Service Overview
Boiler Installation, explained simply.
Honest, plain-English answers, what the service is, who it's for, when you need it, and why a Gas Safe specialist matters.
What it is
A full boiler installation, survey, supply, fit, flush and commission of a new A-rated gas boiler with a manufacturer-backed warranty, certified by a Gas Safe engineer.
Who it's for
Homeowners and landlords in Oldham and Greater Manchester whose boiler is 10+ years old, repeatedly breaking down, leaking, noisy, inefficient, or no longer economical to repair.
When you need it
When your existing boiler is over a decade old, parts are no longer made, your energy bills are climbing, or your engineer has condemned the appliance for safety reasons.
Why a pro matters
A poorly sized or badly installed boiler will short-cycle, waste gas, void its warranty, and fail years early. A properly designed install, correct flue route, balanced system, magnetic filter, accurate flow rates, pays for itself in efficiency and reliability.
The Cost of Ignoring It
What it costs to wait, and the mistakes that make it worse.
An ageing or wrongly specified boiler is one of the most expensive appliances in your home to get wrong. The longer it is left, the more it costs.
If you leave it
- Energy bills 25–40% higher than a modern A-rated boiler
- Repeated breakdowns and call-out costs every winter
- Risk of carbon monoxide if heat exchangers are corroded
- Cold rooms, weak showers, and noisy kettling pipework
- Insurance and warranty claims rejected if the install isn't certified
Common mistakes
- Buying a boiler online and hiring a generalist to fit it, voids the warranty
- Picking output by guesswork rather than a heat-loss calculation
- Skipping a power flush on an old system, sludge wrecks new heat exchangers
- Ignoring flue-route regulations and gas-pipe sizing
Our Process
A clear, predictable system, from first call to sign-off.
Free home survey
We measure heat loss, check gas-pipe diameter, inspect the flue route, gas meter and radiators, and discuss your hot-water demand.
Fixed written quote
You receive a written, itemised quote as soon as possible, boiler, parts, labour, flush and commissioning, no surprise add-ons.
System prep & flush
On install day we drain, power-flush and treat the system to protect your new heat exchanger from sludge and debris.
Installation & commission
New boiler, magnetic filter, smart controls and flue fitted to manufacturer spec and Gas Safe regulations.
Demo, register & guarantee
We demonstrate the controls, register the warranty with the manufacturer, and notify Gas Safe, your certificate arrives by post and email.
The Benefits
Why customers choose C Nixon for boiler installation.
Lower bills
A-rated condensing boilers run at 92%+ efficiency, typically 25–40% cheaper to run than a 12-year-old unit.
Long warranty
Manufacturer parts-and-labour cover, typically 5 to 20 years depending on the boiler.
Single-day swap
Most combi swaps are completed in a single working day. Heating and hot water back on by evening.
Safer home
New flue, gas pipework checked, carbon monoxide and overheat protections fitted to current regs.
Quieter system
A clean, balanced system means no banging pipes, no kettling, no waking the house at 6am.
Higher resale value
A documented, registered boiler install with warranty paperwork adds value when you sell or remortgage.

In Detail
Everything you need to know about boiler installation.
We install combi, system and regular (heat-only) boilers across Oldham, Chadderton, Royton, Shaw, Failsworth, Manchester and the surrounding Greater Manchester boroughs. Every job is sized, fitted and registered to manufacturer specification.
Boilers we install
Glow-worm (Compact, Energy, Easicom), Vaillant (ecoTEC plus, ecoFIT pure) and Baxi (800, 600). We are a manufacturer-approved installer for Glow-worm and Vaillant, which unlocks the longest manufacturer warranties. Brand chosen against your property type, hot-water demand and budget, not against commission.
Combi vs system vs regular
Combi boilers suit small to medium homes with one bathroom. System boilers feed an unvented or vented cylinder for households with two or more bathrooms or high simultaneous hot-water demand. Regular (heat-only) boilers stay in larger period properties with existing tank-and-cylinder setups. We size to your home, never sell up.
Power flush & filtration
On every install we power-flush the existing system to remove sludge, fit a magnetic filter (Adey MagnaClean Pro2 or equivalent) and dose with inhibitor, the single biggest factor in warranty length and boiler lifespan.
Smart controls
We install Hive, Nest, Tado, Vaillant SensoComfort and Worcester Wave. Smart load-compensating controls extend most manufacturer warranties by 2–3 years and cut typical gas usage by 10–15%.
Landlord & rental installs
Portfolio landlords across Oldham use us for full HMO and BTL boiler swaps, fast turnaround between tenancies, digital paperwork, and CP12 certificates issued alongside the install.
Building regs & Gas Safe notification
Every install is notified to Gas Safe Register within 48 hours and your Building Regulations compliance certificate is posted directly to you, required for resale and remortgage.
