New Heating System Installation in Oxfordshire

Do you have an old Floor standing boiler?

Do you have undersized pipework?

Full Central Heating System Upgrades Across Oxfordshire

Plumbbob Limited design and install complete new central heating systems across Oxford, Abingdon, Cumnor, Kidlington, Cowley, Headington, Didcot and the surrounding Oxfordshire villages. If your heating relies on old floor-standing boilers, undersized microbore pipework or inefficient 1960s back boilers and radiators, a full system upgrade can dramatically cut running costs and transform day-to-day comfort.

Our Gas Safe engineers handle the whole job — boiler replacement, pipework upgrades, new radiators, controls and commissioning — as one tidy package with a single fixed written quotation.

Do you have an inefficient Back boiler and radiators stuck in the 60’s?

If your home still runs an old back boiler behind a gas fire with narrow 8mm or 10mm microbore pipework, you are almost certainly losing heat and paying more in gas bills than you should. Microbore pipework is prone to blockages, kinks and poor flow — we routinely recommend upgrading to modern 15mm and 22mm copper to restore proper circulation and efficiency across the whole system.

A full system upgrade — boiler, pipework, radiators and controls — varies significantly based on property size, number of radiators, brand selected and whether existing infrastructure can be reused. We always start with a free home survey and issue a fixed written quotation before any work begins. Call 01865 717734 to arrange.

A complete heating system upgrade in an average 3-bed home typically takes 3 to 5 working days. Larger properties or conversions (e.g. gravity-fed to combi) can take a little longer. Your written quotation will specify the expected timeline.

Not always, but if you are experiencing cold radiators, blockages, kinks or restricted flow, upgrading microbore (8mm/10mm) to 15mm or 22mm copper will dramatically improve efficiency and comfort. We’ll assess during the survey and only recommend it if it will make a real difference.

Yes — as Worcester Bosch accredited installers we can register extended manufacturer warranties of up to 12 years on selected models. Other brands typically carry 5–10 year warranties, all registered on your behalf.

Yes, briefly — the heating and hot water will be off while we disconnect the old system and install the new one. We aim to restore hot water on the evening of day one where possible, and always schedule full system installations to minimise the disruption to your household.
