How Much Does a Boiler Repair Cost in London? A Homeowner’s Guide

If your boiler has stopped working or is showing signs of trouble, your first question is likely: “How much will this cost to fix?” Boiler repair prices can vary depending on the issue, boiler type, and your location—but we’ve broken it down to give you a clear idea of what to expect in London.

Average Boiler Repair Costs in London

Here’s what most homeowners in London pay for common boiler issues:

Minor repair (sensor replacement, pressure adjustment): £90–£150

Mid-level repair (pump, valve, or diverter replacement): £150–£300

Major repair (PCB board, fan, or heat exchanger): £300–£500

Emergency call-outs (evening/weekend): Add £50–£100

At Boiler Repair Experts London, we always provide clear, upfront pricing—no hidden charges.

What Factors Affect the Cost?

Not every repair costs the same. Here are the main factors that affect your final bill:

Boiler make and model: Premium brands like Worcester Bosch or Vaillant may have more expensive parts

Age of your boiler: Older boilers may need harder-to-find parts or extra labor

Type of fault: Simple sensor issues cost less than replacing a faulty heat exchanger

Time of day: Evening, weekend, or emergency services may cost slightly more

Access and setup: Boilers in tight cupboards or flats with limited access can add labor time

We always inspect and quote before beginning work so you know exactly what to expect.

When Is It Better to Replace Than Repair?

If your boiler is over 12 years old, out of warranty, and the repair will cost more than £400, it might be worth considering a replacement. A new, energy-efficient boiler could lower your bills and come with up to 10 years warranty.

We’ll always advise you honestly if a repair isn’t cost-effective—and offer a free quote for installation if needed.

How to Avoid Surprise Costs

To avoid unexpected boiler problems and high repair bills, consider:

Annual servicing to keep your system in good condition

Magnetic filters to prevent sludge build-up

Boiler cover plans that include parts and labor

Regular bleeding of radiators and pressure checks

Prevention is always cheaper than an emergency repair.
