I cannot recommend Tim enough if you need your boiler replaced. He was professional, kind, and super helpful - taking the time to answer all my questions. And he did a great job! Tim clearly knows his craft. It's been almost 2 months since he completed the job and I forgot to write this review because our heating has been been working so well I don't even think about it! We look forward to continuing to work with him.

Gas Work- 31 Jan 2018
Really impressed with Winston's work, would definitely recommend him, and would use him again if needed. We posted a job on MyBuilder as we urgently needed to replace our boiler. Winston came round at 9pm that same evening and spent an hour talking us through our options in detail and in layman's terms. Most importantly he was able to start work straightaway, and was happy to work on the weekend as we have a 6 month old and urgently needed hot water. His quote was fair and his work was to a high standard. Also very polite. All round top fella.

Are you Gas Safe registered?

What experience do you have with this type of job?

Whether you need a boiler installation, central heating repair, or a gas safety check, look for someone who has completed similar work recently. Experience with your specific appliance brand or system can help avoid costly mistakes.

Can you provide a detailed written quote?

A professional gas engineer in Harrow, Greater London should offer a clear, itemised quote covering labour, parts, call-out fees, and VAT. This avoids unexpected costs and lets you compare prices easily between engineers.

Do you offer any warranty or guarantee?

Ask whether the engineer guarantees their workmanship and if the manufacturer provides a boiler or parts warranty. Many gas engineers in Harrow, Greater London back their work for 12 months or more.

Do you offer emergency call-outs?

What are your charges for emergency or out-of-hours work?

Many Harrow, Greater London gas engineers charge a higher rate for evenings, weekends, or emergencies. You should be aware of these rates in advance to avoid unexpected costs if something goes wrong outside normal working hours.

Will you provide a Gas Safety Record after the work?

For installations or inspections, your Harrow, Greater London gas engineer should issue a Gas Safety Record (CP12) confirming the appliance or system has been checked and meets legal safety standards. Be sure that the engineer you choose will do so, if required for the job.
