Sherborne St John Central Heating Engineers
Magnetic-filter & power-flush specialists — local team covering RG24 and surrounding areas.
Central heating upgrades in Sherborne St John cover the full spectrum: radiator replacements, smart thermostat retrofits (Hive, Nest, Tado), unvented cylinder swaps, zoning the upstairs and downstairs separately, and full boiler+cylinder+rads replacement. Realistic timelines, written quotes — full system jobs typically run 3-5 days on site with heating restored every evening.
Why this matters in Sherborne St John
Sherborne St John customers most often ask about full-system replacements when the existing boiler is 12+ years old and the rads are running uneven — at that point a coordinated boiler+rads+cylinder job is usually cheaper than five years of patch repairs. Basingstoke and Deane Borough Council planning permissions are only needed for unusual flue or condenser positions; we handle the paperwork either way.
Covering Basingstoke and Chineham too.

Central Heating in Sherborne St John — common questions
What does a full central heating install cost in Sherborne St John?+
For a typical 3-bed period cottages: combi+8 rads+controls roughly £6,500-£8,500; system boiler + 210L unvented cylinder + 10 rads runs £8,500-£11,000. Larger Sherborne St John homes with system redesign 5-8 days on site, £11k+. We quote precisely after survey, not "from £X" headline numbers.
Does my Sherborne St John system actually need a power flush?+
Only when the diagnosis says so. We check the magnetic filter, run a thermal imaging sweep across the rads, and test inhibitor levels before recommending. Many Sherborne St John systems just need a filter retrofit and a chemical clean — a third of the cost of a full flush. Common pattern in period cottages.
How much does central heating cost in Sherborne St John?+
For context: filter retrofit + power flush typically £450-£650, partial repipe with rad upgrades £1,200-£2,500, full boiler+cylinder+rads replacement £6,500-£9,500. We give a precise written quote after the survey — not a "from £X" headline figure.
Will moving to a system boiler need a new cylinder in Sherborne St John?+
Almost always. The old G3-unsafe vented cylinder gets replaced with a modern unvented one (typically 180-210L), the loft tanks come out, and the airing cupboard is reclaimed. Worth doing properly rather than reusing an outdated cylinder.
