In most homes, replacing a flexible water supply hose (a flexi pipe) typically costs between £60 and £120, with higher totals if additional valves or fittings are required. Replacing a gas flexi connector usually falls in the £80 to £170 range, and requires a Gas Safe engineer. Costs vary by region, length of the hose, accessibility, and whether multiple components must be replaced.
Flexible pipes come in water and gas varieties and are used to connect taps, dishwashers, washing machines, boilers, and other appliances. Replacement costs depend on the type of pipe, its length, the fittings needed, and the labor required to access the pipe, shut off supplies, and complete the job safely. In some cases, you may also need to replace shut-off valves, which can add to both parts and labor costs.
What counts as a flexi pipe and when replacement is needed
Flexible hoses and connectors can wear, crack, or corrode over time, leading to leaks or bursts. Common scenarios include a leaking tap connector, a corroded gas flex connector to a boiler or cooker, or an upgrade to braided stainless-steel hoses for improved durability. Because gas work requires safety oversight, replacements involving gas lines should only be performed by a licensed professional.
Typical cost ranges by type
Costs differ depending on whether you’re dealing with a domestic water supply hose or a gas connector. The following ranges reflect common domestic replacement scenarios.
- Water supply flexi hoses (tap connectors, under-sink lines): £60-£120 for a simple swap; £100-£180 if a new valve or extra fittings are needed.
- Gas flexi connectors (to boilers, stoves, or water heaters) — installation must be carried out by a Gas Safe engineer: £80-£170 total (parts typically £5-£25; labour £60-£150).
- Other flexible hose replacements (appliance-specific hoses or external connections): £50-£150 depending on length, accessibility, and complexity.
Concluding: For water hoses, expect a straightforward replacement at the lower end of the range, with higher totals if valves or adaptors must be swapped. For gas connectors, the price includes professional safety checks and compliance, which drives the overall cost higher.
Regional and situational factors
Prices can vary by region. Urban areas, especially London, may command higher call-out fees and labor rates, while rural areas can be cheaper but may involve travel time. Accessibility matters a lot: a hose behind a dishwasher or inside a cramped cabinet may require more time. If multiple components must be replaced at once, the total bill may rise, but some plumbers offer bundled or fixed-price deals for combined tasks.
In gas-related work, regulatory compliance and safety checks add to the cost. Many plumbers provide a written quote that itemizes parts, labor, and any required safety certificates, which helps avoid surprises at the bill stage.
Tips to manage costs
Before you hire, consider these strategies to keep costs in check. The following list explains common approaches to cost management.
- Obtain at least three quotes from licensed tradespeople and compare both parts and labor charges.
- Ask whether the price includes all necessary fittings and a safety check, especially for gas work.
- Ask about fixed-price or bundled quotes if you have multiple flexi hoses or related components to replace.
- Check the age and condition of related valves; sometimes replacing a valve with the hose saves a future leak.
- Plan for potential access issues (tight spaces, cabinetry) that could add time to the job.
Concluding: Being proactive—clearly describing the replacement needs, requesting quotes that itemize parts and labor, and choosing a qualified professional—helps ensure you get a fair price without compromising safety.
Summary
Replacing a flexi pipe can range from roughly £60 to £180 for water hoses and £80 to £170 for gas connectors, with regional variations and job complexity driving the final figure. Simple, accessible replacements tend to be on the lower end, while gas work and tasks requiring valve changes or extensive access push costs higher. Always use a licensed professional for gas-related replacements, and obtain multiple quotes to compare parts, labor, and any needed safety checks. Planning ahead and understanding what the job entails can help you budget accurately and avoid costly surprises.
