the location of the water source and amount of work required as major factors affecting installation cost.
Type of external wall
Drilling through an ordinary accessible brick wall can be straightforward.
Installation can become more complicated where the property has:
- unusually thick walls;
- stone construction;
- difficult external finishes;
- inaccessible cavities;
- awkward internal cabinetry.
A plumber may therefore need to inspect the proposed position before giving you an accurate fixed price.
Where you want the tap
Installing a tap directly outside the kitchen is very different from supplying one at the bottom of the garden.
MyJobQuote’s 2026 pricing data illustrates the difference particularly well: a basic tap on the kitchen wall is estimated at £80–£150, while a surface-run supply to the bottom of a garden is around £300–£400. A buried supply can become considerably more expensive because excavation and frost protection are involved.
So when asking:
“How much is an outside tap?”
the location is essential information.
Your location in the UK
Labour prices vary geographically.
You may pay more in:
- London;
- the South East;
- other higher-cost areas.
Prices can be lower elsewhere.
Travel, parking and local demand can also influence what a plumber needs to charge for a relatively small job.
This is why national averages should be used for budgeting, not as a guaranteed quotation.
Standard vs frost-resistant tap
A basic outdoor tap may be perfectly adequate, but frost protection deserves consideration because exposed water pipes can freeze during cold weather.
Some frost-resistant systems cost more than a basic installation.
Another approach is to have an accessible internal isolation valve so the outside supply can be shut off when required.
The correct arrangement depends on how the pipework is installed.
Does an outside tap need a double check valve?
Backflow protection is an important part of outside-tap installation.
WaterSafe advises that garden taps should have a compliant double check valve, explaining that this helps prevent contaminated water from a garden hose flowing back into the drinking-water supply.
This matters because a hose can contain stagnant or contaminated water.
The wider Water Supply (Water Fittings) Regulations exist in England and Wales to help prevent contamination, waste and misuse of public water supplies.
A professionally installed outside tap should therefore not simply be:
pipe + cheap tap + hole in wall.
Appropriate backflow protection forms an important part of the installation.
Does an outside tap need an isolation valve?
An internal isolation valve is extremely useful.
It allows the outside tap supply to be shut off without turning off the water to the entire property.
This can help when:
- replacing the tap;
- carrying out maintenance;
- dealing with a leak;
- preparing the installation for cold weather where appropriate.
Ask the plumber whether an accessible internal isolation valve is included in the quote.
How long does it take to fit an outside tap?
A straightforward installation where a suitable water supply is directly behind the proposed tap can often be completed relatively quickly.
Current trade pricing guidance suggests the simplest installations may take around an hour or two, while MyJobQuote allows approximately half a day for a basic kitchen-wall installation.
More complicated installations can take longer.
For example, the plumber may need to:
- move appliances;
- remove cabinet panels;
- run additional pipe;
- drill difficult walls;
- work around existing services;
- install pipework over a longer distance.
Do not assume that because your neighbour’s tap took an hour, yours will too.
Can you have an outside hot-water tap?
Yes.
An outside tap does not necessarily have to provide cold water only.
A hot or mixed-temperature outdoor supply can be useful for:
- washing dogs;
- cleaning equipment;
- filling children’s pools with warmer water;
- certain outdoor cleaning tasks.
However, additional plumbing makes the installation more expensive.
MyJobQuote estimates that providing hot water outdoors can add approximately £150–£300+, depending on the arrangement.
For most households, a standard cold tap is considerably simpler and cheaper.
Can you have hot and cold outside taps?
Potentially.
You could have separate hot and cold supplies or an appropriate mixer arrangement.
This can be particularly useful if you regularly wash pets outdoors.
However, consider whether you will genuinely use it.
If the upgrade adds several hundred pounds and you only wash the car once a month, a standard cold tap may offer much better value.
How much does it cost to fit an outside tap away from the house?
This is where costs can rise considerably.
Suppose you want a tap beside:
- greenhouse;
- garden room;
- outdoor kitchen;
- garage;
- allotment area;
- bottom of the garden.
The plumber now needs to get water from the house to that location.
Depending on the project, this could involve:
- external pipework;
- underground pipework;
- excavation;
- insulation/frost protection;
- additional fittings;
- making good landscaping.
MyJobQuote currently estimates approximately £300–£400 for an outside tap at the bottom of a garden using a surface-run supply. Its example for a buried supply is substantially higher at around £1,000–£1,200 because of the extra work involved.
Those figures demonstrate why it is important to describe the location when requesting a quote.
Where is the best place to install an outside tap?
The cheapest location is often close to an existing accessible cold-water supply.
For many homes, that means the outside kitchen wall.
But cost should not be your only consideration.
Think about where you actually need water.
Useful locations include:
Back garden
Ideal for watering plants and filling paddling pools.
Driveway
Convenient for washing cars.
Side passage
Can provide access to both front and rear areas using a hose.
