Building Services in Sleaford & Across Lincolnshire

As a rough guide, a single-storey extension in Lincolnshire usually works out around £1,800–£2,800 per m² — so roughly £40,000–£70,000 for a typical 20m² build. A two-storey extension often costs a little less per m², because the foundations and roof are shared. VAT at 20% applies to most extension work, and we price every job individually after a free site visit.

Often you won’t. Many single-storey rear extensions fall under Permitted Development (up to 4m for a detached house, 3m for others, within the size limits), so they don’t need full planning permission — though Building Regulations approval is still required. Conservation areas and listed buildings have tighter rules. We sort the drawings, Building Control and any planning application for you.

On site, a single-storey extension typically takes 8–16 weeks and a two-storey 14–24 weeks. Before we break ground there’s usually design, structural drawings and any approvals to allow for — often another 8–12 weeks. We agree a clear programme up front and keep you posted at every stage.

Yes. We manage architectural and structural drawings, Building Regulations sign-off and any planning application, so you’ve got one accountable point of contact from first sketch to final handover instead of juggling separate trades and consultants.

A dormer loft conversion is usually somewhere around £30,000–£55,000 depending on type and size, while a garage conversion is a more affordable way to add a room, often £8,000–£18,000. Both are quoted individually once we’ve checked head height, structure and what you want from the space.

Yes to all three. We carry full public liability and employer’s liability insurance, hold recognised industry accreditations, and back every project with a 10-year workmanship guarantee. We’re happy to show our paperwork before you commit to anything.

We’re based in Sleaford and work across roughly a 25-mile radius — Lincoln, Grantham, Boston, Spalding, Bourne, Newark and the surrounding villages. If your town isn’t on the list, give us a call anyway; there’s a good chance we can still help.

Always. Every project starts with a free site visit and a proper chat about what you’re after, followed by a clear, itemised written quote with no hidden extras and no pressure to go ahead.

There is no single duration because the programme depends on planning, site conditions, access, utilities, the number of plots and how the work is phased. LME agrees the sequence around the specific development and provides progress updates as each plot moves from groundworks into the main build.

Some building work can continue in light rain, while other tasks need to pause or be protected. The team checks the forecast, covers vulnerable work and reviews any affected brickwork before continuing. Safety and the quality of the finished work come first.
