About

Meet John Harvey

John Harvey — JH Plumbing, Witney

Witney's trusted plumber for over 15 years

I'm John Harvey, and I've been working as a plumber in and around Witney since 2009. In that time I've worked on everything from dripping taps in Victorian terraces to full central heating installations in new builds across Oxfordshire.

When you call JH Plumbing, you get me — not a call centre, not a subcontractor. I'll come out, take a look, give you a straight answer on what needs doing and what it'll cost, and then I'll get it sorted.

I'm Gas Safe registered and OFTEC certified, which means I can work on both gas and oil-fired systems — particularly useful for homes in rural Oxfordshire that are off the gas grid. I'm fully insured and I always leave a job as tidy as I found it.

I'm based in Hailey and cover Witney and all surrounding towns and villages. Got a problem — big or small — give me a call.

FAQ

Frequently Asked Questions

Answers to the most common questions about boilers, gas, heating and plumbing in Witney and Oxfordshire.

Boilers & Gas

Boiler & Gas Questions

Why has my boiler lost pressure?
Boiler pressure drops are usually caused by a small leak somewhere in the system, a recently bled radiator, or a faulty pressure relief valve. If your pressure gauge reads below 1 bar, the boiler may lock out and stop working. John can diagnose and fix the cause — not just top it up — so it doesn't keep happening. Call 07515 284286 for a same-day visit.
How often should a boiler be serviced?
Once a year, ideally before winter. An annual boiler service keeps it running efficiently, maintains your warranty, and catches small problems before they become expensive ones. John carries out boiler services across Witney and Oxfordshire — call to book yours in.
Do I need a Gas Safe registered engineer?
Yes — it's a legal requirement. Any work on gas appliances, boilers, or pipework in the UK must be carried out by a Gas Safe registered engineer. John is Gas Safe registered (582126). You can verify this at gassaferegister.co.uk. Never let an unregistered person work on your gas.
My boiler keeps switching itself off — what's wrong?
This is called "lockout" and can be caused by low pressure, a faulty thermostat, a blocked condensate pipe, or issues with the heat exchanger. It's the boiler protecting itself. John can run a full diagnostic and get it running again — usually same day.
How long does a boiler installation take?
A straightforward like-for-like boiler replacement typically takes one day. A full new installation with new pipework may take two days. John will give you a clear timeframe and fixed price before any work starts.
What is LPG and do you work on LPG systems?
LPG (Liquefied Petroleum Gas) is used in many rural Oxfordshire homes that aren't connected to the mains gas network. It's stored in a tank in the garden and works similarly to mains gas. John is LPG Safe certified and can install, service, and repair LPG boilers and heating systems across West Oxfordshire.
What is an oil boiler and do I need an OFTEC engineer?
Oil boilers burn heating oil rather than gas — common in rural areas like Burford, Charlbury, and Chipping Norton that are off the gas grid. OFTEC registration is the oil equivalent of Gas Safe. John is OFTEC registered (C101762) and can service, repair, and install oil-fired boilers throughout Oxfordshire.

Central Heating

Central Heating Questions

What is a power flush and do I need one?
A power flush forces water and cleaning chemicals through your central heating system at high pressure to remove sludge, rust, and debris that builds up over time. Signs you need one: cold spots on radiators, discoloured water when bleeding radiators, noisy boiler, or slow heating. It typically takes half a day and can significantly improve efficiency and extend system life.
Why are my radiators cold at the top but warm at the bottom?
This is a classic sign of trapped air in the radiator. It needs bleeding — a simple job that takes minutes. If the problem keeps recurring, it may indicate a bigger issue with the system. John can bleed your radiators and check the cause during any visit.
Why are some rooms cold while others are warm?
Uneven heating is usually caused by an unbalanced system, failing pump, blocked pipework, or sludge build-up. A power flush often resolves this. John will diagnose the cause and advise the best solution.
My heating comes on but some radiators don't get warm — why?
The most likely cause is a stuck or faulty thermostatic radiator valve (TRV), sludge in the radiator, or a balancing issue. John can identify which radiators are affected and fix them efficiently.

Plumbing

General Plumbing Questions

How much does a callout cost?
John charges a callout fee plus an hourly rate for most jobs, or a fixed price for larger work. He'll always give you a clear price before starting. Free no-obligation quotes are available for bigger jobs. Call 07515 284286 to discuss.
Do you cover emergency callouts?
John offers same-day callouts during working hours (Monday to Friday, 9am–5pm) and will do his best to get to urgent jobs as quickly as possible. For the fastest response always call directly on 07515 284286.
What areas do you cover?
John is based in Hailey and covers Witney and all surrounding towns and villages including Carterton, Burford, Eynsham, Woodstock, Charlbury, Chipping Norton, Bampton, and Faringdon. Not sure if you're covered? Just call.
I'm a landlord — do you do gas safety certificates?
Yes. John carries out annual gas safety inspections and issues CP12 certificates for landlords and letting agents across Witney and Oxfordshire. This is a legal requirement for all rented properties. Call to book or to discuss ongoing arrangements for multiple properties.
Can you do small jobs like a dripping tap?
Absolutely — small jobs are always welcome. A dripping tap or running toilet wastes more water than you'd think and often signals a worn washer or valve that's simple to fix. And while John's there, he'll happily cast an eye over anything else you're not sure about.
