Customers often mention fast installations, tidy engineers, and a clear online booking process. Many reviews point to competitive pricing and straightforward value. A smaller group describes missed appointments, slow fault fixes, and one electrical compliance concern. These negatives appear often enough to suggest uneven scheduling and post-sale follow-up.
Examples from available reviews (Sep 2025 – Mar 2026).
Fast next-day installation; saved £950 compared to local contractor.
“the whole install was £950 cheaper than a local contractor”
Service appointment missed despite payment; customer now awaiting refund.
“waited in for them not to show up did not even get a phone call”
Company failed to disclose electrical work not done to Worcester standard.

Flawless service overall; engineer Alex resolved additional system issues.
“The service was flawless from Start to finish.”
Many reviews describe quick installs by professional, tidy engineers. Several customers mention careful workmanship and polite behaviour on site. A clear minority report no-shows and a lack of return visits for faults, which differs from the main feedback.
Numerous reviewers say the cost is lower than local contractors, with clear pricing and no hidden fees. Many also treat the fast turnaround in busy periods as part of the value. Comments about poor value are rare and link to missed appointments rather than price.
Many customers describe an easy online journey for quotes and bookings, with appointments arranged quickly. Multiple reviews mention a usable website and straightforward choices. Fewer, but repeated, comments mention cancellations and limited follow-up.
Customers often praise the installation quality and how the new boilers run after fitting. Installers repeatedly get credit for neat work and leaving homes clean. A small number of reviews mention a fault after installation that needed extra visits.
Several reviews mention helpful call-centre staff and having one reachable project lead during installation. Engineers are often described as explaining the work clearly while on site. A few reviews highlight weak communication around missed visits and an electrical installation standard issue.
Most reviews describe a good experience from quote through commissioning and aftercare. The main negatives focus on scheduling problems and slow fault resolution. The overall picture mixes fast, professional installs with occasional breakdowns in service.
For each review, the core experience based on original source reviews.
