New Boiler Installation in Swindon: Process and Timescales

Replacement day goes smoothly when the survey was done properly. Here is the sequence and what to insist on.

Before installation day

1. Survey: a Gas Safe engineer inspects the boiler, flue route, gas supply size, radiators and controls. Combi-to-combi swaps are straightforward; fuel or position changes add work. 2. Itemised written quote: boiler model, flue, controls, magnetic filter, power flush if recommended, labour, and removal of the old unit. Compare like-for-like. 3. Check registration: confirm the installer's Gas Safe licence for the work type. Non-registered installation is illegal.

Installation day

A straightforward combi swap takes most of one working day. System changes, cylinder removal or repositioning the boiler typically run to two days. Expect water off for a few hours and heating off overnight in some cases.

After the job

Indicative 2026 installed ranges: combi swap £2,000–£3,500; system conversions £2,500–£4,000+. Not quotes — Swindon pricing varies with boiler brand and property access.
