Introduction
A garden tap seems simple. Turn it on, water comes out. Turn it off, it stops.
But when it leaks, freezes, or refuses to stop dripping, you quickly realise there is more to it than meets the eye. Getting it fitted correctly from the start saves you from all of that.
At Catalyst Home Services, we send a qualified fitting plumber to homes across London for garden tap work every day. Whether you need a brand-new tap installed, an old one replaced, or a persistent drip sorted, we handle it properly.
This guide covers everything you need to know — types of garden taps, how installation works, what can go wrong, and when to call a professional.
What Is a Garden Tap and Why Does It Need a Professional Fitting Plumber?
A garden tap connects directly to your home’s cold water supply. That connection goes through an internal stopcock, a run of copper or plastic pipe, and an exterior fitting on your outside wall.
It sounds straightforward. The problem is that every property is different. The pipe run, wall material, water pressure, and location of your stopcock all affect how the job is done. A poorly fitted tap can cause:
- Water leaks behind the wall
- Frozen and burst pipes in winter
- Low water pressure throughout the house
- Damp and structural damage over time
A fitting plumber who knows what they are doing will assess your property, use the right materials, and leave you with a tap that works reliably for years.
Types of Garden Taps
Standard Bib Tap
The most common type in UK homes. It mounts directly onto the outside wall via a brass backplate. Straightforward to fit, easy to maintain. If your home already has one and it just needs replacing, this is usually the quickest and most affordable option.
Self-Draining Garden Tap
Designed for the UK climate. When you turn this tap off, any water sitting in the exterior pipe drains away rather than freezing overnight. If your current tap regularly freezes in winter, switching to a self-draining model is a sensible fix. Our fitting plumber team can advise on the right choice for your property.
Ball Valve Tap
A quarter-turn design that opens and closes the water flow completely, with no rubber washers to wear out. Longer service life than a standard bib tap but slightly more expensive upfront.
Two-Way Garden Tap
Has two outlets on the same fitting — useful if you want to run a hose and a watering system at the same time without constantly swapping connections.
How Garden Tap Installation Works
Here is what happens when a fitting plumber visits your property for a new garden tap installation.
Step 1: Site Assessment
The plumber checks where your stopcock is, inspects the route for the pipe run, and identifies the best point on the exterior wall for the tap. The aim is the shortest, most direct pipe route with the fewest bends.
Step 2: Isolate the Water Supply
Before any work starts, the water is turned off at the relevant stopcock. If you are not sure where yours is, this is also a good opportunity to locate it — useful knowledge for any future plumbing emergency.
Step 3: Pipe Run and Drilling
The plumber drills through the external wall — usually 22mm — and runs the pipe from the connection point inside to the exterior tap fitting. Copper pipe is the traditional choice for reliability; plastic push-fit pipe is often used for easier installation in tight spaces.
Step 4: Fitting the Tap
The tap body is secured to an external wall plate. All connections are made with proper fittings and PTFE tape or compression joints, then tested for leaks before the plumber leaves.
Step 5: Isolating Valve
A good fitting plumber will always install a dedicated isolating valve on the internal pipe run. This lets you turn off just the garden tap in winter or for repairs, without interrupting water to the rest of the house.

Common Garden Tap Problems and How to Fix Them
Dripping Tap
The most common complaint. In a standard bib tap, this is almost always a worn rubber washer. Cost-effective to fix — a fitting plumber can replace the washer and have water running properly again within an hour.
Tap That Won’t Stop Running
Usually a failed washer or a damaged valve seat. Sometimes the tap itself is beyond economic repair and replacement makes more sense. We can advise honestly on which applies.
Frozen Garden Tap
If your tap or the exterior pipe freezes in cold weather, do not force it or pour boiling water on it. Slow thawing with warm (not hot) water is safer. The long-term solution is either a self-draining tap or insulating the pipe run with foam lagging.
Leaking from the Base or Wall Plate
This often means the back connection has worked loose or the PTFE seal has failed. Left too long, water can track back into the wall cavity. Call a fitting plumber early — it is a small job that becomes a bigger one if ignored.
Low Water Pressure at the Tap
If pressure is fine inside the house but weak at the garden tap, the issue is usually a partially blocked isolating valve or a kink in the pipe run. If pressure is low throughout the property, that is a separate issue — see our water pressure services for more information.
Garden Tap Maintenance: What You Should Do Each Year
You do not need to do much to keep a garden tap working well. But a few simple checks each year make a real difference.
Before winter: Turn off the isolating valve inside. Drain any water from the external pipe. If you have a standard tap (not self-draining), disconnect any hoses — water trapped in a connected hose will freeze and back up into the fitting.
In spring: Turn the tap back on slowly and check for drips at the fitting, the wall plate, and the pipe connections inside. Catching a small leak early is always cheaper than dealing with a big one.
General: Avoid overtightening the tap when turning it off. It damages the washer faster than normal use does.
If you are on an annual maintenance contract with us, your plumbing checks — including outdoor fittings — are covered as part of routine visits.
When to Call a Fitting Plumber vs. DIY
Some homeowners do fit their own garden taps. The job is legal to do yourself in the UK as long as you follow water regulations — specifically, you must notify your water supplier if you are making a new connection to the mains supply.
That said, there are situations where calling a fitting plumber is the right move:
- You are not confident drilling through masonry
- You cannot locate or access your stopcock
- Your existing tap is connected with old lead pipe
- There is signs of damp around the current tap position
- You want the work done to a guaranteed standard
Our team carries all the parts needed for standard garden tap installations and can usually complete the job the same day you call.

FAQs
How much does it cost to fit a garden tap in London?
A standard garden tap installation typically costs between £80 and £180 depending on the complexity of the pipe run and wall type. We provide a fixed quote before starting. Book a fitting plumber to get an accurate price for your property.
Do I need permission to install a garden tap?
No planning permission is needed. However, under UK water regulations, you should notify your water supplier when making a new connection. We handle that notification as part of the service.
Can a garden tap be fitted to a flat or maisonette?
Yes, though access to the stopcock and pipe routing can be more complex in flats. Call us to discuss your property before booking.
How long does installation take?
A straightforward installation takes 1 to 2 hours. Properties with difficult access or older pipe systems may take longer.
My tap keeps dripping — is it worth repairing or replacing?
For a standard bib tap, a washer replacement is inexpensive and worth doing. If the tap body is corroded or cracked, replacement usually makes more sense. Our plumber will give you an honest assessment on the day.
