About patio installation in Merton
Merton is a large city of around 206,000 in Greater London. The housing is mostly South West London housing leans Victorian and Edwardian with pockets of 1930s semis and modern flats. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like SW19, SW20 tend to be quicker jobs with standardised fittings. Local trade prices sit on the expensive side for UK trade work. That's mostly wage levels plus the cost of running a van and a yard in and around Greater London.
London's the deepest trade market in the country, and also the priciest. ULEZ, congestion charge, parking permits, higher van insurance — it all feeds into the day rate. Most decent firms charge a callout and central boroughs run a clear premium over zones 4 and 5. Book two to three weeks ahead if you can.
Landscaping prices move with materials. Natural stone, porcelain pavers and composite decking have all climbed sharply in the past two years. APL (Association of Professional Landscapers) is the trade body to look for. Retaining walls over a metre need Building Regulations, and raised decking over 30cm can need planning consent — worth checking before you start.
