Comparing House Extension Contractors

Compare quotes for house extensions with Top TradespeopleFinding a local contractor to build an extension is difficult. You need to be sure the company you hire is suitable for a project carried out to a high standard, compliant with building regulations, and planning permissions.  We provide a homeowner service where customers compare up to 4 quotes for extensions.  Request quotes using the form above.  Choose 'extension builders', then type of extension needed.  

Our system matches local people in our UK network near you.  Provide good project details for more interest.  Choose the best, then give reviews so other people find good companies and contractors for extensions too.




Always ask contractors quoting to build your extension for testimonials. Most good quality contractors or building companies suitable to carry out house extension building projects have good reviews and past project feedback from people.

Check websites showing examples of past projects carried out. Ask for photographs of extensions completed, or work in progress contractors have taken so you've an idea of what to expect if hiring.  Check them out. 

Don't Restrict Yourself To Locals

Nowadays a good extension builder will travel for worthwhile work with some companies nationwide.

Bungalow Extensions

Almost 10% of all homes in England and Wales are bungalows, and having a home where all rooms are on the same floor has many advantages. Most of the bungalows in the UK are older homes, sitting on larger plots with big front and back gardens. This sort of property is ideal for extending either out into the garden or up into the loft, and bungalow extensions can not only give a unique family home, they can greatly add value to the property too. 26% of UK homes have been extended since they were built, and bungalow extensions do not need to be as complicated and as costly as you may think.

Single Storey Extensions

Over 26% of all properties in the UK have been extended since they were first built, and building on an extension is one of the best ways of adding valuable living space to your property and increasing its value too. Many homes suffer from a lack of space downstairs, with plenty of bedrooms and sleeping space, but just not enough on the ground floor for the way we live today. A single storey extension onto the rear or the side of the property can transform living space and is far more cost effective than selling and moving to a bigger property. Top Tradespeople can help put you in touch with experienced, trustworthy builders and other tradespeople in your area, and make your dream of a beautiful single storey extension into reality.
