Fixed prices where possible. Reply within the hour. Local coverage ## Genuinely local to Greater London Our Greater London coverage is deliberately focused. Rather than promise all of London and turn up late, we cover the NW and W boroughs we can genuinely reach from our WD19 base without compromising response time — plus selected central jobs by appointment for existing customers. ### Coverage in Greater London Regular coverage across NW (Hendon, Cricklewood, Kilburn, Willesden), W (Ealing, Acton, Chiswick — by appointment) and the London-side of the HA and UB postcodes. Central London (W1, WC, N1) is possible for existing customers and planned installations, not emergency call-out. ### Property types we work on London housing is enormously varied — Victorian and Edwardian terraces across most inner boroughs, 1930s semis further out, purpose-built mansion blocks in NW, and a large stock of modern flats. Combi boilers dominate flats and smaller terraces; system boilers with unvented cylinders are more common in the larger family homes. ### Response time to Greater London London response times depend on postcode — same-day on most jobs by appointment. Regular London work in NW, W and outer boroughs bordering Hertfordshire. ### Typical Greater London jobs Typical London jobs are boiler replacements in flats and Victorian conversions where flue routing is the deciding factor, radiator upgrades in period properties, and full heating replacements in leasehold blocks where compliance and paperwork have to be right first time. ## Services we offer in Greater London The full Premier Heating range is available across Greater London — from same-week servicing to full boiler and cylinder replacements.

Here are the specific issues we come across most often across Greater London and how we handle them. ### Flue routing in leasehold flats and mansion blocks Flue positioning in London flats is often the deciding factor between what's possible and what isn't — building rules, party walls and neighbour consent all come into it. We plan the flue before we quote, and we won't take on a job that can't be finished compliantly. ### Very old lead and iron pipework in period property A lot of London Victorian and Edwardian stock still has runs of old lead or iron pipework in the primary heating circuit. We identify these on survey and re-pipe critical sections in copper as part of any boiler replacement. ### Hard water on the domestic hot-water side London tap water is hard by any UK standard. Combi boilers scale on the DHW plate heat exchanger surprisingly quickly here — we fit an inline scale reducer as standard on every combi install and recommend a limescale flush on boilers more than five years old. ### Communal heating and district-system quirks Some London blocks run communal heating with heat interface units (HIUs) rather than individual boilers. These aren't strictly our specialism, but we can advise on whether an HIU is genuinely faulty or whether the block's plant is the actual cause of a problem in your flat. ## How we work — every job, every postcode The same clear process on every Greater London job, whether it's a boiler service or a full system replacement. 1. 01 ### Call or enquire Speak directly with Matt — no gatekeepers, no scripts. 2. 02 ### Free on-site quote Fixed price emailed the same day, 24 hours at the latest. 3. 03 ### Book the work Card, cash or bank transfer.
