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. - Confirm they cover your area and can actually come out in your timeframe before anything else. - Read recent reviews for reliability and turning up on time, not only the quality of the work. ## Contact - Phone: 07830 352578 --- Source: MyTrustedTraders, https://mytrustedtraders.com/traders/denver-services-limited-2 Real public evidence only: every figure traces to a named source and is cross-checked.
