The biggest decision in boiler replacement for Selsley homeowners is whether to switch from a conventional (tank) system to a combi boiler. Combis save space and provide instant hot water, but they can struggle in homes with multiple bathrooms running simultaneously. We assess your usage patterns and recommend accordingly.
We install boilers across Gloucestershire with full Gas Safe certification and manufacturer-backed warranties. In Selsley, our most popular installations are combi boiler replacements — typically completed in one day with minimal disruption. We also handle system and regular boiler installations for larger properties.
Sitting on the edge of Selsley Common above Stroud, Selsley's stone-built homes and steep lanes need bathroom installers used to working in characterful Cotswold properties.
Selsley is dominated by Cotswold stone cottages, Victorian villas built for nearby mill workers, and a few modern infill houses on the slope down towards the canal.
Selsley's hillside position can mean low mains pressure on upper floors — pumped showers and unvented cylinders are often the right answer.
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 Selsley 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 Selsley 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 Selsley 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.
Register your new boiler's warranty online within 30 days of installation. Gloucestershire homeowners in Selsley sometimes forget this step and discover they have no manufacturer warranty when they need it.
When your Selsley boiler is replaced, ask for the old boiler's benchmark commissioning record — this tells the new installer how the system was set up originally, which helps with the new installation setup.

The boiler installation process in Selsley 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. Selsley 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 Selsley 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 Selsley 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 Selsley home has different heat loss characteristics based on window size, insulation, and exposure. BTU calculations should be done room by room.
