Heating and ventilation engineer — Gas Safe and F-Gas registered
Anything involving gas must be carried out by an engineer on the Gas Safe Register, and stationary refrigerant work — air conditioning, most heat pumps — requires F-Gas certification. If you want the Boiler Upgrade Scheme grant for a heat pump, the installer must be MCS certified. Expect £45–£90/hr for standard labour and £95–£190/hr for urgent out-of-hours work.
On Marketit you'll find manually vetted businesses. Describe the property, the symptoms, the system type and how urgent it is, then compare written quotes on sizing, efficiency, warranty and total installed cost.

What does a heating & ventilation engineer cost in 2026?When should you hire a heating & ventilation engineer?
No heating or hot water, unusual smells or noises, weak airflow, rising energy bills, refrigerant or water leaks, persistent condensation and damp, or concerns about indoor air quality. Get a proper heat-loss survey before replacing a boiler or fitting a heat pump.
Common mistakes to avoid
- Hiring a general handyman for gas or refrigerant work — it is illegal, uninsured and potentially dangerous.
- Buying the equipment yourself before anyone has calculated the heat loss. Oversized boilers cycle badly; undersized heat pumps struggle in cold snaps.
- Skipping commissioning and the benchmark record, which most manufacturers require for the warranty to stand.
- Forgetting the annual service — a lapsed service history voids most boiler and heat pump warranties.
- Comparing quotes on equipment price alone instead of efficiency, controls, labour warranty and running cost.
Checklist before you hire
- Check the engineer on the Gas Safe Register for gas work, and the F-Gas register for refrigerant work
- Confirm MCS certification if you're claiming the Boiler Upgrade Scheme grant for a heat pump
- Confirm public liability insurance and employers' liability if they bring a team
- Ask for a room-by-room heat-loss calculation before replacing a boiler or fitting a heat pump
- Confirm who notifies building control and issues the Building Regulations compliance certificate
- Request a written quote separating equipment, labour, controls, ductwork, removal and VAT
Frequently asked questions
Which registrations should I verify?
Use the official Gas Safe Register for anything gas — boilers, hobs, gas fires — and check the ID card on the doorstep. For air conditioning and most heat pumps, the business needs F-Gas certification. MCS certification is required for Boiler Upgrade Scheme grants.
Can I get a grant for a heat pump?
The Boiler Upgrade Scheme in England and Wales pays a fixed grant towards an air source or ground source heat pump, applied for by the MCS-certified installer and deducted from your quote. Scotland runs its own Home Energy Scotland grant and loan scheme.
Do I need building control approval?
Replacing a boiler or fitting a heat pump is notifiable under the Building Regulations. A Gas Safe or MCS registered installer can self-certify and notify building control for you, and you should receive a compliance certificate afterwards. Keep it for when you sell.
How often should the system be serviced?
Annually for boilers and heat pumps, and landlords must have a Gas Safety Record renewed every 12 months by a Gas Safe engineer. Ventilation filters need checking every one to three months. The service should cover safety controls, airflow, condensate drainage and electrical connections.

Plumber
When water is dripping under the sink or a drain backs up, you don't want to spend days searching for a firm. And before a bathroom fit-out you really don't want someone who cuts corners — that rarely shows immediately, but it has a habit of resurfacing as an insurance dispute or a leak a few years later.

Finding an available electrician with the right skills is rarely quick. Good firms are often booked weeks ahead, and when a breaker keeps tripping or your EV charger stops working, you haven't got time to ring round and wait for a cancellation.
