How Much Does a Plumber Charge to Change a Tap?
A plumber charges £80 to £180 to change a tap in the UK in 2026, including parts for a straightforward, like-for-like replacement where the new tap uses the same connections as the old one. According to InstantCost.co.uk's 2026 UK plumbing pricing data, most plumbers apply a one-hour minimum charge for this kind of job, since the work itself, once access is sorted, typically takes 30 to 60 minutes.
The figure that actually determines where you land in that range isn't the tap you've chosen, it's what's underneath the sink or basin. A tap swap with easy access and matching connections sits at the lower end. A job involving a seized isolation valve, mismatched pipe centres, or an awkward cut-out in a worktop can push the same "simple tap change" considerably higher, sometimes into a second hour of labour or a follow-up visit.
What's Included in the Standard Price
The £80 to £180 range typically covers removing the old tap, fitting the new one, connecting to existing water supply pipes, and testing for leaks once complete. It assumes the new tap uses broadly the same connection type and spacing as the old one, and that the plumber doesn't need to source or fit any additional parts beyond the tap itself and basic fittings like flexible tap connectors.
What Pushes the Price Higher
Seized or Faulty Isolation Valves
Isolation valves that haven't been operated in years can seize, and a plumber discovering this mid-job needs to replace the valve itself before the tap change can even proceed, adding parts and labour beyond the original quote.
Mismatched Tap Connections
Older properties sometimes have pipe centres or connection types that don't match a newly bought tap without additional fittings or minor pipework adjustment, particularly when switching from separate hot and cold taps to a single mixer tap.
Worktop or Basin Cut-Out Changes
Switching tap style, from a single-hole mixer to a three-hole bridge tap, for example, sometimes needs the worktop or basin cut-out altered, which is a different job entirely from a straightforward swap and priced accordingly.
Access Difficulty
A tap in a tight, awkward-to-reach cupboard or a basin with very limited underneath access takes longer to work on than one with generous space, and labour time reflects this directly.
Kitchen vs Bathroom Taps
Kitchen mixer taps, particularly larger or more elaborate models with pull-out sprays or boiling water functions, can take longer to fit and sometimes need additional under-sink space for a boiler unit or filter, pushing costs toward the higher end compared with a simple bathroom basin tap.
A Note on Supplying Your Own Tap vs the Plumber Supplying It
Most plumbers are happy to fit a tap you've bought yourself, and this can save money compared with the plumber sourcing and marking up the tap themselves, though be aware that a plumber may be less willing to guarantee the tap itself, as opposed to their fitting work, if it wasn't supplied by them. Always clarify this distinction before booking.
A Note on Combining a Tap Change With Other Work
If you're already having a plumber out for another job, adding a tap change to the same visit is often considerably cheaper than booking it separately, since you're only paying one call-out or one-hour minimum charge rather than two. Worth mentioning when booking any other plumbing work if a tap change has also been on your list.
When to Call a Professional
A tap change is one of the more genuinely DIY-accessible plumbing jobs when access is good and connections match, but a plumber is worth the cost if you're not confident isolating water supplies safely, if the existing valves look old or difficult, or if you're changing tap style in a way that might affect the worktop or basin cut-out.

Common Mistakes and What to Do Instead
Mistake: Assuming every tap change costs the same regardless of the job's complexity. A straightforward swap and one complicated by seized valves or mismatched connections are genuinely different jobs. Ask your plumber to check access and connections before confirming a fixed price, or agree an hourly rate with a clear understanding of what might extend it.
Mistake: Buying a tap without checking connection compatibility first. Some taps need specific pipe centres or connection types that don't match every basin or sink. Check compatibility, or ask your plumber for guidance, before purchasing.
Mistake: Not clarifying whether the quote includes parts beyond the tap itself. Flexible connectors, new isolation valves if needed, and basic fittings aren't always included in a headline price. Confirm exactly what's covered before work begins.
Mistake: Assuming the plumber will guarantee a tap you supplied yourself. Some plumbers only guarantee their own labour, not the product, if you've supplied the tap. Clarify this distinction to understand what recourse you'd have if the tap itself develops a fault.
Mistake: Not combining a tap change with other planned plumbing work. Booking a separate visit purely for a tap change when other plumbing work is already planned means paying two call-out or minimum charges instead of one. Mention a tap change when booking any other job if you can.
Mistake: Ignoring warning signs of a bigger underlying issue. A tap that's been dripping for a long time sometimes indicates worn valves or pipework issues beyond the tap itself. Ask your plumber to check the wider condition while they're already working in that area.

Staying Safe
Confirm your plumber holds public liability insurance, generally £2 million as a standard minimum for domestic work, before booking. If the job somehow reveals a gas connection nearby that also needs attention, this must be handled separately by a Gas Safe registered engineer, since a general plumber isn't automatically qualified for gas work.
Ensure the water supply is properly isolated before any tap is removed, whether you're doing this yourself or a plumber is handling it, since water still under pressure when a tap is disconnected can cause a significant, sudden leak.
Always verify a plumber's public liability insurance and, for anything touching gas pipework or appliances, their Gas Safe registration, directly rather than taking a verbal assurance at face value.
Frequently Asked Questions
Is it worth changing a tap myself instead of hiring a plumber? If access is good and the new tap matches your existing connections, many confident DIYers can manage this in 30 to 60 minutes, saving the labour portion of a plumber's charge. If you're not confident isolating water supplies safely, hiring a plumber is the sensible choice.
Why did my plumber charge more than the standard quote for a tap change? This usually means something beyond the tap itself needed attention, a seized isolation valve, mismatched connections needing extra fittings, or a worktop cut-out change. Ask your plumber to explain specifically what extended the job.
Can I supply my own tap for a plumber to fit? Yes, most plumbers are happy to fit a tap you've bought yourself, though clarify whether their guarantee covers just their labour or the tap as well, since this varies.
How long does it take a plumber to change a tap? A straightforward swap typically takes 30 to 60 minutes once the plumber has access. More complex jobs involving seized valves or connection changes can take considerably longer.
Does changing from two taps to one mixer tap cost more? Yes, generally, since this often requires additional pipework changes and sometimes a different basin or sink cut-out, beyond a simple like-for-like swap.
Should I get multiple quotes for a tap change? For a straightforward job, this is less critical than for larger plumbing work, but it's still worth checking a couple of quotes if you're unsure about pricing in your area, particularly if the job might involve complications like an old or seized valve.
