Before you accept a quote
Checks before you sign a quote.
- Gas Safe registration. The engineer must be Gas Safe registered, and you are entitled to see the card. How to choose a boiler installer
- What is included. A fixed price naming the boiler and flue, a full system flush (not a rinse), a filter, controls, making good and removal of the old boiler.
- Warranty. The warranty length and what keeps it valid, in writing.
- Cost in context. Compare like for like. A price far below the usual range is usually missing something on that list. New boiler cost in Hertfordshire

Barnet questions, answered
Do you cover Barnet (EN4, EN5)?
Yes. Datum Climate covers Barnet (EN4 and EN5), along with nearby Potters Bar, Borehamwood and St Albans, as part of our South Hertfordshire and London area. Book a free survey and we confirm your postcode and a provisional slot personally. Your price is then fixed in writing and does not change.
Should a boiler quote in Barnet include a system flush?
Yes. A proper quote names a full system flush, not a rinse, plus a magnetic filter, because fitting a clean boiler to a dirty system is a common way warranties get refused. If a quote is vague on either, ask before you accept. Our quotes spell it out in writing.
Do you do landlord gas safety certificates in Barnet?
We cover landlord gas safety compliance, including the annual CP12 Landlord Gas Safety Record. The law requires one for any let property with gas appliances, carried out by a Gas Safe registered engineer, with a copy given to tenants within 28 days of the check. Book through our contact page.
Can you fit air conditioning in Barnet?
Yes. We fit air-to-air systems that cool in summer and heat in winter. A single-room system typically costs £1,800–£2,600 installed, and multi-room systems start around £3,990. These are guide ranges for typical installations. Your exact price is fixed in writing after a free survey.
