What boilers in Nantwich actually look like right now

Nantwich Georgian and half-timbered properties carry 12–18 year Vaillant, Worcester and Potterton system boilers with vented cylinders; some newer conversions have 5–10 year premium combis.

Nantwich boiler-repair work is defined by scale and access. Vaillant Turbomax pump seizures, Worcester Greenstar diverter scaling, Potterton PRV damage from scaled seats — we descale rather than replace where we can and quote honestly on access-driven labour.

Nantwich water hardness & magnetic filter advice

Local hardness: Hard (typically 220–300 mg/L CaCO₃) — Cheshire aquifer.

Nantwich water is hard (200+ mg/L). Every combi repair here should carry a scale reducer quote; every system-boiler repair should include a scale check.

Why you shouldn't be sold a new boiler in Nantwich without a proper diagnosis

Nantwich customers get quoted premium "heritage" rates for standard Gas-Safe repairs. There is no premium for period-property boilers — access is a labour-time question, not a heritage surcharge.

Our promise on every Nantwich boiler-repair call-out: a free visit to attend and diagnose, a fair fixed quote in writing before any billable repair starts, and the visit non-refundable — it covers the engineer's home visit.

Recent Nantwich customer reviews

"Listed timber-framed townhouse. Previous plumbers had said it was 'impossible' to fit a modern boiler. KJ specced a rear elevation flue with conservation, routed pipework through the pantry — beautiful clean install."

Vanessa L., Welsh Row · Boiler swap in listed building, Welsh Row

"Underfloor manifold on our new build had been leaking slowly for months. Isolated, replaced the failed actuator, re-balanced the loops. Written report I could send to the developer."

Peter M., Stapeley · UFH manifold repair, Stapeley

"Rural oil boiler stopped firing in December. Diagnosed a stuck solenoid, cleaned, replaced the nozzle, back on within the hour. Fair honest quote and no upsell."
