Service Overview

Boiler Repair & Breakdown:
The Brief, In Plain English.

What It Is

Diagnosis and repair of any domestic boiler, gas, LPG or oil. Lockouts, pressure issues, no-heat, no hot water, error codes, PCB failures, pump and valve replacements.

Who It's For

Homeowners and landlords across Leicestershire with broken or unreliable boilers, all makes, all ages.

When You Need It

The moment the boiler locks out, the radiators stay cold, or you've topped up the pressure more than once in a week.

Why It Matters

An unrepaired fault gets worse and more expensive. Diagnose properly first time, fit the right part, and the boiler keeps running for years longer.

What Happens If You Wait

The Cost Of
Doing Nothing.

Boilers don't fail fairly, they fail in February. Get it diagnosed properly, first time.

Risks Of Ignoring It

  • Repeated lockouts ruining heat exchangers, turning a £150 repair into a £1500 replacement.
  • Wrong parts fitted by under-qualified engineers, voiding warranty.
  • Carbon monoxide risk from faulty seals or flues left in service.
  • Cold homes during winter for vulnerable family members.

Common Mistakes Customers Make

  • ×Topping the pressure up repeatedly without finding the leak.
  • ×Hitting reset over and over, the fault is still there.
  • ×Ignoring error codes hoping they go away.

Ask Yours

How much is a diagnostic call-out?

+

Fixed price quoted on the phone before the engineer arrives, covering attendance, diagnosis and a written quotation for any repair.

Do you carry parts?

+

Yes, every van carries common spares for major makes including PCBs, pumps, fans, diverter valves and sensors. Most repairs complete first visit.

When should I replace instead of repair?

+

Honest rule: if repair exceeds half the cost of a new boiler and yours is 10+ years old, replacement usually saves money long-term.

How quickly can you attend a boiler breakdown?

+

Same-day attendance on most calls, with emergencies prioritised within 60–90 minutes across Leicestershire.

Will my repair affect my warranty?

+

No, we use manufacturer-approved parts and log every repair properly, keeping your existing warranty intact.

What does a typical boiler repair cost?

+

Most common repairs fall between £150 and £450 fitted, including parts. The quote is given before any work starts.

Can you repair boilers other plumbers won't touch?

+

Yes, older Worcester, Vaillant, Vokera, Potterton, Glow-worm and discontinued models still serviceable with sourced parts.

What if the part isn't available?

+

We honestly advise replacement when parts are obsolete and offer a transparent comparison of repair vs replacement costs.
