Common Red Flags in Boiler Quotes

Watch out for:

Unusually low prices – often means poor-quality parts or inexperienced installers.
No itemised breakdown – vague pricing can hide unexpected fees.
No proof of Gas Safe registration – always check credentials.
Cash-only offers – lack of professionalism and accountability.

Choosing a legitimate, transparent provider like MPH Trades ensures your installation is safe, compliant, and cost-effective.

Boiler Prices and Installation in Cardiff: What Impacts the Cost?
