Combi conversions and boiler relocation in Stratford-upon-Avon
We cover Stratford-upon-Avon and the CV37 postcode area from our base in Warwick. Combi conversions and relocations mean new pipe routes, flue positions and often a mains flow test, so we survey the property properly before committing to a layout or a price.
Property context
Housing across Stratford-upon-Avon varies enough that no two jobs are quite the same. Older properties often hide a mix of copper, plastic and imperial pipework, while newer homes tend to run sealed systems with unvented cylinders.
Heating in the area
Most heating work in Stratford-upon-Avon is gas, and we service, repair and install condensing combi, system and heat-only boilers from the main manufacturers. Properties off the gas grid are usually on oil, and we cover Grant, Firebird, Warmflow and Worcester oil boilers too.
Plumbing in the area
We handle day to day plumbing repairs in Stratford-upon-Avon alongside larger projects such as bathrooms, ensuites, cylinder replacements and mains water boosters.

Stratford-upon-Avon combi conversions
Reclaim the cupboard, keep the hot water
A combi conversion in Stratford-upon-Avon and the surrounding Warwickshire area usually starts with the same wish: get the cylinder out of the airing cupboard and the tanks out of the loft. Done properly it delivers exactly that, along with mains pressure hot water and one appliance instead of three.
It is not the right move for every property. Homes with several bathrooms in simultaneous use, or a weak incoming main, are better served by a system boiler and an unvented cylinder. We measure mains pressure and flow rate on the survey and tell you which route the house actually supports.
Boiler relocation is the other half of this work. Moving a boiler from a loft to a kitchen, from a bedroom cupboard to a garage, or out of the way of a kitchen refit means new gas, water, condensate and flue routes, plus making good where the old one was. We plan every run before we quote so nothing gets improvised on site.
Conversion work always includes a full system cleanse, fresh inhibitor and a magnetic filter. Old pipework that is about to feed a brand new heat exchanger needs to be clean, or the warranty and the boiler both suffer.
Common signs to look out for
- Cylinder and loft tanks taking up useful space
- Airing cupboard needed for storage or an en suite
- Hot water runs out and needs an hour to recover
- Boiler is in a loft or bedroom and you want it moved
- Kitchen refit means the boiler is in the wrong place
- Old gravity-fed system with poor upstairs pressure

The three common conversions
System to combi, conventional to combi, or the other way
System to combi: the cylinder goes, the feed and expansion arrangement goes, and a single combi takes over both heating and hot water. Suits one bathroom homes and many two bathroom homes with a strong main.
Conventional (gravity fed) to combi: the biggest change of the three. Loft tanks, cylinder and old open-vented pipework all come out, and the system becomes sealed and pressurised. It is the conversion that frees the most space.
Combi to system with an unvented cylinder: the right move when the house has outgrown a combi. Several bathrooms running at once need stored hot water at mains pressure, and we are G3 qualified for unvented work.

Boiler relocation
Moving the boiler somewhere it makes sense

- New gas run sized for the boiler output
- Flue route and terminal position checked to spec
- Condensate route, ideally internal to a waste
- Heating flow and return re-piped to the new position
- Electrical supply and controls relocated
- Old position capped off and made good

Before you commit
The mains water test that decides everything
A combi can only deliver the hot water your incoming main can supply. We measure static pressure and flow rate at the kitchen tap on the survey, because that single figure decides whether a conversion will feel like an upgrade or a downgrade.
Where flow is marginal we will tell you, and we will offer the alternatives: a system boiler with an unvented cylinder, or a mains booster and accumulator where the supply itself is the limit.

Answers
Frequently asked questions
What Stratford-upon-Avon homeowners ask about combi conversions and moving a boiler.
It depends on the incoming mains flow and how many bathrooms you run at once. We flow test the main before recommending it, and say so honestly if a system boiler and cylinder would serve you better.
Typically two to three days. Tanks come out, pipework is reconfigured, the system is cleansed and everything is tested and commissioned before we leave.
Usually yes, subject to flue routes, frost protection, gas pipe sizing and access for future servicing. The survey confirms whether the position works.
They are drained, removed and taken away, and you get the loft space back. Any redundant pipework is capped off properly rather than left hanging.
Often, yes. Combis draw more gas than the appliance they replace, so we check the supply pipe size and upgrade it where the calculation says it is needed.
Removing a conventional or system setup, the hot water cylinder and any loft tanks, and replacing it with a single combi boiler that heats water on demand. It frees up the airing cupboard and loft space and removes the tanks from the equation entirely.
It suits most one bathroom and many two bathroom homes with decent mains pressure and flow. Where several showers run at once, or the incoming main is weak, a system boiler with an unvented cylinder is usually the better answer. We measure the mains on survey before advising.
Typically two to three working days. The cylinder and tanks come out, pipework is reworked, the combi is installed and commissioned, and the system is cleansed and rebalanced.
Yes. Boiler relocation is routine work for us: loft to kitchen, kitchen to utility, airing cupboard to garage. It needs new gas, water, condensate and flue routes, all of which we plan on the survey rather than improvising on the day.
To free up a kitchen cupboard, get it out of a bedroom or loft, reduce noise, make servicing easier, or open up space in a kitchen refit. Where the flue terminal is causing a problem with a neighbour or a window, relocation often solves that too.
They come out and go with us, along with the redundant pipework. Loft tanks are removed rather than left in place, and we make good where they were.
A combi runs at mains pressure, so in most homes the shower actually improves. The limit is flow rate rather than pressure, which is why we measure your incoming main before recommending a conversion.
