Map the rooms to the controls before choosing a repair
If one floor or an annex has no heat while the main house is comfortable, identify which controller serves each area and whether hot water is affected too. Mention separate boilers, cylinders or other equipment only if known; there is no need to open cupboards containing unsafe or inaccessible equipment to investigate.
A multi-zone enquiry should distinguish a control problem from a wider loss of heat. That can help avoid booking a repair for the wrong appliance or assuming all circuits must be altered. We explain the initial assessment and any follow-on work, with time and labour discussed before approval. Gas work requires an engineer registered and competent for the relevant appliance and task.
Gas work. Any work on gas appliances or pipework must be carried out by an appropriately qualified, Gas Safe registered engineer. Tell us what the job involves and we will discuss how it will be handled before booking.
St John’s Wood extends this coverage into prime inner London. For a house, mansion flat or property with an annex, explain which building and services are involved. A larger plot does not establish whether systems are separate, connected or suitable for a particular repair.
Mention gated access, side passages and the distance from the entrance to the equipment. Check whether drainage access or heating equipment is reached through another occupier’s space, and arrange permission rather than assume it will be available.

Good to know.
Can one heating zone fail while the boiler still works?
Yes, an individual circuit or its controls may behave differently from the rest of the system. That is a reason to assess the zone arrangement, not evidence by itself of a particular failed part.
What does heating cost in St John’s Wood?
£120 + VAT per hour (£144 inc VAT), with a one hour minimum. Before any extra work we give an estimated duration and expected labour cost for you to agree.
