Fast Boiler Repairs – £149 FIXED PRICE LABOUR
Covering Hertfordshire & North London

Boiler Boffin provides a reliable, high-quality service at an affordable rate. All of our fees are completely transparent and you will never receive any surprise bills at the end of a visit. We charge a FIXED LABOUR FEE of £149 (Hertfordshire) and £179 (London) for any breakdown visit, covering the diagnosis and repair of the fault. We will also carry out a FREE BOILER SERVICE once the fault has been rectified. The only additional fee you will need to pay is for any replacement parts that are required.
If the fault can’t be repaired or you choose not to have the repair carried out as the parts cost is too high, then we will either refund 50% of your fee, or discount the full £149 / £179 fee from the cost of a Boiler Replacement.

5 of the Most Common Type of Boiler Repairs

If you aren’t sure whether your boiler requires a repair or replacement, here are the most common type of boiler issues and standard resolutions. If any of these issues may be impacting on your boiler, we recommend contacting a Gas Safe registered engineer to assess the problem and provide support. You should never try to fix a leaking gas boiler yourself.

  • No heating or hot water — if your boiler has a damaged component, the thermostat or controls have failed, the gas supply is interrupted or there is low water pressure, it can stop producing heat and hot water.
  • Leaking and dripping — if your boiler is leaking this could be due to a broken internal component, like a pump seal or pressure relief valve. High pressure or a faulty expansion vessel could be the cause — or a worn out seal or o-ring.
  • Kettling — if your boiler is making a strange rumbling sound like a boiling kettle, this can be caused by limescale or sludge build up inside your boiler’s heater exchanger that is restricting the flow of water.
  • Extinguished pilot light — if your pilot light keeps going out, this could be caused by a broken thermocouple that is stopping the gas supply, a draught or deposits of dirt.
  • Low boiler pressure — if the needle is below one on your boiler’s built-in pressure gauge, there might be an issue with low water pressure caused by a water leak, a faulty pressure relief valve or recently bled radiators
