Fitting an outside tap in Glasgow typically costs between £150 and £350 and takes a plumber a few hours to half a day, connecting into your existing internal cold water supply and running a new pipe out through an external wall. In our experience, the job itself is usually straightforward, but getting the frost protection and isolation right matters more in Glasgow’s climate than in milder parts of the country, since a badly protected outside tap is one of the more common causes of a winter pipe burst.
How an Outside Tap Is Installed
- The plumber identifies the nearest suitable internal cold water pipe to connect from
- A hole is drilled through the external wall at the chosen tap location
- New pipework is run from the internal connection point through the wall
- The outside tap and a wall bracket are fitted and secured
- An isolation valve is fitted inside the property so the supply can be shut off
- The system is tested for leaks and correct water flow
Where Can an Outside Tap Be Fitted?
Most outside taps are fitted near the kitchen, since that’s usually where the nearest suitable internal pipework runs. If your preferred location is further from the kitchen, such as at the back of the garden or near a garage, the job takes a bit longer and costs more, since it means running a longer length of pipe, sometimes underground. Our Kitchen Plumbing guide covers more on how internal supply pipework is typically laid out if you’re curious about the wider system.
Frost Protection: Why It Matters in Glasgow
Glasgow gets regular sub-zero spells over winter, and an outside tap without proper frost protection is genuinely vulnerable to freezing and splitting. A good installation includes a stop valve fitted inside the property, positioned so you can drain the external section of pipe before a hard freeze. Some installations also use a frost-proof tap design that automatically drains itself once the water’s turned off, reducing the risk further. Our What Glasgow Homeowners Should Check Before Winter guide covers this and other seasonal checks worth doing every year.
Do You Need an Isolation Valve?
Yes, and any properly fitted outside tap should include one. An isolation valve lets you shut off water to the external tap specifically, without affecting the rest of the house, which matters for two reasons: it lets you drain the outside section before winter, and it means a future leak or repair on the outside tap doesn’t require turning off water to the whole property.

Common Problems With Outside Taps
- Freezing and splitting pipework over winter if not properly isolated and drained
- Dripping or leaking from a worn washer inside the tap itself
- Reduced flow if the isolation valve hasn’t been fully opened after winter
- Corrosion on older, unprotected outdoor pipework
Glasgow-Specific Considerations
We fit outside taps across Glasgow city centre, East Kilbride, Paisley, Hamilton, Motherwell, and Rutherglen. Tenement flats and properties without a private garden may have more limited options for where a tap can be fitted, and shared drainage or external walls sometimes need factor or landlord permission before work starts, which is worth checking ahead of booking.
Why Choose a Gas Safe Certified Engineer?
Fitting an outside tap isn’t gas work, so it doesn’t itself require a Gas Safe registered engineer. That said, choosing a plumbing company where the team is Gas Safe registered for their broader work is still a good sign of a properly run business overall the same standards around insurance, accountability, and quality tend to carry across every job they do, not just the gas-related ones.
Frequently Asked Questions
How much does it cost to have an outside tap fitted in Glasgow?
Typically £150 to £250 for a standard installation near the kitchen, rising to £250 to £400 if the pipe run is longer or more complex.
How long does outside tap installation take?
Most installations take a few hours to half a day, depending on the pipe run length and wall thickness.
Do I need to winterise my outside tap every year?
Yes, it’s worth isolating and draining the outside section before the first hard frost each winter, especially in Glasgow’s climate, to prevent the pipe freezing and splitting.
Can an outside tap be fitted anywhere on the house?
In principle yes, but locations further from existing internal pipework cost more due to the longer pipe run required. The kitchen wall is usually the simplest and cheapest option.
What should I do if my outside tap has frozen?
Don’t apply direct heat to a frozen pipe. Turn off the isolation valve if you can access it, and let it thaw naturally, or call a plumber if you suspect the pipe has already split.
Do tenement flats need permission to fit an outside tap?
Often yes, since it involves the building’s external wall or shared drainage. It’s worth checking with your factor or landlord before booking the work.
