- Provide the boiler make, age and any fault code.
- Say how many radiators or heating zones are affected.
- For replacement work, list hot-water demand and property size.

St Helens smoke-control rules
Most of the borough is in a Smoke Control Zone, which matters for solid-fuel heating
Boiler and radiator repairs are different from stove or solid-fuel projects. St Helens Council says the vast majority of the borough is within a Smoke Control Zone, so the appliance and fuel rules should be checked before installing or altering solid-fuel heating.
Wood and logs need an exempt appliance in a smoke-control area
St Helens Council says unauthorised fuels such as ordinary wood, peat and bituminous house coal cannot be burned in a fireplace within a Smoke Control Area. Clean wood or logs require a Defra-approved exempt appliance.
Boilers and radiators can also fall within Building Regulations
The council's planning guidance lists new boilers and radiators among home improvements that will probably require Building Regulations approval. For installation work, ask how notification, commissioning and any competent-person certification will be handled.

Give the engineer enough system detail to triage the visit
A boiler fault in Sutton, cold radiators in Parr and a stove project around Rainford are very different jobs. Include fuel type, controls, fault codes and whether heating or hot water has failed completely.
For gas work, use an appropriately registered engineer. For solid-fuel work, also check whether the exact property is inside a Smoke Control Area and whether the proposed appliance and fuel are permitted.

Before you hire

Check registration
For gas work, verify the engineer is appropriately Gas Safe registered for the work being undertaken.

For recurring faults, understand the cause before repeatedly replacing individual parts.
Compare controls and commissioning
For new systems, include controls, balancing, water treatment and commissioning in the agreed scope.
