Service Overview

Boiler Installation:
The Brief, In Plain English.

What It Is

Full boiler installation including system design, parts, labour, flushing, certification and manufacturer warranty registration. Combi, system and regular boilers, gas, LPG or oil.

Who It's For

Homeowners replacing tired boilers, upgrading inefficient systems, or installing into new builds and extensions across Leicestershire.

When You Need It

When repair costs exceed half the price of replacement, or your boiler is 10+ years old, frequently breaking down, or running inefficiently.

Why It Matters

A bad install voids your warranty, costs you in efficiency every month, and risks Gas Safe / Building Regs non-compliance. Done right, you save money for the next 10–15 years.

What Happens If You Wait

The Cost Of
Doing Nothing.

Cheap installers cut corners you only discover years later, after the warranty has been voided.

Risks Of Ignoring It

  • Warranty void from missing magnetic filter, system flush or correct gas supply.
  • Building Regs non-compliance, affects house sale and insurance.
  • Wrong-sized boiler, runs constantly or short-cycles, wasting gas.
  • Old system contamination ruining the new boiler within years.

Common Mistakes Customers Make

  • ×Choosing on price alone, installs vary by thousands for good reason.
  • ×Skipping the system flush, pure false economy.
  • ×Letting a 'mate' do it without Gas Safe certification.
