About

Run by Nigel. Backed by fifteen years of word of mouth.

PHBLUE started in 2010 with a single van and one rule: leave the house tidier than we found it. Fifteen years later, that's still the rule. Most of our work comes from word of mouth: neighbours telling neighbours, landlords telling other landlords, and the occasional builder calling in a favour.

Who actually does the work

I'm Nigel Phillips, founder, lead engineer, and the person who'll usually be on your doorstep. I've been a Gas Safe registered engineer since 2010. I have a small, hand-picked team of plumbers and electricians I trust, all Welsh-trained, Welsh-based, and held to the same standard as everything I do myself.

Fifteen years, briefly.

The shape of how PHBLUE grew: small steps, kept on doing the same things, never the cheapest, never the loudest.

    PHBLUE founded

    One van, one rule: leave the house tidier than we found it. Gas Safe registered from day one.

    Part P registered for domestic electrical installations. Every install notified to the local authority.

    Verified Google reviews

    Hundreds of jobs completed across Cardiff and South Wales. Word of mouth still our biggest source of work, a metric we're unusually proud of.

Who turns up at your door.

A small team, named, accredited, and accountable. The same engineers on the next job, not a rotating cast of contractors.

Used PHBLUE for our 6-flat block annual cycle: CP12, EICR and smoke alarms all in single visits per flat. Certificates land within two days every time. Compliance reporting is a single CSV. No chasing required. Switched from a cheaper firm last year and won't go back.

How we work

The promises we actually keep.

We answer the phone. We turn up when we say we will. We give you a fixed quote for most jobs and an honest written estimate for the bigger ones. We don't charge call-out fees on jobs we go on to quote. We tidy up before we leave. We tell you if you don't actually need a new boiler. And we won't sell you a heat pump unless it's right for your house.

We work with a single triage line out of hours so genuine emergencies get prioritised, and dripping taps don't wake anyone up at 2am.
