A broken boiler is more than an inconvenience—it's a crisis. Without heating or hot water, your home becomes uncomfortable and potentially unsafe for children and elderly residents. In winter, a failed boiler can lead to frozen pipes, causing additional damage worth thousands of pounds.
Manako Plumbing specialises in rapid boiler repair. We service all major brands (Baxi, Ideal, Worcester, Vaillant, Viessmann, and more) and get your heating back on within hours, not days. We've repaired thousands of boilers across Berkshire and Slough and know how to diagnose and fix problems quickly.
Common Boiler Problems We Fix
- No hot water or heating: Complete loss of heating or hot water supply, often due to thermostat failure, ignition problem, or gas supply issue
- Boiler won't ignite or keeps shutting off: Faulty ignition, low pressure, or safety lockouts preventing operation
- Leaking boiler or pipework: Water pooling around the boiler or dripping from pipes, requiring urgent attention
- Loss of pressure: Boiler pressure gauge dropping, causing heating system to fail
- Strange noises or vibrations: Kettling, banging, or grinding sounds indicating scale buildup or component failure
- Error codes and fault lights: Boiler display showing fault codes that prevent operation
- Thermostat not responding: Room temperature control not working, boiler won't turn off or on

Frequently Asked Questions
How much does boiler repair cost?
Costs vary significantly by fault type and boiler model. Simple pressure top-ups start from £180. Component replacements range £200-£600. We always provide a fixed written quote before any work begins.
What's your response time for boiler repairs?
Same-day response for most repairs (1-2 hours in Slough, up to 4 hours in outer Berkshire). Weekend and evening appointments available for emergency situations.
Do you repair all boiler brands?
Yes. We service and repair Worcester, Baxi, Ideal, Vaillant, Viessmann, Glow-worm, Potterton, and all other major UK and European boiler brands. Older discontinued models are also covered.
Do you guarantee your work?
Yes. All repairs are covered by a 12-month parts and labour warranty. If the same fault reoccurs within 12 months due to a defect in our work, we'll fix it at no cost.
Is it worth repairing or should I replace the boiler?
This depends on boiler age and fault type. If your boiler is over 15 years old or has had multiple repairs, replacement is often more cost-effective. We'll advise honestly at the quote stage. Generally: repair if under £500 and boiler less than 10 years old; consider replacement if over £700 and over 12 years old.
Can you repair my boiler if it's not Gas Safe registered?
We can repair any boiler as long as the installation was done safely. If there's a safety issue, we'll advise. All our repairs are Gas Safe certified and safe.
Do you provide a service certificate?
Yes. All repairs include a service certificate for your records and insurance purposes. This confirms the work has been done safely by a Gas Safe engineer.
What causes boiler pressure loss?
Common causes: small leaks in pipes or radiators, open bleeding point, faulty pressure relief valve, or a heating system leak. Our engineer will identify the source and fix it. Topping up pressure without fixing the leak won't solve the problem.
