These are guide prices for typical jobs at our baseline West Midlands rates. Home prices include VAT at 20%. Business prices exclude VAT. Your postcode moves the price up or down by region, and the guide price tool does that for you.
A guide price is not a quote. For new installations on the UK mainland we survey for free and then send a fixed price in writing. Servicing, testing and repairs are charged visits, priced before we book.
Ventilation fitted while a brand-new home is being built can be zero-rated for VAT when the work is done for the person building it; we confirm the VAT position on your quote.
