07809 414913Why Avanza
A Premium Installer
You Can Actually Get Hold Of.
Most Essex installers either chase volume or hide behind a showroom. Avanza is owner-led by Pierre Codarin — direct contact, fixed written quotes, properly finished work.
One Team, Every Trade
Bathrooms, heating and plumbing handled in-house — no subcontractor merry-go-round, one accountable team start to finish.
Same-Day Response
Call us before midday and we're with you the same day. Emergency boiler, leak or no-heat call-outs prioritised 24/7.
Finishes Built To Last
Gas Safe installs, properly tanked wet-rooms, designer-grade finishes. The unglamorous bits done right so the showroom finish actually lasts.

Answers.
Got something specific? Call 07809 414913 — Pierre answers the phone himself.
Are you Gas Safe registered and insured?+
Yes — Avanza Heating & Bathrooms is Gas Safe registered for all gas appliance work, fully insured, and a registered limited company (Company No. 17201187). Gas Safe is our only listed accreditation. Evidence available on request.
How fast can you get to me?+
We're open 24/7. Call by 12pm and an engineer will be with you by 4pm the same day. Emergency call-outs (no heat, no hot water, leaks, bursts) are handled round the clock.
Which areas do you cover?+
Southend-on-Sea, Chelmsford, Basildon, Colchester, Brentwood, Rayleigh, Wickford, Billericay, Harlow and the wider Essex region. If you're not sure, phone us and we'll confirm in seconds.
Do you handle the whole bathroom renovation, or just the install?+
Both. We can take a luxury bathroom from initial design through strip-out, plumbing, electrics, tiling and final fit — or step in for a specific stage if your project already has a designer in place.
Are quotes and surveys free?+
Yes — quotes and on-site surveys are completely free with no obligation. Once issued, your written quote price is fixed for 14 days so you can decide in your own time without anything moving on you.
Do you offer a workmanship guarantee?+
Yes — every install comes with a 1-year workmanship guarantee on top of any manufacturer warranties on parts, boilers and sanitaryware. All paperwork handed over at sign-off.
