What We Fix

Most boiler repairs fall into a handful of root causes. We deal with all of them:

• No heating or hot water (lockouts, failed ignition, sensor faults, circulation issues)
• Boiler losing pressure (small leaks, PRV discharge, expansion vessel, filling loop issues)
• Fault codes and repeated lockouts (we diagnose the cause, not just reset it)
• Strange noises (banging, gurgling, kettling, whistling) see: boiler noises guide
• Leaking boilers (minor drips to active leaks that need isolating quickly)
• Radiators not heating (cold spots, balancing issues, air, sludge)
• Hot water temperature problems (combi DHW faults, diverter valves, flow sensors)

If it is repairable, we will fix it. If it is uneconomical or unsafe, we will tell you straight and talk through the options. No wasted money on pointless parts.

How It Works

1. You call or book online. Tell us what the boiler is doing and any fault code showing.
2. We schedule a slot. For urgent no heating or hot water, we prioritise same day or next day where possible.
3. An engineer arrives. Gas Safe registered, ID carried, and experienced with London housing stock.
4. Diagnosis first. We test safely, identify the cause, and explain it in plain English.
5. Fixed price agreed. You get a clear price before repairs begin.
6. Repair and safety checks. Most faults are repaired in one visit with common parts stocked in the van.

No surprises. If a job takes longer than expected, the agreed price does not change.

Before You Call (60-Second Checks)

These quick checks fix a surprising number of lockouts. Do not do anything you are not comfortable with.

1. Check boiler pressure (if you have a pressure gauge). If it is below 1.0 bar, you may need to repressurise. Full guide: boiler pressure guide.
2. Check the fuse box (a tripped circuit can look like a boiler failure).
3. Check thermostat and programmer (power cuts and clock changes can reset settings).
4. If it is freezing outside, the condensate pipe may be frozen. See: frozen condensate pipe guide.
5. Reset once only. If it locks out again, stop and call an engineer.

All Boiler Brands

We repair and service all major boiler brands commonly found in London homes:

Older boilers too. If parts exist, we can usually source them. If parts are becoming scarce, we will be honest about whether a repair still makes sense. See: repair or replace guide.

How We Price Repairs

Boiler faults vary, so we do not guess over the phone. Our approach is simple:

• Diagnosis first: confirm the fault safely and correctly.
• Explain the cause: what failed, why it happened, and what needs to be done.
• Fixed price agreed: you approve the price before repairs start.

If the boiler is beyond economical repair, we will say so and point you towards the best next step, including new boiler installation when appropriate.

Beyond Repairs

A repair is not always the right answer. We also provide:

• Boiler servicing to keep your boiler safe, efficient, and reliable
• Gas Safety Certificates (CP12) for landlords
• Power flushing when sludge is restricting circulation
• New boiler installation when replacement is the sensible choice

Frequently Asked Questions

Do you cover my area?

Yes. We cover all London boroughs. If you are in London, we can usually help. Use online booking or call 0203 695 3137.

Is no heating or hot water an emergency?

If a vulnerable person is in the property (baby, elderly, medical needs), treat it as urgent. If you have hot water but no heating, it is often safe to wait until the next available slot.

Will you repair or try to upsell a new boiler?

We repair when it is sensible. If a boiler is failing repeatedly or needs a major component on an older unit, we will explain the economics and let you decide. No pressure.

Can you help with pressure dropping?

Yes. Pressure loss is usually a leak, expansion vessel fault, or PRV discharge. See our guide: boiler pressure keeps dropping.

What if the condensate pipe is frozen?

This is common in cold snaps and can cause lockouts. Use this guide: how to fix a frozen condensate pipe. If it keeps happening, we can reroute or insulate it properly.
