- Provide the boiler make, age and any fault code.
- Say how many radiators or heating zones are affected.

Portsmouth heating context
Building Regulations apply to heating work, while part of Portsmouth is also a smoke-control area
The right compliance route depends on the appliance and fuel. Portsmouth Building Control covers heating and energy standards, while local smoke-control restrictions matter for solid-fuel and wood-burning appliances in the affected area.
Heating installations fall within Building Regulations standards
Portsmouth City Council says Building Regulations cover heating, insulation, energy conservation and related building services. For boiler replacements or significant heating alterations, ask who is responsible for notification, commissioning and compliance paperwork.
The south-west corner of Portsmouth is a smoke-control area
Portsmouth City Council says the south-west corner of the city is a smoke-control area, limiting fuel use to smokeless fuels except where approved combustion equipment is used. If the project involves a stove or other solid-fuel appliance, check the property against the council map before choosing equipment.

Give the exact system details
A boiler fault, full central-heating replacement, radiator move and solid-fuel installation need different skills, parts and compliance routes. Include the make, model and fuel where known.
Match the engineer to the fuel and appliance. Ask for the qualifications and registration relevant to the work rather than assuming every heating engineer covers every system type.

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.
