Compare the whole heating-system scope
A replacement appliance should not be priced in isolation from controls, emitters, water quality, pipework and the condition of the existing system.
- 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.
- Confirm registration, controls, flushing, commissioning and certificates in the quote.

Cardiff heating and clean-air context
Cardiff currently has no smoke-control areas, but heating work still has compliance requirements
Cardiff differs from many English cities: the council's 2025 air-quality progress report states that there are no smoke-control areas in Cardiff. That does not remove Building Regulations, appliance-safety or statutory nuisance responsibilities.
Cardiff's 2025 air-quality report confirms no smoke-control areas
Shared Regulatory Services, reporting for Cardiff Council, states that Cardiff has no smoke-control areas and therefore no smoke-control-area appliance restriction. It still reminds residents about statutory smoke nuisance and recommends cleaner appliance choices. Check the current position before a solid-fuel installation because air-quality rules can change over time.

Heat-producing appliances can fall within Building Regulations
Cardiff Council's Building Control charges and guidance cover controlled services and fittings and specifically refer to solid or dual-fuel heat-producing appliances. Ask the installer what notification, competent-person certification or Building Control route applies to the actual appliance and fuel.

Give the exact appliance and fuel
A boiler fault, radiator move, full central-heating replacement and wood-burning stove installation need different skills, parts and compliance routes. Include the make, model and fuel where known.
No smoke-control area does not mean no rules. Ask for the registration or competence relevant to the actual appliance and confirm what certification or Building Control evidence will be provided on completion.

Before you hire
What should you check before hiring a heating engineer?
Match the engineer's competence to the fuel and work, and compare the full system specification rather than just appliance price.
Check registration
For gas work, verify the engineer is appropriately Gas Safe registered for the work being undertaken.
Ask what diagnosis supports the repair
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.
