System flushing before a new boiler installation is not optional in Gloucestershire — it's a manufacturer warranty requirement. In Mitton homes with older heating systems, we powerflush the entire circuit to remove sludge, rust, and debris that would otherwise damage the new boiler's heat exchanger within months.
Every boiler we install in Mitton comes with a Gas Safe certificate, manufacturer warranty registration, benchmark commissioning checklist, and building regulations notification. These documents protect you legally and financially — and we ensure they're all completed and handed over as part of the installation.
A riverside area on the edge of Tewkesbury, Mitton's character homes along the Avon present rewarding bathroom renovation opportunities.
Mitton sits at the confluence of the Severn and Avon, with period properties and a rural character despite its proximity to Tewkesbury.
Mitton's riverside location means ground-floor bathrooms should use flood-resilient materials and have accessible plumbing for post-flood recovery.
water is moderately hard in most of Gloucestershire (150-250 mg/l calcium carbonate). Limescale builds up on shower heads, taps, and heating elements — thermostatic valves and easy-clean coated shower glass help manage this. many older Gloucestershire homes have solid stone or brick walls (no cavity), which means fixing bathroom fittings requires different techniques — heavy-duty masonry anchors and careful drilling to avoid cracking stone.
Boiler flue positioning regulations affect where the boiler can be installed in Mitton homes. The flue must be a minimum distance from windows, doors, and air bricks. We survey flue options during the initial visit — because discovering a flue problem mid-installation causes costly delays.
System flushing is essential when fitting a new boiler in Gloucestershire. Old heating systems in Mitton properties contain sludge, rust, and debris that can damage a new boiler's heat exchanger. We powerflush the system and fit a magnetic filter to protect your investment — most manufacturer warranties require this.
If your Mitton home has an old-style programmer timer, upgrade to a smart thermostat when you get a new boiler. The combined savings from a new boiler plus smart controls are greater than either alone.

The boiler installation process in Mitton follows a clear sequence. First, we visit and survey. Then we provide a written quote with a full breakdown. Once accepted, we agree dates and order materials. On day one, we protect your home, set up our workspace, and begin the strip-out. From there, each day follows a planned schedule until handover.
Quality boiler installation in Gloucestershire takes time — and we don't rush. Mitton homeowners sometimes receive quotes from other contractors with unrealistically short timescales. If someone promises to complete in half the time we estimate, ask yourself what corners they're cutting. Proper preparation and careful execution need adequate time.
Not insulating hot water pipes in unheated spaces. Exposed pipes in your Mitton loft, garage, or underfloor space waste heat and freeze in winter. Insulating them costs very little and saves significant energy.
Blocking radiators with furniture. Placing a sofa directly against a radiator in your Mitton home reduces its output by up to 30%. Leave at least 150mm clearance for proper heat circulation.
Assuming all radiators should be the same size. Each room in your Mitton home has different heat loss characteristics based on window size, insulation, and exposure. BTU calculations should be done room by room.
