Thinking about replacing your boiler? Get straight answers about the right size, heating controls, installation work and what your quote includes — from a local Gas Safe registered installer.
CHOOSE THE RIGHT RANGE
The best boiler is the one that suits your property, hot-water demand and existing system. These are comparison guides — the final model, output and installation price are confirmed after assessment. Prices are starting prices for straightforward, eligible like-for-like installations only; a written survey-based quotation will confirm equipment, labour, VAT and any additional work.
A straightforward option for a cost-conscious replacement where the specifications suit your home.
A useful middle-ground option for customers balancing equipment features, budget and longer warranty cover.
For homeowners who prioritise the longer manufacturer warranty, subject to Baxi's conditions.
* Warranty durations are manufacturer-stated for the listed ranges and subject to the exact model and terms. Baxi requires warranty registration within 30 days, completed Benchmark commissioning records and annual servicing.

Starting-price assumptions: existing compliant boiler location and suitable gas, flue, condensate and electrical arrangements; no system conversion, relocation, major remedial work or additional building works. All subject to site assessment. No installation booking is confirmed until you accept a written quotation.
THE WORK BEHIND A QUALITY INSTALLATION
Every quotation is based on the existing installation, access, condition and manufacturer's requirements.
Review heating and hot-water demand, existing system type, location and proposed boiler output.
Assess compliant flue arrangements, gas supply suitability and condensate route.
Assess system water quality and any cleaning, filter or inhibitor work needed for the proposed installation.
Discuss appropriate controls such as room thermostats and programmer options.
Carry out relevant checks, manufacturer commissioning and Benchmark documentation.
Explain controls, servicing requirements, documentation and agreed warranty-registration arrangements.
Any repairs to existing pipework, radiators, electrical supplies, flues, building finishes or other unexpected defects are quoted according to the agreed scope; they are not automatically included in a boiler replacement.
HOW IT WORKS
Fill in the quick enquiry below and share pictures of your current boiler if possible.
We review suitability, boiler range, controls and any site-survey requirements.
You'll see the proposed equipment, included work, exclusions and agreed price.
Installation, testing, commissioning and documentation, followed by servicing guidance.
REPAIRS & DIAGNOSTICS
A faulty boiler doesn't always need replacing. We investigate problems methodically, explain the findings and discuss repair options before carrying out chargeable remedial work.
Investigating loss of heating, hot-water faults, diverter and circulation issues.
Checking expansion vessels, pressure relief discharge, filling arrangements and possible system leaks.
Manufacturer-guided fault diagnosis, combustion-related checks and investigation of recurring lockouts.
Pumps, controls, radiators, valves, filter condition and system-water quality assessments.
Some faults require further tests or replacement parts. Safety-critical work is assessed and classified as applicable. Diagnosis does not guarantee that every appliance is economical or possible to repair.

COMMON QUESTIONS
It depends on the model, output, system conversion, location, flue route, controls and the existing heating system. We provide a tailored written quotation following assessment rather than advertise a misleading fixed price.
Often yes, if they're suitable and in acceptable condition. We'll assess the system and recommend any necessary remedial work.
Not necessarily. Existing system faults and contamination need to be diagnosed and addressed separately where required.
Follow the exact model's manufacturer terms. This typically includes registration within 30 days, completed Benchmark records and a service every year. Baxi 800 also has a magnetic filter requirement.
A straightforward replacement may be quicker than a conversion or relocation. We'll explain the expected timescale once we've assessed the scope.