Near a greenhouse
Useful for regular watering.
Outdoor kitchen
Can form part of a more substantial outdoor plumbing installation.
If you are redesigning the entire garden, consider the tap position alongside your other landscaping plans. Our 2026 garden landscaping price guide can help you understand the wider project costs.
Is an outside tap worth having?
For many households, yes.
An outside tap can make everyday outdoor jobs considerably easier.
Watering the garden
No more filling watering cans in the kitchen.
Washing the car
Connect a hose or pressure washer directly.
Cleaning patios
Much easier than carrying water through the house.
Filling paddling pools
Particularly useful for families during summer.
Washing muddy boots
Mud stays outside rather than travelling through the kitchen.
Washing pets
Especially useful with an appropriately designed hot/cold setup.
Considering that a straightforward installation may cost around £120–£200, it can be a relatively affordable improvement compared with many other home projects.
Can you fit an outside tap yourself?
DIY outside-tap kits are available, and a competent DIYer may consider fitting one.
However, connecting anything to the drinking-water supply needs to be done correctly.
A poor installation can result in:
- leaks;
- water damage;
- freezing;
- unsuitable pipework;
- inadequate backflow protection;
- contamination risk.
WaterSafe specifically highlights the importance of compliant backflow protection for garden taps.
If you are not confident working with water-supply pipework and the applicable requirements, hiring a plumber is the safer approach.
The labour cost is relatively modest compared with repairing water damage caused by a poor connection.
Can an outside tap freeze in winter?
Yes.
Pipework exposed to freezing temperatures can freeze.
When water freezes, it expands. This can damage pipework and fittings and may result in a leak once everything thaws.
The installation should therefore take frost risk into account.
Depending on the setup, that could involve:
- positioning pipework appropriately;
- insulation;
- internal isolation;
- draining vulnerable sections;
- frost-resistant fittings.
Do not simply wrap the visible tap in something and assume the entire installation is protected — the pipework supplying it matters too.
How can you protect an outside tap in winter?
Your plumber can advise based on the particular installation, but common considerations include:
- isolating the outside supply where appropriate;
- draining vulnerable pipework;
- insulating exposed pipes;
- using appropriate frost-protection products;
- repairing dripping taps.
A constantly dripping outside tap is not only wasteful. During freezing conditions, it can also create additional problems around the tap and surrounding surfaces.
If your tap has already developed a persistent drip, our guide to why your tap is dripping and how to fix it explains the common causes.
How much does it cost to replace an existing outside tap?
Replacing an existing outside tap can be cheaper than installing one from scratch because the water supply and wall penetration may already exist.
However, the price depends on why it is being replaced.
If the plumber simply needs to remove a failed tap and install a compatible replacement, the work can be relatively straightforward.
But additional costs may arise if:
- the pipe is damaged;
- fittings are corroded;
- the isolation valve has failed;
- the existing installation lacks appropriate protection;
- access is difficult.
For comparison with other tap replacement jobs around the home, see our UK tap replacement cost guide.
Outside tap vs outdoor water butt
If your main purpose is watering plants, a water butt can reduce the amount of mains water you use.
Rainwater collected from the roof can be useful for many garden watering tasks.
The two systems can also complement each other:
water butt for routine garden watering + outside tap when mains water is required.
For keen gardeners, having both can be more practical than relying entirely on one source.
Should you install two outside taps?
It can make sense on larger properties.
For example:
Tap 1: rear garden
Tap 2: front driveway
That prevents dragging a very long hose around the side of the house.
If you are already paying a plumber to modify pipework, ask how much additional work would be required to install the second tap.
The additional cost may be reasonable if the plumbing layout makes both positions easy to supply.
How much does an outdoor shower cost compared with a tap?
An outdoor shower is a substantially different project.
A simple outside tap usually requires one cold-water supply.
An outdoor shower may require:
- hot and cold supplies;
- mixing controls;
- drainage;
- screening;
- suitable surfaces;
- more extensive pipework.
If you simply want somewhere to rinse muddy boots, bikes or gardening equipment, an outside tap is normally the far cheaper solution.
Does fitting an outside tap damage the wall?
A hole normally needs to be made through the external wall where pipework passes outside.
A professional installation should leave the penetration appropriately finished around the pipework.
The amount of disruption depends on the wall construction and where the internal supply is located.
If kitchen units need to be accessed, some internal work may also be necessary.
Ask the plumber whether any making good is included.
Can you fit an outside tap to a flat?
Potentially, but it can be considerably more complicated.
Issues can include:
- access to an external wall;
- ownership of exterior walls;
- lease restrictions;
- communal areas;
- water supply routing;
- permission from a landlord or freeholder.
If you live in a flat, do not assume you can drill through the exterior of the building simply because the wall is beside your kitchen.
Check the relevant permissions first.
