Always a pleasure to deal with Hertford Plumbers." > Source: Anonymous (5.0, via Checkatrade) > "We have used Rob - and Hertford Plumbers - on many occasions in the past. We had an old central heating programmer that had been in use since the year dot, and only allowed one series of timings which was not suitable for the current time. Rob replaced this with a new Hive system, as this allows multiple timings, and also used a blanking plate to cover the area where the previous programmer was located. Even assisted with setting up the timings and the App installation." > Source: Customer (5.0, via Checkatrade) ## Trades Plumber, Gas Engineer ## Services they list _Listed on public sources or the business's own website; check directly that they cover your job before you book:_ - Air Source Heat Pump Installation - ASHP - Air Source Heat Pump Servicing / Repair - ASHP - Gas Boiler Installation - Gas Boiler Servicing / Repair - Gas Central Heating Installation - Gas Central Heating Servicing / Repair - Gas Cooker Installation - Gas Safety Checks - CP12 - LPG Boiler Installation - LPG Central Heating Installation - LPG Central Heating Servicing / Repair - Smart Thermostats ## Areas covered _Towns and areas this trader lists serving.

Out-of-hours overcharging and 'while I'm here' add-ons are common complaints. - Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work. - Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start. - For the water-regulations side of plumbing, a WaterSafe-approved plumber is vetted, qualified to the water regulations and insured. You can check yours or find one free at watersafe.org.uk. - Confirm they cover your area and can actually come out in your timeframe before anything else. ## Contact - Phone: 07307 208398 - Website: http://www.hertfordplumbers.co.uk --- Source: MyTrustedTraders, https://mytrustedtraders.com/traders/hertford-plumbers-limited-2 Real public evidence only: every figure traces to a named source, and reviews are cross-checked across 2 review sources.
