Boiler Replacement
Expert Boiler Replacement from Gas Wizard Heating
How It Works
A Gas Safe engineer inspects your property, checks pipework and radiators, and measures heat loss to size the correct boiler for your house type — terrace, semi or detached.
Why Choose us for Boiler Replacement?
Local, family‑run engineers
A trusted local team led by Robert Wilson — friendly, respectful engineers who understand Northumberland homes and deliver reliable workmanship.
Gas Safe & Baxi Approved
All work is carried out by Gas Safe-registered engineers and as a Baxi Approved Installer we fit manufacturer-backed boilers with recognised warranties.
Transparent aftercare
Clear quotations, commissioning paperwork and scheduled reminders — plus structured service plans to protect your new boiler and keep it efficient.
Survey-led replacements that fit your home. We begin with a full heat‑loss assessment to ensure the replacement boiler is correctly sized — undersized units struggle to heat older terraces in Blyth, while oversized units waste fuel. That assessment also identifies whether a combi, system or heat‑only boiler best suits your existing cylinders and radiators.
Installation with minimal disruption. Our engineers protect floors and furniture, schedule sensible access times and complete pipework neat and tidy. We handle removal and environmentally responsible disposal of your old boiler, fit the flue to current Building Regs, fully commission the new unit and leave you with user-friendly controls. If you want smart thermostats or zone controls we can advise on compatibility and installation.
