Fix a shower which isn’t working correctly

⭐ Introduction

A shower that isn’t working correctly can be frustrating, especially when you rely on it daily. Problems can range from low water pressure and inconsistent temperatures to leaks or a complete failure to start. Fixing a faulty shower is a common plumbing job that helps restore comfort and safety in your home.

You might need this service if your shower is not heating up properly, the water pressure fluctuates, or if you notice leaks or drips. Sometimes, issues arise after updates to your plumbing or heating system, or simply from wear and tear over time.

Getting a professional plumber involved ensures the problem is diagnosed accurately and repaired safely, complying with UK standards and regulations.

🔧 What the job involves

When a plumber fixes your shower, they’ll:

• Inspect the unit and plumbing to identify the problem – this might involve checking the mixer valve, shower head, pump, or diverter.
• Test the water pressure and temperature controls.
• Replace worn or faulty parts such as seals, valves, cartridges, or the shower head.
• Repair or replace any leaking pipes or connections.
• Ensure the shower is safely connected to your water supply and heating system.
• If it’s an electric shower, check the wiring and components comply with electrical safety standards.
• Test the system thoroughly once repairs are complete.

Repairs range from simple fixes like replacing washers to more involved tasks such as swapping out the whole mixer or electric shower unit.

📝 Step-by-step from booking to completion

1. Initial enquiry
   Contact a Gas Safe-registered plumber (for combi-boiler or electric showers) or a qualified heating plumber. Explain the problem in detail.

2. Site survey and diagnosis
   The plumber visits to inspect your shower, water pressure, heating system compatibility, and any visible signs of damage.

3. Quotation
   You’ll receive a written quote detailing labour, parts, and any extras – with a clear timescale.

4. Scheduling the work
   Agree on a convenient date for the repair or replacement.

5. Day of the works
   The plumber arrives, carries out the repairs or replacements safely, ensures compliance with UK regulations (e.g. Part P for electrical work), and tests the shower fully.

6. Aftercare advice and paperwork
   You’ll receive advice on care and maintenance, plus any warranty details and a completion certificate if required.

💷 Main costs to expect

• Parts and materials:
  • Replacement mixer valve or cartridge: £40–£100
  • Shower hose and head: £15–£60

Simple repairs might cost around £100–£200 including parts and labour. More complex jobs like full electric shower replacements can approach £300–£500.

📊 What affects the price

• Access to the shower (tight spaces increase time and complexity).

• Condition of existing plumbing and pipework.
• Compliance and certification requirements (Part P for electrical work).
• Additional remedial work like fixing leaks or replacing water pumps.
• Location—costs may vary between regions of the UK.
• Urgency/timeline—emergency work can carry premium charges.

⏱ How long does it take?

• Simple repairs or part replacement: 1 to 2 hours.
• Replacing a mixer valve or shower cartridge: 2 to 3 hours.
• Fitting a new electric shower unit with electrical safety checks: 3 to 4 hours.
• Complex plumbing work including pipe replacement or adding water pumps: can take a full day or longer.

🏠 Can you DIY it?

Small tasks like cleaning the showerhead can be done safely at home. However, fixing plumbing issues or electric showers is generally not recommended as a DIY job because:

• Plumbing repairs require knowledge of water systems and may need compliance with Building Regulations.
• Electric showers need installation by a Part P competent person or a Gas Safe-registered electrician to ensure safety and legal compliance.

Incorrect repairs could cause leaks, water damage, or electrical hazards. It’s best to hire a professional for anything beyond basic maintenance.

💰 Typical UK price range

For fixing a shower that isn’t working correctly, homeowners in the UK typically pay between:

£100 and £400 (including VAT at 20%).

This is an estimate and depends on the complexity of repairs and parts needed. Always ask for a detailed quote before work begins.

✅ Handy tips before you start

• Check your water pressure and make a note of the issue to explain clearly to the plumber.
• Locate the main water shut-off valve in case of leaks.
• Confirm the plumber’s Gas Safe or Part P registration for your type of shower.
• Keep any documentation, receipts, and warranties safe after the repair for future reference.
• Request advice on routine maintenance and servicing of your shower to avoid future problems.
• Ask the plumber if any Building Regulations or certificate forms need to be submitted to your local authority.

By preparing in advance and hiring a qualified plumber, you can get your shower working efficiently and safely again with minimal stress.
