How it works

From enquiry to a finished installation

No pressure-sell survey, no vague estimate. This is exactly what happens on every Thermotec installation.

Step 01
Free home survey
Online enquiry or call direct. Stuart visits to assess the property, existing system and what's needed.
Step 02
Fixed-price quote
A written, fixed-price quote follows the survey — no obligation to proceed, no pressure on the day.
Step 03
Installation
Most boiler swaps are a one-day job. Larger system installs are scoped and scheduled clearly in advance.
Step 04
Full system test
Gas tightness check, system flush and balance, every radiator and control tested before handover.
Step 05
Warranty registration
Manufacturer warranty registered on completion — up to 12 years on Vaillant and Viessmann installations.
Step 06
Annual service reminder
Annual servicing keeps your warranty valid and your system running efficiently — reminders sent when due.

Things to consider

What to think about before installing

A few practical points Stuart covers during every survey, so there are no surprises after the quote.

Boiler sizing
An undersized or oversized boiler wastes money for years. A proper heat-loss calculation gets it right first time.
Unvented vs vented
Unvented cylinders give stronger flow but need a G3 qualified installer by law — always check before committing.
System cleanliness
Installing a new boiler onto an old, sludged system risks early failure. A powerflush is often recommended alongside installation.
Warranty registration
Extended manufacturer warranties require registration within 30 days and annual servicing — Thermotec handles registration on your behalf.
Underfloor heating compatibility
Most boilers can run underfloor heating alongside radiators, but the system needs correct zoning and blending valves.
Smart control compatibility
Not every smart thermostat works with every boiler — Stuart confirms compatibility before recommending a brand.
