Thames Valley Plumbing

About Us

A family-run business built on trust

We started Thames Valley Plumbing & Heating in 2009 with one van, one engineer, and a simple promise: do the job properly, charge what you quoted, and turn up when you say you will. Fifteen years later, that promise hasn't changed.

Our story

Mark Davies spent twelve years working for British Gas before deciding he'd had enough of corporate schedules and rushed appointments. He wanted to run things the way he believed they should be run — with time to do the job right and a relationship with every customer.

He bought a second-hand van, printed some flyers, and started knocking on doors in Caversham. The first year was lean. But word spread — not because of marketing, but because when Mark said he'd be there at 9am, he was there at 9am. When he quoted £280, the invoice was £280.

Fifteen years on, we've grown to a team of six engineers covering the whole Thames Valley. We've installed over 1,200 boilers, fixed thousands of leaks, and fitted more bathrooms than we can count. But we still answer the phone ourselves, and Mark still does the odd job when someone needs the boss.

What we stand for

Three principles that guide every job we take on.

Reliability

We give you a time slot and we stick to it. If something delays us — traffic, a job overrunning — we call you. You're never left wondering where the plumber is.

Transparency

You get a written quote before we lift a tool. No vague estimates, no surprise charges. If the job turns out to be simpler than expected, you pay less — not the quoted price.

Quality

We use quality parts, not the cheapest we can find. Every installation is commissioned and tested properly. And every job comes with a 12-month workmanship guarantee.
