Question 1

Is a new boiler covered by a warranty?

Accepted Answer

New boilers typically carry a 5 to 12 year manufacturer warranty. It is conditional on the boiler being registered shortly after installation and serviced every year by a Gas Safe registered engineer, so keep your service records.

Question 2

What should I do if I can smell gas?

Accepted Answer

Turn the gas off at the meter, open windows, avoid light switches and naked flames, leave the property, and call the National Gas Emergency line on 0800 111 999. Do not wait for a routine appointment.

Question 3

Does a listing here mean Duplex Care Ltd is recommended?

Accepted Answer

No. Companies appear in this directory because they are on the Companies House register under a heating trade code. A listing is not vetting, endorsement, or a guarantee that the company is trading or Gas Safe registered.

Question 4

How many boiler and heating companies are there in Hertfordshire?

Accepted Answer

This directory holds 1,540 active heating businesses across 73 towns in Hertfordshire, all from the Companies House register. Barnet accounts for 89, among the county's busiest. About 34% of Hertfordshire's registered heating firms were incorporated in the last three years, so weigh incorporation date and Gas Safe registration, not just company age.
