No one job is the same, so builder prices in the UK 2026 vary massively. This can be a day of work fixing something small or running to an extension over several months with multiple trades. In fact, to say that anything at all can be “average” is a pointless exercise. The price will depend on the following factors:
Type and size of project
A knock through, a kitchen refurbishment, a loft conversion and rear extension – they will all need different skills at various times as well as materials. Larger projects require more coordination and site management as well.
Labour and day rates
Although a lot of builders price by fixed quote, labour still sits under that. Price differs per location, demand and whether or not it’s with a small family team vs. larger company.
Materials and specifications
There could be a massive variation from your choices e.g. standard or premium windows, insulation levels between floorings and kitchens and bathroom suites etc. Upgrades will add up even faster.
Access and site conditions
Narrow driveways, terraced houses, parking restrictions and short working hours can all impact a project’s timeline and cost. For advice from Exeter Builders, contact https://www.silverferndevelopments.co.uk/exeter-builders/
Structural engineering and latent defects
Things like steel beams, drainage changes, damp and rotten timbers can often be hidden away until the works begin as well as old electrics etc.
Permissions and compliance
Time to prepare, and time for the professionals to get all permissions in order – building regs, party wall matters etc. plus inspections all take time in reality.
Make sure to ask the right questions and obtain an itemised quote, realistic payment plan as well as clear indication of what is not included in the estimate. The lowest bid is not always the best price - clarity and craftsmanship almost always deliver more down the road.
