Heating done properly, explained plainly, and tidied up after — the reason 242 people gave us five stars.
Roost Heating has looked after homes and landlords across Winchester and Hampshire since 2017. Founder Tareq brings 20 years in engineering, and the engineers you'll actually meet — Christian, Max, Aidan and Jack — are all directly employed and DBS-checked. We don't use subcontractors, so the person in your home is accountable to us.
We're a Worcester Bosch Accredited Installer, Gas Safe registered and MCS certified — which means we can look after gas, LPG and commercial boilers, design and install air source heat pumps with the £7,500 grant handled, and register a boiler guarantee of up to 12 years. Read the reviews and the same words keep coming back about Christian and the team: knowledgeable, tidy, on time, and a pleasure to deal with.

Why Hampshire homeowners & landlords choose Roost
Accredited, directly employed, and rated five stars every single time.
Anyone can call themselves a heating engineer. Here is exactly what stands behind Roost, and why each of these things matters when it's your home and your money.
Accredited & registered
Worcester Bosch Accredited Installer
Accreditation means Worcester Bosch trust our workmanship enough to let us register a 12-year parts & labour guarantee on every Greenstar boiler we fit — a length of cover only accredited installers are allowed to offer, and the clearest sign a manufacturer stands behind our work.
Gas Safe Registered
By law, only a Gas Safe registered engineer may touch your boiler, gas appliances and flues. It's the single most important thing to check before letting anyone near your gas — and every gas job we do is carried out to that standard, from a CP12 certificate to a full boiler install.
MCS Certified for heat pumps
MCS certification is what unlocks the £7,500 government Boiler Upgrade Scheme grant on an air source heat pump. It means our renewable design and installation is independently assessed — and we handle all the grant paperwork for you.
Nest Pro Elite Installer
The top tier of Google Nest's installer programme, so your smart heating controls are set up and commissioned by an engineer the manufacturer has trained and recognised — not fitted and forgotten.
The way we work
9 years, one perfect rating
Roost has looked after Hampshire homes since 2017, and every one of our 242 Google reviews is five stars. That's not luck — it's the same engineers, turning up on time and doing the job properly, year after year.
DBS-checked, directly employed engineers
Every engineer who comes to your home — Christian, Max, Aidan, Jack — is a directly employed member of the Roost team and DBS-checked. We never send subcontractors, so the person on your doorstep is accountable to us and to you.
Trustmark approved · HIES consumer code
Trustmark is the government-endorsed quality scheme for tradespeople, and HIES gives you consumer-code protection on renewable installations. Together they mean your deposit, your workmanship and your guarantee are all independently backed.
In their words
“The work he carries out has always been excellent.”
★★★★★ — Brian Appleton, April 2026, via Google
“I would highly recommend Roost for any boiler maintenance and repairs. The team booked me in quickly and efficiently. When Christian attended, he was knowledgeable, efficient and a pleasure to deal with. All repairs were carried out to time, clean and cleared up without any issues at all. Great job!”
“Chris was really helpful. He replaced our underfloor heating valve and our hot water one and explained aspects of our new heating system that I didn't fully understand. Will definitely call on Roost again.”
“Roost Heating are a great company. Engineers who care about you, your property and your appliances. They are efficient and polite. We needed a new boiler - no problem, a new radiator - no problem. A shout out to Chris who comes to do our service. Thank you.”
“The team at Roost were so helpful in helping me resolve my hot water issues - helping me diagnose the issue and ultimately (selflessly) pointing me towards the boiler manufacturer warranty as the way to resolve the issue. I was really grateful for their kind and responsive support.”
Recent jobs
The job, and what the client said.
The same engineer, every service, for years
The job — A homeowner who wanted their boiler serviced properly and reliably each year — by someone who turns up when they say they will and does the job to a consistent standard, not a different face every time.
What Roost did — Christian has carried out this customer's annual service for years, turning up on time or letting them know in advance if he's running late — the kind of continuity you only get from a directly employed team rather than subcontractors.
“We have had our boiler serviced by Roost for a number of years now. And it has usually been Christian who has carried out the service. As usual he has turned up on time or if he's running late he advises us accordingly. The work he carries out has always been excellent. Over the years we have built up a rapport with him and we cannot recommend him enough.”

An underfloor heating valve put right, and the system explained
The job — A home with a faulty underfloor heating valve and a hot water valve that needed replacing — and an owner who wanted to actually understand their newer heating system rather than just have it fixed.
What Roost did — Chris replaced both the underfloor heating valve and the hot water valve, then took the time to explain the parts of the system the customer wasn't sure about — the sort of unhurried, plain-English handover we're known for.
“Chris was really helpful. He replaced our underfloor heating valve and our hot water one and explained aspects of our new heating system that I didn't fully understand. Will definitely call on Roost again.”
