Care & maintenance
Keep it running — and keep the guarantee valid.
A little attention through the year keeps your heating reliable when you need it most — and keeps a Worcester Bosch guarantee valid. Here's what the Roost team suggests keeping an eye on, season by season, whether you're on a gas boiler, an LPG system or an air source heat pump.
Your boiler guarantee
Up to 12 years, explained in three steps.
A 12-year guarantee sounds great — but it's worth knowing how it works, and why it's only available through an accredited installer like Roost.
01
Fitted by an accredited installer
Only a Worcester Bosch Accredited Installer can register the longest guarantees. Because Roost holds that accreditation, the Greenstar boilers we supply and fit qualify for up to 12 years of parts & labour cover.
02
Registered on the day
We register the guarantee with Worcester Bosch when the boiler is commissioned, so the cover is in place from the start — you don’t have to do the paperwork or chase it up.
03
Kept valid with an annual service
The guarantee stays valid as long as the boiler is serviced each year. We’ll remind you when yours is due and carry out the 25-point service — or fold it into a Boiler Care Plan — so the cover never lapses by accident.
Roost care plans
Spread the cost, skip the queue.
A care plan turns looking after your heating into one small, predictable monthly or annual figure — and puts you near the front of the queue if something goes wrong.
from £9.50 / month
Boiler Care Plan
Your annual 25-point service and priority call-out, with optional add-ons for boiler repair, wider system repair and cylinder service.
annual
Landlord Boiler Service Plan
Compliance servicing for rental properties, so gas safety and boiler upkeep are booked in and handled on time across your portfolio.
annual
Heat Pump Service Plan
Yearly maintenance for air source heat pump owners that keeps the system at its designed efficiency, whether we fitted it or not.
Season by season
Small habits that save an avoidable call-out.
Autumn
Get ahead of the heating season- Book your annual boiler service before the cold sets in — it's the cheapest way to avoid a mid-winter breakdown, and it keeps a manufacturer's guarantee valid. A Boiler Care Plan folds it in from £9.50 a month.
- Bleed radiators that are cold at the top: trapped air means wasted gas and rooms that never quite warm up.
- Fire the heating up for a full cycle now, while an engineer can still reach you without a winter queue.
Winter
Keep it running through the cold- Keep your boiler's condensate pipe from freezing — lag any run that passes through a cold garage or loft, a common cause of a boiler locking out on the frostiest mornings.
- A well-designed air source heat pump works down to around -20°C, so don't panic if it runs longer in a cold snap — that's it doing its job efficiently.
- Going away? Leave the heating ticking over on a low frost setting rather than switching it off completely, and set it on your smart control before you leave.
Spring
Check what winter left behind- Look around the boiler, cylinder and under sinks for any signs of a slow leak or corrosion that built up over winter.
- Cold spots low down on radiators can mean sludge in the system — a power flush restores flow and protects the boiler.
- This is a good, quiet time to think about a new boiler or an air source heat pump — engineers have more room in the diary than in autumn, and we can handle the £7,500 grant paperwork.
Summer
The best time for bigger work — and for air-con- Summer is the ideal time for an air conditioning installation, so a bedroom is comfortable before the first heatwave — ask about 0% finance.
- Solar thermal panels quietly do their best work now; if your hot water from the roof has dropped off, it's the right time to have the system and antifreeze checked.
- Run the heating briefly even in warm months — it stops pumps and valves seizing while they sit idle.