Outside tap installation and garden renovations
If you’re planning major landscaping, it is worth deciding where you need water before patios, paths and lawns are completed.
Imagine spending thousands on a new patio and then deciding six months later that you want a water supply on the opposite side of it.
Installing necessary underground services beforehand may prevent finished landscaping from having to be disturbed later.
This becomes particularly relevant when adding:
- garden rooms;
- outdoor kitchens;
- greenhouses;
- irrigation;
- washing areas.
Our garden landscaping prices guide can help you plan the outdoor work as one project rather than a series of disconnected improvements.
How to get an accurate quote for an outside tap
Give the plumber as much information as possible.
Tell them:
- where you want the tap;
- what is directly behind that wall;
- where the nearest sink or water pipe is;
- whether you want cold only or hot and cold;
- whether there is easy access beneath the sink;
- what type of wall the property has if known.
Photos can also be useful.
Send one photograph of:
the proposed outside location
and another of:
the plumbing immediately inside the wall.
The plumber may still need to inspect the property, but this gives them much more useful information than simply asking:
“How much for an outside tap?”
What should be included in your quote?
Before accepting the job, establish whether the price includes:
- labour;
- tap;
- pipework;
- fittings;
- backflow protection;
- isolation valve;
- drilling;
- travel/call-out;
- VAT where applicable;
- making good.
For a simple £150 job, you may not receive a five-page quotation.
But you should still understand what the agreed price covers.
Is £200 too much to fit an outside tap?
Not necessarily.
Checkatrade’s current 2026 range for outside tap installation extends to around £200 including materials and labour, so a £200 quotation can sit within the normal range.
Whether it represents good value depends on the job.
£200 may seem relatively high if:
- the cold pipe is directly behind the wall;
- access is excellent;
- the installation is extremely straightforward.
But £200 could be very reasonable if:
- additional pipework is required;
- access is difficult;
- the wall is challenging to drill;
- you’re in a higher-cost area;
- additional fittings are included.
Compare the complete job, not just the headline number.
Is £100 a good price for fitting an outside tap?
For a very straightforward installation, £100 is plausible.
Several current UK pricing sources put simple installations around £80–£150.
But make sure the quote includes the necessary fittings and a proper installation.
A £100 compliant installation is good value.
A £100 shortcut that needs correcting later is not.
Common outside tap installation mistakes
Choosing the location purely because it looks convenient
Consider the internal plumbing too.
Forgetting backflow protection
A garden hose can present a contamination risk, so appropriate protection matters.
No accessible isolation
Being able to shut off the outdoor supply can make maintenance much easier.
Ignoring winter conditions
Exposed water pipework needs frost consideration.
Installing the tap too low
Think about whether hoses and connectors can be attached comfortably.
Installing it where a hose becomes a trip hazard
Consider how the hose will travel through the garden.
Waiting until after landscaping
Plan underground services before expensive patios and paths are finished.
Choosing purely on the cheapest quote
Compare what each plumber is actually including.
Frequently asked questions
How much does it cost to fit an outside tap in the UK?
For a straightforward installation in 2026, budget around £120–£200 including labour and materials, with approximately £160 being a useful average. Some simple installations may be available for around £80–£150.
How long does fitting an outside tap take?
A straightforward installation with an accessible nearby cold-water supply may take only a few hours or less. More complicated pipe runs can turn it into a half-day or full-day job.
Does an outside tap need a double check valve?
Appropriate backflow protection is important. WaterSafe specifically advises that garden taps should have a compliant double check valve to prevent contaminated water flowing back into the drinking-water supply.
Can a plumber fit an outside tap?
Yes. This is a common domestic plumbing job.
Can you have hot water from an outside tap?
Yes, although running an additional hot-water supply increases the installation cost. Current estimates suggest hot-water arrangements can add roughly £150–£300+ depending on the work involved.
Can you fit an outside tap anywhere?
Potentially, but the farther the location is from suitable existing plumbing, the more complicated and expensive the installation becomes.
How much does an outside tap itself cost?
Basic taps can be inexpensive, with MyJobQuote putting simple units around £6–£10 and basic installation kits around £20–£30. The majority of the overall installation cost is usually labour and associated plumbing work.
Is an outside tap worth it?
For homeowners who regularly garden, wash cars, clean patios or use a hose, an outside tap can be a relatively inexpensive improvement that makes outdoor maintenance considerably easier.
Final thoughts: how much should you budget for an outside tap?
For most straightforward installations, £120–£200 is a sensible 2026 UK budget, with around £160 being a useful average based on current Checkatrade data.
But there is an important distinction:
Tap directly behind the kitchen sink?
Probably towards the simpler end of the scale.
Tap several metres from existing plumbing?
Expect to pay more.
Tap at the bottom of the garden?
Potentially several hundred pounds or more depending on how the supply needs to be installed.
Before accepting a quote, ask what is included and whether the installation includes appropriate isolation and backflow protection.
