Heating Engineers in St Albans
Compare quotes from heating engineers in St Albans, Harpenden, Marshalswick and London Colney for boiler replacement, servicing, repairs and radiators.
Period homes and extended family houses
Large extended homes often have several bathrooms, so system boilers with unvented cylinders are popular. Zoning can help keep large homes comfortable without heating unused rooms.
Conservation areas cover much of the old city, and some homes are listed, which can affect flue options.

St Albans' cathedral city centre, Victorian terraces around the station, and large inter-war houses in Marshalswick and Harpenden make it one of Hertfordshire's most varied places to heat. Many homes are large and well extended.

The local picture: East of England
The East of England mixes commuter towns that are almost entirely on mains gas with a large rural area where many homes are off the gas grid. In the towns, boiler swaps and servicing dominate; in the countryside, oil-fired boilers, LPG and electric heating are common, so it's worth saying what fuel you use when you ask for quotes.
Gas work is not a DIY job: by law it must be carried out by a Gas Safe registered engineer. Oil boilers are usually handled by OFTEC-registered technicians, and electrical work by a qualified electrician. How to check an engineer.
