Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Highlights
“Arranged a boiler service after buying a new house that hadn’t been lived in for 2 years - Jason couldn’t have been any more informative, offered advice on managing an old boiler, showed me how to top up pressure and walked me through the components. Competitive pricing considering how far above and beyond Jason went. Property is being renovated so I know exactly who to call to replace and relocate my boiler when these works commence.”
“My old boiler broke down. Having used Jason before, for servicing over the years, I called hm. His response was prompt and helpful and we arranged a date for a new boiler. Trusting his advice, he duly installed it yesterday and , at my request, added lagging to my condensate pipe plus a necessary replacement to a leaky radiator. He explains everything as he goes through the installation process, and is really pleasant and helpful. I highly recommend him.”
“The work was carried out quickly and efficiently. J C Gas can be totally relied upon.”

Gas work is restricted by law to Gas Safe registered engineers. If they'll touch a boiler or any gas appliance, confirm they're currently on the register before you hire - it's free and takes a minute.
By law, anyone working on your gas appliances must be on the Gas Safe Register. Ask to see their Gas Safe ID card and check the licence number at gassaferegister.co.uk before they start.
✓
Never let an unregistered person touch your gas: unsafe gas work risks carbon monoxide poisoning, fire and explosion, and is a criminal offence.
✓
For a boiler or appliance install, get the work and price in writing and keep the Gas Safe / Building Regulations certificate they are required to give you.
