Frequently asked questions — heating upgrades, Lower Nazeing
Where exactly are you based?▾
We're based in Harlow and cover everything within roughly 25 minutes — the CM, EN and SG postcodes that make up West Essex and East Herts.
Are you a small team or a big firm?▾
Small family team. The person quoting you is the person doing the work — there's no sales rep, no sub-contracting, no call centre.
Will a smart thermostat actually save money?▾
Yes — typically 8–12% off heating bills if you use the scheduling and zone features properly. Hive and Nest both pay back inside two years for most households.
Do I really need a power flush?▾
If radiators have cold patches, your boiler is noisy, or you're fitting a new boiler to an older system, yes. Otherwise a chemical flush and magnetic filter is often enough.
