Local Homes and Common Boiler Problems in Northwood
Northwood’s housing includes planned interwar estates and substantial 1930s private development in Northwood Hills.
Interwar Homes in Northwood and Northwood Hills
Gatehill Farm Estate developed from the 1930s and is an Area of Special Local Character. Much of Northwood Hills’ private housing was also built during that decade. Where older heating systems remain, sludge and pressure loss warrant investigation; the building’s age alone cannot identify the fault.
Homes in Northwood, Frithwood

Frequently Asked Questions
Does Northwood’s 2026 HMO licensing affect the gas safety check?
Licensing adds a requirement to provide an annual gas safety certificate to the council where gas is supplied; it does not replace existing gas safety duties. Hillingdon’s borough-wide additional HMO licensing began on 24 August 2026. Mandatory HMO licensing continues.
Do you cover Northwood Hills as well as Northwood?
Yes, we cover Northwood Hills as well as Northwood within HA6. Call with your full address and explain whether you need boiler servicing, a breakdown repair or help with radiators. Our phone line is answered 24 hours a day, seven days a week.
Can you repair my boiler the same day in Northwood?
Same-day appointments are available in Northwood, but completing a repair depends on the fault and any parts needed. Tell us the boiler make, model and displayed code when calling. We can discuss availability and what the engineer will need to investigate.
How often should a boiler in a Northwood home be serviced?
Arrange annual boiler servicing, following the manufacturer’s instructions for your appliance. This applies whether your boiler serves an interwar house or another Northwood home. Keep service records and check any manufacturer warranty conditions. A developing fault needs attention rather than waiting for the next service.
