Find Trusted Builders in East London

East London has been a building site for the best part of two decades. The regeneration that started with the 2012 Olympics and spread outward through Stratford, Hackney Wick, and the Royal Docks has transformed the area, and the ripple effect continues into Walthamstow, Leytonstone, and beyond. Alongside the big commercial developments, thousands of homeowners across East London are extending, converting, and renovating their properties. Finding a builder you can trust with your home and your money is the single most important decision in any building project.

The range of work handled by East London builders is broad. Rear and side extensions are extremely popular, adding kitchen-diners and extra bedrooms to the terraced houses that dominate much of the area. Loft conversions are a close second, with dormer conversions being the most common type in areas like Leyton, Forest Gate, and Ilford. Garage conversions, internal remodelling, underpinning, and structural alterations all fall within a general builder's scope, though they should bring in structural engineers and other specialists as needed.

Planning and building control

Most extensions and loft conversions require either planning permission or compliance with permitted development rules. Building regulations approval is needed for virtually all structural work, regardless of whether planning permission is required. Your builder should be familiar with the requirements in your borough, whether that is Tower Hamlets, Newham, Waltham Forest, Redbridge, Havering, or Barking and Dagenham.

Party wall agreements are often needed in East London, where terraced and semi-detached houses mean most extensions are built adjacent to a neighbouring property. The Party Wall etc. Act 1996 sets out the process, which involves serving notice on your neighbours and, if they do not consent, appointing surveyors. Your builder cannot start work until this process is complete, so begin it early to avoid delays.

Costs

A single-storey rear extension in East London currently costs between £1,500 and £2,500 per square metre, depending on the specification. A basic 15-square-metre extension might come in at £25,000 to £35,000, while a high-spec version with bi-fold doors, underfloor heating, and a quality kitchen fit-out could reach £50,000 to £70,000. Loft conversions range from £35,000 to £65,000 for a dormer, with Velux-only conversions at the lower end of the range.

These figures include all building work, structural steels, roofing, windows, plastering, first-fix electrics and plumbing, and decoration. They typically exclude the kitchen or bathroom fit-out, flooring, and any external landscaping.

Protecting yourself

A detailed written contract is essential for any building project over a few thousand pounds. It should cover the scope of work, the price (fixed or provisional), the payment schedule, the start and completion dates, provisions for variations, and what happens if either party wants to end the agreement. JCT (Joint Contracts Tribunal) minor works contracts are widely used and protect both parties.

Never pay a large deposit upfront. A reasonable deposit is 10% to 15%, with further payments tied to completion of agreed milestones. Holding back a retention of 2.5% to 5% for three to six months after completion gives you leverage to get any snagging issues resolved. Check that your builder has public liability insurance and employers liability insurance, and verify their credentials with the relevant trade body.
