Local issues
Common heating problems in St Albans homes
Listed and conservation properties
Older buildings may limit flue positions and outdoor unit placement. We plan installations carefully around the building.
Solid walls and heat loss
Victorian homes with solid walls lose heat faster. Correctly sized radiators and controls matter, and heat pumps need careful assessment.
Hard water
Hertfordshire's hard water causes limescale in boilers and cylinders.
Ageing systems
Older systems often carry sludge and mixed pipework, which a power flush can address before a new boiler.

Handover & guarantee
We explain what was done, register warranties and fix any installation issue until you're satisfied.
Victorian and Edwardian homes with solid walls lose heat more quickly than modern houses. That doesn't mean they can't be warm and efficient; it means the radiators, boiler and controls need to be sized for the actual heat loss of each room, rather than chosen by guesswork.
If you're interested in a heat pump for an older St Albans home, we start with an assessment of insulation and radiator sizes. Some homes are well suited; others need improvements first. We give you a straight answer.
For boiler replacements in period properties, flue routes deserve particular care, especially in conservation areas. We plan the position before quoting, so the installation is safe, compliant and sympathetic to the building.
Before you call, it helps to have your boiler's make and model, any fault code shown on the display and the pressure reading to hand. If you're a landlord, let us know how to arrange access with your tenant or agent. We'll explain the options and price before any work begins in St Albans, and payment is by bank transfer on invoice.
Plan ahead
A simple heating checklist for St Albans homeowners and landlords
Late summer: service the boiler
Book your annual boiler service before the heating goes on. Small faults found in September are far cheaper to fix than a breakdown in January, and the service record keeps your warranty valid. Servicing starts from £100.
Autumn: check radiators and controls
Turn the heating on early to check every radiator in your St Albans home heats evenly. Cold patches at the bottom point to sludge; cold at the top means air. Make sure timers and thermostats are set for winter routines.
All year: keep certificates current
Landlords with property in St Albans need a Landlord Gas Safety Certificate every 12 months. Diary the renewal date and book a combined certificate and boiler service from £150 to cover both in one visit.
