Surbiton and surrounding areas
In Surbiton, commercial premises range from street-level shops and restaurants to offices in converted and modern buildings, many with managing agents and landlord consents to work through.
That includes premises in KT5 and KT6 and the surrounding districts. We also cover New Malden, Chessington and East Molesey, all within easy reach of Surbiton. Buildings across London range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.
What is included
- Room-by-room heat gain and heat loss calculations
- System options with pros, cons and budget costs
- Layout drawings for units, pipework and condensate
- Electrical load and supply requirements
- Written specification for pricing
