Before & After
A tired High Wycombe bathroom,rebuilt from the pipework up
Drag the handle across the photo to see the same room before and after. This was a full bathroom installation: the old bath came out, the waste and feed pipework was re-run and pressure tested, and the room was re-tiled floor to ceiling before the new suite went back in.
- Old bath, panel and dated tiling stripped out, with the pipework re-run and tested before anything new went in
- New bath fitted with a black-framed shower screen, wall-hung basin unit and concealed-cistern WC to free up floor space
- Full-height porcelain tiling and dark floor tiles supplied and laid by our own tiler, inside the original quote
- Left clean, sealed and working, with a one-year workmanship guarantee on the installation

Local Heating Specialists
Boiler and heating engineerswho know Wycombe housing stock
High Wycombe homes are a real mixture: Victorian terraces off the Desborough Road, post-war semis in Downley and Sands, and newer estates out towards Cressex and Hazlemere. Each one throws up its own heating problems: old microbore pipework that sludges up, radiators that never warm at the bottom, combi boilers pushed well past what they were sized for, and pressure that drops week after week without an obvious cause.
That is where a heating specialist earns their money. Rather than swapping parts and hoping, we find the actual fault first: whether that is a failed diverter valve, a system full of magnetite that needs power flushing, or a hidden leak quietly pulling your pressure down. You get told what is wrong, what it will cost to put right, and what will happen if it is left. Then you decide.
On boiler replacements the same principle applies. The system gets sized to the house rather than to whatever is quickest to fit, the install is done by a Gas Safe registered engineer, and the new unit is registered so you get the full manufacturer warranty, up to twelve years depending on the boiler and the manufacturer's own terms. We are also currently working toward Vaillant Approved Installer status.
And when something goes properly wrong: no heat in January, hot water gone before work, a leak coming through a ceiling, the 24-hour line is answered first time. No queue, no message service, no waiting until Monday morning.
Common Questions
Everything homeownersask us before booking
Do you really answer the phone at 3am?+
Yes. Emergency cover is genuinely 24 hours and the phone is answered first time; you speak to the engineer, not a call centre taking a message for the morning. Any type of emergency is covered: no heat, no hot water, leaks and burst pipes included.
Are you Gas Safe registered?+
Yes. JY Plumbing & Heating Ltd is Gas Safe registered under registration number 975777. You are welcome to check that number on the Gas Safe Register before we start, and we carry £2 million public liability insurance.
How much does a call-out cost?+
Quotes are always free. Most jobs are priced on a fixed quote, so the figure you agree is the figure you pay. Where the job can't be fixed-quoted up front, a £100 call-out fee applies and is explained to you before we attend.
Is your work guaranteed?+
All work is backed by our 1-year workmanship guarantee. New boiler installations also carry up to a 12-year warranty, with the exact length depending on the boiler and the manufacturer's terms.
Do I need to find my own tiler for a bathroom?+
No. We cover the full bathroom job. Tiling is carried out by a trusted tiler we work with regularly, and it is included in the original quoted price, there is no separate tiler to arrange or pay.
How can I pay?+
Credit card, debit card and cash are all accepted. On larger jobs such as installations and bathrooms, a deposit is taken before work begins.
Still unsure? Ring 07833 203288 and ask; no charge for a straight answer.
