How LG Therma V Performs in Ilford's Climate
LG Therma V performs at its best in this mild southern climate (zone 3 on our 1-7 scale). Expect seasonal efficiency in line with its certified SCOP (5.04 at 35°C, 3.75 at 55°C) and running costs at the lower end of estimates. It reaches 75°C flow, which helps existing radiators carry the load without a full re-pipe.
Noise Levels in a Built-Up Area
LG Therma V declares a sound power of 50 dB(A) for this model: the noise the unit itself emits. What you hear next door is much lower and falls with distance, and permitted development rules require the installation to meet the MCS noise standard at the nearest neighbour. In built-up areas the outdoor unit often sits close to neighbouring homes, so ask your installer to show you the noise calculation for your spot.

- Standard warranty is 3 years, and LG requires servicing 'biannually'
- No published installed price

Full grant details for London→The heating picture in London
Most homes here heat with a mains-gas boiler, and the Ofgem price cap gas rate has risen 39% since spring 2026 (5.74p per kWh in April-June to 7.97p from 1 October 2026). With £7,500 off through the Boiler Upgrade Scheme and 0% VAT until March 2027, replacing the boiler with an air source heat pump at end-of-life is now cost-competitive up front and on running costs. London homes are mostly gas-heated terraces and flats; air-to-air units (£2,500 grant) suit many flats where a wet system is impractical.
There is no gas ban in the UK and nobody is forcing the switch. The pressure is price: the Ofgem price cap gas unit rate has risen 39% since spring 2026 (5.74p per kWh in April-June to 7.97p from 1 October 2026). For Ilford households on a gas boiler, the practical takeaway is to plan ahead: keep using and repairing the boiler you have, but when it reaches end-of-life, pricing a heat pump against a new boiler (with the £7,500 Boiler Upgrade Scheme and 0% VAT in the maths) is now the rational default.
