Frequently Asked Questions
No job is too big or too small. Whether you need a quick plumbing fix or a full boiler installation, our engineers are ready to help across Croydon and South London.
How quickly can you respond to an emergency?
We offer 24/7 emergency call-outs across Croydon and South London. In most cases, our engineer will be at your door within 60 minutes of your call. We handle burst pipes, gas leaks, boiler breakdowns, and electrical faults around the clock — including weekends and bank holidays.
Are your engineers Gas Safe registered?
Yes, absolutely. Every engineer who carries out gas work at DCN Serve Tech is fully Gas Safe registered. You can verify our registration number directly on the Gas Safe Register website. We take safety seriously and never compromise on compliance.
Do you charge a call-out fee?
For standard, non-emergency work, there is no call-out fee. We provide free, no-obligation quotes before any work begins. For after-hours emergency call-outs, a small call-out charge may apply, but this is always communicated upfront before we attend.
What areas do you cover?
We cover Croydon and the wider South London area, including Bromley, Thornton Heath, Norbury, Crystal Palace, Streatham, Brixton, Mitcham, Lewisham, Penge, Beckenham, and more. Visit our Areas page for a complete list of locations.
Can you help landlords with gas safety certificates?
Yes, we specialise in landlord services. We provide annual CP12 gas safety certificates, boiler servicing, and compliance reports required by law for rental properties. We work with individual landlords and letting agents across London.
How much does a new boiler installation cost?
The cost of a new boiler depends on the type and size of system required, the complexity of the installation, and your property. We offer free surveys and competitive quotes. Finance options may be available for qualifying customers. Contact us for a personalised estimate.

"DCN TechServ came out the same day for our boiler emergency. The engineer was professional, explained everything clearly, and had the heating back on within a couple of hours. Brilliant service and very fair pricing. Highly recommend."

Had a burst pipe at midnight and they were at my door within the hour. Fixed the leak, minimised the damage, and even helped clean up. Can’t thank them enough for their professionalism.
