No jargon. No runaround. A Gas Safe registered engineer who turns up when they say they will, tells you clearly what's wrong, and leaves a proper record behind.
What we do
Residential plumbing and Gas Safe heating across Hemel Hempstead and London. Every job logged. Every record yours to keep.
From a dripping tap to a full bathroom install — we cover everything water related in your home.
Gas Safe registered. Boilers, radiators, heating systems — serviced, repaired, and maintained properly.
Compliance, continuity, and a proper paper trail. Everything a landlord or letting agent needs — in one place.
The WHP Standard
Most trades companies start from zero each time they visit. We don't. Every job we do is logged, every record is yours — and we hold ourselves to a standard you can actually feel.
Your home is not a job site. We arrive when we say, communicate when we can't, and leave every space better than we found it.
We do what's right, not what's easy. No upselling work you don't need. No cutting corners on work you do.
Nothing is hidden. Every job is recorded — what was found, what was done, what was used. It's already there, waiting for you.
We explain what we found, what we did, and why. You're never made to feel like you shouldn't ask.
Every job ends with a complete record, ready for whoever comes next. You should never pay twice for the same ignorance.
Where we work
We keep our coverage focused so we can keep our service excellent. No stretched thin — just properly resourced, genuinely local.
Our home base. Local reputation, word of mouth, and strong community presence anchored here first. If you're in Hemel or the surrounding Hertfordshire area — we're your local engineer.
A strong domestic market with high landlord and rental density. Ideal for our landlord and lettings service. We cover Ealing, Harrow, Wembley, and surrounding west and northwest London.
Why WHP
Other trades companies are not bad. They just don't operate to a written standard. We do.
No four-hour windows. No no-shows without a call. Your time is as valuable as ours.
We explain what we found and what we did — clearly, before we do anything and after we're done.
Every job is logged against your property. Next engineer, wherever they're from, starts informed — not from zero.
We recommend what's needed. If it can wait, we'll say so. If it can't, we'll tell you why — clearly, honestly.
Landlords get certificates, service records, and renewal reminders. Nothing slips through the cracks.
Fully qualified, registered, and insured. You can verify our credentials — and you should.
Pricing
No hidden extras. No surprise invoices. We'll always tell you what something will cost before we do it — and explain why.
Some jobs have a set price. You'll know the exact cost before we arrive — no surprises, no extras.
Diagnostic and repair work is charged by the hour. We'll always agree an estimate with you before we start — and tell you if it changes.
Bigger jobs get a free, itemised quote. Written down, clearly explained. No pressure — you decide when you're ready.
Not sure which applies to your job? Just ask — we'll tell you upfront.

Word of mouth is our first channel. Every review earns the next job.
"Turned up exactly when he said. Explained the problem clearly before doing anything. Job done quickly and cleanly. Best tradesperson I've used in years."
"Finally a plumber who sends a proper job report afterwards. I've had three engineers visit in the last two years and none of them left me with any record. WHP were different."
"Manage four properties in Ealing. Having someone reliable for the gas safety records who actually communicates is a relief. Will be using WHP for all four going forward."
