What affects air source heat pump costs in London
Tradespeople in London typically charge £240 to £340 a day, which is 25% above the UK average and the single biggest reason prices here differ from the national figure.
Inner London is dominated by Victorian and Edwardian terraces and by conversions of them into flats, so most jobs involve a party wall and a neighbour. Outer London is largely interwar semi-detached, with substantial post-war blocks and a steady supply of recent high-density flats. Solid-wall construction is common inside the North and South Circular, which rules out cavity insulation and pushes work towards internal or external wall systems.
London is the driest part of the UK at roughly 600mm of rain a year, a little over half the UK average. Damp and roof wear are less pressing here than almost anywhere else. Overheating is the live problem instead: the urban heat island keeps the city several degrees warmer than the surrounding countryside on summer nights, which is why cooling work is more common in London than in any other region.
Planning and building regulations in London
London has more conservation areas than any other region, and in much of the inner boroughs permitted development rights have been removed by Article 4 directions. Assume you need to check before changing anything visible from the street. The Party Wall etc. Act 1996 applies to most terraced and semi-detached work, and serving notice properly takes two months, so it belongs at the start of the programme rather than the end.
