Why Boiler Repairs Matters

When your boiler breaks down, it's more than just an inconvenience - it's a safety concern and a threat to your home comfort. A faulty boiler can leave you without heating or hot water, particularly problematic during cold Kent winters. Beyond the immediate discomfort, a broken boiler can waste energy, increase your bills, and in some cases pose carbon monoxide risks. That's why prompt, professional boiler repairs from Gas Safe registered engineers matter. At Greenhithe Boilers, we understand that boiler breakdowns never happen at convenient times. Our same-day emergency repair service means you won't be left in the cold for long. With over 20 years of experience repairing all major boiler brands across Kent, we diagnose faults quickly and fix them right the first time. Every repair comes with a 12-month guarantee on parts, giving you complete peace of mind. Whether it's a minor fault or a major breakdown, our expert engineers have the knowledge, tools, and genuine parts to get your heating system working safely and efficiently again.

Our Repairs Process

1

**Initial Contact & Diagnosis** - When you book your repair, we'll ask about your boiler symptoms to help our engineer prepare. We offer same-day emergency appointments for urgent breakdowns and will send you a confirmation with your engineer's details.

2

**On My Way Notification** - No more waiting around wondering when we'll arrive. You'll receive a text message when your engineer is on the way, plus an Uber-style tracking link so you can see exactly when to expect us.

3

**Thorough Fault Diagnosis** - Our Gas Safe registered engineer will examine your boiler, test all components, and identify the root cause of the problem. We use professional diagnostic equipment to ensure nothing is missed. This initial visit (up to 1 hour) costs £120.

4

**Transparent Quote** - Before any repair work begins, we'll explain exactly what's wrong, what needs fixing, and provide a clear quote for parts and labour. No hidden costs, no surprises - you're in control of the decision.

5

**Expert Repair Work** - Once you approve the quote, we'll carry out the repair using genuine manufacturer parts where possible. Our engineers work efficiently and keep disruption to your home to a minimum.

6

**Testing & Safety Checks** - After completing the repair, we thoroughly test your boiler to ensure it's working safely and efficiently. We'll check gas pressures, flue integrity, and all safety devices.

7

**12-Month Parts Guarantee** - We stand behind our work with a comprehensive 12-month guarantee on all parts fitted. You'll receive documentation of the work completed and our guarantee certificate.

Common Repairs Issues We Fix

No Hot Water or Heating

One of the most common boiler problems, often caused by issues with the diverter valve, motorised valves, or pump failure. This can also stem from low water pressure, thermostat faults, or frozen condensate pipes in winter. Our engineers quickly identify whether it's a simple fix like resetting the system or a component replacement needed.

Low Boiler Pressure

If your boiler pressure gauge is reading below 1 bar, your heating system won't work efficiently or may not fire up at all. This is usually caused by small leaks in the system, recently bled radiators, or a faulty pressure relief valve. We'll locate the source of pressure loss and restore your system to the correct operating pressure (typically 1-1.5 bar).

Strange Noises - Banging, Whistling, or Gurgling

Kettling (a loud banging noise) often indicates limescale buildup on the heat exchanger, common in hard water areas like Kent. Whistling can point to trapped air or a failing pump, while gurgling usually means air in the system or low water pressure. These noises aren't just annoying - they signal inefficiency and potential damage if left unaddressed.

Boiler Keeps Switching Off

If your boiler fires up then cuts out repeatedly, it's often due to low water pressure, a faulty thermostat, closed valves, or a blocked pump. Modern boilers have built-in safety features that shut down the system when problems are detected. Our engineers will diagnose why your boiler is short cycling and restore normal operation.

Leaking or Dripping Boiler

Water leaking from your boiler is never normal and should be addressed promptly. Common causes include corroded pipes, a faulty pressure relief valve, or degraded internal seals. The location of the leak helps us diagnose the cause - dripping from the pressure valve often means system pressure is too high, while leaks from pipe connections may indicate corrosion or loose fittings.

Error Codes or Fault Lights

Modern boilers display error codes when something goes wrong. Common codes indicate ignition failure, flue blockages, or sensor faults. While some homeowners try to reset the boiler, recurring error codes mean there's an underlying problem. We're experienced with all major boiler brands and can quickly interpret fault codes to identify the exact issue.

Boiler Repairs Pricing

We believe in transparent, honest pricing with no hidden costs. Our diagnostic visit charge of £120 (up to 1 hour) covers our engineer's time to identify the problem with your boiler. Once we've diagnosed the fault, we'll provide a clear quote for the repair work based on the parts required and labour time needed. You'll know exactly what you're paying before any work begins, and you're under no obligation to proceed if you'd prefer to get alternative quotes. All prices include VAT, and our 12-month parts guarantee is included as standard.

Frequently Asked Questions

How quickly can you attend a boiler breakdown?

We offer same-day emergency appointments for urgent boiler repairs, subject to availability. When you call us, we'll do our best to get an engineer to you as quickly as possible. For non-emergency repairs, we typically have appointments available within 24-48 hours. You'll receive a text when your engineer is on the way, plus a tracking link so you know exactly when to expect us.

Do you charge a call-out fee?

Our initial diagnostic visit costs £120 for up to 1 hour of an engineer's time. This covers travelling to your property, diagnosing the fault, and providing you with a quote for the repair work. If you decide to proceed with the repair, this diagnostic fee is included in the overall cost.

What if my boiler is beyond repair?

If we find that your boiler is uneconomical to repair - perhaps due to the age of the unit, obsolete parts, or the extent of the damage - we'll be honest with you. We'll explain your options, which may include a replacement boiler. We can provide a free, no-obligation quote for a new boiler installation and help you understand which modern, energy-efficient models would suit your home and budget.

Are your engineers Gas Safe registered?

Absolutely. All our engineers are fully Gas Safe registered (registration number 515374), which is a legal requirement for anyone working on gas appliances in the UK. We can provide evidence of our Gas Safe registration, and our engineers carry their Gas Safe ID cards at all times. Any work we carry out complies with current gas safety regulations.

Do you repair all boiler brands?

Yes, we have experience repairing all major boiler brands including Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, Potterton, Viessmann, and many others. Our engineers undergo regular training and have access to technical support, diagnostic tools, and genuine parts for all common makes and models.

What's covered by your 12-month parts guarantee?

Our 12-month parts guarantee covers any parts we supply and fit during your boiler repair. If a part we've installed fails within 12 months due to a manufacturing defect, we'll replace it free of charge. This guarantee gives you peace of mind that the repair work will last. Labour to fit the replacement part is also covered during the guarantee period.

What payment methods do you accept?

We accept payment by all major debit and credit cards, as well as bank transfer. Payment is due upon completion of the work. For larger jobs, we can discuss payment options. We'll always provide you with a detailed invoice for your records.
