Plumbing & Heating
Across Oxfordshire
One Local Team.
Full Gas Safe and MCS certified plumbing and heating coverage across Oxfordshire, from Witney and Carterton through Oxford city and out to Bicester, Abingdon and the Cotswold villages. Fixed-price quotes, no call centres, real engineers.
Genuinely local to Oxfordshire.
Pinnacle is an Oxfordshire company. Our base is Carterton, our directors are locally rooted, and our engineers work every OX postcode from OX1 in the city out to OX7 in the Cotswolds. We're a genuine local trade, not a national brand claiming coverage.
Emergency response times vary with distance from our Carterton base, Witney, Oxford, Carterton and immediate villages are prioritised within working hours. Further-out Cotswold and North Oxfordshire calls get an honest ETA on the phone.
The full Oxfordshire mix: Cotswold-stone period cottages, Victorian and Edwardian city terraces, interwar suburban semis, 1960s–90s estate housing, modern new-build developments, listed rural properties and off-grid rural homes on LPG or oil.
Boiler upgrades, chemical cleans on tired heating systems, bathroom renovations, landlord CP12s across the rental market, and increasing volumes of heat pump feasibility work for owner-occupied homes eligible for the Boiler Upgrade Scheme grant.

Common Oxfordshire plumbing & heating problems.
Oxfordshire's mixed housing stock, hard water and rural infrastructure produce a recognisable set of recurring calls.
Hard-water damage countywide
Chalk and limestone geology means aggressive limescale. Scale protection and correct choice of parts extend the life of every fitting installed here.
Off-grid oil and LPG heating
Rural North Oxfordshire and Cotswold villages often run on oil or LPG. Heat pump feasibility is increasingly the honest answer to escalating fuel costs.
Old micro-bore heating
8mm micro-bore in period Oxford and Witney housing throttles modern boilers. We diagnose rather than guess.
Sludge in older systems
Decades-old radiator circuits carry heavy magnetite. Cold-at-bottom rads and kettling boilers are the classic warnings.
Winter condensate freezes
Rural properties with exposed external condensate lines lock out every cold snap. Simple lagging or a rerun stops it.
Listed and conservation constraints
Cotswold and North Oxford listed housing needs planning-aware flue and pipework routing, a local installer's default habit, not an afterthought.
