How to Choose the Right Heating Engineer / Gas-Fitter in Harrow

Before hiring, make sure you check:

• Read customer reviews – See how previous homeowners rate reliability, cleanliness, finish and whether the engineer explained things clearly.
   
• Check credentials – Ensure the person is registered with the Gas Safe Register and has public-liability insurance.
   
• Compare multiple written quotes – Get at least three to compare labour, parts, access/travel, warranty, emergency cover.
   
• Inspect the quote’s detail – Does it include labour hours, parts, guarantee, system flush/warranty? Are call-out fees/time included?
   
• Ask about hidden or extra costs – Travel, late-night or weekend work, system modifications, flue work or scaffold could add cost.
   
• Beware very low quotes – If a quote is significantly lower than average, check what is omitted (certification, high-quality materials, hidden extras).
   
• Check scope & system compatibility – Larger jobs (system upgrades, multi-zone heating, new boiler + controls) need an engineer experienced in full installations.
   
• Ask about after-jobs & warranty – Does the job include testing, commissioning, clear hand-over, documentation?
